Time and space are modes by which we think and not conditions in which we live.

I find it difficult to believe that I belong to such an idiotic, rotten species - the species that actually boasts of its freedom of will, heroism on command, senseless violence, and all of the loathsome nonsense that goes by the name of patriotism.

The Nuremberg Trial of the German war criminals was tacitly based on the recognition of the principle: criminal actions cannot be excused if committed on government orders; conscience supersedes the authority of the law of the state.

May the conscience and the common sense of the peoples be awakened, so that we may reach a new stage in the life of nations, where people will look back on war as an incomprehensible aberration of their forefathers!

It is easy to say something new, if all senses one will eschew. But hardly ever is found, that the new is also sound.

Thus I came...to a deep religiosity, which, however, reached an abrupt end at the age of 12. Through the reading of popular scientific books I soon reached a conviction that much in the stories of the Bible could not be true....Suspicion against every kind of authority grew out of this experience...an attitude which has never left me.

It is impossible to solve significant problems using the same knowledge that created them.
