"I shall not take pains to prevent Emile hurting himself; far from it, I should be vexed if he never hurt himself, if he grew up unacquainted with pain. To bear pain is his first and most useful lesson. It seems as if children were small and weak on purpose to teach them these valuable lessons without danger. The child has such a little way to fall he will not break his leg; if he knocks himself with a stick he will not break his arm; if he seizes a sharp knife he will not grasp it tight enough to make a deep wound. So far as I know, no child, left to himself, has ever been known to kill or maim itself, or even to do itself any serious harm, unless it has been foolishly left on a high place, or alone near the fire, or within reach of dangerous weapons. What is there to be said for all the paraphernalia with which the child is surrounded to shield him on every side so that he grows up at the mercy of pain, with neither courage nor experience, so that he thinks he is killed by a pin-prick and faints at the sight of blood? With our foolish and pedantic methods we are always preventing children from learning what they could learn much better by themselves, while we neglect what we alone can teach them. Can anything be sillier than the pains taken to teach them to walk, as if there were any one who was unable to walk when he grows up through his nurse's neglect? Instead of keeping him mewed up in a stuffy room, take him out into a meadow every day; let him run about, let him struggle and fall again and again, the oftener the better; he will learn all the sooner to pick himself up. The delights of liberty will make up for many bruises. My pupil will hurt himself oftener than yours, but he will always be merry; your pupils may receive fewer injuries, but they are always thwarted, constrained, and sad. I doubt whether they are any better off."
