"The material which a scientist actually has at his disposal, his laws, his experimental results, his mathematical techniques, his epistemological prejudices, his attitude towards the absurd consequences of the theories which he accepts, is indeterminate in many ways, ambiguous, and never fully separated from the historical background. This material is always contaminated by principles which he does not know and which, if known, would be extremely hard to test."

“And where is the boundary-if there is a boundary-between a collective outlook and "the world"?. Many cultures assume such a boundary, but they set it in different places. Divine appearances once were real- they are mere fantasies today. Where shall we, who examine the phenomenon, set the boundary?”

“No single theory ever agrees with all the facts in its domain”

“There is no "scientific worldview" just as there is no uniform enterprise "science"- except in the minds of metaphysicians, school masters, and scientists blinded by the achievements of their own particular niche... There is no objective principle that could direct us away from the supermarket "religion" or the supermarket "art" toward the more modern, and much more expensive supermarket "science." Besides, the search for such guidance would be in conflict with the idea of individual responsibility which allegedly is an important ingredient of a "rational" or scientific age.”

“Science is not sacrosanct. The mere fact that it exists, is admired, has results is not sufficient for making it a measure of excellence. Modern science arose from global objections against earlier views and rationalism itself, the idea that there are general rules and standards for conducting our affairs, affairs of knowledge included, arose from global objections to common sense.”

“I say that Auschwitz is an extreme manifestation of an attitude that still thrives in our midst. It shows itself in the treatment of minorities in industrial democracies; in education, education to a humanitarian point of view included, which most of the time consists of turning wonderful young people into colorless and self-righteous copies of their teachers; it becomes manifest in the nuclear threat, the constant increase in the number and power of deadly weapons and the readiness of some so-called patriots to start a war compared with which the holocaust will shrink into insignificance. It shows itself in the killing of nature and of "primitive" cultures with never a thought spent on those thus deprived of meaning for their lives; in the colossal conceit of our intellectuals, their belief that they know precisely what humanity needs and their relentless efforts to recreate people in their sorry image; in the infantile megalomania of some of our physicians who blackmail their patients with fear, mutilate them and then persecute them with large bills; in the lack of feeling of so many so-called searchers for truth who systematically torture animals, study their discomfort and receive prizes for their cruelty. As far as I am concerned there exists no difference between the henchmen of Aushwitz and these "benefactors of mankind.”

“Most scientists today are devoid of ideas, full of fear, intent on producing some paltry result so that they can add to the flood of inane papers that now constitutes "scientific progress" in many areas.”
