The notification arrives like a slap. Someone has quote-tweeted you to their followers, or the group chat has gone quiet in the wrong way, or a colleague said the thing in the meeting — the pointed thing, aimed at you, in front of everyone. Your face goes hot. You draft the reply that will end them. You delete it. You draft it again. The rest of the day is gone, spent litigating a sentence in your own head.
Epictetus knew this feeling, and he had unusually hard credentials to speak on it. He was born a slave in the Roman Empire, lame in one leg, owned by another man before he ever owned himself. If anyone had grounds to be wounded by how he was treated, it was him. Instead he built an entire philosophy on a single hinge: some things are up to us, and some are not — and other people's opinions land squarely in the second pile.
In the Enchiridion, translated by Elizabeth Carter, he lays down the rule: "Men are disturbed not by the things which happen, but by the opinions about the things." The insult itself is just noise and air. What stings is the story you tell yourself about it. And he goes further, offering the one comeback worth keeping. If someone tells you a person has been speaking ill of you, he says, don't scramble to defend yourself — instead answer, in effect: he clearly didn't know the rest of my faults, or he'd have mentioned those too.
That's the whole trick, and it's better than any clapback. It refuses the fight without conceding the ground. It says: your assessment of me is your business, not my emergency.
So here is the landing. When someone comes for you, the impulse is to seize control of what they think — an impossible, exhausting project that hands them the steering wheel of your afternoon. Don't. Ask instead the only question that's actually yours to answer: Is any of it true? If it is, fix the thing quietly and thank them silently for the tip. If it isn't, let it sail past. Their opinion of you was never a possession of yours to defend. It was always theirs to hold.
A slave who owned his own mind was freer than the men who owned him. Guard the one thing they can't touch.
