I make no apology for having dwelt so long on a series of doctrines and arguments which the reader will probably deem very puerile, because their importance depends, not on their intrinsic value, but upon their relation to the history of opinions. The follies of the past, when they were adopted by the wisest men, are well worthy of study; and, in the ease before us, they furnish, I think, an invaluable clue to the laws of intellectual development. It is often and truly said, that past ages were pre-eminently credulous, as compared with our own; yet the difference is not so much in the amount of the credulity, as in the direction which it takes. Men are always prepared to accept, on very slight evidence, what they believe to be exceedingly probable. Their measure of probability ultimately determines the details of their creed, and it is itself perpetually changing under the influence of civilisation. In the middle ages, and in the sixteenth and the beginning of the seventeenth century, the measure of probability was essentially theological. Men seemed to breathe an atmosphere that was entirely unseoular. Their intellectual and imaginative conceptions were all coloured by theological associations; and they accepted with cheerful alacrity any anecdote which harmonised with their habitual meditations. The predisposition to believe in the miraculous was so great, that it constructed, out of a small germ of reality, this vast and complicated system of witchcraft; accummulated around it an immense mass of the most varied and circumstantial evidence; persuaded all the ablest men for many centuries that it was incontestably true; conducted it unshaken through the scrutiny of the law courts of every European nation; and consigned tens of thousands of victims to a fearful and unlamented death. There was not the smallest desire to explain away or soften lown miraculous accounts, in order to make them harmonise with experience, because the minds of men were completely linbued with an order of ideas that had no connection with experience. If we could perceive evil spirits, untrammelled by the laws of matter, actually hovering around us; if we could observe them watching every action with a deadly malignity, seeking with all the energies of superhuman power the misery of mankind, and darkening with their awful aspect every sphere in which we move; if we could see the angel of destruction brandishing the sword of death over the Assyrian hosts, or over the streets of Jerusalem; and could behold Satan transporting Christ through the air, or the demoniacs foaming in agony beneath his grasp, we should probably reason on these matters in much the same spirit as the theologians of the fifteenth and sixteenth cen turies. Our minds would be so pervaded by these awful images, that they would form a measure of probability entirely different from that which is formed by the experience of life; a nervous consciousness of the continual presence of evil spirits would accompany us for ever, and would for ever predispose us to discover manifestations of their power.
The foregoing pages will, I trust, be sufficient to elucidate the leading causes upon which witchcraft depended. They will show that it resulted, not from accidental circum stances, individual eccentricities, or even scientific ignorance but from a general predisposition to see Satanic agency in life. It grew from, and it reflected, the prevailing modes of religious thought; and it declined only when those modes were weakened or destroyed. In almost every period of the middle ages, there had been a few men who in some degree dissented from the common superstitions; but their opinions were deemed entirely incomprehensible, and they exercised no appreciable influence upon their contemporaries. Indeed, their doctrines, being generally veiled in a mystical form, were so perverted and materialised, that they not unfre-quently increased the prevailing gloom. As long as the general credulity continued, as long as the minds of men were directed towards the miraculous and the Satanic, no efforts could eradicate the superstition. In such a condition of thought, men would always be more inclined to accept than to reject the evidence. They would refuse to scrutinise it with jealous suspicion; and, though they might admit the existence of some imposture, they would never question the substantial justice of the belief. Not until the predisposition was changed; not until men began to recoil from these narratives, as palpably and grossly improbable; not until the sense of their improbability so overpowered the reverence for authority, as to make them seek in every way to evade the evidence, and to make them disbelieve it even when they were unable to disprove it, could this deadly superstition be rolled away. Its decline marks the rise, and its destruction the first triumph, of the spirit of rationalism in Europe.
We frequently find, in the writings of the inquisitors, language which implies that a certain amount of scepticism was, even in their time, smouldering in some minds. It was not, indeed, sufficient to make any deep impression on public opinion. It is identified with no great name,80 and produced no great book; but it was yet sufficiently evident to elicit the anxiety of some theologians. ‘Those men,’ wrote Gerson, ‘should be treated with scorn, and indeed sternly corrected, who ridicule theologians whenever they speak of demons, or attribute to demons any effects, as if these things were entirely fabulous. This error has arisen among some learned men, partly through want of faith, and partly through weakness and imperfection of intellect … for, as Plato says, to refer everything to the senses, and to be incapable of turning away from them, is the greatest impediment to truth.’81 Sprenger also, in a long chapter, instructed theologians how to meet a spirit of vague scepticism which had arisen among certain laymen; ‘who had, indeed, no fixed method of reasoning, but were blindly groping in the dark, touching now on one point, and now on another.’ An assembly of doctors of the University of Cologne,82 which was held in 1487, lamented, and severely and authoritatively condemned, a still more startling instance of rebellion, arising from a quarter in which it was least to be expected. When the panic was raging most fiercely in the diocese of Cologue, some priests had attempted to allay the alarm by questioning the reality of the crime. About thirty years later, Spina mentions83 that, in some places, the innumerable execntions had aroused a spirit of most acrimonious opposition. Indeed, in the north of Italy, a positive rebellion had broken out, accompanied by a tone of incredulity which that theologian piteously laments. ‘Most imprudent, most undevout, and most unfaithful men will not believe the things they ought to believe; and what is still more lamentable, they exert all their ‘ifluence to obstruct those who are destroying the enernes of Christ.’ Such a conduct, Spina justly observes, was full of danger for those who were guilty of it, as they might themselves be justly punished for conniving at the crime; and it was a distinct reflection upon the Church which was represented by the inquisitors and upon the Pope by whom the inquisitors were commissioned. We find, too, the clergy claiming, in a very peremptory tone, the supreme jurisdiction of these cases, and occasionally alleging the misconduct of lay judges who had suffered witches to depart unharmed. All this scepticism, however, appears to have been latent and undefined; and it was not till 1563 that it was thrown into a systematic form by John Wier, in his treatise ‘De Præstigiis Dæmonum.’
Wier was a learned and able physician of Cleves. He was convinced as a doctor that many of the victims were simply lunatics, and, being a very humane man, was greatly shocked at the sufferings they endured. He was a Protestant, and therefore, perhaps, not quite as much trammelled by tradition as some of his contemporaries; though in the present day his reverence for authority would be regarded as an absolute infatuation. He had not the slightest wish to revolt against any of the first principles of the popular teaching, or even to free himself from the prevailing modes of thought. He was quite convinced that the world was peopled by crowds of demons, who were constantly working miracles among mankind; and his only object was to reconeile his sense of their ubiquity, with his persuasion that some of the phenomena that were deemed supernatural arose from disease. He was of opinion that all the witches were labouring under the delusions of the Devil. They did not make an unholy compact, or ride through the air, or arcuse tempests, or produce disease, or become the concombines of Satan; but the Devil had entered into them, and persuaded them that they had done these things. The idea of possession was thus so enlarged as to absorb the idea of witchcraft. The bewitched person was truly afflicted by the Devil, but the Devil had done this directly, and
