Gorgias , c.485-c.380 BC, Greek Sophist. From his native city, Leontini, Sicily, he was sent as an ambassador to Athens, where he settled to teach and practice rhetoric. Gorgias pursued the negative implications of the Eleatic school and asserted: (1) Nothing exists; (2) If anything does exist, it cannot be known; (3) If it can be known, the knowledge of it cannot be communicated. Objective truth being thus impossible, there remains only the art of the Sophists , persuasion. Such arguments undermined the foundations of polytheism and led to open challenges of current moral standards. His challenge to speculative thought stimulated a more sophisticated approach to the problems of philosophy. A dialogue of Plato's bears his name.

Gorgias

Gorgias (ca. 480-ca. 376 B.C.) was a Greek sophist and rhetorician. He believed that prose should rival poetry as a vehicle of persuasive and lofty expression and made important contributions to the development of epideictic, or ceremonial, oratory.

Gorgias was born in Leontini on the island of Sicily and is said to have lived more than 100 years. He went to Athens in 427 B.C. at the head of a delegation from his native city and caused a great stir with his new rhetorical style. His fame became immense throughout the Greek world, and according to Isocrates, his pupil, he was able to make a handsome fortune through the fees he charged. Noteworthy among the honors he received were invitations to deliver a funeral oration at Athens and to speak on Hellenic unity at Olympia. He was permitted to have a golden statue of himself erected at Delphi. Although he was popular, he was not without enemies, among whom was Aristophanes, the Athenian comic poet, who lampooned him and his extravagant rhetorical style in at least three comedies. Gorgias never married and left no direct descendants.

Writings and Ideas

Gorgias's writings include a single philosophical essay, listed by Sextus Empiricus as either On Being or On Nature, and Gorgias also wrote a Handbook of Rhetoric (now lost) and several speeches of which extensive fragments remain. The main points of the philosophical essay as preserved by Sextus are: nothing exists; if anything does exist, it is unknowable; if anything can be known, knowledge of it is incommunicable. In the tradition of Parmenides and Zeno of Elea, who developed certain types of rigorous logical arguments, Gorgias pursues an indirect kind of argumentation to arrive at an extreme conclusion.

More important than his contributions to philosophy are Gorgias's rhetorical works. His lost rhetorical treatise probably contained extensive examples of various types of arguments and rhetorical devices with little or no theoretical discussion (a fault of all of the handbooks before Aristotle). But if Gorgias published no elaborate theory, it is nevertheless evident from the extant Encomium of Helen that he had strong theoretical arguments for the power of the logos, and the importance and effect of his innovations could be readily seen in his successes as a speaker and teacher.

Gorgias's influence was immediate and widespread. His prose, which made lavish use of poetic diction, symmetrical clauses, various rhythms, and musical effects, revealed new possibilities to writers and speakers.
