In this same work he presents, in condensed shape, the views of the advocates and of the opponents of spectral testimony, without striking the balance between them or avowedly taking sides with either, although it may fairly be observed that the weight he puts into the scale of the former is quite preponderating. From incidental expressions, too, it might be inferred that he was to be classed with the former, as he ascribes to them some "philosophical schemes," in explanation of the phenomena of witchcraft, that look like his notion of the "Plastic spirit of the world." Another incidental remark seems to point to Increase Mather, as to be classed with the latter, as follows: "Though against some of them that were tried, there came in so much other evidence of their diabolical compacts, that some of the most judicious, and yet vehement, opposers of the notions then in vogue, publicly declared, _Had they themselves been on the Bench, they could not have acquitted them_; nevertheless, divers were condemned, against whom the chief evidence was founded in the spectral exhibitions."
Increase Mather, in the Postscript to his _Cases of Conscience_, says: "I am glad that there is published to the World (by my Son) a _Breviate of the Tryals_ of some who were lately executed, whereby I hope the thinking part of Mankind will be satisfied, that there was more than that which is called _Spectre Evidence_ for the Conviction of the Persons condemned. I was not my self present at any of the Tryals, excepting one, _viz._ that of _George Burroughs_; had I been one of his Judges, I could not have acquitted him: For several Persons did upon Oath testifie, that they saw him do such things as no Man that has not a Devil to be his Familiar could perform."
It is observable that Increase Mather does not express or intimate, in this passage, any objection to the introduction of spectral evidence. When we come to consider Cotton Mather's _Breviate_ of the trial of George Burroughs, we shall see how slight and inadequate was what Increase Mather could have heard, _at the Trial_, to prove that Burroughs had exhibited strength which the Devil only could have supplied. The most trivial and impertinent matter was all that was needed, to be added to spectral testimony, to give it fatal effect. The value, by the way, of Increase Mather's averment, that "more than that which is called Spectre Evidence" was adduced against the persons convicted, is somewhat impaired by the admission of Cotton Mather, just before quoted, that "divers were condemned," against whom it was the "chief evidence."
