The first author who stated fairly the connexion between the evidence of testimony and the evidence of experience, was Hume, in his Essay on Miracles; a work abounding in maxims of great use in the conduct of life.—Edinburgh Review, Sept. 1814, p. 328.
Several of the readers of this little work (first published in 1819) have derived much amusement from the mistakes of others respecting its nature and object. It has been by some represented as a serious attempt to inculcate universal scepticism; while others have considered it as a jeu d’esprit, etc. The author does not, however, design to entertain his readers with accounts of the mistakes which, have arisen respecting it; because many of them, he is convinced, would be received with incredulity; and he could not, without an indelicate exposure of individuals, verify his anecdotes.
But some sensible readers have complained of the difficulty of determining what they are to believe. Of the existence of Buonaparte, indeed, they remained fully convinced; nor, if it were left doubtful, would any important results ensue; but if they can give no satisfactory reason for their conviction, how can they know, it is asked, that they may not be mistaken as to other points of greater consequence, on which they are no less fully convinced, but on which all men are not agreed? The author has accordingly been solicited to endeavour to frame some canons which may furnish a standard for determining what evidence is to be received.
This he conceives to be impracticable, except to that extent to which it is accomplished by a sound system of Logic; including under that title, a portion—that which relates to the Laws of Evidence—of what is sometimes treated under the head of “Rhetoric.” But the full and complete accomplishment of such an object would confer on Man the unattainable attribute of infallibility.
But the difficulty complained of, he conceives to arise, in many instances, from men’s misstating the grounds of their own conviction. They are convinced, indeed, and perhaps with very sufficient reason; but they imagine this reason to be a different one from what it is. The evidence to which they have assented is applied to their minds in a different manner from that in which they believe that it is—and suppose that it ought to be—applied. And when challenged to defend and justify their own belief, they feel at a loss, because they are attempting to maintain a position which is not, in fact, that in which their force lies.
For a development of the nature, the consequences, and the remedies of this mistake, the reader is referred to Hinds on Inspiration, pp. 30-46. If such a development is to be found in any earlier works, the Author of the following pages at least has never chanced to meet with any attempt of the kind.
It has been objected, again, by some persons of no great logical accuracy of thought, that as there would not be any moral blame imputable to one who should seriously disbelieve, or doubt, the existence of Buonaparte, so neither is a rejection of the Scripture-histories to be considered as implying anything morally culpable.
The same objection, such as it is, would apply equally to many of the Parables of the New Testament. It might be said, for instance, that as a woman who should decline taking the trouble of searching for her lost “piece of silver,” or a merchant who should neglect making an advantageous purchase of a “goodly pearl,” would be guilty of no moral wrong, it must follow that there is nothing morally wrong in neglecting to reclaim a lost sinner, or in rejecting the Gospel, etc.
But any man of common sense readily perceives that the force of these parables consists in the circumstance that men do not usually show this carelessness about temporal goods; and, therefore, are guilty of gross and culpable inconsistency, if they are comparatively careless about what is far more important.
So, also, in the present case. If any man’s mind were so constituted as to reject the same evidence in all matters alike—if, for instance, he really doubted or disbelieved the existence of Buonaparte, and considered the Egyptian pyramids as fabulous, because, forsooth, he had no “experience” of the erection of such huge structures, and had experience of travellers telling huge lies—he would be regarded, perhaps, as very silly, or as insane, but not as morally culpable. But if (as is intimated in the concluding sentence of this work) a man is influenced in one case by objections which, in another case, he would deride, then he stands convicted of being unfairly biased by his prejudices.
It is only necessary to add, that as this work first appeared in the year 1819, many things are spoken of in the present tense, to which the past would now be applicable.

 It was observed by some reviewer, that Hume himself, had he been alive, would doubtless have highly enjoyed the joke! But even those who have the greatest delight in ridicule, do not relish jokes at their own expense. Hume may have inwardly laughed, while mystifying his readers with arguments which he himself perceived to be futile. But he did not mean the readers to perceive this. And it is not likely that he would have been amused at seeing his own fallacies exposed and held up to derision.
