Isocrates

436–338 BCE

Isocrates of Athens, a pupil of Gorgias and a companion of Socrates in his youth, founded the most famous school of rhetoric in Greece and taught there for fifty years. Too weak of voice to speak in the assembly, he published his counsel as written orations — the Panegyricus, On the Peace, the Areopagiticus, the Antidosis, the address To Philip — urging the Greeks to concord among themselves and Athens to moderation, and setting his education in speech and judgement, which he too called philosophy, against Plato's.
