This is the first contest of the man who enters the world: he has to struggle with his parents, with those who have given him life. And this occurs because his infant life is "different" from that of his parents; the child has to form himself, whereas his parents are already formed. The child must move about a great deal, to coordinate his movements, which are not yet under control; the parents, on the other hand, have their voluntary mobility organized, and can control their movements; perhaps also they are often tired after their work. The child's senses are not yet fully developed; his powers of accommodation are insufficient, and need help from touching and feeling, in order to take account of objects as well as of spaces; and his eyes are rectified by the experience of his hands. The parents, on the contrary, have developed senses, and have already corrected the primitive illusions of these; their powers of accommodation are perfect, if they have not spoilt them by abuse; in every way cerebral activity leads the senses to receive an exact impression; they have no need to touch. Children are anxious to get knowledge of the external world; their parents know it too well already. Therefore they do not understand each other. Parents want their children to do as they do, and any diversity is called "naughtiness." Think of the mother who drags her child along with her; he has to run while she walks; his legs are short, while hers are long; weak, while hers are strong, he has to bear the weight of his body and his disproportionately large head, while the mother has a head and body which are proportionally lighter and smaller. The child is tired and stands and cries, and the mother exclaims, "Come on, you naughty little thing! I won't have any nonsense. Do you want me to carry you, lazybones? No, I won't give in to you." Or again, we see mothers who, when their children sit down on the ground--or lay themselves flat on their stomachs with their feet in the air, and support themselves on their elbows, while they look round them, call out, "Off the ground! You are making yourself dirty, naughty child." All this may be translated in this way: "The child is different from the adult. The formation of his body is such that his head and his body are enormously large in comparison with his small, slender legs, because they are the part which will grow most. Hence the child cannot endure walking, and prefers to lie at full length, which is the most healthy position for him. He has a wonderful tendency towards development; he gets his first ideas of external life and assists his senses of sight and hearing by touching, in order to realize the forms of objects and distance. He moves continually, because he must coordinate and adapt his mobility. Hence he moves a great deal, walks very little, throws himself on the ground, and touches everything, and these are signs that he is alive, and that he is growing." No--all this is looked upon as naughtiness.
