There is peace in dungeons, but is that enough to make dungeons desirable? - Jean-Jacques Rousseau

"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."

We seek knowledge only because we desire enjoyment, and it is impossible to conceive why a person who has neither desires nor fears would take the trouble to reason.

Every man having been born free and master of himself, no one else may under any pretext whatever subject him without his consent. To assert that the son of a slave is born a slave is to assert that he is not born a man.
