He would feel the discomfort of bodily needs without knowing what was the matter and without knowing how to provide for these needs. There is no immediate connection between the muscles of the stomach and those of the arms and legs to make him take a step towards food, or stretch a hand to seize it, even were he surrounded with it; and as his body would be full grown and his limbs well developed he would be without the perpetual restlessness and movement of childhood, so that he might die of hunger without stirring to seek food. However little you may have thought about the order and development of our knowledge, you cannot deny that such a one would be in the state of almost primitive ignorance and stupidity natural to man before he has learnt anything from experience or from his fellows.

We know then, or we may know, the point of departure from which we each start towards the usual level of understanding; but who knows the other extreme? Each progresses more or less according to his genius, his taste, his needs, his talents, his zeal, and his opportunities for using them. No philosopher, so far as I know, has dared to say to man, "Thus far shalt thou go and no further." We know not what nature allows us to be, none of us has measured the possible difference between man and man. Is there a mind so dead that this thought has never kindled it, that has never said in his pride, "How much have I already done, how much more may I achieve? Why should I lag behind my fellows?"

As I said before, man's education begins at birth; before he can speak or understand he is learning. Experience precedes instruction; when he recognises his nurse he has learnt much. The knowledge of the most ignorant man would surprise us if we had followed his course from birth to the present time. If all human knowledge were divided into two parts, one common to all, the other peculiar to the learned, the latter would seem very small compared with the former. But we scarcely heed this general experience, because it is acquired before the age of reason. Moreover, knowledge only attracts attention by its rarity, as in algebraic equations common factors count for nothing. Even animals learn much. They have senses and must learn to use them; they have needs, they must learn to satisfy them; they must learn to eat, walk, or fly. Quadrupeds which can stand on their feet from the first cannot walk for all that; from their first attempts it is clear that they lack confidence. Canaries who escape from their cage are unable to fly, having never used their wings. Living and feeling creatures are always learning. If plants could walk they would need senses and knowledge, else their species would die out. The child's first mental experiences are purely affective, he is only aware of pleasure and pain; it takes him a long time to acquire the definite sensations which show him things outside himself, but before these things present and withdraw themselves, so to speak, from his sight, taking size and shape for him, the recurrence of emotional experiences is beginning to subject the child to the rule of habit. You see his eyes constantly follow the light, and if the light comes from the side the eyes turn towards it, so that one must be careful to turn his head towards the light lest he should squint. He must also be accustomed from the first to the dark, or he will cry if he misses the light. Food and sleep, too, exactly measured, become necessary at regular intervals, and soon desire is no longer the effect of need, but of habit, or rather habit adds a fresh need to those of nature. You must be on your guard against this.

The only habit the child should be allowed to contract is that of having no habits; let him be carried on either arm, let him be accustomed to offer either hand, to use one or other indifferently; let him not want to eat, sleep, or do anything at fixed hours, nor be unable to be left alone by day or night. Prepare the way for his control of his liberty and the use of his strength by leaving his body its natural habit, by making him capable of lasting self-control, of doing all that he wills when his will is formed.

As soon as the child begins to take notice, what is shown him must be carefully chosen. The natural man is interested in all new things. He feels so feeble that he fears the unknown: the habit of seeing fresh things without ill effects destroys this fear. Children brought up in clean houses where there are no spiders are afraid of spiders, and this fear often lasts through life. I never saw peasants, man, woman, or child, afraid of spiders.

Since the mere choice of things shown him may make the child timid or brave, why should not his education begin before he can speak or understand? I would have him accustomed to see fresh things, ugly, repulsive, and strange beasts, but little by little, and far off till he is used to them, and till having seen others handle them he handles them himself. If in childhood he sees toads, snakes, and crayfish, he will not be afraid of any animal when he is grown up. Those who are continually seeing terrible things think nothing of them.

All children are afraid of masks. I begin by showing Emile a mask with a pleasant face, then some one puts this mask before his face; I begin to laugh, they all laugh too, and the child with them. By degrees I accustom him to less pleasing masks, and at last hideous ones. If I have arranged my stages skilfully, far from being afraid of the last mask, he will laugh at it as he did at the first. After that I am not afraid of people frightening him with masks.

When Hector bids farewell to Andromache, the young Astyanax, startled by the nodding plumes on the helmet, does not know his father; he flings himself weeping upon his nurse's bosom and wins from his mother a smile mingled with tears. What must be done to stay this terror? Just what Hector did; put the helmet on the ground and caress the child. In a calmer moment one would do more; one would go up to the helmet, play with the plumes, let the child feel them; at last the nurse would take the helmet and place it laughingly on her own head, if indeed a woman's hand dare touch the armour of Hector.

If Emile must get used to the sound of a gun, I first fire a pistol with a small charge. He is delighted with this sudden flash, this sort of lightning; I repeat the process with more powder; gradually I add a small charge without a wad, then a larger; in the end I accustom him to the sound of a gun, to fireworks, cannon, and the most terrible explosions.

I have observed that children are rarely afraid of thunder unless the peals are really terrible and actually hurt the ear, otherwise this fear only comes to them when they know that thunder sometimes hurts or kills. When reason begins to cause fear, let use reassure them. By slow and careful stages man and child learn to fear nothing.

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.

This tendency to anger, vexation, and rage needs great care. Boerhaave thinks that most of the diseases of children are of the nature of convulsions, because the head being larger in proportion and the nervous system more extensive than in adults, they are more liable to nervous irritation. Take the greatest care to remove from them any servants who tease, annoy, or vex them. They are a hundredfold more dangerous and more fatal than fresh air and changing seasons. When children only experience resistance in things and never in the will of man, they do not become rebellious or passionate, and their health is better. This is one reason why the children of the poor, who are freer and more independent, are generally less frail and weakly, more vigorous than those who are supposed to be better brought up by being constantly thwarted; but you must always remember that it is one thing to refrain from thwarting them, but quite another to obey them. The child's first tears are prayers, beware lest they become commands; he begins by asking for aid, he ends by demanding service. Thus from his own weakness, the source of his first consciousness of dependence, springs the later idea of rule and tyranny; but as this idea is aroused rather by his needs than by our services, we begin to see moral results whose causes are not in nature; thus we see how important it is, even at the earliest age, to discern the secret meaning of the gesture or cry.

When the child tries to seize something without speaking, he thinks he can reach the object, for he does not rightly judge its distance; when he cries and stretches out his hands he no longer misjudges the distance, he bids the object approach, or orders you to bring it to him. In the first case bring it to him slowly; in the second do not even seem to hear his cries. The more he cries the less you should heed him. He must learn in good time not to give commands to men, for he is not their master, nor to things, for they cannot hear him. Thus when the child wants something you mean to give him, it is better to carry him to it rather than to bring the thing to him. From this he will draw a conclusion suited to his age, and there is no other way of suggesting it to him.

The Abbe Saint-Pierre calls men big children; one might also call children little men. These statements are true, but they require explanation. But when Hobbes calls the wicked a strong child, his statement is contradicted by facts. All wickedness comes from weakness. The child is only naughty because he is weak; make him strong and he will be good; if we could do everything we should never do wrong. Of all the attributes of the Almighty, goodness is that which it would be hardest to dissociate from our conception of Him. All nations who have acknowledged a good and an evil power, have always regarded the evil as inferior to the good; otherwise their opinion would have been absurd. Compare this with the creed of the Savoyard clergyman later on in this book.

Reason alone teaches us to know good and evil. Therefore conscience, which makes us love the one and hate the other, though it is independent of reason, cannot develop without it. Before the age of reason we do good or ill without knowing it, and there is no morality in our actions, although there is sometimes in our feeling with regard to other people's actions in relation to ourselves. A child wants to overturn everything he sees. He breaks and smashes everything he can reach; he seizes a bird as he seizes a stone, and strangles it without knowing what he is about.

Why so? In the first place philosophy will account for this by inbred sin, man's pride, love of power, selfishness, spite; perhaps it will say in addition to this that the child's consciousness of his own weakness makes him eager to use his strength, to convince himself of it. But watch that broken down old man reduced in the downward course of life to the weakness of a child; not only is he quiet and peaceful, he would have all about him quiet and peaceful too; the least change disturbs and troubles him, he would like to see universal calm. How is it possible that similar feebleness and similar passions should produce such different effects in age and in infancy, if the original cause were not different? And where can we find this difference in cause except in the bodily condition of the two. The active principle, common to both, is growing in one case and declining in the other; it is being formed in the one and destroyed in the other; one is moving towards life, the other towards death. The failing activity of the old man is centred in his heart, the child's overflowing activity spreads abroad. He feels, if we may say so, strong enough to give life to all about him. To make or to destroy, it is all one to him; change is what he seeks, and all change involves action. If he seems to enjoy destructive activity it is only that it takes time to make things and very little time to break them, so that the work of destruction accords better with his eagerness.

While the Author of nature has given children this activity, He takes care that it shall do little harm by giving them small power to use it. But as soon as they can think of people as tools to be used, they use them to carry out their wishes and to supplement their own weakness. This is how they become tiresome, masterful, imperious, naughty, and unmanageable; a development which does not spring from a natural love of power, but one which has been taught them, for it does not need much experience to realise how pleasant it is to set others to work and to move the world by a word.
