The formal structure of Gorgias' “On non-being or on nature” according to sextus empiricus' Adv. math. 7.65-87

The well-known evidence of Sextus Empiricus in Adv. Math. 7.65-87 is one of the two major evidence about Gorgias's treatise “On Not-Being or On Nature” along with “De Melisso Xenophane Gorgia”. The paper offers the analyses of the persuasive structure is this passage and discusses the arguments, which Sextus and, presumably, Gorgias use in this treatise. Also the paper compares formal persuasive structure of Gorgias' treatise as it presented in Adv. Math., on the one hand, and MXG, on the other.
