Heraclitus

c. 540 - c. 480 BCE · Greek (Ephesian) · Presocratic metaphysics

We step and we do not step into the same rivers, we are and we are not.

At the end of the sixth century BCE, an aristocrat from Ephesus renounced his hereditary title, withdrew from civic life, and deposited a book in the temple of Artemis — deliberately obscure, contemptuous of polymaths and sleepwalkers. Roughly 125 fragments survive in quotations by Plato, Aristotle, the Stoics, and later Christian writers.
