Epictetus was born a slave, in Phrygia, and spent his early life as the property of a freedman of Nero's court. He was lame — one account says his master broke his leg — and he was freed in his thirties, after which he taught until Domitian expelled the philosophers from Rome and he set up in Greece instead.

That biography is the reason he is the most useful Stoic to read. He is not describing an ideal life to people who already have options. He is telling someone with very little control over their circumstances where to put their effort.

The dichotomy, and the argument for it

The doctrine starts with a division, and the division is the whole of the practice.

> Some things are up to us and some are not up to us.

Up to us: judgment, desire, aversion, intention — the activity of the mind. Not up to us: the body, reputation, office, what other people do, what happens.

He is not the first Stoic to say this; it is implicit in Chrysippus. What he does is make it the organizing instruction rather than a piece of theory, and the argument he gives for it is worth having in full.

Anything not up to you can be taken. If you have built your sense of how life is going on things that can be taken, then your state is set by other people and by chance, and no amount of effort changes that. What is up to you cannot be taken by anybody. So the only durable investment is in the part you actually control.

Notice this is an argument about where effort pays, not a recommendation to stop caring. He is not saying your job does not matter. He is saying that your judgment about losing it is the part you can work on, and the losing is not.

The characteristic move that follows is reframing. You are not disturbed by events but by your judgments about events — so the work is done on the judgment, which is available, rather than the event, which is not.

How he taught

The Discourses are not written by him. Arrian, his student, took down what he said in class, which is why the voice is spoken and argumentative and often rude.

He interrogates, needles, mimics the excuses students bring him. He is unsparing about people who study philosophy as a subject rather than practicing it — there is a recurring contempt for the student who can explain Chrysippus and cannot control his temper. Philosophy, for Epictetus, is a training regime, and a man who knows the theory and is still ruled by his impulses has misunderstood what the theory was for.

The Enchiridion is Arrian's short distillation of the same material, and it is where most readers start.

The objection

The doctrine is criticized as quietism — a philosophy that teaches the powerless to accept powerlessness, invented by a slave and much appreciated by an emperor.

The charge lands more than the tradition likes. Epictetus is not interested in changing the arrangement that made him property, and the instruction to adjust your judgment rather than your circumstances is exactly what somebody benefiting from those circumstances would prefer you did.

The defense is that he is not addressing politics at all, and that a technique for not being destroyed by what you cannot change is compatible with changing what you can. That is a real answer. It is also, conveniently, an answer that never requires anything of anybody in charge — which is worth keeping in view while reading him.
