 Richard Popkin has remarked that the great originality of La Vérité des sciences resides not so much in its arguments against the skeptics, as in the fact that this defense of “the truth of the sciences” concedes so much to the skeptical outlook. Most of the skeptical claims that are propounded either by the skeptic or by the Christian philosopher are not really refuted in the book. They are integrated in a novel view of what one should expect of scientific enquiry, its true aims and prospects (Popkin 1956, 2003).
