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.
