THEAETETUS

What is knowledge—and how can we know that what we believe is true? In Theaetetus, Plato presents one of his most important philosophical dialogues, centered on a searching conversation between Socrates and the young mathematician Theaetetus. Together they examine whether knowledge can be identified with perception, true belief, or something more demanding. Through careful questioning and rigorous argument, Plato explores the relationship between sensation, judgment, truth, error, and human understanding. The dialogue does not settle for easy answers; instead, it challenges readers to think more deeply about what it means to know anything at all. Complete and unabridged, this edition presents Benjamin Jowett’s classic English translation of a foundational work in epistemology and ancient philosophy.
