A former slave turned Stoic teacher who taught that we should care only about what is within our control.
See it on the Philosophy map →The idea
Idea: some things are up to us (our judgments, choices and desires) and some are not (body, property, reputation, other people). Distress comes from demanding control over the second group: 'It is not things that upset us, but our judgments about things.' Born a slave in Hierapolis (now Turkey), he was freed, taught in Rome, and after Domitian expelled philosophers around AD 93 ran a school at Nicopolis, Greece. Main objection: it can slide into passive acceptance of injustice.
Why it matters
His dichotomy of control directly shaped Marcus Aurelius, and the founders of cognitive behavioral therapy, Albert Ellis and Aaron Beck, cited him as a source.
Think of it like
Like an owner who controls upkeep and lease terms but not interest rates: run your part well and accept the market.
Legacy and sources
He wrote nothing; his student Arrian recorded his talks as the Discourses (four of eight books survive) and a short summary, the Handbook (Enchiridion).
Still debated
His exact dates are uncertain, and so is how faithfully Arrian's notes record his own words.
Connections (2)
▸Epictetus and the dichotomy of control taught Stoicism (founded by Zeno of Citium)Well documented
The connection
Epictetus made Stoicism a practical training for living. He boiled the system down to its ethical core, the dichotomy of control, and drilled students to examine each impression before accepting it. His school at Nicopolis became the best-known Stoic classroom of the Roman empire.
When and how
Rome, then Nicopolis in northwest Greece after about AD 93; his students included the historian Arrian.
How we know
Arrian's Discourses record his classroom sessions; Epictetus himself had studied under the Roman Stoic Musonius Rufus.
Debates and open questions
How much he passed on earlier Stoics like Chrysippus versus adding his own emphasis is unclear, because early Stoic works survive only in fragments.
▸Epictetus and the dichotomy of control inspired Marcus Aurelius, MeditationsWell documented
The connection
Marcus never met Epictetus but read his teachings as a young man and quotes him repeatedly. The Meditations' core method, sorting what is up to us from what is not and correcting our judgments, comes from Epictetus by way of Arrian's notes.
When and how
Rome, mid-2nd century AD; Marcus' tutor Junius Rusticus lent him a copy of Epictetus' discourses.
How we know
Meditations 1.7 thanks Rusticus for introducing him to Epictetus, and several passages quote Epictetus directly.
Debates and open questions
Whether Marcus read the same Arrian text we have, or a fuller version now lost, is unknown.
