How can we dare to predict the behavior of man? We may predict the movements of a machine, of an automaton; more than this, we many even try to predict the mechanisms or "dynamisms" of the human psyche as well. But man is more than psyche.

I want you to listen to what your conscience commands you to do and go on to carry it out to the best of your knowledge. Then you will live to see that in the long run- in the long run, I say! - success will follow you precisely because you had forgotten to think of it.

The struggle for existence is a struggle 'for' something; it is purposeful and only in so being is it meaningful and able to bring meaning into life.

When a man finds that it is his destiny to suffer, he will have to accept his suffering as his task. . . . He will have to acknowledge the fact that even in suffering he is unique and alone in the universe. No one can relieve him of his suffering or suffer in his place. His unique opportunity lies in the way in which he bears his burden.

Man can only find meaning for his existence in something outside himself.
