Socrates was born and died in Athens (c.470-399 BC). He was also one of the characters in Plato’s Atlantis Dialogues. Although Socrates left no writings, his ideas come to us through Plato and Xenophon. Socrates was Plato’s teacher and together with him and Aristotle, Plato’s pupil, they made up what is often referred to as the Heroic Trinity of Greek philosophy.
