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?
