Contro il metodo
Variante: Galileo viola importanti norme del metodo scientifico che furono inventate da Aristotele, migliorate da Grossatesta (fra gli altri), canonizzate dai positivisti logici (come Carnap e Popper); Galileo ebbe successo perché non segui queste regole; i suoi contemporanei, con pochissime eccezioni, ignorarono difficoltà fondamentali che esistevano a quell'epoca; e la scienza moderna si sviluppò rapidamente, e nella direzione "giusta" (dal punto di vista degli attuali adepti della scienza), proprio perché trascurò tali difficoltà. L'ignoranza fu una benedizione. Inversamente, un'applicazione più rigorosa dei canoni del metodo scientifico, una ricerca più decisa dei fatti rilevanti, un atteggiamento più critico, lungi dall'accelerare questo sviluppo, avrebbero condotto a un punto morto.

Science in a Free Society (1978)
Contesto: A free society is a society in which all traditions have equal rights and equal access to the centers of power. A tradition receives these rights not because the importance the cash value, as it were) it has for outsiders but because it gives meaning to the lives of those who participate in it.
“We need a dream-world in order to discover the features of the real world we think we inhabit.”
Origine: Against Method: Outline of an Anarchistic Theory of Knowledge
Pg 48
Against Method (1975)
Contesto: 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 Theories are abandoned and superseded by more fashionable accounts long before they have had an opportunity to show their virtues.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.

Against Method (1975)
Contesto: [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.

Against Method (1975)
Contesto: Combining this observation with the insight that science has no special method, we arrive at the result that 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. The assertion, however, that there is no knowledge outside science - extra scientiam nulla salus - is nothing but another and most convenient fairy-tale. Primitive tribes has more detailed classifications of animals and plant than contemporary scientific zoology and botany, they know remedies whose effectiveness astounds physicians (while the pharmaceutical industry already smells here a new source of income), they have means of influencing their fellow men which science for a long time regarded as non-existent (voodoo), they solve difficult problems in ways which are still not quite understood (building of the pyramids; Polynesian travels), there existed a highly developed and internationally known astronomy in the old Stone Age, this astronomy was factually adequate as well as emotionally satisfying, it solved both physical and social problems (one cannot say the same about modern astronomy) and it was tested in very simple and ingenious ways (stone observatories in England and in the South Pacific; astronomical schools in Polynesia - for a more details treatment an references concerning all these assertions cf. my Einfuhrung in die Naturphilosophie). There was the domestication of animals, the invention of rotating agriculture, new types of plants were bred and kept pure by careful avoidance of cross fertilization, we have chemical inventions, we have a most amazing art that can compare with the best achievement of the present. True, there were no collective excursions to the moon, but single individuals, disregarding great dangers to their soul and their sanity, rose from sphere to sphere to sphere until they finally faced God himself in all His splendor while others changed into animals and back into humans again. At all times man approached his surroundings with wide open senses and a fertile intelligence, at all times he made incredible discoveries, at all times we can learn from his ideas.

Against Method (1975)
Contesto: Is it not a fact that a learned physician is better equipped to diagnose and to cure an illness than a layman or the medicine-man of a primitive society? Is it not a fact that epidemics and dangerous individual diseases have disappeared only with the beginning of modern medicine? Must we not admit that technology has made tremendous advances since the rise of modern science? And are not the moon-shots a most and undeniable proof of its excellence? These are some of the questions which are thrown at the impudent wretch who dares to criticize the special positions of the sciences. The questions reach their polemical aim only if one assumes that the results of science which no one will deny have arisen without any help from non-scientific elements, and that they cannot be improved by an admixture of such elements either. "Unscientific" procedures such as the herbal lore of witches and cunning men, the astronomy of mystics, the treatment of the ill in primitive societies are totally without merit. Science alone gives us a useful astronomy, an effective medicine, a trustworthy technology. One must also assume that science owes its success to the correct method and not merely to a lucky accident. It was not a fortunate cosmological guess that led to progress, but the correct and cosmologically neutral handling of data. These are the assumptions we must make to give the questions the polemical force they are supposed to have. Not a single one of them stands up to closer examination.
“Its "success" is entirely man-made.”
Pg. 43 & 44
Against Method (1975)
Contesto: [On Empiricism ] It is evident, on the basis of our considerations, that this appearance of success cannot in the least be regarded as a sign of truth and correspondence with nature. Quite the contrary, suspicion arises that the absence of major difficulties is a result of the decrease of empirical content brought about by the elimination of alternatives, and of facts that can be discovered with their help. In other words, the suspicion arises that this alleged success is due to the fact that the theory, when extended beyond its starting point, was turned into rigid ideology. Such Ideology is "successful" not because it agrees so well with the facts; it is successful because no facts have been specified that could constitute a test, and because some such facts have been removed. Its "success" is entirely man-made. It was decided to stick to some ideas, come what may, and the result was, quite naturally, the survival of these ideas. If now the initial decision is forgotten, or made only implicitly, for example, if it becomes common law in physics, then the survival itself will seem to constitute independent support., it will reinforce the decision, or turn it into an explicate one, and in this way close the circle. This is how empirical "evidence" may be created by a procedure which quotes as its justification the very same evidence it has Produced.

Conquest of Abundance (2001 [posthumous])
Contesto: Many "educated citizens" take it for granted that reality is what scientists say it is and that other opinions may be recorded, but need not be taken seriously. But science offers not one story, it offers many; the stories clash and their relation to a story-independent "reality" is as problematic as the relation of the Homeric epics to an alleged "Homeric world."

Against Method (1975)
Contesto: My intention is not to replace one set of general rules by another such set: my intention is, rather, to convince the reader that all methodologies, even the most obvious ones, have their limits. The best way to show this is to demonstrate the limits and even the irrationality of some rules which she, or he, is likely to regard as basic. In the case that induction (including induction by falsification) this means demonstrating how well the counterinductive procedure can be supported by argument.
“I say that Auschwitz is an extreme manifestation of an attitude that still thrives in our midst.”
pg 309
Farewell to Reason (1987)
Contesto: 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."

Against Method (1975)
Contesto: Naive falsificationism takes it for granted that the laws of nature are manifest an not hidden beneath disturbances of considerable magnitude. Empiricism takes it for granted that sense experience is a better mirror of the world than pure thought. Praise of argument takes it for granted that the artifices of Reason give better results than the unchecked play of our emotions. Such assumptions may be perfectly plausible and even true. Still, one should occasionally put them to a test. Putting them to a test means that we stop using the methodology associated with them, start doing science in a different way and see what happens.
