When some people urged that it is impossible for man to live like the animals owing to the tenderness of his flesh and because he is naked and unprotected, [Diogenes] would say in reply that men are so very tender because of their mode of life. ... Man’s ingenuity and his discovering and contriving so many helps to life had not been altogether advantageous to later generations, since men do not employ their cleverness to promote courage or justice, but to procure pleasure.

Pleasure assails a man through each and every sense that he has; and while he must face and grapple with work, to pleasure he must give the widest berth possible and have none but unavoidable dealings with her. And herein the strongest man is indeed strongest, one might almost say, who can keep the farthest away from pleasures; for it is impossible to dwell with pleasure or even to dally with her for any length of time without being completely enslaved.

When [Diogenes] observed how other men were harassed throughout their whole lives, ever plotting against one another, ever encompassed by a thousand ills and never able to enjoy a moment’s rest, nay, not even during the great festivals nor when they proclaimed a truce; and when he beheld that they did or suffered all this simply in order to keep themselves alive, and that their greatest fear was lest their so-called necessities should fail them, and how, furthermore, they planned and strove to leave great riches to their children, he marvelled that he too did not do the like, but was the only independent man in the world.
