Quotes about theory (2998 quotes, page 6)

“Quantum theory may be formulated using Hilbert spaces over any of the three associative normed division algebras: the real numbers, the complex numbers and the quaternions. Indeed, these three choices appear naturally in a number of axiomatic approaches. However, there are internal problems with real or quaternionic quantum theory. Here we argue that these problems can be resolved if we treat real, complex and quaternionic quantum theory as part of a unified structure. Dyson called this structure the "three-fold way"…. This three-fold classification sheds light on the physics of time reversal symmetry, and it already plays an important role in particle physics.”

“In conceptual art the idea or the concept is the most important aspect of the work. When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art. This kind of art is not theoretical or illustrative of theories; it is intuitive; it is involved with all types of mental processes and it is purposeless. It is usually free from the dependence on the skill of the artist as a craftsman.”

“A reconsideration of the discussion in which I took an active part more than 40 years ago has left me with a rather depressing view of the somewhat shameful state of what has become an established part of economic science, the subject of ‘economic systems’. It appears to me that in this subject political attractiveness has been preserved by the flimsiest of arguments. The kindest thing one can say is that some well-meaning people have allowed themselves to be deceived by the vague and thoughtless language commonly used by specialists in the theory of these issues.”

The government of the United States is a compact between the sovereign members who formed it; and if there be one feature common to all the colonies planted upon the shores of America, it was the steady assertion of, and uncompromising desire for, community independence.”

“The idea that a few people have about the gene being the target of selection is completely impractical; a gene is never visible to natural selection, and in the genotype, it is always in the context with other genes, and the interaction with those other genes make a particular gene either more favorable or less favorable. In fact, Dobzhanksy, for instance, worked quite a bit on so-called lethal chromosomes which are highly successful in one combination, and lethal in another. Therefore people like Dawkins in England who still think the gene is the target of selection are evidently wrong. In the 30s and 40s, it was widely accepted that genes were the target of selection, because that was the only way they could be made accessible to mathematics, but now we know that it is really the whole genotype of the individual, not the gene. Except for that slight revision, the basic Darwinian theory hasn't changed in the last 50 years”

I tried to construct a theory of boundedly rational multigoal decision making. Together with Heinz Sauermann, I worked out an "aspiration adaptation theory of the firm" which was published as a journal article in 1962… More and more I came to the conclusion that purely speculative approaches like that of our paper of 1962 are of limited value.

“The second observation is that poetry is a universal human art. Despite post-modern theories of cultural relativism that assert there are no human universals, there exists a massive and compelling body of empirical data, collected and documented by anthropologists, linguists, and archeologists that demonstrates there is no human society, however isolated, that has not developed and employed poetry as a cultural practice. Most of this poetry, of course, has been oral poetry. Many of these cultures never developed writing. But the fact remains—and it is a demonstrable fact, not mere opinion—that every society has developed a special class of speech, shaped by apprehensible patterns of sound, namely, poetry”

“Let me tell you the story of the most successful organism of all time: this is the story of the parasite. … Early on, evolution branched into two distinct paths: independent organisms—those that exist on their own in the natural world—and parasites—organisms that live on other organisms. And it was, by far, the parasites that proved the more successful of the two branches. Today, for every independent organism in nature, there exist three parasites. … These two strains of evolution have been locked in a primordial arms race, constantly evolving to best each other for supremacy of this planet. As parasites evolve to perfect their systems against a species of host, the host evolves to evade their attack. Scientists call this theory of an eternal genetic struggle the Red Queen Hypothesis—a name taken from Lewis Carroll's Through the Looking Glass.”

“The theory of games was first formalised by Von Neumann & Morgenstern (1953) in reference to human economic behaviour. Since that time, the theory has undergone extensive development… Sensibly enough, a central assumption of classical game theory is that the players will behave rationally, and according to some criterion of self-interest. Such an assumption would clearly be out of place in an evolutionary context. Instead, the criterion of rationality is replaced by that of population dynamics and stability, and the criterion of self-interest by Darwinian fitness.”

“Even when altruism is allowed (as, for example, in Gary Becker's model of rational allocation), it is assumed that the altruistic actions are undertaken because they promote each person's own interests; there are personal gains to the altruist's own welfare, thanks to sympathy for others. No role is given to any sense of commitment about behaving well or to pursuing some selfless objective. All this leaves out, on the one hand, the evil passions that early theorists of capitalism contrasted with self-interest and, on the other, the social commitments that Kant analyzed in The Critique of Practical Reason and that Adam Smith discussed in The Theory of Moral Sentiments.”

“I just want to explain what I mean when I say that we should try to hold on to physical reality.
We are … all aware of the situation regarding what will turn out to be the basic foundational concepts in physics: the point-mass or the particle is surely not among them; the field, in the Faraday-Maxwell sense, might be, but not with certainty. But that which we conceive as existing ("real") should somehow be localized in time and space. That is, the real in one part of space, A, should (in theory) somehow "exist" independently of that which is thought of as real in another part of space, B. If a physical system stretches over A and B, then what is present in B should somehow have an existence independent of what is present in A. What is actually present in B should thus not depend the type of measurement carried out in the part of space A; it should also be independent of whether or not a measurement is made in A.
If one adheres to this program, then one can hardly view the quantum-theoretical description as a complete representation of the physically real. If one attempts, nevertheless, so to view it, then one must assume that the physically real in B undergoes a sudden change because of a measurement in A. My physical instincts bristle at that suggestion.
However, if one renounces the assumption that what is present in different parts of space has an independent, real existence, then I don't see at all what physics is supposed to be describing. For what is thought to be a "system" is after all, just conventional, and I do not see how one is supposed to divide up the world objectively so that one can make statements about parts.”

“Ever since 1953, when Russell Kirk produced its intellectual coat of arms, conservatism has been "what Edmund Burke wrote." This is the equivalent of Arthur Danto’s institutional theory of art—art is whatever the art world says it is. But it’s also a cop-out. Instead of analyzing conservatism in an Aristotelian way, instead of asking how we use the term in real life, we just describe Burke. In the process, don’t we risk fleeing into what Tanenhaus calls an "alternative universe"? If conservatives are "glaringly disconnected from the realities now besetting America," as Tanenhaus says, why is the solution to be more like a man who wore a powdered wig?

“What makes organizations so similar? We contend that the engine of rationalization and bureaucratization has moved from the competitive marketplace to the state and the professions. Once a set of organizations emerges as afield, a paradox arises: rational actors make their organizations increasingly similar as they try to change them. We describe three isomorphic processes—coercive, mimetic, and normative—leading to this outcome. We then specify hypotheses about the impact of resource centralization and dependency, goal ambiguity and technical uncertainty, and professionalization and structuration on isomorphic change. Finally, we suggest implications for theories of organizations and social change.”

“The Renaissance discovery of nature was an invention of nineteenth-century liberalism which played off the Renaissance delight in nature against the Middle Ages, in order to strike a blow at the romantic philosophy of history. For when Burckhardt says that the ‘discovery of the world and of man’was an achievement of the Renaissance, this thesis is, at the same time, an attack on romantic reaction and an attempt to ward off the propaganda designed to spread the romantic view of medieval culture. The doctrine of the spontaneous naturalism of the Renaissance comes from the same source as the theory that the fight against the spirit of authority and hierarchy, the ideal of freedom of thought and freedom of conscience, the emancipation of the individual and the principle of democracy, are achievements of the fifteenth century. In all this the light of the modern age is contrasted with the darkness of the Middle Ages.”

“Many of the greatest masters of the mathematical sciences were first attracted to mathematical inquiry by problems relating to numbers, and no one can glance at the periodicals of the present day which contain questions for solution without noticing how singular a charm such problems still continue to exert. The interest in numbers seems implanted in the human mind, and it is a pity that it should not have freer scope in this country. The methods of the theory of numbers 271 are peculiar to itself, and are not readily acquired by a student whose mind has for years been familiarized with the very different treatment which is appropriate to the theory of continuous magnitude; it is therefore extremely desirable that some portion of the theory should be included in the ordinary course of mathematical instruction at our University. From the moment that Gauss, in his wonderful treatise of 1801, laid down the true lines of the theory, it entered upon a new day, and no one is likely to be able to do useful work in any part of the subject who is unacquainted with the principles and conceptions with which he endowed it.”

The varying receptions of Wittgenstein, Tarski and Popper have influenced the development of various philosophies of science inspired by rational reconstruction, on the one hand, and by encyclopedic models on the other.”

“While studying antiaircraft fire control, Wiener may have conceived the idea of considering the operator as part of the steering mechanism and of applying to him such notions as feedback and stability, which had been devised for mechanical systems and electrical circuits. No doubt this kind of analogy had been operative in Wiener’s mathematical work from the beginning and sometimes had even been productive. As time passed, such flashes of insight were more consciously put to use in a sort of biological research for which Wiener consulted all kinds of people, except mathematicians, whether or not they had anything to do with it. Cybernetics, or Control and Communication in the Animal and the Machine (1948) is a rather eloquent report of these abortive attempts, in the sense that it shows there is not much to be reported. The value and influence of Cybernetics, and other publications of this kind, should not, however, be belittled. It has contributed to popularizing a way of thinking in communication theory terms, such as feedback, information, control, input, output, stability, homeostasis, prediction, and filtering. On the other hand, it also has contributed to spreading mistaken ideas of what mathematics really means”

“A question which has long troubled astronomers and physicists is what becomes of the energy that is continually being poured out into space by the sun and the stars. To this question a complete answer is given by the new theory. It is used up, diluted, or degraded, by the expansion of the universe. …the light travelling through the expanding universe and, so to say, trying to reach a particular star, or stellar system, which is continually receding with great velocity, is losing energy in trying to catch up with it. It is this degradation of the light, technically known as the redshift of the spectral lines, by which we become aware of the receding velocities of the extra-galactic nebulae. It can be shown that the decrease of the total amount of radiant energy in the universe by this degradation exceeds the increase by the radiation of the stars. It would not be correct, however, to conclude that the expansion is caused by the energy thus lost by the radiation…”

“Now, consciousness. That’s a fun thing, isn’t it? Product of an arms race between predators and prey. If you watch a cat creeping up on a mouse, you’ll be able to impute to the cat intentions that are most easily explained by the cat having a theory of mind concerning the mouse—an internal simulation of the mouse’s likely behavior when it notices the predator. Which way to run, for example. And the cat will use its theory of mind to optimize its attack strategy. Meanwhile, prey species that are complex enough to have a theory of mind are at a defensive advantage if they can anticipate a predator’s actions. Eventually this very mammalian arms race gave us a species of social ape that used its theory of mind to facilitate signaling—so the tribe could work collectively—and then reflexively, to simulate the individual’s own inner states. Put the two things together, signaling and introspective simulation, and you’ve got human-level consciousness, with language thrown in as a bonus—signaling that transmits information about internal states, not just crude signals such as ‘predator here’ or ‘food there.”

“To my complete surprise, that exposure to out-of-date scientific theory and practice radically undermined some of my basic conceptions about the nature of science and the reasons for its special success.
Those conceptions were ones I had previously drawn partly from scientific training itself and partly from a long-standing avocational interest in the philosophy of science. Somehow, whatever their pedagogic utility and their abstract plausibility, those notions did not at all fit the enterprise that historical study displayed. Yet they were and are fundamental to many discussions of science, and their failures of verisimilitude therefore seemed thoroughly worth pursuing. The result was a drastic shift in my career plans, a shift from physics to history of science and then, gradually, from relatively straightforward historical problems back to the more philosophical concerns that had initially led me to history.”

The simplistic form of the quantity theory of money that they hold is not tenable; but they are overwhelmingly right in insisting on how much "money matters," and they are right in insisting that in most circumstances, and over the long run, it is the quantity of money that is most influential in determining the purchasing power of the monetary unit. Other things being equal, the more dollars that are issued, the smaller becomes the value of each individual dollar. So at the moment the monetarists are more effective opponents of further inflation than the great bulk of politicians and even putative economists who still fail to recognize this basic truth.”

“A number of proposals have been advanced in recent years for the development of ‘general systems theory’ which, abstracting from properties peculiar to physical, biological, or social systems, would be applicable to all of them. We might well feel that, while the goal is laudable, systems of such diverse kinds could hardly be expected to have any nontrivial properties in common. Metaphor and analogy can be helpful, or they can be misleading. All depends on whether the similarities the metaphor captures are significant or superficial.
It may not be entirely vain, however, to search for common properties among diverse kinds of complex systems… The ideas of feedback and information provide a frame of reference for viewing a wide range of situations, just as do the ideas of evolution, of relativism, of axiomatic method, and of operationalism… hierarchic systems have some common properties that are independent of their specific content…”

“But it never occurred to him to want to be a philosopher, or dedicate himself to Speculation; he was still too fickle for that. True, he was not drawn now to one thing and now to another – thinking was and remained his passion – but he still lacked the self-discipline required for acquiring a deeper coherence. Both the significant and the insignificant attracted him equally as points of departure for his pursuits; the result was not of great consequence – only the movements of thought as such interested him. Sometimes he noticed that he reached one and the same conclusion from quite different starting points, but this did not in any deeper sense engage his attention. His delight was always just to be pressing on; wherever he suspected a labyrinth, he had to find the way. Once he had started, nothing could bring him to a halt. If he found the going difficult and became tired of it before he ought, he would adopt a very simple remedy – he would shut himself up in his room, make everything as festive as possible, and then say loudly and clearly: I will do it. He had learned from his father that one can do what one wills, and his father’s life had not discredited this theory. Experiencing this had given Johannes indescribable pride; that there could be something one could not do when one willed it was unbearable to him. But his pride did not in the least indicate weakness of will, for when he had uttered these energetic words he was ready for anything; he then had a still higher goal – to penetrate the intricacies of the problem by force of will. This again was an adventure that inspired him. Indeed his life was in this way always adventurous. He needed no woods and wanderings for his adventures, but only what he possessed – a little room with one window.”

“The realization that systems are integrated wholes that cannot be understood by analysis was even more shocking in physics than in biology. Ever since Newton, physicists had believed that all physical phenomena could be reduced to the properties of hard and solid material particles. In the 1920s, however, quantum theory forced them to accept the fact that the solid material objects of classical physics dissolve at the subatomic level into wavelike patterns of probabilities. These patterns, moreover, do not represent probabilities of things, but rather probabilities of interconnections. The subatomic particles have no meaning as isolated entities but can be understood only as interconnections, or correlations, among various processes of observation and measurement. In other words, subatomic particles are not “things” but interconnections among things, and these, in turn, are interconnections among other things, and so on. In quantum theory we never end up with any “things”; we always deal with interconnections.”

However, the new conception of the universe that has emerged from modern physics does not mean that Newtonian physics is wrong, or that quantum theory, or relativity theory, is right.

“Supergravity theories generically contain non-compact global symmetry groups. The general rule is that the scalar fields of the theory in question parametrize a symmetric space. Thus, if the non-compact symmetry group is G, and its maximal compact subgroup is H, the scalar fields map the space-time into the symmetric space G/H, and the number of scalar fields is dim G – dim H. The first supergravity example of this type to be found, N = 4 supergravity is one of the most interesting. In this case there are two scalar fields and the symmetric space is SL(2,R)/SO(2).”

I realised that there was a chance to work out my ideas. Time was no longer limited. I was no longer a slave to the hands of the clock. Genius is experience. Some seem to think that it is a gift or talent, but it is the fruit of long experience in many lives. Some are older souls than others, and so they know more.
