The real test of a man is not when he plays the role that he wants for himself but when he plays the role destiny has for him.

The deeper the experience of an absence of meaning - in other words, of absurdity - the more energetically meaning is sought.

Technological measures are important, but equally important is... a consciousness of the commonality of all living beings and an emphasis on shared responsibility.

There is only one thing I will not concede: that it might be meaningless to strive in a good cause.

You can't spend your whole life criticizing something and then, when you have the chance to do it better, refuse to go near it.

Work for something because it is good, not just because it stands a chance to succeed.

The tragedy of modern man is not that he knows less and less about the meaning of his own life, but that it bothers him less and less.
