isocrates (436 avant j.-c. - 338 avant j.-c.)
Isocrates was an ancient Athenian orator, tutor, and writer.
He was born shortly before the outbreak of the Peloponnesian War (431-404 BC), and the turbulent life of the time directed the young Isocrates to write speeches for court appearances and politicians. His works were a success, and in 390 BC he founded a school whose students included prominent men from all over the Greek world. Isocrates' political beliefs caused a clash of interests with another demagogue, the famous anti-Macedonian Demosthenes (c. 384-322 BC). Moreover, Isocrates' beliefs, which were propagated through his school, also caused quarrels with other prominent figures in Greek philosophy, Plato (428/427-348/347 BC) and later Aristotle (384-322 BC).
Isocrates invested the wealth he had accumulated over time in the Athenian navy, earning him the title of trierarch. Having a reputation as a benefactor of Athens, he strove to be a moral educator as well. His most famous works, including Against the Sophists, Antidozis, Panegyric, To Philip, and Panatheneikus, provided this thinker with recognition from both ancient and modern audiences. The writings of Isocrates are an important historical source of information about the intellectual and political life of Athens in his time.
