Gorgias

Gorgias ( ; ; – ) was an ancient Greek sophist, pre-Socratic philosopher, and rhetorician who was a native of Leontinoi in Sicily. Several doxographers report that he was a pupil of Empedocles, although he would only have been a few years younger. W. K. C. Guthrie writes that "Like other Sophists, he was an itinerant that practiced in various cities and giving public exhibitions of his skill at the great pan-Hellenic centers of Olympia and Delphi, and charged fees for his instruction and performances. A special feature of his displays was to ask miscellaneous questions from the audience and give impromptu replies." He has been called "Gorgias the Nihilist", although the degree to which this epithet adequately describes his philosophy is controversial.

Prominent among his claims to recognition is that he transplanted rhetoric from his native Sicily to Attica, and contributed to the diffusion of the Attic dialect as the language of literary prose. Provided by Wikipedia
