This comparison for purposes of understanding leads on to what psychologists call classification, or generalisation; the bringing together and keeping before the mind of a number of like things by help of a general name. The child may be said to become a true thinker as soon as he uses names intelligently, calling each thing by an appropriate name, and so classing it with its kind. This power of infantile generalisation is one full of interest and has been carefully observed. It will, however, be more conveniently dealt with in another chapter where we shall be specially concerned with the child’s use of language. While thus beginning to arrange things according to such points of likeness as he can discover, the child is noting the connexions of things. He finds out what belongs to a horse, to a locomotive engine, he notes when father leaves home and returns, when the sun declines, what accompanies and follows rain, and so forth. That is to say, he is feeling his way to the idea of connectedness, of regularity, of what we call uniformity or law. We now say that the child reasons, no longer blindly or automatically like the dog, but with a consciousness of what he is doing. We little think how much hard work has to be got through by the little brain before even this dim perception of regularity is attained. In some things, no doubt, the regularity is patent enough, and can hardly be overlooked by the dullest of children. The connexion between the laying of the cloth and the meal—at least in an orderly home—is a matter which even the canine and the feline intelligence is quite able to grasp. But when it comes to finding out the law according to which, say, his face gets dirty, his head aches, or people send out their invitations to children’s parties, the matter is not so simple. The fact is that there is so large a proportion of apparent disconnectedness and capricious irregularity in the child’s world that it is hard to see how he would ever learn to understand and to reason, were he not endowed with a lively and inextinguishable impulse to connect and simplify. Herein lies a part of the pathos of childhood. It brings its naïve prepossession of a regular well-ordered world, and alas, finds itself confronted with an impenetrable tangle of disorder. How quaint it is to listen to the little thinker, as, with untroubled brow, he begins to propound his beautifully simple theory of the cosmic order. An American boy of ten who had had one cross small teacher, and whose best teacher had been tall, accosted a new teacher thus: “I’m afraid you’ll make a cross teacher”. His teacher replied: “Why, am I cross?” To which he rejoined: “No; but you are so small”. We call this hasty generalisation. We might with equal propriety term it the child’s innate _a priori_ view of things.
