Socrates

Socrates left no writings of his own, so everything known about his method comes from students who each shaped it to their own purposes. What survives consistently across Plato's dialogues and Xenophon's memoirs is a distinctive practice, later called the elenchus or Socratic method, in which he approached someone reputed to be wise, usually a politician, poet, or craftsman, and asked them to define a term central to their claimed expertise, such as courage, piety, or justice. He would then test the definition through further questions until it collapsed under its own contradictions, leaving both parties aware that the original confidence in the answer had been unearned. Socrates presented this as a service rather than an attack, comparing himself in the Theaetetus to a midwife who delivers other people's ideas rather than his own. He connected the practice to a report that the Delphic oracle had called him the wisest of the Greeks, which he took not as a claim to knowledge but as confirmation that true wisdom begins with recognizing one's own ignorance. The method produced no positive doctrine on its own, which is part of why ancient and modern readers disagree sharply about what, if anything, Socrates himself believed, as opposed to what Plato later placed in his mouth. What is not disputed is the method's afterlife, it shaped the dialogue form Plato built an entire school around and remains a recognizable teaching technique in ethics and law classrooms today.

In 399 BCE an Athenian jury of several hundred citizens convicted Socrates, then about seventy years old, on charges of impiety and of corrupting the young men of the city. Plato's Apology, written as a reconstruction of his defense speech, has him arguing that his questioning served the city rather than harmed it, and that he would rather die than abandon philosophy. The jury convicted him by a narrow margin and then, under Athenian procedure that let the defendant propose an alternative penalty, sentenced him to death after he treated the counterproposal with what ancient readers took as characteristic irony. Plato's Phaedo describes his final hours in an Athenian prison, drinking hemlock among his students while discussing the immortality of the soul, a scene that became one of the most retold death scenes in Western literature. Because virtually everything known about Socrates passes through students with their own philosophical agendas, chiefly Plato, Xenophon, and the comic playwright Aristophanes, scholars refer to the difficulty of recovering the historical man beneath their portraits as the Socratic problem. The trial itself is not in doubt, it is recorded independently across these sources and situated firmly in Athenian political history following the recent restoration of democracy, but how faithfully any single portrait captures what Socrates actually thought remains an open scholarly question.
