Tindal, had carried to yet further lengths his service to the critical spirit. In his famous Free Inquiry into the miracles of post-apostolic Christianity (1749), again professing to strike at Rome, he had laid the foundations of a new structure of comparative criticism, and had given permanent grounds for rejecting the miracles of the sacred books. Middleton's book appeared a year after Hume's essay Of Miracles, and it made out no such philosophic case as Hume's against the concept of miracle; but it created at once, by its literary brilliance and its cogent argument, a sensation such as had thus far been made neither by Hume's philosophic argument nor by Francklin's anticipation of that. [861] Middleton had duly safeguarded himself by positing the certainty of the gospel miracles and of those wrought by the Apostles, on the old principle [862] that prodigies were divinely arranged so far forth as was necessary to establish Christianity, but no further. "The history of the gospel," he writes, "I hope may be true, though the history of the Church be fabulous." [863] But his argument against post-Apostolic miracles is so strictly naturalistic that no vigilant reader could fail to realize its fuller bearing upon all miracles whatsoever. With Hume and Francklin, he insisted that facts incredible in themselves could not be established by any amount or kind of testimony; and he suggested no measure of comparative credibility as between the two orders of miracle. With the deists in general, he argued that knowledge "either of the ways or will of the Creator" was to be had only through study of "that revelation which he made of himself from the beginning in the beautiful fabric of this visible world." [864] An antagonist accordingly wrote that his theses were: "First, that there were no miracles wrought in the primitive Church; Secondly, that all the primitive fathers were fools or knaves, and most of them both one and the other. And it is easy to observe, the whole tenor of your argument tends to prove, Thirdly, that no miracles were wrought by Christ or his apostles; and Fourthly, that these too were fools or knaves, or both." [865] A more temperate opponent pressed the same point in less explosive language. Citing Middleton's demand for an inductive method, this critic asks with much point: "What does he mean by 'deserting the path of Nature and experience,' but giving in to the belief of any miracles, and acknowledging the reality of events contrary to the known effects of the established Laws of Nature?"
