Hitherto, the only defence ever made of our school-course leading up to residence at a University, has been that it aims not at giving knowledge but at training the mind. Youths then are supposed to be engaged, not in gaining knowledge, but in training their faculties for adult life. But when we come to provide for the “education” of children, we never think of training their faculties for youth, but endeavour solely to inculcate what will then come in useful. We see clearly enough that it would be absurd to cram the mind of a youth with laws of science or art or commerce which he could not understand, on the ground that the getting-up of these things might save him trouble in after-life. But we do not hesitate to sacrifice childhood to the learning by heart of grammar rules, Latin declensions, historical dates, and the like, with no thought whatever of the child’s faculties, but simply with a view of giving him knowledge (so-called) that will come in useful five or six years afterwards. We do not treat youths thus, probably because we have more sympathy with them, or at least understand them better. The intellectual life to which the senses and the imagination are subordinated in the man has already begun in the youth. In an inferior degree he can do what the man can do, and understand what the man can understand. He has already some notion of reasoning, and abstraction, and generalisation. But with the child it is very different. His active faculties may be said almost to differ in kind from a man’s. He has a feeling for the sensuous world which he will lose as he grows up. His strong imagination, under no control of the reason, is constantly at work building castles in the air, and investing the doll or the puppet-show with all the properties of the things they represent. His feelings and affections, easily excited, find an object to love or dislike in every person and thing he meets with. On the other hand, he has only vague notions of the abstract, and has no interest except in actual known persons, animals, and things. § 108. There is, then, between the child of eight or nine and the youth of fourteen or fifteen a greater difference than between the youth and the man of twenty; and this demands a corresponding difference in their studies. And yet, as matters are carried on now, the child is too often kept to the drudgery of learning by rote mere collections of hard words, perhaps, too, in a foreign language: and absorbed in the present, he is not much comforted by the teacher’s assurance that “some day” these things will come in useful. § 109. How to educate the child is doubtless the most difficult problem of all, and it is generally allotted to those who are the least likely to find a satisfactory solution.
