"A house without books is like a room without windows."
"Doing nothing for others is the undoing of ourselves."
"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."
