Paul Karl Feyerabend: Theory

“Experience 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 Karl Feyerabend book Against Method

“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.”

“Theories are abandoned and superseded by more fashionable accounts long before they have had an opportunity to show their virtues.”

Context: Progress was often achieved by a "criticism from the past"… After Aristotle and Ptolemy, the idea that the earth moves - that strange, ancient, and "entirely ridiculous", Pythagorean view was thrown on the rubbish heap of history, only to be revived by Copernicus and to be forged by him into a weapon for the defeat of its defeaters. The Hermetic writings played an important part in this revival, which is still not sufficiently understood, and they were studied with care by the great Newton himself. Such developments are not surprising. No idea is ever examined in all its ramifications and no view is ever given all the chances it deserves. Theories are abandoned and superseded by more fashionable accounts long before they have had an opportunity to show their virtues. Besides, ancient doctrines and "primitive" myths appear strange and nonsensical only because their scientific content is either not known, or is distorted by philologists or anthropologists unfamiliar with the simplest physical, medical or astronomical knowledge.

Fashion

“The Conceptual apparatus of the theory and the emotions connected with its application, having penetrated all means of communication, all actions, and indeed the whole life of the community, now guarantees the success of methods such as transcendental deduction, analysis of usage, phenomenological analysis - which are means for further solidifying the myth… At the same time it is evident that all contact with the world is lost and the stability achieved, the semblance of absolute truth is nothing but absolute conformism.”

Context: [continued conjecture on empiricism] At this point an "empirical" theory of the kind described becomes almost indistinguishable from a second-rate myth. In order to realize this, we need only consider a myth such as the myth of witchcraft and of demonic possession that was developed by the Roman Catholic theologians and that dominated 15th-, 16th- and 17th-century thought on the European continent. This myth is a complex explanatory system that contains numerous auxiliary hypotheses designed to cover special cases, so it easily achieves a high degree of confirmation on the basis of observation. It has been taught for a long time; its content is enforced by fear, prejudice, and ignorance, as well as by a jealous and cruel priesthood. Its ideas penetrate the most common idiom, infect all modes of thinking and many decisions which mean a great deal in human life. It provides models for the explanation of a conceivable event - Conceivable, that is, for those who have accepted it. This being the case, its key terms will be fixed in an unambiguous manner and the idea (which may have led to such a procedure in the first place) that they are copies of unchanging entities and that change of meaning, if it should happen, is due to human mistake - This idea will now be very plausible. Such plausibility reinforces all the manoeuvres which are used for the preservation of the myth (elimination of opponents included). The Conceptual apparatus of the theory and the emotions connected with its application, having penetrated all means of communication, all actions, and indeed the whole life of the community, now guarantees the success of methods such as transcendental deduction, analysis of usage, phenomenological analysis - which are means for further solidifying the myth... At the same time it is evident that all contact with the world is lost and the stability achieved, the semblance of absolute truth is nothing but absolute conformism. For how can we possibly test, or improve upon the truth of a theory if it is built in such a manner then any conceivable event can be described, and explained, in terms of its principles? The only way of investigating such all-embracing principles would be to compare them with a different set of equally all embracing principles- but this procedure has been excluded from the very beginning.

“Now - how can we possibly examine something we use all the time and presuppose in every statement? How can we criticize the terms in which we habitually express our observations? Let us see! The first step in our criticism of commonly-used concepts is to create a measure of criticism, something with which these concepts can be compared. Of course, we shall later want to know a little more about the measuring stick itself; for example, we shall want to know whether it is better than, or perhaps not as good as, the material examined. But in order for this examination to start there must be a measuring-stick in the first place. Therefore, the first step in our criticism of customary concepts and customary reactions is to step outside the circle and either to invent a new conceptual system, for example a new theory, that clashes with the most carefully established observational results and confounds with the most plausible theoretical principles, or to import such a system from outside science, from religion, from mythology, from the ideas of incompetents, or the ramblings of madmen. This step is, again, counter-inductive, Counter-induction is thus both a fact”

“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.”

“We have to realize that a unified theory of the physical world simply does not exist. We have theories that work in restricted regions, we have purely formal attempts to condense them into a single formula, we have lots of unfounded claims (such as the claim that all of chemistry can be reduced to physics), phenomena that do not fit into the accepted framework are suppressed; in physics, which many scientists regard as the one really basic science, we have now at least three different point of view (relativity, dealing with the very large, quantum theory for an intermediate domain and various particle models for the very small) without a promise of conceptual (and not only formal) unification; perceptions are outside of the material universe (the mind-body problem is still unsolved) - from the very beginning the salesman of a universal truth cheated people into admissions instead of clearly arguing for their philosophy. And let us not forget that it was they and not the representatives of the traditions they attacked who introduced argument as the one and only universal arbiter. They praised argument - they constantly violated its principles.”

“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.”

“A scientist, an artist, a citizen is not like a child who needs papa methodology and mama rationality to give him security and direction, he can take care of himself, for he is the inventor not only of laws, theories, pictures, plays, forms of music, ways of dealing with his fellow man, institutions, but also entire world view, he is the inventor of entire forms of like.”
