In the dawn of life, when memory and imagination have not begun to function, the child only attends to what affects its senses. His sense experiences are the raw material of thought; they should, therefore, be presented to him in fitting order, so that memory may at a future time present them in the same order to his understanding; but as he only attends to his sensations it is enough, at first, to show him clearly the connection between these sensations and the things which cause them. He wants to touch and handle everything; do not check these movements which teach him invaluable lessons. Thus he learns to perceive the heat, cold, hardness, softness, weight, or lightness of bodies, to judge their size and shape and all their physical properties, by looking, feeling, [Footnote: Of all the senses that of smell is the latest to develop in children up to two or three years of age they appear to be insensible of pleasant or unpleasant odours; in this respect they are as indifferent or rather as insensible as many animals.] listening, and, above all, by comparing sight and touch, by judging with the eye what sensation they would cause to his hand.

It is only by movement that we learn the difference between self and not self; it is only by our own movements that we gain the idea of space. The child has not this idea, so he stretches out his hand to seize the object within his reach or that which is a hundred paces from him. You take this as a sign of tyranny, an attempt to bid the thing draw near, or to bid you bring it. Nothing of the kind, it is merely that the object first seen in his brain, then before his eyes, now seems close to his arms, and he has no idea of space beyond his reach. Be careful, therefore, to take him about, to move him from place to place, and to let him perceive the change in his surroundings, so as to teach him to judge of distances.

When he begins to perceive distances then you must change your plan, and only carry him when you please, not when he pleases; for as soon as he is no longer deceived by his senses, there is another motive for his effort. This change is remarkable and calls for explanation.

The discomfort caused by real needs is shown by signs, when the help of others is required. Hence the cries of children; they often cry; it must be so. Since they are only conscious of feelings, when those feelings are pleasant they enjoy them in silence; when they are painful they say so in their own way and demand relief. Now when they are awake they can scarcely be in a state of indifference, either they are asleep or else they are feeling something.

All our languages are the result of art. It has long been a subject of inquiry whether there ever was a natural language common to all; no doubt there is, and it is the language of children before they begin to speak. This language is inarticulate, but it has tone, stress, and meaning. The use of our own language has led us to neglect it so far as to forget it altogether. Let us study children and we shall soon learn it afresh from them. Nurses can teach us this language; they understand all their nurslings say to them, they answer them, and keep up long conversations with them; and though they use words, these words are quite useless. It is not the hearing of the word, but its accompanying intonation that is understood.

To the language of intonation is added the no less forcible language of gesture. The child uses, not its weak hands, but its face. The amount of expression in these undeveloped faces is extraordinary; their features change from one moment to another with incredible speed. You see smiles, desires, terror, come and go like lightning; every time the face seems different. The muscles of the face are undoubtedly more mobile than our own. On the other hand the eyes are almost expressionless. Such must be the sort of signs they use at an age when their only needs are those of the body. Grimaces are the sign of sensation, the glance expresses sentiment.

As man’s first state is one of want and weakness, his first sounds are cries and tears. The child feels his needs and cannot satisfy them, he begs for help by his cries. Is he hungry or thirsty? there are tears; is he too cold or too hot? more tears; he needs movement and is kept quiet, more tears; he wants to sleep and is disturbed, he weeps. The less comfortable he is, the more he demands change. He has only one language because he has, so to say, only one kind of discomfort. In the imperfect state of his sense organs he does not distinguish their several impressions; all ills produce one feeling of sorrow.

These tears, which you think so little worthy of your attention, give rise to the first relation between man and his environment; here is forged the first link in the long chain of social order.

When the child cries he is uneasy, he feels some need which he cannot satisfy; you watch him, seek this need, find it, and satisfy it. If you can neither find it nor satisfy it, the tears continue and become tiresome. The child is petted to quiet him, he is rocked or sung to sleep; if he is obstinate, the nurse becomes impatient and threatens him; cruel nurses sometimes strike him. What strange lessons for him at his first entrance into life!

I shall never forget seeing one of these troublesome crying children thus beaten by his nurse. He was silent at once. I thought he was frightened, and said to myself, “This will be a servile being from whom nothing can be got but by harshness.” I was wrong, the poor wretch was choking with rage, he could not breathe, he was black in the face. A moment later there were bitter cries, every sign of the anger, rage, and despair of this age was in his tones. I thought he would die. Had I doubted the innate sense of justice and injustice in man’s heart, this one instance would have convinced me. I am sure that a drop of boiling liquid falling by chance on that child’s hand would have hurt him less than that blow, slight in itself, but clearly given with the intention of hurting him.
