“There is, therefore, both positive and negative proof in favour of my mental and suggestive theory, and in opposition to the magnetic, occult, or electric theories of the Mesmerists and electro-biologists. My theory, moreover, has this additional recommendation, that it is level to our comprehension, and adequate to account for all which is demonstrably true, without offering any violence to reason and common sense, or being at variance with generally admitted physiological and psychological principles.”

“The concept of 'measurement' becomes so fuzzy on reflection that it is quite surprising to have it appearing in physical theory at the most fundamental level… does not any analysis of measurement require concepts more fundamental than measurement? And should not the fundamental theory be about these more fundamental concepts?”

“…the power to control the supply of money, which is one of the fundamental aspects of sovereignty, has passed from government into other hands; and therefore new institutions must be set up which will in effect exercise some of the major functions of government. They would set the level of public expenditure, and settle fiscal policy, the exercise of taxing and borrowing powers of the state, since these are indisputedly the mechanism by which the money supply is determined. But they would do more than this. They would be supreme over the economic ends and the social structure of society: for by fixing prices and incomes they would have to replace the entire automatic system of the market and supply and demand—be that good or evil—and put in its place a series of value judgments, economic or social, which they themselves would have to make…There is a specific term for this sort of polity. It is, of course, totalitarian, because it must deliberately and consciously determine the totality of the actions and activities of the members of the community; but it is a particular kind of totalitarian regime, one, namely, in which authority is exercised and the decisions are taken by a hierarchy of unions or corporations—to which, indeed, on this theory the effective power has already passed. For this particular kind of totalitarianism the Twentieth Century has a name. That name is "fascist."”

“Each worldview was a cultural product, but evolution is true and separate creation is not. […] Worldviews are social constructions, and they channel the search for facts. But facts are found and knowledge progresses, however fitfully. Fact and theory are intertwined, and all great scientists understand the interaction.”

“It was found [in the 1970s], unexpectedly and without anyone really having a concept for it, that the rules of perturbation theory can be changed in a way that makes relativistic quantum gravity inevitable rather than impossible. The change is made by replacing point particles by strings. Then Feynman graphs are replaced by Riemann surfaces, which are smooth - unlike the graphs, which have singularities at interaction vertices. The Riemann surfaces can degenerate to graphs in many different ways. In field theory, the interactions occur at the vertices of a Feynman graph. By contrast, in string theory, the interaction is encoded globally, in the topology of a Riemann surface, any small piece of which is like any other. This is reminiscent of how non-linearities are encoded globally in twistor theory.”

“The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena. The verbal interpretation, on the other hand – i. e., the metaphysics of quantum theory – is on far less solid ground.

“The characteristic activity of science is not construction, but induction. The more often something has occurred in the past, the more certain that it will in all the future. Knowledge relates solely to what is and to its recurrence. New forms of being, especially those arising from the historical activity of man, lie beyond empiricist theory. Thoughts which are not simply carried over from the prevailing pattern of consciousness, but arise from the aims and resolves of the individual, in short, all historical tendencies that reach beyond what is present and recurrent, do not belong to the domain of science.”

“Contrary to generations of western progressives, it was not Russian backwardness or mistakes in applying Marxian theory that produced the society that Lyons observed. Similar regimes came into being wherever the communist project was attempted. Lenin’s Russia, Mao’s China, Ceausescu’s Romania and many more were variants of a single dictatorial model. From being a movement aiming for universal freedom, communism turned into a system of universal despotism. That is the logic of utopia. If 1984 is such a powerful myth, one reason is that it captures this truth. Yet there is a flaw in Orwell’s story, which emerges in his picture of the all-powerful interrogator. The dystopia of perpetual power is a fantasy, and so is O’Brien. Soviet torturers were sweating functionaries living in constant fear. Like their victims, they knew that they were resources that would be used up in the service of power. There was no inner-party elite safe from the contingencies of history.”

“The example we would do well to keep in front of us is that of the Dalai Lama. He was giving a discourse on a Tibetan text about meditation. He read out a sentence, laughed and remarked, ‘Buddhist theories of creation, a disgrace! Must throw them out!’ He advises that we should keep a wastepaper basket nearby – whatever doesn’t accord with what we know now, we should cast into that basket. ‘Buddhism must face facts,’ that is what he teaches. Accordingly, he has opened Buddhist texts to minute examination. (…) That reflects confidence in one’s tradition. That is true service to the tradition. That is the way to preserve for the future ‘the pearl of great price’ in it.”

“The new attitude of the critic toward the artist has been rationalized for me by a leading European art historian who is also an influential critic of current art. It is based on a theory of division of labor in making art history. The historian, he contends, knows art history and, in fact, creates it; the artist knows only how to do things. Left to himself, the artist is almost certain to do the wrong thing — to deviate from the line of art history and thus to plunge into oblivion. The critic's role is to steer him in the proper direction and advise changes in his technique and subject matter that will coordinate his efforts with the forces of development. Better still, critics should formulate historically valid projects for artists to carry out. That not all critics have the same expectations of the future of art does not, I realize, weaken the cogency of my colleague's argument. The surviving artist would be one who has been lucky enough to pick the winning critic. My own view that art should be left to artists seemed to my mentor both out-of-date and irresponsible.”

“This paper integrates elements from the theory of agency, the theory of property rights and the theory of finance to develop a theory of the ownership structure of the firm. We define the concept of agency costs, show its relationship to the 'separation and control' issue, investigate the nature of the agency costs generated by the existence of debt and outside equity, demonstrate who bears the costs and why, and investigate the Pareto optimality of their existence. We also provide a new definition of the firm, and show how our analysis of the factors influencing the creation and issuance of debt and equity claims is a special case of the supply side of the completeness of markets problem.”

“The international disputes which united and divided Luxemburg, Lenin, Lukács, Gramsci, Bordiga or Trotsky on these issues represent the last great strategic debate in the European workers’ movement. Since then, there has been little significant theoretical development of the political problems of revolutionary strategy in metropolitan capitalism that has had any direct contact with the masses. The structural divorce between original Marxist theory and the main organizations of the working class in Europe has yet to be historically resolved. The May-June revolt in France, the upheaval in Portugal, the approaching dénouement in Spain, presage the end of this long divorce, but have not accomplished it. The classical debates, therefore, still remain in many respects the most advanced limit of reference we possess today. It is thus not mere archaism to recall the strategic confrontations which occurred four or five decades ago. To reappropriate them, on the contrary, is a step towards a Marxist discussion that has the—necessarily modest—hope of assuming an ‘initial shape’ of correct theory today. Régis Debray has spoken, in a famous paragraph, of the constant difficulty of being contemporary with our present. In Europe at least, we have yet to be sufficiently contemporary with our past.”

“Many of us believed in the possibility of a principled explanation for the laws of nature. We hoped to discover a short list of principles, which could be realized in a unique theory, which would retrodict the standard model and uniquely predict the physics to be discovered beyond it. The shocking implication of the results of Strominger reported in 1986 was that it was not to be, at least within the confines of string theory. …String theory offered more, however… It offered the promise of a setting in which the different perturbative string theories are realized as expansions around solutions of a still more fundamental theory. …That more fundamental theory would have to be background independent…”

“The object of this paper is fivefold. The first objective is to derive a practical system of demand equations which possess properties usually considered desirable from the standpoint of elementary economic theory. The second is to consider the statistical problems involved in applying the system of equations. The third is to analyse the pattern of demand for consumers' goods in terms of this system on the basis of annual data relating to the United Kingdom over the years 1920-38. The fourth is to compare the results of this system, and systems like it, with the actual state of demand in 1900. Finally, the fifth is to compare the post-war structure of demand with what might be expected from the inter-war relationshipp under free-market condition.”

“If the basic assumption of the theory of ideology is at all tenable, namely, that the general power relations embodied in our social structures can exert a distorting influence on the formation of our beliefs and preferences without our being aware of it, then we are definitely not going to put that kind of influence out of action by asking the agents in the society to imagine that they didn’t know their position. To think otherwise is to believe in magic: imagine you are “impartial” and you will be.

“[N]ot only must we seek the measure of motions and actions by themselves, but much more in comparison; for this is of excellent use and very general application. Now we find that the flash of a gun is seen sooner than its report is heard… and this is owing it seems to the motion of light being more rapid than that of sound. We find to that visible images are received by the sight faster than they are dismissed; thus the strings of the violin, when struck by the finger, are to appearance doubled and tripled, because the new image is received before the old one is gone; which is also why the reason why rings being spun round look like globes, and a lighted torch, carried hastily at night, seems to have a tail. And it was upon this inequality of motions in point of velocity that Galileo built his theory of flux and reflux of the sea; supposing that the earth revolved faster than the water could follow; and that the water was therefore first gathered in a heap and then fell down, as we see in a basin of water moved quickly. But this he devised upon an assumption which cannot be allowed, viz. that the earth moves; and also without being well informed as to the sexhorary motion of the tide.”

“Part of the downfall came early and on theoretical grounds, with the realization that real-world information lags for aggregate variables like the price level and money supply were much too short to rationalize the persistent multiyear deviations from equilibrium that seemed to characterize business cycles in most industrialized countries. The second dubious assumption, continuous market clearing, was viewed more critically once it was recognized that it was not an inextricable concomitant of rational expectations, especially when Stanley Fischer (1977) and Edmund Phelps and John Taylor (1977) showed that rational expectations could be embedded in a model containing real-world institutional features like multiperiod wage and price contracts to generate nonmarket-clearing behavior. Once Fischer and Phelps-Taylor had shown that rational expectations by itself was a necessary but not a sufficient condition to validate new-classical policy conclusions, the race was on to develop the new-Keynesian theory based on rational expectations and one or another institutional impediment to continuous market clearing.”

Pure mathematics, being mere tautology, and pure physics, being mere fact, could not have engendered them; for creatures to live, must sense the useful and the good; and engines to run must have energy available as work : and both, to endure, must regulate themselves.

“Why do we forget our childhood? With rare exceptions we have no memory of our first four, five, or six years, and yet we have only to watch the development of our own children during this period to realize that these are precisely the most exciting, the most formative years of life. Schachtel’s theory is that our infantile experiences, so free, so uninhibited, are suppressed because they are incompatible with the conventions of an adult society which we call ‘civilized’. The infant is a savage and must be tamed, domesticated. The process is so gradual and so universal that only exceptionally will an individual child escape it, to become perhaps a genius, perhaps the selfish individual we call a criminal. The significance of this theory for the problem of sincerity in art (and in life) is that occasionally the veil of forgetfulness that hides our infant years is lifted and then we recover all the force and vitality that distinguished our first experiences—the ‘celestial joys’ of which Traherne speaks, when the eyes feast for the first time and insatiably on the beauties of God’s creation. Those childhood experiences, when we ‘enjoy the World aright’, are indeed sincere, and we may therefore say that we too are sincere when in later years we are able to recall these innocent sensations.”

“To Namier it had seemed obvious that political theories act as the merest ex post facto rationalisations of political behaviour. If we are looking for explanations of political action, he maintained, we must seek them at the level of ‘the underlying emotions, the music, to which ideas are a mere libretto, often of very inferior quality’. For critics of Namier such as Sir Herbert Butterfield, the only possible retort seemed to be to go back to a famous dictum of Lord Acton’s to the effect that ideas are often the causes rather than the effects of public events. But this response duly incurred the scorn of Namier and his followers for the alleged naiveté of supposing that political actions are ever genuinely motivated by the principles used to rationalise them.”

“Relativism is a product of the modern historical-sociological procedure which is based on the recognition that all historical thinking is bound up with the concrete position in life of the thinker [Standortsgebundenheit des Denkers]. But relativism combines this historical-sociological insight with an older theory of knowledge which was as yet unaware of the interplay between conditions of existence and modes of thought, and which modelled its knowledge after static prototypes such as might be exemplified by the proposition 2 x 2 = 4. This older type of thought, which regarded such examples as the model of all thought, was necessarily led to the rejection of all those forms of knowledge which were dependent upon the subjective standpoint and the social situation of the knower, and which were, hence, merely "relative."”

“If Walter Bagehot was right that “one of the greatest pains to human nature is the pain of a new idea,” Ken caused an extraordinary amount of pain. Both in his economic thinking and in his political activities, he was dedicated to resisting, and where possible overturning, what he famously called “conventional wisdom” (one of his many turns of phrase that have since become commonplace locutions). Rejecting the standard economic theory based on small, anonymous households and firms that autonomously engage in perfectly functioning markets, Ken instead saw an economic stage dominated by large, nameable actors: big business, big labor, big government. Sorting out their roles and respective power was central to his analysis, and the continually shifting tensions in the interplay among them—“countervailing power” in another of his deft phrases—was the real story of how an economy behaved.”

“Personally, I never met Knut Wicksell. I saw him once when he delivered a lecture in Oslo, but being an unassuming student at the time, I did not have the courage to talk to him. So my knowledge of his theory came only through his writings. That, however, was a very intense and absorbing form of making his acquaintance. Already from my early student days, I read his writings (in German and Swedish) avidly. And I continued to do so later.
When I started my study on Wicksell, I found that his works were not easy reading. Often it was only at the third or fourth reading that I grasped his ideas. Invariably, each new reading made me more and more enthusiastic. Sometimes it happened that I thought I had finally caught him in an inconsistency or in unclear thinking. Every time this happened, it turned out, however, that the error was mine.”

“As the natural sciences have developed to encompass increasingly complex systems, scientific rationality has become ever more statistical, or probabilistic. The deterministic classical mechanics of the enlightenment was revolutionized by the near-equilibrium statistical mechanics of late 19th century atomists, by quantum mechanics in the early 20th century, and by the far-from-equilibrium complexity theorists of the later 20th century. Mathematical neo-Darwinism, information theory, and quantitative social sciences compounded the trend. Forces, objects, and natural types were progressively dissolved into statistical distributions: heterogeneous clouds, entropy deviations, wave functions, gene frequencies, noise-signal ratios and redundancies, dissipative structures, and complex systems at the edge of chaos.”

As quoted in My Universe : A Transcendent Reality (2011) by Alex Vary, Part II

“These individual actions are really trans-actions instead of either individual behavior or the "exchange" of commodities. It is this shift from commodities and individuals to transactions and working rules of collective action that marks the transition from the classical and hedonic schools to the institutional schools of economic thinking. The shift is a change in the ultimate unit of economic investigation. The classic and hedonic economists, with their communistic and anarchistic offshoots, founded their theories on the relation of man to nature, but institutionalism is a relation of man to man. The smallest unit of the classic economists was a commodity produced by labor. The smallest unit of the hedonic economists was the same or similar commodity enjoyed by ultimate consumers. One was the objective side, the other the subjective side, of the same relation between the individual and the forces of nature. The outcome, in either case, was the materialistic metaphor of an automatic equilibrium, analogous to the waves of the ocean, but personified as "seeking their level." But the smallest unit of the institutional economists is a unit of activity -- a transaction, with its participants. Transactions intervene between the labor of the classic economists and the pleasures of the hedonic economists, simply because it is society that controls access to the forces of nature, and transactions are, not the "exchange of commodities," but the alienation and acquisition, between individuals, of the rights of property and liberty created by society, which must therefore be negotiated between the parties concerned before labor can produce, or consumers can consume, or commodities be physically exchanged.”

“Imagine each family as a kind of little factory--a multiperson unit producing meals, health, skills, children, and self-esteem from market goods and the time, skills, and knowledge of its members. This is only one of the remarkable concepts explored by Gary Becker in his landmark work on the family. Becker applies economic theory to the most sensitive and fateful personal decisions, such as choosing a spouse or having children. He uses the basic economic assumptions of maximizing behavior, stable preferences, arid equilibria in explicit or implicit markets to analyze the allocation of time to child care as well as to careers, to marriage and divorce in polygynous as well as monogamous societies, to the increase and decrease of wealth from one generation to another.”

Whether strictly speaking we should not ask what kind of levers a man is made of rather than what is his temperament? How are they balanced? How much of such and such will it take to weigh them down so as to make him do so and so?”

Several other books… have also offered a general survey, although each has contributed its own special emphasis. Many conferences on the subject have been held, and a constant stream of new articles has appeared, both in documentation journals and in those in the data processing field.
Information retrieval is now recognized as a discipline, and further advances in theory are being made, What I described in the first edition as the key operation in retrieval — the subject description of documents — is being explored theoretically and experimentally, although we are still a long way from reducing this operation to rule (Chapter 3). There has been less new work on the design of descriptor languages, although ideas on the display of descriptor relations through thesauri and 'semantic maps' have been developed (Chapter 4).

“In the case of their purely concocted grand theory of pre-Muslim persecution of Buddhism by Hindus, we see our leftist historians throw all standards of source criticism to the wind. Such is their eagerness to uphold this convenient hypothesis, and their care not to endanger what little supportive testimony there is. After all, from the millennia of pre-Muslim religious pluralism in India, there are not even five testimonies of such persecution, so these few should be scrupulously kept away from criticism…. The allegation is simply repeated, and amplified, in all secularist history-books….. Incidentally, Hsuen Tsang's statement that his patron, king Harsha, worshipped both Buddha and the Hindu goods, is always carefully kept out of secularists' invocations of Hsuen Tsang's authority, as it is one more blow to the myth of Hindu-Buddhist struggle.”

“The current cosmological paradigm, the cold dark matter model with a cosmological constant, requires that the mass-energy of the Universe be dominated by invisible components: dark matter and dark energy. An alternative to these dark components is that the law of gravity be modified on the relevant scales. A test of these ideas is provided by the baryonic Tully-Fisher relation (BTFR), an empirical relation between the observed mass of a galaxy and its rotation velocity. Here, I report a test using gas rich galaxies for which both axes of the BTFR can be measured independently of the theories being tested and without the systematic uncertainty in stellar mass that affects the same test with star dominated spirals. The data fall precisely where predicted a priori by the modified Newtonian dynamics.”

Excellence is a range of differences, not a spot. Each location on the range can be occupied by an excellent or an inadequate representative—and we must struggle for excellence at each of these varied locations. In a society driven, often unconsciously, to impose a uniform mediocrity upon a former richness of excellence—where McDonald's drives out the local diner, and the mega-Stop & Shop eliminates the corner Mom and Pop—an understanding and defense of full ranges as natural reality might help to stem the tide and preserve the rich raw material of any evolving system: variation itself.”

“In a theory in which parameters are added to quantum mechanics to determine the results of individual measurements, without changing the statistical predictions, there must be a mechanism whereby the setting of one measuring device can influence the reading of another instrument, however remote. Moreover, the signal involved must propagate instantaneously, so that such a theory could not be Lorentz invariant. Of course, the situation is different if the quantum mechanical predictions are of limited validity. Conceivably they might apply only to experiments in which the settings of the instruments are made sufficiently in advance to allow them to reach some mutual rapport by exchange of signals with velocity less than or equal to that of light. In that connection, experiments of the type proposed by Bohm and Aharonov, in which the settings are changed during the flight of the particles, are crucial.”
