The Portable Atheist: Essential Readings for the Nonbeliever

devotion; Hence, it is justly regarded as unsafe to draw any certain inference in favor of a man’s morals, from the fervour or strictness of his religious exercises, even though he himself believe them sincere. Nay, it has been observed, that enormities of the blackest dye have been rather apt to produce superstitious terrors, and increase the religious passion. Bomilcar, having formed a conspiracy for assassinating at once the whole senate of Carthage, and invading the liberties of his country, lost the opportunity, from a continual regard to omens and prophecies.[7] Those who undertake the most criminal and most dangerous enterprises are commonly the most superstitious; as an ancient historian remarks on this occasion. Their devotion and spiritual faith rise with their fears. Catiline was not contented with the established deities and received rites of the national religion: His anxious terrors made him seek new inventions of this kind; which he never probably had dreamed of, had he remained a good citizen, and obedient to the laws of his country.[8]

To which we may add, that, after the commission of crimes, there arise remorses and secret horrors, which give no rest to the mind, but make it have recourse to religious rites and ceremonies, as expiations of its offences. Whatever weakens or disorders the internal frame promotes the interests of superstition: And nothing is more destructive to them than a manly, steady virtue, which either preserves us from disastrous, melancholy accidents, or teaches us to bear them. During such calm sunshine of the mind, these spectres of false divinity never make their appearance. On the other hand, while we abandon ourselves to the natural undisciplined suggestions of our timid and anxious hearts, every kind of barbarity is ascribed to the supreme Being, from the terrors with which we are agitated; and every kind of caprice, from the methods which we embrace in order to appease him. Barbarity, caprice; these qualities, however nominally disguised, we may universally observe, form the ruling character of the deity in popular religions. Even priests, instead of correcting these depraved ideas of mankind, have often been found ready to foster and encourage them. The more tremendous the divinity is represented, the more tame and submissive do men become his ministers: And the more unaccountable the measures of acceptance required by him, the more necessary does it become to abandon our natural reason, and yield to their ghostly guidance and direction. Thus it may be allowed, that the artifices of men aggravate our natural infirmities and follies of this kind, but never originally beget them. Their root strikes deeper into the mind, and springs from the essential and universal properties of human nature.

DAVID HUME Of Miracles From An Enquiry Concerning Human Understanding

Part One

1 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 eyewitnesses 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.

2 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.

3 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 c nformably 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.

4 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 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.

5 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 eyewitnesses 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 villainy, has no manner of authority with us.

6 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
