Asked what skill he possessed while being offered for sale, Diogenes is said to have answered that he could govern people. Then he pointed toward a prospective buyer who, in his judgment, needed a master.
The story reverses the expected balance of power. The man being sold behaves as though he is selecting someone to educate.
An anecdote preserved by an ancient biographer
The account appears in Book VI of Diogenes Laertius' Lives of the Eminent Philosophers. It concerns Diogenes of Sinope, the Cynic philosopher associated with rejecting luxury and social convention.
In the narrative, pirates capture him and he is sold to Xeniades of Corinth. Xeniades brings him into his household, where Diogenes takes responsibility for educating his sons.

Why the answer has lasted
A buyer at an auction expects to judge what another person can do for him. Diogenes instead presents judgment and leadership as the abilities on offer. Wealth can buy legal control in the story's setting, but it does not automatically confer wisdom.
That is the philosophical force of the anecdote. The relationship between outward status and inner independence becomes the subject of the scene.

A story about Diogenes, not a modern transcript
Diogenes Laertius wrote long after the philosopher's lifetime and collected traditions from different earlier authors. The tale should therefore be introduced as an ancient account, not as independently verified dialogue recorded at the auction.
Its clever reversal also does not make enslavement benign. The institution deprived people of freedom; the philosopher's confidence is the point of this particular literary portrait.
Stories about Diogenes often ask what a person truly needs and whose judgment deserves obedience. This one makes the question unusually sharp: if money and status do not create wisdom, who in the room is qualified to lead?
The answer offered by the anecdote has little to do with the auction price. It rests on the difference between possessing another person and knowing how to live.
