Crates of Thebes

Greek Cynic philosopher who was Zeno of Citium's teacher — and who famously gave away his considerable wealth to live as a homeless philosopher on the streets of Athens — representing the most radical form of philosophical indifference to social convention.

Demonstrates the Cynic foundation of Stoicism — Zeno learned from Crates that virtue is the only good and that social conventions are indifferent — and the radical life-philosophy that preceded Stoicism's more socially accommodating version of the same insight.
