In previous chapters, we have considered the education in character and knowledge which, in a good social system, should be open to everybody, and should in fact be enjoyed by everybody, except for serious special reasons such as musical genius. (It would have been unfortunate if Mozart had been obliged to learn ordinary school subjects up to the age of eighteen.) But even in an ideal community there would, I think, be many people who would not go to the university. I am convinced that, at present, only a minority of the population can profit by a scholastic education prolonged to the age of twenty-one or twenty-two. Certainly the idle rich who at present infest the older universities very often derive no benefit from them, but merely contract habits of dissipation. We have therefore to ask on what principle we are to select those who should go to the university. At present, they are in the main those whose parents can afford to send them, though this principle of selection is being increasingly modified by the scholarship system. Obviously, the principle of selection ought to be educational, not financial. A boy or girl of eighteen, who has had a good school education, is capable of doing useful work. If he or she is to be exempted for a further period of three or four years, the community has a right to expect that the time will be profitably employed. But before deciding who is to go to the university, we must have some view as to the function of the university in the life of the community.
