I know beforehand what you will say. You will not assert that the child has more needs than I attribute to him, but you will deny his strength. You forget that I am speaking of my own pupil, not of those puppets who walk with difficulty from one room to another, who toil indoors and carry bundles of paper. Manly strength, you say, appears only with manhood; the vital spirits, distilled in their proper vessels and spreading through the whole body, can alone make the muscles firm, sensitive, tense, and springy, can alone cause real strength. This is the philosophy of the study; I appeal to that of experience. In the country districts, I see big lads hoeing, digging, guiding the plough, filling the wine-cask, driving the cart, like their fathers; you would take them for grown men if their voices did not betray them. Even in our towns, iron-workers', tool makers', and blacksmiths' lads are almost as strong as their masters and would be scarcely less skilful had their training begun earlier. If there is a difference, and I do not deny that there is, it is, I repeat, much less than the difference between the stormy passions of the man and the few wants of the child. Moreover, it is not merely a question of bodily strength, but more especially of strength of mind, which reinforces and directs the bodily strength.
This interval in which the strength of the individual is in excess of his wants is, as I have said, relatively though not absolutely the time of greatest strength. It is the most precious time in his life; it comes but once; it is very short, all too short, as you will see when you consider the importance of using it aright.
He has, therefore, a surplus of strength and capacity which he will never have again. What use shall he make of it? He will strive to use it in tasks which will help at need. He will, so to speak, cast his present surplus into the storehouse of the future; the vigorous child will make provision for the feeble man; but he will not store his goods where thieves may break in, nor in barns which are not his own. To store them aright, they must be in the hands and the head, they must be stored within himself. This is the time for work, instruction, and inquiry. And note that this is no arbitrary choice of mine, it is the way of nature herself.
Human intelligence is finite, and not only can no man know everything, he cannot even acquire all the scanty knowledge of others. Since the contrary of every false proposition is a truth, there are as many truths as falsehoods. We must, therefore, choose what to teach as well as when to teach it. Some of the information within our reach is false, some is useless, some merely serves to puff up its possessor. The small store which really contributes to our welfare alone deserves the study of a wise man, and therefore of a child whom one would have wise. He must know not merely what is, but what is useful.
From this small stock we must also deduct those truths which require a full grown mind for their understanding, those which suppose a knowledge of man's relations to his fellow-men—a knowledge which no child can acquire; these things, although in themselves true, lead an inexperienced mind into mistakes with regard to other matters.
We are now confined to a circle, small indeed compared with the whole of human thought, but this circle is still a vast sphere when measured by the child's mind. Dark places of the human understanding, what rash hand shall dare to raise your veil? What pitfalls does our so-called science prepare for the miserable child. Would you guide him along this dangerous path and draw the veil from the face of nature? Stay your hand. First make sure that neither he nor you will become dizzy. Beware of the specious charms of error and the intoxicating fumes of pride. Keep this truth ever before you—Ignorance never did any one any harm, error alone is fatal, and we do not lose our way through ignorance but through self-confidence.
His progress in geometry may serve as a test and a true measure of the growth of his intelligence, but as soon as he can distinguish between what is useful and what is useless, much skill and discretion are required to lead him towards theoretical studies. For example, would you have him find a mean proportional between two lines, contrive that he should require to find a square equal to a given rectangle; if two mean proportionals are required, you must first contrive to interest him in the doubling of the cube. See how we are gradually approaching the moral ideas which distinguish between good and evil. Hitherto we have known no law but necessity, now we are considering what is useful; we shall soon come to what is fitting and right.
Man's diverse powers are stirred by the same instinct. The bodily activity, which seeks an outlet for its energies, is succeeded by the mental activity which seeks for knowledge. Children are first restless, then curious; and this curiosity, rightly directed, is the means of development for the age with which we are dealing. Always distinguish between natural and acquired tendencies. There is a zeal for learning which has no other foundation than a wish to appear learned, and there is another which springs from man's natural curiosity about all things far or near which may affect himself. The innate desire for comfort and the impossibility of its complete satisfaction impel him to the endless search for fresh means of contributing to its satisfaction. This is the first principle of curiosity; a principle natural to the human heart, though its growth is proportional to the development of our feeling and knowledge. If a man of science were left on a desert island with his books and instruments and knowing that he must spend the rest of his life there, he would scarcely trouble himself about the solar system, the laws of attraction, or the differential calculus. He might never even open a book again; but he would never rest till he had explored the furthest corner of his island, however large it might be. Let us therefore omit from our early studies such knowledge as has no natural attraction for us, and confine ourselves to such things as instinct impels us to study.
Our island is this earth; and the most striking object we behold is the sun. As soon as we pass beyond our immediate surroundings, one or both of these must meet our eye. Thus the philosophy of most savage races is mainly directed to imaginary divisions of the earth or to the divinity of the sun.
What a sudden change you will say. Just now we were concerned with what touches ourselves, with our immediate environment, and all at once we are exploring the round world and leaping to the bounds of the universe. This change is the result of our growing strength and of the natural bent of the mind. While we were weak and feeble, self-preservation concentrated our attention on ourselves; now that we are strong and powerful, the desire for a wider sphere carries us beyond ourselves as far as our eyes can reach. But as the intellectual world is still unknown to us, our thoughts are bounded by the visible horizon, and our understanding only develops within the limits of our vision.
Let us transform our sensations into ideas, but do not let us jump all at once from the objects of sense to objects of thought. The latter are attained by means of the former. Let the senses be the only guide for the first workings of reason. No book but the world, no teaching but that of fact. The child who reads ceases to think, he only reads. He is acquiring words not knowledge.
Teach your scholar to observe the phenomena of nature; you will soon rouse his curiosity, but if you would have it grow, do not be in too great a hurry to satisfy this curiosity. Put the problems before him and let him solve them himself. Let him know nothing because you have told him, but because he has learnt it for himself. Let him not be taught science, let him discover it. If ever you substitute authority for reason he will cease to reason; he will be a mere plaything of other people's thoughts.
You wish to teach this child geography and you provide him with globes, spheres, and maps. What elaborate preparations! What is the use of all these symbols; why not begin by showing him the real thing so that he may at least know what you are talking about?
One fine evening we are walking in a suitable place where the wide horizon gives us a full view of the setting sun, and we note the objects which mark the place where it sets. Next morning we return to the same place for a breath of fresh air before sun-rise. We see the rays of light which announce the sun's approach;
