As he acquires knowledge, choose what ideas he shall attach to it; as his passions awake, select scenes calculated to repress them. A veteran, as distinguished for his character as for his courage, once told me that in early youth his father, a sensible man but extremely pious, observed that through his growing sensibility he was attracted by women, and spared no pains to restrain him; but at last when, in spite of all his care, his son was about to escape from his control, he decided to take him to a hospital, and, without telling him what to expect, he introduced him into a room where a number of wretched creatures were expiating, under a terrible treatment, the vices which had brought them into this plight. This hideous and revolting spectacle sickened the young man. “Miserable libertine,” said his father vehemently, “begone; follow your vile tastes; you will soon be only too glad to be admitted to this ward, and a victim to the most shameful sufferings, you will compel your father to thank God when you are dead.”

These few words, together with the striking spectacle he beheld, made an impression on the young man which could never be effaced. Compelled by his profession to pass his youth in garrison, he preferred to face all the jests of his comrades rather than to share their evil ways. “I have been a man,” he said to me, “I have had my weaknesses, but even to the present day the sight of a harlot inspires me with horror.” Say little to your pupil, but choose time, place, and people; then rely on concrete examples for your teaching, and be sure it will take effect.

The way childhood is spent is no great matter; the evil which may find its way is not irremediable, and the good which may spring up might come later. But it is not so in those early years when a youth really begins to live. This time is never long enough for what there is to be done, and its importance demands unceasing attention; this is why I lay so much stress on the art of prolonging it. One of the best rules of good farming is to keep things back as much as possible. Let your progress also be slow and sure; prevent the youth from becoming a man all at once. While the body is growing the spirits destined to give vigour to the blood and strength to the muscles are in process of formation and elaboration. If you turn them into another channel, and permit that strength which should have gone to the perfecting of one person to go to the making of another, both remain in a state of weakness and the work of nature is unfinished. The workings of the mind, in their turn, are affected by this change, and the mind, as sickly as the body, functions languidly and feebly. Length and strength of limb are not the same thing as courage or genius, and I grant that strength of mind does not always accompany strength of body, when the means of connection between the two are otherwise faulty. But however well planned they may be, they will always work feebly if for motive power they depend upon an exhausted, impoverished supply of blood, deprived of the substance which gives strength and elasticity to all the springs of the machinery. There is generally more vigour of mind to be found among men whose early years have been preserved from precocious vice, than among those whose evil living has begun at the earliest opportunity; and this is no doubt the reason why nations whose morals are pure are generally superior in sense and courage to those whose morals are bad. The latter shine only through I know not what small and trifling qualities, which they call wit, sagacity, cunning; but those great and noble features of goodness and reason, by which a man is distinguished and honoured through good deeds, virtues, really useful efforts, are scarcely to be found except among the nations whose morals are pure.

Teachers complain that the energy of this age makes their pupils unruly; I see that it is so, but are not they themselves to blame? When once they have let this energy flow through the channel of the senses, do they not know that they cannot change its course? Will the long and dreary sermons of the pedant efface from the mind of his scholar the thoughts of pleasure when once they have found an entrance; will they banish from his heart the desires by which it is tormented; will they chill the heat of a passion whose meaning the scholar realises? Will not the pupil be roused to anger by the obstacles opposed to the only kind of happiness of which he has any notion? And in the harsh law imposed upon him before he can understand it, what will he see but the caprice and hatred of a man who is trying to torment him? Is it strange that he rebels and hates you too?

I know very well that if one is easy-going one may be tolerated, and one may keep up a show of authority. But I fail to see the use of an authority over the pupil which is only maintained by fomenting the vices it ought to repress; it is like attempting to soothe a fiery steed by making it leap over a precipice.

Far from being a hindrance to education, this enthusiasm of adolescence is its crown and coping-stone; this it is that gives you a hold on the youth’s heart when he is no longer weaker than you. His first affections are the reins by which you control his movements; he was free, and now I behold him in your power. So long as he loved nothing, he was independent of everything but himself and his own necessities; as soon as he loves, he is dependent on his affections. Thus the first ties which unite him to his species are already formed. When you direct his increasing sensibility in this direction, do not expect that it will at once include all men, and that the word “mankind” will have any meaning for him. Not so; this sensibility will at first confine itself to those like himself, and these will not be strangers to him, but those he knows, those whom habit has made dear to him or necessary to him, those who are evidently thinking and feeling as he does, those whom he perceives to be exposed to the pains he has endured, those who enjoy the pleasures he has enjoyed; in a word, those who are so like himself that he is the more disposed to self-love. It is only after long training, after much consideration as to his own feelings and the feelings he observes in others, that he will be able to generalise his individual notions under the abstract idea of humanity, and add to his individual affections those which may identify him with the race.

When he becomes capable of affection, he becomes aware of the affection of others, [Footnote: Affection may be unrequited; not so friendship. Friendship is a bargain, a contract like any other; though a bargain more sacred than the rest. The word “friend” has no other correlation. Any man who is not the friend of his friend is undoubtedly a rascal; for one can only obtain friendship by giving it, or pretending to give it.] and he is on the lookout for the signs of that affection. Do you not see how you will acquire a fresh hold on him? What bands have you bound about his heart while he was yet unaware of them! What will he feel, when he beholds himself and sees what you have done for him; when he can compare himself with other youths, and other tutors with you! I say, “When he sees it,” but beware lest you tell him of it; if you tell him he will not perceive it. If you claim his obedience in return for the care bestowed upon him, he will think you have over-reached him; he will see that while you profess to have cared for him without reward, you meant to saddle him with a debt and to bind him to a bargain which he never made. In vain you will add that what you demand is for his own good; you demand it, and you demand it in virtue of what you have done without his consent. When a man down on his luck accepts the shilling which the sergeant professes to give him, and finds he has enlisted without knowing what he was about, you protest against the injustice; is it not still more unjust to demand from your pupil the price of care which he has not even accepted!

Ingratitude would be rarer if kindness were less often the investment of a usurer. We love those who have done us a kindness; what a natural feeling! Ingratitude is not to be found in the heart of man, but self-interest is there; those who are ungrateful for benefits received are fewer than those who do a kindness for their own ends. If you sell me your gifts, I will haggle over the price; but if you pretend to give, in order to sell later on at your own price, you are guilty of fraud; it is the free gift which is beyond price. The heart is a law to itself; if you try to bind it, you lose it; give it its liberty, and you make it your own.

When the fisherman baits his line, the fish come round him without suspicion; but when they are caught on the hook concealed in the bait, they feel the line tighten and they try to escape. Is the fisherman a benefactor? Is the fish ungrateful? Do we find a man forgotten by his benefactor, unmindful of that benefactor? On the contrary, he delights to speak of him, he cannot think of him without emotion; if he gets a chance of showing him, by some unexpected service, that he remembers what he did for him, how delighted he is to satisfy his gratitude; what a pleasure it is to earn the gratitude of his benefactor. How delightful to say, “It is my turn now.” This is indeed the teaching of nature; a good deed never caused ingratitude.

If therefore gratitude is a natural feeling, and you do not destroy its effects by your blunders, be sure your pupil, as he begins to understand the value of your care for him, will be grateful for it, provided you have not put a price upon it; and this will give you an authority over his heart which nothing can overthrow. But beware of losing this advantage before it is really yours, beware of insisting on your own importance. Boast of your services and they become intolerable; forget them and they will not be forgotten. Until the time comes to treat him as a man let there be no question of his duty to you, but his duty to himself. Let him have his freedom if you would make him docile; hide yourself so that he may seek you; raise his heart to the noble sentiment of gratitude by only speaking of his own interest. Until he was able to understand I would not have him told that what was done was for his good; he would only have understood such words to mean that you were dependent on him and he would merely have made you his servant. But now that he is beginning to feel what love is, he also knows what a tender affection may bind a man to what he loves; and in the zeal which keeps you busy on his account, he now sees not the bonds of a slave, but the affection of a friend. Now there is nothing which carries so much weight with the human heart as the voice of friendship recognised as such, for we know that it never speaks but for our good. We may think our friend is mistaken, but we never believe he is deceiving us. We may reject his advice now and then, but we never scorn it.
