Name: Socrates
Lived: c. 469–399 BC, Athens, Greece
Known for: Classical Greek philosopher and teacher of Plato
Famous for: Founder of the Socratic method; emphasized self-examination, ethics, and the pursuit of truth
Note: The phrase “I know that I know nothing” is attributed to Socrates, based on a passage in Plato’s Apology (c. 390 BC), where he says: “I do not know anything and do not think I do.” This reflects his belief that acknowledging ignorance is the first step toward true wisdom.
