Meaning

At first glance, saying the only real wisdom is knowing that you know nothing sounds like a paradox or even a form of false modesty. But the point is serious. A person who assumes they already understand the important things closes themselves off from genuine inquiry. Recognizing the limits of your own knowledge keeps curiosity alive and guards against the overconfidence that leads to poor reasoning and poor choices. Awareness of ignorance is the honest starting place for any real learning.

Context

This is a paraphrase drawn from Plato's Apology, the dialogue that records Socrates's defense speech at his trial. In that text, Socrates describes visiting people who had a reputation for wisdom, politicians, poets, and craftsmen, and finding that although they believed they were knowledgeable, their understanding was shallow or confined to a narrow domain. Socrates concluded that he had a small advantage over them: he did not think he knew things he did not know. The exact wording of the popular version is a condensed modern paraphrase rather than a direct translation.

About the author

Socrates was an Athenian philosopher of the fifth century BCE who fundamentally shaped the Western philosophical tradition. Because he wrote nothing, his thought survives mainly through the dialogues of Plato, his most celebrated student. Socrates was known above all for his method of questioning, now called the Socratic method, which used probing conversation to expose contradictions and unexamined assumptions. In 399 BCE he was convicted by an Athenian jury on charges of impiety and corrupting the youth, and he accepted his death sentence rather than abandon his philosophical practice.
