Overview
Diogenes of Sinope (c. 412/403–c. 323 BCE) was the most famous Cynic, dramatizing austerity in the Athenian and Corinthian public eye. Anecdotes—lantern in daylight seeking an honest man, barrel dwelling, defying Alexander—define his legend more than treatises. He practiced shamelessness (anaideia) as critique of convention. Handbook dates are approximate across the fourth century BCE. Cynicism’s performance philosophy centers on him.
Main ideas
Virtue is life according to nature; social conventions that enslave desire deserve ridicule. Autarkeia (self-sufficiency) reduces needs to what a dog or sage can bear. Cosmopolitan identity—“citizen of the world”—relativizes polis snobbery. Shameless acts teach freedom from opinion (doxa). Philosophy is training (askesis), not bookish display. Frank speech (parrhesia) toward the powerful is a civic medicine.

Legacy
Diogenes became Western culture’s icon of philosophical insolence and voluntary poverty. Stoics softened Cynic askesis into systematized ethics. Modern countercultures continually restage his gestures.
