# Θεαίτητος

By Plato.

"Θεαίτητος" by Plato is a dialogue written around 368-367 BCE. Socrates and the young mathematician Theaetetus explore three definitions of knowledge: knowledge as perception, knowledge as true judgment, and knowledge as true judgment with reason. Each definition proves unsatisfactory. The dialogue examines Protagoras's famous doctrine that "man is the measure of all things" and connects it to Heraclitus's theory of perpetual flux, questioning whether anything can be truly known when everything is constantly changing and relative.
