Horace Mann

"Do not think of knocking out another person's brains because he differs in opinion from you. It would be as rational to knock yourself on the head because you differ from yourself ten years ago."

"Be ashamed to die until you have won some victory for humanity."

"Education...beyond all other devices of human origin, is a great equalizer of conditions of men --the balance wheel of the social machinery...It does better than to disarm the poor of their hostility toward the rich; it prevents being poor."

"Ignorance breeds monsters to fill up the vacancies of the soul that are unoccupied by the verities of knowledge."

"Doing nothing for others is the undoing of ourselves."

"A house without books is like a room without windows."
