Diogenes of Sinope also known as Diogenes the Cynic was a Greek philosopher, born in Sinope about 412 BC and died in 323 BC at Corinth. Details of his life come in the form of anecdotes , especially from Diogenes Laërtius, in his book Lives and Opinions of Eminent Philosophers. Diogenes of Sinope was exiled from his native city and moved to Athens, where he is said to have become a disciple of Antisthenes, the former pupil of Socrates. Diogenes, a beggar who made his home in the streets of Athens, made a virtue of extreme poverty. He is said to have lived in a large tub, rather than a house, and to have walked through the streets carrying a lamp in the daytime, claiming to be looking for an honest man. He eventually settled in Corinth where he continued to pursue the Cynic ideal of self-sufficiency: a life which was natural and not dependent upon the luxuries of civilization. Believing that virtue was better revealed in action and not theory, his life was a relentless campaign to debunk the social values and institutions of what he saw as a corrupt society
