Diogenes the Cynic was a philosopher of ancient Greece, known as a founder of the school of Cynicism. Although he supposedly authoured several books, no works of his survive to this day.
Diogenes was against the customs of the Greeks, and took his views to the extreme, living in a tub on the streets of Athens. The stories of Diogenes said that he would mock Greek custom whenever possible, eating in the marketplace where it was rude to do so, living in the streets with dogs, and wandering the streets with a lantern in broad daylight.
