“Experts often arrive at different results, both in fundamental matters, and in application Who does not know of at least one case in his family where one doctor recommends a certain operation, another argues against it, while a third suggests an entirely different procedure? Who has not read of the debates about nuclear safety, the of the economy, the effects of pesticides, aerosol sprays, the efficiency of methods of education, the influence of race on intelligence? Two, three, five and even more views arise in such debates, and scientific supporters can be found for all of them. Occasionally one almost feels inclined to say: as many scientists, as many opinions. There are of course areas in which scientists agree- but this cannot raise our confidence. Unanimity is often the result of a political decision: dissenters are suppressed, or remain silent to preserve the reputation of science as a source of trustworthy and almost infallible knowledge. On other occasions, unanimity is the result of shared prejudices: positions are taken without detail examination of the matter under review and are infused with the same authority that proceeds from detailed research.”

Encountering Directors interview (1969)
Context: When a scene is being shot, it is very difficult to know what one wants it to say, and even if one does know, there is always a difference between what one has in mind and the result on film. I never think ahead of the shot I'm going to make the following day because if I did, I'd only produce a bad imitation of the original image in my mind. So what you see on the screen doesn't represent my exact meaning, but only my possibilities of expression, with all the limitations implied in that phrase. Perhaps the scene reveals my incapacity to do better; perhaps I felt subconsciously ironic toward it. But it is on film; the rest is up to you.

Nobel Prize autobiography (1998)
Context: The world is full of intelligent, well-meaning people who, for one reason or another, did not attend university but are nonetheless well-read and educated. Out there on the prairie lost opportunities of youth were the rule rather than the exception, and I slowly became disabused of the myth of the Bright Young Thing and have not believed in it since.
