But this would mean exposing the children of the Republic to contact with monomaniacs, half-wits, defectives? Well, what of it? The vast majority of them are already exposed to contact with half-wits in their own homes; they are taught the word of God by half-wits on Sundays; they will grow up into Knights of Pythias, Odd Fellows, Red Men and other such half-wits in the days to come. Moreover, as I have hinted, they are already face to face with half-wits in the actual schools, at least in three cases out of four. The problem before us is not to dispose of this fact, but to utilize it. We cannot hope to fill the schools with persons of high intelligence, for persons of high intelligence simply refuse to spend their lives teaching such banal things as spelling and arithmetic. Among the teachers male we may safely assume that 95 per cent. are of low mentality, else they would depart for more appetizing pastures. And even among the teachers female the best are inevitably weeded out by marriage, and only the worst (with a few romantic exceptions) survive. The task before us, as I say, is not to make a vain denial of this cerebral inferiority of the pedagogue, nor to try to combat and disguise it by concocting a mass of technical hocus-pocus, but to search out and put to use the value lying concealed in it. For even stupidity, it must be plain, has its uses in the world, and some of them are uses that intelligence cannot meet. One would not tell off a Galileo or a Pasteur to drive an ash-cart or an Ignatius Loyola to be a stockbroker, or a Brahms to lead the orchestra in a Broadway cabaret. By the same token, one would not ask a Herbert Spencer or a Duns Scotus to instruct sucklings. Such men would not only be wasted at the job; they would also be incompetent. The business of dealing with children, in fact, demands a certain childishness of mind. The best teacher, until one comes to adult pupils, is not the one who knows most, but the one who is most capable of reducing knowledge to that simple compound of the obvious and the wonderful which slips easiest into the infantile comprehension. A man of high intelligence, perhaps, may accomplish the thing by a conscious intellectual feat. But it is vastly easier to the man (or woman) whose habits of mind are naturally on the plane of a child’s. The best teacher of children, in brief, is one who is essentially child-like.
