“In light of knowledge obtained, the happy achievement seems almost a matter of course, and any intelligent student can grasp it without too much trouble. But the years of anxious searching in the dark, with their intense longing, their alternations of confidence and exhaustion, and final emergence into light—only those who have experienced it can understand that.”

“By an application of the theory of relativity to the taste of readers, today in Germany I am called a German man of science, and in England I am represented as a Swiss Jew. If I come to be represented as a bête noire, the descriptions will be reversed, and I shall become a Swiss Jew for the Germans and a German man of science for the English!”

Noch eine Art Anwendung des Relativitätsprinzips zum Ergötzen des Lesers: Heute werde ich in Deutschland als "deutscher Gelehrter", in England als "Schweizer Jude" bezeichnet; sollte ich aber einst in die Lage kommen, als "bète noire" präsentiert zu werden, dann wäre ich umgekehrt für die Deutschen ein „Schweizer Jude“, für die Engländer ein "deutscher Gelehrter".

Variant translation: If my theory of relativity is proven correct, Germany will claim me as a German and France will say I am a man of the world. If it's proven wrong, France will say I am a German and Germany will say I am a Jew. 1910s Variant: If my theory of relativity is proven successful, 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.

If relativity is proved wrong the French will call me a Swiss, the Swiss will call me a German and the Germans will call me a Jew.
