In conclusion, whatever food you give your children, provided you accustom them to nothing but plain and simple dishes, let them eat and run and play as much as they want; you may be sure they will never eat too much and will never have indigestion; but if you keep them hungry half their time, when they do contrive to evade your vigilance, they will take advantage of it as far as they can; they will eat till they are sick, they will gorge themselves till they can eat no more. Our appetite is only excessive because we try to impose on it rules other than those of nature, opposing, controlling, prescribing, adding, or substracting; the scales are always in our hands, but the scales are the measure of our caprices not of our stomachs. I return to my usual illustration; among peasants the cupboard and the apple-loft are always left open, and indigestion is unknown alike to children and grown-up people. If, however, it happened that a child were too great an eater, though, under my system, I think it is impossible, he is so easily distracted by his favourite games that one might easily starve him without his knowing it. How is it that teachers have failed to use such a safe and easy weapon. Herodotus records that the Lydians, [Footnote: The ancient historians are full of opinions which may be useful, even if the facts which they present are false. But we do not know how to make any real use of history. Criticism and erudition are our only care; as if it mattered more that a statement were true or false than that we should be able to get a useful lesson from it. A wise man should consider history a tissue of fables whose morals are well adapted to the human heart.] under the pressure of great scarcity, decided to invent sports and other amusements with which to cheat their hunger, and they passed whole days without thought of food. Your learned teachers may have read this passage time after time without seeing how it might be applied to children. One of these teachers will probably tell me that a child does not like to leave his dinner for his lessons. You are right, sir--I was not thinking of that sort of sport.
