Socrates left no writings, took no fees, and founded no school with walls. What he did instead was walk the Athenian marketplace and talk — stopping generals, poets, and craftsmen to ask them what they meant by the words they used most confidently: justice, courage, piety, virtue. Again and again, the conversation revealed that the expert could not actually define the thing he claimed to know. This was the Socratic method at work: not teaching answers, but exposing the hollowness of unexamined certainty.
His trademark was a kind of strategic humility. Told by the Oracle at Delphi that no one was wiser than he, Socrates concluded the compliment could only mean this: others thought they knew things they did not, while he at least knew the extent of his own ignorance. That posture — questioning everything, assuming nothing — made him beloved by the young men who followed him and dangerous to those whose authority rested on never being questioned.
The trialDeath by hemlock.
In 399 BCE, Athens put Socrates on trial, charging him with impiety and corrupting the city's youth. Offered chances to propose exile or beg for mercy, he refused to betray his life's work, reportedly suggesting the city ought to reward rather than punish him. He was condemned to die by drinking hemlock. His composure in the face of death — recorded unforgettably by Plato — turned a local execution into the founding drama of Western philosophy.
Because he wrote nothing, almost everything we know comes filtered through others, chiefly his student Plato, whose dialogues feature Socrates as their central speaker. This creates the famous 'Socratic problem': separating the historical man from Plato's literary character is genuinely difficult. But the influence is beyond dispute. The method of learning by questioning, the conviction that virtue and knowledge are linked, and the ideal of the philosopher who follows the argument wherever it leads — all trace back to this one barefoot Athenian.
