I am by heritage a Jew, by citizenship a Swiss, and by makeup a human being, and only a human being, without any special attachment to any state or national entity whatsoever.

I advocate world government because I am convinced that there is no other possible way of eliminating the most terrible danger in which man has ever found himself. The objective of avoiding total destruction must have priority over any other objective.

A conviction akin to religious feeling of the rationality or intelligibility of the world lies behind all scientific work of a high order.

Classical thermodynamics ... is the only physical theory of universal content which I am convinced ... will never be overthrown.

The flag is a symbol of the fact that man is still a herd animal.

Enjoying the joys of others and suffering with them-these are the best guides for man.

Without "ethical culture", there is no salvation for humanity.
