Paul Karl Feyerabend

"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."

"There is no coherent knowledge, i.e. no uniform comprehensive account of the world and the events in it. There is no comprehensive truth that goes beyond an enumeration of details, but there are many pieces of information, obtained in different ways from different sources and collected for the benefit of the curious. The best way of presenting such knowledge is the list - and the oldest scientific works were indeed lists of facts, parts, coincidences, problems in several specialized domains."

"The sciences of today are business enterprises run on business principles. Research in large institutes is not guided by Truth and Reason but by the most rewarding fashion, and the great minds of today increasingly turn to where the money is - which means military matters."

"All religion may be centered around a generally good idea, however, this has not stopped its adherents from acting like bastards"

"If the world is an aggregate of relatively independent regions, then any assumption of universal laws is false and a demand for universal norms tyrannical: only brute force (or seductive deception) can then bend the different moralities so that they fit the prescriptions of a single ethical system. And indeed, the idea of universal laws of nature and society arose in connection with a life-and-death battle: the battle that gave Zeus the power over the Titans and all other gods and thus turned his laws into the laws of the universe."

"'Truth', written 'in capital letters', is an orphan in this world, without power and influence... ['Reason'] cannot stand diverging opinions - it calls them 'lies'; it puts itself 'above' the real lives of human beings, demanding, in a way characteristic of all totalitarian ideologies, the right to rebuild the world from the height of 'what it should be', i.e. in accordance with its own 'invincible' precepts. It refuses to recognize the many ideas, actions, feelings, laws, institutions, racial features which separate one nation (culture, civilization) from another... The reason of ordinary people trying to create a better and safer world for themselves and their children (which is reason with a small 'r' and not Reason 'written in capital letters') has very little in common with these ignorant dreams of domination."

"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.""

"People have different professions, different points of view. They are like observers looking at the world through the narrow windows of an otherwise closed structure. Occasionally they assemble at the center and discuss what they have seen; then one observer will talk about a beautiful landscape with red trees, a red sky, and a red lake in the middle; the next one about an infinite blue plane without articulation; and the third about an impressive, five-floor-high building; they will quarrel. The observer on top of the structure (me) can only laugh at their quarrels-but for them the quarrels will be real and he (the observer on top) will be an unworldly dreamer. Real life... is exactly like that. Every person has his own well-defined opinions, which color the section of the world he perceives. And when people come together, when they try to discover the nature of the whole which they belong, they are bound to talk past each other; they will understand neither themselves nor their companions."

"Somewhere among the commotion I grew rather depressed. The depression stayed with me for over a year; it was like an animal, a well-defined, spatially localizable thing. I would wake up, open my eyes, listen-is it here or isn’t it? No sign of it. Perhaps it’s asleep. Perhaps it will leave me alone today. Carefully, very carefully, I get out of bed. All is quiet. I go to the kitchen, start breakfast. Not a sound. TV-Good Morning America, David what’s-his-name, a guy I can’t stand. I eat and watch the guests. Slowly the food fills my stomach and gives me strength. Now a quick excursion to the bathroom, and out for my morning walk-and here she is, my faithful depression: “Did you think you could leave without me?" I had often warned my students not to identify with their work. I told them, “if you want to achieve something, if you want to write a book, paint a picture, be sure that the center of your existence if somewhere else and that it’s solidly grounded; only then will you be able to keep your cool and laugh at the attacks that are bound to come." I myself had followed this advice in the past, but now I was alone, sick with some unknown affliction; my private life was in a mess, and I was without a defense. I often wished I had never written that fucking book."

"Those who violate the rules of a language do not enter new territory; they leave the domain of meaningful discourse. Even facts in these circumstances dissolve, because they are shaped by the language and subjected to its limitations."

"And where is the boundary-if there is a boundary-between a collective outlook and "the world"?. Many cultures assume such a boundary, but they set it in different places. Divine appearances once were real- they are mere fantasies today. Where shall we, who examine the phenomenon, set the boundary?"

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

"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.""

"Human paint, produce films and videos; they dance, dream and make music; they engage in political action, exchange goods, perform rituals, build houses start wars, act in plays, try to please patrons- and so on... They contain patterns, press the practitioners to "conform" and in this way mold their thought, their perception, their actions, and their discriminative abilities."

"The existence of antagonistic "conspiracies" was recognized by the defenders of religious and political views. Iconoclasts knew that images might distort the basic message of their creed (which consisted of words and resided in Holy Books). Church architecture and church music were adapted to the needs of the Holy Faith. Alternative styles were either fought or made part of religious PR. I conclude that our 'field of experience' is molded, overlaid, and 'conspired' against not just by language, but by numerous other patterns and institutions, many of them in mutual conflict. An inference from a style, a particular linguistic apparatus, or, more recently, from scientific beliefs, to a cosmology, corresponding ways of life and an all-embracing "spirit of the age therefore needs special support; it cannot be made as a matter of course."

"Ultimate Reality, if such an entity can be postulated, is ineffable."

"What is surprising is that almost all the trends that developed within the sciences, Aristotelianism and an extreme Platonism included, produced results, not only in special domains, but everywhere; there exist highly theoretical branches of biology and highly empirical parts of astrophysics. The world is a complex an many-sided thing."

"There is no "scientific worldview" just as there is no uniform enterprise "science"- except in the minds of metaphysicians, school masters, and scientists blinded by the achievements of their own particular niche... There is no objective principle that could direct us away from the supermarket "religion" or the supermarket "art" toward the more modern, and much more expensive supermarket "science." Besides, the search for such guidance would be in conflict with the idea of individual responsibility which allegedly is an important ingredient of a "rational" or scientific age."

"Early Chinese thinkers had taken variety at face value. They had favored diversification and collected anomalies instead of trying to explain them away."

"So far Unitarian realism claiming to possess positive knowledge about Ultimate Reality has succeeded only by excluding large areas of phenomena or by declaring, without proof, that they could be reduced to basic theory, which, in this connection, means elementary particle physics."

"The members of the Japanese enlightenment of the early 1870's, Fukuzawa among them, now reasoned as follows: Japan can keep its independence only if it becomes stronger. It can become stronger only with the help of science. It will use science effectively only if it does not just practice science but also believes in the underlying ideology. To many traditional Japanese this ideology-the scientific worldview- was barbaric. But, so the followers of Fukuzawa argued, it was necessary to adopt barbaric ways, to regard them as advanced, to introduce the whole of Western civilization in order to survive. Having been thus prepared, Japanese scientists soon branched out as their Western colleagues had done before and falsified the uniform ideology that had started the development. The lesson I draw from this sequence of events is that a uniform 'scientific view of the world' may be useful for people doing science... However, it is a disaster for outsiders(philosophers, fly-by-night mystics, prophets of a new age, the (educated public"), who, being undisturbed by the complexities of research, are liable to fall for the most simpleminded and most vapid tale."

"Humane science must be adapted to the requirements of a balanced and rewarding life."

"A Universal Good should reflect the reality of the individual benefits that are collected under its name, not the other way around."

"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."

"First-world science is one science among many; by claiming to be more it ceases to be an instrument of research and turns into a (political) pressure group."

"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."

"Without a constant misuse of language, there cannot be any discovery, any progress."

"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."

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

"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."

"[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."

"My life has been the result of accidents, not of goals and principles. My intellectual work forms only an insignificant part of it. Love and personal understanding are much more important. Leading intellectuals with their zeal for objectivity kill these personal elements. They are criminals, not the leaders of mankind."
