Quotes about theory (2998 quotes, page 11)

“…nor have I found occasion to depart from the plan… the rejection of the whole doctrine of series in the establishment of the fundamental parts both of the Differential and Integral Calculus. The method of Lagrange… had taken deep root in elementary works; it was the sacrifice of the clear and indubitable principle of limits to a phantom, the idea that an algebra without limits was purer than one in which that notion was introduced. But, independently of the idea of limits being absolutely necessary even to the proper conception of a convergent series, it must have been obvious enough to Lagrange himself, that all application of the science to concrete magnitude, even in his own system, required the theory of limits.”

“Sociobiology is not just any statement that biology, genetics, and evolutionary theory have something to do with human behavior. Sociobiology is a specific theory about the nature of genetic and evolutionary input into human behavior. It rests upon the view that natural selection is a virtually omnipotent architect, constructing organisms part by part as best solutions to problems of life in local environments. It fragments organisms into “traits,” explains their existence as a set of best solutions, and argues that each trait is a product of natural selection operating “for” the form or behavior in question. Applied to humans, it must view specific behaviors (not just general potentials) as adaptations built by natural selection and rooted in genetic determinants, for natural selection is a theory of genetic change. Thus, we are presented with unproved and unprovable speculations about the adaptive and genetic basis of specific human behaviors: why some (or all) people are aggressive, xenophobic, religious, acquisitive, or homosexual.”

“Voltaire remarked that it is possible to kill a flock of sheep by witchcraft if you give them plenty of arsenic at the same time. The sheep, in this figure, may well stand for the complacent apologists of capitalism; Marx's penetrating insight and bitter hatred of oppression supply the arsenic, while the labour theory of value provides the incantations.”

“Mathematics have a triple aim. They must furnish an instrument for the study of nature. But that is not all: they have a philosophic aim and, I dare maintain, an esthetic aim. They must aid the philosopher to fathom the notions of number, of space, of time. And above all, their adepts find therein delights analogous to those given by painting and music. They admire the delicate harmony of numbers and forms; they marvel when a new discovery opens to them an unexpected perspective; and has not the joy they thus feel the esthetic character, even though the senses take no part therein? Only a privileged few are called to enjoy it fully, it is true, but is not this the case for all the noblest arts?
This is why I do not hesitate to say that mathematics deserve to be cultivated for their own sake, and the theories inapplicable to physics as well as the others. Even if the physical aim and the esthetic aim were not united, we ought not to sacrifice either.”

“What we have now come to regard as typical of Middle Eastern regimes is not typical of the past. The regime of Saddam Hussein, the regime of Hafiz al Assad, this kind of government, this kind of society, has no roots either in the Arab or in the Islamic past. It is due and let me be quite specific and explicit it is due to an importation from Europe, which comes in two phases.
Phase one, the 19th century, when they are becoming aware of their falling behind the modern world and need desperately to catch up, so they adopt all kinds of European devices with the best of intentions, which nevertheless have two harmful effects. One, they enormously strengthen the power of the state by placing in the hands of the ruler, weaponry and communication undreamt of in earlier times, so that even the smallest petty tyrant has greater powers over his people than Harun al-Rashid or Suleyman the Magnificent, or any of the legendary rulers of the past.
Second, even more deadly, in the traditional society there were many, many limits on the autocracy, the ruler. The whole Islamic political tradition is strongly against despotism. Traditional Islamic government is authoritarian, yes, but it is not despotic. On the contrary, there is a quite explicit rejection of despotism. And this wasn't just in theory; it was in practice too because in Islamic society, there were all sorts of established orders in society that acted as a restraining factor. The bazaar merchants, the craft guilds, the country gentry and the scribes, all of these were well organized groups who produced their own leaders from within the group. They were not appointed or dismissed by the governments. And they did operate effectively as a constraint.”

“At present game theory has, in my opinion, two important uses, neither of them related to games nor to conflict directly. First, game theory stimulates us to think about conflict in a novel way. Second, game theory leads to some genuine impasses, that is, to situations where its axiomatic base is shown to be insufficient for dealing even theoretically with certain types of conflict situations… Thus, the impact is made on our thinking process themselves, rather than on the actual content of our knowledge.”

“Conventional economic theory is built is built on the assumption of diminishing returns. Economic actions engender a negative feedback that leads to a predictable equilibrium for prices and market shares. Such feedback tends to stabilize the economy because any major changes will be offset by the very reactions they generate. The high oil prices of the 1970s encouraged energy conservation and increased oil exploration, precipitating a predictable drop in prices by the early 1980s. According to conventional theory, the equilibrium marks the “best” outcome possible under the circumstances: the most efﬁcient use and allocation of resources.”

“I consider that Curie's Principle has two major consequences:
First: It shows that the class of processes which can be isolated for causal representation, not requiring the inference of external causes, is wider than the class of energetically closed systems. One-way processes in which the system loses energy can be isolable, in the sense that they can be given complete representation without taking their environment into account.
Second: It suggests the possibility of a geometrical physics treating 3D spatial relations, i. e., angles or lengths, as primary. Just as statistical mechanics, the theory of crystal symmetry, and Group theory in quantum mechanics, are useful without assumptions about forces, so Curie's principle, with an appropriate model, can determine the path of a one-way process without such assumptions…”

“A great many individuals ever since the rise of the mathematical method, have, each for himself, attacked its direct and indirect consequences…. I shall call each of these persons a paradoxer, and his system a paradox. I use the word in the old sense:… something which is apart from general opinion, either in subject-matter, method, or conclusion…. Thus in the sixteenth century many spoke of the earth's motion as the paradox of Copernicus, who held the ingenuity of that theory in very high esteem, and some, I think, who even inclined towards it. In the seventeenth century, the depravation of meaning took place… Phillips says paradox is "a thing which seemeth strange"—here is the old meaning…—"and absurd, and is contrary to common opinion," which is an addition due to his own time.”

“There's a human race, and different skin colors, and different racial, what we call racial characteristics. There's several theories about where those come in. Probably the best theory is that the Tower of Babel, which would have been a few hundred years after the flood, is where the races began. When god confused the languages, they went off into their small groups, all speakin' the same language. And if you get a small in-breeding group, you know, 2000 years after the creation, you're gonna get genetic disorders, and racial traits could be a result of this Tower of Babel incident. But I think that there's no question from scripture and from science that all humans are the same race, and have the same genetic code, and certainly can interbreed. So there's no reason scripturally to be a racist. You know, we all came from Adam and Eve, and then later from Noah and his family.”

“In discussing the distinction between minor inventions, whose cumulative impact is decisive in productivity growth, and major technological breakthroughs, it may be useful to draw an analogy between the history of technology and the modem theory of evolution ( … ) Some biologists distinguish between micromutations, which are small changes in an existing species and which gradually alter its features, and macromutations, which creates new species. The distinction between the two could provide a useful analogy for our purposes. I define micro inventions as the small, incremental steps that improve, adapt an extremeline existing techniques already in use, reducing costs, improving form and function, increasing durability, and reducing energy and raw material requirements. Macroinventions, on the other hand, are those inventions in which a radical new idea, without clear precedent, emerges more or less ab nihilo. In terms of sheer numbers, micro inventions are far more frequent and account for most gains in productivity. Macroinventions, however, are equally crucial in technological history.”

“Critical theory … values Freud as a non-ideological thinker and theoretician of contradictions—contradictions which his successors sought to escape and mask. … “The greatness of Freud,” wrote Adorno, “consists in that, like all great bourgeois thinkers, he left standing undissolved such contradictions and disdained the assertion of pretended harmony where the thing itself is contradictory. He revealed the antagonistic character of the social reality.” … A parallel can be established between Marx’s judgment on Ricardo and the post-Ricardians. To Marx, Ricardo was the classic and best representative of bourgeois economics since he articulated the contradictions of bourgeois society without glossing them over.”

“A major social problem we face today is how to control the political process that is eroding the free enterprise market system. Although I am pessimistic that we will in fact ever resolve this problem completely, we will surely never solve it unless we develop a viable positive theory of the political process. Such a political theory will not be complete until we also have developed a theory that explains why we get the results we do out of the mass media.”

“There is little doubt that the observation that quality may depend on price (productivity on wages; default probability on interest rates) has provided a rich mine for economic theorists: A simple modification of the basic assumptions results in a profound alteration of many of the basic conclusions of the standard paradigm. The Law of Supply and Demand has been repealed. The Law of the Single Price has been repealed. The Fundamental Theorem of Welfare Economics has been shown not to be valid.
More than that, the theories that we describe here provide the basis of progress toward a unification of macroeconomics and microeconomics. They pro vide an explanation of unemployment and credit rationing, derived from basic microeconomic principles. It is a theory in which the extensive idleness that periodically confronts society's resources, human and capital, is seen as but the most obvious example of market failures that prevasively and persistently distort the allocation of resources.”

“Biological determinism has for years struck me as a failure of intellectual nerve. So I don't mean to counter sexist theories along those lines with a mirror-image feminist version. We have as yet no truly value-free science, uninfluenced by masculinist (among other biases) prejudice. Consequently — although on certain bleak days I am sorely tempted to agreement with what we feminists have termed the "acute terminal testosterone-poisoning" theory of patriarchal history — I do not make the argument that women are inherently more peaceable, nurturing, or altruistic than men. (For one thing, this permits men the laziest of justifications for their own behavior.) Yet it is undeniable that history is a record of most women acting peaceably and of most men acting belligerently”

Robin Morgan (1941) American feminist writer

to a point where the capacity for belligerence is regarded as an essential ingredient of manhood and the proclivity for conciliation is thought largely a quality of women.

“Humankind is a lonely creature looking for connections and associations from childhood to the end of his life. This intention to join with the others can also be found in human societies. Stories, legends and most of human efforts tend to a joint and union, the same direction towards which the humankind is heading. The definition of a human being in this theory is not considered to be a good or a devil self. Man is defined as a social creature craving for establishing relationships and connections, without which he will be unable to survive. Linking up with another thing, establishing connections with God, relating to different points of view, associating with dreams and in its most general form sharing life with a spouse are all examples of this instinct in human beings. In a similar pattern, civilizations of the world are following, and will be following, the same path. This is the era of Collaboration of Civilizations, Union of Cultures, and Joining of Religions.”

“Aside from Cauchy, the greatest contributory to the theory [of determinants] was Carl Gustav Jacob Jacobi. With him the word "determinant" received its final acceptance. He early used the functional determinant which Sylvester has called the Jacobian, and in his famous memoirs in Crelle's Journal for 1841 he considered these forms as well as that class of alternating functions which Sylvester has called alternants.”

“I have lately spent some Thoughts relative to the Nature of Light, whether it be subject to the common Laws of Motion. In this particular Newton seems to contradict himself. For in his Principia Sect. 14th he applies the common Laws of Motion to account for Reflection and Refraction, as he does also in one Part of his Optics where he proves the Sine of Incid. to Sine Refr, in a given in a given Ratio. But in another Part he says, “nothing more is requisite for producing all the Variety of Colours and Degrees of Refrangibility than that the Rays of Light be Bodies of different Sizes, the least of which may make Violet, and the Greatest the Red"; this manifestly is not consistent with the Theory of Motion applied to Bodies, where the Magnitude of the Bodies is of no Consequence. Now it is evident that if the common Theory of Motion can be applied to Light, the Red Light must have had the greatest Velocity before Incidence, as it suffers the least Deviation, for if the Vels of all the Difft colour'd Light were equal before Incidence, they must by Newton's Principia Sect. Sect. 8. Prop. 1. have continued equal after, and therefore must have suffered the same Deviation. The Determination of this Point seems to be of considerable Importance, as we so often apply the Theory of Motion to Light.”

“Though he died in 1946, Keynes still dominated economics at Cambridge in the mid-1960s. It wasn't just that all the leading figures among the faculty, Richard Kahn, Joan Robinson, Brian Reddaway, David Champernowne, Nicholas Kaldor, and James Meade, had been his pupils and/or collaborators. It was the tone of the place. The study of economics, theoretical or empirical, was driven by the desire to improve the conduct of economic policy. This did not mean that pure theory was neglected. Indeed, in those years Robinson was fighting a stirring battle in the realms of high theory with Paul Samuelson and Robert Solow from the Massachusetts Institute of Technology. Nor was Cambridge innocent of the cutting edge of econometric technique. Richard Stone, who, following Keynes's suggestions, had created the first modern national income accounts, was still director of the Department of Applied Economics where much of modern econometrics was pioneered. Nonetheless, we were taught that theory and technique should serve the higher cause of rational economic policies, and to use our newly learned econometric expertise to write essays on unemployment, or inflation, or the balance of trade, or some other topic at the top of the current political agenda.”

“Replacing particles by strings is a naive-sounding step, from which many other things follow. In fact, replacing Feynman graphs by Riemann surfaces has numerous consequences: 1. It eliminates the infinities from the theory. …2. It greatly reduces the number of possible theories. …3. It gives the first hint that string theory will change our notions of spacetime. Just as in QCD, so also in gravity, many of the interesting questions cannot be answered in perturbation theory. In string theory, to understand the nature of the Big Bang, or the quantum fate of a black hole, or the nature of the vacuum state that determines the properties of the elementary particles, requires information beyond perturbation theory… Perturbation theory is not everything. It is just the way the [string] theory was discovered.”

“Cicero bent Greek ideas to his vision of the idealized Roman Republic, and his understanding of the mores—the morality and social attachments—of the gentlemanly statesmen who would hold power in a just republic. Readers familiar with Machiavelli’s Prince will hear curious echoes of that work in Cicero’s advice; curious because the pieties of Cicero’s advice to the would-be statesman were satirized by Machiavelli sixteen hundred years later. If his philosophy was Greek and eclectic, Cicero owed his constitutional theory to Polybius; he was born soon after Polybius died, and read his history. And Cicero greatly admired Polybius’s friend and employer Scipio the Younger. There are obvious differences of tone. Polybius celebrated Rome’s achievement of equipoise, while Cicero lamented the ruin of the republic. Cicero’s account of republican politics veers between a “constitutional” emphasis on the way that good institutions allow a state to function by recruiting men of good but not superhuman character, and a “heroic” emphasis on the role of truly great men in reconstituting the state when it has come to ruin. Cicero’s vanity was so notorious that everyone knew he had himself in mind as this hero—had he not saved the republic before when he quelled the conspiracy of Catiline?”

“If they leave college thinking, as they usually do, that science offers a full, accurate, and literal description of man and Nature; if they think scientific research by itself yields final answers to social problems; if they think scientists are the only honest, patient, and careful workers in the world; if they think that Copernicus, Galileo, Newton, Lavoisier, and Faraday were unimaginative plodders like their own instructors; if they think theories spring from facts and that scientific authority at any time is infallible; if they think that the ability to write down symbols and read manometers is fair grounds for superiority and pride, and if they think that science steadily and automatically makes for a better world — then they have wasted their time in the science lecture room; they live in an Ivory Laboratory more isolated than the poet's tower, and they are a plain menace to the society they belong to.

“Ultimately, in its collapse, Laos was important because it proved the validity of the so-called domino theory, which preached that communism--once victorious in South Vietnam--would metastasize throughout the region. Laos, like Cambodia, proved the domino theorists correct. On August 23, 1975, just four months after Saigon's fall, communist Pathet Lao (meaning "Land of Lao") guerrillas entered the Laotian capital of Vientiane and seized control of the nation. It was an event that, while clearly destructive to American interests in Asia, served as something of a wake-up call to those American isolationists who had downplayed the regional threat of communism. It also ushered in a horrid era for this nation's 4.8 million people.”

“We venture to say a few words in explanation of the plan of this work. Its object is not to force upon the public the personal views or theories of its author; nor has it the pretensions of a scientific work, which aims at creating a revolution in some department of thought. It is rather a brief summary of the religions, philosophies, and universal traditions of human kind, and the exegesis of the same, in the spirit of those secret doctrines, of which none — thanks to prejudice and bigotry — have reached Christendom in so unmutilated a form, as to secure it a fair judgment. Since the days of the unlucky mediaeval philosophers, the last to write upon these secret doctrines of which they were the depositories, few men have dared to brave persecution and prejudice by placing their knowledge upon record. And these few have never, as a rule, written for the public, but only for those of their own and succeeding times who possessed the key to their jargon. The multitude, not understanding them or their doctrines, have been accustomed to regard them en masse as either charlatans or dreamers. Hence the unmerited contempt into which the study of the noblest of sciences — that of the spiritual man — has gradually fallen.”

“Educators know there are only two types of schooling: indoctrination and education.
Indoctrination teaches a student how to cleave to a party line, and to recite the slogans and bromides of the accepted conformity. He is taught only how to swallow lies, and there is no assurance he will not swallow the propaganda of foes as easily as that of friends. Such folk are hopelessly provincial to their time and place. Unable to distinguish truth from fable, they swallow both or spit both out, and become zealots, or, worse yet, cynics. The zealot holds that truth can be won with no effort; the cynic, that no effort will suffice.
Education teaches the art of skeptical inquiry. The student learns the thoughts of all the great minds of the past, so that the implications and mistakes of philosophy of various schools are not unknown to him. And he learns, first, current scientific theories and, second, how frail and temporary such theories can be. He learns to be undeceived by those who claim to know a last and final truth.”

“At the beginning of each semester, I tell students that my economic theory course will deal with positive, non-normative economic theory. I also tell them that if they hear me making a normative statement without first saying, "In my opinion," they are to raise their hands and say, "Professor Williams, we didn't take this class to be indoctrinated with your personal opinions passed off as economic theory; that's academic dishonesty." I also tell them that as soon as they hear me say, "In my opinion," they can stop taking notes because my opinion is irrelevant to the subject of the class -- economic theory. Another part of this particular lecture to my students is that by no means do I suggest that they purge their vocabulary of normative or subjective statements. Such statements are useful tools for tricking people into doing what you want them to do. You tell your father that you need a cell phone and he should buy you one.

“However much the theory of political realism may have been misunderstood and misinterpreted, there is no gainsaying its distinctive intellectual and moral attitude to matters political.
Intellectually, the political realist maintains the autonomy of the political sphere, as the economist, the lawyer, the moralist maintain theirs. He thinks in terms of interest defined as power, as the economist thinks in terms of interest defined as wealth; the lawyer, of the conformity of action with legal rules; the moralist, of the conformity of action with moral principles. The economist asks: "How does this policy affect the wealth of society, or a segment of it?" The lawyer asks: "Is this policy in accord with the rules of law?" The moralist asks: "Is this policy in accord with moral principles?" And the political realist asks: "How does this policy affect the power of the nation?" (Or of the federal government, of Congress, of the party, of agriculture, as the case may be.)
The political realist is not unaware of the existence and relevance of standards of thought other than political ones. As political realist, he cannot but subordinate these other standards to those of politics.”

This is not to say that the Islamic media do not suffer from sensationalized conspiracy theories, but they probably are no more prone to those faults than their Western colleagues.”

“I make the most outrageous demands on my imagination and leave aside everything else, theory and nature study, as other people understand them. This is the only way I can work, drawing on nothing but my own faculty of imagination with I feed without stint – except in working hours.”

Franz Marc (1880–1916) German painter

Quote in Marc's letter to August Macke, 1910; as cited by de:Wolf-Dieter Dube, in Expressionism; Praeger Publishers, New York, 1973, pp. 127-28

“The quantum theory, as it is now constituted, presents us with a very great challenge, if we are at all interested in such a venture, for in quantum physics there is no consistent notion at all of what the reality may be that underlies the universal constitution and structure of matter. Thus, if we try to use the prevailing world view based on the notions of particles, we discover that the 'particles' (such as electrons) can also manifest as waves, that they move discontinuously, that there are no laws at all that apply in detail to the actual movements of individual particles and that only statistical predictions can be made about large aggregates of such particles. If on the other hand we apply the world view in which the world is regarded as a continuous field, we find that this field must also be discontinuous, as well as particle-like, and that it is as undermined in its actual behaviour as is required in the particle view of relation as a whole.”

“The Trail of Tears was where the Cherokee Indians were driven out of the Chattanooga area all the way to Oklahoma. … Evolution is responsible for what happened to the Indians. How any Indian can believe in evolution just blows my mind. … [The] evolution theory is what destroyed them.”

“[A rival theory that has to be better than the dominant “90 percent explanation” cannot go wrong very often and still stay in the contest. For the challenger of a 50 percent incumbent, some shortcomings are not that fatal. This comparative situation has to be remembered as argued by James Burnham:]… we must keep in mind an obvious principle of scientiﬁc method. To disprove the theory, it is not enough to show that it is not 100% certain, that difﬁculties confront it, and certain evidence seems to be against it. It must be further shown that it is less certain than alternative theories covering the same subject matter, that there are in its case more difﬁculties, more negative evidence than in the case of at least one alternative theory. No theory about what actually happens and will happen is ever ‘certain’.”

“The strength of a theory is not what it allows, but what it prohibits; if you can invent an equally persuasive explanation for any outcome, you have zero knowledge.”
