Revenge... is like a rolling stone, which, when a man hath forced up a hill, will return upon him with a greater violence, and break those bones whose sinews gave it motion.

Why seeketh thou revenge, O man! with what purpose is it that thou pursuest it? Thinkest thou to pain thine adversary by it? Know that thou thyself feelest its greatest torments.

If a man loses his reverence for any part of life, he will lose his reverence for all of life.

Man must cease attributing his problems to his environment, and learn again to exercise his will - his personal responsibility in the realm of faith and morals

Until he extends the circle of his compassion to all living things, man will not himself find peace. - The Philosophy of Civilization.

Man is a clever aninmal who behaves like an imbecile.
