Ancient Greek philosophy · c. 404–323 BCE
Diogenes makes philosophy answer to a way of living, using simplicity and provocation to expose artificial needs and respectable pretence.

Diogenes of Sinope was a Greek Cynic philosopher remembered for making his manner of life part of his argument against convention. Much of the evidence about him is anecdotal, but the stories consistently present a radical test of status, wealth and respectability.
The question he enters
If a convention cannot survive one person refusing to perform it, how necessary was it?
The central move
The later anecdotes about Diogenes stage philosophical claims as actions: rejecting status, mocking definitions and reducing dependency on possessions. The point is not random rudeness. Cynic provocation asks whether social approval has mistaken its own rituals for human needs.
Key ideas

Provocation may reveal hypocrisy, but it can also centre the provocateur while leaving oppressive conditions unchanged.
