Hellenistic era

Socrates's impact was immense in philosophy after his death. With the exception of the Epicureans and the Pyrrhonists, almost all philosophical currents after Socrates traced their roots to him: Plato's Academy, Aristotle's Lyceum, the Cynics, and the Stoics. Interest in Socrates kept increasing until the third century AD. The various schools differed in response to fundamental questions such as the purpose of life or the nature of arete (virtue), since Socrates had not handed them an answer, and therefore, philosophical schools subsequently diverged greatly in their interpretation of his thought. He was considered to have shifted the focus of philosophy from a study of the natural world, as was the case for pre-Socratic philosophers, to a study of human affairs.
