Stoicism

School of philosophy in Greco-Roman antiquity. Inspired by the teaching of Socrates and Diogenes of Sinope, Stoicism was founded at Athens by Zeno of Citium c. 300 BC and was influential throughout the Greco-Roman world until at least AD 200. It stressed duty and held that, through reason, mankind can come to regard the universe as governed by fate and, despite appearances, as fundamentally rational, and that, in regulating one's life, one can emulate the grandeur of the calm and order of the universe by learning to accept events with a stern and tranquil mind and to achieve a lofty moral worth. Its teachings have been transmitted to later generations largely through the surviving books of Cicero and the Roman Stoics Seneca, Epictetus, and Marcus Aurelius.
