Theaetetus

Theaetetus

by Plato


The Theaetetus is one of Plato's dialogues concerning the nature of knowledge, written circa 369 BC. In this dialogue, Socrates and Theaetetus discuss three definitions of knowledge: knowledge as nothing but perception, knowledge as true judgement, and, finally, knowledge as a true judgement with an account. Each of these definitions is shown to be unsatisfactory.
