“Everything must be taken into account. If the fact will not fit the theory — let the theory go.”

“Philosophy is, in the last instance, class struggle in the field of theory.”

Die Quantentheorie ist so ein wunderbares Beispiel dafür, daß man einen Sachverhalt in völliger Klarheit verstanden haben kann und gleichzeitig doch weiß, daß man nur in Bildern und Gleichnissen von ihm reden kann.
Der Teil und das Ganze. Gespräche im Umkreis der Atomphysik (1969); also in "Kein Chaos, aus dem nicht wieder Ordnung würde", Die Zeit No. 34 (22 August 1969) http://www.zeit.de/1969/34/kein-chaos-aus-dem-nicht-wieder-ordnung-wuerde/komplettansicht; as translated in Physics and Beyond : Encounters and Conversation (1971)
“In theory there is no difference between theory and practice; in practice there is.”
Attributed in Nassim Nicholas Taleb, Antifragile - Things that Gain From Disorder (2012), p. 213.
The earliest known appearance of this quote in print is Walter J. Savitch, Pascal: An Introduction to the Art and Science of Programming (1984), where it is attributed as a "remark overheard at a computer science conference". It circulated as an anonymous saying for more than ten years before attributions to Jan L. A. van de Snepscheut and Yogi Berra began to appear (and later still to various others).
Disputed, Misattributed

Autobiographical Notes (1952)
Context: I don't like people who like me because I'm a Negro; neither do I like people who find in the same accident grounds for contempt. I love America more than any other country in the world, and, exactly for this reason, I insist on the right to criticize her perpetually. I think all theories are suspect, that the finest principles may have to be modified, or may even be pulverized by the demands of life, and that one must find, therefore, one's own moral center and move through the world hoping that this center will guide one aright. I consider that I have many responsibilities, but none greater than this: to last, as Hemingway says, and get my work done.
I want to be an honest man and a good writer.
“I pass with relief from the tossing sea of Cause and Theory to the firm ground of Result and Fact.”

Context: Here’s my theory about meetings and life: the three things you can’t fake are erections, competence and creativity. That’s why meetings become toxic — they put uncreative people in a situation in which they have to be something they can never be. And the more effort they put into concealing their inabilities, the more toxic the meeting becomes.
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. (Address to the French Philosophical Society at the Sorbonne (6 April 1922); French press clipping (7 April 1922) [Einstein Archive 36-378] and Berliner Tageblatt (8 April 1922) [Einstein Archive 79-535])
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.
Variant: If relativity is proved right the Germans will call me a German, the Swiss will call me a Swiss citizen, and the French will call me a great scientist. 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.
Context: 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!
“I have this theory: If you forgive someone, they can't hurt you anymore.”
Variant: If we assume that man actually does resemble God, then we are forced into the impossible theory that God is a coward, an idiot and a bounder.
Texts and Pretexts (1932), p. 270
Context: It is man's intelligence that makes him so often behave more stupidly than the beasts. … Man is impelled to invent theories to account for what happens in the world. Unfortunately, he is not quite intelligent enough, in most cases, to find correct explanations. So that when he acts on his theories, he behaves very often like a lunatic. Thus, no animal is clever enough, when there is a drought, to imagine that the rain is being withheld by evil spirits, or as punishment for its transgressions. Therefore you never see animals going through the absurd and often horrible fooleries of magic and religion. No horse, for example would kill one of its foals to make the wind change direction. Dogs do not ritually urinate in the hope of persuading heaven to do the same and send down rain. Asses do not bray a liturgy to cloudless skies. Nor do cats attempt, by abstinence from cat's meat, to wheedle the feline spirits into benevolence. Only man behaves with such gratuitous folly. It is the price he has to pay for being intelligent but not, as yet, intelligent enough.
