—Emma Goldman (1869–1940)
“If my theory of relativity is proven correct, Germany will claim me as a German and France will declare that I am a citizen of the world. Should my theory prove untrue, France will say that I am a German and Germany will declare that I am a Jew.”
—Albert Einstein (1879–1955)
“Frankly, these days, without a theory to go with it, I can’t see a painting.”
