Thus in every branch of our education the day's curriculum must be arranged so as to occupy a boy's free time in profitable development of his physical powers. He has no right in those years to loaf about, becoming a nuisance in public streets and in cinemas; but when his day's work is done he ought to harden his young body so that his strength may not be found wanting when the occasion arises. To prepare for this and to carry it out should be the function of our educational system and not exclusively to pump in knowledge or wisdom. Our school system must also rid itself of the notion that the training of the body is a task that should be left to the individual himself. There is no such thing as allowing freedom of choice to sin against posterity and thus against the race.
