The explosive passions produce a great effect upon the child when he sees them; their outward expression is very marked; he is struck by this and his attention is arrested. Anger especially is so noisy in its rage that it is impossible not to perceive it if you are within reach. You need not ask yourself whether this is an opportunity for a pedagogue to frame a fine disquisition. What! no fine disquisition, nothing, not a word! Let the child come to you; impressed by what he has seen, he will not fail to ask you questions. The answer is easy; it is drawn from the very things which have appealed to his senses. He sees a flushed face, flashing eyes, a threatening gesture, he hears cries; everything shows that the body is ill at ease. Tell him plainly, without affectation or mystery, "This poor man is ill, he is in a fever." You may take the opportunity of giving him in a few words some idea of disease and its effects; for that too belongs to nature, and is one of the bonds of necessity which he must recognise. By means of this idea, which is not false in itself, may he not early acquire a certain aversion to giving way to excessive passions, which he regards as diseases; and do you not think that such a notion, given at the right moment, will produce a more wholesome effect than the most tedious sermon? But consider the after effects of this idea; you have authority, if ever you find it necessary, to treat the rebellious child as a sick child; to keep him in his room, in bed if need be, to diet him, to make him afraid of his growing vices, to make him hate and dread them without ever regarding as a punishment the strict measures you will perhaps have to use for his recovery. If it happens that you yourself in a moment's heat depart from the calm and self-control which you should aim at, do not try to conceal your fault, but tell him frankly, with a gentle reproach, "My dear, you have hurt me." Moreover, it is a matter of great importance that no notice should be taken in his presence of the quaint sayings which result from the simplicity of the ideas in which he is brought up, nor should they be quoted in a way he can understand. A foolish laugh may destroy six months' work and do irreparable damage for life. I cannot repeat too often that to control the child one must often control oneself. I picture my little Emile at the height of a dispute between two neighbours going up to the fiercest of them and saying in a tone of pity, "You are ill, I am very sorry for you." This speech will no doubt have its effect on the spectators and perhaps on the disputants. Without laughter, scolding, or praise I should take him away, willing or no, before he could see this result, or at least before he could think about it; and I should make haste to turn his thoughts to other things, so that he would soon forget all about it.
