Gorgias (ˈɡɔrdʒiəs; Γοργίας; 483–375 BC) was an ancient Greek sophist, pre-Socratic philosopher, and rhetorician who was a native of Leontinoi in Sicily. Along with Protagoras, he forms the first generation of Sophists. 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.
Gorgias was born 483 BC in Leontinoi, a Chalcidian colony in eastern Sicily that was allied with Athens. His father's name was Charmantides. He had a brother named Herodicus, who was a physician, and sometimes accompanied him during his travels. He also had a sister, whose name is not known, but whose grandson dedicated a golden statue to his great uncle at Delphi. It is not known whether Gorgias married or had children. Gorgias is said to have studied under the Sicilian philosopher Empedocles of Acragas ( 490 – 430 BC), but it is not known when, where, for how long, or in what capacity. He may have also studied under the rhetoricians Corax of Syracuse and Tisias, but very little is known about either of these men, nor is anything known about their relationship with Gorgias.
It is not known what kind of role Gorgias may have played in the politics in his native Leontinoi, but it is known that, in 427 BC, when he was around sixty years old, he was sent to Athens by his fellow-citizens as the head of an embassy to ask for Athenian protection against the aggression of the Syracusans.
