bodies, he would not even know he had a body, what his hands handled would be in his brain alone; all his sensations would be united in one place, they would exist only in the common "sensorium," he would have only one idea, that of self, to which he would refer all his sensations; and this idea, or rather this feeling, would be the only thing in which he excelled an ordinary child.
This man, full grown at birth, would also be unable to stand on his feet, he would need a long time to learn how to keep his balance; perhaps he would not even be able to try to do it, and you would see the big strong body left in one place like a stone, or creeping and crawling like a young puppy.
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 us 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,14 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
