When a child says, "I don't see why I have to know that; I can't remember it anyway," he is voicing a very reasonable protest. Of course, there are plenty of instances of wilful shirking, where a little effort can overcome the slackness of memory; but every teacher who is honest enough to reckon with himself knows he cannot give a sensible reason why things are to be taught which have so little to do with the child's life that to-morrow, or the day after examination, they will be forgotten; things which he himself could not remember were he not repeating them year in and year out, as a matter of his trade. And every teacher who has thought at all for himself about the essential nature of the young humanity he is dealing with, knows that six hours of daily herding and in-penning of young, active bodies and limbs, accompanied by the additional injunction that no feet are to be shuffled, no whispers exchanged, and no paper wads thrown, is a frightful violation of all the laws of young life. Any gardener who should attempt to raise healthy, beautiful, and fruitful plants by outraging all those plants' instinctive wants and searchings, would meet as his reward--sickly plants, ugly plants, sterile plants, dead plants. He will not do it; he will watch very carefully to see whether they like much sunlight, or considerable shade, whether they thrive on much water or get drowned in it, whether they like sandy soil, or fat mucky soil; the plant itself will indicate to him when he is doing the right thing. And every gardener will watch for indications with great anxiety. If he finds the plant revolts against his experiments, he will desist at once, and try something else; if he finds it thrives, he will emphasize the particular treatment so long as it seems beneficial. But what he will surely not do, will be to prepare a certain area of ground all just alike, with equal chances of sun and amount of moisture in every part, and then plant everything together without discrimination,--mighty close together!--saying beforehand, "If plants don't want to thrive on this, they ought to want to; and if they are stubborn about it, they must be made to." Or if a raiser of animals were to start in feeding them on a regimen adapted not to their tastes but to his; if he were to insist on stuffing the young ones with food only fitted for the older ones; if he were to shut them up and compel them somehow to be silent, stiff, and motionless for hours together,--he would--well, he would very likely be arrested for cruelty to animals.
