What happened

When the Oracle at Delphi told Socrates's friend Chaerephon that no one in Athens was wiser than Socrates, Socrates, genuinely puzzled since he felt he knew nothing of importance, set out to test the claim by questioning Athenians renowned for their wisdom. He concluded the oracle was right in an unexpected way: those with the strongest reputations for wisdom turned out to know the least, while he alone recognized his own ignorance. This habit of public, unrelenting cross-examination, conducted for free in the Athenian marketplace, made him popular with young aristocrats and deeply unpopular with the men he embarrassed. In 399 BCE he was charged with impiety and corrupting the youth of Athens, tried before a jury of 500 citizens, and executed by drinking hemlock after refusing both a professional legal defense and a clear chance to propose exile instead of death.

Why it matters

Socrates wrote nothing down himself, so his entire philosophical legacy survives only through students who each remembered him differently, most famously Plato, whose dialogues then shaped every philosophical school that followed, including ones with flatly contradictory values. His choice to accept execution rather than abandon his principles or flee the city became, on its own, one of the most argued-over acts in the history of philosophy.

How we know

Plato's Apology and Phaedo, written by a student who was present for at least part of the trial, describe Socrates's defense and final hours in detail, though historians still debate how much of Socrates in these texts is the real man versus Plato's own philosophical views placed in his teacher's mouth.
