Antisthenes

Antisthenes (c. 444-c. 371 bc), Greek philosopher, considered by some to be the founder of the school of philosophy known as cynicism. He was born in Athens and became a disciple of Socrates. Antisthenes taught in the gymnasium known as the Cynosarges outside Athens, and his followers were called cynics. Antisthenes, regarding happiness as attainable only through virtue, denounced art and literature, condemned luxury and comfort, and extolled hard work. His most famous pupil was the Greek cynic Diogenes of Sinope.
