Theory Quotes

“Throughout his last half-dozen books, for example, Arthur Koestler has been conducting a campaign against his own misunderstanding of Darwinism. He hopes to find some ordering force, constraining evolution to certain directions and overriding the influence of natural selection. [...] Darwinism is not the theory of capricious change that Koestler imagines. Random variation may be the raw material of change, but natural selection builds good design by rejecting most variants while accepting and accumulating the few that improve adaptation to local environments.”

“A religious creed differs from a scientific theory in claiming to embody eternal and absolutely certain truth, whereas science is always tentative, expecting that modification in its present theories will sooner or later be found necessary, and aware that its method is one which is logically incapable of arriving at a complete and final demonstration.”

“In a Society in which there is no law, and in theory no compulsion, the only arbiter of behaviour is public opinion. But public opinion, because of the tremendous urge to conformity in gregarious animals, is less tolerant than any system of law. When human beings are governed by "thou shalt not", the individual can practise a certain amount of eccentricity: when they are supposedly governed by "love" or "reason", he is under continuous pressure to make him behave and think in exactly the same way as everyone else.”

“There is little mysticism without an element of transcendence, and conversely, there is no transcendence without a certain degree of egocentrism. It may be that the genesis of these experiences is to be sought in the unique situation of the very young child in relation to adults. The theory of the filial origin of the religious sense seems to us singularly convincing in this connection.”

“I can have little patience with those who oppose ... the theory of evolution or what are called "mechanistic" explanations of the phenomena of life because of certain moral consequences which at first seem to follow from these theories, and still less with those who regard it as irrelevant or impious to ask certain questions at all. By refusing to face the facts , the conservative only weakens his own position.”

“In thermodynamics as well as in other branches of molecular physics , the laws of phenomena have to a certain extent been anticipated, and their investigation facilitated, by the aid of hypotheses as to occult molecular structures and motions with which such phenomena are assumed to be connected. The hypothesis which has answered that purpose in the case of thermodynamics, is called that of "molecular vortices," or otherwise, the "centrifugal theory of elasticity.”

“Monopolies are not justified by theory; they should be permitted only when justified by facts. If there is no solid basis for extending a certain monopoly protection, then we should not extend that protection. This does not mean that every copyright must prove its value initially. That would be a far too cumbersome system of control. But it does mean that every system or category of copyright or patent should prove its worth. Before the monopoly should be permitted, there must be reason to believe it will do some good -- for society, and not just for monopoly holders.”

“History has got a lot to do with unique circumstances under certain particular cases and grand theories will always find counter cases. I don't think that people whose expertise lies in one thing should try to make grand theories about something (a) where it's very hard to get the evidence to prove that you're right and (b) where it's much too easy to make up stories that seem right.”

“Those who are in love with practice without knowledge are like the sailor who gets into a ship without rudder or compass and who never can be certain whether he is going. Practice must always be founded on sound theory, and to this Perspective is the guide and the gateway; and without this nothing can be done well in the matter of drawing.”

“A taxonomy of abilities, like a taxonomy anywhere else in science, is apt to strike a certain type of impatient student as a gratuitous orgy of pedantry. Doubtless, compulsions to intellectual tidiness express themselves prematurely at times, and excessively at others, but a good descriptive taxonomy, as Darwin found in developing his theory, and as Newton found in the work of Kepler, is the mother of laws and theories.”

“Journalism only tells us what men are doing; it is fiction that tells us what they are thinking, and still more what they are feeling. If a new scientific theory finds the soul of a man in his dreams, at least it ought not to leave out his day-dreams. And all fiction is only a diary of day-dreams instead of days. And this profound preoccupation of men's minds with certain things always eventually has an effect even on the external expression of the age.”

“In geometry I find certain imperfections which I hold to be the reason why this science, apart from transition into analytics, can as yet make no advance from that state in which it came to us from Euclid. As belonging to these imperfections, I consider the obscurity in the fundamental concepts of the geometrical magnitudes and in the manner and method of representing the measuring of these magnitudes, and finally the momentous gap in the theory of parallels, to fill which all efforts of mathematicians have so far been in vain.”

“July 4, 1776 was the historic day on which the representatives of three millions of people vocalized Concord, and Lexington, and Bunker Hill, which gave notice to the world that they proposed to establish an independent nation on the theory that all men are created equal, that they are endowed by their creator with certain inalienable rights, that among these are life, liberty, and the pursuit of happiness.”

“Critical Race Theory offers a critique of how law and certain law reform strategies misunderstand the actual operation of life-shortening state violence, and how that has produced a set of reforms that fail to actually transform material conditions of white supremacy. These critiques redirect our attention to the conditions we aim to transform.”

“I am often talking about the ideas collected in Normal Life in contexts that are not academic, or that are full of people who are not primarily engaging as theorists or theory-readers. Being able to make ideas visual, especially critical ideas about movements that can be difficult to hear because of attachments we have to certain national narratives, or because of ways that we see ourselves, is especially useful.”

“For the law, the clarity of language and the finality of judgment is crucial, because you have to decide a case one way or another - whether it is criminal or civil or whatever. In ordinary life, you do not have to decide things with absolute finality. You do not have to decide on a theory in order to behave in a certain way towards other people.”

“I do not deny that medicine is a gift of God, nor do I refuse to acknowledge science in the skill of many physicians; but, take the best of them, how far are they from perfection? A sound regimen produces excellent effects. When I feel indisposed, by observing a strict diet and going to bed early, I generally manage to get round again, that is, if I can keep my mind tolerably at rest. I have no objection to the doctors acting upon certain theories, but, at the same time, they must not expect us to be the slaves of their fancies.”

“Yet the widespread planetary theories, advanced by Ptolemy and most other astronomers, although consistent with the numerical data, seemed likewise to present no small difficulty. For these theories were not adequate unless they also conceived certain equalizing circles, which made the planet appear to move at all times with uniform velocity neither on its deferent sphere nor about its own epicycle's center.”

“In terms of the game theory, we might say the universe is so constituted as to maximize play. The best games are not those in which all goes smoothly and steadily toward a certain conclusion, but those in which the outcome is always in doubt. Similarly, the geometry of life is designed to keep us at the point of maximum tension between certainty and uncertainty, order and chaos. Every important call is a close one. We survive and evolve by the skin of our teeth. We really wouldn't want it any other way.”

“The treatment of the indeterminacy principle as absolute and final can then be criticized as constituting an arbitrary restriction on scientific theories, since it does not follow from the quantum theory as such, but rather from the assumption of the unlimited validity of certain of its features, an assumption that can in no way ever be subjected to experimental proof.”

“He [Aristotle] pointed out that people who had become initiates in the various mystery religions were not required to learn any facts 'but to experience certain emotions and to be put in a certain disposition.' Hence his famous literary theory that tragedy effected a purification (katharsis) of the emotions of terror and pity that amounted to an experience of rebirth.”

“We have seen that in certain respects operant reinforcement resembles the natural selection of evolutionary theory. Just as genetic characteristics which arise as mutations are selected or discarded by their consequences, so novel forms of behavior are selected or discarded through reinforcement.”

“There exists in society a very special class of persons that I have always referred to as the Believers. These are folks who have chosen to accept a certain religion, philosophy, theory, idea or notion and cling to that belief regardless of any evidence that might, for anyone else, bring it into doubt. They are the ones who encourage and support the fanatics and the frauds of any given age. No amount of evidence, no matter how strong, will bring them any enlightenment. They are the sheep who beg to be fleeced and butchered, and who will battle fiercely to preserve their right to be victimized.”

“The truly educated man is not a man who knows a bit of everything, not even the man who knows all the details of all subjects (if such a thing were possible): the “whole man” in fact, may have little detailed knowledge of facts and theories...but he will be truly in touch with the centre. He will not be in doubt about his basic convictions, about his view on the meaning and purpose of his life. He may not be able to explain these matters in words, but the conduct of his life will show a certain sureness of touch which stems from this inner clarity.”

“In certain circumstances, financial markets can affect the so-called fundamentals which they are supposed to reflect. When that happens, markets enter into a state of dynamic disequilibrium and behave quite differently from what would be considered normal by the theory of efficient markets. Such boom/bust sequences do not arise very often, but when they do, they can be very disruptive, exactly because they affect the fundamentals of the economy.”

“If a psychological Maxwell devises a general theory of mind, he may make it possible for a psychological Einstein to follow with a theory that the mental and the physical are really the same. But this could happen only at the end of a process which began with the recognition that the mental is something completely different from the physical world as we have come to know it through a certain highly successful form of detached objective understanding. Only if the uniqueness of the mental is recognized will concepts and theories be devised especially for the purpose of understanding it.”

“This is often the way it is in physics - our mistake is not that we take our theories too seriously, but that we do not take them seriously enough. It is always hard to realize that these numbers and equations we play with at our desks have something to do with the real world. Even worse, there often seems to be a general agreement that certain phenomena are just not fit subjects for respectable theoretical and experimental effort.”

“I believe we should really take our own phenomenology more seriously. What a good theory of conscious must explain is the variance in this subjective sense of realness: There clearly is a phenomenology of "hyperrealness", for example during religious experiences or under the influence of certain psychoactive substances.”

“Constraint theory argues a number of things. First, that the impossible has to be identified. Second, that the actor is then constrained by circumstances to act a certain way. For example, should we invade ISIS? Can we invade ISIS? What would it take to invade ISIS? Once you ask that question you discover the price of that option and then you take a look at American politics and see that the country is probably not prepared to invest the 2 to 3 million people that it would take to defeat ISIS and the insurgency afterwards. All right, so that's not going to happen.”

“Bealer argues that the kind of naturalistic view which Quine holds will rob him of the ability to make the normative claims which (many) naturalists wish to make in epistemology. I don't think this is right about Quine, but I'm certain it's not right about my own view. To the extent that I can show that talk of knowledge is firmly rooted within empirical theories where it plays an important explanatory role, I thereby demonstrate its naturalistic credentials.”

“We went to the moon using just Newton's laws of motion and gravity. Newtonian dynamics we call it. So then we find out, "Well, this works because there's certain regimes we've never tested it in." Had we done so, we would show that it didn't work: For example, at very high speeds, very high gravity, Newton's laws fail. They just fail. You need Einstein's laws of motion and gravity. Those would be his special theory of relativity and general theory of relativity. Now you invoke those and it works.”
