The dichotomy of control
Epictetus divides everything into what is up to us, our judgments and choices, and what is not, our body, reputation, and circumstances. Peace comes from investing only in the former and releasing the latter.
Discourses: Complete Books 1 - 4 - Adapted for the Contemporary Reader (Greek & Roman Stoic Philosophy)
4 ideas
It is not events but our opinions of them
People are disturbed not by things but by the views they take of them. Since judgment is within our power, distress can be revised at the source.
Freedom as inner independence
For Epictetus, a former slave, true freedom is not external liberty but not being enslaved to desires and fears. The free person wants only what is in their control.
Philosophy as daily practice, not theory
The Discourses treat philosophy as training, rehearsing responses to anger, loss, and temptation before they strike. Doctrine matters only insofar as it changes how you live and act.
