Diogenes (c. 412- c. 323 B.C ) was a very playful philosopher; an irreverent Zennish character who lived a good thousand years before Zen was invented. He liked to use great wit when challenging the values and beliefs of his fellow citizens in ancient Athens. He lived in great poverty, probably begging and stealing his food, and steadfastly disdained all forms of luxury. It was because of his determination to follow his own dictates and not adhere to the conventions of society that he was given the epithet "dog," from which the name "cynic" is derived. Over the coming months I will share with you some of his wittiest and most profound teachings.
Here is the first offering:
"Why is it, Diogenes, that pupils leave you to go to other teachers, but rarely do they leave them to come to you?"
"Because," replied Diogenes, "one can make eunuchs out of men, but no one can make a man out of eunuchs".Source: David Quinn's home page (well worth a look)
