For me the Jewish religion like all other religions is an incarnation of the most childish superstitions.

All these primary impulses, not easily described in words, are the springs of man's actions.

Science can only ascertain what is, but not what should be, and outside of its domain value judgements of all kinds remain necessary.

Imagination is more valuable than information.

Man can find meaning in life only through devoting himself to society.

With me every peep becomes a trumpet solo.

Today we must abandon competition and secure cooperation. This must be the central fact in all our considerations of international affairs; otherwise we face certain disaster. Past thinking and methods did not prevent world wars. Future thinking must prevent wars...The stakes are immense, the task colossal the time is short. But we may hope- we must hope- that man's own creation, man's own genius, will not destroy him.
