"Unless a man has pity he is not truly a man. If man has not wept at the world's pain he is only half a man, and there will always be pain in the world. Knowing this does not mean that a man shall despair."

"I wanted him to know that each of you will truly be human when, in spite of your natural dislike of one another, you still respect one another. That is what it means to be civilized - that is what we are to learn from a study of ancient history."
