When you are courting a nice girl an hour seems like a second. When you sit on a red-hot cinder a second seems like an hour. That's relativity.

Make everything as simple as possible, but not simpler.

Our schoolbooks glorify war and conceal its horrors. They indoctrinate children with hatred. I would teach peace rather than war, love rather than hate.

The cult of individual personalities is always, in my view, unjustified. To be sure, nature distributes her gifts variously among her children. But there are plenty of the well-endowed ones too, thank God, and I am firmly convinced that most of them live quiet, unregarded lives.

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

When a man, after long years of searching, chances upon a thought which discloses something of the beauty of this mysterious universe, he should not therefore be personally celebrated. He is already sufficiently paid by his experience of seeking and finding.

Anti-Semitism is nothing but the antagonistic attitude produced in the non-Jew by the Jewish group. This is a normal social reaction. The Jewish group has thrived on oppression and on the antagonism it has forever met in the world... the root cause is their use of enemies they create in order to keep solidarity.
