Scientific Theory Quotes

It is sometimes said that we should never believe a scientific theory until it is verified by experiment. But a famous astronomer has also stated that we should never believe an observation until it is confirmed by a theory. ~ Joao Magueijo

Journalism only tells us what men are doing; it is fiction that tells us what they are thinking, and still more what they are feeling. If a new scientific theory finds the soul of a man in his dreams, at least it ought not to leave out his day-dreams. And all fiction is only a diary of day-dreams instead of days. And this profound preoccupation of men's minds with certain things always eventually has an effect even on the external expression of the age. ~ Gilbert K. Chesterton

I have come to the conclusion that Darwinism is not a testable scientific theory, but a metaphysical research programme ... ~ Karl Popper

The hold of the evolutionary paradigm is so powerful that an idea which is more like a principle of medieval astrology than a serious twentieth century scientific theory has become a reality for evolutionary biologists. ~ Michael Denton

My colleague Sen. Rick Santorum, Pennsylvania Republican, erroneously suggested that I support the teaching of intelligent design as an alternative to biological evolution. That simply is not true. ... Unlike biological evolution, intelligent design is not a genuine scientific theory and, therefore, has no place in the curriculum of our nation's public school science classes. ~ Edward Kennedy

It is more important to have beauty in one's equations than to have them fit experiment. ~ Paul Dirac

Perhaps, the highest pleasure in art is identical with the highest pleasure in scientific theory. The emotion which accompanies the clear recognition of unity in a complex seems so similar in art and in science that it is difficult not to suppose that they are psychologically the same. It is, as it were, the final stage of both a processes.This unity-emotion in science supervenes upon a process of pure mechanical reasoning; in art it supervenes upon a process of which emotion has all along been an essential concomitant. ~ Roger Fry

The greatest discoveries of science have always been those that forced us to rethink our beliefs about the universe and our place in it. ~ Robert L. Park

A mere inference or theory must give way to a truth revealed; but a scientific truth must be maintained, however contradictory it may appear to the most cherished doctrines of religion. ~ David Brewster

Europe is so well gardened that it resembles a work of art, a scientific theory, a neat metaphysical system. Man has re-created Europe in his own image. ~ Aldous Huxley

The Theory of Relativity confers an absolute meaning on a magnitude which in classical theory has only a relative significance: the velocity of light. The velocity of light is to the Theory of Relativity as the elementary quantum of action is to the Quantum Theory: it is its absolute core. ~ Max Planck

Here is Thomas Kuhn, the philosopher of science, describing the way scientists react when their pet theories are unraveling: "What scientists never do when confronted by even severe and prolonged anomalies," Kuhn wrote, " ... . [is] renounce the paradigm that led them into crisis." Instead, he concluded, "A scientific theory is declared invalid only if an alternate candidate is available to take its place." That is, scientific theories very seldom collapse under the weight of their own inadequacy. They topple only when a new and seemingly better belief turns up to replace it. ~ Kathryn Schulz

My own reasons for favouring talk of natural kinds is just that I believe the best accounts of the success of scientific theories presupposes the existence of natural kinds. ~ Hilary Kornblith

The evolution of higher and of lower forms of life is as well and as soundly established as the eternal hills. It has long since ceased to be a theory; it is a law of Nature as universal in living things as is the law of gravitation in material things and in the motions of the heavenly spheres. ~ Henry Fairfield Osborn

First, the idea of the multiverse is essentially the fantasy of preserving perfect information. One of the hard things to deal with in life is the fact that you destroy potential information whenever you make a decision. You could even say that's essentially what regret is: a profound problem of incomplete information. If you select one thing on a diner's menu, you can't know what it would have been like to taste other things on it, right then, right there. When you marry one person, you give up the possibility of knowing what it would have been like to have married any number of others. But if the multiverse exists, you can at least imagine there's another version of you who's eating that other thing you thought about ordering, or who's married to that other man you only went on two dates with. Even if you'll never see all the information for yourself, at least you'll be able to tell yourself that it's there.

'The second reason the multiverse seems like such a neat idea is that it gives human beings just an incredible amount of agency, which they can exercise with the least effort. Why, Carson here created an entire alternate universe when he ordered hash browns on the side of his French toast instead of bacon - '

'Ah, I should have gotten bacon, how could I forget,' Carson said, and attempted to hail the waitress.

'But the history of science shows that any theory that covertly panders to the human ego like that, that puts humans at the cente ~ Dexter Palmer

Any strategy that attempts to reinforce faith by undermining science is also doomed to failure. Showing that some scientific theory is wrong will not prove that the religious alternative is correct by default. When the sun was shown not to be the center of the universe, as Copernicus had proposed, the Earth was not moved back to that singular position in the cosmos. If Darwinian evolution is proved wrong, biologists will not develop a new theory based on the hypothesis that each species was created separately by God 6,000years ago. ~ Victor J. Stenger

No scientific theory touches on the mysteries that the religious tradition addresses. A man asking why his days are short and full of suffering is not disposed to turn to algebraic quantum field theory for the answer. The answers that prominent scientific figures have offered are remarkable in their shallowness. ~ David Berlinski

This theory [the oxygen theory] is not as I have heard it described, that of the French chemists, it is mine (elle est la mienne); it is a property which I claim from my contemporaries and from posterity. ~ Antoine Lavoisier

It would seem that the scientific revolution involved not just a progressive transformation of scientific theory, but also a transformation in what were considered to be the observable facts! ~ Alan F. Chalmers

Even a scientist is a human being. So it is natural for him, like others, to hate the things he cannot explain. It is a common illusion to believe that what we know today is all we ever can know. Nothing is more vulnerable than scientific theory, which is an ephemeral attempt to explain facts and not an everlasting truth in itself. ~ C. G. Jung

What is then the central idea of transcendental philosophy? It is to construe each object of science as the focus of a synthesis of phenomena rather than as a thing in itself. And it is to accept accordingly that the very possibility of such objects depends on the connecting structures provided in advance by the procedures used in our research activities. Thus something is objective if it results from a universal and necessary mode of connection of phenomena. In other words, something is objective if it holds true for any (human) active subject, not if it concerns intrinsic properties of autonomous entities. (...)

From a transcendental standpoint, the structure of a scientific theory is nothing less than the frame of procedural rationalities that underpin a certain research practice (and that, conversely, were constrained by the resistances arising from the enaction of this practice). ~ Michel Bitbol

Well, it [evolution] is a theory, it is a scientific theory only, and it has in recent years been challenged in the world of science and is not yet believed in the scientific community to be as infallible as it once was believed. But if it was going to be taught in the schools, then I think that also the biblical theory of creation, which is not a theory but the biblical story of creation, should also be taught. ~ Ronald Reagan

Darwin's theory was received in Russia with profound sympathy. While in Western Europe it met firmly established old traditions which it had first to overcome, in Russia its appearance coincided with the awakening of our society after the Crimean War and here it immediately received the status of full citizenship and ever since has enjoyed widespread popularity. ~ Vladimir Onufrievich Kovalevskiy

A universe with a God would look quite different from a universe without one. A physics, a biology where there is a God is bound to look different. So the most basic claims of religion are scientific. Religion is a scientific theory. ~ Richard Dawkins

I venture to define science as a series of interconnected concepts and conceptual schemes arising from experiment and observation and fruitful of further experiments and observations. The test of a scientific theory is, I suggest, its fruitfulness. ~ James Bryant Conant

About seven years later I was given a book about the periodic table of the elements. For the first time I saw the elegance of scientific theory and its predictive power. ~ Sidney Altman

Theories, for me, are just about freeing your mind. It doesn't mean the theory is going to work like a scientific theory works. It's about freeing your mind and making you think a different way. ~ Steve Martin

One does not ask whether a scientific theory is true, but only whether it is convenient. ~ Henri Poincare

Class analysis can thus function not simply as part of scientific theory of interests and conflicts, but of an emancipatory theory of alternatives and social justice as well. Even if socialism is off the historical agenda, the idea of countering the exploitative logic of capitalism is not. ~ Erik Olin Wright

The proper measure of a philosophical system or a scientific theory is not the degree to which it anticipated modern thought, but its degree of success in treating the philosophical and scientific problems of its own day. ~ Steven Weinberg

It is an irony of history that the first and greatest success of scientists in persuading governments of the indispensability of modern scientific theory to society was in the war against fascism. It is an even greater and more tragic irony that it was anti-fascist scientists who convinced the American government of the feasibility and necessity of manufacturing nuclear arms, which were then constructed by an international team of largely anti-fascist scientists. ~ Eric Hobsbawm

Art is a creation of a higher order than a copy of nature which is governed by chance ... By the elimination of all muddy colors, by the exclusive use of optical mixture of pure colors, by a methodical divisionism and a strict observation of the scientific theory of colors, the neo-impressionists insures a maximum of luminosity, of color intensity, and of harmony- a result that has never yet been obtained. ~ Paul Signac

The scientific theory I like best is that the rings of Saturn are composed entirely of lost airline luggage. ~ Mark Russell

I do agree that the science is not settled on this. The idea that we would put American's economy at jeopardy based on scientific theory that's not settled yet, to me is just nonsense. Just because you have a group of scientists that stood up and said, this is the fact. Galileo got outvoted for a spell. But the fact is, to put America's economic future in jeopardy, asking us to cut back in areas that would have monstrous economic impact on this country, is not good economics, and I will suggest to you is not necessarily good science. ~ Rick Perry

Then you would have acted to change history, but you would have replaced one history with another. You would not be able to know what past version of history you would have altered, because that history would never have happened. Nor would you be able to know what you had done in the past, or that you had done anything at all in the past, or that you had even been to the past. You would not be able to compare histories in your mind; if you entered the causality violation device knowing this, then you would realize that you would be trading one set of memories for another, and that there would never be any evidence, in your mind or in the world, that you had done this. ~ Dexter Palmer

I was trained as a philosopher never to put philosophers and their ideas into historical contexts, since historical context has nothing to do with the validity of the philosopher's positions. I agree that assessing validity and contextualizing historically are two entirely distinct matters and not to be confused with one another. And yet that firm distinction doesn't lead me to endorse the usual way in which history of philosophy is presented. ... The philosophers talk across the centuries exclusively to one another, hermetically sealed from any influences derived from non-philosophical discourse. The subject is far more interesting than that.

... When you ask why did some particular question occur to a scientist or philosopher for the first time, or why did this particular approach seem natural, then your questions concern the context of discovery. When you ask whether the argument the philosopher puts forth to answer that question is sound, or whether the evidence justifies the scientific theory proposed, then you've entered the context of justification. Considerations of history, sociology, anthropology, and psychology are relevant to the context of discovery, but not to justification. You have to keep them straight.... ...(T)he assessment of those intuitions in terms of the argument's soundness isn't accomplished by work done in the context of discovery. And conversely, one doesn't diminish a philosopher's achievement, and doesn't undermine its soundness, by s ~ Rebecca Goldstein

Scientific theory is a contrived foothold in the chaos of living phenomena. ~ Wilhelm Reich

For Bohr the theory came first, then the philosophical position, the interpretation constructed to make sense of what the theory says about reality. Einstein knew that it was dangerous to build a philosophical worldview on the foundation of any scientific theory. If the theory is found wanting in the light of new experimental evidence, then the philosophical position it supports collapses with it. 'it is basic for physics that one assumes a real world existing independently from any act of perception', said Einstein. 'But this we do not know'. ~ Manjit Kumar

A new scientific theory is seldom stated with such clarity by its original author, and usually takes many years to creep into public conciousness. ~ John Ziman

No scientific theory achieves public acceptance until it has been thoroughly discredited. ~ Douglas Yates

The method of science depends on our attempts to describe the world with simple theories: theories that are complex may become untestable, even if they happen to be true. Science may be described as the art of systematic over-simplification-the art of discerning what we may with advantage omit. ~ Karl Popper

I think a strong claim can be made that the process of scientific discovery may be regarded as a form of art. This is best seen in the theoretical aspects of Physical Science. The mathematical theorist builds up on certain assumptions and according to well understood logical rules, step by step, a stately edifice, while his imaginative power brings out clearly the hidden relations between its parts. A well constructed theory is in some respects undoubtedly an artistic production. A fine example is the famous Kinetic Theory of Maxwell ... The theory of relativity by Einstein, quite apart from any question of its validity, cannot but be regarded as a magnificent work of art. ~ Ernest Rutherford

. . .a scientific theory is just a mathematical model we make to describe our observations: it exists only in our minds. So it is meaningless to ask: which is real, "real" or "imaginary" time? It is simply a matter of which is the more useful description. ~ Stephen Hawking

My provocative statement is that we desperately need a serious, scientific theory of cities and scientific theory means quantifiable, relying on underlying generic principles that can be made in a - put into a predictive framework. That's the quest. ~ Geoffrey West

A scientific theory is a tool and not a creed. ~ Joseph John Thomson

Theories cannot claim to be indestructible. They are only the plough which the ploughman uses to draw his furrow and which he has every right to discard for another one, of improved design, after the harvest. To be this ploughman, to see my labours result in the furtherance of scientific progress, was the height of my ambition, and now the Swedish Academy of Sciences has come, at this harvest, to add the most brilliant of crowns. ~ Paul Sabatier

I will say to you what the scientists say about the small particles in the universe: I can't show you where they are, I can only show you where they were. ~ Anne Fortier

Scientific theory and its application to the growing needs of mankind advance hand in hand. ~ Cargill Gilston Knott

Claims that cannot be tested, assertions immune to disproof are veridically worthless, whatever value the may have in inspiring us or in exciting our sense of wonder. ~ Carl Sagan

We don't regard any scientific theory as the absolute truth. ~ Kenneth R. Miller

If we have abdicated our birthright to scientific progress, we have done so by moving the debate into the realm of political and cultural argument, where we all feel more confident, because it is there that the Gut rules. Held to the standards of that context, any scientific theory is turned into mere opinion. Scientific fact is no more immutable than a polling sample. ~ Charles P. Pierce

A good simulation, be it a religious myth or scientific theory, gives us a sense of mastery over experience. To represent something symbolically, as we do when we speak or write, is somehow to capture it, thus making it one's own. But with this appropriation comes the realization that we have denied the immediacy of reality and that in creating a substitute we have but spun another thread in the web of our grand illusion. ~ Heinz Pagels

Although the formulations of science now offer the most advanced knowledge of nature, men continue to use obsolete forms of thought long discarded by scientific theory. In so far as these obsolete forms are superfluous for science, the fact that they persist violated the principle of the economy of thought, that characteristic trait of the bourgeois temper. ~ Max Horkheimer

There is no scientific theory that could lead us from a detailed map of every single neuron in someone's brain to a conscious experience. We don't even have the beginnings of a theory whose conclusion would be such a system is conscious. ~ Stuart J. Russell

Asimov's "The Relativity of Wrong":3 When people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together. ~ Eliezer Yudkowsky

A good scientific theory should be explicable to a barmaid. ~ Ernest Rutherford

Our acceptance of an ontology is, I think, similar in principle to our acceptance of a scientific theory, say a system of physics;we adopt, at least insofar as we are reasonable, the simplest conceptual scheme into which the disordered fragments of raw experience can be fitted and arranged. ~ Willard Van Orman Quine

The deepest human intuition is not the immediate grasping of the classical-physics-type character of the external world. It is rather that one's own conscious subjective efforts can influence the experiences that follow. Any conception of nature that makes this deep intuition an illusion is counterintuitive. Any conception of reality that cannot explain how our conscious efforts influence our bodily actions is problematic. What is actually deeply intuitive is the continually reconfirmed fact that our conscious efforts can influence certain kinds of experiential feedback. A putatively rational scientific theory needs at the very least to explain this connection in a rational way to be in line with intuition. ~ Paul Davies

My choice of colors does not rest on any scientific theory, it is based on observation, on feeling, on the experience of my sensibility. ~ Henri Matisse

She knew for a fact that being left-handed automatically made you special.
Marie Curie, Albert Einstein, Linus Pauling, and Albert Schweitzer were all left-handed. Of course, no believable scientific theory could rest on such a small group of people. When Lindsay probed further, however, more proof emerged. Michelangelo, Leonardo da Vinci, M.C. Escher, Mark Twain, Hans Christian Andersen, Lewis Carrol, H.G. Wells, Eudora Welty, and Jessamyn West- all lefties. The lack of women in her research had initially bothered her until she mentioned it to Allegra. "Chalk that up to male chauvinism," she said. "Lots of left-handed women were geniuses. Janis Joplin was. All it means is that the macho-man researchers didn't bother asking. ~ Jo-Ann Mapson

From this point of view the question of the scientific status of Darwinian theory - in the widest sense, the theory of trial and error-elimination - becomes an interesting one. I have come to the conclusion that Darwinism is not a testable scientific theory, but a metaphysical research programme - a possible framework for testable scientific theories. ~ Karl R. Popper

The content of scientific theory itself offers no moral foundation for the personal conduct of life. ~ Albert Einstein

You always have to be worried about something that is considered a so-called 'scientific theory' that fits every scenario. Climate change, as they've defined it, can never be disproved. ~ Ted Cruz

You could consider the idea of the multiverse, and think of it as something like a tree - that is, the universe we live in is one of an uncountable number of branches of possible universes, created by random chance and the decisions of sentient beings. So, for instance, when I rang you up in the morning, there was a possible future universe in which you answered the phone, and another in which you did not, and by answering the phone you put us in one universe and not the other. In that instance the time traveler doesn't just move from the future to the past and back to the future: he moves down one branch of the universe, toward the root that's back at the beginning of time, and back up another branch. ~ Dexter Palmer

The more success the quantum theory has, the sillier it looks. How nonphysicists would scoff if they were able to follow the odd course of developments! ~ Albert Einstein

Capitalism has been fully restored in Yugoslavia, as is well-known, but this capitalism knows how to disguise. Yugoslavia portrays itself as a socialist state, but of a special kind, as the world has never seen it before! The Titoites even boast that their state has nothing in common with the first socialist state which emerged from the socialist October Revolution and which was founded by Lenin and Stalin on the basis of the scientific theory of Marx and Engels. ~ Enver Hoxha

Knowledge of revelation cannot interfere with ordinary knowledge. Likewise, ordinary knowledge cannot interfere with knowledge of revelation. There is no scientific theory which is more favorable to the truth of revelation than any other theory. It is disastrous for theology if theologians prefer one scientific view to others on theological grounds. And it was humiliating for theology when theologians were afraid of new theories for religious reasons, trying to resist them as long as possible, and finally giving in when resistance had become impossible. This ill-conceived resistance of theologians from the time of Galileo to the time of Darwin was one of the causes of the split between religion and secular culture in the past centuries.

The same situation prevails with regard to historical research. Theologians need not be afraid of any historical conjecture, for revealed truth lies in a dimension where it can neither be confirmed nor negated by historiography. Therefore, theologians should not prefer some results of historical research to others on theological grounds, and they should not resist results which finally have to be accepted if scientific honesty is not to be destroyed, even if they seem to undermine the knowledge of revelation. Historical investigations should neither comfort nor worry theologians. Knowledge of revelation, although it is mediated primarily through historical events, does not imply factual assertions, and it is therefore not exposed to ~ Paul Tillich

Even if the open windows of science at first make us shiver after the cozy indoor warmth of traditional humanizing myths, in the end the fresh air brings vigor, and the great spaces have a splendor of their own. ~ Bertrand Russell

Faith in the possibility of science, generated antecedently to the development of modern scientific theory, is an unconscious derivative from medieval theology. ~ Alfred North Whitehead

Historically speaking all - or very nearly all - scientific theories originate from myths. ~ Karl Popper

once it has achieved the status of paradigm, a scientific theory is declared invalid only if an alternate candidate is available to take its place. ~ Thomas S. Kuhn

Any attempt to dismiss a phenomenon that is not understood merely by explaining it as hallucination becomes irrelevant when a coherent scientific theory can be applied. ~ Amit Goswami

A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience. ~ Maurice Allais

Regardless of one's point of view, it's quite easy to see that Darwinism is not in the same league as the hard sciences. For instance, Darwinists will often compare their theory favorably to Einsteinian physics, claiming that Darwinism is just as well established as general relativity. Yet how many physicists, while arguing for the truth of Einsteinian physics, will claim that general relativity is as well established as Darwin's theory? Zero. ~ William A. Dembski

The fundamental core of contemporary Darwinism, the theory of DNA-based reproduction and evolution, is now beyond dispute among scientists. It demonstrates its power every day, contributing crucially to the explanation of planet-sized facts of geology and meteorology, through middle-sized facts of ecology and agronomy, down to the latest microscopic facts of genetic engineering. It unifies all of biology and the history of our planet into a single grand story. Like Gulliver tied down in Lilliput, it is unbudgeable, not because of some one or two huge chains of argument that might–hope against hope–have weak links in them, but because it is securely tied by hundreds of thousands of threads of evidence anchoring it to virtually every other field of knowledge. New discoveries may conceivably lead to dramatic, even 'revolutionary' shifts in the Darwinian theory, but the hope that it will be 'refuted' by some shattering breakthrough is about as reasonable as the hope that we will return to a geocentric vision and discard Copernicus. ~ Daniel C. Dennett

We know that negative reinforcement or punishment works well for behavior that should be eliminated. And we know from feedback theory that the best kind of feedback is descriptive because the client can then make the evaluation. These are valid guidelines but they don't solve some of the subtle issues that can arise in the relationship. ~ Edgar H Schein

If a president can change some laws, can he change ALL laws? Can he change election laws? Can he change discrimination laws? Are there any laws, under your theory, that he actually HAS to enforce? ~ Trey Gowdy

A free-enterprise economy depends only on markets, and according to the most advanced mathematical macroeconomic theory, markets depend only on moods: specifically, the mood of the men in the pinstripes, also known as the Boys on the Street. When the Boys are in a good mood, the market thrives; when they get scared or sullen, it is time for each one of us to look into the retail apple business. ~ Barbara Ehrenreich

The power of such a mountain is so great and yet so subtle that, without compulsion, people are drawn to it from near and far, as if by the force of some invisible magnet…this worshipful or religious attitude is not impressed by scientific facts, like figures of altitude, which are foremost in the mind of modern man. Nor is it motivated by the urge to 'conquer' the mountain. ~ Lama Anagarika Govinda

Jefferson's decision to acquire Louisiana without seeking a constitutional amendment expanded the powers of the executive in ways that would likely have driven Jefferson to distraction had another man been president. Much of his political life, though, had been devoted to the study and the wise exercise of power. He did what had to be done to preserve the possibility of republicanism and progress. Things were neat only in theory. And despite his love of ideas and image of himself, Thomas Jefferson was as much a man of action as he was of theory. Indian ~ Jon Meacham

Scientific understanding is often beautiful, a profoundly aesthetic experience which gives pleasure not unlike the reading of a great poem. ~ Paul Nurse

[Scientific humanism is] the only worldview compatible with science's growing knowledge of the real world and the laws of nature. ~ Edward O. Wilson

The theory of exodus proposes that the most effective way of opposing capitalism and the liberal state is not through direct confrontation but by means of what Paolo Virno has called "engaged withdrawal,"mass defection by those wishing to create new forms of community. One need only glance at the historical record to confirm that most successful forms of popular resistance have taken precisely this form. They have not involved challenging power head on (this usually leads to being slaughtered, or if not, turning into some - often even uglier - variant of the
very thing one first challenged) but from one or another strategy of slipping away from its grasp, from flight, desertion, the founding of new communities. ~ David Graeber

In the library, surrounded by books and computers and scientific journals, I feel like I could grow. ~ Jeremy Bronaugh

[...] and I think (like you, by the way) that theory cannot be fabricated out of the results of observation, but that it can only be invented.
[Letter to Karl Popper; 11 Sep 1939] ~ Albert Einstein

Hi." I caught a flash of his smile as he bent to kiss me. His lips were warm and his kiss was sweet. Gentle. He only deepened the kiss a little while his hand slid into my hair and his other hand curved into the small of my back.

I smiled as he pulled away. "Hi."

"That's better." He cupped my cheek in his hand, his thumb tracing the curve of my cheekbone. "I've missed you since yesterday. Is that weird? Does that make me one of those stalker guys?"

"Only if you follow me home. Cut off a lock of my hair while I sleep. Something like that."

"I thought I'd save that for next weekend." He bent to kiss me again but swerved at the last second to brush his lips against my cheek instead. "I have a theory about you, Emily Parker."

"You do?"

"I do." Another kiss on my cheek, and then his teeth grazed my earlobe, and I shivered. "I don't think you've ever been wooed. Have you?" The words were a low whisper in my ear, and the shiver intensified.

"Wooed?" The word felt strange in my mouth.

"Wooed," he repeated, punctuating the word with a kiss on my other cheek. "Courted. Swept off your feet. Had someone show you how you make him feel."

"I . . . I can't say that I have." That was an understatement.

"Then brace yourself." He straightened up and backed away from me a step or two. "I'm going to woo your ass off. ~ Jen DeLuca

The Chinese have a theory that you pass through boredom into fascination and I think it's true. I would never choose a subject for what it means to me or what I think about it. You've just got to choose a subject - and what you feel about it, what it means, begins to unfold if you just plain choose a subject and do it enough. ~ Diane Arbus

I read one psychologist's theory that said, "Never strike a child in your anger." When could I strike him? When he is kissing me on my birthday? When he's recuperating from measles? Do I slap the Bible out of his hand on Sunday? ~ Erma Bombeck

In the case of some people, not even if we had the most accurate scientific knowledge, would it be easy to persuade them were we to address them through the medium of that knowledge; for a scientific discourse, it is the privilege of education to appreciate, and it is impossible that this should extend to the multitude. ~ Aristotle.

What you don't learn in art theory is how too big a compliment can hurt more than a slap to the face. ~ Chuck Palahniuk

On the question of the world as a whole, science founders. For scientific knowledge the world lies in fragments, the more so the more precise our scientific knowledge becomes. ~ Karl Jaspers

A story about the Jack Spratts of medicine [was] told recently by Dr. Charles H. Best, co-discoverer of insulin. He had been invited to a conference of heart specialists in North America. On the eve of the meeting, out of respect for the fat-clogs-the-arteries theory, the delegates sat down to a special banquet served without fats. It was unpalatable but they all ate it as a duty. Next morning Best looked round the breakfast room and saw these same specialists - all in the 40-60 year old, coronary age group - happily tucking into eggs, bacon, buttered toast and coffee with cream. ~ Richard Mackarness

Imagine you're sitting having dinner in a restaurant. At some point during the meal, your companion leans over and whispers that they've spotted Lady Gaga eating at the table opposite. Before having a look for yourself, you'll no doubt have some sense of how much you believe your friends theory. You'll take into account all of your prior knowledge: perhaps the quality of the establishment, the distance you are from Gaga's home in Malibu, your friend's eyesight. That sort of thing. If pushed, it's a belief that you could put a number on. A probability of sorts. As you turn to look at the woman, you'll automatically use each piece of evidence in front of you to update your belief in your friend's hypothesis Perhaps the platinum-blonde hair is consistent with what you would expect from Gaga, so your belief goes up. But the fact that she's sitting on her own with no bodyguards isn't, so your belief goes down. The point is, each new observations adds to your overall assessment. This is all Bayes' theorem does: offers a systematic way to update your belief in a hypothesis on the basis of the evidence. It accepts that you can't ever be completely certain about the theory you are considering, but allows you to make a best guess from the information available. So, once you realize the woman at the table opposite is wearing a dress made of meat -- a fashion choice that you're unlikely to chance up on in the non-Gaga population -- that might be enough to tip your belief over the thresho ~ Hannah Fry

There's a respected theory in astronomy called Panspermia," Glinn finally continued. "It holds that life may have spread through the galaxy in bacteria or spores carried on meteorites or in clouds of dust. But ~ Douglas Preston

I've only read a few chapters of this book, Trumpet Blast Warning but it's amazing. All of his statements are backed up by original quotes & references from top politicians, the media, etc, so you can check for yourselves & discover this is not a conspiracy theory about world government, it's all backed by facts! All Christians, especially pastors & prayer groups really should read this book. Many thanks to Jason Carter for sending me a copy! ~ Jason Carter

The most important moments in a trial are often not seen by a jury. That is because it's one of the judge's main responsibilities to screen what they see and hear, lest they be prejudiced. It's the "you can't unring a bell" theory; once the jury hears something they shouldn't have heard, th trial is forever tainted.
If the damage is great enough, a mistrial is the result. Judges basically prefer nuclear war to mistrials. ~ David Rosenfelt

What we have here is a conflict of visions of reality. The world as you see it right here, right now, is reality, regardless of what the scientists say it might be. That's the way John sees it. But the world as revealed by its scientific discoveries is also reality, regardless of how it may appear, ~ Robert M. Pirsig

It cannot be that axioms established by argumentation should avail for the discovery of new works, since the subtlety of nature is greater many times over than the subtlety of argument. But axioms duly and orderly formed from particulars easily discover the way to new particulars, and thus render sciences active. ~ Francis Bacon

The oldest theory of art belongs to the Greeks, who regarded art as an imitation (mimesis) of reality. The strength of that theory is that it explains the way in which art takes its materials from real life. ~ Leland Ryken

Emotion is not a defect in an otherwise perfect reasoning machine. Reason, unfettered from human feeling, has led to as many horrors as any crusader's zeal. What use is pity in a world devoted to maximizing efficiency and productivity? Scientific husbandry tells us to weed out the sick, the infirm, the weak. The ruthless efficiency of euthanasia initiatives and ethnic cleansing are but the programmatic application of Nietzsche's point: from any quantifiable cost-benefit analysis, the principles of animal husbandry should apply to the human race. Charles Darwin himself acknowledged that strict obedience to "hard reason" rather than sympathy for fellow humans would represent a sacrifice of "the noblest part of our nature."6 It is the human heart resonating with empathy, not the logical brain attuned to the mathematics of efficiency, that revolts at cruelty and inhumanity.
