The beauty of it is that we have to content ourselves with the recognition of the miracle, beyond which there is no legitimate way out.

No, this trick won't work... How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love?

I was just more stubborn and more passionate than most about physics.

If you cannot explain it simply, you do not understand it enough.

With all my heart I believe that the world's present system of sovereign nations can only lead to barbarism, war and inhumanity, and that only world law can assure progress towards a civilized peaceful community.

I cannot imagine a God who rewards and punishes the objects of his creation and is but a reflection of human frailty.

In two weeks the sheeplike masses of any country can be worked up by the newspapers into such a state of excited fury that men are prepared to put on uniforms and kill and be killed, for the sake of the sordid ends of a few interested parties. Compulsory military service seems to me the most disgraceful symptom of that deficiency in personal dignity from which civilized mankind is suffering today.
