When the child desires to touch and to act, in spite of "punishments of every kind," he persists in exercises necessary "to his development," and displays a strength of will in the matter against which we are often powerless; he shows the same persistence as in breathing, in crying when he is hungry, and in raising himself when he wants to walk. Thus the child turns to external objects which respond to his needs: if he finds them, he displays his powers in muscular or sensory exercises, and then he is joyous; and if he does not find them, he is restless as when his desires are unsatisfied. Toys are too light to satisfy arms which require to make the efforts necessary in lifting and moving objects; they are too complex to satisfy senses which need to analyze a single sensation. They are vanity, and in themselves they represent simulacra and parodies of actual life. And yet they form the world of our children, in which they are constrained to "consume" their potential powers in a continuous exasperation, which incites them to destroy things. Happily, children do not hear the pronouncement of the common formula, that children have an "instinct" for destruction. Nor are they familiar with the other axiom which contradicts this: That the instinct of "property," in other words, selfishness, is strongly developed in them. On the contrary, the child has merely the overpowering instinct to "grow," and therefore to raise and to perfect himself; in every period of life he seeks instinctively to prepare himself for the next period. This fact is very much more comprehensible than the strange instincts we calumniously attribute to him. Just try the experiment of allowing children to act for themselves; they are at once "transformed." In the Guerrieri Gonzaga Children's House, it sufficed to provide a comb, to transform the naughtiest, most rebellious of the children, the one whom the teacher designated as in need of "taming," into a lively and attractive little girl, who combed the hair of her companions most carefully, with evident delight. We had only to say to an awkward, lethargic child, who came forward holding out her arms to have her sleeves pulled down for her: "Do it yourself," and there was a flash of intelligence in her eyes, her weary face was lighted up by an expression of satisfied pride and amazement, and she began to pull down her sleeves with positive delight. When these children were given a little basin and a piece of soap, how carefully they emptied and replaced the receptacle, fearing to break it, and how caressingly they handled the soap, laying it down very gently! It seemed as if the task had been confided to a mechanism of moving figures, with an accompaniment of music: the figures were the children, the music was their own joy.
