Socrates
470 BCE – 399 BCE · Ancient Era
“True wisdom lies in recognizing one's own ignorance.”
Biography
Socrates shifted philosophy from cosmology to ethics and human life. Born the son of a stonemason and a midwife in Athens, he served with distinction as a soldier at Potidaea, Delium, and Amphipolis before devoting himself entirely to philosophical inquiry. He spent his days in the Athenian agora, engaging politicians, poets, and craftsmen in relentless questioning, testing their claims to knowledge and finding them wanting. He wrote nothing; his thought survives almost entirely through the dialogues of his student Plato and the memoirs of Xenophon. His physical appearance was famously homely, snub-nosed and stocky, yet his personal charisma was magnetic, attracting a devoted circle of young followers. In 399 BCE, he was tried on charges of impiety and corrupting the youth of Athens. Refusing to compromise his principles, he declined exile and accepted the death sentence, drinking hemlock in the company of his friends.
