Diogenes was from Sinope, a Greek city on the coast of the Black Sea (in modern-day Turkey). His father was the official in charge of the mint at Sinope and supposedly got in trouble for issuing counterfeit coins. Diogenes may have been a misfit, but his father would have fit right in in modern-day Washington or Brussels.
An excellent point. Diogenes spent a good portion of his life in Corinth. He once told Alexander the Great to "stand out of my light." Can you imagine his fate if he said that to der Fuhrer.
