The idea of a method that contains firm, unchanging, and absolutely binding principles for conducting the business of science meets considerable difficulty when confronted with the results of historical research. We find, then, that there is not a single rule, however plausible, and however firmly grounded in epistemology, that is not violated at some time or another.

Science is neither a single tradition, nor the best tradition there is, except for people who have become accustomed to its presence, its benefits and its disadvantages. In a democracy it should be separated from the state just as churches are now separated from the state.

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.

One knows quite well that harmony can be a harmony of appearances.

Arguments hardly affect the faithful- their beliefs have an entirely different foundation.

Rationalism... is a secularized form of the belief in the power of the word of God.

Language became a colorless and as indistinct as the business suit which is now worm by everyone, by the scholar, by the businessman, by the professional killer. Being accustomed to a dry and dreary norm and sees in it an obvious sign of arrogance and aggression; viewing authority with almost religious awe he gets into a frenzy when he sees someone pluck the beard of his favorite prophet.
