Knowledge is not a series of self-consistent theories that converges toward an ideal view; it is rather an ever increasing ocean of mutually incompatible (and perhaps even incommensurable) alternatives, each single theory, each fairy tale, each myth that is part of the collection forcing the others into greater articulation and all of them contributing, via this process of competition, to the development of our consciousness.
Paul FeyerabendIt is clear, then, that the idea of a fixed method, or of a fixed theory of 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 FeyerabendAll religion may be centered around a generally good idea, however, this has not stopped its adherents from acting like bastards.
Paul FeyerabendExperience arises together with theoretical assumptions not before them, and an experience without theory is just as incomprehensible as is (allegedly) a theory without experience.
Paul FeyerabendTaking 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 FeyerabendNo 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.
