Lecture #16: Hume: "Essay on Miracles"

OF MIRACLES

by David Hume

I

            A wise man 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 judgment, 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.

            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 connection 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 favor of human testimony, whose connection with any event seems, in itself, as little necessary as any other. Were not the memory tenacious to a certain degree, had no men commonly an inclination to truth and a principle of probity, where they not sensible to shame when detected in a falsehood -- where 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 villainy 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 judgments 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 judgments, 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.

            This contrariety of evidence in the present case may be derived 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 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 endeavors to establish partakes of the extraordinary and the marvelous; 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 connection 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 endeavor to establish; from which contradiction there necessarily arises a counterpoise 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. The incredibility of a fact, it was allowed, might invalidate so great an authority . . . .

            But, in order to increase the probability against the testimony of witnesses, let us suppose that the fact which they affirm, instead of being only marvelous, 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.

            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 the falsehood would be more miraculous than the fact which it endeavors 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 is 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 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.

II

            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 show 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 any 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.

            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 reasoning is that the objects of which we have no experience resemble 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 toward 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 travelers 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 no 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 judgment to canvass his evidence. What judgment they have, the 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. This 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 hearer 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 marvelous, 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 neighborhood 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?

            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, judgments, 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 marvelous, 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 enow of that frailty. You have yourself heard many such marvelous 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 related . . . .

            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 subtle and refined, but it is not in reality different from the reasoning of a judge who supposes that the credit of two witnesses maintaining a crime against anyone is destroyed by the testimony of two others who affirm him to have been two hundred leagues distant at the same insstant when the crime is said to have been committed.

            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, 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 anyone 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 contemporary writer noted for candor 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 judgment 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, Ultrumque, 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.

            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 everybody 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 contemporary 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 Abbe 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 everywhere 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 everywhere; nor were the Jesuits, though a learned body, supported by the civil magistrate, and determined enemies to those opinions in whose favor the miracles were said to have been wrought, ever able distinctly to refute or detect them. 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 . . . .

            The wise lend a very academic faith to every report which favors 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, the gazing populace, receive greedily, without examination, whatever sooths superstition and promotes wonder.

            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 afterward 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 judgment 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 an issue, if trusted to the common method of altercation and debate and flying rumors, 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.

            Upon the whole, then, it appears that no testimony for any kind of miracle has ever amounted too 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 endeavor 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 subtract 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 subtraction, 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.

            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 travelers 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 probably by so many analogies that any phenomenon which seems to have a tendency toward 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 occurrence 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 possible 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 judgment of that renowned queen, with the little or no advantage that 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 reject it without further 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 observations, 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 pretense it may be covered …

            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 those 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 the 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 by near a thousand years: Of the destruction of the world by a deluge: Of the arbitrary choice of one people as the favorites of heaven, and that people of the countrymen of the author: Of their deliverance from bondage by prodigies the most astonishing imaginable. I desire anyone 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.

            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 at first was 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.
