The problem of education is twofold: first to know, and then to utter. Every one who lives any semblance of an inner life thinks more nobly and profoundly than he speaks; and the best of teachers can impart only broken images of the truth which they perceive. Speech which goes from one to another between two natures, and, what is worse, between two experiences, is doubly relative. The speaker buries his meaning; it is for the hearer to dig it up again; and all speech, written or spoken, is in a dead language until it finds a willing and prepared hearer.
