Slaves lose everything in chains, even the desire of escaping from them.

Political writers argue in regard to the love of liberty with the same philosophy that philosophers do in regard to the state of nature; by the things they see they judge of things very different which they have never seen, and they attribute to men a natural inclination to slavery, on account of the patience with which the slaves within their notice carry the yoke; not reflecting that it is with liberty as with innocence and virtue, the value of which is not known but by those who possess them, though the relish for them is lost with the things themselves. I know the charms of your country, said Brasidas to a satrap who was comparing the life of the Spartans with that of the Persepolites; but you can not know the pleasures of mine.

"Plato, in his Republic, which is considered so stern, teaches the children only through festivals, games, songs, and amusements. It seems as if he had accomplished his purpose when he had taught them to be happy; and Seneca, speaking of the Roman lads in olden days, says, "They were always on their feet, they were never taught anything which kept them sitting." Were they any the worse for it in manhood? Do not be afraid, therefore, of this so-called idleness. What would you think of a man who refused to sleep lest he should waste part of his life? You would say, "He is mad; he is not enjoying his life, he is robbing himself of part of it; to avoid sleep he is hastening his death." Remember that these two cases are alike, and that childhood is the sleep of reason."
