The only principle that does not inhibit progress is: anything goes.

Paul Feyerabend
The ideas survived and they can now be said to be in agreement with reason. They survived because prejudice, passion, conceit, errors, sheer pigheadedness, in short because all the elements that characterize the context of discovery, opposed the dictates of reason and because these irrational elements were permitted to have their way. To express it differently: Copernicanism and other "rational" views exist today only because reason was overruled at some time in their past. (The opposite is also true: witchcraft and other "irrational" views had ceased to be influential only because reason was overruled at some time in their past.)

Paul Feyerabend
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.

Paul Feyerabend
The idea that science can, and should, be run according to fixed and universal rules, is both unrealistic and pernicious.

Paul Feyerabend
The history of science will be as complex, chaotic, full of mistakes, and entertaining as the ideas it contains, and these ideas in turn will be as complex, chaotic, full of mistakes, and entertaining as are the minds of those who invented them.

Paul Feyerabend
There is no idea, however ancient and absurd, that is not capable of improving our knowledge.

Paul Feyerabend
Copemicanism and other essential ingredients of modem science survived only because reason was frequently overruled in their past.

Paul Feyerabend
There is not a single rule, however plausible, and however firmly grounded in epistemology, that is not violated at some time or other. It becomes evident that such violations are not accidental events, they are not results of insufficient knowledge or of inattention which might have been avoided. On the contrary, we see that they are necessary for progress.

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

Paul Feyerabend
Everywhere science is enriched by unscientific methods and unscientific results,... the separation of science and non-science is not only artificial but also detrimental to the advancement of knowledge. If we want to understand nature, if we want to master our physical surroundings, then we must use all ideas, all methods, and not just a small selection of them.

Paul Feyerabend
Not only are facts and theories in constant disharmony, they are never as neatly separated as everyone makes them out to be.

Paul Feyerabend
Teachers' using grades and the fear of failure mould the brains of the young until they have lost every ounce of imagination they might once have possessed.

Paul Feyerabend
[Responding to criticism from Dr. Hesse] Voodoo, Dr Hesse's piece de risistance', is case in point. Nobody knows it, everybody uses it as a paradigm of backwardness and confusion. And yet Voodoo has a firm though still not sufficiently understood material basis, and a study of its manifestations can be used to enrich, and perhaps even revise, our knowledge of physiology.

Paul Feyerabend
No theory ever agrees with all the facts in its domain, yet it is not always the theory that is to blame. Facts are constituted by older ideologies, and a clash between facts and theories may be proof of progress. It is also a first step in our attempt to find the principles implicit in familiar observational notions.

Paul Feyerabend
It is clear, then, that the idea of a fixed method, or of a fixed theory or rationality, rests on too naive a view of man and his social surroundings. To those who look at the rich material provided by history, and who are not intent on impoverishing it in order to please their lower instincts, their craving for intellectual security in the form of clarity, precision, "objectivity", "truth", it will become clear that there is only one principle that can be defended under all circumstances and in all stages of human development. It is the principle: anything goes.

Paul Feyerabend
The separation of state and church must be complemented by the separation of state and science, that most recent, most aggressive, and most dogmatic religious institution.

Paul Feyerabend
An anarchist is like an undercover agent who plays the game of Reason in order to undercut the authority of Reason (Truth, Honesty, Justice and so on).

Paul Feyerabend
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.

Paul Feyerabend
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.

Paul Feyerabend
Taking experimental results and observations for granted and putting the burden of proof on the theory means taking the observational ideology for granted without having ever examined it.

Paul Feyerabend
I had studied Dadaism after the Second World War. What attracted me to this movement was the style its inventors used when not engaged in Dadaistic activities. It was clear, luminous, simple without being banal, precise without being narrow; it was a style adapted to the expression of thought as well as of emotion. I connected this style with the Dadaistic exercises themselves

Paul Feyerabend
Unanimity of opinion may be fitting for a church, for the frightened or greedy victims of some (ancient, or modern) myth, or for the weak and willing followers of some tyrant. Variety of opinion is necessary for objective knowledge. And a method that encourages variety is also the only method that is comparable with a humanitarian outlook.

Paul Feyerabend
Science is an essentially anarchic enterprise: theoretical anarchism is more humanitarian and more likely to encourage progress than its law-and-order alternatives.

Paul Feyerabend
One can show the following: given any rule, however "fundamental" or "necessary" for science, there are always circumstances when it is advisable not only to ignore the rule, but to adopt its opposite.

Paul Feyerabend
The time is overdue for adding the separation of state and science to the by now customary separation of state and church. Science is only one of the many instruments man has invented to cope with his surroundings. It is not the only one, it is not infallible, and it has become too powerful, too pushy, and too dangerous to be left on its own.
