“ Every addition to true knowledge is an addition to human power. ”
Doing nothing for others is the undoing of ourselves.
~ Horace Mann
Be ashamed to die until you have won some victory for humanity.
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.
Ignorance breeds monsters to fill up the vacancies of the soul that are unoccupied by the verities of knowledge.
