Hold childhood in reverence, and do not be in any hurry to judge it for good or ill. Leave exceptional cases to show themselves, let their qualities be tested and confirmed, before special methods are adopted. Give nature time to work before you take over her business, lest you interfere with her dealings. You assert that you know the value of time and are afraid to waste it. You fail to perceive that it is a greater waste of time to use it ill than to do nothing, and that a child ill taught is further from virtue than a child who has learnt nothing at all. You are afraid to see him spending his early years doing nothing. What! is it nothing to be happy, nothing to run and jump all day? He will never be so busy again all his life long. 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.The apparent ease with which children learn is their ruin. You fail to see that this very facility proves that they are not learning. Their shining, polished brain reflects, as in a mirror, the things you show them, but nothing sinks in. The child remembers the words and the ideas are reflected back; his hearers understand them, but to him they are meaningless.Although memory and reason are wholly different faculties, the one does not really develop apart from the other. Before the age of reason the child receives images, not ideas; and there is this difference between them: images are merely the pictures of external objects, while ideas are notions about those objects determined by their relations.

~ Jean-Jacques Rousseau

Such is the pure movement of nature prior to all reflection. Such is the force of natural pity, which the most depraved mores still have difficulty destroying, since everyday one sees in our theaters someone affected and weeping at the ills of some unfortunate person, and who, were he in the tyrant's place, would intensify the torments of his enemy still more; [like the bloodthirsty Sulla, so sensitive to ills he had not caused, or like Alexander of Pherae, who did not dare attend the performance of any tragedy, for fear of being seen weeping with Andromache and Priam, and yet who listened impassively to the cries of so many citizens who were killed everyday on his orders. Nature, in giving men tears, bears witness that she gave the human race the softest hearts.] Mandeville has a clear awareness that, with all their mores, men would never have been anything but monsters, if nature had not given them pity to aid their reason; but he has not seen that from this quality alone flow all the social virtues that he wants to deny in men. In fact, what are generosity, mercy, and humanity, if not pity applied to the weak, to the guilty, or to the human species in general. Benevolence and even friendship are, properly understood, the products of a constant pity fixed on a particular object; for is desiring that someone not suffer anything but desiring that he be happy?
