"Don't let yesterday take up too much of today."

The only justice is to follow the sincere intuition of the soul, angry or gentle.

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

Life is either a daring adventure or nothing at all.
