If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success.

All attempts to adapt our ethical code to our situation in the technological age have failed.

Something which is against natural laws seems to me rather out of the question because it would be a depressive idea about God. It would make God smaller than he must be assumed. When he stated that these laws hold, then they hold, and he wouldn't make exceptions. This is too human an idea. Humans do such things, but not God.

Physics as we know it will be over in six months.

I am now convinced that theoretical physics is actually philosophy.

During my span of life science has become a matter of public concern and the l'art pour l'art standpoint of my youth is now obsolete. Science has become an integral and most important part of our civilization, and scientific work means contributing to its development. Science in our technical age has social, economic, and political functions, and however remote one's own work is from technical application it is a link in the chain of actions and decisions which determine the fate of the human race. I realized this aspect of science in its full impact only after Hiroshima.

But in practical affairs, particularly in politics, men are needed who combine human experience and interest in human relations with a knowledge of science and technology. Moreover, they must be men of action and not contemplation. I have the impression that no method of education can produce people with all the qualities required. I am haunted by the idea that this break in human civilization, caused by the discovery of the scientific method, may be irreparable.
