Gorgias (Greek: Γοργίας, ca.
485-c.380 BCE) "the Nihilist", Greek sophist, pre-socratic philosopher and rhetorician, was a native of Leontini 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. "Like other Sophists he was an itinerant, practicing 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 invite miscellaneous questions from the audience and give impromptu replies."
His chief claim to recognition resides in the fact 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 a Sicilian philosopher, orator, and rhetorician. He is considered by many scholars to be one of the founders of sophism, a movement traditionally associated with philosophy, that emphasizes the practical application of rhetoric toward civic and political life. The sophists were itinerant teachers who accepted fees in return for instruction in oratory and rhetoric, and many claimed they could teach anything and its opposite (thesis and antithesis). Another aspect of their method was the ability to make the weaker argument the stronger. The term sophist in classical Greek was a general appellation denoting a "wise man." They were important figures in Greece in the 4th and 5th centuries, and their social success was great. Plato was the first to use the term rhêtorikê, while the sophists termed their "art" logos . Nevertheless, Gorgias is commonly associated with the development of rhetoric in classical Greece. The democratic process in Athens supplied the need for instruction in both rhetoric and philosophy.
