It is a mistake to suppose that they had acted in any haphazard way. The conduct of both men had been based upon perfectly logical deductions from certain premises. King James's _Dæmonologie_ had been their catechism, the statute against the feeding of imps their book of rules. Both men started with one fundamental notion, that witchcraft is the keeping of imps. But this was a thing that could be detected by marks on the bodies.[81] Both were willing to admit that mistakes could be made and were often made in assuming that natural bodily marks were the Devil's marks. There were, however, special indications by which the difference between the two could be recognized.[82] And the two witchfinders, of course, possessed that "insight"[83] which was necessary to make the distinction. The theories upon which they worked we need not enter into. Suffice it to say that when once they had proved, as they thought, the keeping of imps, the next step was to watch those accused of it.[84] "For the watching," says Stearne,[85] "it is not to use violence or extremity to force them to confesse, but onely the keeping is, first to see whether any of their spirits, or familiars come to or neere them." It is clear that both Hopkins and Stearne recognized the fact that confessions wrung from women by torture are worthless and were by this explanation defending themselves against the charge of having used actual torture. There seems to be no adequate reason for doubting the sincerity of their explanation. Stearne tells us that the keeping the witches separate is "also to the end that Godly Divines might discourse with them." "For if any of their society come to them to discourse with them, they will never confesse."[86] Here, indeed, is a clue to many confessions. Several men arrayed against one solitary and weak woman could break her resolution and get from her very much what they pleased. As for starving the witches and keeping them from sleep, Stearne maintained that these things were done by them only at first. Hopkins bore the same testimony. "After they had beat their heads together in the Gaole, and after this use was not allowed of by the Judges and other Magistrates, it was never since used, which is a yeare and a halfe since."[87] In other words, the two men had given up the practice because the parliamentary commission had compelled them to do so.
