I am neither a German citizen, nor do I believe in anything that can be described as a 'Jewish faith.' But I am a Jew and glad to belong to the Jewish people, though I do not regard it in any way as chosen.
-
The development during the present century is characterized by two theoretical systems essentially independent of each other: the theory of relativity and the quantum theory. The two systems do not directly contradict each other; but they seem little adapted to fusion into one unified theory.
-
In the teaching of geography and history a sympathetic understanding be fostered for the characteristics of the different peoples of the world, especially for those who we are in the habit of describing as primitive.
-
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.
-
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.

Only a very dull man spells a word the same way twice.
-
If I would be a young man again and had to decide how to make my living, I would not try to become a scientist or scholar or teacher. I would rather choose to be a plumber or a peddler in the hope to find that modest degree of independence still available under present circumstances.
-
The physicists say that I am a mathematician, and the mathematicians say that I am a physicist. I am a completely isolated man and though everybody knows me, there are very few people who really know me.
-
Some men spend a lifetime in an attempt to comprehend the complexities of women. Others pre-occupy themselves with somewhat simpler tasks, such as understanding the theory of relativity!
-
Lasting harmony with a woman was an undertaking in which I twice failed rather disgracefully.
-
The unleashed power of the atom has changed everything save our modes of thinking and we thus drift toward unparalleled catastrophe.
-
I never failed in mathematics. Before I was fifteen I had mastered differential and integral calculus.
-
Freud's sense of reality is less clouded by wishful thinking than is the case with other people and he combines the qualities of critical judgment, earnestness and responsibility.
-
We can invent as many theories we like, and any one of them can be made to fit the facts. But that theory is always preferred which makes the fewest number of assumptions.
-
It gives me great pleasure, indeed, to see the stubbornness of an incorrigible nonconformist warmly acclaimed.
-
Nuclear power is one hell of a way to boil water.
-
War seems to me to be a mean, contemptible thing: I would rather be hacked in pieces than take part in such an abominable business. And yet so high, in spite of everything, is my opinion of the human race that I believe this bogey would have disappeared long ago, had the sound sense of the nations not been systematically corrupted by commercial and political interests acting through the schools and the Press.
-
My scientific work is motivated by an irresistible longing to understand the secrets of nature and by no other feeling. My love for justice and striving to contribute towards the improvement of human conditions are quite independent from my scientific interests.
-
At the same time, as social beings, we are moved in the relations with our fellow beings by such feelings as sympathy, pride, hate, need for power, pity, and so on.
-
The bigotry of the nonbeliever is for me nearly as funny as the bigotry of the believer.
-
Belief in an external world independent of the perceiving subject is the basis of all natural science.

There is, fortunately, a minority composed of those who recognize early in their lives that the most beautiful and satisfying experiences open to humankind are not derived from the outside, but are bound up with the development of the individual's own feeling, thinking and acting. The genuine artists, investigators and thinkers have always been persons of this kind. However inconspicuously the life of these individuals runs its course, none the less the fruits of their endeavors are the most valuable contributions which one generation can make to its successors.
