  • SECTION I.
  • OF THE DIFFERENT SPECIES OF PHILOSOPHY.
  • 1. Moral philosophy, or the science of human nature, may be treated
  • after two different manners; each of which has its peculiar merit, and
  • may contribute to the entertainment, instruction, and reformation of
  • mankind. The one considers man chiefly as born for action; and as
  • influenced in his measures by taste and sentiment; pursuing one object,
  • and avoiding another, according to the value which these objects seem to
  • possess, and according to the light in which they present themselves. As
  • virtue, of all objects, is allowed to be the most valuable, this species
  • of philosophers paint her in the most amiable colours; borrowing all
  • helps from poetry and eloquence, and treating their subject in an easy
  • and obvious manner, and such as is best fitted to please the
  • imagination, and engage the affections. They select the most striking
  • observations and instances from common life; place opposite characters
  • in a proper contrast; and alluring us into the paths of virtue by the
  • views of glory and happiness, direct our steps in these paths by the
  • soundest precepts and most illustrious examples. They make us _feel_ the
  • difference between vice and virtue; they excite and regulate our
  • sentiments; and so they can but bend our hearts to the love of probity
  • and true honour, they think, that they have fully attained the end of
  • all their labours.
  • 2. The other species of philosophers consider man in the light of a
  • reasonable rather than an active being, and endeavour to form his
  • understanding more than cultivate his manners. They regard human nature
  • as a subject of speculation; and with a narrow scrutiny examine it, in
  • order to find those principles, which regulate our understanding, excite
  • our sentiments, and make us approve or blame any particular object,
  • action, or behaviour. They think it a reproach to all literature, that
  • philosophy should not yet have fixed, beyond controversy, the foundation
  • of morals, reasoning, and criticism; and should for ever talk of truth
  • and falsehood, vice and virtue, beauty and deformity, without being able
  • to determine the source of these distinctions. While they attempt this
  • arduous task, they are deterred by no difficulties; but proceeding from
  • particular instances to general principles, they still push on their
  • enquiries to principles more general, and rest not satisfied till they
  • arrive at those original principles, by which, in every science, all
  • human curiosity must be bounded. Though their speculations seem
  • abstract, and even unintelligible to common readers, they aim at the
  • approbation of the learned and the wise; and think themselves
  • sufficiently compensated for the labour of their whole lives, if they
  • can discover some hidden truths, which may contribute to the instruction
  • of posterity.
  • 3. It is certain that the easy and obvious philosophy will always, with
  • the generality of mankind, have the preference above the accurate and
  • abstruse; and by many will be recommended, not only as more agreeable,
  • but more useful than the other. It enters more into common life; moulds
  • the heart and affections; and, by touching those principles which
  • actuate men, reforms their conduct, and brings them nearer to that model
  • of perfection which it describes. On the contrary, the abstruse
  • philosophy, being founded on a turn of mind, which cannot enter into
  • business and action, vanishes when the philosopher leaves the shade, and
  • comes into open day; nor can its principles easily retain any influence
  • over our conduct and behaviour. The feelings of our heart, the agitation
  • of our passions, the vehemence of our affections, dissipate all its
  • conclusions, and reduce the profound philosopher to a mere plebeian.
  • 4. This also must be confessed, that the most durable, as well as
  • justest fame, has been acquired by the easy philosophy, and that
  • abstract reasoners seem hitherto to have enjoyed only a momentary
  • reputation, from the caprice or ignorance of their own age, but have not
  • been able to support their renown with more equitable posterity. It is
  • easy for a profound philosopher to commit a mistake in his subtile
  • reasonings; and one mistake is the necessary parent of another, while he
  • pushes on his consequences, and is not deterred from embracing any
  • conclusion, by its unusual appearance, or its contradiction to popular
  • opinion. But a philosopher, who purposes only to represent the common
  • sense of mankind in more beautiful and more engaging colours, if by
  • accident he falls into error, goes no farther; but renewing his appeal
  • to common sense, and the natural sentiments of the mind, returns into
  • the right path, and secures himself from any dangerous illusions. The
  • fame of Cicero flourishes at present; but that of Aristotle is utterly
  • decayed. La Bruyere passes the seas, and still maintains his reputation:
  • But the glory of Malebranche is confined to his own nation, and to his
  • own age. And Addison, perhaps, will be read with pleasure, when Locke
  • shall be entirely forgotten.
  • The mere philosopher is a character, which is commonly but little
  • acceptable in the world, as being supposed to contribute nothing either
  • to the advantage or pleasure of society; while he lives remote from
  • communication with mankind, and is wrapped up in principles and notions
  • equally remote from their comprehension. On the other hand, the mere
  • ignorant is still more despised; nor is any thing deemed a surer sign of
  • an illiberal genius in an age and nation where the sciences flourish,
  • than to be entirely destitute of all relish for those noble
  • entertainments. The most perfect character is supposed to lie between
  • those extremes; retaining an equal ability and taste for books, company,
  • and business; preserving in conversation that discernment and delicacy
  • which arise from polite letters; and in business, that probity and
  • accuracy which are the natural result of a just philosophy. In order to
  • diffuse and cultivate so accomplished a character, nothing can be more
  • useful than compositions of the easy style and manner, which draw not
  • too much from life, require no deep application or retreat to be
  • comprehended, and send back the student among mankind full of noble
  • sentiments and wise precepts, applicable to every exigence of human
  • life. By means of such compositions, virtue becomes amiable, science
  • agreeable, company instructive, and retirement entertaining.
  • Man is a reasonable being; and as such, receives from science his proper
  • food and nourishment: But so narrow are the bounds of human
  • understanding, that little satisfaction can be hoped for in this
  • particular, either from the extent of security or his acquisitions. Man
  • is a sociable, no less than a reasonable being: But neither can he
  • always enjoy company agreeable and amusing, or preserve the proper
  • relish for them. Man is also an active being; and from that disposition,
  • as well as from the various necessities of human life, must submit to
  • business and occupation: But the mind requires some relaxation, and
  • cannot always support its bent to care and industry. It seems, then,
  • that nature has pointed out a mixed kind of life as most suitable to the
  • human race, and secretly admonished them to allow none of these biasses
  • to _draw_ too much, so as to incapacitate them for other occupations and
  • entertainments. Indulge your passion for science, says she, but let your
  • science be human, and such as may have a direct reference to action and
  • society. Abstruse thought and profound researches I prohibit, and will
  • severely punish, by the pensive melancholy which they introduce, by the
  • endless uncertainty in which they involve you, and by the cold reception
  • which your pretended discoveries shall meet with, when communicated. Be
  • a philosopher; but, amidst all your philosophy, be still a man.
  • 5. Were the generality of mankind contented to prefer the easy
  • philosophy to the abstract and profound, without throwing any blame or
  • contempt on the latter, it might not be improper, perhaps, to comply
  • with this general opinion, and allow every man to enjoy, without
  • opposition, his own taste and sentiment. But as the matter is often
  • carried farther, even to the absolute rejecting of all profound
  • reasonings, or what is commonly called _metaphysics_, we shall now
  • proceed to consider what can reasonably be pleaded in their behalf.
  • We may begin with observing, that one considerable advantage, which
  • results from the accurate and abstract philosophy, is, its subserviency
  • to the easy and humane; which, without the former, can never attain a
  • sufficient degree of exactness in its sentiments, precepts, or
  • reasonings. All polite letters are nothing but pictures of human life in
  • various attitudes and situations; and inspire us with different
  • sentiments, of praise or blame, admiration or ridicule, according to the
  • qualities of the object, which they set before us. An artist must be
  • better qualified to succeed in this undertaking, who, besides a delicate
  • taste and a quick apprehension, possesses an accurate knowledge of the
  • internal fabric, the operations of the understanding, the workings of
  • the passions, and the various species of sentiment which discriminate
  • vice and virtue. How painful soever this inward search or enquiry may
  • appear, it becomes, in some measure, requisite to those, who would
  • describe with success the obvious and outward appearances of life and
  • manners. The anatomist presents to the eye the most hideous and
  • disagreeable objects; but his science is useful to the painter in
  • delineating even a Venus or an Helen. While the latter employs all the
  • richest colours of his art, and gives his figures the most graceful and
  • engaging airs; he must still carry his attention to the inward structure
  • of the human body, the position of the muscles, the fabric of the bones,
  • and the use and figure of every part or organ. Accuracy is, in every
  • case, advantageous to beauty, and just reasoning to delicate sentiment.
  • In vain would we exalt the one by depreciating the other.
  • Besides, we may observe, in every art or profession, even those which
  • most concern life or action, that a spirit of accuracy, however
  • acquired, carries all of them nearer their perfection, and renders them
  • more subservient to the interests of society. And though a philosopher
  • may live remote from business, the genius of philosophy, if carefully
  • cultivated by several, must gradually diffuse itself throughout the
  • whole society, and bestow a similar correctness on every art and
  • calling. The politician will acquire greater foresight and subtility, in
  • the subdividing and balancing of power; the lawyer more method and finer
  • principles in his reasonings; and the general more regularity in his
  • discipline, and more caution in his plans and operations. The stability
  • of modern governments above the ancient, and the accuracy of modern
  • philosophy, have improved, and probably will still improve, by similar
  • gradations.
  • 6. Were there no advantage to be reaped from these studies, beyond the
  • gratification of an innocent curiosity, yet ought not even this to be
  • despised; as being one accession to those few safe and harmless
  • pleasures, which are bestowed on human race. The sweetest and most
  • inoffensive path of life leads through the avenues of science and
  • learning; and whoever can either remove any obstructions in this way, or
  • open up any new prospect, ought so far to be esteemed a benefactor to
  • mankind. And though these researches may appear painful and fatiguing,
  • it is with some minds as with some bodies, which being endowed with
  • vigorous and florid health, require severe exercise, and reap a pleasure
  • from what, to the generality of mankind, may seem burdensome and
  • laborious. Obscurity, indeed, is painful to the mind as well as to the
  • eye; but to bring light from obscurity, by whatever labour, must needs
  • be delightful and rejoicing.
  • But this obscurity in the profound and abstract philosophy, is objected
  • to, not only as painful and fatiguing, but as the inevitable source of
  • uncertainty and error. Here indeed lies the justest and most plausible
  • objection against a considerable part of metaphysics, that they are not
  • properly a science; but arise either from the fruitless efforts of human
  • vanity, which would penetrate into subjects utterly inaccessible to the
  • understanding, or from the craft of popular superstitions, which, being
  • unable to defend themselves on fair ground, raise these intangling
  • brambles to cover and protect their weakness. Chaced from the open
  • country, these robbers fly into the forest, and lie in wait to break in
  • upon every unguarded avenue of the mind, and overwhelm it with religious
  • fears and prejudices. The stoutest antagonist, if he remit his watch a
  • moment, is oppressed. And many, through cowardice and folly, open the
  • gates to the enemies, and willingly receive them with reverence and
  • submission, as their legal sovereigns.
  • 7. But is this a sufficient reason, why philosophers should desist from
  • such researches, and leave superstition still in possession of her
  • retreat? Is it not proper to draw an opposite conclusion, and perceive
  • the necessity of carrying the war into the most secret recesses of the
  • enemy? In vain do we hope, that men, from frequent disappointment, will
  • at last abandon such airy sciences, and discover the proper province of
  • human reason. For, besides, that many persons find too sensible an
  • interest in perpetually recalling such topics; besides this, I say, the
  • motive of blind despair can never reasonably have place in the sciences;
  • since, however unsuccessful former attempts may have proved, there is
  • still room to hope, that the industry, good fortune, or improved
  • sagacity of succeeding generations may reach discoveries unknown to
  • former ages. Each adventurous genius will still leap at the arduous
  • prize, and find himself stimulated, rather that discouraged, by the
  • failures of his predecessors; while he hopes that the glory of achieving
  • so hard an adventure is reserved for him alone. The only method of
  • freeing learning, at once, from these abstruse questions, is to enquire
  • seriously into the nature of human understanding, and show, from an
  • exact analysis of its powers and capacity, that it is by no means fitted
  • for such remote and abstruse subjects. We must submit to this fatigue,
  • in order to live at ease ever after: And must cultivate true metaphysics
  • with some care, in order to destroy the false and adulterate. Indolence,
  • which, to some persons, affords a safeguard against this deceitful
  • philosophy, is, with others, overbalanced by curiosity; and despair,
  • which, at some moments, prevails, may give place afterwards to sanguine
  • hopes and expectations. Accurate and just reasoning is the only catholic
  • remedy, fitted for all persons and all dispositions; and is alone able
  • to subvert that abstruse philosophy and metaphysical jargon, which,
  • being mixed up with popular superstition, renders it in a manner
  • impenetrable to careless reasoners, and gives it the air of science
  • and wisdom.
  • 8. Besides this advantage of rejecting, after deliberate enquiry, the
  • most uncertain and disagreeable part of learning, there are many
  • positive advantages, which result from an accurate scrutiny into the
  • powers and faculties of human nature. It is remarkable concerning the
  • operations of the mind, that, though most intimately present to us, yet,
  • whenever they become the object of reflexion, they seem involved in
  • obscurity; nor can the eye readily find those lines and boundaries,
  • which discriminate and distinguish them. The objects are too fine to
  • remain long in the same aspect or situation; and must be apprehended in
  • an instant, by a superior penetration, derived from nature, and improved
  • by habit and reflexion. It becomes, therefore, no inconsiderable part of
  • science barely to know the different operations of the mind, to separate
  • them from each other, to class them under their proper heads, and to
  • correct all that seeming disorder, in which they lie involved, when made
  • the object of reflexion and enquiry. This talk of ordering and
  • distinguishing, which has no merit, when performed with regard to
  • external bodies, the objects of our senses, rises in its value, when
  • directed towards the operations of the mind, in proportion to the
  • difficulty and labour, which we meet with in performing it. And if we
  • can go no farther than this mental geography, or delineation of the
  • distinct parts and powers of the mind, it is at least a satisfaction to
  • go so far; and the more obvious this science may appear (and it is by no
  • means obvious) the more contemptible still must the ignorance of it be
  • esteemed, in all pretenders to learning and philosophy.
  • Nor can there remain any suspicion, that this science is uncertain and
  • chimerical; unless we should entertain such a scepticism as is entirely
  • subversive of all speculation, and even action. It cannot be doubted,
  • that the mind is endowed with several powers and faculties, that these
  • powers are distinct from each other, that what is really distinct to the
  • immediate perception may be distinguished by reflexion; and
  • consequently, that there is a truth and falsehood in all propositions on
  • this subject, and a truth and falsehood, which lie not beyond the
  • compass of human understanding. There are many obvious distinctions of
  • this kind, such as those between the will and understanding, the
  • imagination and passions, which fall within the comprehension of every
  • human creature; and the finer and more philosophical distinctions are no
  • less real and certain, though more difficult to be comprehended. Some
  • instances, especially late ones, of success in these enquiries, may give
  • us a juster notion of the certainty and solidity of this branch of
  • learning. And shall we esteem it worthy the labour of a philosopher to
  • give us a true system of the planets, and adjust the position and order
  • of those remote bodies; while we affect to overlook those, who, with so
  • much success, delineate the parts of the mind, in which we are so
  • intimately concerned?
  • 9. But may we not hope, that philosophy, if cultivated with care, and
  • encouraged by the attention of the public, may carry its researches
  • still farther, and discover, at least in some degree, the secret springs
  • and principles, by which the human mind is actuated in its operations?
  • Astronomers had long contented themselves with proving, from the
  • phaenomena, the true motions, order, and magnitude of the heavenly
  • bodies: Till a philosopher, at last, arose, who seems, from the happiest
  • reasoning, to have also determined the laws and forces, by which the
  • revolutions of the planets are governed and directed. The like has been
  • performed with regard to other parts of nature. And there is no reason
  • to despair of equal success in our enquiries concerning the mental
  • powers and economy, if prosecuted with equal capacity and caution. It is
  • probable, that one operation and principle of the mind depends on
  • another; which, again, may be resolved into one more general and
  • universal: And how far these researches may possibly be carried, it will
  • be difficult for us, before, or even after, a careful trial, exactly to
  • determine. This is certain, that attempts of this kind are every day
  • made even by those who philosophize the most negligently: And nothing
  • can be more requisite than to enter upon the enterprize with thorough
  • care and attention; that, if it lie within the compass of human
  • understanding, it may at last be happily achieved; if not, it may,
  • however, be rejected with some confidence and security. This last
  • conclusion, surely, is not desirable; nor ought it to be embraced too
  • rashly. For how much must we diminish from the beauty and value of this
  • species of philosophy, upon such a supposition? Moralists have hitherto
  • been accustomed, when they considered the vast multitude and diversity
  • of those actions that excite our approbation or dislike, to search for
  • some common principle, on which this variety of sentiments might depend.
  • And though they have sometimes carried the matter too far, by their
  • passion for some one general principle; it must, however, be confessed,
  • that they are excusable in expecting to find some general principles,
  • into which all the vices and virtues were justly to be resolved. The
  • like has been the endeavour of critics, logicians, and even politicians:
  • Nor have their attempts been wholly unsuccessful; though perhaps longer
  • time, greater accuracy, and more ardent application may bring these
  • sciences still nearer their perfection. To throw up at once all
  • pretensions of this kind may justly be deemed more rash, precipitate,
  • and dogmatical, than even the boldest and most affirmative philosophy,
  • that has ever attempted to impose its crude dictates and principles
  • on mankind.
  • 10. What though these reasonings concerning human nature seem abstract,
  • and of difficult comprehension? This affords no presumption of their
  • falsehood. On the contrary, it seems impossible, that what has hitherto
  • escaped so many wise and profound philosophers can be very obvious and
  • easy. And whatever pains these researches may cost us, we may think
  • ourselves sufficiently rewarded, not only in point of profit but of
  • pleasure, if, by that means, we can make any addition to our stock of
  • knowledge, in subjects of such unspeakable importance.
  • But as, after all, the abstractedness of these speculations is no
  • recommendation, but rather a disadvantage to them, and as this
  • difficulty may perhaps be surmounted by care and art, and the avoiding
  • of all unnecessary detail, we have, in the following enquiry, attempted
  • to throw some light upon subjects, from which uncertainty has hitherto
  • deterred the wise, and obscurity the ignorant. Happy, if we can unite
  • the boundaries of the different species of philosophy, by reconciling
  • profound enquiry with clearness, and truth with novelty! And still more
  • happy, if, reasoning in this easy manner, we can undermine the
  • foundations of an abstruse philosophy, which seems to have hitherto
  • served only as a shelter to superstition, and a cover to absurdity
  • and error!
  • SECTION II.
  • OF THE ORIGIN OF IDEAS.
  • 11. Every one will readily allow, that there is a considerable
  • difference between the perceptions of the mind, when a man feels the
  • pain of excessive heat, or the pleasure of moderate warmth, and when he
  • afterwards recalls to his memory this sensation, or anticipates it by
  • his imagination. These faculties may mimic or copy the perceptions of
  • the senses; but they never can entirely reach the force and vivacity of
  • the original sentiment. The utmost we say of them, even when they
  • operate with greatest vigour, is, that they represent their object in so
  • lively a manner, that we could _almost_ say we feel or see it: But,
  • except the mind be disordered by disease or madness, they never can
  • arrive at such a pitch of vivacity, as to render these perceptions
  • altogether undistinguishable. All the colours of poetry, however
  • splendid, can never paint natural objects in such a manner as to make
  • the description be taken for a real landskip. The most lively thought is
  • still inferior to the dullest sensation.
  • We may observe a like distinction to run through all the other
  • perceptions of the mind. A man in a fit of anger, is actuated in a very
  • different manner from one who only thinks of that emotion. If you tell
  • me, that any person is in love, I easily understand your meaning, and
  • form a just conception of his situation; but never can mistake that
  • conception for the real disorders and agitations of the passion. When we
  • reflect on our past sentiments and affections, our thought is a faithful
  • mirror, and copies its objects truly; but the colours which it employs
  • are faint and dull, in comparison of those in which our original
  • perceptions were clothed. It requires no nice discernment or
  • metaphysical head to mark the distinction between them.
  • 12. Here therefore we may divide all the perceptions of the mind into
  • two classes or species, which are distinguished by their different
  • degrees of force and vivacity. The less forcible and lively are commonly
  • denominated _Thoughts_ or _Ideas_. The other species want a name in our
  • language, and in most others; I suppose, because it was not requisite
  • for any, but philosophical purposes, to rank them under a general term
  • or appellation. Let us, therefore, use a little freedom, and call them
  • _Impressions_; employing that word in a sense somewhat different from
  • the usual. By the term _impression_, then, I mean all our more lively
  • perceptions, when we hear, or see, or feel, or love, or hate, or desire,
  • or will. And impressions are distinguished from ideas, which are the
  • less lively perceptions, of which we are conscious, when we reflect on
  • any of those sensations or movements above mentioned.
  • 13. Nothing, at first view, may seem more unbounded than the thought of
  • man, which not only escapes all human power and authority, but is not
  • even restrained within the limits of nature and reality. To form
  • monsters, and join incongruous shapes and appearances, costs the
  • imagination no more trouble than to conceive the most natural and
  • familiar objects. And while the body is confined to one planet, along
  • which it creeps with pain and difficulty; the thought can in an instant
  • transport us into the most distant regions of the universe; or even
  • beyond the universe, into the unbounded chaos, where nature is supposed
  • to lie in total confusion. What never was seen, or heard of, may yet be
  • conceived; nor is any thing beyond the power of thought, except what
  • implies an absolute contradiction.
  • But though our thought seems to possess this unbounded liberty, we shall
  • find, upon a nearer examination, that it is really confined within very
  • narrow limits, and that all this creative power of the mind amounts to
  • no more than the faculty of compounding, transposing, augmenting, or
  • diminishing the materials afforded us by the senses and experience. When
  • we think of a golden mountain, we only join two consistent ideas,
  • _gold_, and _mountain_, with which we were formerly acquainted. A
  • virtuous horse we can conceive; because, from our own feeling, we can
  • conceive virtue; and this we may unite to the figure and shape of a
  • horse, which is an animal familiar to us. In short, all the materials of
  • thinking are derived either from our outward or inward sentiment: the
  • mixture and composition of these belongs alone to the mind and will. Or,
  • to express myself in philosophical language, all our ideas or more
  • feeble perceptions are copies of our impressions or more lively ones.
  • 14. To prove this, the two following arguments will, I hope, be
  • sufficient. First, when we analyze our thoughts or ideas, however
  • compounded or sublime, we always find that they resolve themselves into
  • such simple ideas as were copied from a precedent feeling or sentiment.
  • Even those ideas, which, at first view, seem the most wide of this
  • origin, are found, upon a nearer scrutiny, to be derived from it. The
  • idea of God, as meaning an infinitely intelligent, wise, and good Being,
  • arises from reflecting on the operations of our own mind, and
  • augmenting, without limit, those qualities of goodness and wisdom. We
  • may prosecute this enquiry to what length we please; where we shall
  • always find, that every idea which we examine is copied from a similar
  • impression. Those who would assert that this position is not universally
  • true nor without exception, have only one, and that an easy method of
  • refuting it; by producing that idea, which, in their opinion, is not
  • derived from this source. It will then be incumbent on us, if we would
  • maintain our doctrine, to produce the impression, or lively perception,
  • which corresponds to it.
  • 15. Secondly. If it happen, from a defect of the organ, that a man is
  • not susceptible of any species of sensation, we always find that he is
  • as little susceptible of the correspondent ideas. A blind man can form
  • no notion of colours; a deaf man of sounds. Restore either of them that
  • sense in which he is deficient; by opening this new inlet for his
  • sensations, you also open an inlet for the ideas; and he finds no
  • difficulty in conceiving these objects. The case is the same, if the
  • object, proper for exciting any sensation, has never been applied to the
  • organ. A Laplander or Negro has no notion of the relish of wine. And
  • though there are few or no instances of a like deficiency in the mind,
  • where a person has never felt or is wholly incapable of a sentiment or
  • passion that belongs to his species; yet we find the same observation to
  • take place in a less degree. A man of mild manners can form no idea of
  • inveterate revenge or cruelty; nor can a selfish heart easily conceive
  • the heights of friendship and generosity. It is readily allowed, that
  • other beings may possess many senses of which we can have no conception;
  • because the ideas of them have never been introduced to us in the only
  • manner by which an idea can have access to the mind, to wit, by the
  • actual feeling and sensation.
  • 16. There is, however, one contradictory phenomenon, which may prove
  • that it is not absolutely impossible for ideas to arise, independent of
  • their correspondent impressions. I believe it will readily be allowed,
  • that the several distinct ideas of colour, which enter by the eye, or
  • those of sound, which are conveyed by the ear, are really different from
  • each other; though, at the same time, resembling. Now if this be true of
  • different colours, it must be no less so of the different shades of the
  • same colour; and each shade produces a distinct idea, independent of the
  • rest. For if this should be denied, it is possible, by the continual
  • gradation of shades, to run a colour insensibly into what is most remote
  • from it; and if you will not allow any of the means to be different, you
  • cannot, without absurdity, deny the extremes to be the same. Suppose,
  • therefore, a person to have enjoyed his sight for thirty years, and to
  • have become perfectly acquainted with colours of all kinds except one
  • particular shade of blue, for instance, which it never has been his
  • fortune to meet with. Let all the different shades of that colour,
  • except that single one, be placed before him, descending gradually from
  • the deepest to the lightest; it is plain that he will perceive a blank,
  • where that shade is wanting, and will be sensible that there is a
  • greater distance in that place between the contiguous colours than in
  • any other. Now I ask, whether it be possible for him, from his own
  • imagination, to supply this deficiency, and raise up to himself the idea
  • of that particular shade, though it had never been conveyed to him by
  • his senses? I believe there are few but will be of opinion that he can:
  • and this may serve as a proof that the simple ideas are not always, in
  • every instance, derived from the correspondent impressions; though this
  • instance is so singular, that it is scarcely worth our observing, and
  • does not merit that for it alone we should alter our general maxim.
  • 17. Here, therefore, is a proposition, which not only seems, in itself,
  • simple and intelligible; but, if a proper use were made of it, might
  • render every dispute equally intelligible, and banish all that jargon,
  • which has so long taken possession of metaphysical reasonings, and drawn
  • disgrace upon them. All ideas, especially abstract ones, are naturally
  • faint and obscure: the mind has but a slender hold of them: they are apt
  • to be confounded with other resembling ideas; and when we have often
  • employed any term, though without a distinct meaning, we are apt to
  • imagine it has a determinate idea annexed to it. On the contrary, all
  • impressions, that is, all sensations, either outward or inward, are
  • strong and vivid: the limits between them are more exactly determined:
  • nor is it easy to fall into any error or mistake with regard to them.
  • When we entertain, therefore, any suspicion that a philosophical term is
  • employed without any meaning or idea (as is but too frequent), we need
  • but enquire, _from what impression is that supposed idea derived_? And
  • if it be impossible to assign any, this will serve to confirm our
  • suspicion. By bringing ideas into so clear a light we may reasonably
  • hope to remove all dispute, which may arise, concerning their nature and
  • reality.[1]
  • [1] It is probable that no more was meant by those, who denied
  • innate ideas, than that all ideas were copies of our
  • impressions; though it must be confessed, that the terms, which
  • they employed, were not chosen with such caution, nor so
  • exactly defined, as to prevent all mistakes about their
  • doctrine. For what is meant by _innate_? If innate be
  • equivalent to natural, then all the perceptions and ideas of
  • the mind must be allowed to be innate or natural, in whatever
  • sense we take the latter word, whether in opposition to what is
  • uncommon, artificial, or miraculous. If by innate be meant,
  • contemporary to our birth, the dispute seems to be frivolous;
  • nor is it worth while to enquire at what time thinking begins,
  • whether before, at, or after our birth. Again, the word _idea_,
  • seems to be commonly taken in a very loose sense, by LOCKE and
  • others; as standing for any of our perceptions, our sensations
  • and passions, as well as thoughts. Now in this sense, I should
  • desire to know, what can be meant by asserting, that self-love,
  • or resentment of injuries, or the passion between the sexes is
  • not innate?
  • But admitting these terms, _impressions_ and _ideas_, in the
  • sense above explained, and understanding by _innate_, what is
  • original or copied from no precedent perception, then may we
  • assert that all our impressions are innate, and our ideas
  • not innate.
  • To be ingenuous, I must own it to be my opinion, that LOCKE was
  • betrayed into this question by the schoolmen, who, making use
  • of undefined terms, draw out their disputes to a tedious
  • length, without ever touching the point in question. A like
  • ambiguity and circumlocution seem to run through that
  • philosopher's reasonings on this as well as most other
  • subjects.
  • SECTION III.
  • OF THE ASSOCIATION OF IDEAS.
  • 18. It is evident that there is a principle of connexion between the
  • different thoughts or ideas of the mind, and that, in their appearance
  • to the memory or imagination, they introduce each other with a certain
  • degree of method and regularity. In our more serious thinking or
  • discourse this is so observable that any particular thought, which
  • breaks in upon the regular tract or chain of ideas, is immediately
  • remarked and rejected. And even in our wildest and most wandering
  • reveries, nay in our very dreams, we shall find, if we reflect, that the
  • imagination ran not altogether at adventures, but that there was still a
  • connexion upheld among the different ideas, which succeeded each other.
  • Were the loosest and freest conversation to be transcribed, there would
  • immediately be observed something which connected it in all its
  • transitions. Or where this is wanting, the person who broke the thread
  • of discourse might still inform you, that there had secretly revolved in
  • his mind a succession of thought, which had gradually led him from the
  • subject of conversation. Among different languages, even where we cannot
  • suspect the least connexion or communication, it is found, that the
  • words, expressive of ideas, the most compounded, do yet nearly
  • correspond to each other: a certain proof that the simple ideas,
  • comprehended in the compound ones, were bound together by some universal
  • principle, which had an equal influence on all mankind.
  • 19. Though it be too obvious to escape observation, that different ideas
  • are connected together; I do not find that any philosopher has attempted
  • to enumerate or class all the principles of association; a subject,
  • however, that seems worthy of curiosity. To me, there appear to be only
  • three principles of connexion among ideas, namely, _Resemblance_,
  • _Contiguity_ in time or place, and _Cause or Effect_.
  • That these principles serve to connect ideas will not, I believe, be
  • much doubted. A picture naturally leads our thoughts to the original[2]:
  • the mention of one apartment in a building naturally introduces an
  • enquiry or discourse concerning the others[3]: and if we think of a
  • wound, we can scarcely forbear reflecting on the pain which follows
  • it[4]. But that this enumeration is complete, and that there are no
  • other principles of association except these, may be difficult to prove
  • to the satisfaction of the reader, or even to a man's own satisfaction.
  • All we can do, in such cases, is to run over several instances, and
  • examine carefully the principle which binds the different thoughts to
  • each other, never stopping till we render the principle as general as
  • possible[5]. The more instances we examine, and the more care we employ,
  • the more assurance shall we acquire, that the enumeration, which we form
  • from the whole, is complete and entire.
  • [2] Resemblance.
  • [3] Contiguity.
  • [4] Cause and effect.
  • [5] For instance, Contrast or Contrariety is also a connexion
  • among Ideas: but it may, perhaps, be considered as a mixture of
  • _Causation_ and _Resemblance_. Where two objects are contrary,
  • the one destroys the other; that is, the cause of its
  • annihilation, and the idea of the annihilation of an object,
  • implies the idea of its former existence.
  • SECTION IV.
  • SCEPTICAL DOUBTS CONCERNING THE OPERATIONS OF THE UNDERSTANDING.
  • PART I.
  • 20. All the objects of human reason or enquiry may naturally be divided
  • into two kinds, to wit, _Relations of Ideas_, and _Matters of Fact_. Of
  • the first kind are the sciences of Geometry, Algebra, and Arithmetic;
  • and in short, every affirmation which is either intuitively or
  • demonstratively certain. _That the square of the hypothenuse is equal to
  • the square of the two sides_, is a proposition which expresses a
  • relation between these figures. _That three times five is equal to the
  • half of thirty_, expresses a relation between these numbers.
  • Propositions of this kind are discoverable by the mere operation of
  • thought, without dependence on what is anywhere existent in the
  • universe. Though there never were a circle or triangle in nature, the
  • truths demonstrated by Euclid would for ever retain their certainty
  • and evidence.
  • 21. Matters of fact, which are the second objects of human reason, are
  • not ascertained in the same manner; nor is our evidence of their truth,
  • however great, of a like nature with the foregoing. The contrary of
  • every matter of fact is still possible; because it can never imply a
  • contradiction, and is conceived by the mind with the same facility and
  • distinctness, as if ever so conformable to reality. _That the sun will
  • not rise to-morrow_ is no less intelligible a proposition, and implies
  • no more contradiction than the affirmation, _that it will rise_. We
  • should in vain, therefore, attempt to demonstrate its falsehood. Were it
  • demonstratively false, it would imply a contradiction, and could never
  • be distinctly conceived by the mind.
  • It may, therefore, be a subject worthy of curiosity, to enquire what is
  • the nature of that evidence which assures us of any real existence and
  • matter of fact, beyond the present testimony of our senses, or the
  • records of our memory. This part of philosophy, it is observable, has
  • been little cultivated, either by the ancients or moderns; and therefore
  • our doubts and errors, in the prosecution of so important an enquiry,
  • may be the more excusable; while we march through such difficult paths
  • without any guide or direction. They may even prove useful, by exciting
  • curiosity, and destroying that implicit faith and security, which is the
  • bane of all reasoning and free enquiry. The discovery of defects in the
  • common philosophy, if any such there be, will not, I presume, be a
  • discouragement, but rather an incitement, as is usual, to attempt
  • something more full and satisfactory than has yet been proposed to
  • the public.
  • 22. All reasonings concerning matter of fact seem to be founded on the
  • relation of _Cause and Effect_. By means of that relation alone we can
  • go beyond the evidence of our memory and senses. If you were to ask a
  • man, why he believes any matter of fact, which is absent; for instance,
  • that his friend is in the country, or in France; he would give you a
  • reason; and this reason would be some other fact; as a letter received
  • from him, or the knowledge of his former resolutions and promises. A man
  • finding a watch or any other machine in a desert island, would conclude
  • that there had once been men in that island. All our reasonings
  • concerning fact are of the same nature. And here it is constantly
  • supposed that there is a connexion between the present fact and that
  • which is inferred from it. Were there nothing to bind them together, the
  • inference would be entirely precarious. The hearing of an articulate
  • voice and rational discourse in the dark assures us of the presence of
  • some person: Why? because these are the effects of the human make and
  • fabric, and closely connected with it. If we anatomize all the other
  • reasonings of this nature, we shall find that they are founded on the
  • relation of cause and effect, and that this relation is either near or
  • remote, direct or collateral. Heat and light are collateral effects of
  • fire, and the one effect may justly be inferred from the other.
  • 23. If we would satisfy ourselves, therefore, concerning the nature of
  • that evidence, which assures us of matters of fact, we must enquire how
  • we arrive at the knowledge of cause and effect.
  • I shall venture to affirm, as a general proposition, which admits of no
  • exception, that the knowledge of this relation is not, in any instance,
  • attained by reasonings _a priori_; but arises entirely from experience,
  • when we find that any particular objects are constantly conjoined with
  • each other. Let an object be presented to a man of ever so strong
  • natural reason and abilities; if that object be entirely new to him, he
  • will not be able, by the most accurate examination of its sensible
  • qualities, to discover any of its causes or effects. Adam, though his
  • rational faculties be supposed, at the very first, entirely perfect,
  • could not have inferred from the fluidity and transparency of water that
  • it would suffocate him, or from the light and warmth of fire that it
  • would consume him. No object ever discovers, by the qualities which
  • appear to the senses, either the causes which produced it, or the
  • effects which will arise from it; nor can our reason, unassisted by
  • experience, ever draw any inference concerning real existence and
  • matter of fact.
  • 24. This proposition, _that causes and effects are discoverable, not by
  • reason but by experience_, will readily be admitted with regard to such
  • objects, as we remember to have once been altogether unknown to us;
  • since we must be conscious of the utter inability, which we then lay
  • under, of foretelling what would arise from them. Present two smooth
  • pieces of marble to a man who has no tincture of natural philosophy; he
  • will never discover that they will adhere together in such a manner as
  • to require great force to separate them in a direct line, while they
  • make so small a resistance to a lateral pressure. Such events, as bear
  • little analogy to the common course of nature, are also readily
  • confessed to be known only by experience; nor does any man imagine that
  • the explosion of gunpowder, or the attraction of a loadstone, could ever
  • be discovered by arguments _a priori_. In like manner, when an effect is
  • supposed to depend upon an intricate machinery or secret structure of
  • parts, we make no difficulty in attributing all our knowledge of it to
  • experience. Who will assert that he can give the ultimate reason, why
  • milk or bread is proper nourishment for a man, not for a lion or
  • a tiger?
  • But the same truth may not appear, at first sight, to have the same
  • evidence with regard to events, which have become familiar to us from
  • our first appearance in the world, which bear a close analogy to the
  • whole course of nature, and which are supposed to depend on the simple
  • qualities of objects, without any secret structure of parts. We are apt
  • to imagine that we could discover these effects by the mere operation of
  • our reason, without experience. We fancy, that were we brought on a
  • sudden into this world, we could at first have inferred that one
  • Billiard-ball would communicate motion to another upon impulse; and that
  • we needed not to have waited for the event, in order to pronounce with
  • certainty concerning it. Such is the influence of custom, that, where it
  • is strongest, it not only covers our natural ignorance, but even
  • conceals itself, and seems not to take place, merely because it is found
  • in the highest degree.
  • 25. But to convince us that all the laws of nature, and all the
  • operations of bodies without exception, are known only by experience,
  • the following reflections may, perhaps, suffice. Were any object
  • presented to us, and were we required to pronounce concerning the
  • effect, which will result from it, without consulting past observation;
  • after what manner, I beseech you, must the mind proceed in this
  • operation? It must invent or imagine some event, which it ascribes to
  • the object as its effect; and it is plain that this invention must be
  • entirely arbitrary. The mind can never possibly find the effect in the
  • supposed cause, by the most accurate scrutiny and examination. For the
  • effect is totally different from the cause, and consequently can never
  • be discovered in it. Motion in the second Billiard-ball is a quite
  • distinct event from motion in the first; nor is there anything in the
  • one to suggest the smallest hint of the other. A stone or piece of metal
  • raised into the air, and left without any support, immediately falls:
  • but to consider the matter _a priori_, is there anything we discover in
  • this situation which can beget the idea of a downward, rather than an
  • upward, or any other motion, in the stone or metal? And as the first
  • imagination or invention of a particular effect, in all natural
  • operations, is arbitrary, where we consult not experience; so must we
  • also esteem the supposed tie or connexion between the cause and effect,
  • which binds them together, and renders it impossible that any other
  • effect could result from the operation of that cause. When I see, for
  • instance, a Billiard-ball moving in a straight line towards another;
  • even suppose motion in the second ball should by accident be suggested
  • to me, as the result of their contact or impulse; may I not conceive,
  • that a hundred different events might as well follow from that cause?
  • May not both these balls remain at absolute rest? May not the first ball
  • return in a straight line, or leap off from the second in any line or
  • direction? All these suppositions are consistent and conceivable. Why
  • then should we give the preference to one, which is no more consistent
  • or conceivable than the rest? All our reasonings _a priori_ will never
  • be able to show us any foundation for this preference.
  • In a word, then, every effect is a distinct event from its cause. It
  • could not, therefore, be discovered in the cause, and the first
  • invention or conception of it, _a priori_, must be entirely arbitrary.
  • And even after it is suggested, the conjunction of it with the cause
  • must appear equally arbitrary; since there are always many other
  • effects, which, to reason, must seem fully as consistent and natural. In
  • vain, therefore, should we pretend to determine any single event, or
  • infer any cause or effect, without the assistance of observation and
  • experience.
  • 26. Hence we may discover the reason why no philosopher, who is rational
  • and modest, has ever pretended to assign the ultimate cause of any
  • natural operation, or to show distinctly the action of that power, which
  • produces any single effect in the universe. It is confessed, that the
  • utmost effort of human reason is to reduce the principles, productive of
  • natural phenomena, to a greater simplicity, and to resolve the many
  • particular effects into a few general causes, by means of reasonings
  • from analogy, experience, and observation. But as to the causes of these
  • general causes, we should in vain attempt their discovery; nor shall we
  • ever be able to satisfy ourselves, by any particular explication of
  • them. These ultimate springs and principles are totally shut up from
  • human curiosity and enquiry. Elasticity, gravity, cohesion of parts,
  • communication of motion by impulse; these are probably the ultimate
  • causes and principles which we shall ever discover in nature; and we may
  • esteem ourselves sufficiently happy, if, by accurate enquiry and
  • reasoning, we can trace up the particular phenomena to, or near to,
  • these general principles. The most perfect philosophy of the natural
  • kind only staves off our ignorance a little longer: as perhaps the most
  • perfect philosophy of the moral or metaphysical kind serves only to
  • discover larger portions of it. Thus the observation of human blindness
  • and weakness is the result of all philosophy, and meets us at every
  • turn, in spite of our endeavours to elude or avoid it.
  • 27. Nor is geometry, when taken into the assistance of natural
  • philosophy, ever able to remedy this defect, or lead us into the
  • knowledge of ultimate causes, by all that accuracy of reasoning for
  • which it is so justly celebrated. Every part of mixed mathematics
  • proceeds upon the supposition that certain laws are established by
  • nature in her operations; and abstract reasonings are employed, either
  • to assist experience in the discovery of these laws, or to determine
  • their influence in particular instances, where it depends upon any
  • precise degree of distance and quantity. Thus, it is a law of motion,
  • discovered by experience, that the moment or force of any body in motion
  • is in the compound ratio or proportion of its solid contents and its
  • velocity; and consequently, that a small force may remove the greatest
  • obstacle or raise the greatest weight, if, by any contrivance or
  • machinery, we can increase the velocity of that force, so as to make it
  • an overmatch for its antagonist. Geometry assists us in the application
  • of this law, by giving us the just dimensions of all the parts and
  • figures which can enter into any species of machine; but still the
  • discovery of the law itself is owing merely to experience, and all the
  • abstract reasonings in the world could never lead us one step towards
  • the knowledge of it. When we reason _a priori_, and consider merely any
  • object or cause, as it appears to the mind, independent of all
  • observation, it never could suggest to us the notion of any distinct
  • object, such as its effect; much less, show us the inseparable and
  • inviolable connexion between them. A man must be very sagacious who
  • could discover by reasoning that crystal is the effect of heat, and ice
  • of cold, without being previously acquainted with the operation of these
  • qualities.
  • PART II.
  • 28. But we have not yet attained any tolerable satisfaction with regard
  • to the question first proposed. Each solution still gives rise to a new
  • question as difficult as the foregoing, and leads us on to farther
  • enquiries. When it is asked, _What is the nature of all our reasonings
  • concerning matter of fact?_ the proper answer seems to be, that they are
  • founded on the relation of cause and effect. When again it is asked,
  • _What is the foundation of all our reasonings and conclusions concerning
  • that relation?_ it may be replied in one word, Experience. But if we
  • still carry on our sifting humour, and ask, _What is the foundation of
  • all conclusions from experience?_ this implies a new question, which may
  • be of more difficult solution and explication. Philosophers, that give
  • themselves airs of superior wisdom and sufficiency, have a hard task
  • when they encounter persons of inquisitive dispositions, who push them
  • from every corner to which they retreat, and who are sure at last to
  • bring them to some dangerous dilemma. The best expedient to prevent this
  • confusion, is to be modest in our pretensions; and even to discover the
  • difficulty ourselves before it is objected to us. By this means, we may
  • make a kind of merit of our very ignorance.
  • I shall content myself, in this section, with an easy task, and shall
  • pretend only to give a negative answer to the question here proposed. I
  • say then, that, even after we have experience of the operations of cause
  • and effect, our conclusions from that experience are _not_ founded on
  • reasoning, or any process of the understanding. This answer we must
  • endeavour both to explain and to defend.
  • 29. It must certainly be allowed, that nature has kept us at a great
  • distance from all her secrets, and has afforded us only the knowledge of
  • a few superficial qualities of objects; while she conceals from us those
  • powers and principles on which the influence of those objects entirely
  • depends. Our senses inform us of the colour, weight, and consistence of
  • bread; but neither sense nor reason can ever inform us of those
  • qualities which fit it for the nourishment and support of a human body.
  • Sight or feeling conveys an idea of the actual motion of bodies; but as
  • to that wonderful force or power, which would carry on a moving body for
  • ever in a continued change of place, and which bodies never lose but by
  • communicating it to others; of this we cannot form the most distant
  • conception. But notwithstanding this ignorance of natural powers[6] and
  • principles, we always presume, when we see like sensible qualities, that
  • they have like secret powers, and expect that effects, similar to those
  • which we have experienced, will follow from them. If a body of like
  • colour and consistence with that bread, which we have formerly eat, be
  • presented to us, we make no scruple of repeating the experiment, and
  • foresee, with certainty, like nourishment and support. Now this is a
  • process of the mind or thought, of which I would willingly know the
  • foundation. It is allowed on all hands that there is no known connexion
  • between the sensible qualities and the secret powers; and consequently,
  • that the mind is not led to form such a conclusion concerning their
  • constant and regular conjunction, by anything which it knows of their
  • nature. As to past _Experience_, it can be allowed to give _direct_ and
  • _certain_ information of those precise objects only, and that precise
  • period of time, which fell under its cognizance: but why this experience
  • should be extended to future times, and to other objects, which for
  • aught we know, may be only in appearance similar; this is the main
  • question on which I would insist. The bread, which I formerly eat,
  • nourished me; that is, a body of such sensible qualities was, at that
  • time, endued with such secret powers: but does it follow, that other
  • bread must also nourish me at another time, and that like sensible
  • qualities must always be attended with like secret powers? The
  • consequence seems nowise necessary. At least, it must be acknowledged
  • that there is here a consequence drawn by the mind; that there is a
  • certain step taken; a process of thought, and an inference, which wants
  • to be explained. These two propositions are far from being the same, _I
  • have found that such an object has always been attended with such an
  • effect_, and _I foresee, that other objects, which are, in appearance,
  • similar, will be attended with similar effects_. I shall allow, if you
  • please, that the one proposition may justly be inferred from the other:
  • I know, in fact, that it always is inferred. But if you insist that the
  • inference is made by a chain of reasoning, I desire you to produce that
  • reasoning. The connexion between these propositions is not intuitive.
  • There is required a medium, which may enable the mind to draw such an
  • inference, if indeed it be drawn by reasoning and argument. What that
  • medium is, I must confess, passes my comprehension; and it is incumbent
  • on those to produce it, who assert that it really exists, and is the
  • origin of all our conclusions concerning matter of fact.
  • [6] The word, Power, is here used in a loose and popular sense.
  • The more accurate explication of it would give additional
  • evidence to this argument. See Sect. 7.
  • 30. This negative argument must certainly, in process of time, become
  • altogether convincing, if many penetrating and able philosophers shall
  • turn their enquiries this way and no one be ever able to discover any
  • connecting proposition or intermediate step, which supports the
  • understanding in this conclusion. But as the question is yet new, every
  • reader may not trust so far to his own penetration, as to conclude,
  • because an argument escapes his enquiry, that therefore it does not
  • really exist. For this reason it may be requisite to venture upon a more
  • difficult task; and enumerating all the branches of human knowledge,
  • endeavour to show that none of them can afford such an argument.
  • All reasonings may be divided into two kinds, namely, demonstrative
  • reasoning, or that concerning relations of ideas, and moral reasoning,
  • or that concerning matter of fact and existence. That there are no
  • demonstrative arguments in the case seems evident; since it implies no
  • contradiction that the course of nature may change, and that an object,
  • seemingly like those which we have experienced, may be attended with
  • different or contrary effects. May I not clearly and distinctly conceive
  • that a body, falling from the clouds, and which, in all other respects,
  • resembles snow, has yet the taste of salt or feeling of fire? Is there
  • any more intelligible proposition than to affirm, that all the trees
  • will flourish in December and January, and decay in May and June? Now
  • whatever is intelligible, and can be distinctly conceived, implies no
  • contradiction, and can never be proved false by any demonstrative
  • argument or abstract reasoning _à priori_.
  • If we be, therefore, engaged by arguments to put trust in past
  • experience, and make it the standard of our future judgement, these
  • arguments must be probable only, or such as regard matter of fact and
  • real existence, according to the division above mentioned. But that
  • there is no argument of this kind, must appear, if our explication of
  • that species of reasoning be admitted as solid and satisfactory. We have
  • said that all arguments concerning existence are founded on the relation
  • of cause and effect; that our knowledge of that relation is derived
  • entirely from experience; and that all our experimental conclusions
  • proceed upon the supposition that the future will be conformable to the
  • past. To endeavour, therefore, the proof of this last supposition by
  • probable arguments, or arguments regarding existence, must be evidently
  • going in a circle, and taking that for granted, which is the very point
  • in question.
  • 31. In reality, all arguments from experience are founded on the
  • similarity which we discover among natural objects, and by which we are
  • induced to expect effects similar to those which we have found to follow
  • from such objects. And though none but a fool or madman will ever
  • pretend to dispute the authority of experience, or to reject that great
  • guide of human life, it may surely be allowed a philosopher to have so
  • much curiosity at least as to examine the principle of human nature,
  • which gives this mighty authority to experience, and makes us draw
  • advantage from that similarity which nature has placed among different
  • objects. From causes which appear _similar_ we expect similar effects.
  • This is the sum of all our experimental conclusions. Now it seems
  • evident that, if this conclusion were formed by reason, it would be as
  • perfect at first, and upon one instance, as after ever so long a course
  • of experience. But the case is far otherwise. Nothing so like as eggs;
  • yet no one, on account of this appearing similarity, expects the same
  • taste and relish in all of them. It is only after a long course of
  • uniform experiments in any kind, that we attain a firm reliance and
  • security with regard to a particular event. Now where is that process of
  • reasoning which, from one instance, draws a conclusion, so different
  • from that which it infers from a hundred instances that are nowise
  • different from that single one? This question I propose as much for the
  • sake of information, as with an intention of raising difficulties. I
  • cannot find, I cannot imagine any such reasoning. But I keep my mind
  • still open to instruction, if any one will vouchsafe to bestow it on me.
  • 32. Should it be said that, from a number of uniform experiments, we
  • _infer_ a connexion between the sensible qualities and the secret
  • powers; this, I must confess, seems the same difficulty, couched in
  • different terms. The question still recurs, on what process of argument
  • this _inference_ is founded? Where is the medium, the interposing ideas,
  • which join propositions so very wide of each other? It is confessed that
  • the colour, consistence, and other sensible qualities of bread appear
  • not, of themselves, to have any connexion with the secret powers of
  • nourishment and support. For otherwise we could infer these secret
  • powers from the first appearance of these sensible qualities, without
  • the aid of experience; contrary to the sentiment of all philosophers,
  • and contrary to plain matter of fact. Here, then, is our natural state
  • of ignorance with regard to the powers and influence of all objects. How
  • is this remedied by experience? It only shows us a number of uniform
  • effects, resulting from certain objects, and teaches us that those
  • particular objects, at that particular time, were endowed with such
  • powers and forces. When a new object, endowed with similar sensible
  • qualities, is produced, we expect similar powers and forces, and look
  • for a like effect. From a body of like colour and consistence with bread
  • we expect like nourishment and support. But this surely is a step or
  • progress of the mind, which wants to be explained. When a man says, _I
  • have found, in all past instances, such sensible qualities conjoined
  • with such secret powers_: And when he says, _Similar sensible qualities
  • will always be conjoined with similar secret powers_, he is not guilty
  • of a tautology, nor are these propositions in any respect the same. You
  • say that the one proposition is an inference from the other. But you
  • must confess that the inference is not intuitive; neither is it
  • demonstrative: Of what nature is it, then? To say it is experimental, is
  • begging the question. For all inferences from experience suppose, as
  • their foundation, that the future will resemble the past, and that
  • similar powers will be conjoined with similar sensible qualities. If
  • there be any suspicion that the course of nature may change, and that
  • the past may be no rule for the future, all experience becomes useless,
  • and can give rise to no inference or conclusion. It is impossible,
  • therefore, that any arguments from experience can prove this resemblance
  • of the past to the future; since all these arguments are founded on the
  • supposition of that resemblance. Let the course of things be allowed
  • hitherto ever so regular; that alone, without some new argument or
  • inference, proves not that, for the future, it will continue so. In vain
  • do you pretend to have learned the nature of bodies from your past
  • experience. Their secret nature, and consequently all their effects and
  • influence, may change, without any change in their sensible qualities.
  • This happens sometimes, and with regard to some objects: Why may it not
  • happen always, and with regard to all objects? What logic, what process
  • of argument secures you against this supposition? My practice, you say,
  • refutes my doubts. But you mistake the purport of my question. As an
  • agent, I am quite satisfied in the point; but as a philosopher, who has
  • some share of curiosity, I will not say scepticism, I want to learn the
  • foundation of this inference. No reading, no enquiry has yet been able
  • to remove my difficulty, or give me satisfaction in a matter of such
  • importance. Can I do better than propose the difficulty to the public,
  • even though, perhaps, I have small hopes of obtaining a solution? We
  • shall at least, by this means, be sensible of our ignorance, if we do
  • not augment our knowledge.
  • 33. I must confess that a man is guilty of unpardonable arrogance who
  • concludes, because an argument has escaped his own investigation, that
  • therefore it does not really exist. I must also confess that, though all
  • the learned, for several ages, should have employed themselves in
  • fruitless search upon any subject, it may still, perhaps, be rash to
  • conclude positively that the subject must, therefore, pass all human
  • comprehension. Even though we examine all the sources of our knowledge,
  • and conclude them unfit for such a subject, there may still remain a
  • suspicion, that the enumeration is not complete, or the examination not
  • accurate. But with regard to the present subject, there are some
  • considerations which seem to remove all this accusation of arrogance or
  • suspicion of mistake.
  • It is certain that the most ignorant and stupid peasants--nay infants,
  • nay even brute beasts--improve by experience, and learn the qualities of
  • natural objects, by observing the effects which result from them. When a
  • child has felt the sensation of pain from touching the flame of a
  • candle, he will be careful not to put his hand near any candle; but will
  • expect a similar effect from a cause which is similar in its sensible
  • qualities and appearance. If you assert, therefore, that the
  • understanding of the child is led into this conclusion by any process of
  • argument or ratiocination, I may justly require you to produce that
  • argument; nor have you any pretence to refuse so equitable a demand. You
  • cannot say that the argument is abstruse, and may possibly escape your
  • enquiry; since you confess that it is obvious to the capacity of a mere
  • infant. If you hesitate, therefore, a moment, or if, after reflection,
  • you produce any intricate or profound argument, you, in a manner, give
  • up the question, and confess that it is not reasoning which engages us
  • to suppose the past resembling the future, and to expect similar effects
  • from causes which are, to appearance, similar. This is the proposition
  • which I intended to enforce in the present section. If I be right, I
  • pretend not to have made any mighty discovery. And if I be wrong, I must
  • acknowledge myself to be indeed a very backward scholar; since I cannot
  • now discover an argument which, it seems, was perfectly familiar to me
  • long before I was out of my cradle.
  • SECTION V.
  • SCEPTICAL SOLUTION OF THESE DOUBTS.
  • PART I.
  • 34. The passion for philosophy, like that for religion, seems liable to
  • this inconvenience, that, though it aims at the correction of our
  • manners, and extirpation of our vices, it may only serve, by imprudent
  • management, to foster a predominant inclination, and push the mind, with
  • more determined resolution, towards that side which already _draws_ too
  • much, by the bias and propensity of the natural temper. It is certain
  • that, while we aspire to the magnanimous firmness of the philosophic
  • sage, and endeavour to confine our pleasures altogether within our own
  • minds, we may, at last, render our philosophy like that of Epictetus,
  • and other _Stoics_, only a more refined system of selfishness, and
  • reason ourselves out of all virtue as well as social enjoyment. While we
  • study with attention the vanity of human life, and turn all our thoughts
  • towards the empty and transitory nature of riches and honours, we are,
  • perhaps, all the while flattering our natural indolence, which, hating
  • the bustle of the world, and drudgery of business, seeks a pretence of
  • reason to give itself a full and uncontrolled indulgence. There is,
  • however, one species of philosophy which seems little liable to this
  • inconvenience, and that because it strikes in with no disorderly passion
  • of the human mind, nor can mingle itself with any natural affection or
  • propensity; and that is the Academic or Sceptical philosophy. The
  • academics always talk of doubt and suspense of judgement, of danger in
  • hasty determinations, of confining to very narrow bounds the enquiries
  • of the understanding, and of renouncing all speculations which lie not
  • within the limits of common life and practice. Nothing, therefore, can
  • be more contrary than such a philosophy to the supine indolence of the
  • mind, its rash arrogance, its lofty pretensions, and its superstitious
  • credulity. Every passion is mortified by it, except the love of truth;
  • and that passion never is, nor can be, carried to too high a degree. It
  • is surprising, therefore, that this philosophy, which, in almost every
  • instance, must be harmless and innocent, should be the subject of so
  • much groundless reproach and obloquy. But, perhaps, the very
  • circumstance which renders it so innocent is what chiefly exposes it to
  • the public hatred and resentment. By flattering no irregular passion, it
  • gains few partizans: By opposing so many vices and follies, it raises to
  • itself abundance of enemies, who stigmatize it as libertine profane, and
  • irreligious.
  • Nor need we fear that this philosophy, while it endeavours to limit our
  • enquiries to common life, should ever undermine the reasonings of common
  • life, and carry its doubts so far as to destroy all action, as well as
  • speculation. Nature will always maintain her rights, and prevail in the
  • end over any abstract reasoning whatsoever. Though we should conclude,
  • for instance, as in the foregoing section, that, in all reasonings from
  • experience, there is a step taken by the mind which is not supported by
  • any argument or process of the understanding; there is no danger that
  • these reasonings, on which almost all knowledge depends, will ever be
  • affected by such a discovery. If the mind be not engaged by argument to
  • make this step, it must be induced by some other principle of equal
  • weight and authority; and that principle will preserve its influence as
  • long as human nature remains the same. What that principle is may well
  • be worth the pains of enquiry.
  • 35. Suppose a person, though endowed with the strongest faculties of
  • reason and reflection, to be brought on a sudden into this world; he
  • would, indeed, immediately observe a continual succession of objects,
  • and one event following another; but he would not be able to discover
  • anything farther. He would not, at first, by any reasoning, be able to
  • reach the idea of cause and effect; since the particular powers, by
  • which all natural operations are performed, never appear to the senses;
  • nor is it reasonable to conclude, merely because one event, in one
  • instance, precedes another, that therefore the one is the cause, the
  • other the effect. Their conjunction may be arbitrary and casual. There
  • may be no reason to infer the existence of one from the appearance of
  • the other. And in a word, such a person, without more experience, could
  • never employ his conjecture or reasoning concerning any matter of fact,
  • or be assured of anything beyond what was immediately present to his
  • memory and senses.
  • Suppose, again, that he has acquired more experience, and has lived so
  • long in the world as to have observed familiar objects or events to be
  • constantly conjoined together; what is the consequence of this
  • experience? He immediately infers the existence of one object from the
  • appearance of the other. Yet he has not, by all his experience, acquired
  • any idea or knowledge of the secret power by which the one object
  • produces the other; nor is it, by any process of reasoning, he is
  • engaged to draw this inference. But still he finds himself determined to
  • draw it: And though he should be convinced that his understanding has no
  • part in the operation, he would nevertheless continue in the same course
  • of thinking. There is some other principle which determines him to form
  • such a conclusion.
  • 36. This principle is Custom or Habit. For wherever the repetition of
  • any particular act or operation produces a propensity to renew the same
  • act or operation, without being impelled by any reasoning or process of
  • the understanding, we always say, that this propensity is the effect of
  • _Custom_. By employing that word, we pretend not to have given the
  • ultimate reason of such a propensity. We only point out a principle of
  • human nature, which is universally acknowledged, and which is well known
  • by its effects. Perhaps we can push our enquiries no farther, or pretend
  • to give the cause of this cause; but must rest contented with it as the
  • ultimate principle, which we can assign, of all our conclusions from
  • experience. It is sufficient satisfaction, that we can go so far,
  • without repining at the narrowness of our faculties because they will
  • carry us no farther. And it is certain we here advance a very
  • intelligible proposition at least, if not a true one, when we assert
  • that, after the constant conjunction of two objects--heat and flame, for
  • instance, weight and solidity--we are determined by custom alone to
  • expect the one from the appearance of the other. This hypothesis seems
  • even the only one which explains the difficulty, why we draw, from a
  • thousand instances, an inference which we are not able to draw from one
  • instance, that is, in no respect, different from them. Reason is
  • incapable of any such variation. The conclusions which it draws from
  • considering one circle are the same which it would form upon surveying
  • all the circles in the universe. But no man, having seen only one body
  • move after being impelled by another, could infer that every other body
  • will move after a like impulse. All inferences from experience,
  • therefore, are effects of custom, not of reasoning[7].
  • [7] Nothing is more useful than for writers, even, on _moral_,
  • _political_, or _physical_ subjects, to distinguish between
  • _reason_ and _experience_, and to suppose, that these species
  • of argumentation are entirely different from each other. The
  • former are taken for the mere result of our intellectual
  • faculties, which, by considering _à priori_ the nature of
  • things, and examining the effects, that must follow from their
  • operation, establish particular principles of science and
  • philosophy. The latter are supposed to be derived entirely from
  • sense and observation, by which we learn what has actually
  • resulted from the operation of particular objects, and are
  • thence able to infer, what will, for the future, result from
  • them. Thus, for instance, the limitations and restraints of
  • civil government, and a legal constitution, may be defended,
  • either from _reason_, which reflecting on the great frailty and
  • corruption of human nature, teaches, that no man can safely be
  • trusted with unlimited authority; or from _experience_ and
  • history, which inform us of the enormous abuses, that ambition,
  • in every age and country, has been found to make of so
  • imprudent a confidence.
  • The same distinction between reason and experience is
  • maintained in all our deliberations concerning the conduct of
  • life; while the experienced statesman, general, physician, or
  • merchant is trusted and followed; and the unpractised novice,
  • with whatever natural talents endowed, neglected and despised.
  • Though it be allowed, that reason may form very plausible
  • conjectures with regard to the consequences of such a
  • particular conduct in such particular circumstances; it is
  • still supposed imperfect, without the assistance of experience,
  • which is alone able to give stability and certainty to the
  • maxims, derived from study and reflection.
  • But notwithstanding that this distinction be thus universally
  • received, both in the active speculative scenes of life, I
  • shall not scruple to pronounce, that it is, at bottom,
  • erroneous, at least, superficial.
  • If we examine those arguments, which, in any of the sciences
  • above mentioned, are supposed to be the mere effects of
  • reasoning and reflection, they will be found to terminate, at
  • last, in some general principle or conclusion, for which we can
  • assign no reason but observation and experience. The only
  • difference between them and those maxims, which are vulgarly
  • esteemed the result of pure experience, is, that the former
  • cannot be established without some process of thought, and some
  • reflection on what we have observed, in order to distinguish
  • its circumstances, and trace its consequences: Whereas in the
  • latter, the experienced event is exactly and fully familiar to
  • that which we infer as the result of any particular situation.
  • The history of a TIBERIUS or a NERO makes us dread a like
  • tyranny, were our monarchs freed from the restraints of laws
  • and senates: But the observation of any fraud or cruelty in
  • private life is sufficient, with the aid of a little thought,
  • to give us the same apprehension; while it serves as an
  • instance of the general corruption of human nature, and shows
  • us the danger which we must incur by reposing an entire
  • confidence in mankind. In both cases, it is experience which is
  • ultimately the foundation of our inference and conclusion.
  • There is no man so young and unexperienced, as not to have
  • formed, from observation, many general and just maxims
  • concerning human affairs and the conduct of life; but it must
  • be confessed, that, when a man comes to put these in practice,
  • he will be extremely liable to error, till time and farther
  • experience both enlarge these maxims, and teach him their
  • proper use and application. In every situation or incident,
  • there are many particular and seemingly minute circumstances,
  • which the man of greatest talent is, at first, apt to overlook,
  • though on them the justness of his conclusions, and
  • consequently the prudence of his conduct, entirely depend. Not
  • to mention, that, to a young beginner, the general observations
  • and maxims occur not always on the proper occasions, nor can be
  • immediately applied with due calmness and distinction. The
  • truth is, an unexperienced reasoner could be no reasoner at
  • all, were he absolutely unexperienced; and when we assign that
  • character to any one, we mean it only in a comparative sense,
  • and suppose him possessed of experience, in a smaller and more
  • imperfect degree.
  • Custom, then, is the great guide of human life. It is that principle
  • alone which renders our experience useful to us, and makes us expect,
  • for the future, a similar train of events with those which have appeared
  • in the past.
  • Without the influence of custom, we should be entirely ignorant of every
  • matter of fact beyond what is immediately present to the memory and
  • senses. We should never know how to adjust means to ends, or to employ
  • our natural powers in the production of any effect. There would be an
  • end at once of all action, as well as of the chief part of speculation.
  • 37. But here it may be proper to remark, that though our conclusions
  • from experience carry us beyond our memory and senses, and assure us of
  • matters of fact which happened in the most distant places and most
  • remote ages, yet some fact must always be present to the senses or
  • memory, from which we may first proceed in drawing these conclusions. A
  • man, who should find in a desert country the remains of pompous
  • buildings, would conclude that the country had, in ancient times, been
  • cultivated by civilized inhabitants; but did nothing of this nature
  • occur to him, he could never form such an inference. We learn the events
  • of former ages from history; but then we must peruse the volumes in
  • which this instruction is contained, and thence carry up our inferences
  • from one testimony to another, till we arrive at the eyewitnesses and
  • spectators of these distant events. In a word, if we proceed not upon
  • some fact, present to the memory or senses, our reasonings would be
  • merely hypothetical; and however the particular links might be connected
  • with each other, the whole chain of inferences would have nothing to
  • support it, nor could we ever, by its means, arrive at the knowledge of
  • any real existence. If I ask why you believe any particular matter of
  • fact, which you relate, you must tell me some reason; and this reason
  • will be some other fact, connected with it. But as you cannot proceed
  • after this manner, _in infinitum_, you must at last terminate in some
  • fact, which is present to your memory or senses; or must allow that your
  • belief is entirely without foundation.
  • 38. What, then, is the conclusion of the whole matter? A simple one;
  • though, it must be confessed, pretty remote from the common theories of
  • philosophy. All belief of matter of fact or real existence is derived
  • merely from some object, present to the memory or senses, and a
  • customary conjunction between that and some other object. Or in other
  • words; having found, in many instances, that any two kinds of
  • objects--flame and heat, snow and cold--have always been conjoined
  • together; if flame or snow be presented anew to the senses, the mind is
  • carried by custom to expect heat or cold, and to _believe_ that such a
  • quality does exist, and will discover itself upon a nearer approach.
  • This belief is the necessary result of placing the mind in such
  • circumstances. It is an operation of the soul, when we are so situated,
  • as unavoidable as to feel the passion of love, when we receive benefits;
  • or hatred, when we meet with injuries. All these operations are a
  • species of natural instincts, which no reasoning or process of the
  • thought and understanding is able either to produce or to prevent.
  • At this point, it would be very allowable for us to stop our
  • philosophical researches. In most questions we can never make a single
  • step farther; and in all questions we must terminate here at last, after
  • our most restless and curious enquiries. But still our curiosity will be
  • pardonable, perhaps commendable, if it carry us on to still farther
  • researches, and make us examine more accurately the nature of this
  • _belief_, and of the _customary conjunction_, whence it is derived. By
  • this means we may meet with some explications and analogies that will
  • give satisfaction; at least to such as love the abstract sciences, and
  • can be entertained with speculations, which, however accurate, may still
  • retain a degree of doubt and uncertainty. As to readers of a different
  • taste; the remaining part of this section is not calculated for them,
  • and the following enquiries may well be understood, though it be
  • neglected.
  • PART II.
  • 39. Nothing is more free than the imagination of man; and though it
  • cannot exceed that original stock of ideas furnished by the internal and
  • external senses, it has unlimited power of mixing, compounding,
  • separating, and dividing these ideas, in all the varieties of fiction
  • and vision. It can feign a train of events, with all the appearance of
  • reality, ascribe to them a particular time and place, conceive them as
  • existent, and paint them out to itself with every circumstance, that
  • belongs to any historical fact, which it believes with the greatest
  • certainty. Wherein, therefore, consists the difference between such a
  • fiction and belief? It lies not merely in any peculiar idea, which is
  • annexed to such a conception as commands our assent, and which is
  • wanting to every known fiction. For as the mind has authority over all
  • its ideas, it could voluntarily annex this particular idea to any
  • fiction, and consequently be able to believe whatever it pleases;
  • contrary to what we find by daily experience. We can, in our conception,
  • join the head of a man to the body of a horse; but it is not in our
  • power to believe that such an animal has ever really existed.
  • It follows, therefore, that the difference between _fiction_ and
  • _belief_ lies in some sentiment or feeling, which is annexed to the
  • latter, not to the former, and which depends not on the will, nor can be
  • commanded at pleasure. It must be excited by nature, like all other
  • sentiments; and must arise from the particular situation, in which the
  • mind is placed at any particular juncture. Whenever any object is
  • presented to the memory or senses, it immediately, by the force of
  • custom, carries the imagination to conceive that object, which is
  • usually conjoined to it; and this conception is attended with a feeling
  • or sentiment, different from the loose reveries of the fancy. In this
  • consists the whole nature of belief. For as there is no matter of fact
  • which we believe so firmly that we cannot conceive the contrary, there
  • would be no difference between the conception assented to and that which
  • is rejected, were it not for some sentiment which distinguishes the one
  • from the other. If I see a billiard-ball moving towards another, on a
  • smooth table, I can easily conceive it to stop upon contact. This
  • conception implies no contradiction; but still it feels very differently
  • from that conception by which I represent to myself the impulse and the
  • communication of motion from one ball to another.
  • 40. Were we to attempt a _definition_ of this sentiment, we should,
  • perhaps, find it a very difficult, if not an impossible task; in the
  • same manner as if we should endeavour to define the feeling of cold or
  • passion of anger, to a creature who never had any experience of these
  • sentiments. Belief is the true and proper name of this feeling; and no
  • one is ever at a loss to know the meaning of that term; because every
  • man is every moment conscious of the sentiment represented by it. It may
  • not, however, be improper to attempt a _description_ of this sentiment;
  • in hopes we may, by that means, arrive at some analogies, which may
  • afford a more perfect explication of it. I say, then, that belief is
  • nothing but a more vivid, lively, forcible, firm, steady conception of
  • an object, than what the imagination alone is ever able to attain. This
  • variety of terms, which may seem so unphilosophical, is intended only to
  • express that act of the mind, which renders realities, or what is taken
  • for such, more present to us than fictions, causes them to weigh more in
  • the thought, and gives them a superior influence on the passions and
  • imagination. Provided we agree about the thing, it is needless to
  • dispute about the terms. The imagination has the command over all its
  • ideas, and can join and mix and vary them, in all the ways possible. It
  • may conceive fictitious objects with all the circumstances of place and
  • time. It may set them, in a manner, before our eyes, in their true
  • colours, just as they might have existed. But as it is impossible that
  • this faculty of imagination can ever, of itself, reach belief, it is
  • evident that belief consists not in the peculiar nature or order of
  • ideas, but in the _manner_ of their conception, and in their _feeling_
  • to the mind. I confess, that it is impossible perfectly to explain this
  • feeling or manner of conception. We may make use of words which express
  • something near it. But its true and proper name, as we observed before,
  • is _belief_; which is a term that every one sufficiently understands in
  • common life. And in philosophy, we can go no farther than assert, that
  • _belief_ is something felt by the mind, which distinguishes the ideas of
  • the judgement from the fictions of the imagination. It gives them more
  • weight and influence; makes them appear of greater importance; enforces
  • them in the mind; and renders them the governing principle of our
  • actions. I hear at present, for instance, a person's voice, with whom I
  • am acquainted; and the sound comes as from the next room. This
  • impression of my senses immediately conveys my thought to the person,
  • together with all the surrounding objects. I paint them out to myself as
  • existing at present, with the same qualities and relations, of which I
  • formerly knew them possessed. These ideas take faster hold of my mind
  • than ideas of an enchanted castle. They are very different to the
  • feeling, and have a much greater influence of every kind, either to give
  • pleasure or pain, joy or sorrow.
  • Let us, then, take in the whole compass of this doctrine, and allow,
  • that the sentiment of belief is nothing but a conception more intense
  • and steady than what attends the mere fictions of the imagination, and
  • that this _manner_ of conception arises from a customary conjunction of
  • the object with something present to the memory or senses: I believe
  • that it will not be difficult, upon these suppositions, to find other
  • operations of the mind analogous to it, and to trace up these phenomena
  • to principles still more general.
  • 41. We have already observed that nature has established connexions
  • among particular ideas, and that no sooner one idea occurs to our
  • thoughts than it introduces its correlative, and carries our attention
  • towards it, by a gentle and insensible movement. These principles of
  • connexion or association we have reduced to three, namely,
  • _Resemblance_, _Contiguity_ and _Causation_; which are the only bonds
  • that unite our thoughts together, and beget that regular train of
  • reflection or discourse, which, in a greater or less degree, takes place
  • among all mankind. Now here arises a question, on which the solution of
  • the present difficulty will depend. Does it happen, in all these
  • relations, that, when one of the objects is presented to the senses or
  • memory, the mind is not only carried to the conception of the
  • correlative, but reaches a steadier and stronger conception of it than
  • what otherwise it would have been able to attain? This seems to be the
  • case with that belief which arises from the relation of cause and
  • effect. And if the case be the same with the other relations or
  • principles of associations, this may be established as a general law,
  • which takes place in all the operations of the mind.
  • We may, therefore, observe, as the first experiment to our present
  • purpose, that, upon the appearance of the picture of an absent friend,
  • our idea of him is evidently enlivened by the _resemblance_, and that
  • every passion, which that idea occasions, whether of joy or sorrow,
  • acquires new force and vigour. In producing this effect, there concur
  • both a relation and a present impression. Where the picture bears him no
  • resemblance, at least was not intended for him, it never so much as
  • conveys our thought to him: And where it is absent, as well as the
  • person, though the mind may pass from the thought of the one to that of
  • the other, it feels its idea to be rather weakened than enlivened by
  • that transition. We take a pleasure in viewing the picture of a friend,
  • when it is set before us; but when it is removed, rather choose to
  • consider him directly than by reflection in an image, which is equally
  • distant and obscure.
  • The ceremonies of the Roman Catholic religion may be considered as
  • instances of the same nature. The devotees of that superstition usually
  • plead in excuse for the mummeries, with which they are upbraided, that
  • they feel the good effect of those external motions, and postures, and
  • actions, in enlivening their devotion and quickening their fervour,
  • which otherwise would decay, if directed entirely to distant and
  • immaterial objects. We shadow out the objects of our faith, say they, in
  • sensible types and images, and render them more present to us by the
  • immediate presence of these types, than it is possible for us to do
  • merely by an intellectual view and contemplation. Sensible objects have
  • always a greater influence on the fancy than any other; and this
  • influence they readily convey to those ideas to which they are related,
  • and which they resemble. I shall only infer from these practices, and
  • this reasoning, that the effect of resemblance in enlivening the ideas
  • is very common; and as in every case a resemblance and a present
  • impression must concur, we are abundantly supplied with experiments to
  • prove the reality of the foregoing principle.
  • 42. We may add force to these experiments by others of a different kind,
  • in considering the effects of _contiguity_ as well as of _resemblance_.
  • It is certain that distance diminishes the force of every idea, and
  • that, upon our approach to any object; though it does not discover
  • itself to our senses; it operates upon the mind with an influence, which
  • imitates an immediate impression. The thinking on any object readily
  • transports the mind to what is contiguous; but it is only the actual
  • presence of an object, that transports it with a superior vivacity. When
  • I am a few miles from home, whatever relates to it touches me more
  • nearly than when I am two hundred leagues distant; though even at that
  • distance the reflecting on any thing in the neighbourhood of my friends
  • or family naturally produces an idea of them. But as in this latter
  • case, both the objects of the mind are ideas; notwithstanding there is
  • an easy transition between them; that transition alone is not able to
  • give a superior vivacity to any of the ideas, for want of some immediate
  • impression[8].

  • 43. No one can doubt but causation has the same influence as the other
  • two relations of resemblance and contiguity. Superstitious people are
  • fond of the reliques of saints and holy men, for the same reason, that
  • they seek after types or images, in order to enliven their devotion, and
  • give them a more intimate and strong conception of those exemplary
  • lives, which they desire to imitate. Now it is evident, that one of the
  • best reliques, which a devotee could procure, would be the handywork of
  • a saint; and if his cloaths and furniture are ever to be considered in
  • this light, it is because they were once at his disposal, and were moved
  • and affected by him; in which respect they are to be considered as
  • imperfect effects, and as connected with him by a shorter chain of
  • consequences than any of those, by which we learn the reality of his
  • existence.
  • Suppose, that the son of a friend, who had been long dead or absent,
  • were presented to us; it is evident, that this object would instantly
  • revive its correlative idea, and recal to our thoughts all past
  • intimacies and familiarities, in more lively colours than they would
  • otherwise have appeared to us. This is another phaenomenon, which seems
  • to prove the principle above mentioned.
  • 44. We may observe, that, in these phaenomena, the belief of the
  • correlative object is always presupposed; without which the relation
  • could have no effect. The influence of the picture supposes, that we
  • _believe_ our friend to have once existed. Contiguity to home can never
  • excite our ideas of home, unless we _believe_ that it really exists. Now
  • I assert, that this belief, where it reaches beyond the memory or
  • senses, is of a similar nature, and arises from similar causes, with the
  • transition of thought and vivacity of conception here explained. When I
  • throw a piece of dry wood into a fire, my mind is immediately carried to
  • conceive, that it augments, not extinguishes the flame. This transition
  • of thought from the cause to the effect proceeds not from reason. It
  • derives its origin altogether from custom and experience. And as it
  • first begins from an object, present to the senses, it renders the idea
  • or conception of flame more strong and lively than any loose, floating
  • reverie of the imagination. That idea arises immediately. The thought
  • moves instantly towards it, and conveys to it all that force of
  • conception, which is derived from the impression present to the senses.
  • When a sword is levelled at my breast, does not the idea of wound and
  • pain strike me more strongly, than when a glass of wine is presented to
  • me, even though by accident this idea should occur after the appearance
  • of the latter object? But what is there in this whole matter to cause
  • such a strong conception, except only a present object and a customary
  • transition to the idea of another object, which we have been accustomed
  • to conjoin with the former? This is the whole operation of the mind, in
  • all our conclusions concerning matter of fact and existence; and it is a
  • satisfaction to find some analogies, by which it may be explained. The
  • transition from a present object does in all cases give strength and
  • solidity to the related idea.
  • Here, then, is a kind of pre-established harmony between the course of
  • nature and the succession of our ideas; and though the powers and
  • forces, by which the former is governed, be wholly unknown to us; yet
  • our thoughts and conceptions have still, we find, gone on in the same
  • train with the other works of nature. Custom is that principle, by which
  • this correspondence has been effected; so necessary to the subsistence
  • of our species, and the regulation of our conduct, in every circumstance
  • and occurrence of human life. Had not the presence of an object,
  • instantly excited the idea of those objects, commonly conjoined with it,
  • all our knowledge must have been limited to the narrow sphere of our
  • memory and senses; and we should never have been able to adjust means to
  • ends, or employ our natural powers, either to the producing of good, or
  • avoiding of evil. Those, who delight in the discovery and contemplation
  • of _final causes_, have here ample subject to employ their wonder and
  • admiration.
  • 45. I shall add, for a further confirmation of the foregoing theory,
  • that, as this operation of the mind, by which we infer like effects from
  • like causes, and _vice versa_, is so essential to the subsistence of all
  • human creatures, it is not probable, that it could be trusted to the
  • fallacious deductions of our reason, which is slow in its operations;
  • appears not, in any degree, during the first years of infancy; and at
  • best is, in every age and period of human life, extremely liable to
  • error and mistake. It is more conformable to the ordinary wisdom of
  • nature to secure so necessary an act of the mind, by some instinct or
  • mechanical tendency, which may be infallible in its operations, may
  • discover itself at the first appearance of life and thought, and may be
  • independent of all the laboured deductions of the understanding. As
  • nature has taught us the use of our limbs, without giving us the
  • knowledge of the muscles and nerves, by which they are actuated; so has
  • she implanted in us an instinct, which carries forward the thought in a
  • correspondent course to that which she has established among external
  • objects; though we are ignorant of those powers and forces, on which
  • this regular course and succession of objects totally depends.
  • SECTION VI.
  • OF PROBABILITY[9].
  • [9] Mr. Locke divides all arguments into demonstrative and
  • probable. In this view, we must say, that it is only probable
  • all men must die, or that the sun will rise to-morrow. But to
  • conform our language more to common use, we ought to divide
  • arguments into _demonstrations_, _proofs_, and _probabilities_.
  • By proofs meaning such arguments from experience as leave no
  • room for doubt or opposition.
  • 46. Though there be no such thing as _Chance_ in the world; our
  • ignorance of the real cause of any event has the same influence on the
  • understanding, and begets a like species of belief or opinion.
  • There is certainly a probability, which arises from a superiority of
  • chances on any side; and according as this superiority encreases, and
  • surpasses the opposite chances, the probability receives a
  • proportionable encrease, and begets still a higher degree of belief or
  • assent to that side, in which we discover the superiority. If a dye were
  • marked with one figure or number of spots on four sides, and with
  • another figure or number of spots on the two remaining sides, it would
  • be more probable, that the former would turn up than the latter; though,
  • if it had a thousand sides marked in the same manner, and only one side
  • different, the probability would be much higher, and our belief or
  • expectation of the event more steady and secure. This process of the
  • thought or reasoning may seem trivial and obvious; but to those who
  • consider it more narrowly, it may, perhaps, afford matter for curious
  • speculation.
  • It seems evident, that, when the mind looks forward to discover the
  • event, which may result from the throw of such a dye, it considers the
  • turning up of each particular side as alike probable; and this is the
  • very nature of chance, to render all the particular events, comprehended
  • in it, entirely equal. But finding a greater number of sides concur in
  • the one event than in the other, the mind is carried more frequently to
  • that event, and meets it oftener, in revolving the various possibilities
  • or chances, on which the ultimate result depends. This concurrence of
  • several views in one particular event begets immediately, by an
  • inexplicable contrivance of nature, the sentiment of belief, and gives
  • that event the advantage over its antagonist, which is supported by a
  • smaller number of views, and recurs less frequently to the mind. If we
  • allow, that belief is nothing but a firmer and stronger conception of an
  • object than what attends the mere fictions of the imagination, this
  • operation may, perhaps, in some measure, be accounted for. The
  • concurrence of these several views or glimpses imprints the idea more
  • strongly on the imagination; gives it superior force and vigour; renders
  • its influence on the passions and affections more sensible; and in a
  • word, begets that reliance or security, which constitutes the nature of
  • belief and opinion.
  • 47. The case is the same with the probability of causes, as with that of
  • chance. There are some causes, which are entirely uniform and constant
  • in producing a particular effect; and no instance has ever yet been
  • found of any failure or irregularity in their operation. Fire has always
  • burned, and water suffocated every human creature: The production of
  • motion by impulse and gravity is an universal law, which has hitherto
  • admitted of no exception. But there are other causes, which have been
  • found more irregular and uncertain; nor has rhubarb always proved a
  • purge, or opium a soporific to every one, who has taken these medicines.
  • It is true, when any cause fails of producing its usual effect,
  • philosophers ascribe not this to any irregularity in nature; but
  • suppose, that some secret causes, in the particular structure of parts,
  • have prevented the operation. Our reasonings, however, and conclusions
  • concerning the event are the same as if this principle had no place.
  • Being determined by custom to transfer the past to the future, in all
  • our inferences; where the past has been entirely regular and uniform, we
  • expect the event with the greatest assurance, and leave no room for any
  • contrary supposition. But where different effects have been found to
  • follow from causes, which are to _appearance_ exactly similar, all these
  • various effects must occur to the mind in transferring the past to the
  • future, and enter into our consideration, when we determine the
  • probability of the event. Though we give the preference to that which
  • has been found most usual, and believe that this effect will exist, we
  • must not overlook the other effects, but must assign to each of them a
  • particular weight and authority, in proportion as we have found it to be
  • more or less frequent. It is more probable, in almost every country of
  • Europe, that there will be frost sometime in January, than that the
  • weather will continue open throughout that whole month; though this
  • probability varies according to the different climates, and approaches
  • to a certainty in the more northern kingdoms. Here then it seems
  • evident, that, when we transfer the past to the future, in order to
  • determine the effect, which will result from any cause, we transfer all
  • the different events, in the same proportion as they have appeared in
  • the past, and conceive one to have existed a hundred times, for
  • instance, another ten times, and another once. As a great number of
  • views do here concur in one event, they fortify and confirm it to the
  • imagination, beget that sentiment which we call _belief,_ and give its
  • object the preference above the contrary event, which is not supported
  • by an equal number of experiments, and recurs not so frequently to the
  • thought in transferring the past to the future. Let any one try to
  • account for this operation of the mind upon any of the received systems
  • of philosophy, and he will be sensible of the difficulty. For my part, I
  • shall think it sufficient, if the present hints excite the curiosity of
  • philosophers, and make them sensible how defective all common theories
  • are in treating of such curious and such sublime subjects.
  • SECTION VII.
  • OF THE IDEA OF NECESSARY CONNEXION.
  • PART I.
  • 48. The great advantage of the mathematical sciences above the moral
  • consists in this, that the ideas of the former, being sensible, are
  • always clear and determinate, the smallest distinction between them is
  • immediately perceptible, and the same terms are still expressive of the
  • same ideas, without ambiguity or variation. An oval is never mistaken
  • for a circle, nor an hyperbola for an ellipsis. The isosceles and
  • scalenum are distinguished by boundaries more exact than vice and
  • virtue, right and wrong. If any term be defined in geometry, the mind
  • readily, of itself, substitutes, on all occasions, the definition for
  • the term defined: Or even when no definition is employed, the object
  • itself may be presented to the senses, and by that means be steadily and
  • clearly apprehended. But the finer sentiments of the mind, the
  • operations of the understanding, the various agitations of the passions,
  • though really in themselves distinct, easily escape us, when surveyed by
  • reflection; nor is it in our power to recal the original object, as
  • often as we have occasion to contemplate it. Ambiguity, by this means,
  • is gradually introduced into our reasonings: Similar objects are readily
  • taken to be the same: And the conclusion becomes at last very wide of
  • the premises.
  • One may safely, however, affirm, that, if we consider these sciences in
  • a proper light, their advantages and disadvantages nearly compensate
  • each other, and reduce both of them to a state of equality. If the mind,
  • with greater facility, retains the ideas of geometry clear and
  • determinate, it must carry on a much longer and more intricate chain of
  • reasoning, and compare ideas much wider of each other, in order to reach
  • the abstruser truths of that science. And if moral ideas are apt,
  • without extreme care, to fall into obscurity and confusion, the
  • inferences are always much shorter in these disquisitions, and the
  • intermediate steps, which lead to the conclusion, much fewer than in the
  • sciences which treat of quantity and number. In reality, there is
  • scarcely a proposition in Euclid so simple, as not to consist of more
  • parts, than are to be found in any moral reasoning which runs not into
  • chimera and conceit. Where we trace the principles of the human mind
  • through a few steps, we may be very well satisfied with our progress;
  • considering how soon nature throws a bar to all our enquiries concerning
  • causes, and reduces us to an acknowledgment of our ignorance. The chief
  • obstacle, therefore, to our improvement in the moral or metaphysical
  • sciences is the obscurity of the ideas, and ambiguity of the terms. The
  • principal difficulty in the mathematics is the length of inferences and
  • compass of thought, requisite to the forming of any conclusion. And,
  • perhaps, our progress in natural philosophy is chiefly retarded by the
  • want of proper experiments and phaenomena, which are often discovered by
  • chance, and cannot always be found, when requisite, even by the most
  • diligent and prudent enquiry. As moral philosophy seems hitherto to have
  • received less improvement than either geometry or physics, we may
  • conclude, that, if there be any difference in this respect among these
  • sciences, the difficulties, which obstruct the progress of the former,
  • require superior care and capacity to be surmounted.
  • 49. There are no ideas, which occur in metaphysics, more obscure and
  • uncertain, than those of _power, force, energy_ or _necessary
  • connexion_, of which it is every moment necessary for us to treat in all
  • our disquisitions. We shall, therefore, endeavour, in this section, to
  • fix, if possible, the precise meaning of these terms, and thereby remove
  • some part of that obscurity, which is so much complained of in this
  • species of philosophy.
  • It seems a proposition, which will not admit of much dispute, that all
  • our ideas are nothing but copies of our impressions, or, in other words,
  • that it is impossible for us to _think_ of any thing, which we have not
  • antecedently _felt_, either by our external or internal senses. I have
  • endeavoured[10] to explain and prove this proposition, and have expressed
  • my hopes, that, by a proper application of it, men may reach a greater
  • clearness and precision in philosophical reasonings, than what they have
  • hitherto been able to attain. Complex ideas may, perhaps, be well known
  • by definition, which is nothing but an enumeration of those parts or
  • simple ideas, that compose them. But when we have pushed up definitions
  • to the most simple ideas, and find still some ambiguity and obscurity;
  • what resource are we then possessed of? By what invention can we throw
  • light upon these ideas, and render them altogether precise and
  • determinate to our intellectual view? Produce the impressions or
  • original sentiments, from which the ideas are copied. These impressions
  • are all strong and sensible. They admit not of ambiguity. They are not
  • only placed in a full light themselves, but may throw light on their
  • correspondent ideas, which lie in obscurity. And by this means, we may,
  • perhaps, attain a new microscope or species of optics, by which, in the
  • moral sciences, the most minute, and most simple ideas may be so
  • enlarged as to fall readily under our apprehension, and be equally known
  • with the grossest and most sensible ideas, that can be the object of
  • our enquiry.
  • [10] Section II.
  • 50. To be fully acquainted, therefore, with the idea of power or
  • necessary connexion, let us examine its impression; and in order to find
  • the impression with greater certainty, let us search for it in all the
  • sources, from which it may possibly be derived.
  • When we look about us towards external objects, and consider the
  • operation of causes, we are never able, in a single instance, to
  • discover any power or necessary connexion; any quality, which binds the
  • effect to the cause, and renders the one an infallible consequence of
  • the other. We only find, that the one does actually, in fact, follow the
  • other. The impulse of one billiard-ball is attended with motion in the
  • second. This is the whole that appears to the _outward_ senses. The mind
  • feels no sentiment or _inward_ impression from this succession of
  • objects: Consequently, there is not, in any single, particular instance
  • of cause and effect, any thing which can suggest the idea of power or
  • necessary connexion.
  • From the first appearance of an object, we never can conjecture what
  • effect will result from it. But were the power or energy of any cause
  • discoverable by the mind, we could foresee the effect, even without
  • experience; and might, at first, pronounce with certainty concerning it,
  • by mere dint of thought and reasoning.
  • In reality, there is no part of matter, that does ever, by its sensible
  • qualities, discover any power or energy, or give us ground to imagine,
  • that it could produce any thing, or be followed by any other object,
  • which we could denominate its effect. Solidity, extension, motion; these
  • qualities are all complete in themselves, and never point out any other
  • event which may result from them. The scenes of the universe are
  • continually shifting, and one object follows another in an uninterrupted
  • succession; but the power of force, which actuates the whole machine, is
  • entirely concealed from us, and never discovers itself in any of the
  • sensible qualities of body. We know, that, in fact, heat is a constant
  • attendant of flame; but what is the connexion between them, we have no
  • room so much as to conjecture or imagine. It is impossible, therefore,
  • that the idea of power can be derived from the contemplation of bodies,
  • in single instances of their operation; because no bodies ever discover
  • any power, which can be the original of this idea.[11]
  • [11] Mr. Locke, in his chapter of power, says that, finding
  • from experience, that there are several new productions in
  • nature, and concluding that there must somewhere be a power
  • capable of producing them, we arrive at last by this reasoning
  • at the idea of power. But no reasoning can ever give us a new,
  • original, simple idea; as this philosopher himself confesses.
  • This, therefore, can never be the origin of that idea.
  • 51. Since, therefore, external objects as they appear to the senses,
  • give us no idea of power or necessary connexion, by their operation in
  • particular instances, let us see, whether this idea be derived from
  • reflection on the operations of our own minds, and be copied from any
  • internal impression. It may be said, that we are every moment conscious
  • of internal power; while we feel, that, by the simple command of our
  • will, we can move the organs of our body, or direct the faculties of our
  • mind. An act of volition produces motion in our limbs, or raises a new
  • idea in our imagination. This influence of the will we know by
  • consciousness. Hence we acquire the idea of power or energy; and are
  • certain, that we ourselves and all other intelligent beings are
  • possessed of power. This idea, then, is an idea of reflection, since it
  • arises from reflecting on the operations of our own mind, and on the
  • command which is exercised by will, both over the organs of the body and
  • faculties of the soul.
  • 52. We shall proceed to examine this pretension; and first with regard
  • to the influence of volition over the organs of the body. This
  • influence, we may observe, is a fact, which, like all other natural
  • events, can be known only by experience, and can never be foreseen from
  • any apparent energy or power in the cause, which connects it with the
  • effect, and renders the one an infallible consequence of the other. The
  • motion of our body follows upon the command of our will. Of this we are
  • every moment conscious. But the means, by which this is effected; the
  • energy, by which the will performs so extraordinary an operation; of
  • this we are so far from being immediately conscious, that it must for
  • ever escape our most diligent enquiry.
  • For _first_; is there any principle in all nature more mysterious than
  • the union of soul with body; by which a supposed spiritual substance
  • acquires such an influence over a material one, that the most refined
  • thought is able to actuate the grossest matter? Were we empowered, by a
  • secret wish, to remove mountains, or control the planets in their orbit;
  • this extensive authority would not be more extraordinary, nor more
  • beyond our comprehension. But if by consciousness we perceived any power
  • or energy in the will, we must know this power; we must know its
  • connexion with the effect; we must know the secret union of soul and
  • body, and the nature of both these substances; by which the one is able
  • to operate, in so many instances, upon the other.
  • _Secondly_, We are not able to move all the organs of the body with a
  • like authority; though we cannot assign any reason besides experience,
  • for so remarkable a difference between one and the other. Why has the
  • will an influence over the tongue and fingers, not over the heart or
  • liver? This question would never embarrass us, were we conscious of a
  • power in the former case, not in the latter. We should then perceive,
  • independent of experience, why the authority of will over the organs of
  • the body is circumscribed within such particular limits. Being in that
  • case fully acquainted with the power or force, by which it operates, we
  • should also know, why its influence reaches precisely to such
  • boundaries, and no farther.
  • A man, suddenly struck with palsy in the leg or arm, or who had newly
  • lost those members, frequently endeavours, at first to move them, and
  • employ them in their usual offices. Here he is as much conscious of
  • power to command such limbs, as a man in perfect health is conscious of
  • power to actuate any member which remains in its natural state and
  • condition. But consciousness never deceives. Consequently, neither in
  • the one case nor in the other, are we ever conscious of any power. We
  • learn the influence of our will from experience alone. And experience
  • only teaches us, how one event constantly follows another; without
  • instructing us in the secret connexion, which binds them together, and
  • renders them inseparable.
  • _Thirdly,_ We learn from anatomy, that the immediate object of power in
  • voluntary motion, is not the member itself which is moved, but certain
  • muscles, and nerves, and animal spirits, and, perhaps, something still
  • more minute and more unknown, through which the motion is successively
  • propagated, ere it reach the member itself whose motion is the immediate
  • object of volition. Can there be a more certain proof, that the power,
  • by which this whole operation is performed, so far from being directly
  • and fully known by an inward sentiment or consciousness, is, to the last
  • degree mysterious and unintelligible? Here the mind wills a certain
  • event: Immediately another event, unknown to ourselves, and totally
  • different from the one intended, is produced: This event produces
  • another, equally unknown: Till at last, through a long succession, the
  • desired event is produced. But if the original power were felt, it must
  • be known: Were it known, its effect also must be known; since all power
  • is relative to its effect. And _vice versa,_ if the effect be not known,
  • the power cannot be known nor felt. How indeed can we be conscious of a
  • power to move our limbs, when we have no such power; but only that to
  • move certain animal spirits, which, though they produce at last the
  • motion of our limbs, yet operate in such a manner as is wholly beyond
  • our comprehension?
  • We may, therefore, conclude from the whole, I hope, without any
  • temerity, though with assurance; that our idea of power is not copied
  • from any sentiment or consciousness of power within ourselves, when we
  • give rise to animal motion, or apply our limbs to their proper use and
  • office. That their motion follows the command of the will is a matter of
  • common experience, like other natural events: But the power or energy by
  • which this is effected, like that in other natural events, is unknown
  • and inconceivable.[12]
  • [12] It may be pretended, that the resistance which we meet
  • with in bodies, obliging us frequently to exert our force, and
  • call up all our power, this gives us the idea of force and
  • power. It is this _nisus_, or strong endeavour, of which we are
  • conscious, that is the original impression from which this idea
  • is copied. But, first, we attribute power to a vast number of
  • objects, where we never can suppose this resistance or exertion
  • of force to take place; to the Supreme Being, who never meets
  • with any resistance; to the mind in its command over its ideas
  • and limbs, in common thinking and motion, where the effect
  • follows immediately upon the will, without any exertion or
  • summoning up of force; to inanimate matter, which is not
  • capable of this sentiment. _Secondly,_ This sentiment of an
  • endeavour to overcome resistance has no known connexion with
  • any event: What follows it, we know by experience; but could
  • not know it _à priori._ It must, however, be confessed, that
  • the animal _nisus,_ which we experience, though it can afford
  • no accurate precise idea of power, enters very much into that
  • vulgar, inaccurate idea, which is formed of it.
  • 53. Shall we then assert, that we are conscious of a power or energy in
  • our own minds, when, by an act or command of our will, we raise up a new
  • idea, fix the mind to the contemplation of it, turn it on all sides, and
  • at last dismiss it for some other idea, when we think that we have
  • surveyed it with sufficient accuracy? I believe the same arguments will
  • prove, that even this command of the will gives us no real idea of force
  • or energy.
  • _First,_ It must be allowed, that, when we know a power, we know that
  • very circumstance in the cause, by which it is enabled to produce the
  • effect: For these are supposed to be synonimous. We must, therefore,
  • know both the cause and effect, and the relation between them. But do we
  • pretend to be acquainted with the nature of the human soul and the
  • nature of an idea, or the aptitude of the one to produce the other? This
  • is a real creation; a production of something out of nothing: Which
  • implies a power so great, that it may seem, at first sight, beyond the
  • reach of any being, less than infinite. At least it must be owned, that
  • such a power is not felt, nor known, nor even conceivable by the mind.
  • We only feel the event, namely, the existence of an idea, consequent to
  • a command of the will: But the manner, in which this operation is
  • performed, the power by which it is produced, is entirely beyond our
  • comprehension.
  • _Secondly_, The command of the mind over itself is limited, as well as
  • its command over the body; and these limits are not known by reason, or
  • any acquaintance with the nature of cause and effect, but only by
  • experience and observation, as in all other natural events and in the
  • operation of external objects. Our authority over our sentiments and
  • passions is much weaker than that over our ideas; and even the latter
  • authority is circumscribed within very narrow boundaries. Will any one
  • pretend to assign the ultimate reason of these boundaries, or show why
  • the power is deficient in one case, not in another.
  • _Thirdly_, This self-command is very different at different times. A man
  • in health possesses more of it than one languishing with sickness. We
  • are more master of our thoughts in the morning than in the evening:
  • Fasting, than after a full meal. Can we give any reason for these
  • variations, except experience? Where then is the power, of which we
  • pretend to be conscious? Is there not here, either in a spiritual or
  • material substance, or both, some secret mechanism or structure of
  • parts, upon which the effect depends, and which, being entirely unknown
  • to us, renders the power or energy of the will equally unknown and
  • incomprehensible?
  • Volition is surely an act of the mind, with which we are sufficiently
  • acquainted. Reflect upon it. Consider it on all sides. Do you find
  • anything in it like this creative power, by which it raises from nothing
  • a new idea, and with a kind of _Fiat_, imitates the omnipotence of its
  • Maker, if I may be allowed so to speak, who called forth into existence
  • all the various scenes of nature? So far from being conscious of this
  • energy in the will, it requires as certain experience as that of which
  • we are possessed, to convince us that such extraordinary effects do ever
  • result from a simple act of volition.
  • 54. The generality of mankind never find any difficulty in accounting
  • for the more common and familiar operations of nature--such as the
  • descent of heavy bodies, the growth of plants, the generation of
  • animals, or the nourishment of bodies by food: But suppose that, in all
  • these cases, they perceive the very force or energy of the cause, by
  • which it is connected with its effect, and is for ever infallible in its
  • operation. They acquire, by long habit, such a turn of mind, that, upon
  • the appearance of the cause, they immediately expect with assurance its
  • usual attendant, and hardly conceive it possible that any other event
  • could result from it. It is only on the discovery of extraordinary
  • phaenomena, such as earthquakes, pestilence, and prodigies of any kind,
  • that they find themselves at a loss to assign a proper cause, and to
  • explain the manner in which the effect is produced by it. It is usual
  • for men, in such difficulties, to have recourse to some invisible
  • intelligent principle[13] as the immediate cause of that event which
  • surprises them, and which, they think, cannot be accounted for from the
  • common powers of nature. But philosophers, who carry their scrutiny a
  • little farther, immediately perceive that, even in the most familiar
  • events, the energy of the cause is as unintelligible as in the most
  • unusual, and that we only learn by experience the frequent _Conjunction_
  • of objects, without being ever able to comprehend anything like
  • _Connexion_ between them.
  • [13] [Greek: theos apo maechanaes.]
  • 55. Here, then, many philosophers think themselves obliged by reason to
  • have recourse, on all occasions, to the same principle, which the vulgar
  • never appeal to but in cases that appear miraculous and supernatural.
  • They acknowledge mind and intelligence to be, not only the ultimate and
  • original cause of all things, but the immediate and sole cause of every
  • event which appears in nature. They pretend that those objects which are
  • commonly denominated _causes,_ are in reality nothing but _occasions;_
  • and that the true and direct principle of every effect is not any power
  • or force in nature, but a volition of the Supreme Being, who wills that
  • such particular objects should for ever be conjoined with each other.
  • Instead of saying that one billiard-ball moves another by a force which
  • it has derived from the author of nature, it is the Deity himself, they
  • say, who, by a particular volition, moves the second ball, being
  • determined to this operation by the impulse of the first ball, in
  • consequence of those general laws which he has laid down to himself in
  • the government of the universe. But philosophers advancing still in
  • their inquiries, discover that, as we are totally ignorant of the power
  • on which depends the mutual operation of bodies, we are no less ignorant
  • of that power on which depends the operation of mind on body, or of body
  • on mind; nor are we able, either from our senses or consciousness, to
  • assign the ultimate principle in one case more than in the other. The
  • same ignorance, therefore, reduces them to the same conclusion. They
  • assert that the Deity is the immediate cause of the union between soul
  • and body; and that they are not the organs of sense, which, being
  • agitated by external objects, produce sensations in the mind; but that
  • it is a particular volition of our omnipotent Maker, which excites such
  • a sensation, in consequence of such a motion in the organ. In like
  • manner, it is not any energy in the will that produces local motion in
  • our members: It is God himself, who is pleased to second our will, in
  • itself impotent, and to command that motion which we erroneously
  • attribute to our own power and efficacy. Nor do philosophers stop at
  • this conclusion. They sometimes extend the same inference to the mind
  • itself, in its internal operations. Our mental vision or conception of
  • ideas is nothing but a revelation made to us by our Maker. When we
  • voluntarily turn our thoughts to any object, and raise up its image in
  • the fancy, it is not the will which creates that idea: It is the
  • universal Creator, who discovers it to the mind, and renders it
  • present to us.
  • 56. Thus, according to these philosophers, every thing is full of God.
  • Not content with the principle, that nothing exists but by his will,
  • that nothing possesses any power but by his concession: They rob nature,
  • and all created beings, of every power, in order to render their
  • dependence on the Deity still more sensible and immediate. They consider
  • not that, by this theory, they diminish, instead of magnifying, the
  • grandeur of those attributes, which they affect so much to celebrate. It
  • argues surely more power in the Deity to delegate a certain degree of
  • power to inferior creatures than to produce every thing by his own
  • immediate volition. It argues more wisdom to contrive at first the
  • fabric of the world with such perfect foresight that, of itself, and by
  • its proper operation, it may serve all the purposes of providence, than
  • if the great Creator were obliged every moment to adjust its parts, and
  • animate by his breath all the wheels of that stupendous machine.
  • But if we would have a more philosophical confutation of this theory,
  • perhaps the two following reflections may suffice.
  • 57. _First_, it seems to me that this theory of the universal energy and
  • operation of the Supreme Being is too bold ever to carry conviction with
  • it to a man, sufficiently apprized of the weakness of human reason, and
  • the narrow limits to which it is confined in all its operations. Though
  • the chain of arguments which conduct to it were ever so logical, there
  • must arise a strong suspicion, if not an absolute assurance, that it has
  • carried us quite beyond the reach of our faculties, when it leads to
  • conclusions so extraordinary, and so remote from common life and
  • experience. We are got into fairy land, long ere we have reached the
  • last steps of our theory; and _there_ we have no reason to trust our
  • common methods of argument, or to think that our usual analogies and
  • probabilities have any authority. Our line is too short to fathom such
  • immense abysses. And however we may flatter ourselves that we are
  • guided, in every step which we take, by a kind of verisimilitude and
  • experience, we may be assured that this fancied experience has no
  • authority when we thus apply it to subjects that lie entirely out of the
  • sphere of experience. But on this we shall have occasion to touch
  • afterwards.[14]
  • [14] Section XII.
  • _Secondly,_ I cannot perceive any force in the arguments on which this
  • theory is founded. We are ignorant, it is true, of the manner in which
  • bodies operate on each other: Their force or energy is entirely
  • incomprehensible: But are we not equally ignorant of the manner or force
  • by which a mind, even the supreme mind, operates either on itself or on
  • body? Whence, I beseech you, do we acquire any idea of it? We have no
  • sentiment or consciousness of this power in ourselves. We have no idea
  • of the Supreme Being but what we learn from reflection on our own
  • faculties. Were our ignorance, therefore, a good reason for rejecting
  • any thing, we should be led into that principle of denying all energy in
  • the Supreme Being as much as in the grossest matter. We surely
  • comprehend as little the operations of one as of the other. Is it more
  • difficult to conceive that motion may arise from impulse than that it
  • may arise from volition? All we know is our profound ignorance in
  • both cases[15].
  • [15] I need not examine at length the _vis inertiae_ which is
  • so much talked of in the new philosophy, and which is ascribed
  • to matter. We find by experience, that a body at rest or in
  • motion continues for ever in its present state, till put from
  • it by some new cause; and that a body impelled takes as much
  • motion from the impelling body as it acquires itself. These are
  • facts. When we call this a _vis inertiae_, we only mark these
  • facts, without pretending to have any idea of the inert power;
  • in the same manner as, when we talk of gravity, we mean certain
  • effects, without comprehending that active power. It was never
  • the meaning of Sir ISAAC NEWTON to rob second causes of all
  • force or energy; though some of his followers have endeavoured
  • to establish that theory upon his authority. On the contrary,
  • that great philosopher had recourse to an etherial active fluid
  • to explain his universal attraction; though he was so cautious
  • and modest as to allow, that it was a mere hypothesis, not to
  • be insisted on, without more experiments. I must confess, that
  • there is something in the fate of opinions a little
  • extraordinary. DES CARTES insinuated that doctrine of the
  • universal and sole efficacy of the Deity, without insisting on
  • it. MALEBRANCHE and other CARTESIANS made it the foundation of
  • all their philosophy. It had, however, no authority in England.
  • LOCKE, CLARKE, and CUDWORTH, never so much as take notice of
  • it, but suppose all along, that matter has a real, though
  • subordinate and derived power. By what means has it become so
  • prevalent among our modern metaphysicians?
  • PART II.
  • 58. But to hasten to a conclusion of this argument, which is already
  • drawn out to too great a length: We have sought in vain for an idea of
  • power or necessary connexion in all the sources from which we could
  • suppose it to be derived. It appears that, in single instances of the
  • operation of bodies, we never can, by our utmost scrutiny, discover any
  • thing but one event following another, without being able to comprehend
  • any force or power by which the cause operates, or any connexion between
  • it and its supposed effect. The same difficulty occurs in contemplating
  • the operations of mind on body--where we observe the motion of the
  • latter to follow upon the volition of the former, but are not able to
  • observe or conceive the tie which binds together the motion and
  • volition, or the energy by which the mind produces this effect. The
  • authority of the will over its own faculties and ideas is not a whit
  • more comprehensible: So that, upon the whole, there appears not,
  • throughout all nature, any one instance of connexion which is
  • conceivable by us. All events seem entirely loose and separate. One
  • event follows another; but we never can observe any tie between them.
  • They seem _conjoined_, but never _connected_. And as we can have no idea
  • of any thing which never appeared to our outward sense or inward
  • sentiment, the necessary conclusion _seems_ to be that we have no idea
  • of connexion or power at all, and that these words are absolutely
  • without any meaning, when employed either in philosophical reasonings or
  • common life.
  • 59. But there still remains one method of avoiding this conclusion, and
  • one source which we have not yet examined. When any natural object or
  • event is presented, it is impossible for us, by any sagacity or
  • penetration, to discover, or even conjecture, without experience, what
  • event will result from it, or to carry our foresight beyond that object
  • which is immediately present to the memory and senses. Even after one
  • instance or experiment where we have observed a particular event to
  • follow upon another, we are not entitled to form a general rule, or
  • foretell what will happen in like cases; it being justly esteemed an
  • unpardonable temerity to judge of the whole course of nature from one
  • single experiment, however accurate or certain. But when one particular
  • species of event has always, in all instances, been conjoined with
  • another, we make no longer any scruple of foretelling one upon the
  • appearance of the other, and of employing that reasoning, which can
  • alone assure us of any matter of fact or existence. We then call the one
  • object, _Cause;_ the other, _Effect._ We suppose that there is some
  • connexion between them; some power in the one, by which it infallibly
  • produces the other, and operates with the greatest certainty and
  • strongest necessity.
  • It appears, then, that this idea of a necessary connexion among events
  • arises from a number of similar instances which occur of the constant
  • conjunction of these events; nor can that idea ever be suggested by any
  • one of these instances, surveyed in all possible lights and positions.
  • But there is nothing in a number of instances, different from every
  • single instance, which is supposed to be exactly similar; except only,
  • that after a repetition of similar instances, the mind is carried by
  • habit, upon the appearance of one event, to expect its usual attendant,
  • and to believe that it will exist. This connexion, therefore, which we
  • _feel_ in the mind, this customary transition of the imagination from
  • one object to its usual attendant, is the sentiment or impression from
  • which we form the idea of power or necessary connexion. Nothing farther
  • is in the case. Contemplate the subject on all sides; you will never
  • find any other origin of that idea. This is the sole difference between
  • one instance, from which we can never receive the idea of connexion, and
  • a number of similar instances, by which it is suggested. The first time
  • a man saw the communication of motion by impulse, as by the shock of two
  • billiard balls, he could not pronounce that the one event was
  • _connected:_ but only that it was _conjoined_ with the other. After he
  • has observed several instances of this nature, he then pronounces them
  • to be _connected._ What alteration has happened to give rise to this new
  • idea of _connexion?_ Nothing but that he now _feels_ these events to be
  • connected in his imagination, and can readily foretell the existence of
  • one from the appearance of the other. When we say, therefore, that one
  • object is connected with another, we mean only that they have acquired a
  • connexion in our thought, and give rise to this inference, by which they
  • become proofs of each other's existence: A conclusion which is somewhat
  • extraordinary, but which seems founded on sufficient evidence. Nor will
  • its evidence be weakened by any general diffidence of the understanding,
  • or sceptical suspicion concerning every conclusion which is new and
  • extraordinary. No conclusions can be more agreeable to scepticism than
  • such as make discoveries concerning the weakness and narrow limits of
  • human reason and capacity.
  • 60. And what stronger instance can be produced of the surprising
  • ignorance and weakness of the understanding than the present? For
  • surely, if there be any relation among objects which it imports to us to
  • know perfectly, it is that of cause and effect. On this are founded all
  • our reasonings concerning matter of fact or existence. By means of it
  • alone we attain any assurance concerning objects which are removed from
  • the present testimony of our memory and senses. The only immediate
  • utility of all sciences, is to teach us, how to control and regulate
  • future events by their causes. Our thoughts and enquiries are,
  • therefore, every moment, employed about this relation: Yet so imperfect
  • are the ideas which we form concerning it, that it is impossible to give
  • any just definition of cause, except what is drawn from something
  • extraneous and foreign to it. Similar objects are always conjoined with
  • similar. Of this we have experience. Suitably to this experience,
  • therefore, we may define a cause to be _an object, followed by another,
  • and where all the objects similar to the first are followed by objects
  • similar to the second_. Or in other words _where, if the first object
  • had not been, the second never had existed_. The appearance of a cause
  • always conveys the mind, by a customary transition, to the idea of the
  • effect. Of this also we have experience. We may, therefore, suitably to
  • this experience, form another definition of cause, and call it, _an
  • object followed by another, and whose appearance always conveys the
  • thought to that other._ But though both these definitions be drawn from
  • circumstances foreign to the cause, we cannot remedy this inconvenience,
  • or attain any more perfect definition, which may point out that
  • circumstance in the cause, which gives it a connexion with its effect.
  • We have no idea of this connexion, nor even any distinct notion what it
  • is we desire to know, when we endeavour at a conception of it. We say,
  • for instance, that the vibration of this string is the cause of this
  • particular sound. But what do we mean by that affirmation? We either
  • mean _that this vibration is followed by this sound, and that all
  • similar vibrations have been followed by similar sounds:_ Or, _that this
  • vibration is followed by this sound, and that upon the appearance of one
  • the mind anticipates the senses, and forms immediately an idea of the
  • other._ We may consider the relation of cause and effect in either of
  • these two lights; but beyond these, we have no idea of it.[16]
  • [16] According to these explications and definitions, the idea
  • of _power_ is relative as much as that of _cause;_ and both
  • have a reference to an effect, or some other event constantly
  • conjoined with the former. When we consider the _unknown_
  • circumstance of an object, by which the degree or quantity of
  • its effect is fixed and determined, we call that its power: And
  • accordingly, it is allowed by all philosophers, that the effect
  • is the measure of the power. But if they had any idea of power,
  • as it is in itself, why could not they Measure it in itself?
  • The dispute whether the force of a body in motion be as its
  • velocity, or the square of its velocity; this dispute, I say,
  • need not be decided by comparing its effects in equal or
  • unequal times; but by a direct mensuration and comparison.
  • As to the frequent use of the words, Force, Power, Energy, &c.,
  • which every where occur in common conversation, as well as in
  • philosophy; that is no proof, that we are acquainted, in any
  • instance, with the connecting principle between cause and
  • effect, or can account ultimately for the production of one
  • thing to another. These words, as commonly used, have very
  • loose meanings annexed to them; and their ideas are very
  • uncertain and confused. No animal can put external bodies in
  • motion without the sentiment of a _nisus_ or endeavour; and
  • every animal has a sentiment or feeling from the stroke or blow
  • of an external object, that is in motion. These sensations,
  • which are merely animal, and from which we can _à priori_ draw
  • no inference, we are apt to transfer to inanimate objects, and
  • to suppose, that they have some such feelings, whenever they
  • transfer or receive motion. With regard to energies, which are
  • exerted, without our annexing to them any idea of communicated
  • motion, we consider only the constant experienced conjunction
  • of the events; and as we _feel_ a customary connexion between
  • the ideas, we transfer that feeling to the objects; as nothing
  • is more usual than to apply to external bodies every internal
  • sensation, which they occasion.
  • 61. To recapitulate, therefore, the reasonings of this section: Every
  • idea is copied from some preceding impression or sentiment; and where we
  • cannot find any impression, we may be certain that there is no idea. In
  • all single instances of the operation of bodies or minds, there is
  • nothing that produces any impression, nor consequently can suggest any
  • idea of power or necessary connexion. But when many uniform instances
  • appear, and the same object is always followed by the same event; we
  • then begin to entertain the notion of cause and connexion. We then
  • _feel_ a new sentiment or impression, to wit, a customary connexion in
  • the thought or imagination between one object and its usual attendant;
  • and this sentiment is the original of that idea which we seek for. For
  • as this idea arises from a number of similar instances, and not from any
  • single instance, it must arise from that circumstance, in which the
  • number of instances differ from every individual instance. But this
  • customary connexion or transition of the imagination is the only
  • circumstance in which they differ. In every other particular they are
  • alike. The first instance which we saw of motion communicated by the
  • shock of two billiard balls (to return to this obvious illustration) is
  • exactly similar to any instance that may, at present, occur to us;
  • except only, that we could not, at first, _infer_ one event from the
  • other; which we are enabled to do at present, after so long a course of
  • uniform experience. I know not whether the reader will readily apprehend
  • this reasoning. I am afraid that, should I multiply words about it, or
  • throw it into a greater variety of lights, it would only become more
  • obscure and intricate. In all abstract reasonings there is one point of
  • view which, if we can happily hit, we shall go farther towards
  • illustrating the subject than by all the eloquence and copious
  • expression in the world. This point of view we should endeavour to
  • reach, and reserve the flowers of rhetoric for subjects which are more
  • adapted to them.
  • SECTION VIII.
  • OF LIBERTY AND NECESSITY.
  • PART I.
  • 62. It might reasonably be expected in questions which have been
  • canvassed and disputed with great eagerness, since the first origin of
  • science and philosophy, that the meaning of all the terms, at least,
  • should have been agreed upon among the disputants; and our enquiries, in
  • the course of two thousand years, been able to pass from words to the
  • true and real subject of the controversy. For how easy may it seem to
  • give exact definitions of the terms employed in reasoning, and make
  • these definitions, not the mere sound of words, the object of future
  • scrutiny and examination? But if we consider the matter more narrowly,
  • we shall be apt to draw a quite opposite conclusion. From this
  • circumstance alone, that a controversy has been long kept on foot, and
  • remains still undecided, we may presume that there is some ambiguity in
  • the expression, and that the disputants affix different ideas to the
  • terms employed in the controversy. For as the faculties of the mind are
  • supposed to be naturally alike in every individual; otherwise nothing
  • could be more fruitless than to reason or dispute together; it were
  • impossible, if men affix the same ideas to their terms, that they could
  • so long form different opinions of the same subject; especially when
  • they communicate their views, and each party turn themselves on all
  • sides, in search of arguments which may give them the victory over their
  • antagonists. It is true, if men attempt the discussion of questions
  • which lie entirely beyond the reach of human capacity, such as those
  • concerning the origin of worlds, or the economy of the intellectual
  • system or region of spirits, they may long beat the air in their
  • fruitless contests, and never arrive at any determinate conclusion. But
  • if the question regard any subject of common life and experience,
  • nothing, one would think, could preserve the dispute so long undecided
  • but some ambiguous expressions, which keep the antagonists still at a
  • distance, and hinder them from grappling with each other.
  • 63. This has been the case in the long disputed question concerning
  • liberty and necessity; and to so remarkable a degree that, if I be not
  • much mistaken, we shall find, that all mankind, both learned and
  • ignorant, have always been of the same opinion with regard to this
  • subject, and that a few intelligible definitions would immediately have
  • put an end to the whole controversy. I own that this dispute has been so
  • much canvassed on all hands, and has led philosophers into such a
  • labyrinth of obscure sophistry, that it is no wonder, if a sensible
  • reader indulge his ease so far as to turn a deaf ear to the proposal of
  • such a question, from which he can expect neither instruction or
  • entertainment. But the state of the argument here proposed may, perhaps,
  • serve to renew his attention; as it has more novelty, promises at least
  • some decision of the controversy, and will not much disturb his ease by
  • any intricate or obscure reasoning.
  • I hope, therefore, to make it appear that all men have ever agreed in
  • the doctrine both of necessity and of liberty, according to any
  • reasonable sense, which can be put on these terms; and that the whole
  • controversy has hitherto turned merely upon words. We shall begin with
  • examining the doctrine of necessity.
  • 64. It is universally allowed that matter, in all its operations, is
  • actuated by a necessary force, and that every natural effect is so
  • precisely determined by the energy of its cause that no other effect, in
  • such particular circumstances, could possibly have resulted from it. The
  • degree and direction of every motion is, by the laws of nature,
  • prescribed with such exactness that a living creature may as soon arise
  • from the shock of two bodies as motion in any other degree or direction
  • than what is actually produced by it. Would we, therefore, form a just
  • and precise idea of _necessity_, we must consider whence that idea
  • arises when we apply it to the operation of bodies.
  • It seems evident that, if all the scenes of nature were continually
  • shifted in such a manner that no two events bore any resemblance to each
  • other, but every object was entirely new, without any similitude to
  • whatever had been seen before, we should never, in that case, have
  • attained the least idea of necessity, or of a connexion among these
  • objects. We might say, upon such a supposition, that one object or event
  • has followed another; not that one was produced by the other. The
  • relation of cause and effect must be utterly unknown to mankind.
  • Inference and reasoning concerning the operations of nature would, from
  • that moment, be at an end; and the memory and senses remain the only
  • canals, by which the knowledge of any real existence could possibly have
  • access to the mind. Our idea, therefore, of necessity and causation
  • arises entirely from the uniformity observable in the operations of
  • nature, where similar objects are constantly conjoined together, and the
  • mind is determined by custom to infer the one from the appearance of the
  • other. These two circumstances form the whole of that necessity, which
  • we ascribe to matter. Beyond the constant _conjunction_ of similar
  • objects, and the consequent _inference_ from one to the other, we have
  • no notion of any necessity or connexion.
  • If it appear, therefore, that all mankind have ever allowed, without any
  • doubt or hesitation, that these two circumstances take place in the
  • voluntary actions of men, and in the operations of mind; it must follow,
  • that all mankind have ever agreed in the doctrine of necessity, and that
  • they have hitherto disputed, merely for not understanding each other.
  • 65. As to the first circumstance, the constant and regular conjunction
  • of similar events, we may possibly satisfy ourselves by the following
  • considerations. It is universally acknowledged that there is a great
  • uniformity among the actions of men, in all nations and ages, and that
  • human nature remains still the same, in its principles and operations.
  • The same motives always produce the same actions. The same events follow
  • from the same causes. Ambition, avarice, self-love, vanity, friendship,
  • generosity, public spirit: these passions, mixed in various degrees, and
  • distributed through society, have been, from the beginning of the world,
  • and still are, the source of all the actions and enterprises, which have
  • ever been observed among mankind. Would you know the sentiments,
  • inclinations, and course of life of the Greeks and Romans? Study well
  • the temper and actions of the French and English: You cannot be much
  • mistaken in transferring to the former _most_ of the observations which
  • you have made with regard to the latter. Mankind are so much the same,
  • in all times and places, that history informs us of nothing new or
  • strange in this particular. Its chief use is only to discover the
  • constant and universal principles of human nature, by showing men in all
  • varieties of circumstances and situations, and furnishing us with
  • materials from which we may form our observations and become acquainted
  • with the regular springs of human action and behaviour. These records of
  • wars, intrigues, factions, and revolutions, are so many collections of
  • experiments, by which the politician or moral philosopher fixes the
  • principles of his science, in the same manner as the physician or
  • natural philosopher becomes acquainted with the nature of plants,
  • minerals, and other external objects, by the experiments which he forms
  • concerning them. Nor are the earth, water, and other elements, examined
  • by Aristotle, and Hippocrates, more like to those which at present lie
  • under our observation than the men described by Polybius and Tacitus are
  • to those who now govern the world.
  • Should a traveller, returning from a far country, bring us an account of
  • men, wholly different from any with whom we were ever acquainted; men,
  • who were entirely divested of avarice, ambition, or revenge; who knew no
  • pleasure but friendship, generosity, and public spirit; we should
  • immediately, from these circumstances, detect the falsehood, and prove
  • him a liar, with the same certainty as if he had stuffed his narration
  • with stories of centaurs and dragons, miracles and prodigies. And if we
  • would explode any forgery in history, we cannot make use of a more
  • convincing argument, than to prove, that the actions ascribed to any
  • person are directly contrary to the course of nature, and that no human
  • motives, in such circumstances, could ever induce him to such a conduct.
  • The veracity of Quintus Curtius is as much to be suspected, when he
  • describes the supernatural courage of Alexander, by which he was hurried
  • on singly to attack multitudes, as when he describes his supernatural
  • force and activity, by which he was able to resist them. So readily and
  • universally do we acknowledge a uniformity in human motives and actions
  • as well as in the operations of body.
  • Hence likewise the benefit of that experience, acquired by long life and
  • a variety of business and company, in order to instruct us in the
  • principles of human nature, and regulate our future conduct, as well as
  • speculation. By means of this guide, we mount up to the knowledge of
  • men's inclinations and motives, from their actions, expressions, and
  • even gestures; and again descend to the interpretation of their actions
  • from our knowledge of their motives and inclinations. The general
  • observations treasured up by a course of experience, give us the clue of
  • human nature, and teach us to unravel all its intricacies. Pretexts and
  • appearances no longer deceive us. Public declarations pass for the
  • specious colouring of a cause. And though virtue and honour be allowed
  • their proper weight and authority, that perfect disinterestedness, so
  • often pretended to, is never expected in multitudes and parties; seldom
  • in their leaders; and scarcely even in individuals of any rank or
  • station. But were there no uniformity in human actions, and were every
  • experiment which we could form of this kind irregular and anomalous, it
  • were impossible to collect any general observations concerning mankind;
  • and no experience, however accurately digested by reflection, would ever
  • serve to any purpose. Why is the aged husbandman more skilful in his
  • calling than the young beginner but because there is a certain
  • uniformity in the operation of the sun, rain, and earth towards the
  • production of vegetables; and experience teaches the old practitioner
  • the rules by which this operation is governed and directed.
  • 66. We must not, however, expect that this uniformity of human actions
  • should be carried to such a length as that all men, in the same
  • circumstances, will always act precisely in the same manner, without
  • making any allowance for the diversity of characters, prejudices, and
  • opinions. Such a uniformity in every particular, is found in no part of
  • nature. On the contrary, from observing the variety of conduct in
  • different men, we are enabled to form a greater variety of maxims, which
  • still suppose a degree of uniformity and regularity.
  • Are the manners of men different in different ages and countries? We
  • learn thence the great force of custom and education, which mould the
  • human mind from its infancy and form it into a fixed and established
  • character. Is the behaviour and conduct of the one sex very unlike that
  • of the other? Is it thence we become acquainted with the different
  • characters which nature has impressed upon the sexes, and which she
  • preserves with constancy and regularity? Are the actions of the same
  • person much diversified in the different periods of his life, from
  • infancy to old age? This affords room for many general observations
  • concerning the gradual change of our sentiments and inclinations, and
  • the different maxims which prevail in the different ages of human
  • creatures. Even the characters, which are peculiar to each individual,
  • have a uniformity in their influence; otherwise our acquaintance with
  • the persons and our observation of their conduct could never teach us
  • their dispositions, or serve to direct our behaviour with regard
  • to them.
  • 67. I grant it possible to find some actions, which seem to have no
  • regular connexion with any known motives, and are exceptions to all the
  • measures of conduct which have ever been established for the government
  • of men. But if we would willingly know what judgement should be formed
  • of such irregular and extraordinary actions, we may consider the
  • sentiments commonly entertained with regard to those irregular events
  • which appear in the course of nature, and the operations of external
  • objects. All causes are not conjoined to their usual effects with like
  • uniformity. An artificer, who handles only dead matter, may be
  • disappointed of his aim, as well as the politician, who directs the
  • conduct of sensible and intelligent agents.
  • The vulgar, who take things according to their first appearance,
  • attribute the uncertainty of events to such an uncertainty in the causes
  • as makes the latter often fail of their usual influence; though they
  • meet with no impediment in their operation. But philosophers, observing
  • that, almost in every part of nature, there is contained a vast variety
  • of springs and principles, which are hid, by reason of their minuteness
  • or remoteness, find, that it is at least possible the contrariety of
  • events may not proceed from any contingency in the cause, but from the
  • secret operation of contrary causes. This possibility is converted into
  • certainty by farther observation, when they remark that, upon an exact
  • scrutiny, a contrariety of effects always betrays a contrariety of
  • causes, and proceeds from their mutual opposition. A peasant can give no
  • better reason for the stopping of any clock or watch than to say that it
  • does not commonly go right: But an artist easily perceives that the same
  • force in the spring or pendulum has always the same influence on the
  • wheels; but fails of its usual effect, perhaps by reason of a grain of
  • dust, which puts a stop to the whole movement. From the observation of
  • several parallel instances, philosophers form a maxim that the connexion
  • between all causes and effects is equally necessary, and that its
  • seeming uncertainty in some instances proceeds from the secret
  • opposition of contrary causes.
  • Thus, for instance, in the human body, when the usual symptoms of health
  • or sickness disappoint our expectation; when medicines operate not with
  • their wonted powers; when irregular events follow from any particular
  • cause; the philosopher and physician are not surprised at the matter,
  • nor are ever tempted to deny, in general, the necessity and uniformity
  • of those principles by which the animal economy is conducted. They know
  • that a human body is a mighty complicated machine: That many secret
  • powers lurk in it, which are altogether beyond our comprehension: That
  • to us it must often appear very uncertain in its operations: And that
  • therefore the irregular events, which outwardly discover themselves, can
  • be no proof that the laws of nature are not observed with the greatest
  • regularity in its internal operations and government.
  • 68. The philosopher, if he be consistent, must apply the same reasoning
  • to the actions and volitions of intelligent agents. The most irregular
  • and unexpected resolutions of men may frequently be accounted for by
  • those who know every particular circumstance of their character and
  • situation. A person of an obliging disposition gives a peevish answer:
  • But he has the toothache, or has not dined. A stupid fellow discovers an
  • uncommon alacrity in his carriage: But he has met with a sudden piece of
  • good fortune. Or even when an action, as sometimes happens, cannot be
  • particularly accounted for, either by the person himself or by others;
  • we know, in general, that the characters of men are, to a certain
  • degree, inconstant and irregular. This is, in a manner, the constant
  • character of human nature; though it be applicable, in a more particular
  • manner, to some persons who have no fixed rule for their conduct, but
  • proceed in a continued course of caprice and inconstancy. The internal
  • principles and motives may operate in a uniform manner, notwithstanding
  • these seeming irregularities; in the same manner as the winds, rain,
  • clouds, and other variations of the weather are supposed to be governed
  • by steady principles; though not easily discoverable by human sagacity
  • and enquiry.
  • 69. Thus it appears, not only that the conjunction between motives and
  • voluntary actions is as regular and uniform as that between the cause
  • and effect in any part of nature; but also that this regular conjunction
  • has been universally acknowledged among mankind, and has never been the
  • subject of dispute, either in philosophy or common life. Now, as it is
  • from past experience that we draw all inferences concerning the future,
  • and as we conclude that objects will always be conjoined together which
  • we find to have always been conjoined; it may seem superfluous to prove
  • that this experienced uniformity in human actions is a source whence we
  • draw _inferences_ concerning them. But in order to throw the argument
  • into a greater variety of lights we shall also insist, though briefly,
  • on this latter topic.
  • The mutual dependence of men is so great in all societies that scarce
  • any human action is entirely complete in itself, or is performed without
  • some reference to the actions of others, which are requisite to make it
  • answer fully the intention of the agent. The poorest artificer, who
  • labours alone, expects at least the protection of the magistrate, to
  • ensure him the enjoyment of the fruits of his labour. He also expects
  • that, when he carries his goods to market, and offers them at a
  • reasonable price, he shall find purchasers, and shall be able, by the
  • money he acquires, to engage others to supply him with those commodities
  • which are requisite for his subsistence. In proportion as men extend
  • their dealings, and render their intercourse with others more
  • complicated, they always comprehend, in their schemes of life, a greater
  • variety of voluntary actions, which they expect, from the proper
  • motives, to co-operate with their own. In all these conclusions they
  • take their measures from past experience, in the same manner as in their
  • reasonings concerning external objects; and firmly believe that men, as
  • well as all the elements, are to continue, in their operations, the same
  • that they have ever found them. A manufacturer reckons upon the labour
  • of his servants for the execution of any work as much as upon the tools
  • which he employs, and would be equally surprised were his expectations
  • disappointed. In short, this experimental inference and reasoning
  • concerning the actions of others enters so much into human life that no
  • man, while awake, is ever a moment without employing it. Have we not
  • reason, therefore, to affirm that all mankind have always agreed in the
  • doctrine of necessity according to the foregoing definition and
  • explication of it?
  • 70. Nor have philosophers ever entertained a different opinion from the
  • people in this particular. For, not to mention that almost every action
  • of their life supposes that opinion, there are even few of the
  • speculative parts of learning to which it is not essential. What would
  • become of _history,_ had we not a dependence on the veracity of the
  • historian according to the experience which we have had of mankind? How
  • could _politics_ be a science, if laws and forms of goverment had not a
  • uniform influence upon society? Where would be the foundation of
  • _morals,_ if particular characters had no certain or determinate power
  • to produce particular sentiments, and if these sentiments had no
  • constant operation on actions? And with what pretence could we employ
  • our _criticism_ upon any poet or polite author, if we could not
  • pronounce the conduct and sentiments of his actors either natural or
  • unnatural to such characters, and in such circumstances? It seems almost
  • impossible, therefore, to engage either in science or action of any kind
  • without acknowledging the doctrine of necessity, and this _inference_
  • from motive to voluntary actions, from characters to conduct.
  • And indeed, when we consider how aptly _natural_ and _moral_ evidence
  • link together, and form only one chain of argument, we shall make no
  • scruple to allow that they are of the same nature, and derived from the
  • same principles. A prisoner who has neither money nor interest,
  • discovers the impossibility of his escape, as well when he considers the
  • obstinacy of the gaoler, as the walls and bars with which he is
  • surrounded; and, in all attempts for his freedom, chooses rather to work
  • upon the stone and iron of the one, than upon the inflexible nature of
  • the other. The same prisoner, when conducted to the scaffold, foresees
  • his death as certainly from the constancy and fidelity of his guards, as
  • from the operation of the axe or wheel. His mind runs along a certain
  • train of ideas: The refusal of the soldiers to consent to his escape;
  • the action of the executioner; the separation of the head and body;
  • bleeding, convulsive motions, and death. Here is a connected chain of
  • natural causes and voluntary actions; but the mind feels no difference
  • between them in passing from one link to another: Nor is less certain of
  • the future event than if it were connected with the objects present to
  • the memory or senses, by a train of causes, cemented together by what we
  • are pleased to call a _physical_ necessity. The same experienced union
  • has the same effect on the mind, whether the united objects be motives,
  • volition, and actions; or figure and motion. We may change the name of
  • things; but their nature and their operation on the understanding
  • never change.
  • Were a man, whom I know to be honest and opulent, and with whom I live
  • in intimate friendship, to come into my house, where I am surrounded
  • with my servants, I rest assured that he is not to stab me before he
  • leaves it in order to rob me of my silver standish; and I no more
  • suspect this event than the falling of the house itself, which is new,
  • and solidly built and founded._--But he may have been seized with a
  • sudden and unknown frenzy.--_So may a sudden earthquake arise, and shake
  • and tumble my house about my ears. I shall therefore change the
  • suppositions. I shall say that I know with certainty that he is not to
  • put his hand into the fire and hold it there till it be consumed: And
  • this event, I think I can foretell with the same assurance, as that, if
  • he throw himself out at the window, and meet with no obstruction, he
  • will not remain a moment suspended in the air. No suspicion of an
  • unknown frenzy can give the least possibility to the former event, which
  • is so contrary to all the known principles of human nature. A man who at
  • noon leaves his purse full of gold on the pavement at Charing-Cross, may
  • as well expect that it will fly away like a feather, as that he will
  • find it untouched an hour after. Above one half of human reasonings
  • contain inferences of a similar nature, attended with more or less
  • degrees of certainty proportioned to our experience of the usual conduct
  • of mankind in such particular situations.
  • 71. I have frequently considered, what could possibly be the reason why
  • all mankind, though they have ever, without hesitation, acknowledged the
  • doctrine of necessity in their whole practice and reasoning, have yet
  • discovered such a reluctance to acknowledge it in words, and have rather
  • shown a propensity, in all ages, to profess the contrary opinion. The
  • matter, I think, may be accounted for after the following manner. If we
  • examine the operations of body, and the production of effects from their
  • causes, we shall find that all our faculties can never carry us farther
  • in our knowledge of this relation than barely to observe that particular
  • objects are _constantly conjoined_ together, and that the mind is
  • carried, by a _customary transition,_ from the appearance of one to the
  • belief of the other. But though this conclusion concerning human
  • ignorance be the result of the strictest scrutiny of this subject, men
  • still entertain a strong propensity to believe that they penetrate
  • farther into the powers of nature, and perceive something like a
  • necessary connexion between the cause and the effect. When again they
  • turn their reflections towards the operations of their own minds, and
  • _feel_ no such connexion of the motive and the action; they are thence
  • apt to suppose, that there is a difference between the effects which
  • result from material force, and those which arise from thought and
  • intelligence. But being once convinced that we know nothing farther of
  • causation of any kind than merely the _constant conjunction_ of objects,
  • and the consequent _inference_ of the mind from one to another, and
  • finding that these two circumstances are universally allowed to have
  • place in voluntary actions; we may be more easily led to own the same
  • necessity common to all causes. And though this reasoning may contradict
  • the systems of many philosophers, in ascribing necessity to the
  • determinations of the will, we shall find, upon reflection, that they
  • dissent from it in words only, not in their real sentiment. Necessity,
  • according to the sense in which it is here taken, has never yet been
  • rejected, nor can ever, I think, be rejected by any philosopher. It may
  • only, perhaps, be pretended that the mind can perceive, in the
  • operations of matter, some farther connexion between the cause and
  • effect; and connexion that has not place in voluntary actions of
  • intelligent beings. Now whether it be so or not, can only appear upon
  • examination; and it is incumbent on these philosophers to make good
  • their assertion, by defining or describing that necessity, and pointing
  • it out to us in the operations of material causes.
  • 72. It would seem, indeed, that men begin at the wrong end of this
  • question concerning liberty and necessity, when they enter upon it by
  • examining the faculties of the soul, the influence of the understanding,
  • and the operations of the will. Let them first discuss a more simple
  • question, namely, the operations of body and of brute unintelligent
  • matter; and try whether they can there form any idea of causation and
  • necessity, except that of a constant conjunction of objects, and
  • subsequent inference of the mind from one to another. If these
  • circumstances form, in reality, the whole of that necessity, which we
  • conceive in matter, and if these circumstances be also universally
  • acknowledged to take place in the operations of the mind, the dispute is
  • at an end; at least, must be owned to be thenceforth merely verbal. But
  • as long as we will rashly suppose, that we have some farther idea of
  • necessity and causation in the operations of external objects; at the
  • same time, that we can find nothing farther in the voluntary actions of
  • the mind; there is no possibility of bringing the question to any
  • determinate issue, while we proceed upon so erroneous a supposition. The
  • only method of undeceiving us is to mount up higher; to examine the
  • narrow extent of science when applied to material causes; and to
  • convince ourselves that all we know of them is the constant conjunction
  • and inference above mentioned. We may, perhaps, find that it is with
  • difficulty we are induced to fix such narrow limits to human
  • understanding: But we can afterwards find no difficulty when we come to
  • apply this doctrine to the actions of the will. For as it is evident
  • that these have a regular conjunction with motives and circumstances and
  • characters, and as we always draw inferences from one to the other, we
  • must be obliged to acknowledge in words that necessity, which we have
  • already avowed, in every deliberation of our lives, and in every step of
  • our conduct and behaviour.[17]
  • [17] The prevalence of the doctrine of liberty may be accounted
  • for, from another cause, viz. a false sensation or seeming
  • experience which we have, or may have, of liberty or
  • indifference, in many of our actions. The necessity of any
  • action, whether of matter or of mind, is not, properly
  • speaking, a quality in the agent, but in any thinking or
  • intelligent being, who may consider the action; and it consists
  • chiefly in the determination of his thoughts to infer the
  • existence of that action from some preceding objects; as
  • liberty, when opposed to necessity, is nothing but the want of
  • that determination, and a certain looseness or indifference,
  • which we feel, in passing, or not passing, from the idea of one
  • object to that of any succeeding one. Now we may observe,
  • that, though, in _reflecting_ on human actions, we seldom feel
  • such a looseness, or indifference, but are commonly able to
  • infer them with considerable certainty from their motives, and
  • from the dispositions of the agent; yet it frequently happens,
  • that, in _performing_ the actions themselves, we are sensible
  • of something like it: And as all resembling objects are readily
  • taken for each other, this has been employed as a demonstrative
  • and even intuitive proof of human liberty. We feel, that our
  • actions are subject to our will, on most occasions; and imagine
  • we feel, that the will itself is subject to nothing, because,
  • when by a denial of it we are provoked to try, we feel, that it
  • moves easily every way, and produces an image of itself (or a
  • _Velleïty,_ as it is called in the schools) even on that side,
  • on which it did not settle. This image, or faint motion, we
  • persuade ourselves, could, at that time, have been compleated
  • into the thing itself; because, should that be denied, we find,
  • upon a second trial, that, at present, it can. We consider not,
  • that the fantastical desire of shewing liberty, is here the
  • motive of our actions. And it seems certain, that, however we
  • may imagine we feel a liberty within ourselves, a spectator can
  • commonly infer our actions from our motives and character; and
  • even where he cannot, he concludes in general, that he might,
  • were he perfectly acquainted with every circumstance of our
  • situation and temper, and the most secret springs of our
  • complexion and disposition. Now this is the very essence of
  • necessity, according to the foregoing doctrine.
  • 73. But to proceed in this reconciling project with regard to the
  • question of liberty and necessity; the most contentious question of
  • metaphysics, the most contentious science; it will not require many
  • words to prove, that all mankind have ever agreed in the doctrine of
  • liberty as well as in that of necessity, and that the whole dispute, in
  • this respect also, has been hitherto merely verbal. For what is meant by
  • liberty, when applied to voluntary actions? We cannot surely mean that
  • actions have so little connexion with motives, inclinations, and
  • circumstances, that one does not follow with a certain degree of
  • uniformity from the other, and that one affords no inference by which we
  • can conclude the existence of the other. For these are plain and
  • acknowledged matters of fact. By liberty, then, we can only mean _a
  • power of acting or not acting, according to the determinations of the
  • will;_ that is, if we choose to remain at rest, we may; if we choose to
  • move, we also may. Now this hypothetical liberty is universally allowed
  • to belong to every one who is not a prisoner and in chains. Here, then,
  • is no subject of dispute.
  • 74. Whatever definition we may give of liberty, we should be careful to
  • observe two requisite circumstances; _first,_ that it be consistent with
  • plain matter of fact; _secondly,_ that it be consistent with itself. If
  • we observe these circumstances, and render our definition intelligible,
  • I am persuaded that all mankind will be found of one opinion with
  • regard to it.
  • It is universally allowed that nothing exists without a cause of its
  • existence, and that chance, when strictly examined, is a mere negative
  • word, and means not any real power which has anywhere a being in nature.
  • But it is pretended that some causes are necessary, some not necessary.
  • Here then is the advantage of definitions. Let any one _define_ a cause,
  • without comprehending, as a part of the definition, a _necessary
  • connexion_ with its effect; and let him show distinctly the origin of
  • the idea, expressed by the definition; and I shall readily give up the
  • whole controversy. But if the foregoing explication of the matter be
  • received, this must be absolutely impracticable. Had not objects a
  • regular conjunction with each other, we should never have entertained
  • any notion of cause and effect; and this regular conjunction produces
  • that inference of the understanding, which is the only connexion, that
  • we can have any comprehension of. Whoever attempts a definition of
  • cause, exclusive of these circumstances, will be obliged either to
  • employ unintelligible terms or such as are synonymous to the term which
  • he endeavours to define.[18] And if the definition above mentioned be
  • admitted; liberty, when opposed to necessity, not to constraint, is the
  • same thing with chance; which is universally allowed to have no
  • existence.
  • [18] Thus, if a cause be defined, _that which produces any
  • thing;_ it is easy to observe, that _producing_ is synonymous
  • to _causing._ In like manner, if a cause be defined, _that by
  • which any thing exists;_ this is liable to the same objection.
  • For what is meant by these words, _by which?_ Had it been said,
  • that a cause is _that_ after which _any thing constantly
  • exists;_ we should have understood the terms. For this is,
  • indeed, all we know of the matter. And this constancy forms the
  • very essence of necessity, nor have we any other idea of it.
  • PART II.
  • 75. There is no method of reasoning more common, and yet none more
  • blameable, than, in philosophical disputes, to endeavour the refutation
  • of any hypothesis, by a pretence of its dangerous consequences to
  • religion and morality. When any opinion leads to absurdities, it is
  • certainly false; but it is not certain that an opinion is false, because
  • it is of dangerous consequence. Such topics, therefore, ought entirely
  • to be forborne; as serving nothing to the discovery of truth, but only
  • to make the person of an antagonist odious. This I observe in general,
  • without pretending to draw any advantage from it. I frankly submit to
  • an examination of this kind, and shall venture to affirm that the
  • doctrines, both of necessity and of liberty, as above explained, are not
  • only consistent with morality, but are absolutely essential to
  • its support.
  • Necessity may be defined two ways, conformably to the two definitions of
  • _cause_, of which it makes an essential part. It consists either in the
  • constant conjunction of like objects, or in the inference of the
  • understanding from one object to another. Now necessity, in both these
  • senses, (which, indeed, are at bottom the same) has universally, though
  • tacitly, in the schools, in the pulpit, and in common life, been allowed
  • to belong to the will of man; and no one has ever pretended to deny that
  • we can draw inferences concerning human actions, and that those
  • inferences are founded on the experienced union of like actions, with
  • like motives, inclinations, and circumstances. The only particular in
  • which any one can differ, is, that either, perhaps, he will refuse to
  • give the name of necessity to this property of human actions: But as
  • long as the meaning is understood, I hope the word can do no harm: Or
  • that he will maintain it possible to discover something farther in the
  • operations of matter. But this, it must be acknowledged, can be of no
  • consequence to morality or religion, whatever it may be to natural
  • philosophy or metaphysics. We may here be mistaken in asserting that
  • there is no idea of any other necessity or connexion in the actions of
  • body: But surely we ascribe nothing to the actions of the mind, but what
  • everyone does, and must readily allow of. We change no circumstance in
  • the received orthodox system with regard to the will, but only in that
  • with regard to material objects and causes. Nothing, therefore, can be
  • more innocent, at least, than this doctrine.
  • 76. All laws being founded on rewards and punishments, it is supposed as
  • a fundamental principle, that these motives have a regular and uniform
  • influence on the mind, and both produce the good and prevent the evil
  • actions. We may give to this influence what name we please; but, as it
  • is usually conjoined with the action, it must be esteemed a _cause_, and
  • be looked upon as an instance of that necessity, which we would here
  • establish.
  • The only proper object of hatred or vengeance is a person or creature,
  • endowed with thought and consciousness; and when any criminal or
  • injurious actions excite that passion, it is only by their relation to
  • the person, or connexion with him. Actions are, by their very nature,
  • temporary and perishing; and where they proceed not from some _cause_ in
  • the character and disposition of the person who performed them, they can
  • neither redound to his honour, if good; nor infamy, if evil. The actions
  • themselves may be blameable; they may be contrary to all the rules of
  • morality and religion: But the person is not answerable for them; and as
  • they proceeded from nothing in him that is durable and constant, and
  • leave nothing of that nature behind them, it is impossible he can, upon
  • their account, become the object of punishment or vengeance. According
  • to the principle, therefore, which denies necessity, and consequently
  • causes, a man is as pure and untainted, after having committed the most
  • horrid crime, as at the first moment of his birth, nor is his character
  • anywise concerned in his actions, since they are not derived from it,
  • and the wickedness of the one can never be used as a proof of the
  • depravity of the other.
  • Men are not blamed for such actions as they perform ignorantly and
  • casually, whatever may be the consequences. Why? but because the
  • principles of these actions are only momentary, and terminate in them
  • alone. Men are less blamed for such actions as they perform hastily and
  • unpremeditately than for such as proceed from deliberation. For what
  • reason? but because a hasty temper, though a constant cause or
  • principle in the mind, operates only by intervals, and infects not the
  • whole character. Again, repentance wipes off every crime, if attended
  • with a reformation of life and manners. How is this to be accounted for?
  • but by asserting that actions render a person criminal merely as they
  • are proofs of criminal principles in the mind; and when, by an
  • alteration of these principles, they cease to be just proofs, they
  • likewise cease to be criminal. But, except upon the doctrine of
  • necessity, they never were just proofs, and consequently never
  • were criminal.
  • 77. It will be equally easy to prove, and from the same arguments, that
  • _liberty_, according to that definition above mentioned, in which all
  • men agree, is also essential to morality, and that no human actions,
  • where it is wanting, are susceptible of any moral qualities, or can be
  • the objects either of approbation or dislike. For as actions are objects
  • of our moral sentiment, so far only as they are indications of the
  • internal character, passions, and affections; it is impossible that they
  • can give rise either to praise or blame, where they proceed not from
  • these principles, but are derived altogether from external violence.
  • 78. I pretend not to have obviated or removed all objections to this
  • theory, with regard to necessity and liberty. I can foresee other
  • objections, derived from topics which have not here been treated of. It
  • may be said, for instance, that, if voluntary actions be subjected to
  • the same laws of necessity with the operations of matter, there is a
  • continued chain of necessary causes, pre-ordained and pre-determined,
  • reaching from the original cause of all to every single volition of
  • every human creature. No contingency anywhere in the universe; no
  • indifference; no liberty. While we act, we are, at the same time, acted
  • upon. The ultimate Author of all our volitions is the Creator of the
  • world, who first bestowed motion on this immense machine, and placed all
  • beings in that particular position, whence every subsequent event, by
  • an inevitable necessity, must result. Human actions, therefore, either
  • can have no moral turpitude at all, as proceeding from so good a cause;
  • or if they have any turpitude, they must involve our Creator in the same
  • guilt, while he is acknowledged to be their ultimate cause and author.
  • For as a man, who fired a mine, is answerable for all the consequences
  • whether the train he employed be long or short; so wherever a continued
  • chain of necessary causes is fixed, that Being, either finite or
  • infinite, who produces the first, is likewise the author of all the
  • rest, and must both bear the blame and acquire the praise which belong
  • to them. Our clear and unalterable ideas of morality establish this
  • rule, upon unquestionable reasons, when we examine the consequences of
  • any human action; and these reasons must still have greater force when
  • applied to the volitions and intentions of a Being infinitely wise and
  • powerful. Ignorance or impotence may be pleaded for so limited a
  • creature as man; but those imperfections have no place in our Creator.
  • He foresaw, he ordained, he intended all those actions of men, which we
  • so rashly pronounce criminal. And we must therefore conclude, either
  • that they are not criminal, or that the Deity, not man, is accountable
  • for them. But as either of these positions is absurd and impious, it
  • follows, that the doctrine from which they are deduced cannot possibly
  • be true, as being liable to all the same objections. An absurd
  • consequence, if necessary, proves the original doctrine to be absurd; in
  • the same manner as criminal actions render criminal the original cause,
  • if the connexion between them be necessary and evitable.
  • This objection consists of two parts, which we shall examine separately;
  • _First_, that, if human actions can be traced up, by a necessary chain,
  • to the Deity, they can never be criminal; on account of the infinite
  • perfection of that Being from whom they are derived, and who can intend
  • nothing but what is altogether good and laudable. Or, _Secondly_, if
  • they be criminal, we must retract the attribute of perfection, which we
  • ascribe to the Deity, and must acknowledge him to be the ultimate author
  • of guilt and moral turpitude in all his creatures.
  • 79. The answer to the first objection seems obvious and convincing.
  • There are many philosophers who, after an exact scrutiny of all the
  • phenomena of nature, conclude, that the WHOLE, considered as one system,
  • is, in every period of its existence, ordered with perfect benevolence;
  • and that the utmost possible happiness will, in the end, result to all
  • created beings, without any mixture of positive or absolute ill or
  • misery. Every physical ill, say they, makes an essential part of this
  • benevolent system, and could not possibly be removed, even by the Deity
  • himself, considered as a wise agent, without giving entrance to greater
  • ill, or excluding greater good, which will result from it. From this
  • theory, some philosophers, and the ancient _Stoics_ among the rest,
  • derived a topic of consolation under all afflictions, while they taught
  • their pupils that those ills under which they laboured were, in reality,
  • goods to the universe; and that to an enlarged view, which could
  • comprehend the whole system of nature, every event became an object of
  • joy and exultation. But though this topic be specious and sublime, it
  • was soon found in practice weak and ineffectual. You would surely more
  • irritate than appease a man lying under the racking pains of the gout by
  • preaching up to him the rectitude of those general laws, which produced
  • the malignant humours in his body, and led them through the proper
  • canals, to the sinews and nerves, where they now excite such acute
  • torments. These enlarged views may, for a moment, please the imagination
  • of a speculative man, who is placed in ease and security; but neither
  • can they dwell with constancy on his mind, even though undisturbed by
  • the emotions of pain or passion; much less can they maintain their
  • ground when attacked by such powerful antagonists. The affections take a
  • narrower and more natural survey of their object; and by an economy,
  • more suitable to the infirmity of human minds, regard alone the beings
  • around us, and are actuated by such events as appear good or ill to the
  • private system.
  • 80. The case is the same with _moral_ as with _physical_ ill. It cannot
  • reasonably be supposed, that those remote considerations, which are
  • found of so little efficacy with regard to one, will have a more
  • powerful influence with regard to the other. The mind of man is so
  • formed by nature that, upon the appearance of certain characters,
  • dispositions, and actions, it immediately feels the sentiment of
  • approbation or blame; nor are there any emotions more essential to its
  • frame and constitution. The characters which engage our approbation are
  • chiefly such as contribute to the peace and security of human society;
  • as the characters which excite blame are chiefly such as tend to public
  • detriment and disturbance: Whence it may reasonably be presumed, that
  • the moral sentiments arise, either mediately or immediately, from a
  • reflection of these opposite interests. What though philosophical
  • meditations establish a different opinion or conjecture; that everything
  • is right with regard to the WHOLE, and that the qualities, which disturb
  • society, are, in the main, as beneficial, and are as suitable to the
  • primary intention of nature as those which more directly promote its
  • happiness and welfare? Are such remote and uncertain speculations able
  • to counterbalance the sentiments which arise from the natural and
  • immediate view of the objects? A man who is robbed of a considerable
  • sum; does he find his vexation for the loss anywise diminished by these
  • sublime reflections? Why then should his moral resentment against the
  • crime be supposed incompatible with them? Or why should not the
  • acknowledgment of a real distinction between vice and virtue be
  • reconcileable to all speculative systems of philosophy, as well as that
  • of a real distinction between personal beauty and deformity? Both these
  • distinctions are founded in the natural sentiments of the human mind:
  • And these sentiments are not to be controuled or altered by any
  • philosophical theory or speculation whatsoever.
  • 81. The _second_ objection admits not of so easy and satisfactory an
  • answer; nor is it possible to explain distinctly, how the Deity can be
  • the mediate cause of all the actions of men, without being the author of
  • sin and moral turpitude. These are mysteries, which mere natural and
  • unassisted reason is very unfit to handle; and whatever system she
  • embraces, she must find herself involved in inextricable difficulties,
  • and even contradictions, at every step which she takes with regard to
  • such subjects. To reconcile the indifference and contingency of human
  • actions with prescience; or to defend absolute decrees, and yet free the
  • Deity from being the author of sin, has been found hitherto to exceed
  • all the power of philosophy. Happy, if she be thence sensible of her
  • temerity, when she pries into these sublime mysteries; and leaving a
  • scene so full of obscurities and perplexities, return, with suitable
  • modesty, to her true and proper province, the examination of common
  • life; where she will find difficulties enough to employ her enquiries,
  • without launching into so boundless an ocean of doubt, uncertainty, and
  • contradiction!
  • SECTION IX.
  • OF THE REASON OF ANIMALS.
  • 82. All our reasonings concerning matter of fact are founded on a
  • species of Analogy, which leads us to expect from any cause the same
  • events, which we have observed to result from similar causes. Where the
  • causes are entirely similar, the analogy is perfect, and the inference,
  • drawn from it, is regarded as certain and conclusive: nor does any man
  • ever entertain a doubt, where he sees a piece of iron, that it will have
  • weight and cohesion of parts; as in all other instances, which have ever
  • fallen under his observation. But where the objects have not so exact a
  • similarity, the analogy is less perfect, and the inference is less
  • conclusive; though still it has some force, in proportion to the degree
  • of similarity and resemblance. The anatomical observations, formed upon
  • one animal, are, by this species of reasoning, extended to all animals;
  • and it is certain, that when the circulation of the blood, for instance,
  • is clearly proved to have place in one creature, as a frog, or fish, it
  • forms a strong presumption, that the same principle has place in all.
  • These analogical observations may be carried farther, even to this
  • science, of which we are now treating; and any theory, by which we
  • explain the operations of the understanding, or the origin and connexion
  • of the passions in man, will acquire additional authority, if we find,
  • that the same theory is requisite to explain the same phenomena in all
  • other animals. We shall make trial of this, with regard to the
  • hypothesis, by which we have, in the foregoing discourse, endeavoured
  • to account for all experimental reasonings; and it is hoped, that this
  • new point of view will serve to confirm all our former observations.
  • 83. _First_, It seems evident, that animals as well as men learn many
  • things from experience, and infer, that the same events will always
  • follow from the same causes. By this principle they become acquainted
  • with the more obvious properties of external objects, and gradually,
  • from their birth, treasure up a knowledge of the nature of fire, water,
  • earth, stones, heights, depths, &c., and of the effects which result
  • from their operation. The ignorance and inexperience of the young are
  • here plainly distinguishable from the cunning and sagacity of the old,
  • who have learned, by long observation, to avoid what hurt them, and to
  • pursue what gave ease or pleasure. A horse, that has been accustomed to
  • the field, becomes acquainted with the proper height which he can leap,
  • and will never attempt what exceeds his force and ability. An old
  • greyhound will trust the more fatiguing part of the chace to the
  • younger, and will place himself so as to meet the hare in her doubles;
  • nor are the conjectures, which he forms on this occasion, founded in any
  • thing but his observation and experience.
  • This is still more evident from the effects of discipline and education
  • on animals, who, by the proper application of rewards and punishments,
  • may be taught any course of action, and most contrary to their natural
  • instincts and propensities. Is it not experience, which renders a dog
  • apprehensive of pain, when you menace him, or lift up the whip to beat
  • him? Is it not even experience, which makes him answer to his name, and
  • infer, from such an arbitrary sound, that you mean him rather than any
  • of his fellows, and intend to call him, when you pronounce it in a
  • certain manner, and with a certain tone and accent?
  • In all these cases, we may observe, that the animal infers some fact
  • beyond what immediately strikes his senses; and that this inference is
  • altogether founded on past experience, while the creature expects from
  • the present object the same consequences, which it has always found in
  • its observation to result from similar objects.
  • 84. _Secondly_, It is impossible, that this inference of the animal can
  • be founded on any process of argument or reasoning, by which he
  • concludes, that like events must follow like objects, and that the
  • course of nature will always be regular in its operations. For if there
  • be in reality any arguments of this nature, they surely lie too abstruse
  • for the observation of such imperfect understandings; since it may well
  • employ the utmost care and attention of a philosophic genius to discover
  • and observe them. Animals, therefore, are not guided in these inferences
  • by reasoning: Neither are children: Neither are the generality of
  • mankind, in their ordinary actions and conclusions: Neither are
  • philosophers themselves, who, in all the active parts of life, are, in
  • the main, the same with the vulgar, and are governed by the same maxims.
  • Nature must have provided some other principle, of more ready, and more
  • general use and application; nor can an operation of such immense
  • consequence in life, as that of inferring effects from causes, be
  • trusted to the uncertain process of reasoning and argumentation. Were
  • this doubtful with regard to men, it seems to admit of no question with
  • regard to the brute creation; and the conclusion being once firmly
  • established in the one, we have a strong presumption, from all the rules
  • of analogy, that it ought to be universally admitted, without any
  • exception or reserve. It is custom alone, which engages animals, from
  • every object, that strikes their senses, to infer its usual attendant,
  • and carries their imagination, from the appearance of the one, to
  • conceive the other, in that particular manner, which we denominate
  • _belief_. No other explication can be given of this operation, in all
  • the higher, as well as lower classes of sensitive beings, which fall
  • under our notice and observation [19].
  • [19] Since all reasonings concerning facts or causes is derived
  • merely from custom, it may be asked how it happens, that men so
  • much surpass animals in reasoning, and one man so much
  • surpasses another? Has not the same custom the same
  • influence on all?
  • We shall here endeavour briefly to explain the great difference
  • in human understandings: After which the reason of the
  • difference between men and animals will easily be comprehended.
  • 1. When we have lived any time, and have been accustomed to the
  • uniformity of nature, we acquire a general habit, by which we
  • always transfer the known to the unknown, and conceive the
  • latter to resemble the former. By means of this general
  • habitual principle, we regard even one experiment as the
  • foundation of reasoning, and expect a similar event with some
  • degree of certainty, where the experiment has been made
  • accurately, and free from all foreign circumstances. It is
  • therefore considered as a matter of great importance to observe
  • the consequences of things; and as one man may very much
  • surpass another in attention and memory and observation, this
  • will make a very great difference in their reasoning.
  • 2. Where there is a complication of causes to produce any
  • effect, one mind may be much larger than another, and better
  • able to comprehend the whole system of objects, and to infer
  • justly their consequences.
  • 3. One man is able to carry on a chain of consequences to a
  • greater length than another.
  • 4. Few men can think long without running into a confusion of
  • ideas, and mistaking one for another; and there are various
  • degrees of this infirmity.
  • 5. The circumstance, on which the effect depends, is frequently
  • involved in other circumstances, which are foreign and
  • extrinsic. The separation of it often requires great attention,
  • accuracy, and subtilty.
  • 6. The forming of general maxims from particular observation is
  • a very nice operation; and nothing is more usual, from haste or
  • a narrowness of mind, which sees not on all sides, than to
  • commit mistakes in this particular.
  • 7. When we reason from analogies, the man, who has the greater
  • experience or the greater promptitude of suggesting analogies,
  • will be the better reasoner.
  • 8. Byasses from prejudice, education, passion, party, &c. hang
  • more upon one mind than another.
  • 9. After we have acquired a confidence in human testimony,
  • books and conversation enlarge much more the sphere of one
  • man's experience and thought than those of another.
  • It would be easy to discover many other circumstances that make
  • a difference in the understandings of men.
  • 85. But though animals learn many parts of their knowledge from
  • observation, there are also many parts of it, which they derive from the
  • original hand of nature; which much exceed the share of capacity they
  • possess on ordinary occasions; and in which they improve, little or
  • nothing, by the longest practice and experience. These we denominate
  • Instincts, and are so apt to admire as something very extraordinary, and
  • inexplicable by all the disquisitions of human understanding. But our
  • wonder will, perhaps, cease or diminish, when we consider, that the
  • experimental reasoning itself, which we possess in common with beasts,
  • and on which the whole conduct of life depends, is nothing but a species
  • of instinct or mechanical power, that acts in us unknown to ourselves;
  • and in its chief operations, is not directed by any such relations or
  • comparisons of ideas, as are the proper objects of our intellectual
  • faculties. Though the instinct be different, yet still it is an
  • instinct, which teaches a man to avoid the fire; as much as that, which
  • teaches a bird, with such exactness, the art of incubation, and the
  • whole economy and order of its nursery.
  • SECTION X.
  • OF MIRACLES.
  • PART I.
  • 86. There is, in Dr. Tillotson's writings, an argument against the _real
  • presence_, which is as concise, and elegant, and strong as any argument
  • can possibly be supposed against a doctrine, so little worthy of a
  • serious refutation. It is acknowledged on all hands, says that learned
  • prelate, that the authority, either of the scripture or of tradition, is
  • founded merely in the testimony of the apostles, who were eye-witnesses
  • to those miracles of our Saviour, by which he proved his divine mission.
  • Our evidence, then, for the truth of the _Christian_ religion is less
  • than the evidence for the truth of our senses; because, even in the
  • first authors of our religion, it was no greater; and it is evident it
  • must diminish in passing from them to their disciples; nor can any one
  • rest such confidence in their testimony, as in the immediate object of
  • his senses. But a weaker evidence can never destroy a stronger; and
  • therefore, were the doctrine of the real presence ever so clearly
  • revealed in scripture, it were directly contrary to the rules of just
  • reasoning to give our assent to it. It contradicts sense, though both
  • the scripture and tradition, on which it is supposed to be built, carry
  • not such evidence with them as sense; when they are considered merely as
  • external evidences, and are not brought home to every one's breast, by
  • the immediate operation of the Holy Spirit.
  • Nothing is so convenient as a decisive argument of this kind, which
  • must at least _silence_ the most arrogant bigotry and superstition, and
  • free us from their impertinent solicitations. I flatter myself, that I
  • have discovered an argument of a like nature, which, if just, will, with
  • the wise and learned, be an everlasting check to all kinds of
  • superstitious delusion, and consequently, will be useful as long as the
  • world endures. For so long, I presume, will the accounts of miracles and
  • prodigies be found in all history, sacred and profane.
  • 87. Though experience be our only guide in reasoning concerning matters
  • of fact; it must be acknowledged, that this guide is not altogether
  • infallible, but in some cases is apt to lead us into errors. One, who in
  • our climate, should expect better weather in any week of June than in
  • one of December, would reason justly, and conformably to experience; but
  • it is certain, that he may happen, in the event, to find himself
  • mistaken. However, we may observe, that, in such a case, he would have
  • no cause to complain of experience; because it commonly informs us
  • beforehand of the uncertainty, by that contrariety of events, which we
  • may learn from a diligent observation. All effects follow not with like
  • certainty from their supposed causes. Some events are found, in all
  • countries and all ages, to have been constantly conjoined together:
  • Others are found to have been more variable, and sometimes to disappoint
  • our expectations; so that, in our reasonings concerning matter of fact,
  • there are all imaginable degrees of assurance, from the highest
  • certainty to the lowest species of moral evidence.
  • A wise man, therefore, proportions his belief to the evidence. In such
  • conclusions as are founded on an infallible experience, he expects the
  • event with the last degree of assurance, and regards his past experience
  • as a full _proof_ of the future existence of that event. In other
  • cases, he proceeds with more caution: He weighs the opposite
  • experiments: He considers which side is supported by the greater number
  • of experiments: to that side he inclines, with doubt and hesitation; and
  • when at last he fixes his judgement, the evidence exceeds not what we
  • properly call _probability_. All probability, then, supposes an
  • opposition of experiments and observations, where the one side is found
  • to overbalance the other, and to produce a degree of evidence,
  • proportioned to the superiority. A hundred instances or experiments on
  • one side, and fifty on another, afford a doubtful expectation of any
  • event; though a hundred uniform experiments, with only one that is
  • contradictory, reasonably beget a pretty strong degree of assurance. In
  • all cases, we must balance the opposite experiments, where they are
  • opposite, and deduct the smaller number from the greater, in order to
  • know the exact force of the superior evidence.
  • 88. To apply these principles to a particular instance; we may observe,
  • that there is no species of reasoning more common, more useful, and even
  • necessary to human life, than that which is derived from the testimony
  • of men, and the reports of eye-witnesses and spectators. This species of
  • reasoning, perhaps, one may deny to be founded on the relation of cause
  • and effect. I shall not dispute about a word. It will be sufficient to
  • observe that our assurance in any argument of this kind is derived from
  • no other principle than our observation of the veracity of human
  • testimony, and of the usual conformity of facts to the reports of
  • witnesses. It being a general maxim, that no objects have any
  • discoverable connexion together, and that all the inferences, which we
  • can draw from one to another, are founded merely on our experience of
  • their constant and regular conjunction; it is evident, that we ought not
  • to make an exception to this maxim in favour of human testimony, whose
  • connexion with any event seems, in itself, as little necessary as any
  • other. Were not the memory tenacious to a certain degree, had not men
  • commonly an inclination to truth and a principle of probity; were they
  • not sensible to shame, when detected in a falsehood: Were not these, I
  • say, discovered by experience to be qualities, inherent in human nature,
  • we should never repose the least confidence in human testimony. A man
  • delirious, or noted for falsehood and villany, has no manner of
  • authority with us.
  • And as the evidence, derived from witnesses and human testimony, is
  • founded on past experience, so it varies with the experience, and is
  • regarded either as a _proof_ or a _probability_, according as the
  • conjunction between any particular kind of report and any kind of object
  • has been found to be constant or variable. There are a number of
  • circumstances to be taken into consideration in all judgements of this
  • kind; and the ultimate standard, by which we determine all disputes,
  • that may arise concerning them, is always derived from experience and
  • observation. Where this experience is not entirely uniform on any side,
  • it is attended with an unavoidable contrariety in our judgements, and
  • with the same opposition and mutual destruction of argument as in every
  • other kind of evidence. We frequently hesitate concerning the reports of
  • others. We balance the opposite circumstances, which cause any doubt or
  • uncertainty; and when we discover a superiority on any side, we incline
  • to it; but still with a diminution of assurance, in proportion to the
  • force of its antagonist.
  • 89. This contrariety of evidence, in the present case, may be derived
  • from several different causes; from the opposition of contrary
  • testimony; from the character or number of the witnesses; from the
  • manner of their delivering their testimony; or from the union of all
  • these circumstances. We entertain a suspicion concerning any matter of
  • fact, when the witnesses contradict each other; when they are but few,
  • or of a doubtful character; when they have an interest in what they
  • affirm; when they deliver their testimony with hesitation, or on the
  • contrary, with too violent asseverations. There are many other
  • particulars of the same kind, which may diminish or destroy the force of
  • any argument, derived from human testimony.
  • Suppose, for instance, that the fact, which the testimony endeavours to
  • establish, partakes of the extraordinary and the marvellous; in that
  • case, the evidence, resulting from the testimony, admits of a
  • diminution, greater or less, in proportion as the fact is more or less
  • unusual. The reason why we place any credit in witnesses and historians,
  • is not derived from any _connexion_, which we perceive _a priori_,
  • between testimony and reality, but because we are accustomed to find a
  • conformity between them. But when the fact attested is such a one as has
  • seldom fallen under our observation, here is a contest of two opposite
  • experiences; of which the one destroys the other, as far as its force
  • goes, and the superior can only operate on the mind by the force, which
  • remains. The very same principle of experience, which gives us a certain
  • degree of assurance in the testimony of witnesses, gives us also, in
  • this case, another degree of assurance against the fact, which they
  • endeavour to establish; from which contradition there necessarily arises
  • a counterpoize, and mutual destruction of belief and authority.
  • _I should not believe such a story were it told me by Cato_, was a
  • proverbial saying in Rome, even during the lifetime of that
  • philosophical patriot.[20] The incredibility of a fact, it was allowed,
  • might invalidate so great an authority.
  • [20] Plutarch, in vita Catonis.
  • The Indian prince, who refused to believe the first relations concerning
  • the effects of frost, reasoned justly; and it naturally required very
  • strong testimony to engage his assent to facts, that arose from a state
  • of nature, with which he was unacquainted, and which bore so little
  • analogy to those events, of which he had had constant and uniform
  • experience. Though they were not contrary to his experience, they were
  • not conformable to it.[21]
  • [21] No Indian, it is evident, could have experience that water
  • did not freeze in cold climates. This is placing nature in a
  • situation quite unknown to him; and it is impossible for him to
  • tell _a priori _what will result from it. It is making a new
  • experiment, the consequence of which is always uncertain. One
  • may sometimes conjecture from analogy what will follow; but
  • still this is but conjecture. And it must be confessed, that,
  • in the present case of freezing, the event follows contrary to
  • the rules of analogy, and is such as a rational Indian would
  • not look for. The operations of cold upon water are not
  • gradual, according to the degrees of cold; but whenever it
  • comes to the freezing point, the water passes in a moment, from
  • the utmost liquidity to perfect hardness. Such an event,
  • therefore, may be denominated _extraordinary_, and requires a
  • pretty strong testimony, to render it credible to people in a
  • warm climate: But still it is not _miraculous_, nor contrary to
  • uniform experience of the course of nature in cases where all
  • the circumstances are the same. The inhabitants of Sumatra
  • have always seen water fluid in their own climate, and the
  • freezing of their rivers ought to be deemed a prodigy: But they
  • never saw water in Muscovy during the winter; and therefore
  • they cannot reasonably be positive what would there be the
  • consequence.
  • 90. But in order to encrease the probability against the testimony of
  • witnesses, let us suppose, that the fact, which they affirm, instead of
  • being only marvellous, is really miraculous; and suppose also, that the
  • testimony considered apart and in itself, amounts to an entire proof; in
  • that case, there is proof against proof, of which the strongest must
  • prevail, but still with a diminution of its force, in proportion to that
  • of its antagonist.
  • A miracle is a violation of the laws of nature; and as a firm and
  • unalterable experience has established these laws, the proof against a
  • miracle, from the very nature of the fact, is as entire as any argument
  • from experience can possibly be imagined. Why is it more than probable,
  • that all men must die; that lead cannot, of itself, remain suspended in
  • the air; that fire consumes wood, and is extinguished by water; unless
  • it be, that these events are found agreeable to the laws of nature, and
  • there is required a violation of these laws, or in other words, a
  • miracle to prevent them? Nothing is esteemed a miracle, if it ever
  • happen in the common course of nature. It is no miracle that a man,
  • seemingly in good health, should die on a sudden: because such a kind of
  • death, though more unusual than any other, has yet been frequently
  • observed to happen. But it is a miracle, that a dead man should come to
  • life; because that has never been observed in any age or country. There
  • must, therefore, be a uniform experience against every miraculous event,
  • otherwise the event would not merit that appellation. And as a uniform
  • experience amounts to a proof, there is here a direct and full _proof_,
  • from the nature of the fact, against the existence of any miracle; nor
  • can such a proof be destroyed, or the miracle rendered credible, but by
  • an opposite proof, which is superior.[22]
  • [22] Sometimes an event may not, _in itself_, seem to be
  • contrary to the laws of nature, and yet, if it were real, it
  • might, by reason of some circumstances, be denominated a
  • miracle; because, in _fact_, it is contrary to these laws. Thus
  • if a person, claiming a divine authority, should command a sick
  • person to be well, a healthful man to fall down dead, the
  • clouds to pour rain, the winds to blow, in short, should order
  • many natural events, which immediately follow upon his command;
  • these might justly be esteemed miracles, because they are
  • really, in this case, contrary to the laws of nature. For if
  • any suspicion remain, that the event and command concurred by
  • accident, there is no miracle and no transgression of the laws
  • of nature. If this suspicion be removed, there is evidently a
  • miracle, and a transgression of these laws; because nothing can
  • be more contrary to nature than that the voice or command of a
  • man should have such an influence. A miracle may be accurately
  • defined, _a transgression of a law of nature by a particular
  • volition of the Deity, or by the interposition of some
  • invisible agent_. A miracle may either be discoverable by men
  • or not. This alters not its nature and essence. The raising of
  • a house or ship into the air is a visible miracle. The raising
  • of a feather, when the wind wants ever so little of a force
  • requisite for that purpose, is as real a miracle, though not so
  • sensible with regard to us.
  • 91. The plain consequence is (and it is a general maxim worthy of our
  • attention), 'That no testimony is sufficient to establish a miracle,
  • unless the testimony be of such a kind, that its falsehood would be more
  • miraculous, than the fact, which it endeavours to establish; and even in
  • that case there is a mutual destruction of arguments, and the superior
  • only gives us an assurance suitable to that degree of force, which
  • remains, after deducting the inferior.' When anyone tells me, that he
  • saw a dead man restored to life, I immediately consider with myself,
  • whether it be more probable, that this person should either deceive or
  • be deceived, or that the fact, which he relates, should really have
  • happened. I weigh the one miracle against the other; and according to
  • the superiority, which I discover, I pronounce my decision, and always
  • reject the greater miracle. If the falsehood of his testimony would be
  • more miraculous, than the event which he relates; then, and not till
  • then, can he pretend to command my belief or opinion.
  • PART II.
  • 92. In the foregoing reasoning we have supposed, that the testimony,
  • upon which a miracle is founded, may possibly amount to an entire proof,
  • and that the falsehood of that testimony would be a real prodigy: But it
  • is easy to shew, that we have been a great deal too liberal in our
  • concession, and that there never was a miraculous event established on
  • so full an evidence.
  • For _first_, there is not to be found, in all history, any miracle
  • attested by a sufficient number of men, of such unquestioned good-sense,
  • education, and learning, as to secure us against all delusion in
  • themselves; of such undoubted integrity, as to place them beyond all
  • suspicion of any design to deceive others; of such credit and reputation
  • in the eyes of mankind, as to have a great deal to lose in case of their
  • being detected in any falsehood; and at the same time, attesting facts
  • performed in such a public manner and in so celebrated a part of the
  • world, as to render the detection unavoidable: All which circumstances
  • are requisite to give us a full assurance in the testimony of men.
  • 93. _Secondly_. We may observe in human nature a principle which, if
  • strictly examined, will be found to diminish extremely the assurance,
  • which we might, from human testimony, have, in any kind of prodigy. The
  • maxim, by which we commonly conduct ourselves in our reasonings, is,
  • that the objects, of which we have no experience, resembles those, of
  • which we have; that what we have found to be most usual is always most
  • probable; and that where there is an opposition of arguments, we ought
  • to give the preference to such as are founded on the greatest number of
  • past observations. But though, in proceeding by this rule, we readily
  • reject any fact which is unusual and incredible in an ordinary degree;
  • yet in advancing farther, the mind observes not always the same rule;
  • but when anything is affirmed utterly absurd and miraculous, it rather
  • the more readily admits of such a fact, upon account of that very
  • circumstance, which ought to destroy all its authority. The passion of
  • _surprise_ and _wonder_, arising from miracles, being an agreeable
  • emotion, gives a sensible tendency towards the belief of those events,
  • from which it is derived. And this goes so far, that even those who
  • cannot enjoy this pleasure immediately, nor can believe those miraculous
  • events, of which they are informed, yet love to partake of the
  • satisfaction at second-hand or by rebound, and place a pride and delight
  • in exciting the admiration of others.
  • With what greediness are the miraculous accounts of travellers received,
  • their descriptions of sea and land monsters, their relations of
  • wonderful adventures, strange men, and uncouth manners? But if the
  • spirit of religion join itself to the love of wonder, there is an end of
  • common sense; and human testimony, in these circumstances, loses all
  • pretensions to authority. A religionist may be an enthusiast, and
  • imagine he sees what has no reality: he may know his narrative to be
  • false, and yet persevere in it, with the best intentions in the world,
  • for the sake of promoting so holy a cause: or even where this delusion
  • has not place, vanity, excited by so strong a temptation, operates on
  • him more powerfully than on the rest of mankind in any other
  • circumstances; and self-interest with equal force. His auditors may not
  • have, and commonly have not, sufficient judgement to canvass his
  • evidence: what judgement they have, they renounce by principle, in these
  • sublime and mysterious subjects: or if they were ever so willing to
  • employ it, passion and a heated imagination disturb the regularity of
  • its operations. Their credulity increases his impudence: and his
  • impudence overpowers their credulity.
  • Eloquence, when at its highest pitch, leaves little room for reason or
  • reflection; but addressing itself entirely to the fancy or the
  • affections, captivates the willing hearers, and subdues their
  • understanding. Happily, this pitch it seldom attains. But what a Tully
  • or a Demosthenes could scarcely effect over a Roman or Athenian
  • audience, every _Capuchin_, every itinerant or stationary teacher can
  • perform over the generality of mankind, and in a higher degree, by
  • touching such gross and vulgar passions.
  • The many instances of forged miracles, and prophecies, and supernatural
  • events, which, in all ages, have either been detected by contrary
  • evidence, or which detect themselves by their absurdity, prove
  • sufficiently the strong propensity of mankind to the extraordinary and
  • the marvellous, and ought reasonably to beget a suspicion against all
  • relations of this kind. This is our natural way of thinking, even with
  • regard to the most common and most credible events. For instance: There
  • is no kind of report which rises so easily, and spreads so quickly,
  • especially in country places and provincial towns, as those concerning
  • marriages; insomuch that two young persons of equal condition never see
  • each other twice, but the whole neighbourhood immediately join them
  • together. The pleasure of telling a piece of news so interesting, of
  • propagating it, and of being the first reporters of it, spreads the
  • intelligence. And this is so well known, that no man of sense gives
  • attention to these reports, till he find them confirmed by some greater
  • evidence. Do not the same passions, and others still stronger, incline
  • the generality of mankind to believe and report, with the greatest
  • vehemence and assurance, all religious miracles?
  • 94. _Thirdly_. It forms a strong presumption against all supernatural
  • and miraculous relations, that they are observed chiefly to abound among
  • ignorant and barbarous nations; or if a civilized people has ever given
  • admission to any of them, that people will be found to have received
  • them from ignorant and barbarous ancestors, who transmitted them with
  • that inviolable sanction and authority, which always attend received
  • opinions. When we peruse the first histories of all nations, we are apt
  • to imagine ourselves transported into some new world; where the whole
  • frame of nature is disjointed, and every element performs its operations
  • in a different manner, from what it does at present. Battles,
  • revolutions, pestilence, famine and death, are never the effect of those
  • natural causes, which we experience. Prodigies, omens, oracles,
  • judgements, quite obscure the few natural events, that are intermingled
  • with them. But as the former grow thinner every page, in proportion as
  • we advance nearer the enlightened ages, we soon learn, that there is
  • nothing mysterious or supernatural in the case, but that all proceeds
  • from the usual propensity of mankind towards the marvellous, and that,
  • though this inclination may at intervals receive a check from sense and
  • learning, it can never be thoroughly extirpated from human nature.
  • _It is strange_, a judicious reader is apt to say, upon the perusal of
  • these wonderful historians, _that such prodigious_ _events never happen
  • in our days_. But it is nothing strange, I hope, that men should lie in
  • all ages. You must surely have seen instances enough of that frailty.
  • You have yourself heard many such marvellous relations started, which,
  • being treated with scorn by all the wise and judicious, have at last
  • been abandoned even by the vulgar. Be assured, that those renowned lies,
  • which have spread and flourished to such a monstrous height, arose from
  • like beginnings; but being sown in a more proper soil, shot up at last
  • into prodigies almost equal to those which they relate.
  • It was a wise policy in that false prophet, Alexander, who though now
  • forgotten, was once so famous, to lay the first scene of his impostures
  • in Paphlagonia, where, as Lucian tells us, the people were extremely
  • ignorant and stupid, and ready to swallow even the grossest delusion.
  • People at a distance, who are weak enough to think the matter at all
  • worth enquiry, have no opportunity of receiving better information. The
  • stories come magnified to them by a hundred circumstances. Fools are
  • industrious in propagating the imposture; while the wise and learned are
  • contented, in general, to deride its absurdity, without informing
  • themselves of the particular facts, by which it may be distinctly
  • refuted. And thus the impostor above mentioned was enabled to proceed,
  • from his ignorant Paphlagonians, to the enlisting of votaries, even
  • among the Grecian philosophers, and men of the most eminent rank and
  • distinction in Rome: nay, could engage the attention of that sage
  • emperor Marcus Aurelius; so far as to make him trust the success of a
  • military expedition to his delusive prophecies.
  • The advantages are so great, of starting an imposture among an ignorant
  • people, that, even though the delusion should be too gross to impose on
  • the generality of them (_which, though seldom, is sometimes the case_)
  • it has a much better chance for succeeding in remote countries, than if
  • the first scene had been laid in a city renowned for arts and
  • knowledge. The most ignorant and barbarous of these barbarians carry
  • the report abroad. None of their countrymen have a large correspondence,
  • or sufficient credit and authority to contradict and beat down the
  • delusion. Men's inclination to the marvellous has full opportunity to
  • display itself. And thus a story, which is universally exploded in the
  • place where it was first started, shall pass for certain at a thousand
  • miles distance. But had Alexander fixed his residence at Athens, the
  • philosophers of that renowned mart of learning had immediately spread,
  • throughout the whole Roman empire, their sense of the matter; which,
  • being supported by so great authority, and displayed by all the force of
  • reason and eloquence, had entirely opened the eyes of mankind. It is
  • true; Lucian, passing by chance through Paphlagonia, had an opportunity
  • of performing this good office. But, though much to be wished, it does
  • not always happen, that every Alexander meets with a Lucian, ready to
  • expose and detect his impostures.
  • 95. I may add as a _fourth_ reason, which diminishes the authority of
  • prodigies, that there is no testimony for any, even those which have not
  • been expressly detected, that is not opposed by an infinite number of
  • witnesses; so that not only the miracle destroys the credit of
  • testimony, but the testimony destroys itself. To make this the better
  • understood, let us consider, that, in matters of religion, whatever is
  • different is contrary; and that it is impossible the religions of
  • ancient Rome, of Turkey, of Siam, and of China should, all of them, be
  • established on any solid foundation. Every miracle, therefore, pretended
  • to have been wrought in any of these religions (and all of them abound
  • in miracles), as its direct scope is to establish the particular system
  • to which it is attributed; so has it the same force, though more
  • indirectly, to overthrow every other system. In destroying a rival
  • system, it likewise destroys the credit of those miracles, on which that
  • system was established; so that all the prodigies of different
  • religions are to be regarded as contrary facts, and the evidences of
  • these prodigies, whether weak or strong, as opposite to each other.
  • According to this method of reasoning, when we believe any miracle of
  • Mahomet or his successors, we have for our warrant the testimony of a
  • few barbarous Arabians: And on the other hand, we are to regard the
  • authority of Titus Livius, Plutarch, Tacitus, and, in short, of all the
  • authors and witnesses, Grecian, Chinese, and Roman Catholic, who have
  • related any miracle in their particular religion; I say, we are to
  • regard their testimony in the same light as if they had mentioned that
  • Mahometan miracle, and had in express terms contradicted it, with the
  • same certainty as they have for the miracle they relate. This argument
  • may appear over subtile and refined; but is not in reality different
  • from the reasoning of a judge, who supposes, that the credit of two
  • witnesses, maintaining a crime against any one, is destroyed by the
  • testimony of two others, who affirm him to have been two hundred leagues
  • distant, at the same instant when the crime is said to have been
  • committed.
  • 96. One of the best attested miracles in all profane history, is that
  • which Tacitus reports of Vespasian, who cured a blind man in Alexandria,
  • by means of his spittle, and a lame man by the mere touch of his foot;
  • in obedience to a vision of the god Serapis, who had enjoined them to
  • have recourse to the Emperor, for these miraculous cures. The story may
  • be seen in that fine historian[23]; where every circumstance seems to add
  • weight to the testimony, and might be displayed at large with all the
  • force of argument and eloquence, if any one were now concerned to
  • enforce the evidence of that exploded and idolatrous superstition. The
  • gravity, solidity, age, and probity of so great an emperor, who, through
  • the whole course of his life, conversed in a familiar manner with his
  • friends and courtiers, and never affected those extraordinary airs of
  • divinity assumed by Alexander and Demetrius. The historian, a
  • cotemporary writer, noted for candour and veracity, and withal, the
  • greatest and most penetrating genius, perhaps, of all antiquity; and so
  • free from any tendency to credulity, that he even lies under the
  • contrary imputation, of atheism and profaneness: The persons, from whose
  • authority he related the miracle, of established character for judgement
  • and veracity, as we may well presume; eye-witnesses of the fact, and
  • confirming their testimony, after the Flavian family was despoiled of
  • the empire, and could no longer give any reward, as the price of a lie.
  • _Utrumque, qui interfuere, nunc quoque memorant, postquam nullum
  • mendacio pretium_. To which if we add the public nature of the facts, as
  • related, it will appear, that no evidence can well be supposed stronger
  • for so gross and so palpable a falsehood.
  • [23] Hist. lib. iv. cap. 81. Suetonius gives nearly the same
  • account _in vita_ Vesp.
  • There is also a memorable story related by Cardinal de Retz, which may
  • well deserve our consideration. When that intriguing politician fled
  • into Spain, to avoid the persecution of his enemies, he passed through
  • Saragossa, the capital of Arragon, where he was shewn, in the cathedral,
  • a man, who had served seven years as a door-keeper, and was well known
  • to every body in town, that had ever paid his devotions at that church.
  • He had been seen, for so long a time, wanting a leg; but recovered that
  • limb by the rubbing of holy oil upon the stump; and the cardinal assures
  • us that he saw him with two legs. This miracle was vouched by all the
  • canons of the church; and the whole company in town were appealed to for
  • a confirmation of the fact; whom the cardinal found, by their zealous
  • devotion, to be thorough believers of the miracle. Here the relater was
  • also cotemporary to the supposed prodigy, of an incredulous and
  • libertine character, as well as of great genius; the miracle of so
  • _singular_ a nature as could scarcely admit of a counterfeit, and the
  • witnesses very numerous, and all of them, in a manner, spectators of the
  • fact, to which they gave their testimony. And what adds mightily to the
  • force of the evidence, and may double our surprise on this occasion, is,
  • that the cardinal himself, who relates the story, seems not to give any
  • credit to it, and consequently cannot be suspected of any concurrence in
  • the holy fraud. He considered justly, that it was not requisite, in
  • order to reject a fact of this nature, to be able accurately to disprove
  • the testimony, and to trace its falsehood, through all the circumstances
  • of knavery and credulity which produced it. He knew, that, as this was
  • commonly altogether impossible at any small distance of time and place;
  • so was it extremely difficult, even where one was immediately present,
  • by reason of the bigotry, ignorance, cunning, and roguery of a great
  • part of mankind. He therefore concluded, like a just reasoner, that such
  • an evidence carried falsehood upon the very face of it, and that a
  • miracle, supported by any human testimony, was more properly a subject
  • of derision than of argument.
  • There surely never was a greater number of miracles ascribed to one
  • person, than those, which were lately said to have been wrought in
  • France upon the tomb of Abbé Paris, the famous Jansenist, with whose
  • sanctity the people were so long deluded. The curing of the sick, giving
  • hearing to the deaf, and sight to the blind, were every where talked of
  • as the usual effects of that holy sepulchre. But what is more
  • extraordinary; many of the miracles were immediately proved upon the
  • spot, before judges of unquestioned integrity, attested by witnesses of
  • credit and distinction, in a learned age, and on the most eminent
  • theatre that is now in the world. Nor is this all: a relation of them
  • was published and dispersed every where; nor were the _Jesuits_, though
  • a learned body, supported by the civil magistrate, and determined
  • enemies to those opinions, in whose favour the miracles were said to
  • have been wrought, ever able distinctly to refute or detect them[24].
  • Where shall we find such a number of circumstances, agreeing to the
  • corroboration of one fact? And what have we to oppose to such a cloud of
  • witnesses, but the absolute impossibility or miraculous nature of the
  • events, which they relate? And this surely, in the eyes of all
  • reasonable people, will alone be regarded as a sufficient refutation.
  • [24] This book was writ by Mons. Montgeron, counsellor or judge
  • of the parliament of Paris, a man of figure and character, who
  • was also a martyr to the cause, and is now said to be somewhere
  • in a dungeon on account of his book.
  • There is another book in three volumes (called _Recueil des
  • Miracles de l'Abbé_ Paris) giving an account of many of these
  • miracles, and accompanied with prefatory discourses, which are
  • very well written. There runs, however, through the whole of
  • these a ridiculous comparison between the miracles of our
  • Saviour and those of the Abbé; wherein it is asserted, that the
  • evidence for the latter is equal to that for the former: As if
  • the testimony of men could ever be put in the balance with that
  • of God himself, who conducted the pen of the inspired writers.
  • If these writers, indeed, were to be considered merely as human
  • testimony, the French author is very moderate in his
  • comparison; since he might, with some appearance of reason,
  • pretend, that the Jansenist miracles much surpass the other in
  • evidence and authority. The following circumstances are drawn
  • from authentic papers, inserted in the above-mentioned book.
  • Many of the miracles of Abbé Paris were proved immediately by
  • witnesses before the officiality or bishop's court at Paris,
  • under the eye of cardinal Noailles, whose character for
  • integrity and capacity was never contested even by his enemies.
  • His successor in the archbishopric was an enemy to the
  • Jansenists, and for that reason promoted to the see by the
  • court. Yet 22 rectors or curés of Paris, with infinite
  • earnestness, press him to examine those miracles, which they
  • assert to be known to the whole world, and undisputably
  • certain: But he wisely forbore.
  • The Molinist party had tried to discredit these miracles in one
  • instance, that of Mademoiselle le Franc. But, besides that
  • their proceedings were in many respects the most irregular in
  • the world, particularly in citing only a few of the Jansenist
  • witnesses, whom they tampered with: Besides this, I say, they
  • soon found themselves overwhelmed by a cloud of new witnesses,
  • one hundred and twenty in number, most of them persons of
  • credit and substance in Paris, who gave oath for the miracle.
  • This was accompanied with a solemn and earnest appeal to the
  • parliament. But the parliament were forbidden by authority to
  • meddle in the affair. It was at last observed, that where men
  • are heated by zeal and enthusiasm, there is no degree of human
  • testimony so strong as may not be procured for the greatest
  • absurdity: And those who will be so silly as to examine the
  • affair by that medium, and seek particular flaws in the
  • testimony, are almost sure to be confounded. It must be a
  • miserable imposture, indeed, that does not prevail in
  • that contest.
  • All who have been in France about that time have heard of the
  • reputation of Mons. Heraut, the _lieutenant de Police_, whose
  • vigilance, penetration, activity, and extensive intelligence
  • have been much talked of. This magistrate, who by the nature of
  • his office is almost absolute, was vested with full powers, on
  • purpose to suppress or discredit these miracles; and he
  • frequently seized immediately, and examined the witnesses and
  • subjects of them: But never could reach any thing satisfactory
  • against them.
  • In the case of Mademoiselle Thibaut he sent the famous De Sylva
  • to examine her; whose evidence is very curious. The physician
  • declares, that it was impossible she could have been so ill as
  • was proved by witnesses; because it was impossible she could,
  • in so short a time, have recovered so perfectly as he found
  • her. He reasoned, like a man of sense, from natural causes; but
  • the opposite party told him, that the whole was a miracle, and
  • that his evidence was the very best proof of it.
  • The Molinists were in a sad dilemma. They durst not assert the
  • absolute insufficiency of human evidence, to prove a miracle.
  • They were obliged to say, that these miracles were wrought by
  • witchcraft and the devil. But they were told, that this was the
  • resource of the Jews of old.
  • No Jansenist was ever embarrassed to account for the cessation
  • of the miracles, when the church-yard was shut up by the king's
  • edict. It was the touch of the tomb, which produced these
  • extraordinary effects; and when no one could approach the tomb,
  • no effects could be expected. God, indeed, could have thrown
  • down the walls in a moment; but he is master of his own graces
  • and works, and it belongs not to us to account for them. He did
  • not throw down the walls of every city like those of Jericho,
  • on the sounding of the rams horns, nor break up the prison of
  • every apostle, like that of St. Paul.
  • No less a man, than the Due de Chatillon, a duke and peer of
  • France, of the highest rank and family, gives evidence of a
  • miraculous cure, performed upon a servant of his, who had lived
  • several years in his house with a visible and palpable
  • infirmity. I shall conclude with observing, that no clergy are
  • more celebrated for strictness of life and manners than the
  • secular clergy of France, particularly the rectors or curés of
  • Paris, who bear testimony to these impostures. The learning,
  • genius, and probity of the gentlemen, and the austerity of the
  • nuns of Port-Royal, have been much celebrated all over Europe.
  • Yet they all give evidence for a miracle, wrought on the niece
  • of the famous Pascal, whose sanctity of life, as well as
  • extraordinary capacity, is well known. The famous Racine gives
  • an account of this miracle in his famous history of Port-Royal,
  • and fortifies it with all the proofs, which a multitude of
  • nuns, priests, physicians, and men of the world, all of them of
  • undoubted credit, could bestow upon it. Several men of letters,
  • particularly the bishop of Tournay, thought this miracle so
  • certain, as to employ it in the refutation of atheists and
  • free-thinkers. The queen-regent of France, who was extremely
  • prejudiced against the Port-Royal, sent her own physician to
  • examine the miracle, who returned an absolute convert. In
  • short, the supernatural cure was so uncontestable, that it
  • saved, for a time, that famous monastery from the ruin with
  • which it was threatened by the Jesuits. Had it been a cheat, it
  • had certainly been detected by such sagacious and powerful
  • antagonists, and must have hastened the ruin of the contrivers.
  • Our divines, who can build up a formidable castle from such
  • despicable materials; what a prodigious fabric could they have
  • reared from these and many other circumstances, which I have
  • not mentioned! How often would the great names of Pascal,
  • Racine, Amaud, Nicole, have resounded in our ears? But if they
  • be wise, they had better adopt the miracle, as being more
  • worth, a thousand times, than all the rest of the collection.
  • Besides, it may serve very much to their purpose. For that
  • miracle was really performed by the touch of an authentic holy
  • prickle of the holy thorn, which composed the holy crown,
  • which, &c.
  • 97. Is the consequence just, because some human testimony has the utmost
  • force and authority in some cases, when it relates the battle of
  • Philippi or Pharsalia for instance; that therefore all kinds of
  • testimony must, in all cases, have equal force and authority? Suppose
  • that the Caesarean and Pompeian factions had, each of them, claimed the
  • victory in these battles, and that the historians of each party had
  • uniformly ascribed the advantage to their own side; how could mankind,
  • at this distance, have been able to determine between them? The
  • contrariety is equally strong between the miracles related by Herodotus
  • or Plutarch, and those delivered by Mariana, Bede, or any monkish
  • historian.
  • The wise lend a very academic faith to every report which favours the
  • passion of the reporter; whether it magnifies his country, his family,
  • or himself, or in any other way strikes in with his natural inclinations
  • and propensities. But what greater temptation than to appear a
  • missionary, a prophet, an ambassador from heaven? Who would not
  • encounter many dangers and difficulties, in order to attain so sublime a
  • character? Or if, by the help of vanity and a heated imagination, a man
  • has first made a convert of himself, and entered seriously into the
  • delusion; who ever scruples to make use of pious frauds, in support of
  • so holy and meritorious a cause?
  • The smallest spark may here kindle into the greatest flame; because the
  • materials are always prepared for it. The _avidum genus auricularum_[25],
  • the gazing populace, receive greedily, without examination, whatever
  • sooths superstition, and promotes wonder.
  • [25] Lucret.
  • How many stories of this nature have, in all ages, been detected and
  • exploded in their infancy? How many more have been celebrated for a
  • time, and have afterwards sunk into neglect and oblivion? Where such
  • reports, therefore, fly about, the solution of the phenomenon is
  • obvious; and we judge in conformity to regular experience and
  • observation, when we account for it by the known and natural principles
  • of credulity and delusion. And shall we, rather than have a recourse to
  • so natural a solution, allow of a miraculous violation of the most
  • established laws of nature?
  • I need not mention the difficulty of detecting a falsehood in any
  • private or even public history, at the place, where it is said to
  • happen; much more when the scene is removed to ever so small a distance.
  • Even a court of judicature, with all the authority, accuracy, and
  • judgement, which they can employ, find themselves often at a loss to
  • distinguish between truth and falsehood in the most recent actions. But
  • the matter never comes to any issue, if trusted to the common method of
  • altercations and debate and flying rumours; especially when men's
  • passions have taken part on either side.
  • In the infancy of new religions, the wise and learned commonly esteem
  • the matter too inconsiderable to deserve their attention or regard. And
  • when afterwards they would willingly detect the cheat, in order to
  • undeceive the deluded multitude, the season is now past, and the records
  • and witnesses, which might clear up the matter, have perished
  • beyond recovery.
  • No means of detection remain, but those which must be drawn from the
  • very testimony itself of the reporters: and these, though always
  • sufficient with the judicious and knowing, are commonly too fine to fall
  • under the comprehension of the vulgar.
  • 98. Upon the whole, then, it appears, that no testimony for any kind of
  • miracle has ever amounted to a probability, much less to a proof; and
  • that, even supposing it amounted to a proof, it would be opposed by
  • another proof; derived from the very nature of the fact, which it would
  • endeavour to establish. It is experience only, which gives authority to
  • human testimony; and it is the same experience, which assures us of the
  • laws of nature. When, therefore, these two kinds of experience are
  • contrary, we have nothing to do but substract the one from the other,
  • and embrace an opinion, either on one side or the other, with that
  • assurance which arises from the remainder. But according to the
  • principle here explained, this substraction, with regard to all popular
  • religions, amounts to an entire annihilation; and therefore we may
  • establish it as a maxim, that no human testimony can have such force as
  • to prove a miracle, and make it a just foundation for any such system
  • of religion.
  • 99. I beg the limitations here made may be remarked, when I say, that a
  • miracle can never be proved, so as to be the foundation of a system of
  • religion. For I own, that otherwise, there may possibly be miracles, or
  • violations of the usual course of nature, of such a kind as to admit of
  • proof from human testimony; though, perhaps, it will be impossible to
  • find any such in all the records of history. Thus, suppose, all authors,
  • in all languages, agree, that, from the first of January 1600, there was
  • a total darkness over the whole earth for eight days: suppose that the
  • tradition of this extraordinary event is still strong and lively among
  • the people: that all travellers, who return from foreign countries,
  • bring us accounts of the same tradition, without the least variation or
  • contradiction: it is evident, that our present philosophers, instead of
  • doubting the fact, ought to receive it as certain, and ought to search
  • for the causes whence it might be derived. The decay, corruption, and
  • dissolution of nature, is an event rendered probable by so many
  • analogies, that any phenomenon, which seems to have a tendency towards
  • that catastrophe, comes within the reach of human testimony, if that
  • testimony be very extensive and uniform.
  • But suppose, that all the historians who treat of England, should agree,
  • that, on the first of January 1600, Queen Elizabeth died; that both
  • before and after her death she was seen by her physicians and the whole
  • court, as is usual with persons of her rank; that her successor was
  • acknowledged and proclaimed by the parliament; and that, after being
  • interred a month, she again appeared, resumed the throne, and governed
  • England for three years: I must confess that I should be surprised at
  • the concurrence of so many odd circumstances, but should not have the
  • least inclination to believe so miraculous an event. I should not doubt
  • of her pretended death, and of those other public circumstances that
  • followed it: I should only assert it to have been pretended, and that it
  • neither was, nor possibly could be real. You would in vain object to me
  • the difficulty, and almost impossibility of deceiving the world in an
  • affair of such consequence; the wisdom and solid judgement of that
  • renowned queen; with the little or no advantage which she could reap
  • from so poor an artifice: All this might astonish me; but I would still
  • reply, that the knavery and folly of men are such common phenomena, that
  • I should rather believe the most extraordinary events to arise from
  • their concurrence, than admit of so signal a violation of the laws
  • of nature.
  • But should this miracle be ascribed to any new system of religion; men,
  • in all ages, have been so much imposed on by ridiculous stories of that
  • kind, that this very circumstance would be a full proof of a cheat, and
  • sufficient, with all men of sense, not only to make them reject the
  • fact, but even reject it without farther examination. Though the Being
  • to whom the miracle is ascribed, be, in this case, Almighty, it does
  • not, upon that account, become a whit more probable; since it is
  • impossible for us to know the attributes or actions of such a Being,
  • otherwise than from the experience which we have of his productions, in
  • the usual course of nature. This still reduces us to past observation,
  • and obliges us to compare the instances of the violation of truth in the
  • testimony of men, with those of the violation of the laws of nature by
  • miracles, in order to judge which of them is most likely and probable.
  • As the violations of truth are more common in the testimony concerning
  • religious miracles, than in that concerning any other matter of fact;
  • this must diminish very much the authority of the former testimony, and
  • make us form a general resolution, never to lend any attention to it,
  • with whatever specious pretence it may be covered.
  • Lord Bacon seems to have embraced the same principles of reasoning. 'We
  • ought,' says he, 'to make a collection or particular history of all
  • monsters and prodigious births or productions, and in a word of every
  • thing new, rare, and extraordinary in nature. But this must be done with
  • the most severe scrutiny, lest we depart from truth. Above all, every
  • relation must be considered as suspicious, which depends in any degree
  • upon religion, as the prodigies of Livy: And no less so, every thing
  • that is to be found in the writers of natural magic or alchimy, or such
  • authors, who seem, all of them, to have an unconquerable appetite for
  • falsehood and fable[26].'

  • 100. I am the better pleased with the method of reasoning here
  • delivered, as I think it may serve to confound those dangerous friends
  • or disguised enemies to the _Christian Religion_, who have undertaken to
  • defend it by the principles of human reason. Our most holy religion is
  • founded on _Faith_, not on reason; and it is a sure method of exposing
  • it to put it to such a trial as it is, by no means, fitted to endure. To
  • make this more evident, let us examine those miracles, related in
  • scripture; and not to lose ourselves in too wide a field, let us confine
  • ourselves to such as we find in the _Pentateuch_, which we shall
  • examine, according to the principles of these pretended Christians, not
  • as the word or testimony of God himself, but as the production of a mere
  • human writer and historian. Here then we are first to consider a book,
  • presented to us by a barbarous and ignorant people, written in an age
  • when they were still more barbarous, and in all probability long after
  • the facts which it relates, corroborated by no concurring testimony, and
  • resembling those fabulous accounts, which every nation gives of its
  • origin. Upon reading this book, we find it full of prodigies and
  • miracles. It gives an account of a state of the world and of human
  • nature entirely different from the present: Of our fall from that state:
  • Of the age of man, extended to near a thousand years: Of the destruction
  • of the world by a deluge: Of the arbitrary choice of one people, as the
  • favourites of heaven; and that people the countrymen of the author: Of
  • their deliverance from bondage by prodigies the most astonishing
  • imaginable: I desire any one to lay his hand upon his heart, and after a
  • serious consideration declare, whether he thinks that the falsehood of
  • such a book, supported by such a testimony, would be more extraordinary
  • and miraculous than all the miracles it relates; which is, however,
  • necessary to make it be received, according to the measures of
  • probability above established.
  • 101. What we have said of miracles may be applied, without any
  • variation, to prophecies; and indeed, all prophecies are real miracles,
  • and as such only, can be admitted as proofs of any revelation. If it did
  • not exceed the capacity of human nature to foretell future events, it
  • would be absurd to employ any prophecy as an argument for a divine
  • mission or authority from heaven. So that, upon the whole, we may
  • conclude, that the _Christian Religion_ not only was at first attended
  • with miracles, but even at this day cannot be believed by any reasonable
  • person without one. Mere reason is insufficient to convince us of its
  • veracity: And whoever is moved by _Faith_ to assent to it, is conscious
  • of a continued miracle in his own person, which subverts all the
  • principles of his understanding, and gives him a determination to
  • believe what is most contrary to custom and experience.
  • SECTION XI.
  • OF A PARTICULAR PROVIDENCE AND OF A FUTURE STATE.
  • 102. I was lately engaged in conversation with a friend who loves
  • sceptical paradoxes; where, though he advanced many principles, of which
  • I can by no means approve, yet as they seem to be curious, and to bear
  • some relation to the chain of reasoning carried on throughout this
  • enquiry, I shall here copy them from my memory as accurately as I can,
  • in order to submit them to the judgement of the reader.
  • Our conversation began with my admiring the singular good fortune of
  • philosophy, which, as it requires entire liberty above all other
  • privileges, and chiefly flourishes from the free opposition of
  • sentiments and argumentation, received its first birth in an age and
  • country of freedom and toleration, and was never cramped, even in its
  • most extravagant principles, by any creeds, concessions, or penal
  • statutes. For, except the banishment of Protagoras, and the death of
  • Socrates, which last event proceeded partly from other motives, there
  • are scarcely any instances to be met with, in ancient history, of this
  • bigotted jealousy, with which the present age is so much infested.
  • Epicurus lived at Athens to an advanced age, in peace and tranquillity:
  • Epicureans[27] were even admitted to receive the sacerdotal character,
  • and to officiate at the altar, in the most sacred rites of the
  • established religion: And the public encouragement[28] of pensions and
  • salaries was afforded equally, by the wisest of all the Roman
  • emperors[29], to the professors of every sect of philosophy. How
  • requisite such kind of treatment was to philosophy, in her early youth,
  • will easily be conceived, if we reflect, that, even at present, when she
  • may be supposed more hardy and robust, she bears with much difficulty
  • the inclemency of the seasons, and those harsh winds of calumny and
  • persecution, which blow upon her.

  • You admire, says my friend, as the singular good fortune of philosophy,
  • what seems to result from the natural course of things, and to be
  • unavoidable in every age and nation. This pertinacious bigotry, of which
  • you complain, as so fatal to philosophy, is really her offspring, who,
  • after allying with superstition, separates himself entirely from the
  • interest of his parent, and becomes her most inveterate enemy and
  • persecutor. Speculative dogmas of religion, the present occasions of
  • such furious dispute, could not possibly be conceived or admitted in the
  • early ages of the world; when mankind, being wholly illiterate, formed
  • an idea of religion more suitable to their weak apprehension, and
  • composed their sacred tenets of such tales chiefly as were the objects
  • of traditional belief, more than of argument or disputation. After the
  • first alarm, therefore, was over, which arose from the new paradoxes and
  • principles of the philosophers; these teachers seem ever after, during
  • the ages of antiquity, to have lived in great harmony with the
  • established superstition, and to have made a fair partition of mankind
  • between them; the former claiming all the learned and wise, the latter
  • possessing all the vulgar and illiterate.
  • 103. It seems then, say I, that you leave politics entirely out of the
  • question, and never suppose, that a wise magistrate can justly be
  • jealous of certain tenets of philosophy, such as those of Epicurus,
  • which, denying a divine existence, and consequently a providence and a
  • future state, seem to loosen, in a great measure, the ties of morality,
  • and may be supposed, for that reason, pernicious to the peace of
  • civil society.
  • I know, replied he, that in fact these persecutions never, in any age,
  • proceeded from calm reason, or from experience of the pernicious
  • consequences of philosophy; but arose entirely from passion and
  • prejudice. But what if I should advance farther, and assert, that if
  • Epicurus had been accused before the people, by any of the _sycophants_
  • or informers of those days, he could easily have defended his cause, and
  • proved his principles of philosophy to be as salutary as those of his
  • adversaries, who endeavoured, with such zeal, to expose him to the
  • public hatred and jealousy?
  • I wish, said I, you would try your eloquence upon so extraordinary a
  • topic, and make a speech for Epicurus, which might satisfy, not the mob
  • of Athens, if you will allow that ancient and polite city to have
  • contained any mob, but the more philosophical part of his audience, such
  • as might be supposed capable of comprehending his arguments.
  • The matter would not be difficult, upon such conditions, replied he: And
  • if you please, I shall suppose myself Epicurus for a moment, and make
  • you stand for the Athenian people, and shall deliver you such an
  • harangue as will fill all the urn with white beans, and leave not a
  • black one to gratify the malice of my adversaries.
  • Very well: Pray proceed upon these suppositions.
  • 104. I come hither, O ye Athenians, to justify in your assembly what I
  • maintained in my school, and I find myself impeached by furious
  • antagonists, instead of reasoning with calm and dispassionate enquirers.
  • Your deliberations, which of right should be directed to questions of
  • public good, and the interest of the commonwealth, are diverted to the
  • disquisitions of speculative philosophy; and these magnificent, but
  • perhaps fruitless enquiries, take place of your more familiar but more
  • useful occupations. But so far as in me lies, I will prevent this abuse.
  • We shall not here dispute concerning the origin and government of
  • worlds. We shall only enquire how far such questions concern the public
  • interest. And if I can persuade you, that they are entirely indifferent
  • to the peace of society and security of government, I hope that you will
  • presently send us back to our schools, there to examine, at leisure, the
  • question the most sublime, but at the same time, the most speculative of
  • all philosophy.
  • The religious philosophers, not satisfied with the tradition of your
  • forefathers, and doctrine of your priests (in which I willingly
  • acquiesce), indulge a rash curiosity, in trying how far they can
  • establish religion upon the principles of reason; and they thereby
  • excite, instead of satisfying, the doubts, which naturally arise from a
  • diligent and scrutinous enquiry. They paint, in the most magnificent
  • colours, the order, beauty, and wise arrangement of the universe; and
  • then ask, if such a glorious display of intelligence could proceed from
  • the fortuitous concourse of atoms, or if chance could produce what the
  • greatest genius can never sufficiently admire. I shall not examine the
  • justness of this argument. I shall allow it to be as solid as my
  • antagonists and accusers can desire. It is sufficient, if I can prove,
  • from this very reasoning, that the question is entirely speculative, and
  • that, when, in my philosophical disquisitions, I deny a providence and a
  • future state, I undermine not the foundations of society, but advance
  • principles, which they themselves, upon their own topics, if they argue
  • consistently, must allow to be solid and satisfactory.
  • 105. You then, who are my accusers, have acknowledged, that the chief or
  • sole argument for a divine existence (which I never questioned) is
  • derived from the order of nature; where there appear such marks of
  • intelligence and design, that you think it extravagant to assign for its
  • cause, either chance, or the blind and unguided force of matter. You
  • allow, that this is an argument drawn from effects to causes. From the
  • order of the work, you infer, that there must have been project and
  • forethought in the workman. If you cannot make out this point, you
  • allow, that your conclusion fails; and you pretend not to establish the
  • conclusion in a greater latitude than the phenomena of nature will
  • justify. These are your concessions. I desire you to mark the
  • consequences.
  • When we infer any particular cause from an effect, we must proportion
  • the one to the other, and can never be allowed to ascribe to the cause
  • any qualities, but what are exactly sufficient to produce the effect. A
  • body of ten ounces raised in any scale may serve as a proof, that the
  • counterbalancing weight exceeds ten ounces; but can never afford a
  • reason that it exceeds a hundred. If the cause, assigned for any effect,
  • be not sufficient to produce it, we must either reject that cause, or
  • add to it such qualities as will give it a just proportion to the
  • effect. But if we ascribe to it farther qualities, or affirm it capable
  • of producing other effects, we can only indulge the licence of
  • conjecture, and arbitrarily suppose the existence of qualities and
  • energies, without reason or authority.
  • The same rule holds, whether the cause assigned be brute unconscious
  • matter, or a rational intelligent being. If the cause be known only by
  • the effect, we never ought to ascribe to it any qualities, beyond what
  • are precisely requisite to produce the effect: Nor can we, by any rules
  • of just reasoning, return back from the cause, and infer other effects
  • from it, beyond those by which alone it is known to us. No one, merely
  • from the sight of one of Zeuxis's pictures, could know, that he was also
  • a statuary or architect, and was an artist no less skilful in stone and
  • marble than in colours. The talents and taste, displayed in the
  • particular work before us; these we may safely conclude the workman to
  • be possessed of. The cause must be proportioned to the effect; and if
  • we exactly and precisely proportion it, we shall never find in it any
  • qualities, that point farther, or afford an inference concerning any
  • other design or performance. Such qualities must be somewhat beyond what
  • is merely requisite for producing the effect, which we examine.
  • 106. Allowing, therefore, the gods to be the authors of the existence or
  • order of the universe; it follows, that they possess that precise degree
  • of power, intelligence, and benevolence, which appears in their
  • workmanship; but nothing farther can ever be proved, except we call in
  • the assistance of exaggeration and flattery to supply the defects of
  • argument and reasoning. So far as the traces of any attributes, at
  • present, appear, so far may we conclude these attributes to exist. The
  • supposition of farther attributes is mere hypothesis; much more the
  • supposition, that, in distant regions of space or periods of time, there
  • has been, or will be, a more magnificent display of these attributes,
  • and a scheme of administration more suitable to such imaginary virtues.
  • We can never be allowed to mount up from the universe, the effect, to
  • Jupiter, the cause; and then descend downwards, to infer any new effect
  • from that cause; as if the present effects alone were not entirely
  • worthy of the glorious attributes, which we ascribe to that deity. The
  • knowledge of the cause being derived solely from the effect, they must
  • be exactly adjusted to each other; and the one can never refer to
  • anything farther, or be the foundation of any new inference and
  • conclusion.
  • You find certain phenomena in nature. You seek a cause or author. You
  • imagine that you have found him. You afterwards become so enamoured of
  • this offspring of your brain, that you imagine it impossible, but he
  • must produce something greater and more perfect than the present scene
  • of things, which is so full of ill and disorder. You forget, that this
  • superlative intelligence and benevolence are entirely imaginary, or, at
  • least, without any foundation in reason; and that you have no ground to
  • ascribe to him any qualities, but what you see he has actually exerted
  • and displayed in his productions. Let your gods, therefore, O
  • philosophers, be suited to the present appearances of nature: and
  • presume not to alter these appearances by arbitrary suppositions, in
  • order to suit them to the attributes, which you so fondly ascribe to
  • your deities.
  • 107. When priests and poets, supported by your authority, O Athenians,
  • talk of a golden or silver age, which preceded the present state of vice
  • and misery, I hear them with attention and with reverence. But when
  • philosophers, who pretend to neglect authority, and to cultivate reason,
  • hold the same discourse, I pay them not, I own, the same obsequious
  • submission and pious deference. I ask; who carried them into the
  • celestial regions, who admitted them into the councils of the gods, who
  • opened to them the book of fate, that they thus rashly affirm, that
  • their deities have executed, or will execute, any purpose beyond what
  • has actually appeared? If they tell me, that they have mounted on the
  • steps or by the gradual ascent of reason, and by drawing inferences from
  • effects to causes, I still insist, that they have aided the ascent of
  • reason by the wings of imagination; otherwise they could not thus change
  • their manner of inference, and argue from causes to effects; presuming,
  • that a more perfect production than the present world would be more
  • suitable to such perfect beings as the gods, and forgetting that they
  • have no reason to ascribe to these celestial beings any perfection or
  • any attribute, but what can be found in the present world.
  • Hence all the fruitless industry to account for the ill appearances of
  • nature, and save the honour of the gods; while we must acknowledge the
  • reality of that evil and disorder, with which the world so much abounds.
  • The obstinate and intractable qualities of matter, we are told, or the
  • observance of general laws, or some such reason, is the sole cause,
  • which controlled the power and benevolence of Jupiter, and obliged him
  • to create mankind and every sensible creature so imperfect and so
  • unhappy. These attributes then, are, it seems, beforehand, taken for
  • granted, in their greatest latitude. And upon that supposition, I own
  • that such conjectures may, perhaps, be admitted as plausible solutions
  • of the ill phenomena. But still I ask; Why take these attributes for
  • granted, or why ascribe to the cause any qualities but what actually
  • appear in the effect? Why torture your brain to justify the course of
  • nature upon suppositions, which, for aught you know, may be entirely
  • imaginary, and of which there are to be found no traces in the course
  • of nature?
  • The religious hypothesis, therefore, must be considered only as a
  • particular method of accounting for the visible phenomena of the
  • universe: but no just reasoner will ever presume to infer from it any
  • single fact, and alter or add to the phenomena, in any single
  • particular. If you think, that the appearances of things prove such
  • causes, it is allowable for you to draw an inference concerning the
  • existence of these causes. In such complicated and sublime subjects,
  • every one should be indulged in the liberty of conjecture and argument.
  • But here you ought to rest. If you come backward, and arguing from your
  • inferred causes, conclude, that any other fact has existed, or will
  • exist, in the course of nature, which may serve as a fuller display of
  • particular attributes; I must admonish you, that you have departed from
  • the method of reasoning, attached to the present subject, and have
  • certainly added something to the attributes of the cause, beyond what
  • appears in the effect; otherwise you could never, with tolerable sense
  • or propriety, add anything to the effect, in order to render it more
  • worthy of the cause.
  • 108. Where, then, is the odiousness of that doctrine, which I teach in
  • my school, or rather, which I examine in my gardens? Or what do you find
  • in this whole question, wherein the security of good morals, or the
  • peace and order of society, is in the least concerned?
  • I deny a providence, you say, and supreme governor of the world, who
  • guides the course of events, and punishes the vicious with infamy and
  • disappointment, and rewards the virtuous with honour and success, in all
  • their undertakings. But surely, I deny not the course itself of events,
  • which lies open to every one's inquiry and examination. I acknowledge,
  • that, in the present order of things, virtue is attended with more peace
  • of mind than vice, and meets with a more favourable reception from the
  • world. I am sensible, that, according to the past experience of mankind,
  • friendship is the chief joy of human life, and moderation the only
  • source of tranquillity and happiness. I never balance between the
  • virtuous and the vicious course of life; but am sensible, that, to a
  • well-disposed mind, every advantage is on the side of the former. And
  • what can you say more, allowing all your suppositions and reasonings?
  • You tell me, indeed, that this disposition of things proceeds from
  • intelligence and design. But whatever it proceeds from, the disposition
  • itself, on which depends our happiness or misery, and consequently our
  • conduct and deportment in life is still the same. It is still open for
  • me, as well as you, to regulate my behaviour, by my experience of past
  • events. And if you affirm, that, while a divine providence is allowed,
  • and a supreme distributive justice in the universe, I ought to expect
  • some more particular reward of the good, and punishment of the bad,
  • beyond the ordinary course of events; I here find the same fallacy,
  • which I have before endeavoured to detect. You persist in imagining,
  • that, if we grant that divine existence, for which you so earnestly
  • contend, you may safely infer consequences from it, and add something
  • to the experienced order of nature, by arguing from the attributes which
  • you ascribe to your gods. You seem not to remember, that all your
  • reasonings on this subject can only be drawn from effects to causes; and
  • that every argument, deducted from causes to effects, must of necessity
  • be a gross sophism; since it is impossible for you to know anything of
  • the cause, but what you have antecedently, not inferred, but discovered
  • to the full, in the effect.
  • 109. But what must a philosopher think of those vain reasoners, who,
  • instead of regarding the present scene of things as the sole object of
  • their contemplation, so far reverse the whole course of nature, as to
  • render this life merely a passage to something farther; a porch, which
  • leads to a greater, and vastly different building; a prologue, which
  • serves only to introduce the piece, and give it more grace and
  • propriety? Whence, do you think, can such philosophers derive their idea
  • of the gods? From their own conceit and imagination surely. For if they
  • derived it from the present phenomena, it would never point to anything
  • farther, but must be exactly adjusted to them. That the divinity may
  • _possibly_ be endowed with attributes, which we have never seen exerted;
  • may be governed by principles of action, which we cannot discover to be
  • satisfied: all this will freely be allowed. But still this is mere
  • _possibility_ and hypothesis. We never can have reason to _infer_ any
  • attributes, or any principles of action in him, but so far as we know
  • them to have been exerted and satisfied.
  • _Are there any marks of a distributive justice in the world?_ If you
  • answer in the affirmative, I conclude, that, since justice here exerts
  • itself, it is satisfied. If you reply in the negative, I conclude, that
  • you have then no reason to ascribe justice, in our sense of it, to the
  • gods. If you hold a medium between affirmation and negation, by saying,
  • that the justice of the gods, at present, exerts itself in part, but not
  • in its full extent; I answer, that you have no reason to give it any
  • particular extent, but only so far as you see it, _at present_,
  • exert itself.
  • 110. Thus I bring the dispute, O Athenians, to a short issue with my
  • antagonists. The course of nature lies open to my contemplation as well
  • as to theirs. The experienced train of events is the great standard, by
  • which we all regulate our conduct. Nothing else can be appealed to in
  • the field, or in the senate. Nothing else ought ever to be heard of in
  • the school, or in the closet. In vain would our limited understanding
  • break through those boundaries, which are too narrow for our fond
  • imagination. While we argue from the course of nature, and infer a
  • particular intelligent cause, which first bestowed, and still preserves
  • order in the universe, we embrace a principle, which is both uncertain
  • and useless. It is uncertain; because the subject lies entirely beyond
  • the reach of human experience. It is useless; because our knowledge of
  • this cause being derived entirely from the course of nature, we can
  • never, according to the rules of just reasoning, return back from the
  • cause with any new inference, or making additions to the common and
  • experienced course of nature, establish any new principles of conduct
  • and behaviour.
  • 111. I observe (said I, finding he had finished his harangue) that you
  • neglect not the artifice of the demagogues of old; and as you were
  • pleased to make me stand for the people, you insinuate yourself into my
  • favour by embracing those principles, to which, you know, I have always
  • expressed a particular attachment. But allowing you to make experience
  • (as indeed I think you ought) the only standard of our judgement
  • concerning this, and all other questions of fact; I doubt not but, from
  • the very same experience, to which you appeal, it may be possible to
  • refute this reasoning, which you have put into the mouth of Epicurus.
  • If you saw, for instance, a half-finished building, surrounded with
  • heaps of brick and stone and mortar, and all the instruments of masonry;
  • could you not _infer_ from the effect, that it was a work of design and
  • contrivance? And could you not return again, from this inferred cause,
  • to infer new additions to the effect, and conclude, that the building
  • would soon be finished, and receive all the further improvements, which
  • art could bestow upon it? If you saw upon the sea-shore the print of one
  • human foot, you would conclude, that a man had passed that way, and that
  • he had also left the traces of the other foot, though effaced by the
  • rolling of the sands or inundation of the waters. Why then do you refuse
  • to admit the same method of reasoning with regard to the order of
  • nature? Consider the world and the present life only as an imperfect
  • building, from which you can infer a superior intelligence; and arguing
  • from that superior intelligence, which can leave nothing imperfect; why
  • may you not infer a more finished scheme or plan, which will receive its
  • completion in some distant point of space or time? Are not these methods
  • of reasoning exactly similar? And under what pretence can you embrace
  • the one, while you reject the other?
  • 112. The infinite difference of the subjects, replied he, is a
  • sufficient foundation for this difference in my conclusions. In works of
  • _human_ art and contrivance, it is allowable to advance from the effect
  • to the cause, and returning back from the cause, to form new inferences
  • concerning the effect, and examine the alterations, which it has
  • probably undergone, or may still undergo. But what is the foundation of
  • this method of reasoning? Plainly this; that man is a being, whom we
  • know by experience, whose motives and designs we are acquainted with,
  • and whose projects and inclinations have a certain connexion and
  • coherence, according to the laws which nature has established for the
  • government of such a creature. When, therefore, we find, that any work
  • has proceeded from the skill and industry of man; as we are otherwise
  • acquainted with the nature of the animal, we can draw a hundred
  • inferences concerning what may be expected from him; and these
  • inferences will all be founded in experience and observation. But did we
  • know man only from the single work or production which we examine, it
  • were impossible for us to argue in this manner; because our knowledge of
  • all the qualities, which we ascribe to him, being in that case derived
  • from the production, it is impossible they could point to anything
  • farther, or be the foundation of any new inference. The print of a foot
  • in the sand can only prove, when considered alone, that there was some
  • figure adapted to it, by which it was produced: but the print of a human
  • foot proves likewise, from our other experience, that there was probably
  • another foot, which also left its impression, though effaced by time or
  • other accidents. Here we mount from the effect to the cause; and
  • descending again from the cause, infer alterations in the effect; but
  • this is not a continuation of the same simple chain of reasoning. We
  • comprehend in this case a hundred other experiences and observations,
  • concerning the _usual_ figure and members of that species of animal,
  • without which this method of argument must be considered as fallacious
  • and sophistical.
  • 113. The case is not the same with our reasonings from the works of
  • nature. The Deity is known to us only by his productions, and is a
  • single being in the universe, not comprehended under any species or
  • genus, from whose experienced attributes or qualities, we can, by
  • analogy, infer any attribute or quality in him. As the universe shews
  • wisdom and goodness, we infer wisdom and goodness. As it shews a
  • particular degree of these perfections, we infer a particular degree of
  • them, precisely adapted to the effect which we examine. But farther
  • attributes or farther degrees of the same attributes, we can never be
  • authorised to infer or suppose, by any rules of just reasoning. Now,
  • without some such licence of supposition, it is impossible for us to
  • argue from the cause, or infer any alteration in the effect, beyond what
  • has immediately fallen under our observation. Greater good produced by
  • this Being must still prove a greater degree of goodness: a more
  • impartial distribution of rewards and punishments must proceed from a
  • greater regard to justice and equity. Every supposed addition to the
  • works of nature makes an addition to the attributes of the Author of
  • nature; and consequently, being entirely unsupported by any reason or
  • argument, can never be admitted but as mere conjecture and
  • hypothesis[30].
  • [30] In general, it may, I think, be established as a maxim,
  • that where any cause is known only by its particular effects,
  • it must be impossible to infer any new effects from that cause;
  • since the qualities, which are requisite to produce these new
  • effects along with the former, must either be different, or
  • superior, or of more extensive operation, than those which
  • simply produced the effect, whence alone the cause is supposed
  • to be known to us. We can never, therefore, have any reason to
  • suppose the existence of these qualities. To say, that the new
  • effects proceed only from a continuation of the same energy,
  • which is already known from the first effects, will not remove
  • the difficulty. For even granting this to be the case (which
  • can seldom be supposed), the very continuation and exertion of
  • a like energy (for it is impossible it can be absolutely the
  • same), I say, this exertion of a like energy, in a different
  • period of space and time, is a very arbitrary supposition, and
  • what there cannot possibly be any traces of in the effects,
  • from which all our knowledge of the cause is originally
  • derived. Let the _inferred_ cause be exactly proportioned (as
  • it should be) to the known effect; and it is impossible that
  • it can possess any qualities, from which new or different
  • effects can be _inferred_.
  • The great source of our mistake in this subject, and of the unbounded
  • licence of conjecture, which we indulge, is, that we tacitly consider
  • ourselves, as in the place of the Supreme Being, and conclude, that he
  • will, on every occasion, observe the same conduct, which we ourselves,
  • in his situation, would have embraced as reasonable and eligible. But,
  • besides that the ordinary course of nature may convince us, that almost
  • everything is regulated by principles and maxims very different from
  • ours; besides this, I say, it must evidently appear contrary to all
  • rules of analogy to reason, from the intentions and projects of men, to
  • those of a Being so different, and so much superior. In human nature,
  • there is a certain experienced coherence of designs and inclinations; so
  • that when, from any fact, we have discovered one intention of any man,
  • it may often be reasonable, from experience, to infer another, and draw
  • a long chain of conclusions concerning his past or future conduct. But
  • this method of reasoning can never have place with regard to a Being, so
  • remote and incomprehensible, who bears much less analogy to any other
  • being in the universe than the sun to a waxen taper, and who discovers
  • himself only by some faint traces or outlines, beyond which we have no
  • authority to ascribe to him any attribute or perfection. What we imagine
  • to be a superior perfection, may really be a defect. Or were it ever so
  • much a perfection, the ascribing of it to the Supreme Being, where it
  • appears not to have been really exerted, to the full, in his works,
  • savours more of flattery and panegyric, than of just reasoning and sound
  • philosophy. All the philosophy, therefore, in the world, and all the
  • religion, which is nothing but a species of philosophy, will never be
  • able to carry us beyond the usual course of experience, or give us
  • measures of conduct and behaviour different from those which are
  • furnished by reflections on common life. No new fact can ever be
  • inferred from the religious hypothesis; no event foreseen or foretold;
  • no reward or punishment expected or dreaded, beyond what is already
  • known by practice and observation. So that my apology for Epicurus will
  • still appear solid and satisfactory; nor have the political interests
  • of society any connexion with the philosophical disputes concerning
  • metaphysics and religion.
  • 114. There is still one circumstance, replied I, which you seem to have
  • overlooked. Though I should allow your premises, I must deny your
  • conclusion. You conclude, that religious doctrines and reasonings _can_
  • have no influence on life, because they _ought_ to have no influence;
  • never considering, that men reason not in the same manner you do, but
  • draw many consequences from the belief of a divine Existence, and
  • suppose that the Deity will inflict punishments on vice, and bestow
  • rewards on virtue, beyond what appear in the ordinary course of nature.
  • Whether this reasoning of theirs be just or not, is no matter. Its
  • influence on their life and conduct must still be the same. And, those,
  • who attempt to disabuse them of such prejudices, may, for aught I know,
  • be good reasoners, but I cannot allow them to be good citizens and
  • politicians; since they free men from one restraint upon their passions,
  • and make the infringement of the laws of society, in one respect, more
  • easy and secure.
  • After all, I may, perhaps, agree to your general conclusion in favour of
  • liberty, though upon different premises from those, on which you
  • endeavour to found it. I think, that the state ought to tolerate every
  • principle of philosophy; nor is there an instance, that any government
  • has suffered in its political interests by such indulgence. There is no
  • enthusiasm among philosophers; their doctrines are not very alluring to
  • the people; and no restraint can be put upon their reasonings, but what
  • must be of dangerous consequence to the sciences, and even to the state,
  • by paving the way for persecution and oppression in points, where the
  • generality of mankind are more deeply interested and concerned.
  • 115. But there occurs to me (continued I) with regard to your main
  • topic, a difficulty, which I shall just propose to you without insisting
  • on it; lest it lead into reasonings of too nice and delicate a nature.
  • In a word, I much doubt whether it be possible for a cause to be known
  • only by its effect (as you have all along supposed) or to be of so
  • singular and particular a nature as to have no parallel and no
  • similarity with any other cause or object, that has ever fallen under
  • our observation. It is only when two _species_ of objects are found to
  • be constantly conjoined, that we can infer the one from the other; and
  • were an effect presented, which was entirely singular, and could not be
  • comprehended under any known _species_, I do not see, that we could form
  • any conjecture or inference at all concerning its cause. If experience
  • and observation and analogy be, indeed, the only guides which we can
  • reasonably follow in inferences of this nature; both the effect and
  • cause must bear a similarity and resemblance to other effects and
  • causes, which we know, and which we have found, in many instances, to be
  • conjoined with each other. I leave it to your own reflection to pursue
  • the consequences of this principle. I shall just observe, that, as the
  • antagonists of Epicurus always suppose the universe, an effect quite
  • singular and unparalleled, to be the proof of a Deity, a cause no less
  • singular and unparalleled; your reasonings, upon that supposition, seem,
  • at least, to merit our attention. There is, I own, some difficulty, how
  • we can ever return from the cause to the effect, and, reasoning from our
  • ideas of the former, infer any alteration on the latter, or any
  • addition to it.
  • SECTION XII.
  • OF THE ACADEMICAL OR SCEPTICAL PHILOSOPHY.
  • PART I.
  • 116. There is not a greater number of philosophical reasonings,
  • displayed upon any subject, than those, which prove the existence of a
  • Deity, and refute the fallacies of _Atheists_; and yet the most
  • religious philosophers still dispute whether any man can be so blinded
  • as to be a speculative atheist. How shall we reconcile these
  • contradictions? The knights-errant, who wandered about to clear the
  • world of dragons and giants, never entertained the least doubt with
  • regard to the existence of these monsters.
  • The _Sceptic_ is another enemy of religion, who naturally provokes the
  • indignation of all divines and graver philosophers; though it is
  • certain, that no man ever met with any such absurd creature, or
  • conversed with a man, who had no opinion or principle concerning any
  • subject, either of action or speculation. This begets a very natural
  • question; What is meant by a sceptic? And how far it is possible to push
  • these philosophical principles of doubt and uncertainty?
  • There is a species of scepticism, _antecedent_ to all study and
  • philosophy, which is much inculcated by Des Cartes and others, as a
  • sovereign preservative against error and precipitate judgement. It
  • recommends an universal doubt, not only of all our former opinions and
  • principles, but also of our very faculties; of whose veracity, say they,
  • we must assure ourselves, by a chain of reasoning, deduced from some
  • original principle, which cannot possibly be fallacious or deceitful.
  • But neither is there any such original principle, which has a
  • prerogative above others, that are self-evident and convincing: or if
  • there were, could we advance a step beyond it, but by the use of those
  • very faculties, of which we are supposed to be already diffident. The
  • Cartesian doubt, therefore, were it ever possible to be attained by any
  • human creature (as it plainly is not) would be entirely incurable; and
  • no reasoning could ever bring us to a state of assurance and conviction
  • upon any subject.
  • It must, however, be confessed, that this species of scepticism, when
  • more moderate, may be understood in a very reasonable sense, and is a
  • necessary preparative to the study of philosophy, by preserving a proper
  • impartiality in our judgements, and weaning our mind from all those
  • prejudices, which we may have imbibed from education or rash opinion. To
  • begin with clear and self-evident principles, to advance by timorous and
  • sure steps, to review frequently our conclusions, and examine accurately
  • all their consequences; though by these means we shall make both a slow
  • and a short progress in our systems; are the only methods, by which we
  • can ever hope to reach truth, and attain a proper stability and
  • certainty in our determinations.
  • 117. There is another species of scepticism, _consequent_ to science and
  • enquiry, when men are supposed to have discovered, either the absolute
  • fallaciousness of their mental faculties, or their unfitness to reach
  • any fixed determination in all those curious subjects of speculation,
  • about which they are commonly employed. Even our very senses are brought
  • into dispute, by a certain species of philosophers; and the maxims of
  • common life are subjected to the same doubt as the most profound
  • principles or conclusions of metaphysics and theology. As these
  • paradoxical tenets (if they may be called tenets) are to be met with in
  • some philosophers, and the refutation of them in several, they naturally
  • excite our curiosity, and make us enquire into the arguments, on which
  • they may be founded.
  • I need not insist upon the more trite topics, employed by the sceptics
  • in all ages, against the evidence of _sense_; such as those which are
  • derived from the imperfection and fallaciousness of our organs, on
  • numberless occasions; the crooked appearance of an oar in water; the
  • various aspects of objects, according to their different distances; the
  • double images which arise from the pressing one eye; with many other
  • appearances of a like nature. These sceptical topics, indeed, are only
  • sufficient to prove, that the senses alone are not implicitly to be
  • depended on; but that we must correct their evidence by reason, and by
  • considerations, derived from the nature of the medium, the distance of
  • the object, and the disposition of the organ, in order to render them,
  • within their sphere, the proper _criteria_ of truth and falsehood. There
  • are other more profound arguments against the senses, which admit not of
  • so easy a solution.
  • 118. It seems evident, that men are carried, by a natural instinct or
  • prepossession, to repose faith in their senses; and that, without any
  • reasoning, or even almost before the use of reason, we always suppose an
  • external universe, which depends not on our perception, but would exist,
  • though we and every sensible creature were absent or annihilated. Even
  • the animal creation are governed by a like opinion, and preserve this
  • belief of external objects, in all their thoughts, designs, and actions.
  • It seems also evident, that, when men follow this blind and powerful
  • instinct of nature, they always suppose the very images, presented by
  • the senses, to be the external objects, and never entertain any
  • suspicion, that the one are nothing but representations of the other.
  • This very table, which we see white, and which we feel hard, is believed
  • to exist, independent of our perception, and to be something external
  • to our mind, which perceives it. Our presence bestows not being on it:
  • our absence does not annihilate it. It preserves its existence uniform
  • and entire, independent of the situation of intelligent beings, who
  • perceive or contemplate it.
  • But this universal and primary opinion of all men is soon destroyed by
  • the slightest philosophy, which teaches us, that nothing can ever be
  • present to the mind but an image or perception, and that the senses are
  • only the inlets, through which these images are conveyed, without being
  • able to produce any immediate intercourse between the mind and the
  • object. The table, which we see, seems to diminish, as we remove farther
  • from it: but the real table, which exists independent of us, suffers no
  • alteration: it was, therefore, nothing but its image, which was present
  • to the mind. These are the obvious dictates of reason; and no man, who
  • reflects, ever doubted, that the existences, which we consider, when we
  • say, _this house_ and _that tree_, are nothing but perceptions in the
  • mind, and fleeting copies or representations of other existences, which
  • remain uniform and independent.
  • 119. So far, then, are we necessitated by reasoning to contradict or
  • depart from the primary instincts of nature, and to embrace a new system
  • with regard to the evidence of our senses. But here philosophy finds
  • herself extremely embarrassed, when she would justify this new system,
  • and obviate the cavils and objections of the sceptics. She can no longer
  • plead the infallible and irresistible instinct of nature: for that led
  • us to a quite different system, which is acknowledged fallible and even
  • erroneous. And to justify this pretended philosophical system, by a
  • chain of clear and convincing argument, or even any appearance of
  • argument, exceeds the power of all human capacity.
  • By what argument can it be proved, that the perceptions of the mind
  • must be caused by external objects, entirely different from them, though
  • resembling them (if that be possible) and could not arise either from
  • the energy of the mind itself, or from the suggestion of some invisible
  • and unknown spirit, or from some other cause still more unknown to us?
  • It is acknowledged, that, in fact, many of these perceptions arise not
  • from anything external, as in dreams, madness, and other diseases. And
  • nothing can be more inexplicable than the manner, in which body should
  • so operate upon mind as ever to convey an image of itself to a
  • substance, supposed of so different, and even contrary a nature.
  • It is a question of fact, whether the perceptions of the senses be
  • produced by external objects, resembling them: how shall this question
  • be determined? By experience surely; as all other questions of a like
  • nature. But here experience is, and must be entirely silent. The mind
  • has never anything present to it but the perceptions, and cannot
  • possibly reach any experience of their connexion with objects. The
  • supposition of such a connexion is, therefore, without any foundation in
  • reasoning.
  • 120. To have recourse to the veracity of the supreme Being, in order to
  • prove the veracity of our senses, is surely making a very unexpected
  • circuit. If his veracity were at all concerned in this matter, our
  • senses would be entirely infallible; because it is not possible that he
  • can ever deceive. Not to mention, that, if the external world be once
  • called in question, we shall be at a loss to find arguments, by which we
  • may prove the existence of that Being or any of his attributes.
  • 121. This is a topic, therefore, in which the profounder and more
  • philosophical sceptics will always triumph, when they endeavour to
  • introduce an universal doubt into all subjects of human knowledge and
  • enquiry. Do you follow the instincts and propensities of nature, may
  • they say, in assenting to the veracity of sense? But these lead you to
  • believe that the very perception or sensible image is the external
  • object. Do you disclaim this principle, in order to embrace a more
  • rational opinion, that the perceptions are only representations of
  • something external? You here depart from your natural propensities and
  • more obvious sentiments; and yet are not able to satisfy your reason,
  • which can never find any convincing argument from experience to prove,
  • that the perceptions are connected with any external objects.
  • 122. There is another sceptical topic of a like nature, derived from the
  • most profound philosophy; which might merit our attention, were it
  • requisite to dive so deep, in order to discover arguments and
  • reasonings, which can so little serve to any serious purpose. It is
  • universally allowed by modern enquirers, that all the sensible qualities
  • of objects, such as hard, soft, hot, cold, white, black, &c. are merely
  • secondary, and exist not in the objects themselves, but are perceptions
  • of the mind, without any external archetype or model, which they
  • represent. If this be allowed, with regard to secondary qualities, it
  • must also follow, with regard to the supposed primary qualities of
  • extension and solidity; nor can the latter be any more entitled to that
  • denomination than the former. The idea of extension is entirely acquired
  • from the senses of sight and feeling; and if all the qualities,
  • perceived by the senses, be in the mind, not in the object, the same
  • conclusion must reach the idea of extension, which is wholly dependent
  • on the sensible ideas or the ideas of secondary qualities. Nothing can
  • save us from this conclusion, but the asserting, that the ideas of those
  • primary qualities are attained by _Abstraction_, an opinion, which, if
  • we examine it accurately, we shall find to be unintelligible, and even
  • absurd. An extension, that is neither tangible nor visible, cannot
  • possibly be conceived: and a tangible or visible extension, which is
  • neither hard nor soft, black nor white, is equally beyond the reach of
  • human conception. Let any man try to conceive a triangle in general,
  • which is neither _Isosceles_ nor _Scalenum_, nor has any particular
  • length or proportion of sides; and he will soon perceive the absurdity
  • of all the scholastic notions with regard to abstraction and
  • general ideas.[31]
  • [31] This argument is drawn from Dr. Berkeley; and indeed most
  • of the writings of that very ingenious author form the best
  • lessons of scepticism, which are to be found either among
  • the ancient or modern philosopher, Bayle not excepted. He
  • professes, however, in his title-page (and undoubtedly with
  • great truth) to have composed his book against the sceptics as
  • well as against the atheists and free-thinkers. But that all
  • his arguments, though otherwise intended, are, in reality,
  • merely sceptical, appears from this, _that they admit of no
  • answer and produce no conviction_. Their only effect is to
  • cause that momentary amazement and irresolution and confusion,
  • which is the result of scepticism.
  • 123. Thus the first philosophical objection to the evidence of sense or
  • to the opinion of external existence consists in this, that such an
  • opinion, if rested on natural instinct, is contrary to reason, and if
  • referred to reason, is contrary to natural instinct, and at the same
  • time carries no rational evidence with it, to convince an impartial
  • enquirer. The second objection goes farther, and represents this opinion
  • as contrary to reason: at least, if it be a principle of reason, that
  • all sensible qualities are in the mind, not in the object. Bereave
  • matter of all its intelligible qualities, both primary and secondary,
  • you in a manner annihilate it, and leave only a certain unknown,
  • inexplicable _something_, as the cause of our perceptions; a notion so
  • imperfect, that no sceptic will think it worth while to contend
  • against it.
  • PART II.
  • 124. It may seem a very extravagant attempt of the sceptics to destroy
  • _reason_ by argument and ratiocination; yet is this the grand scope of
  • all their enquiries and disputes. They endeavour to find objections,
  • both to our abstract reasonings, and to those which regard matter of
  • fact and existence.
  • The chief objection against all _abstract_ reasonings is derived from
  • the ideas of space and time; ideas, which, in common life and to a
  • careless view, are very clear and intelligible, but when they pass
  • through the scrutiny of the profound sciences (and they are the chief
  • object of these sciences) afford principles, which seem full of
  • absurdity and contradiction. No priestly _dogmas_, invented on purpose
  • to tame and subdue the rebellious reason of mankind, ever shocked common
  • sense more than the doctrine of the infinitive divisibility of
  • extension, with its consequences; as they are pompously displayed by all
  • geometricians and metaphysicians, with a kind of triumph and exultation.
  • A real quantity, infinitely less than any finite quantity, containing
  • quantities infinitely less than itself, and so on _in infinitum_; this
  • is an edifice so bold and prodigious, that it is too weighty for any
  • pretended demonstration to support, because it shocks the clearest and
  • most natural principles of human reason.[32] But what renders the matter
  • more extraordinary, is, that these seemingly absurd opinions are
  • supported by a chain of reasoning, the clearest and most natural; nor is
  • it possible for us to allow the premises without admitting the
  • consequences. Nothing can be more convincing and satisfactory than all
  • the conclusions concerning the properties of circles and triangles; and
  • yet, when these are once received, how can we deny, that the angle of
  • contact between a circle and its tangent is infinitely less than any
  • rectilineal angle, that as you may increase the diameter of the circle
  • _in infinitum_, this angle of contact becomes still less, even _in
  • infinitum_, and that the angle of contact between other curves and their
  • tangents may be infinitely less than those between any circle and its
  • tangent, and so on, _in infinitum_? The demonstration of these
  • principles seems as unexceptionable as that which proves the three
  • angles of a triangle to be equal to two right ones, though the latter
  • opinion be natural and easy, and the former big with contradiction and
  • absurdity. Reason here seems to be thrown into a kind of amazement and
  • suspence, which, without the suggestions of any sceptic, gives her a
  • diffidence of herself, and of the ground on which she treads. She sees a
  • full light, which illuminates certain places; but that light borders
  • upon the most profound darkness. And between these she is so dazzled and
  • confounded, that she scarcely can pronounce with certainty and assurance
  • concerning any one object.
  • [32] Whatever disputes there may be about mathematical points,
  • we must allow that there are physical points; that is, parts
  • of extension, which cannot be divided or lessened, either by
  • the eye or imagination. These images, then, which are present
  • to the fancy or senses, are absolutely indivisible, and
  • consequently must be allowed by mathematicians to be infinitely
  • less than any real part of extension; and yet nothing appears
  • more certain to reason, than that an infinite number of them
  • composes an infinite extension. How much more an infinite
  • number of those infinitely small parts of extension, which are
  • still supposed infinitely divisible.
  • 125. The absurdity of these bold determinations of the abstract sciences
  • seems to become, if possible, still more palpable with regard to time
  • than extension. An infinite number of real parts of time, passing in
  • succession, and exhausted one after another, appears so evident a
  • contradiction, that no man, one should think, whose judgement is not
  • corrupted, instead of being improved, by the sciences, would ever be
  • able to admit of it.
  • Yet still reason must remain restless, and unquiet, even with regard to
  • that scepticism, to which she is driven by these seeming absurdities and
  • contradictions. How any clear, distinct idea can contain circumstances,
  • contradictory to itself, or to any other clear, distinct idea, is
  • absolutely incomprehensible; and is, perhaps, as absurd as any
  • proposition, which can be formed. So that nothing can be more
  • sceptical, or more full of doubt and hesitation, than this scepticism
  • itself, which arises from some of the paradoxical conclusions of
  • geometry or the science of quantity.[33]
  • [33] It seems to me not impossible to avoid these absurdities
  • and contradictions, if it be admitted, that there is no such
  • thing as abstract or general ideas, properly speaking; but that
  • all general ideas are, in reality, particular ones, attached to
  • a general term, which recalls, upon occasion, other particular
  • ones, that resemble, in certain circumstances, the idea,
  • present to the mind. Thus when the term Horse is pronounced, we
  • immediately figure to ourselves the idea of a black or a white
  • animal, of a particular size or figure: But as that term is
  • also usually applied to animals of other colours, figures and
  • sizes, these ideas, though not actually present to the imagination,
  • are easily recalled; and our reasoning and conclusion proceed
  • in the same way, as if they were actually present. If this be
  • admitted (as seems reasonable) it follows that all the ideas of
  • quantity, upon which mathematicians reason, are nothing but
  • particular, and such as are suggested by the senses and
  • imagination, and consequently, cannot be infinitely divisible.
  • It is sufficient to have dropped this hint at present, without
  • prosecuting it any farther. It certainly concerns all lovers
  • of science not to expose themselves to the ridicule and
  • contempt of the ignorant by their conclusions; and this seems
  • the readiest solution of these difficulties.
  • 126. The sceptical objections to _moral_ evidence, or to the reasonings
  • concerning matter of fact, are either _popular_ or _philosophical_. The
  • popular objections are derived from the natural weakness of human
  • understanding; the contradictory opinions, which have been entertained
  • in different ages and nations; the variations of our judgement in
  • sickness and health, youth and old age, prosperity and adversity; the
  • perpetual contradiction of each particular man's opinions and
  • sentiments; with many other topics of that kind. It is needless to
  • insist farther on this head. These objections are but weak. For as, in
  • common life, we reason every moment concerning fact and existence, and
  • cannot possibly subsist, without continually employing this species of
  • argument, any popular objections, derived from thence, must be
  • insufficient to destroy that evidence. The great subverter of
  • _Pyrrhonism_ or the excessive principles of scepticism is action, and
  • employment, and the occupations of common life. These principles may
  • flourish and triumph in the schools; where it is, indeed, difficult, if
  • not impossible, to refute them. But as soon as they leave the shade, and
  • by the presence of the real objects, which actuate our passions and
  • sentiments, are put in opposition to the more powerful principles of our
  • nature, they vanish like smoke, and leave the most determined sceptic in
  • the same condition as other mortals.
  • 127. The sceptic, therefore, had better keep within his proper sphere,
  • and display those _philosophical_ objections, which arise from more
  • profound researches. Here he seems to have ample matter of triumph;
  • while he justly insists, that all our evidence for any matter of fact,
  • which lies beyond the testimony of sense or memory, is derived entirely
  • from the relation of cause and effect; that we have no other idea of
  • this relation than that of two objects, which have been frequently
  • _conjoined_ together; that we have no argument to convince us, that
  • objects, which have, in our experience, been frequently conjoined, will
  • likewise, in other instances, be conjoined in the same manner; and that
  • nothing leads us to this inference but custom or a certain instinct of
  • our nature; which it is indeed difficult to resist, but which, like
  • other instincts, may be fallacious and deceitful. While the sceptic
  • insists upon these topics, he shows his force, or rather, indeed, his
  • own and our weakness; and seems, for the time at least, to destroy all
  • assurance and conviction. These arguments might be displayed at greater
  • length, if any durable good or benefit to society could ever be expected
  • to result from them.
  • 128. For here is the chief and most confounding objection to _excessive_
  • scepticism, that no durable good can ever result from it; while it
  • remains in its full force and vigour. We need only ask such a sceptic,
  • _What his meaning is? And what he proposes by all these curious
  • researches?_ He is immediately at a loss, and knows not what to answer.
  • A Copernican or Ptolemaic, who supports each his different system of
  • astronomy, may hope to produce a conviction, which will remain constant
  • and durable, with his audience. A Stoic or Epicurean displays
  • principles, which may not be durable, but which have an effect on
  • conduct and behaviour. But a Pyrrhonian cannot expect, that his
  • philosophy will have any constant influence on the mind: or if it had,
  • that its influence would be beneficial to society. On the contrary, he
  • must acknowledge, if he will acknowledge anything, that all human life
  • must perish, were his principles universally and steadily to prevail.
  • All discourse, all action would immediately cease; and men remain in a
  • total lethargy, till the necessities of nature, unsatisfied, put an end
  • to their miserable existence. It is true; so fatal an event is very
  • little to be dreaded. Nature is always too strong for principle. And
  • though a Pyrrhonian may throw himself or others into a momentary
  • amazement and confusion by his profound reasonings; the first and most
  • trivial event in life will put to flight all his doubts and scruples, and
  • leave him the same, in every point of action and speculation, with the
  • philosophers of every other sect, or with those who never concerned
  • themselves in any philosophical researches. When he awakes from his
  • dream, he will be the first to join in the laugh against himself, and to
  • confess, that all his objections are mere amusement, and can have no
  • other tendency than to show the whimsical condition of mankind, who must
  • act and reason and believe; though they are not able, by their most
  • diligent enquiry, to satisfy themselves concerning the foundation of
  • these operations, or to remove the objections, which may be raised
  • against them.
  • PART III.
  • 129. There is, indeed, a more _mitigated_ scepticism or _academical_
  • philosophy, which may be both durable and useful, and which may, in
  • part, be the result of this Pyrrhonism, or _excessive_ scepticism, when
  • its undistinguished doubts are, in some measure, corrected by common
  • sense and reflection. The greater part of mankind are naturally apt to
  • be affirmative and dogmatical in their opinions; and while they see
  • objects only on one side, and have no idea of any counterpoising
  • argument, they throw themselves precipitately into the principles, to
  • which they are inclined; nor have they any indulgence for those who
  • entertain opposite sentiments. To hesitate or balance perplexes their
  • understanding, checks their passion, and suspends their action. They
  • are, therefore, impatient till they escape from a state, which to them
  • is so uneasy: and they think, that they could never remove themselves
  • far enough from it, by the violence of their affirmations and obstinacy
  • of their belief. But could such dogmatical reasoners become sensible of
  • the strange infirmities of human understanding, even in its most perfect
  • state, and when most accurate and cautious in its determinations; such a
  • reflection would naturally inspire them with more modesty and reserve,
  • and diminish their fond opinion of themselves, and their prejudice
  • against antagonists. The illiterate may reflect on the disposition of
  • the learned, who, amidst all the advantages of study and reflection, are
  • commonly still diffident in their determinations: and if any of the
  • learned be inclined, from their natural temper, to haughtiness and
  • obstinacy, a small tincture of Pyrrhonism might abate their pride, by
  • showing them, that the few advantages, which they may have attained over
  • their fellows, are but inconsiderable, if compared with the universal
  • perplexity and confusion, which is inherent in human nature. In
  • general, there is a degree of doubt, and caution, and modesty, which,
  • in all kinds of scrutiny and decision, ought for ever to accompany a
  • just reasoner.
  • 130. Another species of _mitigated_ scepticism which may be of advantage
  • to mankind, and which may be the natural result of the Pyrrhonian doubts
  • and scruples, is the limitation of our enquiries to such subjects as are
  • best adapted to the narrow capacity of human understanding. The
  • _imagination_ of man is naturally sublime, delighted with whatever is
  • remote and extraordinary, and running, without control, into the most
  • distant parts of space and time in order to avoid the objects, which
  • custom has rendered too familiar to it. A correct _Judgement_ observes a
  • contrary method, and avoiding all distant and high enquiries, confines
  • itself to common life, and to such subjects as fall under daily practice
  • and experience; leaving the more sublime topics to the embellishment of
  • poets and orators, or to the arts of priests and politicians. To bring
  • us to so salutary a determination, nothing can be more serviceable, than
  • to be once thoroughly convinced of the force of the Pyrrhonian doubt,
  • and of the impossibility, that anything, but the strong power of natural
  • instinct, could free us from it. Those who have a propensity to
  • philosophy, will still continue their researches; because they reflect,
  • that, besides the immediate pleasure, attending such an occupation,
  • philosophical decisions are nothing but the reflections of common life,
  • methodized and corrected. But they will never be tempted to go beyond
  • common life, so long as they consider the imperfection of those
  • faculties which they employ, their narrow reach, and their inaccurate
  • operations. While we cannot give a satisfactory reason, why we believe,
  • after a thousand experiments, that a stone will fall, or fire burn; can
  • we ever satisfy ourselves concerning any determination, which we may
  • form, with regard to the origin of worlds, and the situation of nature,
  • from, and to eternity?
  • This narrow limitation, indeed, of our enquiries, is, in every respect,
  • so reasonable, that it suffices to make the slightest examination into
  • the natural powers of the human mind and to compare them with their
  • objects, in order to recommend it to us. We shall then find what are the
  • proper subjects of science and enquiry.
  • 131. It seems to me, that the only objects of the abstract science or of
  • demonstration are quantity and number, and that all attempts to extend
  • this more perfect species of knowledge beyond these bounds are mere
  • sophistry and illusion. As the component parts of quantity and number
  • are entirely similar, their relations become intricate and involved; and
  • nothing can be more curious, as well as useful, than to trace, by a
  • variety of mediums, their equality or inequality, through their
  • different appearances. But as all other ideas are clearly distinct and
  • different from each other, we can never advance farther, by our utmost
  • scrutiny, than to observe this diversity, and, by an obvious reflection,
  • pronounce one thing not to be another. Or if there be any difficulty in
  • these decisions, it proceeds entirely from the undeterminate meaning of
  • words, which is corrected by juster definitions. That _the square of the
  • hypothenuse is equal to the squares of the other two sides_, cannot be
  • known, let the terms be ever so exactly defined, without a train of
  • reasoning and enquiry. But to convince us of this proposition, _that
  • where there is no property, there can be no injustice_, it is only
  • necessary to define the terms, and explain injustice to be a violation
  • of property. This proposition is, indeed, nothing but a more imperfect
  • definition. It is the same case with all those pretended syllogistical
  • reasonings, which may be found in every other branch of learning, except
  • the sciences of quantity and number; and these may safely, I think, be
  • pronounced the only proper objects of knowledge and demonstration.
  • 132. All other enquiries of men regard only matter of fact and
  • existence; and these are evidently incapable of demonstration. Whatever
  • _is_ may _not be_. No negation of a fact can involve a contradiction.
  • The non-existence of any being, without exception, is as clear and
  • distinct an idea as its existence. The proposition, which affirms it not
  • to be, however false, is no less conceivable and intelligible, than that
  • which affirms it to be. The case is different with the sciences,
  • properly so called. Every proposition, which is not true, is there
  • confused and unintelligible. That the cube root of 64 is equal to the
  • half of 10, is a false proposition, and can never be distinctly
  • conceived. But that Caesar, or the angel Gabriel, or any being never
  • existed, may be a false proposition, but still is perfectly conceivable,
  • and implies no contradiction.
  • The existence, therefore, of any being can only be proved by arguments
  • from its cause or its effect; and these arguments are founded entirely
  • on experience. If we reason _a priori_, anything may appear able to
  • produce anything. The falling of a pebble may, for aught we know,
  • extinguish the sun; or the wish of a man control the planets in their
  • orbits. It is only experience, which teaches us the nature and bounds of
  • cause and effect, and enables us to infer the existence of one object
  • from that of another[34]. Such is the foundation of moral reasoning,
  • which forms the greater part of human knowledge, and is the source of
  • all human action and behaviour.
  • [34] That impious maxim of the ancient philosophy, _Ex nihilo,
  • nihil fit_, by which the creation of matter was excluded,
  • ceases to be a maxim, according to this philosophy. Not only the
  • will of the supreme Being may create matter; but, for aught we
  • know _a priori_, the will of any other being might create it,
  • or any other cause, that the most whimsical imagination
  • can assign.
  • Moral reasonings are either concerning particular or general facts. All
  • deliberations in life regard the former; as also all disquisitions in
  • history, chronology, geography, and astronomy.
  • The sciences, which treat of general facts, are politics, natural
  • philosophy, physic, chemistry, &c. where the qualities, causes and
  • effects of a whole species of objects are enquired into.
  • Divinity or Theology, as it proves the existence of a Deity, and the
  • immortality of souls, is composed partly of reasonings concerning
  • particular, partly concerning general facts. It has a foundation in
  • _reason_, so far as it is supported by experience. But its best and most
  • solid foundation is _faith_ and divine revelation.
  • Morals and criticism are not so properly objects of the understanding as
  • of taste and sentiment. Beauty, whether moral or natural, is felt, more
  • properly than perceived. Or if we reason concerning it, and endeavour to
  • fix its standard, we regard a new fact, to wit, the general tastes of
  • mankind, or some such fact, which may be the object of reasoning
  • and enquiry.
  • When we run over libraries, persuaded of these principles, what havoc
  • must we make? If we take in our hand any volume; of divinity or school
  • metaphysics, for instance; let us ask, _Does it contain any abstract
  • reasoning concerning quantity or number?_ No. _Does it contain any
  • experimental reasoning concerning matter of fact and existence?_ No.
  • Commit it then to the flames: for it can contain nothing but sophistry
  • and illusion.

  • 23-33.
  • Reasonings _a priori_ give no knowledge of cause and effect,
  • 23 f.;

  • natural philosophy never pretends to assign ultimate causes, but only

  • yet we infer in the future a similar connexion between known
  • qualities of things and their secret powers, to that which
  • we assumed in the past. On what is this inference based? 29;

  • reasoning assumes the resemblance of the future to the past,
  • and so cannot prove it without being circular, 30, 32;
  • if reasoning were the basis of this belief, there would be no need

  • Experience enables us to ascribe a more than arbitrary connexion to
  • objects, 35;
  • we are determined to this by custom or habit which is the great guide
  • of human life, 36;
  • but our inference must be based on some fact present to the senses
  • or memory, 37;
  • the customary conjunction between such an object and some other
  • object produces an operation of the soul which is as
  • unavoidable as love, 38;
  • animals also infer one event from another by custom, 82-84;
  • and in man as in animals experimental reasoning depends on a species
  • of instinct or mechanical power that acts in us unknown to
  • ourselves, 85.
  • C. _Belief_, 39-45.
  • Belief differs from fiction or the loose reveries of the fancy by
  • some feeling annexed to it, 39;
  • belief cannot be defined, but may be described as a more lively,
  • forcible, firm, steady conception of an object than can be
  • attained by the imagination alone, 40;
  • it is produced by the principles of association, viz. resemblance,
  • 41;
  • contiguity, 42;
  • causation, 43;
  • by a kind of pre-established harmony between the course of nature
  • and our ideas, 44;
  • this operation of our minds necessary to our subsistence and so
  • entrusted by nature to instinct rather than to reasoning, 45.
  • _Probability_, 46-7.
  • Belief produced by a majority of chances by an inexplicable
  • contrivance of Nature, 46 (cf. 87-8);
  • probability of causes: the failure of a cause ascribed to a secret
  • counteracting cause, 47 (cf. 67);
  • it is universally allowed that chance when strictly examined is a
  • mere negative word, 74.
  • D. _Power_, 49-57.
  • Power, force, energy, necessary connexion must either be defined by
  • analysis or explained by production of the impression from
  • which they are copied, 49;
  • from the first appearance of an object we cannot foretell its effect:
  • we cannot see the power of a single body: we only see
  • sequence, 50.
  • Is the idea of power derived from an internal impression and is it an
  • idea of reflection? 51;
  • it is not derived, as Locke said, from reasoning about power of
  • production in nature, 50 n;
  • nor from consciousness of influence of will over bodily organs, 52;
  • nor from effort to overcome resistance, 52 n (cf. 60 n);
  • nor from influence of will over mind, 53;
  • many philosophers appeal to an invisible intelligent principle, to a
  • volition of the supreme being, and regard causes as only
  • occasions and our mental conceptions as revelations, 54-5;
  • thus diminishing the grandeur of God, 56;
  • this theory too bold and beyond verification by our faculties, and
  • is no explanation, 57;
  • vis inertiae, 57 n.
  • In single instances we only see sequence of loose events which are
  • conjoined and never connected, 58;
  • the idea of necessary connexion only arises from a number of similar
  • instances, and the only difference between such a number and
  • a single instance is that the former produces a habit of
  • expecting the usual attendant, 59, 61.
  • This customary transition is the impression from which we form the
  • idea of necessary connexion.
  • E. _Reasoning from effect to cause and conversely_, 105-115 (v.
  • _Providence_).
  • In arguing from effect to cause we must not infer more qualities in
  • the cause than are required to produce the effect, nor reason
  • backwards from an inferred cause to new effects, 105-8;
  • we can reason back from cause to new effects in the case of human
  • acts by analogy which rests on previous knowledge, 111-2;
  • when the effect is entirely singular and does not belong to any
  • species we cannot infer its cause at all, 115.

  • The sole argument for a divine existence is from the marks of design
  • in nature; must not infer greater power in the cause than is
  • necessary to produce the observed effects, nor argue from
  • such an inferred cause to any new effects which have not
  • been observed, 105;
  • so must not infer in God more power, wisdom, and benevolence than
  • appears in nature, 106;
  • so it is unnecessary to try and save the honour of the Gods by
  • assuming the intractability of matter or the observance of
  • general laws, 107;
  • to argue from effects to unknown causes, and then from these causes
  • to unknown effects, is a gross sophism, 108.
  • From imperfect exercise of justice in this world we cannot infer its
  • perfect exercise in a future world, 109;
  • we must regulate our conduct solely by the experienced train of
  • events, 110;
  • in case of human works of art we can infer the perfect from the
  • imperfect, but that is because we know man by experience and
  • also know other instances of his art, 111-112;
  • but in the case of God we only know him by his productions, and do
  • not know any class of beings to which he belongs, 113;

  • Scepticism

  • extravagant attempts of, to destroy reason by reasoning, 124.
  • No such absurd creature as a man who has no opinion about anything
  • at all, 116;
  • admits of no answer and produces no conviction, 122 n. (cf. 34, 126,
  • 128).
  • B. _As to the Senses_, 117-123.
  • The ordinary criticisms of our senses only show that they have to be
  • corrected by Reason, 117;
  • more profound arguments show that the vulgar belief in external
  • objects is baseless, and that the objects we see are nothing
  • but perceptions which are fleeting copies of other
  • existences, 118;
  • even this philosophy is hard to justify; it appeals neither to
  • natural instinct, nor to experience, for experience tells
  • nothing of objects which perceptions resemble, 119;
  • the appeal to the _veracity of God_ is useless, 120;
  • and scepticism is here triumphant, 121.
  • _The distinction between primary and secondary qualities_ is useless,
  • for the supposed primary qualities are only perceptions, 122;
  • and Berkeley's theory that ideas of primary qualities are obtained by
  • abstraction is impossible, 122, 122 n;
  • if matter is deprived of both primary and secondary qualities there
  • is nothing left except a mere something which is not worth
  • arguing about, 123.
  • C. _As to Reason_, 124-130.
  • Attempt to destroy Reason by reasoning extravagant, 124;
  • objection to _abstract reasoning_ because it asserts infinite
  • divisibility of extension which is shocking to common sense,
  • 124,
  • and infinite divisibility of time, 125;
  • yet the ideas attacked are so clear and distinct that scepticism
  • becomes sceptical about itself, 125.
  • Popular objections to _moral reasoning_ about matter of fact, based
  • on weakness of understanding, variation of judgement, and
  • disagreement among men, confuted by action, 126;
  • philosophical objections, that we only experience conjunction and
  • that inference is based on custom, 127;
  • excessive scepticism refuted by its uselessness and put to flight by
  • the most trivial event in life, 128.
  • Mitigated scepticism or academical philosophy useful as a corrective
  • and as producing caution and modesty, 129;
  • and as limiting understanding to proper objects, 130;
  • all reasoning which is not either abstract, about quantity and
  • number, or experimental, about matters of fact, is sophistry
  • and illusion, 132.

  • Project Gutenberg-tm is synonymous with the free distribution of
  • electronic works in formats readable by the widest variety of computers
  • including obsolete, old, middle-aged and new computers. It exists
  • because of the efforts of hundreds of volunteers and donations from
  • people in all walks of life.
  • Volunteers and financial support to provide volunteers with the
  • assistance they need are critical to reaching Project Gutenberg-tm's
  • goals and ensuring that the Project Gutenberg-tm collection will
  • remain freely available for generations to come. In 2001, the Project
  • Gutenberg Literary Archive Foundation was created to provide a secure
  • and permanent future for Project Gutenberg-tm and future generations.

  • Section 4. Information about Donations to the Project Gutenberg
  • Literary Archive Foundation
  • Project Gutenberg-tm depends upon and cannot survive without wide
  • spread public support and donations to carry out its mission of
  • increasing the number of public domain and licensed works that can be
  • freely distributed in machine readable form accessible by the widest
  • array of equipment including outdated equipment. Many small donations
  • ($1 to $5,000) are particularly important to maintaining tax exempt
  • status with the IRS.
  • The Foundation is committed to complying with the laws regulating
  • charities and charitable donations in all 50 states of the United
  • States. Compliance requirements are not uniform and it takes a
  • considerable effort, much paperwork and many fees to meet and keep up
  • with these requirements. We do not solicit donations in locations
  • where we have not received written confirmation of compliance. To
  • SEND DONATIONS or determine the status of compliance for any
  • particular state visit http://pglaf.org
  • While we cannot and do not solicit contributions from states where we
  • have not met the solicitation requirements, we know of no prohibition
  • against accepting unsolicited donations from donors in such states who
  • approach us with offers to donate.
  • International donations are gratefully accepted, but we cannot make
  • any statements concerning tax treatment of donations received from
  • outside the United States. U.S. laws alone swamp our small staff.
  • Please check the Project Gutenberg Web pages for current donation
  • methods and addresses. Donations are accepted in a number of other
  • ways including including checks, online payments and credit card
  • donations. To donate, please visit: http://pglaf.org/donate
  • Section 5. General Information About Project Gutenberg-tm electronic
  • works.
  • Professor Michael S. Hart is the originator of the Project Gutenberg-tm
  • concept of a library of electronic works that could be freely shared
  • with anyone. For thirty years, he produced and distributed Project
  • Gutenberg-tm eBooks with only a loose network of volunteer support.
  • Project Gutenberg-tm eBooks are often created from several printed
  • editions, all of which are confirmed as Public Domain in the U.S.
  • unless a copyright notice is included. Thus, we do not necessarily
