The more I learn of physics, the more I am drawn to metaphysics.

The most important human endeavor is the striving for morality in our actions. Our inner balance and even our very existence depend on it. Only morality in our actions can give beauty and dignity to life.

Capitalism creates a huge community of producers who are unceasingly striving to deprive each other of the fruits of their collective labor, and an oligarchy that cannot be effectively checked even by a democratically organized society....the subjugation is not by force but because the privileged class has long ago established a system of values by which the people were thenceforth, to a large extent unconsciously, guided in their social behavior.

Thus I came...to a deep religiosity, which, however, reached an abrupt end at the age of 12.

For me the Jewish religion like all others is an incarnation of the most childish superstitions, and the Jewish people to whom I gladly belong and with whose mentality I have a deep affinity have no different quality for me than all other people. As far as my experience goes, they are no better than other human groups, although they are protected from the worst cancers by a lack of power. Otherwise I cannot see anything chosen about them.
