Among persons who, upon this subject, purged their eyes with rue and euphrasie, besides the Rev. Dr. Harsnet and many others (who wrote rather on special cases of Demonology than on the general question), Reginald Scot ought to be distinguished. Webster assures us that he was a “person of competent learning, pious, and of a good family.” He seems to have been a zealous Protestant, and much of his book, as well as that of Harsnet, is designed to throw upon the Papists in particular those tricks in which, by confederacy and imposture, the popular ideas concerning witchcraft, possession, and other supernatural fancies, were maintained and kept in exercise; but he also writes on the general question with some force and talent, considering that his subject is incapable of being reduced into a regular form, and is of a nature particularly seductive to an excursive talent. He appears to have studied legerdemain for the purpose of showing how much that is apparently unaccountable can nevertheless be performed without the intervention of supernatural assistance, even when it is impossible to persuade the vulgar that the devil has not been consulted on the occasion. Scot also had intercourse with some of the celebrated fortune-tellers, or Philomaths, of the time; one of whom he brings forward to declare the vanity of the science which he himself had once professed.
To defend the popular belief of witchcraft there arose a number of advocates, of whom Bodin and some others neither wanted knowledge nor powers of reasoning. They pressed the incredulous party with the charge that they denied the existence of a crime against which the law had denounced a capital punishment. As that law was understood to emanate from James himself, who was reigning monarch during the hottest part of the controversy, the English authors who defended the opposite side were obliged to entrench themselves under an evasion, to avoid maintaining an argument unpalatable to a degree to those in power, and which might perchance have proved unsafe to those who used it. With a certain degree of sophistry they answered that they did not doubt the possibility of witches, but only demurred to what is their nature, and how they came to be such—according to the scholastic jargon, that the question in respect to witches was not de existentia, but only de modo existendi.
By resorting to so subtle an argument those who impugned the popular belief were obliged, with some inconsistency, to grant that witchcraft had existed, and might exist, only insisting that it was a species of witchcraft consisting of they knew not what, but certainly of something different from that which legislators, judges, and juries had hitherto considered the statute as designed to repress.
