“He knew enough to be ignorant. His course had led him through oceans of ignorance; he had tumbled from one ocean into another till he had learned to swim; but even to him education was a serious thing. A parent gives life, but as parent, gives no more. A murderer takes life, but his deed stops there.
A teacher affects eternity; he can never tell where his influence stops. A teacher is expected to teach truth, and may perhaps flatter himself that he does so, if he stops with the alphabet or the multiplication table, as a mother teaches truth by making her child eat with a spoon; but morals are quite another truth and philosophy is more complex still.”
