Epictetus was born a slave and stayed one into his thirties, the property of a freedman in Nero’s court. The man’s name was Epaphroditus.
At some point the leg was broken; the students who wrote their teacher down said he had warned his master, mid-twist, that the bone would go, and when it went he said only that he had told him so.
He was lame for the rest of his life. What he taught, once he was freed and running a school in Nicopolis, began from that leg.
The first line of his handbook divides the world in two. Some things are up to us, he said, and some are not.
Our judgements, our aims, our own responses are up to us. Our bodies, our reputations, our property, the choices of other men are not.
The whole of the philosophy is learning which side of that line a thing sits on, and then stopping there.
A founder in Singapore builds a company on top of a model she does not own. Her product is good; the intelligence underneath it belongs to someone else.
A lab in San Francisco prices the thing she sells. Anthropic charges fifteen dollars for a million tokens of Claude’s output; OpenAI’s flagship charges thirty.
The price is a number on a page she refreshes and cannot argue with. One quarter it moves against her.
She had no vote, no warning she could act on, and a board meeting at nine with a gross margin that changed while she slept.
What is up to her is narrow, and it is real. A Chinese model, DeepSeek, will do frontier-adjacent work at twenty-eight cents for that same million tokens, close to a ninetieth of the American price.1
She can route between two providers. She can re-architect so no single vendor holds the whole product. She can raise her own prices, or absorb the hit, or leave.
None of that is comfortable and all of it is hers.
The pricing page is Epaphroditus. Her response is the will.
The pricing page is Epaphroditus. Her response is the will.
Epictetus had no dashboard. He had the same problem she does.
You can bind my leg, Epictetus told his students, but my will not even Zeus can overpower.
The founder’s error is almost always the same one, and it is seductive because it feels like work. She spends the night on the wrong side of the line: drafting the note to an account manager who cannot change the price, running the counterfactual where she picked the other platform in 2024, rehearsing the unfairness of a bill set by people who have never heard her name.
The hours pour into the thing she cannot move. The migration that is genuinely hers to do waits for morning, and it is smaller and later for having waited.
The line is a division of labour.
Draw it in the wrong place and you get both failures at once: rage at the market, which changes nothing, and neglect of the response, which was the only lever you were ever holding. Draw it where Epictetus drew it and the rage has nowhere to go, so it converts into the one motion that pays.
You can bind my leg, he told his students, but my will not even Zeus can overpower. He was describing a boundary, and telling them to stop spending themselves on the far side of it.
The leg stayed broken. He never pretended otherwise, and he never spent a sentence wishing it whole. He taught standing on it.
The price will move again next quarter, and the only question he leaves the founder is what she has already built by the time it does.

DeepSeek V4 Flash lists at $0.28 per million output tokens against $25 for Claude Opus 4.8 and $30 for OpenAI’s flagship. The gap is real. It is also a wager that the cheaper model stays good enough, which is a second thing not fully up to her, and Epictetus would have made her say so out loud. ↩
