Epictetus, Golden Sayings 116

"But to marry and to rear offspring," said the young man, "will the Cynic hold himself bound to undertake this as a chief duty?" 

Grant me a republic of wise men, answered Epictetus, and perhaps none will lightly take the Cynic life upon him. For on whose account should he embrace that method of life? 

Suppose however that he does, there will then be nothing to hinder his marrying and rearing offspring. For his wife will be even such another as himself, and likewise her father; and in like manner will his children be brought up.

But in the present condition of things, which resembles an army in battle array, ought not the Cynic to be free from all distraction and given wholly to the service of God, so that he can go in and out among men, neither fettered by the duties, nor entangled by the relations of common life? 

For if he transgress them, he will forfeit the character of a good man and true; whereas if he observes them, there is an end to him as the Messenger, the Spy, the Herald of the Gods!
