Diogenes

Diogenes , c.412-323 BC, Greek Cynic philosopher; pupil of Antisthenes. He was born in Sinope and lived in Athens. He taught that the virtuous life is the simple life, and he dramatically discarded conventional comforts, living in a tub. He is said to have thrown away his last utensil, a cup, when he saw a peasant drink from his hands. When Alexander the Great asked what he might do for him, Diogenes said, "Only step out of my sunlight." His daylight quest with a lantern "for an honest man" was probably the most striking expression of his contempt for his generation.

Diogenes (active 4th century bc) Greek philosopher. Diogenes founded the Cynic school of philosophy. He believed that by reducing personal needs to a minimum, one can have mastery over one's soul.

Diogenes (c.400–c.325 bc), Greek philosopher. The most famous of the Cynic school, he lived ascetically in Athens (according to legend, he lived in a tub) and was accordingly named Kuōn (‘the dog’), from which the Cynics were then said to have derived their name. According to one story, he used to walk round Athens by day with a light, explaining that he was looking for an honest man. He emphasized self-sufficiency and the need for natural, uninhibited behaviour, regardless of social conventions.
