"The defenders of the belief (Witchcraft), who were men of great and distinguished talent, maintained that there was no fact in all history more fully attested, and that to reject it would be to strike at the root of all historical evidence of the miraculous." (Lecky.)
The subject was examined in tens of thousands of cases, in almost every country in Europe, by tribunals which included the acutest lawyers and ecclesiastics of the ages, on the scene and at the time when the alleged acts had taken place, and with the assistance of innumerable sworn witnesses. The judges had no motive whatever to desire the condemnation of the accused, and as conviction would be followed by fearful death, they had the strongest motives to exercise their power with caution and deliberation. The whole force of public opinion was directed constantly and earnestly to the question for many centuries, and although there was some controversy concerning the details of witchcraft, the fact of its existence was long considered undoubted.
For many centuries the ablest men were not merely unwilling to repudiate the superstition, but they often pressed forward earnestly and with the utmost conviction to defend it. Indeed, during the period when witchcraft was most prevalent there were few writers of real eminence who did not, on some occasion, take especial pains to throw the weight of their authority into the scales.
St. Thomas Aquinas was probably the ablest writer of the thirteenth century, and he assures us that diseases and tempests are often the direct act of the Devil; and the Devil can transform men into any shape and transport them through the air.
Gerson, the chancellor of the University of Paris, and, as many think, the author of "The Imitation," is justly regarded as one of the master minds of his age; he too, wrote in defense of this belief. "These men," he wrote, "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."
Bodin was unquestionably the most original political philosopher who had arisen since Machiavelli, and he devoted all his learning and acuteness to crushing the rising scepticism on the subject of witches. The truth is that in those ages ability was no guarantee against error; for the single employment of the reason was to develop and expand premises that were furnished by the Church. And this statement is as valid today as it was three hundred years ago.
Bodin was esteemed, by many of his contemporaries, the ablest man who had then arisen in France, and the verdict has been but little qualified by later writers. Amid all the distractions of a dissipated and an intriguing court, and all the labors of a judicial position, he had amassed an amount of learning so vast and so various as to place him in the very first rank of the scholars of his nation. He has also the greater merit of being one of the chief founders of political philosophy and political history, and of having anticipated on these subjects many of the conclusions of our own day. In his judicial capacity he had presided at some trials of witchcraft. He had brought all the resources of his scholarship to bear upon the subject, and he had written a great part of his "Demonomanie des Sorciers" before the appearance of the last work of Wier.
John Wier was a physician of Cleves who had in 1563 published a work which he called, "De Præstigus Dæmonum." 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 reconcile his sense of their ubiquity with his persuasion that some of the phenomena that were deemed supernatural arose from disease.
"Wier," said Bodin, "had armed himself against God. His book was a tissue of 'horrible blasphemies.' For the word of God is very certain that he who suffers a man worthy of death to escape, draws the punishment upon himself, as the prophet said to King Ahab, that he would die for having pardoned a man worthy of death. For no one had ever heard of pardon accorded to sorcerers."
Such were the opinions which were promulgated towards the close of the sixteenth century by one of the most advanced intellects of one of the leading nations of Europe at that time; promulgated, too, with a tone of confidence and of triumph that shows how fully the writer could count upon the religious sympathies of his readers: the "Demonomanie des Sorciers" appeared in 1581.
