Diogenes

Diogenes (400-325 B.C.) was a Greek philosopher who became the most famous of the Cynics. In adherence to his philosophy, Diogenes lived in several poverty. By legend, he lived in a tub! His nickname was Greek for "the dog," from which the name "Cynic" derives. His teacher was Antisthenes.

Diogenes also believed in rejecting social conventions. For example, he supposedly carried a lantern by day, not by night, because he said he used it to look for an honest man.
