I know that philosophically a murderer is not responsible for his crime, but I prefer not to take tea with him.
-
The aim of education must be the training of independently acting and thinking individuals who, however, see in the service to the community their highest life problem.
-
While I am a convinced pacifist there are circumstances in which I believe the use of force is appropriate - namely, in the face of an enemy unconditionally bent on destroying me and my people.
-
When a man points a finger at someone else, he should remember that three of his fingers are pointing at himself.
-
A man's ethical behaviour should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.
-
I believe in standardizing automobiles. I do not believe in standardizing human beings. Standardization is a great peril which threatens American culture.
-
Matter is real to my senses, but they aren't trustworthy. If Galileo or Copernicus had accepted what they saw, they would never have discovered the movement of the earth and planets.
-
The more one chases the quanta, the better they hide themselves.
-
We must remember that we do not observe nature as it actually exists, but nature exposed to our methods of perception. The theories determine what we can or cannot observe...Reality is an illusion, albeit a persistent one.
-
I am a determinist. As such, I do not believe in free will. The Jews believe in free will. They believe that man shapes his own life. I reject that doctrine philosophically. In that respect I am not a Jew.
-
We Jews have been too adaptable. We have been too eager to sacrifice our idiosyncrasies for the sake of social conformity. … Even in modern civilization, the Jew is most happy if he remains a Jew.
-
Princeton is a wonderful little spot. A quaint and ceremonious village of puny demigods on stilts.
-
Nuclear power is one hell of a way to boil water.
-
In matters concerning truth and justice there can be no distinction between big problems and small; for the general principles which determine the conduct of men are indivisible. Whoever is careless with truth in small matters cannot be trusted in important affairs.
-
The contemplation of this world beckoned as a liberation. The road to this paradise was not as comfortable and alluring as the road to the religious paradise; but it has shown itself reliable, and I have never regretted having chosen it.
-
One has to realize that the powerful industrial groups concerned in the manufacture of arms are doing their best in all countries to prevent the peaceful settlement of international disputes, and that rulers can achieve this great end only if they are sure of the vigorous support of the majority of their peoples.
-
People like you and I, though mortal of course like everyone else, do not grow old no matter how long we live...We never cease to stand like curious children before the great mystery into which we were born.
-
I am a Jew, but I am enthralled by the luminous figure of the Nazarene….No one can read the Gospels without feeling the actual presence of Jesus.
-
Besides agreeing with the aims of vegetarianism for aesthetic and moral reasons, it is my view that a vegetarian manner of living by its purely physical effect on the human temperament would most beneficially influence the lot of mankind.
-
Fundamental ideas play the most essential role in forming a physical theory. Books on physics are full of complicated mathematical formulae. But thought and ideas, not formulae, are the beginning of every physical theory. The ideas must later take the mathematical form of a quantitative theory, to make possible the comparison with experiment.
-
I never failed in mathematics. Before I was fifteen I had mastered differential and integral calculus.
-
Not until we dare to regard ourselves as a nation, not until we respect ourselves, can we gain the esteem of others, or rather only then will it come of its own accord.
-
No man can visualize four dimensions, except mathematically … I think in four dimensions, but only abstractly. The human mind can picture these dimensions no more than it can envisage electricity. Nevertheless, they are no less real than electro-magnetism, the force which controls our universe, within, and by which we have our being.

Relativity applies to physics, not ethics.
