Stoicism is a school of Hellenistic philosophy that flourished in Ancient Greece and Ancient Rome. The Stoics believed that the practice of virtue is enough to achieve eudaimonia: a well-lived life. The Stoics identified the path to achieving it with a life spent practicing the four virtues in everyday life: wisdom, courage, temperance or moderation, and justice, and living in accordance with nature. It was founded in the ancient Agora of Athens by Zeno of Citium around 300 BC.
