"As the only Greek Pyrrhonian sceptic whose works survived, he came to have a dramatic role in the formation of modern thought. The historical accident of the rediscovery of his works at precisely the moment when the skeptical problem of the criterion had been raised gave the ideas of Sextus a sudden and greater prominence than they had ever before or were ever to have again. Thus, Sextus, a recently discovered oddity, metamorphosed into "le divin Sexte", who, by the end of the seventeenth century, was regarded as the father of modern philosophy. Moreover, in the late sixteenth and seventeenth centuries, the effect of his thoughts upon the problem of the criterion stimulated a quest for certainty that gave rise to the new rationalism of Ren Descartes and the "constructive skepticism" of Pierre Gassendi and Martin Mersenne." (Popkin, Skepticism, p. 18)." Sextus Empiricus's three known works are the Outlines of Pyrrhonism and two distinct works preserved under the same title, Against the Mathematicians, one of which is probably incomplete. This work appeared in several variants, the present one, printed in Geneva by the Chouët Brothers, one printed in Paris, and one printed in Orlans by the Chouët brothers, and one printed in Paris by Abraham Picard. All are uncommon.
