Stoicism

Stoicism is a Hellenistic philosophy, founded in Athens by Zeno of Citium around 300 BCE, whose central claim is that virtue, a well-governed character, is the only real good, and that things like health, wealth, and reputation are worth preferring but not worth staking a life on. Its most portable practice comes from Epictetus: sort what is yours from what is not, because judgment, intention, and response belong to a person while events, outcomes, and other people do not. A life then goes well or badly according to how the first set is exercised rather than how the second falls out, which makes this a discipline of response rather than a promise of ease. Marcus Aurelius, Epictetus, and Seneca are the surviving voices most readers meet first, and Meditations is the usual door in. Worth knowing before opening it: that book was a private notebook, one Roman emperor arguing with himself in the middle of a hard job, not a systematic statement of the school, so it reads as practice rather than doctrine. It shows up on this site as a stance instead of a creed, because building things and staying steady both run into the same wall: the line between what can be changed and what can only be answered well.
