Diogenes
/dʌɪˈɒdʒɪniːz
/ (Circa 400-circa 325 bc), Greek philosopher. The most famous of the Cynics, he lived ascetically in Athens (according to legend, he lived in a tub) and was accordingly nicknamed Kuōn (‘the dog’), from which the Cynics derived their name. He emphasized self-sufficiency and the need for natural, uninhibited behaviour, regardless of social conventions.
