From "The Rhythmic Claims of Freedom and Discipline", in The Aims of Education:
We must take it as an unavoidable fact, that God has so made the world that there are more topics desirable for knowledge than any one person can possibly acquire. It is hopeless to approach the problem by the way of the enumeration of subjects which every one ought to have mastered. There are too many of them, all with excellent title-deeds. Perhaps, after all, this plethora of material is fortunate; for the world is made interesting by a delightful ignorance of important truths.
