Suppose that while we are studying the course of the sun, and the manner of finding where the east is, Émile all at once interrupts me, to ask, "What is the use of all this?" What an opportunity for a fine discourse! How many things I could tell him of in answering this question, especially if anybody were by to listen! I could mention the advantages of travel and of commerce; the peculiar products of each climate; the manners of different nations; the use of the calendar; the calculation of seasons in agriculture; the art of navigation, and the manner of travelling by sea, following the true course without knowing where we are. I might take up politics, natural history, astronomy, even ethics and international law, by way of giving my pupil an exalted idea of all these sciences, and a strong desire to learn them. When I have done, the boy will not have understood a single idea out of all my pedantic display. He would like to ask again, "What is the use of finding out where the east is?" but dares not, lest I might be angry. He finds it more to his interest to pretend to understand what he has been compelled to hear. This is not at all an uncommon case in superior education, so-called. But our Émile, brought up more like a rustic, and carefully taught to think very slowly, will not listen to all this. He will run away at the first word he does not understand, and play about the room, leaving me to harangue all by myself. Let us find a simpler way; this scientific display does him no good. We were noticing the position of the forest north of Montmorency, when he interrupted me with the eager question, "What is the use of knowing that?" "You may be right," said I; "we must take time to think about it; and if there is really no use in it, we will not try it again, for we have enough to do that is of use." We went at something else, and there was no more geography that day. The next morning I proposed a walk before breakfast. Nothing could have pleased him better; children are always ready to run about, and this boy had sturdy legs of his own. We went into the forest, and wandered over the fields; we lost ourselves, having no idea where we were; and when we intended to go home, could not find our way. Time passed; the heat of the day came on; we were hungry. In vain did we hurry about from place to place; we found everywhere nothing but woods, quarries, plains, and not a landmark that we knew. Heated, worn out with fatigue, and very hungry, our running about only led us more and more astray. At last we sat down to rest and to think the matter over. Émile, like any other child, did not think about it; he cried. He did not know that we were near the gate of Montmorency, and that only a narrow strip of woodland hid it from us. But to him this narrow strip of woodland was a whole forest; one of his stature would be lost to sight among bushes. After some moments of silence I said to him, with a troubled air,
