The body is, so to speak, melted and dissolved in a soft bed where one sinks into feathers and eider-down. The reins when too warmly covered become inflamed. Stone and other diseases are often due to this, and it invariably produces a delicate constitution, which is the seed-ground of every ailment.

The best bed is that in which we get the best sleep. Emile and I will prepare such a bed for ourselves during the daytime. We do not need Persian slaves to make our beds; when we are digging the soil we are turning our mattresses. I know that a healthy child may be made to sleep or wake almost at will. When the child is put to bed and his nurse grows weary of his chatter, she says to him, “Go to sleep.” That is much like saying, “Get well,” when he is ill. The right way is to let him get tired of himself. Talk so much that he is compelled to hold his tongue, and he will soon be asleep. Here is at least one use for sermons, and you may as well preach to him as rock his cradle; but if you use this narcotic at night, do not use it by day.

I shall sometimes rouse Emile, not so much to prevent his sleeping too much, as to accustom him to anything—even to waking with a start. Moreover, I should be unfit for my business if I could not make him wake himself, and get up, so to speak, at my will, without being called.

If he wakes too soon, I shall let him look forward to a tedious morning, so that he will count as gain any time he can give to sleep. If he sleeps too late I shall show him some favourite toy when he wakes. If I want him to wake at a given hour I shall say, “To-morrow at six I am going fishing,” or “I shall take a walk to such and such a place. Would you like to come too?” He assents, and begs me to wake him. I promise, or do not promise, as the case requires. If he wakes too late, he finds me gone. There is something amiss if he does not soon learn to wake himself.

Moreover, should it happen, though it rarely does, that a sluggish child desires to stagnate in idleness, you must not give way to this tendency, which might stupefy him entirely, but you must apply some stimulus to wake him. You must understand that is no question of applying force, but of arousing some appetite which leads to action, and such an appetite, carefully selected on the lines laid down by nature, kills two birds with one stone.

If one has any sort of skill, I can think of nothing for which a taste, a very passion, cannot be aroused in children, and that without vanity, emulation, or jealousy. Their keenness, their spirit of imitation, is enough of itself; above all, there is their natural liveliness, of which no teacher so far has contrived to take advantage. In every game, when they are quite sure it is only play, they endure without complaint, or even with laughter, hardships which they would not submit to otherwise without floods of tears. The sports of the young savage involve long fasting, blows, burns, and fatigue of every kind, a proof that even pain has a charm of its own, which may remove its bitterness. It is not every master, however, who knows how to season this dish, nor can every scholar eat it without making faces. However, I must take care or I shall be wandering off again after exceptions.

It is not to be endured that man should become the slave of pain, disease, accident, the perils of life, or even death itself; the more familiar he becomes with these ideas the sooner he will be cured of that over-sensitiveness which adds to the pain by impatience in bearing it; the sooner he becomes used to the sufferings which may overtake him, the sooner he shall, as Montaigne has put it, rob those pains of the sting of unfamiliarity, and so make his soul strong and invulnerable; his body will be the coat of mail which stops all the darts which might otherwise find a vital part. Even the approach of death, which is not death itself, will scarcely be felt as such; he will not die, he will be, so to speak, alive or dead and nothing more. Montaigne might say of him as he did of a certain king of Morocco, “No man ever prolonged his life so far into death.” A child serves his apprenticeship in courage and endurance as well as in other virtues; but you cannot teach children these virtues by name alone; they must learn them unconsciously through experience.

But speaking of death, what steps shall I take with regard to my pupil and the smallpox? Shall he be inoculated in infancy, or shall I wait till he takes it in the natural course of things? The former plan is more in accordance with our practice, for it preserves his life at a time when it is of greater value, at the cost of some danger when his life is of less worth; if indeed we can use the word danger with regard to inoculation when properly performed.

But the other plan is more in accordance with our general principles—to leave nature to take the precautions she delights in, precautions she abandons whenever man interferes. The natural man is always ready; let nature inoculate him herself, she will choose the fitting occasion better than we.

Do not think I am finding fault with inoculation, for my reasons for exempting my pupil from it do not in the least apply to yours. Your training does not prepare them to escape catching smallpox as soon as they are exposed to infection. If you let them take it anyhow, they will probably die. I perceive that in different lands the resistance to inoculation is in proportion to the need for it; and the reason is plain. So I scarcely condescend to discuss this question with regard to Emile. He will be inoculated or not according to time, place, and circumstances; it is almost a matter of indifference, as far as he is concerned. If it gives him smallpox, there will be the advantage of knowing what to expect, knowing what the disease is; that is a good thing, but if he catches it naturally it will have kept him out of the doctor’s hands, which is better.
