“Our theories stand. We both see clearly; we know what’s right. Even if it’s not always possible to act on it, don’t you think it matters to be able to call things by their true names?”

“Thought based on images can be neither abstract nor critical. … again in this case intellectuals have worked out theories to justify the inevitable. For unconsciously, they could not avoid being subjected to the enormous weight of billions of images (just like other people). Yet consciously, they were well aware that maintaining the demands of critical and independent thought involves a complete break with the rest of humankind. This would make it impossible for them to play their role as genuine intellectuals. They must think like everyone else if they expect to be at all believed by the masses. Thus their conscious and unconscious minds agree in taking them down the path of thought that involves images, evidence, and emotivity.”

“Earlier fundamental work of Whitehead, Russell, Wittgenstein, Carnap, Whorf, etc., as well as my own attempt to use this earlier thinking as an epistemological base for psychiatric theory, led to a series of generalizations: That human verbal communication can operate and always does operate at many contrasting levels of abstraction. These range in two directions from the seemingly simple denotative level (“The cat is on the mat”). One range or set of these more abstract levels includes those explicit or implicit messages where the subject of discourse is the language. We will call these metalinguistic (for example, “The verbal sound ‘cat’ stands for any member of such and such class of objects”, or “The word, ‘cat’ has no fur and cannot scratch”). The other set of levels of abstraction we will call metacommunicative (e. g., “My telling you where to ﬁnd the cat was friendly”, or “This is play”). In these, the subject of discourse is the relationship between the speakers. It will be noted that the vast majority of both metalinguistic and metacommunicative messages remain implicit; and also that, especially in the psychiatric interview, there occurs a further class of implicit messages about how metacommunicative messages of friendship and hostility are to be interpreted.”

“I want a poetry that can learn as much from popular culture as from serious culture. A poetry that seeks the pleasure and emotionality of the popular arts without losing the precision, concentration, and depth that characterize high art. I want a literature that addresses a diverse audience distinguished for its intelligence, curiosity, and imagination rather than its professional credentials. I want a poetry that risks speaking to the fullness of our humanity, to our emotions as well as to our intellect, to our senses as well as our imagination and intuition. Finally I hope for a more sensual and physical art — closer to music, film, and painting than to philosophy or literary theory. Contemporary American literary culture has privileged the mind over the body. The soul has become embarrassed by the senses. Responding to poetry has become an exercise mainly in interpretation and analysis. Although poetry contains some of the most complex and sophisticated perceptions ever written down, it remains an essentially physical art tied to our senses of sound and sight. Yet, contemporary literary criticism consistently ignores the sheer sensuality of poetry and devotes its considerable energy to abstracting it into pure intellectualization. Intelligence is an irreplaceable element of poetry, but it needs to be vividly embodied in the physicality of language. We must — as artists, critics, and teachers — reclaim the essential sensuality of poetry. The art does not belong to apes or angels, but to us. We deserve art that speaks to us as complete human beings. Why settle for anything less?”

“The decisive weakness in neoclassical and neo-Keynesian economics is not the error in the assumptions by which it elides the problem of power. The capacity for erroneous belief is very great, especially where it coincides with convenience. Rather, in eliding power — in making economics a nonpolitical subject — neoclassical theory destroys its relation to the real world. In that world, power is decisive in what happens. And the problems of that world are increasing both in number and in the depth of their social affliction. In consequence, neoclassical and neo-Keynesian economics is relegating its players to the social sidelines where they either call no plays or use the wrong ones. To change the metaphor, they manipulate levers to which no machinery is attached.”

“The family is the cradle of the world’s misinformation. There must be something in family life that generates factual error. Over-closeness, the noise and heat of being. Perhaps even something deeper like the need to survive. Murray says we are fragile creatures surrounded by a world of hostile facts. Facts threaten our happiness and security. The deeper we delve into things, the looser our structure may seem to become. The family process works towards sealing off the world. Small errors grow heads, fictions proliferate. I tell Murray that ignorance and confusion can’t possibly be the driving forces behind family solidarity. What an idea, what a subversion. He asks me why the strongest family units exist in the least developed societies. Not to know is a weapon of survival, he says. Magic and superstition become entrenched as the powerful orthodoxy of the clan. The family is strongest where objective reality is most likely to be misinterpreted. What a heartless theory, I say.

“What agents would choose in certain well- defined conditions of ignorance (in the “original position”) is, for Rawls, an important criterion for determining which conception of “justice” is normatively acceptable. Why should we agree that choice under conditions of ignorance is a good criterion for deciding what kind of society we would wish to have? William Morris in the late nineteenth century claimed to prefer a society of more or less equal grinding poverty for all (e. g., the society he directly experienced in Iceland) to Britain with its extreme discrepancies of wealth and welfare, even though the least well-off in Britain were in absolute terms better off than the peasants and fishermen of Iceland.” This choice seems to have been based not on any absolute preference for equality (or on a commitment to any conception of fairness), but on a belief about the specific social (and other) evils that flowed from the ways in which extreme wealth could be used in an industrial capitalist society.” Would no one in the original position entertain views like these? Is Morris’s vote simply to be discounted? On what grounds? The “veil of ignorance” is artificially defined so as to allow certain bits of knowledge “in” and to exclude other bits. No doubt it would be possible to rig the veil of ignorance so that it blanks out knowledge of the particular experiences Morris had and the theories he developed, and renders them inaccessible in the original position, but one would then have to be convinced that this was not simply a case of modifying the conditions of the thought experiment and the procedure until one got the result one antecedently wanted.”

“I do feel strongly that this is nonsense! … So perhaps I could entertain future historians by saying I think all this superstring stuff is crazy and is in the wrong direction. I think all this superstring stuff is crazy and is in the wrong direction. … I don’t like it that they’re not calculating anything. … why are the masses of the various particles such as quarks what they are? All these numbers … have no explanations in these string theories – absolutely none! … I don’t like that they don’t check their ideas. I don’t like that for anything that disagrees with an experiment, they cook up an explanation—a fix-up to say, “Well, it might be true.” For example, the theory requires ten dimensions. Well, maybe there’s a way of wrapping up six of the dimensions. Yes, that’s all possible mathematically, but why not seven? When they write their equation, the equation should decide how many of these things get wrapped up, not the desire to agree with experiment. In other words, there’s no reason whatsoever in superstring theory that it isn’t eight out of the ten dimensions that get wrapped up and that the result is only two dimensions, which would be completely in disagreement with experience. So the fact that it might disagree with experience is very tenuous, it doesn’t produce anything.”

“It is probable that when future historians of economic thought look back over this century, the thirties will appear as an era of rapid development in economic theory. Not only has there been unusual activity in monetary theory, theory of value. but extensive transformations have also been made in the basic theory of value. The outstanding publications in this field are, of course, Joan Robinson's Theory of Imperfect Competition and Chamberlin's Theory of Monopolistic Competition, the first produced in Cambridge, England, and the second in Cambridge, Massachusetts. These volumes mark the explicit recognition of the theory of the firm as an integral division of economic analysis upon which rests the whole fabric of equilibrium theory. General equilibrium is nothing more than the problem of the interaction of individual economic organisms, under various conditions and assumptions; as a necessary preliminary to its solution, an adequate theory of the individual organism itself is necessary.”

“The global reach of Smith's moral and political reasoning is quite a distinctive feature of his thought, but it is strongly supplemented by his belief that all human beings are born with similar potential and, most importantly for policymaking, that the inequalities in the world reflect socially generated, rather than natural, disparities.
There is a vision here that has a remarkably current ring. The continuing global relevance of Smith's ideas is quite astonishing, and it is a tribute to the power of his mind that this global vision is so forcefully presented by someone who, a quarter of a millennium ago, lived most of his life in considerable seclusion in a tiny coastal Scottish town. Smith's analyses and explorations are of critical importance for any society in the world in which issues of morals, politics and economics receive attention. The Theory of Moral Sentiments is a global manifesto of profound significance to the interdependent world in which we live.”

“At this time it is difficult to put one's finger on any single contribution in the decade 1950 - 1960 which is comparable to those above, and yet progress has probably been even greater. From the point of view of an educator, one cannot overlook the wide distribution which has been given to these ideas. There has been remarkable progress from analysis to synthesis, always a sign of maturity in a field of analytic endeavour. There has been consolidation, for example in the establishment of a more rigorous basis for information theory; there has been unification, for example in the demonstration of the formal similarity between game theory and linear programming; there has been application to mathematically more difficult situations, for example nonlinear servo systems and information channels with memory; there has been implementation, as in commercially available computers which by any reasonable measure are hun- dreds of times more powerful than the primitive devices of 1950; there has been de-limitation of the boundaries of many of these fields.”

“At this point water-tight compartments of university specialization and theories founded on the selected isolation of facts easily break down. Specialized thinking is rarely a sufficient foundation for concrete decisions involving action. The social scientist cannot often form sound administrative judgments solely on the basis of elements which he has picked out simply because they relate directly to his particular specialty. The present emphasis on artificial subdivisions of knowledge and on specialized thinking and teaching in universities, technical schools, and colleges and the relative neglect of administrative problems involving action have a dangerously narrowing effect on graduates of these institutions. While we may and frequently do arouse the intellectual interest of students in a considerable variety of subjects intimately related to the civilization of which they are a part, we pay almost no attention to the web of cross ties among these subjects.”

“The misleading character of the accident theory is evident from the fact that even now the “error” involved from the standpoint of U. S. policy-makers and American leaders generally is neither one of purpose nor method – it is strictly a case of unexpectedly large expense. For the U. S. leadership, in other words, Vietnam is simply another, painfully large “cost over-run.” In terms of basic U. S. objectives and methods employed, in the Third World – essentially establishment of reliable client states, increasingly managed by military elites, with generous financial and military support (arms, advisors, Green Berets, and more extensive military intervention when junta control is threatened, as in Santo Domingo) – Vietnam is a facet of a completely rational policy. The policy may be vicious and catastrophic, from the perspective of the Vietnamese; and it may be a sordid and disruptive waste of human and material resources from the standpoint of the real interests of the ordinary American; but to the Rostows, Westmorelands and Nixons, the Vietnam War is a noble endeavor (“one of our finest moments”) that we cannot afford to abandon without achieving our original ends. The evidence is compelling that this leadership is entirely capable of destroying every village in Vietnam (and in the process, every Vietnamese) if this is required to attain the original political objectives.”

Nothing else has a baggage-free description. In other words, we all live in a gigantic mathematical object—one that’s more elaborate than a dodecahedron, and probably also more complex than objects with intimidating names such as Calabi-Yau manifolds, tensor bundles and Hilbert spaces, which appear in today’s most advanced physics theories.

“The view I have just sketched of the relationships between the most general types—the forms of social life—and human nature is based upon two key ideas that might appear contradictory. The first notion holds that there exists a limited fund of problems and possibilities of human association. Each form of social life is defined by the way it responds to the problems and pursues the possibilities. The fact that the fund is limited makes comprehensive theory and universal comparison possible. This principle, however, seems incompatible with the other half of my thesisː that the forms of social life are constituents and re-creators, rather than just examples, of human nature. ¶ The way to reconcile these two equally important ideas is to conceive of human nature as an entity embodied in particular forms of social life, though never exhausted by them. Consequently, humanity can always transcend any one of the kinds of society that develop it in a certain direction. Nonetheless, human nature is known, indeed it exists, only through the historical types of social life.”

“In a sense the present work is to be regarded as a secondary-study of the work of a group of writers in the field of social theory. But the genus "secondary study" comprises several species; of these an example of only one, and that perhaps not the best known, is to be found in these pages.
The primary aim of the study is not to determine and state in summary form what these writers said or believed about the subjects they wrote about. Nor is it to inquire directly with reference to each proposition of their "theories" whether what they have said is tenable in the Hght of present sociological and related knowledge. Both these questions must be asked repeatedly, but what is important is not so much the fact that they are asked, or even answered, but the context in which this takes place.”

“Much of the present unpopularity of the theory of Americanization is due to confusion in men's minds. It has grown with such rapidity that this has been inevitable. One thinks it is summed up in learning the English language; another thinks it is achieved by becoming an American citizen; a third, that it is adopting American clothes and manners and associating with native Americans; and a fourth, that it means that everybody should be able to sing "The Star Spangled Banner". The means of Americanization are still confused with its essence. While the necessary things were being done each day to help win the war, people were asking : Can we work intelligently and effectively together in a national effort, without agreement as to the definition, the substance, and the form of Americanization? What are the probabilities of success if these matters are left to the individual determination of the thousands of persons and of agencies now at work Americanizing the 2400 or more communities having foreign-born residents? They are beginning to ask what will be the final indestructible definitions and principles of Americanization and what are to be its finally approved methods. So early in the experiment the answers can only be postulated.”

“The idea that consciousness is a mystery is a prejudice inherited from monotheism. The early seventeenth-century French philosopher René Descartes believed that animals other than humans are insensate machines. Obviously, this was a restatement in rationalist terms of the Christian belief that only humans have souls. Even if mind and matter were categorically distinct, that would not mean humans alone have minds. It was reported that in order to test his theories, Descartes used to throw animals out of the window and observe their reactions. Looking at behaviour of this kind, one might reasonably conclude that humans are the senseless machines.”

In economic theory, especially, the subject is almost completely ignored. This is not, I think, because economists regard mankind as basically selfish or even because economic man is supposed to act only in his self-interest; it is rather because economics has essentially grown up around the phenomenon of exchange and its theoretical structure rests heavily on this process.”

“[Neoinstitutional Economics…] theory has made an indispensable contribution in recent times to advances of understanding in this area. But it seems to me that in the economics of institutions theory is now outstripping empirical research to an excessive extent. No doubt the same could be said of other fields in economics, but there is a particular point about this one. Theoretical modelling may or may not be more difficult in this field than in others, but empirical work is confronted by a special difficulty. Because economic institutions are complex, they do not lend themselves easily to quantitative measurement. Even in the respects in which they do, the data very often are not routinely collected by national statistical offices. As a result, the statistical approach which has become the bread and butter of applied economics is not straightforwardly applicable. Examples of it do exist, the literature on the economics of slavery being perhaps the most fully developed - not surprisingly because slavery is an institution that is sharply defined. But to a large extent the empirical literature has consisted of case-studies which are interesting but not necessarily representative, together with a certain amount on legal court cases, which are almost certainly not representative. Is this the best we can do? There is a challenge here on the empirical side to economists to see what is the best way forward.”

“An important object of the Journal should be the publication of papers dealing with attempts at statistical verification of the laws of economic theory, and further the publication of papers dealing with the purely abstract problems of quantitative economics, such as problems in the quantitative definition of the fundamental concepts of economics and problems in the theory of economic equilibrium.
The term equilibrium theory is here interpreted as including both the classical equilibrium theory proceeding on the lines of Walras, Pareto, and Marshall, and the more general equilibrium theory which is now beginning to grow out of the classical equilibrium theory, partly through the influence of the modern study of economic statistics. Taken in this broad sense the equilibrium problems include virtually all those fundamental problems of production, circulation, distribution and consumption, which can be made the object of a quantitative study. More precisely: The equilibrium theory in the sense here used is a body of doctrines that treats all these problems from a certain point of view, which is contrasted on one side with the verbal treatment of economic problems and on the other side with the purely empirical-statistical approach to economic problems”

“The consolidation of State capitalism in Russia itself was the determining basis for the character of the Communist Party. Whilst in its foreign propaganda it continued to speak of communism and world revolution, decried capitalism, called upon the workers to join in the fight for freedom, the workers in Russia were a subjected and exploited class, living mostly in miserable working conditions, under a strong and oppressive dictatorial rule, without freedom of speech, of press, of association, more strongly enslaved than their brethren under Western capitalism. Thus an inherent falsehood must pervade politics and teachings of that party. … The doctrine it taught under the name of Marxism was not the theory of the overthrow of highly developed capitalism by a highly developed working class, but its caricature. … The Communist Party did not intend to make the workers independent fighters capable by their force of insight themselves to build their new world, but to make them obedient followers ready to put the party into power.”

“As it had been explained to David long ago, genetic diversity was very, very important. The more diverse the human gene pool was, the better were humanity’s chances of adapting to any new and unexpected conditions it might encounter, now that it was beginning to push outward into Space, to say nothing of surviving any unexpected natural disasters such as polar shifts or meteor strikes on Earth.
Unfortunately, humanity had been both unlucky and foolish. Out of the dozens of races that had once lived in the world, only a handful had survived into modern times. Some ancient races had been rendered extinct by war. Some had been simply crowded out, retreating into remote regions and forced to breed amongst themselves, which killed them off with lethal recessives.
That had been the bad luck. The foolishness had come when people began to form theories about the process of Evolution. They got it all wrong: most people interpreted the concept of “survival of the fittest” to mean they ought to narrow the gene pool, reducing it in size. So this was done, in genocidal wars and eugenics programs, and how surprised people were when lethal recessives began to occur more frequently! To say nothing of the populations who died in droves when diseases swept through them, because they were all so genetically similar there were none among them with natural immunities.”

The star collapses gravitationally and disappears from the visible universe, leaving behind only an intense gravitational field to mark its presence. The star remains in a state of permanent free fall, collapsing endlessly inward into the gravitational pit without ever reaching the bottom. … In my opinion, the black hole is incomparably the most exciting and the most important consequence of general relativity. But Einstein … was actively hostile to the idea of black holes. … Oddly enough, Oppenheimer too in later life was uninterested in black holes, although… they were his most important contribution to science. … Oppenheimer in his later years believed that the only problem worthy of attention of a serious theoretical physicist was the discovery of fundamental equations of physics.

“[…] Perhaps the easiest way to convince yourself is by scanning the literature of soft psychology over the last 30 years and noticing what happens to theories. Most of them suffer the fate that General MacArthur ascribed to old generals—They never die, they just slowly fade away. In the developed sciences, theories tend either to become widely accepted and built into the larger edifice of well-tested human knowledge or else they suffer destruction in the face of recalcitrant facts and are abandoned, perhaps regretfully as a “nice try.” But in fields like personology and social psychology, this seems not to happen. There is a period of enthusiasm about a new theory, a period of attempted application to several fact domains, a period of disillusionment as the negative data come in, a growing bafflement about inconsistent and unreplicable empirical results, multiple resort to ad hoc excuses, and then finally people just sort of lose interest in the thing and pursue other endeavors.”

It seems, therefore, that a general theory of systems would be a useful tool providing, on the one hand, models that can be used in, and transferred different fields, and safeguarding, on the other hand, from vague analogies which often have marred the progress in these fields.”

Ludwig von Bertalanffy (1901–1972) austrian biologist and philosopher

“.. and to think now that great mathematicians find my work interesting because I am able to illustrate their theories. They can not imagine that I was such a bad pupil in mathematics. I don't understand it myself neither. I never could understand why it was necessary to prove something that everyone already sees. I saw it, I knew it, so it is how it is… But yes, you had to prove it. I did overcome it when I realized I can make something else - I thought I was a good-for-nothing. In my family there were no other artists to find... I was just a weird duck, right?”

M. C. Escher (1898–1972) Dutch graphic artist

version in original Dutch (origineel citaat van M.C. Escher, in het Nederlands): En als je nu bedenkt dat grote wiskundigen mijn werk interessant vinden, omdat ik in staat ben hun theorieën te illustreren. Ze kunnen zich helemaal niet voorstellen dat ik zo slecht was in wiskunde. Ik snap er zelf ook niets van. Ik begreep niet dat je iets moest bewijzen wat iedereen ziet. Ik zag het, ik wist, het is toch zo.. .Maar jawel hoor, je moest het bewijzen. Ik ben er bovenuit gekomen toen ik me realiseerde, dat ik wat anders kon. Ik dacht, dat ik een nietsnut was. Ik kom uit een milieu waar geen artiesten in waren.. ..Ik was een rare eend in de bijt, he?
1960's, M.C. Escher, interviewed by Bibeb', 1968

“That austerity is a counterproductive economic policy in a situation of economic recession can be seen, rightly, as a “Keynesian critique.” Keynes did argue—and persuasively—that to cut public expenditure when an economy has unused productive capacity as well as unemployment owing to a deficiency of effective demand would tend to have the effect of slowing down the economy further and increasing—rather than decreasing—unemployment. Keynes certainly deserves much credit for making that rather basic point clear even to policymakers, irrespective of their politics, and he also provided what I would call a sketch of a theory of explaining how all this can be nicely captured within a general understanding of economic interdependences between different activities… I am certainly supportive of this Keynesian argument, and also of Paul Krugman’s efforts in cogently developing and propagating this important perspective, and in questioning the policy of massive austerity in Europe.
But I would also argue that the unsuitability of the policy of austerity is only partly due to Keynesian reasons. Where we have to go well beyond Keynes is in asking what public expenditure is for—other than for just strengthening effective demand, no matter what its content. As it happens, European resistance to savage cuts in public services and to indiscriminate austerity is not based only, or primarily, on Keynesian reasoning. The resistance is based also on a constructive point about the importance of public services—a perspective that is of great economic as well as political interest in Europe.”
