Who was Gorgias?

   Gorgias (485-c. 380 B.C.) was a Greek philosopher and rhetorician, was born in Leontini, Sicily, and spent the major part of his life in Athens. One of the leaders of the Sophists, Gorgias argued that being has no reality and that even if it had real existence it would be unknowable. Gorgias further maintained that even if any man was granted knowledge of existence, he could never impart it to any one else. The apparent contradictions and ambiguities of sense-perceptions led Gorgias to a subjectivism similar to that of Hume's. Plato immortalized him in his dialogue, Gorgias. In 427 B.C., Gorgias persuaded the people of Athens to form an alliance with the Leontines.
