Diogenes of Sinope - Wikipedia, the free encyclopedia

Diogenes of Sinope - Wikipedia, the free encyclopedia: "Diogenes is credited with the first known use of the word 'cosmopolitan'. When he was asked where he came from, he replied, 'I am a citizen of the world (cosmopolites)'. This was a radical claim in a world where a man's identity was intimately tied to his citizenship in a particular city state. An exile and an outcast, a man with no social identity, Diogenes made a mark on his contemporaries."
