“The ‘Sadducismus Triumphatus,’ which is probably the ablest book ever published in defence of the superstition, opens with a striking picture of the rapid progress of the scepticism in England. Everywhere, a disbelief in witchcraft was becoming fashionable in the upper classes; but it was a disbelief that arose entirely from a strong sense of its antecedent improbability. All who were opposed to the orthodox faith united in discrediting witchcraft. They laughed at it, as palpably absurd, as involving the most grotesque and ludicrous conceptions, as so essentially incredible that it would be a waste of time to examine it. This spirit had arisen since the Restoration, although the laws were still in force, and although little or no direct reasoning had been brought to bear upon the subject. In order to combat it, Glanvil proceeded to examine the general question of the credibility of the miraculous. He saw that the reason why witchcraft was ridiculed was, because it was a phase of the miraculous and the work of the devil; that the scepticism was chiefly due to those who disbelieved in miracles and the devil; and that the instances of witchcraft or possession in the Bible were invariably placed on a level with those that were tried in the law courts of England. That the evidence of the belief was overwhelming, he firmly believed; and this, indeed, was scarcely disputed; but, until the sense of _à priori_ improbability was removed, no possible accumulation of facts would cause men to believe it. To that task he accordingly addressed himself. Anticipating the idea and almost the words of modern controversialists, he urged that there was such a thing as a credulity of unbelief; and that those who believed so strange a concurrence of delusions, as was necessary on the supposition of the unreality of witchcraft, were far more credulous than those who accepted the belief. He made his very scepticism his principal weapon; and, analyzing with much acuteness the _à priori_ objections, he showed that they rested upon an unwarrantable confidence in our knowledge of the laws of the spirit world; that they implied the existence of some strict analogy between the faculties of men and of spirits; and that, as such analogy most probably did not exist, no reasoning based on the supposition could dispense men from examining the evidence. He concluded with a large collection of cases, the evidence of which was, as he thought, incontestable.”
