There is a singular parallel in psychical life: the man will have an infinitely more complex life than the child; but for him, too, there should always be a correspondence between the needs of his nature and the manner in which his spirit is nourished. A rule of internal life will always promote the health of the man.
Turning to attention, the primitive fact of correspondence between nature and stimulus which is the fundamental of life should prevail, however modified, when dealing with older children, and should remain the basis of education.
I am prepared for the objections of "experts." Children must be accustomed to pay attention to everything, even to things which are distasteful to them, because practical life demands such efforts.
The objection is based on a prejudice analogous to that which at one time made good fathers of families say: "Children should be accustomed to eat everything." In just the same way, moral training is put outside its rightful sphere—a fatal confusion. When ideas of this order, now happily obsolete, obtained, fathers would allow their children to fast all day, if they refused a dish they disliked at the mid-day meal, forbidding them anything but the rejected portion, which became ever colder and more disgusting, until at last hunger weakened the child's will and destroyed his caprice, and the plateful of cold food was swallowed. Thus, argued such a father, in the various circumstances in which he may be placed throughout his life, my son will be ready to eat whatever comes to hand, and will not be greedy and capricious. In those days also, sweets were forbidden to children (whose organisms require sugar, because the muscles consume a great deal of this during growth), in order to teach them to overcome greediness, and an easy and convenient method of correcting naughty children was to "send them to bed without any supper."
Very similar methods are now adopted by those who insist that children should pay attention to things they dislike, in order to accustom them to the necessities of life. But as in the case of psychical nourishment hunger is never brought to bear upon the "cold and distasteful viands," the indigestible and heavy food weakens and poisons the unwilling recipient.
Not thus shall we prepare the robust spirit, ready for all the difficult eventualities of life. The boy who swallowed the cold soup and went fasting to bed was the one whose body developed badly, who was too weak to resist infection when he encountered it, and fell ill; and morally it was he who, having a store of unsatisfied appetites within him, looked upon it as the greatest joy of his liberty, when he became an adult, to eat and drink to excess. How unlike was he to the boy of to-day, who, rationally fed and made robust of body, becomes the abstemious man, who eats to live in health, and combats alcoholism and excessive and injurious feeding; the modern man, who can defend himself by so many means against infectious diseases, and who is so ready for effort that, without any compulsion, he braves the arduous exertion of sport, and attempts and carries out great enterprises, such as the discovery of the Poles and the ascent of lofty mountains.
So, too, the man capable of braving the icy wastes of moral conflict, of undertaking spiritual ascents, will be he whose will is strong, whose spirit is well balanced, whose decisions are prompt and stedfast.
And the more a man's inner life shall have grown normally, organizing itself in accordance with the provident laws of nature, and forming an individuality, the more richly will he be endowed with a strong will and a well-balanced mind. To be ready for a struggle, it is not necessary to have struggled from one's birth, but it is necessary to be strong. He who is strong is ready; no hero was a hero before he had performed his heroic deed. The trials life has in store for us are unforeseen, unexpected; no one can prepare us directly to meet them; it is only a vigorous soul that can be prepared for everything.
When a living being is in process of evolution, it is essential to provide for the special requirements of the moment, in order to ensure its normal development. The fœtus must be nourished with blood; the new-born infant with milk. If during its intra-uterine life the fœtus should lack blood rich in albuminous substances and oxygen, or if poisonous substances should be introduced into its tissues, the living being will not develop normally, and no after-care will strengthen the man evolved from this impoverished source. Should the infant lack sufficient milk, the mal-nutrition of the initial stage of life condemns him to a permanent state of inferiority. The suckling "prepares himself to walk" by lying stretched out, and spending long, quiet hours in sleep. It is by sucking that the babe begins his teething. So, too, the fledgling in the nest does not prepare for flight by flying, but remains motionless in the little warm shell where its food is provided. The preparations for life are indirect.
