Theoretical Quotes

My relationship to the desecration of the earth was very theoretical and intellectual until I got sick. I could never watch anything about polar bears dying or the death of bees. There were certain things I knew I couldn't go near because they were too devastating. But I don't think until I got cancer did I get it in my body, what was happening to the earth. I finally went: "Oh! Earth! Organism!" ~ Eve Ensler

During our glorious year of 1974–5, while I was dithering over gravitational waves, and Stephen was leading our merged group in black hole research, Stephen himself had an insight even more radical than his discovery of Hawking radiation. He gave a compelling, almost airtight proof that, when a black hole forms and then subsequently evaporates away completely by emitting radiation, the information that went into the black hole cannot come back out. Information is inevitably lost.
This is radical because the laws of quantum physics insist unequivocally that information can never get totally lost. So, if Stephen was right, black holes violate a most fundamental quantum mechanical law.
How could this be? The black hole's evaporation is governed by the combined laws of quantum mechanics and general relativity - the ill-understood laws of quantum gravity; and so, Stephen reasoned, the fiery marriage of relativity and quantum physics must lead to information destruction.
The great majority of theoretical physicists find this conclusion abhorrent. They are highly sceptical. And so, for forty-four years they have struggled with this so-called information-loss paradox. It is a struggle well worth the effort and anguish that have gone into it, since this paradox is a powerful key for understanding the quantum gravity laws. Stephen himself, in 2003, found a way that information might escape during the hole's evaporation, but that did not quell theorists' struggles. Stephe ~ Stephen Hawking

He described the securities - called Abacus - to a girlfriend: I had some input into the creation of this product (which by the way is a product of pure intellectual masturbation, the type of thing which you invent telling yourself 'Well, what if we created a "thing," which has no purpose, which is absolutely conceptual and highly theoretical and which nobody knows how to price?').15 ~ John Kay

A theoretical system does not merely state facts which have been observed and that logically deducible relations to other facts which have also been observed. ~ Talcott Parsons

He will go to his grave feeling cheated, never realizing that there isn't much difference between one woman and the other, that it is the loving that creates the difference. ~ Shulamith Firestone

All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction. ~ Richard P. Feynman

All high mathematics serves to do is to beget higher mathematics. ~ Ashim Shanker

I started out in nuclear physics. But after I became more sensitized to the environmental and health implications of the nuclear system - I was being trained to be the first women in the fast-breeder reactor in India (and was in it when it first went critical) - I didn't feel comfortable with it. So I went into theoretical physics. ~ Vandana Shiva

[Skinner] does not invoke other events, processes, or mechanisms which are hypothesized or invented for the purpose of mediating between behavior and its empirical determinants. This omission is sometimes misconstrued as a denial that mediating mechanisms exist; they obviously do, they are obviously neurological and they are also obviously themselves lawful. ...The argument [against employing them as part of scientific practice] is simplicity itself... [Skinner] considers such theoretical terms unnecessary; they may generate research whose only usefulness is to disconfirm the mediating entity or redefine it without increasing our knowledge of behavior's controlling variables; they can become the absorbing focus of an inquiry and so deflect attention from behavior itself; they can become a "refuge from the data". ~ Kenneth MacCorquodale

The trick, he supposed, was never to lose sight of the theoretical possibility while not for a moment taking the idea remotely seriously. ~ Iain M. Banks

It is ironic that Keynesianism originated as a weapon to combat depression, but became universally accepted and "successful" only during (and because of!) the postwar expansion. At the first sign of renewed world recession, Keynesian theory has proved itself to be a snare and a delusion that has gone into immediate bankruptcy. The resulting "post-Keynesian synthesis" is also the theoretical reason for the reactionary exhumation of the simplistic, neoclassical, and monetarist economic theory of the 1920s. This revival of old theory is highlighted by the award of Nobel prizes in economics to Friedrich von Hayek, whose theoretical work was done before the Great Depression, and Milton Friedman, whose lone voice echoed in the wilderness until the new world economic crisis put his unpopular and antipopulist theories on the agenda of business board rooms and government cabinet rooms in one capitalist country after another. The real reason for the recent interest in fifty-year-old theories is that capital now wants them to legitimize its attack on the welfare state and "unproductive" expenditures on social services, which capital claims to need for "productive" investment in industry, including armaments. ~ Andre Gunder Frank

Shouldn't we just admit the obvious--that the New Testament call to discipleship, compassion, and giving leaves no room for the way many of us are thinking and living? Is it time to get beyond the theoretical stance of 'I'd be willing to give up anything if God asked me to,' and start actually giving up things in order to do what He's commanded us? ~ Randy Alcorn

One of the most moving narratives of modern history is the story of how men and women languishing under various forms of oppression came to acquire, often at great personal cost, the sort of technical knowledge necessary for them to understand their own condition more deeply, and so acquire some of the theoretical armoury essential to change it ... There is no reason why literary critics should not turn to autobiography or anecdotalism, or simply slice up their texts and deliver them to their publishers in a cardboard box, if they are not so politically placed as to need emancipatory knowledge. ~ Terry Eagleton

That's all very well as an abstract moral principle, Avril, a coffee-table theoretical construct, but there's no denying the sheer gratuitous pleasure to be derived from seeing members of the ruling class in pain and torment. ~ Irvine Welsh

Nothing you ever do, Eli, is meant to be theoretical. I see it in you. ~ Victoria Schwab

The ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models. ~ Lawrence M. Krauss

It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory, resulting in a very great theoretical development, are completely trivial from any point of view except their relevance to the structure of a theoretical system. ~ Talcott Parsons

Buildings are seldom just buildings in downtown Chicago, they are Examples, and not a city on Earth, I swear, is as knowledgeably preoccupied with architectural meaning. Where else would a department store include in its advertisements the name of the architect who created it, or a newspaper property section throw in a scholarly exposition of theoretical design? ~ Jan Morris

The 1980s: feminism, postmodernism, sexual/textual politics

While it might be tempting to generalise that Woolf 's writing was being discussed almost in two separate camps during the 1980s, formalists on the one hand, and feminists on the other, this would be to simplify things too far.
Many critics were attempting to make sense of and connect her feminist politics with her modernist practices. Such investigations coincided with the explosion of theory in literary studies, and once again the work of Virginia
Woolf was central to the framing of many of the major theoretical developments in literary critical engagements with feminism, postmodernism, deconstruction and psychoanalysis. In the context of the rise of 'high theory'
and the questioning of old-school Marxist, materialist, humanist and historicist literary theories, Woolf studies wrestled with the locating of her radical feminist politics in the avant-garde qualities of the text itself, and its endlessly transgressive play of signifiers, with the Woolfian inscription of radically deconstructed models of the self and of sexuality and jouissance. ~ Jane Goldman

It is surely the following kinds of question that would need to be posed:

What types of knowledge do you want to disqualify in the very instant of your demand: 'Is it a science'? Which speaking, discoursing subjects -which subjects of experience and knowledge - d you then want to 'diminish' when you say: 'I who conduct this discourse am conducting a scientific discourse, and I am a scientist'? Which theoretical-political avant garde do you want to enthrone in order to isolate it from all the discontinuous forms of knowledge that circulate about it? When I see you straining to establish the scientificity of Marxism I do not really think that you are demonstrating once and for all that Marxism has a rational structure and that therefore its propositions are the outcome of verifiable procedures; for me you are doing something altogether different, you are investing Marxist discourses and those who uphold them with the effects of a power which the West since Medieval times has attributed to science and has reserved for those engaged in scientific discourse. ~ Michel Foucault

Although they can do it all the time, you know, they're far better than me, on a musically, on a theoretical music level. You know, they're out of my league. ~ Eric Clapton

Poverty that is learned with the humble, the poor, the sick and all those who are on the existential peripheries of life. Theoretical poverty is of no use to us. Poverty is learned by touching the flesh of the poor Christ, in the humble, the poor, the sick, in children. ~ Pope Francis

This "Hawking temperature" of a black hole and its "Hawking radiation" (as they came to be called) were truly radical - perhaps the most radical theoretical physics discovery in the second half of the twentieth century. They opened our eyes to profound connections between general relativity (black holes), thermodynamics (the physics of heat) and quantum physics (the creation of particles where before there were none). For example, they led Stephen to prove that a black hole has entropy, which means that somewhere inside or around the black hole there is enormous randomness. He deduced that the amount of entropy (the logarithm of the hole's amount of randomness) is proportional to the hole's surface area. His formula for the entropy is engraved on Stephen's memorial stone at Gonville and Caius College in Cambridge, where he worked.
For the past forty-five years, Stephen and hundreds of other physicists have struggled to understand the precise nature of a black hole's randomness. It is a question that keeps on generating new insights about the marriage of quantum theory with general relativity - that is, about the ill-understood laws of quantum gravity. ~ Stephen Hawking

Classically, cosmetics companies will take highly theoretical, textbookish information about the way that cells work - the components at a molecular level or the behavior of cells in a glass dish - and then pretend it's the same as the ultimate issue of whether something makes you look nice. "This molecular component," they say, with a flourish, "is crucial for collagen formation." And that will be perfectly true (along with many other amino acids which are used by your body to assemble protein in joints, skin, and everywhere else), but there is no reason to believe that anyone is deficient in it or that smearing it on your face will make any difference to your appearance. In general, you don't absorb things very well through your skin, because its purpose is to be relatively impermeable. When you sit in a bath of baked beans for charity, you do not get fat, nor do you start farting. ~ Ben Goldacre

After some minor pieces of theoretical study that I worked on, a student in my statistical mechanics class brought to my attention a problem in polyelectrolytes. ~ Rudolph A. Marcus

Willard Gibbs did for statistical mechanics and for thermodynamics what Laplace did for celestial mechanics and Maxwell did for electrodynamics, namely, made his field a well-nigh finished theoretical structure. ~ Robert Andrews Millikan

Well did you call the hypothetical hardware store and buy a theoretical chainsaw?
Pam to Jessica, True Blood ~ Alan Ball

The hypothesis I wish to advance is thatthe language of morality is ingrave disorder ... What we possess, if this is true, are the fragments of a conceptual scheme, parts of which now lack those contexts from which their significance derived. We possess indeed simulacra of morality, we continue to use many of the key expressions. But we have
very largely if not entirely
lost our comprehension, both theoretical and practical, of morality. ~ Alasdair MacIntyre

One cannot do justice to Marx without recognizing his sincerity. His open-mindedness, his sense of facts, his distrust of verbiage, and especially of moralizing verbiage, made him one of the world's most influential fighters against hypocrisy and pharisaism. He had a burning desire to help the oppressed, and was fully conscious of the need for proving himself in deeds, and not only in words. His main talents being theoretical, he devoted immense labour to forging what he believed to be scientific weapons for the fight to improve the lot of the vast majority of men. His sincerity in his search for truth and his intellectual honesty distinguish him, I believe, from many of his followers (although unfortunately he did not altogether escape the corrupting influence of an upbringing in the atmosphere of Hegelian dialectics, described by Schopenhauer as 'destructive of all intelligence'). Marx's interest in social science and social philosophy was fundamentally a practical interest. He saw in knowledge a means of promoting the progress of man. ~ Karl Popper

Every theoretical explanation is a reduction of intuition. ~ Peter Hoeg

While much of postmodernist analysis should be credited with theoretical imagination, as well as talent for capturing something of the Zeitgeist, this type of analysis nonetheless misses some crucial facts about consumption: that consumption is vitally linked to production; consumption is anchored in concrete relations; and the driving force in consumption is individual interest, as encouraged and often shaped by profit interests. ~ Richard Swedberg

I don't have a favorite cooking tool. In the kitchen, I always have my pencil and notebook in my hand. I cook more theoretically than I do practically. My job is creative, and in the kitchen, the biggest part of my creativity is theoretical. The pencil has a symbolic meaning for me. The type of person who carries a pencil around is the type of person who's open to change. Someone who walks around with a pen isn't; he's the opposite. ~ Ferran Adria

If the experimental physicist has already done a great deal of work in this field, nevertheless the theoretical physicist has still hardly begun to evaluate the experimental material which may lead him to conclusions about the structure of the atom. ~ Johannes Stark

The kissed surprised him because it had been so long since he'd kissed anyone but Elspeth. It surprised Valentina because she had hardly ever kissed anyone that way - to her, kissing had always been more theoretical than physical. Afterwards she stood with her eyes closed, lips parted, face tilted. Robert thought, She's going to break my heart and I'm going to let her. ~ Audrey Niffenegger

Today, we know that time travel need not be confined to myths, science fiction, Hollywood movies, or even speculation by theoretical physicists. Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object. This means that if you were to travel into outer space and return, moving close to light speed, you could travel thousands of years into the Earth's future. ~ Clifford A. Pickover

One thing most of us agree on is that the universe exists (people who deny that usually follow some trade other than science), so if some theoretical particle interaction would lead ultimately to the nonexistence of the universe, then you can save a lot of electricity by not trying to demonstrate it. ~ Joe Haldeman

The ideology and philosophy of neo-Darwinism which is sold by its adepts as a scientific theoretical foundation of biology seriously hampers the development of science and hides from students the field's real problems. ~ Vladimir L. Voeikov

The desire to serve the common good must without fail be a requisite of the soul, a necessity for personal happiness; if it issuesnot from there, but from theoretical or other considerations, it is not at all the same thing. ~ Anton Chekhov

It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo drums, the introducer never seems to find it necessary to mention that I also do theoretical physics. ~ Richard P. Feynman

The young were always theoretical; only the middle-aged could realize the deadliness of principles. To subdue one's self to one's own ends might be dangerous, but to subdue one's self to other people's ends was dust and ashes. Yet there were those, still more unhappy, who envied even the ashy saltiness of those dead sea apples. ~ Dorothy L. Sayers

And then there is Pythagoras. The legend is that the founder of theoretical mathematics was so outraged when one of his students, the haplessly gifted Hippasus, discovered irrational numbers21 that he sent the poor fellow out on a raft to drown, initiating a venerable tradition of professors mistreating their graduate students. ~ Rebecca Goldstein

I often notice how students can gain the capacity to use certain critical methodologies through engaging with very different texts - how a graphic novel about gentrification and an anthology about Hurricane Katrina and a journalistic account of war profiteering might all lead to very similar classroom conversations and critical engagement. I'm particularly interested in this when teaching law students who often resist reading interdisciplinary materials or materials they interpret as too theoretical. ~ Dean Spade

Much theoretical work, of course, focuses on existing economic institutions. The theorist wants to explain or forecast the economic or social outcomes that these institutions generate. ~ Eric Maskin

Theoretical and experimental physicists are now studying nothing at all-the vacuum. But that nothingness contains all of being. ~ Heinz Pagels

But any explanation which analyzes one sector to the exclusion of all others is unbalanced, and thus wrong. The socio-economic, spiritual and psychological explanations look at the same phenomena from different aspects, and the very task of a theoretical analysis is to see how these different aspects are interrelated, and how they interact. ~ Erich Fromm

I think our science is a marvelous tool. Of course it has its politics, its failings, its mistakes, like all other human endeavors, but I think the methodology of our science - using it to postulate and to use the proper approach of creating falsifiable hypotheses and then testing them to see if they ring true, and then progressing by finding the anomalies to our theoretical structure, and then improving our theoretical structure to take care and test the anomalies - is the way to go, because that helps us discover what the universe.is all about and our relationship to it. ~ Edgar Mitchell

The function of the well-intentioned individual, acting in isolation, is to formulate or disseminate theoretical truths. The function of the well-intentioned individuals in association is to live in accordance with those truths, to demonstrate what happens when theory is translated into practice, to create small-scale working models of the better form of society to which the speculative idealist looks forward. ~ Aldous Huxley

I recognize that many physicists are smarter than I am-most of them theoretical physicists. A lot of smart people have gone into theoretical physics, therefore the field is extremely competitive. I console myself with the thought that although they may be smarter and may be deeper thinkers than I am, I have broader interests than they have. ~ Linus Pauling

Evolutionary dynamics has no need of vast abstract spaces, like all the possible viable animals, DNA sequences, sets of proteins, or biological laws. Better, as the theoretical biologist Stuart A. Kauffman proposes, to think of evolutionary dynamics as the exploration in time by the biosphere of what can happen next: the "adjacent possible." The same goes for the evolution of technologies, economies, and societies. ~ Anonymous

I mean, of course that's a theoretical question, and we don't know what it would be for, and we don't know how many numbers there are. I am against American combat troops being in Syria and Iraq. ~ Hillary Clinton

Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea. ~ Richard P. Feynman

The actors make the film. They're the ones that take this theoretical movie that's in your head and make it real. The success of a film is entirely on their shoulders. I admire them, because acting is such a difficult thing to do, and I personally can't understand it. ~ Alejandro Gonzalez Inarritu

Interstiality is a theme that is simultaneously genuinely interesting and potentially quite useful, and also a terrible cliché, so if you're going to use it, it helps to be at least respectfully skeptical about the wilder claims of its theoretical partisans, I think. ~ China Mieville

In one of my favorite scenes from one of my favorite movies, Amadeus, Salieri looks with wide-eyed astonishment at a manuscript of Mozart's and says, "Displace one note and there would be diminishment. Displace one phrase and the structure would fall."

In this, Salieri captured the essence of perfection. His two sentences define precisely what we mean by perfection in many contexts, including theoretical physics. You might say it's a perfect definition.

A theory begins to be perfect if any change makes it worse. That's Salieri's first sentence, translated from music to physics. And it's right on point. But the real genius comes with Salieri's second sentence. A theory becomes perfectly perfect if it's impossible to change it significantly without ruining it entirely-that is, if changing the theory significantly reduces it to nonsense. ~ Frank Wilczek

It has long been my personal view that the separation of practical and theoretical work is artificial and injurious. Much of the practical work done in computing, both in software and in hardware design, is unsound and clumsy because the people who do it have not any clear understanding of the fundamental design principles of their work. Most of the abstract mathematical and theoretical work is sterile because it has no point of contact with real computing. ~ Christopher Strachey

In choosing to be a Psychology major, I decided to learn for the joy of learning for the first time in my life. I'd always been fascinated by human nature. What makes us act the way we do? Why do we make the same mistakes over and over? But I guess my interest is purely theoretical. I'm a Psychology major
who has no desire to work with people. This was poor planning on my part, I suppose. My parents definitely think so. But choosing passion over practicality seemed so honorable when I was a first-year student and graduation seemed so very, very far away . . .

But now, a semester away from unemployment, I realize how much better off those Engineering students really are. Sure, they're boring conversationalists that make you want to kill yourself because every story begins, "The other day? In the lab?" But people become a whole helluva lot more interesting when they're pulling down six figures, don't they? If I'm going to drag my friends out to my cardboard box, the pressure's on to provide some pretty goddamned sparkling conversation once they get there. And even with all my noble knowledge for knowledge's sake, I'm not sure I can. ~ Megan McCafferty

The progress of science depends much less upon either theoretical considerations or systematic investigation than is commonly believed, but rather on the transmittal of reliable information, gained by chance or insight, from one set of men to their successors. ~ Gene Wolfe

The ridge of the Lammer-muir hills... consists of primary micaceous schistus, and extends from St Abb's head westward... The sea-coast affords a transverse section of this alpine tract at its eastern extremity, and exhibits the change from the primary to the secondary strata... Dr HUTTON wished particularly to examine the latter of these, and on this occasion Sir JAMES HALL and I had the pleasure to accompany him. We sailed in a boat from Dunglass ... We made for a high rocky point or head-land, the SICCAR ... On landing at this point, we found that we actually trode [sic] on the primeval rock... It is here a micaceous schistus, in beds nearly vertical, highly indurated, and stretching from S.E. to N. W. The surface of this rock... has thin covering of red horizontal sandstone laid over it, ... Here, therefore, the immediate contact of the two rocks is not only visible, but is curiously dissected and laid open by the action of the waves... On us who saw these phenomena for the first time, the impression will not easily be forgotten. The palpable evidence presented to us, of one of the most extraordinary and important facts in the natural history of the earth, gave a reality and substance to those theoretical speculations, which, however probable had never till now been directly authenticated by the testimony of the senses... What clearer evidence could we have had of the different formation of these rocks, and of the long interval which separated their formation, had we actua ~ John Playfair

...I stand looking at the aircraft, trying in vain to remember all the theoretical lore which i was supposed to have absorbed in school. The effort is discouraging. ~ Ernest K. Gann

Scientific Religion is compatible with Science and in fact, they enrich each other. That's because scientific religion is simply the realization of divinity within one's heart. Therefore, Science and Scientific Religion smoothen each other's path of progress. While on the contrary, far from being compatible with Science, Theoretical Religion consistently tries to impede the development of human society. Moreover, being rigidly based on bookish doctrines, it keeps making efforts to drag the human society back to the Stone Age.
I am afraid, if you don't act now, the relentless battle between Theoretical Religions will turn this beautiful planet which we call home, into a barren wasteland. ~ Abhijit Naskar

Of course you will, Hodges thinks. You might think you know what you're risking, but you don't. When you're seventeen, the future is strictly theoretical. ~ Stephen King

Unrequited love was typically my favorite kind of love. The non-reciprocal nature of it appealed to me in much the same way boy bands appealed to me; it was theoretical love because it was untested - hopeless in its one-sidedness, yet tragically inspiring. ~ Penny Reid

It would be an advance if the secular theoretical establishment, and the contemporary enlightened culture which it dominates, could wean itself of the materialism and Darwinism of the gaps ~ Thomas Nagel

I have confronted theoretical positions whose protagonists claim that what I take to be historically produced characteristics of what is specifically modern are in fact the timelessly necessary characteristics of all and any moral judgment, of all and any selfhood. ~ Alasdair MacIntyre

One important idea is that science is a means whereby learning is achieved, not by mere theoretical speculation on the one hand, nor by the undirected accumulation of practical facts on the other, but rather by a motivated iteration between theory and practice. ~ George E.P. Box

On a level, they might be perfect for one another, but it's a theoretical perfection only, compromised by timing. Their bests passed one another on the way to here, and now exist epochs apart. ~ Billy O'Callaghan

No physicist started out impatient with common-sense notions, eager to replace them with some mathematical abstraction that could be understood only by rarified theoretical physics. Instead, they began, as we all do, with comfortable, standard, common-sense notions. The trouble is that Nature does not comply. If we no longer insist on our notions of how Nature ought to behave, but instead stand before Nature with an open and receptive mind, we find that common sense often doesn't work. Why not? Because our notions, both hereditary and learned, of how Nature works were forged in the millions of years our ancestors were hunters and gatherers. In this case common sense is a faithless guide because no hunter-gatherer's life ever depended on understanding time-variable electric and magnetic fields. There were no evolutionary penalties for ignorance of Maxwell's equations. In our time it's different. ~ Carl Sagan

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

It was during this period of work that Varda began to conceive a more theoretical approach to her art. She says, "[My work] deals with this question, 'What is cinema?' through how I found specific cinematic ways of telling what I was telling. I could have told you the same things that are in the film by just talking to you for six hours. But instead I found shapes" (Warwick). To give a name to her very particular and personal search for a cinematic language, Varda coined the term cinécriture. As she explains to Jean Decock: "When you write a musical score, someone else can play it, it's a sign. When an architect draws up a detailed floor plan, anyone can build his house. But for me, there's no way I could write a scenario that someone else could shoot, since the scenario doesn't represent the writing of the film." Later she would clarify, "The cutting, the movement, the points-of-view, the rhythm of filming and editing have been felt and considered in the way a writer chooses the depth of meaning of sentences, the type of words, number of adverbs, paragraphs, asides, chapters which advance the story or break its flow, etc. In writing its called style. In the cinema, style is cinécriture." (Varda par Agnès [1994], 14). ~ T. Jefferson Kline

We have forensic psychiatrists who try to draw a line between those who are sick and those who are criminal, and they bend and twist the truth to make it fit into their world of theoretical models. ~ Jo Nesbo

Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures and results in our classical domain. ~ John Stewart Bell

Our hypotheses are initially rooted in theoretical consistency and elegance, but ... ultimatel y it is experiment not rigid belief that determines what is correct. ~ Lisa Randall

I don't shy away from saying that the single most developed tradition of critical thought devoted to the study of capitalism was initiated by Karl Marx. His work was built on that of many people who preceded him. It does not offer the only set of solutions to our problems; it has its own shortcomings and failures. But if you want to think critically about capitalism, sooner of later you are going to have to encounter the theoretical traditions of Marxism, because it is the most developed and draws from contributions made from every country on Earth, from a thousand struggles against business and governments supporting capitalism. It's a repository, a rich resource that ought to be made use of by anyone who wants to have a balanced perspective when it comes to dealing with the real problems. ~ Richard Wolff

The panorama-city is a 'theoretical' (that is, visual) simulacrum, in short a picture, whose condition of possibility is an oblivion and a misunderstanding of practices. ~ Michel De Certeau

A fair and generous woman is (at best) respected, but seldom loved. ~ Shulamith Firestone

Medicine is the science by which we learn the various states of the human body in health and when not in health, and the means by which health is likely to be lost and, when lost, is likely to be restored back to health. In other words, it is the art whereby health is conserved and the art whereby it is restored after being lost. While some divide medicine into a theoretical and a practical [applied] science, others may assume that it is only theoretical because they see it as a pure science. But, in truth, every science has both a theoretical and a practical side. ~ Avicenna

A second possible approach to general systems theory is through the arrangement of theoretical systems and constructs in a hierarchy of complexity, roughly corresponding to the complexity of the "individuals" of the various empirical fields ... leading towards a "system of systems." ... I suggest below a possible arrangement of "levels" of theoretical discourse ... (vi) ... the "animal" level, characterized by increased mobility, teleological behavior and self-awareness ... ~ Kenneth E. Boulding

Einstein would be one of the greatest theoretical physicists of all time even if he had not written a single line on relativity. ~ Max Born

Om Schooled is the perfect manual for anyone who wants to start teaching yoga to kids. This is not just a theoretical book - it is a step-by-step manual. Sarah Herrington shares the wisdom she has gained from her day-to-day experiences, for many years, teaching all ages of children yoga in the New York School system. ~ Sharon Gannon

it is important to stress that history is always constructed, not absolute or unchallangeable. Histories are stories about the past, and reconstructing the past ill involve elements of mythologising from the cultural, political and theoretical stances of both the historian and the informants. ~ John O'Toole

Knowledge has the form of a tree, and since metaphysics is the most fundamental one of the theoretical disciplines, it represents the roots of the tree. ~ Gonzalo Rodriguez-Pereyra

The problem is, most people believe that real science is too difficult and complicated for them to understand. But I don't think this is the case. To do research on the fundamental laws that govern the universe would require a commitment of time that most people don't have; the world would soon grind to a halt if we all tried to do theoretical physics. But most people can understand and appreciate the basic ideas if they are presented in a clear way without equations, which I believe is possible and which is something I have enjoyed trying to do throughout my life. ~ Stephen Hawking

I cook more theoretically than I do practically. My job is creative, and in the kitchen, the biggest part of my creativity is theoretical. ~ Ferran Adria

The earlier, more analytic impulse was to use very rational but kind of absurd techniques or tendencies - mapping, charting, and architecture - to try and make sense of who I was in my time and space and political environment. But there's only so much truth to a theoretical understanding of something. ~ Julie Mehretu

The pervasion of image has so deeply altered our very relationships to ourselves that even men have become objects
if never erotic objects. ~ Shulamith Firestone

They asked for Plato's assistance. He told them: "You hated wisdom and ran away from geometry, therefore God has afflicted you a punishment, for wisdom and philosophical knowledge have a high rank with God." ... The plague was lifted and they ceased to defame the branches of theoretical knowledge. ~ Mulla Sadra

Besides this I place another equally obvious confirmation of my view that opera is based on the same principles as our Alexandrian culture. Opera is the birth of the theoretical man, the critical layman, not of the artist: one of the most surprising facts in the history of all the arts. It was the demand of throughly unmusical hearers that before everything else the words must be understood, so that according to them a rebirth of music is to be expected only when some mode of singing has been discovered in which textword lords it over counterpoint like master over servant: For the words, it is argued, are as much nobler than the accompanying harmonic system as the soul is nobler than the body. ~ Friedrich Nietzsche

Philosophers of science have repeatedly demonstrated that more than one theoretical construction can always be placed upon a given collection of data. ~ Thomas Kuhn

Human potential is the ability of a person or humanity to put their theoretical abilities into practice ~ Sunday Adelaja

For in the theoretical field bourgeois economics no longer engages in blithe and joyous fights. ~ Rudolf Hilferding

The slogan 'Never Again!' that emerged after the Holocaust implies that the Holocaust has a universal moral meaning, which, if properly learned, can provide at least a theoretical prophylactic against its repetition against anyone. ~ David Novak

Seduced by the spectacular theoretical and practical successes of the objective sciences into thinking that the methods and criteria of those sciences were the only means to truth, philosophers sought to apply those same methods and criteria to questions relating to the meaning of life and the values that give meaning to life. Philosophy, especially the Analytical species prevalent in the English-speaking world, was broken up into specialized disciplines and fragmented into particular problems, all swayed and impregnated by scientism, reductionism, and relativism. All questions of meaning and value were consigned to the rubbish heap of 'metaphysical nonsense'. ~ D.R. Khashaba

There is no escaping the fact, however, that social science research on the distribution of wealth was for a long time based on a relatively limited set of firmly established facts together with a wide variety of purely theoretical speculations. ~ Thomas Piketty

When you work on something that combines both the spectacular and the relatable, the hyperreal and the real, it suddenly can become supernatural. The hypothetical and the theoretical can become literal. ~ J.J. Abrams

Clearly, one does not have to give up being an academic, retreat from rigorous research, or renounce the importance of specialization in order to address major social issues. I don't think you give up theoretical rigor by writing in a way that addresses major social concerns and is at the same time accessible to wider informed general audiences. ~ Henry Giroux

The work requires a moderately large investment in technological and theoretical developments and long periods of time to carry them out, without the pressure to achieve quick or short term results. ~ Aaron Klug

Theology, however implausible many of its truth claims, is one of the most ambitious theoretical arenas left in an increasingly specialized world ~ Terry Eagleton

To narrow natural rights to such neat slogans as "liberty, equality, fraternity" or "life, liberty, property," . . . was to ignore the complexity of public affairs and to leave out of consideration most moral relationships. . . .

Burke appealed back beyond Locke to an idea of community far warmer and richer than Locke's or Hobbes's aggregation of individuals. The true compact of society, Burke told his countrymen, is eternal: it joins the dead, the living, and the unborn. We all participate in this spiritual and social partnership, because it is ordained of God. In defense of social harmony, Burke appealed to what Locke had ignored: the love of neighbor and the sense of duty. By the time of the French Revolution, Locke's argument in the Second Treatise already had become insufficient to sustain a social order. . . .

The Constitution is not a theoretical document at all, and the influence of Locke upon it is negligible, although Locke's phrases, at least, crept into the Declaration of Independence, despite Jefferson's awkwardness about confessing the source of "life, liberty, and the pursuit of happiness."

If we turn to the books read and quoted by American leaders near the end of the eighteenth century, we discover that Locke was but one philosopher and political advocate among the many writers whose influence they acknowledged. . . .

Even Jefferson, though he had read Locke, cites in his Commonplace Book such juridical authorities ~ Russell Kirk

The implications of our obstacle are theoretical
they exist in the past and the future. We live in the moment. And the more we embrace that, the easier the obstacle will be to face and move. You can take the trouble you're dealing with and use it as an opportunity to focus on the present moment. To ignore the totality of your situation and learn to be content with what happens, as it happens. To have no "way" that the future needs to be to confirm your predictions, because you didn't make any. To let each new moment be a refresh wiping clear what came before and what others were hoping would come next. ~ Ryan Holiday

Let's just say that drama became something very real to me that day, she said. It ceased to be theoretical, was no longer an internal structure in which she could hide and look out on the wold. In a sense, her work had jumped out of a bush and attacked her.

I said it seemed to me that at a certain point a lot of people felt that, not about work but about life itself. ~ Rachel Cusk
