Nature Of Theory Quotes & Sayings

Like any other science, yoga is applicable by people of every clime and time. The theory advanced by certain ignorant writers that yoga is "dangerous" or "unsuitable" for Westerners is wholly false, and has lamentably deterred many sincere students from seeking its manifold blessings. Yoga is a method for restraining the natural turbulence of thoughts, which otherwise impartially prevents all men, of all lands, from glimpsing their true nature of Spirit. Like the healing light of the sun, yoga is beneficial equally to men of the East and to men of the West. The thoughts of most persons are restless and capricious; a manifest need exists for yoga: the science of mind control. — Paramahansa Yogananda

Ruskin's much-derided moral theory of art was part of an attempt to show that this human activity, which we value so highly, engaged the whole of human personality. His insistence on the sanctity of nature was part of an attempt to develop Goethe's intuition that form cannot be put together in the mind by an additive process, but is to be deduced from the laws of growth in living organisms, and their resistance to the elements. — Kenneth Clark

Freudian psychoanalytical theory is a mythology that answers pretty well to Levi-Strauss's descriptions. It brings some kind of order into incoherence; it, too, hangs together, makes sense, leaves no loose ends, and is never (but never) at a loss for explanation. In a state of bewilderment it may therefore bring comfort and relief ... give its subject a new and deeper understanding of his own condition and of the nature of his relationship to his fellow men. A mythical structure will be built up around him which makes sense and is believable-in, regardless of whether or not it is true. — Peter Medawar

General relativity is the cornerstone of cosmology and astrophysics. It has also provided the conceptual basis for string theory and other attempts to unify all the forces of nature in terms of geometrical structures. — Paul Davies

Quantum theory thus reveals a basic oneness of the universe. It shows that we cannot decompose the world into independently existing smallest units. As we penetrate into matter, nature does not show us any isolated "building blocks," but rather appears as a complicated web of relations between the various parts of the whole. These relations always include the observer in an essential way. The human observer constitute the final link in the chain of observational processes, and the properties of any atomic object can be understood only in terms of the object's interaction with the observer. — Fritjof Capra

But now at last the sacred influence
Of light appears, and rom the walls of Heav'n
Shoots far into the bosom of dim Night
A glimmering dawn; here Nature first begins
her farthest verge, and Chaos to retire
As from her outmost works a broken foe
With tumult less and with less hostile din, — John Milton

There is no theory of a God, of an author of Nature, of an origin of the Universe, which is not utterly repugnant to my faculties ... — Harriet Martineau

Meanwhile, the originator of a theory may have a very lonely time, especially if his colleagues find his views of nature unfamiliar, and difficult to appreciate. — Peter D. Mitchell

All rational knowledge is either material, and concerns some objects, or formal, and is occupied only with the form of understanding and reason itself and with the universal rules of thinking, without regard to distinctions among objects.
formal philosophy is called logic. Material philosophy, however, which has to do with definite object objects and the laws to which they are subject, is divided into two parts. This is because these laws are either laws of nature or laws of freedom. The science of the former is called physics, and that of the latter ethics. The former is also called theory of nature and the latter theory of morals. — Immanuel Kant

This is the Manifesto of Little Monster
There is something heroic about the way my fans operate their cameras. So precisely, so intricately and so proudly. Like Kings writing the history of their people, is their prolific nature that both creates and procures what will later be percieved as the kingdom. So the real truth about Lady Gaga fans, my little monsters, lies in this sentiment: They are the Kings. They are the Queens. They write the hisory of the kingdom and I am something of a devoted Jester. It is in the theory of perception that we have established our bond, or the lie I should say, for which we kill. We are nothing without our image. Without our projection. Without the spiritual hologram of who we percieve ourselves to be or rather to become, in the future.
When you are lonely,
I will be lonely too.
And this is the fame. — Lady Gaga

Superstring theories provide a framework in which the force of gravity may be united with the other three forces in nature: the weak, electromagnetic and strong forces. Recent progress has shown that the most promising superstring theories follow from a single theory. For the last generation, physicists have studied five string theories and one close cousin. Recently it has become clear that these five or six theories are different limiting cases of one theory which, though still scarcely understood, is the candidate for superunification of the forces of nature. — Edward Witten

Nowhere was Darwin able to point to one bona fide case of natural selection having actually generated evolutionary change in nature ... Ultimately, the Darwinian theory of evolution is no more nor less than the great cosmogenic myth of the twentieth century. — Michael Denton

...a useful coorective to the triumphalism of some scientists. For example, Maddox went out of his way to emphasise the provisional nature of much physics - he referred to black holes as 'putative' only, to the search for theories of everything as 'the embodiment of a belief, even a hope' and stated that the reason why the quantum gravity project is 'becalmed' right now is because 'the problem to be solved is not yet fully understood' and that the idea that the universe began with a Big Bang 'will be found to be false'. — Peter Watson

In the one real, time-drenched universe, everything has a particular history precisely because it is finite, and not part of an infinite array. Moreover, the cosmological use of the infinite serves to mask the failure of a physical theory taken beyond the boundaries of its proper domain of application. The most notable instance is the inference in contemporary cosmology of an infinite initial singularity from the field equations of general relativity. Finally, the admission of the mathematical infinite into natural science effaces the difference, which we emphasize, between nature and mathematics. Nature works in time, with which mathematics has trouble. Mathematics offers, among other things, the infinite, which nature abhors. — Lee Smolin

Since the beginning of physics, symmetry considerations have provided us with an extremely powerful and useful tool in our effort to understand nature. Gradually they have become the backbone of our theoretical formulation of physical laws. — Tsung-Dao Lee

Following the path of earlier unificationists, one of Eddington's aims was to reduce the contingencies in the description of nature, for example, by explaining the fundamental constants of physics rather than accepting them as merely experimental data. One of these constants was the fine-structure constant ... , which entered prominently in Dirac's theory and was known to be about 1/137. — Helge Kragh

I am convinced that it is impossible to expound the methods of induction in a sound manner, without resting them upon the theory of probability. Perfect knowledge alone can give certainty, and in nature perfect knowledge would be infinite knowledge, which is clearly beyond our capacities. We have, therefore, to content ourselves with partial knowledge-knowledge mingled with ignorance, producing doubt. — William Stanley Jevons

Nature normally hates power laws. In ordinary systems all quantities follow bell curves, and correlations decay rapidly, obeying exponential laws. But all that changes if the system is forced to undergo a phase transition. Then power laws emerge-nature's unmistakable sign that chaos is departing in favor of order. The theory of phase transitions told us loud and clear that the road from disorder to order is maintained by the powerful forces of self-organization and is paved by power laws. It told us that power laws are not just another way of characterizing a system's behavior. They are the patent signatures of self-organization in complex systems. — Albert-Laszlo Barabasi

Discovery commences with the awareness of anomaly, i.e. with the recognition that nature has somehow violated the paradigm-induced expectations that govern normal science. It then continues with a more or less extended exploration of the area of anomaly. And it closes only when the paradigm theory has been adjusted so that the anomalous has become the expected. — Thomas Kuhn

It is frequently said that speech that is intentionally provocative and therefore invites physical retaliation can be punished or suppressed. Yet, plainly no such general proposition can be sustained. Quite the contrary ... The provocative nature of the communication does not make it any the less expression. Indeed, the whole theory of free expression contemplates that expression will in many circumstances be provocative and arouse hostility. The audience, just as the speaker, has an obligation to maintain physical restraint. — Thomas I. Emerson

Aristotle and Bacon can therefore be seen respectively as the grandfather and the father of the modern branch of the philosophy of science called "confirmation theory," that is, the study of how scientific hypotheses and theories are confirmed by evidence. Evidence clearly has a very significant bearing on the decisions of scientific communities to accept or reject certain theories, but spelling out the precise nature of that relationship is difficult — Howard Margolis

But deep down I always knew there is no way to order chaos. It's the fundamental theory at the beginning and end of everything; it's the ultimate law of nature. There's no way to win against unpredictability, to suit up completely against accidents. — Alexandra Fuller

Unfortunately, most of the prevailing descriptions of quantum theory tend to emphasize puzzles and paradoxes in a way that makes philosophers, theologians, and even non-physicist scientists leery of actually using in any deep way the profound changes in our understanding of human beings in nature wrought by the quantum revolution. Yet, properly presented, quantum mechanics is thoroughly in line with our deep human intuitions. It is the 300 years of indoctrination with basically false ideas about how nature works that now makes puzzling a process that is completely in line with normal human intuition. — Paul Davies

An animal, at the end of a few months, is what it will be all its life; and its species, at the end of a thousand years, is what it was in the first of those thousand years. Why is man alone subject to becoming an imbecile? — Jean-Jacques Rousseau

I am more and more convinced that true revolutionaries must perceive the revolution, because of its creative and liberating nature, as an act of love. For me, the revolution, which is not possible without a theory of revolution - and therefore science - is not irreconcilable with love. — Che Guevera

Every person should embrace those [dogmas] that he, being the best judge of himself, feels will do most to strengthen in him love of justice. — Baruch Spinoza

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

Starting from the very reasonable, but unfortunately revolutionary concept that social practices which threaten the continuation of life on Earth must be changed, we need a theory of revolutionary ecology that will encompass social and biological issues, class struggle, and a recognition of the role of global corporate capitalism in the oppression of peoples and the destruction of nature. — Judi Bari

The UU Professor of Anthropics had developed the Special and Inevitable Anthropic Principle, which was that the entire reason for the existence of the universe was the eventual evolution of the UU Professor of Anthropics. But this was only a formal statement of the theory which absolutely everyone, with only some minor details of a "Fill in name here" nature, secretly believes to be true. — Terry Pratchett

No matter how we may single out a complex from nature ... its theoretical treatment will never prove to be ultimately conclusive ... I believe that this process of deepening of theory has no limits. — Albert Einstein

So we may now pose a question which could be answered only if we have a quantum theory of gravity. What is the nature of the information trapped in a quantum black hole? Keep this in mind as we go ahead and explore the different approaches to quantum gravity, for a good test of a theory of quantum gravity is how well it is able to answer this question. — Lee Smolin

Relativity was a highly technical new theory that gave new meanings to familiar concepts and even to the nature of the theory itself. The general public looked upon relativity as indicative of the seemingly incomprehensible modern era, educated scientists despaired of ever understanding what Einstein had done, and political ideologues used the new theory to exploit public fears and anxieties-all of which opened a rift between science and the broader culture that continues to expand today. — David C. Cassidy

I am now convinced that we have recently become possessed of experimental evidence of the discrete or grained nature of matter, which the atomic hypothesis sought in vain for hundreds and thousands of years. The isolation and counting of gaseous ions, on the one hand, which have crowned with success the long and brilliant researches of J.J. Thomson, and, on the other, agreement of the Brownian movement with the requirements of the kinetic hypothesis, established by many investigators and most conclusively by J. Perrin, justify the most cautious scientist in now speaking of the experimental proof of the atomic nature of matter, The atomic hypothesis is thus raised to the position of a scientifically well-founded theory, and can claim a place in a text-book intended for use as an introduction to the present state of our knowledge of General Chemistry. — Wilhelm, Ostwald

I am apt, however, to entertain a Suspicion, that the World is still too young to fix any general stable Truths in Politics, which will remain true to the latest Posterity. We have not as yet had Experience of above three thousand Years; so that not only the Art of Reasoning is still defective in this Science, as well as in all others, but we even want sufficient Materials, upon which we can reason. 'Tis not sufficiently known, what Degrees of Refinement, either in Virtue or Vice, human Nature is susceptible of; nor what may be expected of Mankind from any great Revolution in their Education, Customs, or Principles. — David Hume

The instinct to survive is human nature itself, and every aspect of our personalities derives from it. Anything that conflicts with the survival instinct acts sooner or later to eliminate the individual and thereby fails to show up in future generations ... A scientifically verifiable theory of morals must be rooted in the individual's instinct to survive
and nowhere else!
and must correctly describe the hierarchy of survival, note the motivations at each level, and resolve all conflicts.
We have such a theory now; we can solve any moral problem, on any level. Self-interest, love of family, duty to country, responsibility toward the human race ...
The basis of all morality is duty, a concept with the same relation to group that self-interest has to individual. — Robert A. Heinlein

The contemporary design argument does not rest, however, on gaps in our knowledge but rather on the growth in our knowledge due to the revolution in molecular biology. Information theory has taught us that nature exhibits two types of order. The first type is produced by natural causes-shiny crystals, hexagonal patterns in oil, whirlpools in the bathtub. But the second type-the complex structure of the DNA molecule-is not produced by any natural processes known to experience. — Nancy Pearcey

Through luminous and erudite readings of the texts, Hasana Sharp shows us how profound and radical is Spinoza's conception of nature and his claim that humans always remain part of nature, acting solely according to the same rules. She demonstrates the political consequences of adopting this perspective through a provocative intervention in contemporary feminist theory, while along the way opening promising avenues for future work in a variety of other fields, such as animal studies and ecology. This is a challenging and important book. — Michael Hardt

In the book, I make the point that here we have string theory and here we have twistor theory and we don't know if either one of them is the right approach to nature. — Roger Penrose

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

As Sommerfeld said in his famous text "Spectral Lines and Atomic Constitution," on which a generation of physicists learned the subject, "In the fine structure constant e is the representative of the electron theory, h the appropriate representative of the quantum theory, c comes from relativity and characterizes it in contrast to classical theory. — Emilio Segre

We may affirm of Mr. Buffon, that which has been said of the chemists of old; though he may have failed in attaining his principal aim, of establishing a theory, yet he has brought together such a multitude of facts relative to the history of the earth, and the nature of its fossil productions, that curiosity finds ample compensation, even while it feels the want of conviction. — Oliver Goldsmith

Einstein's theory, experimentally corroborated for the last hundred years, regardless of how outlandish and opposed to our prejudices (disguised as they are with the 'common sense' costume), is rational, consistent, and intelligible to the layperson - if s/he has the audacity of accepting the unfounded nature of those prejudices. — Felix Alba-Juez

The revolution which began with the creation of quantum theory and relativity theory can only be finished with their unification into a single theory that can give us a single, comprehensive picture of nature. — Lee Smolin

To seek pleasure, to avoid pain, is the general line of action (some would say law) of the organic world. Without this quest of the agreeable, life itself would be impossible. Organisms would disintegrate, life cease. Thus whatever a man's actions and line of conduct may be, he does what he does in obedience to a craving of his nature. The most repulsive actions, no less than actions which are indifferent or most attractive, are all equally dictated by a need of the individual who performs them. Let him act as he may, the individual acts as he does because he finds a pleasure in it, or avoids, or thinks he avoids, a pain. Here we have a well-established fact. Here we have the essence of what has been called the egoistic theory. — Pyotr Kropotkin

It's funny how our desires often tend to circle around the whims and fancies of others rather than the self. One school of thought has a convincing explanation that this is because we live in a society that makes us want to be pleasing to others more than the self--a rather selfless trait, so to think. But then there is this other theory which eventually concludes that we do all of this to please no one but the self...because praise and compliments are what the devil thrives on, and we are in no significant way any different. — Priyanka Naik

A full explanation of this is beyond the scope of this book, suffice to say that Einstein was forced into this bold move primarily because Maxwell's equations for electricity and magnetism were incompatible with Newton's 200-year-old laws of motion. Einstein abandoned the Newtonian ideas of space and time as separate entities and merged them. In Einstein's theory there is a special speed built into the structure of spacetime itself that everyone must agree on, irrespective of how they are moving relative to each other. This special speed is a universal constant of nature that will always be measured as precisely 299,792,458 metres (983,571,503 feet) per second, at all times and all places in the Universe, no matter what they are doing. This — Brian Cox

In consequence of Darwin's reformed Theory of Descent, we are now in a position to establish scientifically the groundwork of a non-miraculous history of the development of the human race ... If any person feels the necessity of conceiving the coming into existence of this matter as the work of a supernatural creative power, of the creative force of something outside of matter, we have nothing to say against it. But we must remark, that thereby not even the smallest advantage is gained for a scientific knowledge of nature. Such a conception of an immaterial force, which as the first creates matter, is an article of faith which has nothing whatever to do with human science. — Ernst Haeckel

Every man - in the development of his own personality - has the right to form his own beliefs and opinions. Hence, suppression of belief, opinion and expression is an affront to the dignity of man, a negation of man's essential nature.
[Toward a General Theory of the First Amendment (1963)] — Thomas I. Emerson

The puzzle of time, the mystery of creation, the problem of evil, the enigma of knowledge, the state of soul, the vexations of probability theory of the nature of God's grace, all reduced to a single question. What does it mean, in a world of God's creation, that man is free to choose between the paths of good and evil? — Bernard Beckett

All science has one aim, namely, to find a theory of nature. We have theories of races and of functions, but scarcely yet a remote approach to an idea of creation. We are now so far from the road to truth, that religious teachers dispute and hate each other, and speculative men are esteemed unsound and frivolous. But to a sound judgment, the most abstract truth is the most practical. Whenever a true theory appears, it will be its own evidence. Its test is, that it will explain all phenomena. Now many are thought not only unexplained but inexplicable; as language, sleep, madness, dreams, beasts, sex. — Ralph Waldo Emerson

Liberalism makes this mistake in regard to private property and Marxism makes it in regard to socialized property ... The Marxist illusion is partly derived from a romantic conception of human nature ... It assumes that the socialization of property will eliminate human egotism ... The development of a managerial class in Russia, combing economic with political power, is an historic refutation of the Marxist theory. — Reinhold Niebuhr

There is an old debate," Erdos liked to say, "about whether you create mathematics or just discover it. In other words, are the truths already there, even if we don't yet know them?" Erdos had a clear answer to this question: Mathematical truths are there among the list of absolute truths, and we just rediscover them. Random graph theory, so elegant and simple, seemed to him to belong to the eternal truths. Yet today we know that random networks played little role in assembling our universe. Instead, nature resorted to a few fundamental laws, which will be revealed in the coming chapters. Erdos himself created mathematical truths and an alternative view of our world by developing random graph theory. Not privy to nature's laws in creating the brain and society, Erdos hazarded his best guess in assuming that God enjoys playing dice. His friend Albert Einstein, at Princeton, was convinced of the opposite: "God does not play dice with the universe. — Albert-Laszlo Barabasi

However we select from nature a complex [of phenomena] using the criterion of simplicity, in no case will its theoretical treatment turn out to be forever appropriate (sufficient) ... I do not doubt that the day will come when [general relativity], too, will have to yield to another one, for reasons which at present we do not yet surmise. I believe that this process of deepening theory has no limits. — Albert Einstein

He didn't like violence, no matter what he'd told Jessica before. He was good at it, no denying that, but he did not like it. Yes, violence was the closest modern man came to his true primitive self, the closest he came to the intended state of nature, to the Lockean ideal, if you will. And yes, violence was the ultimate test of man, a test of both physical strength and animalistic cunning. But it was still sickening. Man had - in theory anyway - evolved for a reason. In the final analysis, violence was indeed a rush. But so was skydiving without a parachute. — Harlan Coben

First of all, when we are all finished, and we have a mathematical theory by which we can compute consequences, what can we do? It really is an amazing thing. In order to figure out what an atom is going to do in a given situation we make up rules with marks on paper, carry them into a machine which has switches that open and close in some complicated way, and the result will tell us what the atom is going to do! If the way that these switches open and close were some kind of model of the atom, if we thought that the atom had switches in it, then I would say that I understood more or less what is going on. I find it quite amazing that it is possible to predict what will happen by mathematics, which is simply following rules which really have nothing to do with what is going on in the original thing. The closing and opening of switches in a computer is quite different from what is happening in nature. — Anonymous

The nature of catastrophe is, after all, reasonably unvarying in the way it ruins, destroys, wounds and devastates. But if something can be learned from the event - not least something as profound as the theory of plate tectonics - then it somehow puts the ruination into a much more positive light. — Simon Winchester

How strange it would be if the final theory were to be discovered in our lifetimes! The discovery of the final laws of nature will mark a discontinuity in human intellectual history, the sharpest that has occurred since the beginning of modern science in the seventeenth century. Can we now imagine what that would be like? — Steven Weinberg

Ethics is not a bitter wind in one's face, stinging a person with injunctions to act against his interest, but a breeze at one's back, aiding a person toward the achievement of life-enhancing values. Morality is not a burden to be resented or scrimped on, complied with only grudgingly. If Rand's theory of the nature of morality is correct, cutting moral corners amounts to cutting one's own throat. Far from being a necessary evil, ethics is a necessary ally, an indispensable tool for living. To the extent that a moral code accurately identifies a life-promoting course, morality is a tremendous benefactor. — Tara Smith

Time decides the limits of existence. Nothing can be infinite if it exists in time. — Raheel Farooq

Quantum field theory arose out of our need to describe the ephemeral nature of life. — Anthony Zee

String theory, therefore, is rich enough to explain all the fundamental laws of nature. Starting from a simple theory of a vibrating string, one can extract the theory of Einstein, Kaluza-Klein theory, supergravity, the Standard Model, and even GUT theory. It seems nothing less than a miracle that, starting from some purely geometric arguments from a string, one is able to rederive the entire progress of physics for the past 2 milleninia. All the theories so far discussed in this book are automatically included in string theory. — Michio Kaku

The only distinguishing characteristic of a literature professor at the millennium was that he or she wrote about other people's writing. Apart from that, the writing he wrote about didn't even need to be literature, or writing about literature, or even writing about writing about literature. He needed theory...In the unflickering glare, at the center of a severe perspective, Nelson suddenly felt the visceral truth of the world as text; he apperceived the fundamentally linguistic nature of reality. Everything was text, at every level of existence, all the way up from quarks to queer theory. Words arranged in lines; lines arrayed on pages; pages pressed together, bound, and trimmed in books; books arranged cover to cover along a shelf like the words in a line of text; shelves stacked one atop the other like lines of text on a page; rows of shelves pressed together, with just the barest passage for the reader, like the pages of a book. — James Hynes

A successful unification of quantum theory and relativity would necessarily be a theory of the universe as a whole. It would tell us, as Aristotle and Newton did before, what space and time are, what the cosmos is, what things are made of, and what kind of laws those things obey. Such a theory will bring about a radical shift - a revolution - in our understanding of what nature is. It must also have wide repercussions, and will likely bring about, or contribute to, a shift in our understanding of ourselves and our relationship to the rest of the universe. — Lee Smolin

One day [Rabbi Spear] talked about his theory of happiness. He proposed that human feelings respond only to contrast and change, not to constancy, just as eyesight responds to contrasts of light and dark and to movement. The rabbi speculated that if emotions are similar to eyesight and other senses, then perhaps emotions were developed by nature as a survival mechanism. — Alan Lightman

On the spiritual theory, man consists essentially of a spiritual nature or mind intimately associated with a spiritual body or soul, both of which are developed in and by means of a material organism. — Alfred Russel Wallace

And because the constitution of a mans Body, is in continuall mutation; it is impossible that all the same things should alwayes cause in him the same Appetites, and aversions; much lesse can all men consent, in the Desire of almost any one and the same Object.
Good Evill
But whatsoever is the object of any mans Appetite or Desire; that is it, which he for his part calleth Good: And the object of his Hate, and Aversion, evill, And of his contempt, Vile, and Inconsiderable. For these words of Good, evill, and Contemptible, are ever used with relation to the person that useth them: There being nothing simply and absolutely so; nor any common Rule of Good and evill, to be taken from the nature of the objects themselves; but from the Person of the man (where there is no Common-wealth;) or, (in a Common-wealth,) From the Person that representeth it; or from an Arbitrator or Judge, whom men disagreeing shall by consent set up, and make his sentence the Rule thereof. — Thomas Hobbes

I can imagine no greater catastrophe than if I were mistaken, and the theory were correct that what I consider secondary instincts or drives are actually primary instincts! Because in that case the emotional plague would rest upon the support of a natural law while its archenemies, truth and sociality, would be relying upon unfounded ethics. Until now both lies and truth have taken recourse to ethics. But only lies have profited because they were able to appear under the guise of truth. Under these circumstances, egoism, theft, petty selfishness, slander, etc., would be the natural rule. (26.july.1943) — Wilhelm Reich

Practical wisdom is only to be learned in the school of experience. Precepts and instruction are useful so far as they go, but, without the discipline of real life, they remain of the nature of theory only. — Samuel Smiles

The very nature of the quantum theory ... forces us to regard the space-time coordination and the claim of causality, the union of which characterizes the classical theories, as complementary but exclusive features of the description, symbolizing the idealization of observation and description, respectively. — Niels Bohr

Despite the earnest belief of most of his fans, Einstein did not win his Nobel Prize for the theory of relativity, special or general. He won for explaining a strange effect in quantum mechanics, the photoelectric effect. His solution provided the first real evidence that quantum mechanics wasn't a crude stopgap for justifying anomalous experiments, but actually corresponds to reality. And the fact that Einstein came up with it is ironic for two reasons. One, as he got older and crustier, Einstein came to distrust quantum mechanics. Its statistical and deeply probabilistic nature sounded too much like gambling to him, and it prompted him to object that "God does not play dice with the universe." He was wrong, and it's too bad that most people have never heard the rejoinder by Niels Bohr: "Einstein! Stop telling God what to do. — Sam Kean

The new "theory of justice" demands that men counteract the "injustice" of nature by instituting the most obscenely unthinkable injustice among men: deprive "those favored by nature" (i.e., the talented, the intelligent, the creative) of the right to the rewards they produce (i.e., the right to life) - and grant to the incompetent, the stupid, the slothful a right to the effortless enjoyment of the rewards they could not produce, could not imagine, and would not know what to do with. — Ayn Rand

In the ensuing chapters, we will look in some detail at particular manifestations of the modern scientific ideology and the false paths down which it has led us. We will consider how biological determinism has been used to explain and justify inequalities within and between societies and to claim that those inequalities can never be changed. We will see how a theory of human nature has been developed using Darwin's theory of evolution by natural selection to claim that social organization is also unchangeable because it is natural. We will see how problems of health and disease have been located within the individual so that the individual becomes a problem for society to cope with rather than society becoming a problem for the individual. And we will see how simple economic relationships masquerading as facts of nature can drive the entire direction of biological research and technology. — Richard C. Lewontin

As for myself, I can only exhort you to look on Friendship as the most valuable of all human possessions, no other being equally suited to the moral nature of man, or so applicable to every state and circumstance, whether of prosperity or adversity, in which he can possibly be placed. But at the same time I lay it down as a fundamental axiom that "true Friendship can only subsist between those who are animated by the strictest principles of honour and virtue." When I say this, I would not be thought to adopt the sentiments of those speculative moralists who pretend that no man can justly be deemed virtuous who is not arrived at that state of absolute perfection which constitutes, according to their ideas, the character of genuine wisdom. This opinion may appear true, perhaps, in theory, but is altogether inapplicable to any useful purpose of society, as it supposes a degree of virtue to which no mortal was ever capable of rising. — Marcus Tullius Cicero

Not even on the most distorted and contracted theory of good which ever was framed by religious or philosophical fanaticism, can the government of Nature be made to resemble the work of a being at once good and omnipotent. — John Stuart Mill

Sometimes difficulty clarifies things. And sometimes realizing that the road you've chosen is a demanding one gives you the courage to stay on that road. It reveals the nature of our relationship with God. It sounds cute and comforting to say "God is in control," and people who say that may imagine sitting on their daddy's lap behind the wheel of the family car, going "Vroom vroomy vroom!" while Daddy does the steering. In reality, when God is in control, it feels more like one of those movies where some amateur has to step up and land the airplane or steer the ship to safety through a crashing storm, with an expert giving them instructions remotely through a headset. In theory, following the expert's instructions will help us get in safely; but our fear, panic, self-doubt, and lack of skill are not exactly comforting. Yes, God is in control, but we're the ones who are in for a rough ride. — Simcha Fisher

The current leading candidates for dark matter are particles predicted to exist from supersymmetric theories, extensions of current particle physics that include a new symmetry of Nature. The reader may recognize the "super" in supersymmetry from superstring theory, a candidate theory for unifying general relativity and quantum mechanics. As of the winter of 2014, no evidence for supersymmetry had been found, despite decades of intense search and the enthusiastic support of many physicists. At this point, it is unclear and somewhat doubtful that supersymmetry is realized in Nature. — Marcelo Gleiser

It was Einstein's dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein's day hadn't made enough progress in understanding the forces of nature for that to be a realistic goal. — Stephen Hawking

Movements for animal rights are not irrational denials of human uniqueness; they are a clear-sighted recognition of connection across the discredited breach of nature and culture. Biology and evolutionary theory over the last two centuries have simultaneously produced modern organisms as objects of knowledge and reduced the line between humans and animals to a faint trace re-etched in ideological struggle or professional disputes between life and social science. Within this framework, teaching modern Christian creationism should be fought as a form of child abuse. — Donna J. Haraway

To sum up: all nature-spirits are not the same as fairies; nor are all fairies nature-spirits. The same applies to the relationship of nature-spirits and the dead. But we may safely say that a large proportion of nature-spirits became fairies, while quite a number of the dead in some areas seem to take on the character of nature-spirits. We cannot expect any fixity of rule in dealing with barbaric thought. We must take it as it comes. It bears the same relationship to "civilized" or folk-lore theory as does the growth of the jungle to a carefully designed and meticulously labelled botanical garden. As Victor Hugo once exclaimed when writing of the barbaric confusion which underlies the creative function in poetry: 'What do you expect? You are among savages! — Lewis Spence

Yes, I am very lucky, but I have a little theory about this. I have noticed through experience and observation that providence, nature, God, or what I would call the power of creation seems to favor human beings who accept and love life unconditionally, and I am certainly one who does with all my heart. — Arthur Rubinstein

Physical reality cannot account for its own existence for the simple reason that nature - the physical - is that which by definition already exists; existence, even taken as a simple brute fact to which no metaphysical theory is attached, lies logically beyond the system of causes that nature comprises; it is, quite literally, "hyperphysical," or, shifting into Latin, super naturam. — David Bentley Hart

The world is in some essential sense a construct. Human knowledge is radically interpretive. There are no perspective-independent facts. Every act of perception and cognition is contingent, mediated, situated, contextual, theory-soaked. Human language cannot establish its ground in an independent reality. Meaning is rendered by the mind and cannot be assumed to inhere in the object, in the world beyond the mind, for that world can never be contacted without having already been saturated by the mind's own nature. That world cannot even be justifiably postulated. Radical uncertainty prevails, for in the end what one knows and experiences is to an indeterminate extent a projection. — Richard Tarnas

Throughout these lectures I have delighted in showing you that the price of gaining such an accurate theory has been the erosion of our common sense. We must accept some very bizarre behavior: the amplification and suppression of probabilities, light reflecting from all parts of a mirror, light travelling in paths other than a straight line, photons going faster or slower than the conventional speed of light, electrons going backwards in time, photons suddenly disintegrating into a positron-electron pair, and so on. That we must do, in order to appreciate what Nature is really doing underneath nearly all the phenomena we see in the world. — Richard Feynman

[ ... ] without much ardor but quite unmistakably, she was writhing her hips as if she were dancing. When he was very close, he saw' her gaping mouth: she was yawning lengthily, insatiably: the great open hole was rocking gently atop die mechanically dancing body. Jean-Marc thought: she's dancing and she's bored.
He reached the seawall: down below, on the beach, he saw men with their heads thrown back releasing kites into the air. They were doing it with passion, and Jean-Marc recalled his old theory: there are three kinds of boredom: passive boredom: the girl dancing and yawning; active boredom: kite-lovers; and rebellious boredom: young people burning cars and smashing shop windows. — Milan Kundera

It is not that we propose a theory and Nature may shout NO; rather, we propose a maze of theories, and Nature may shout INCONSISTENT. — Imre Lakatos

In this book, you will encounter various interesting geometries that have been thought to hold the keys to the universe. Galileo Galilei (1564-1642) suggested that "Nature's great book is written in mathematical symbols." Johannes Kepler (1571-1630) modeled the solar system with Platonic solids such as the dodecahedron. In the 1960s, physicist Eugene Wigner (1902-1995) was impressed with the "unreasonable effectiveness of mathematics in the natural sciences." Large Lie groups, like E8-which is discussed in the entry "The Quest for Lie Group E8 (2007)"- may someday help us create a unified theory of physics. in 2007, Swedish American cosmologist Max Tegmark published both scientific and popular articles on the mathematical universe hypothesis, which states that our physical reality is a mathematical structure-in other words, our universe in not just described by mathematics-it is mathematics. — Clifford A. Pickover

This is very nice, cozy. You got a nice cozy place, Lublin."
"Cramped," Rosa said.
"I work from a different theory. For everything, there's a bad way of describing, also a good way. You pick the good way, you go along better."
"I don't like to give myself lies," Rosa said.
"Life is short, we all got to lie. — Cynthia Ozick

A third reason scientists are reluctant to examine paranormal phenomena is that they appear to contradict known physical laws. What is the point of studying the impossible? Only a fool would waste his time. The problem of data in conflict with existing theory cannot be overstated. Arthur Eddington once said you should never believe any experiment until it has been confirmed by theory, but this humorous view has a reality that cannot be discounted. — Michael Crichton

Evolution in nature is not inconsistent with the notion of creation, because evolution requires the creation of beings that evolve. — Pope Francis

I think that people with autism are born outside the regime of civilization. Sure, this is just my own made-up theory, but I think that, as a result of all the killings in the world and the selfish planet-wrecking that humanity has committed, a deep sense of crisis exists. Autism has somehow arisen out of this. Although people with autism look like other people physically, we are in fact very different in many ways. We are more like travelers from the distant, distant past. And if, by our being here, we could help the people of the world remember what truly matters for the Earth, that would give us a quiet pleasure. — Naoki Higashida

There is no such thing as "healthy" competition within a knowledge organization; all internal competition is destructive. The nature of our work is that it cannot be done by any single person in isolation. Knowledge work is by definition collaborative. — Tom DeMarco

The leap from maps to fluid flow seemed so great that even those most responsible sometimes felt it was like a dream. How nature could tie such complexity to such simplicity was far from obvious. "You have to regard it as a kind of miracle, not like the usual connection between theory and experiment," Jerry Gollub said. Within a few years, the miracle was being repeated again and again in a vast bestiary of laboratory systems: bigger fluid cells with water and mercury, electronic oscillators, lasers, even chemical reactions. Theorists adapted Feigenbaum's techiniques and found other mathematical routes to chaos, cousins of period-doubling: such patterns as intermittency and quasiperiodicity. These, too, proved universal in theory and experiment. — James Gleick

The error I found in the philosophy of Henry George was its cocksureness, its simplicity, and the small value that it placed upon the selfish motives of men. The doctrine was a hang-over from the seventeenth century in France, when the philosophers had given up the idea of God, but still thought that there must be some immovable basis for man's conduct and ideals. In this dilemma they evolved the theory of natural rights. If 'natural rights' means anything it means that the individual rights are to be determined by the conduct of Nature. But Nature knows nothing about rights in the sense of human conception. — Clarence Darrow

If the deep logic of what determines the value of the fine-structure constant also played a significant role in our understanding of all the physical processes in which the fine-structure constant enters, then we would be stymied. Fortunately, we do not need to know everything before we can know something. — John D. Barrow

At our base level we are animals. And so, my theory is that women are only considered attractive as long as they look fertile because we, as humans, are made to reproduce and move on. And so we kind of can't ever get away from our animalistic nature, in a way. — Erin Davie

The beauty of string theory is the metaphor kind of really comes very close to the reality. The strings of string theory are vibrating the particles, vibrating the forces of nature into existence, those vibrations are sort of like musical notes. So string theory, if it's correct, would be playing out the score of the universe. — Brian Greene

Everyone has a theory of human nature. Everyone has to anticipate the behavior of others, and that means we all need theories about what makes people tick. — Steven Pinker

There is a theory that watching unbearable stories about other people lost in grief and rage is good for you - may cleanse you of your darkness. Do you want to go down to the pits of yourself all alone? Not much. What if an actor could do it for you? Isn't that why they are called actors? They act for you. You sacrifice them to action. And this sacrifice is a mode of deepest intimacy of you with your own life. Within it you watch [yourself] act out the present or possible organization of your nature. You can be aware of your own awareness of this nature as you never are at the moment of experience. The actor, by reiterating you, sacrifices a moment of his own life in order to give you a story of yours. — Anne Carson

There are wholes, the behavior of which is not determined by that of their individual elements, but where the part-processes are themselves determined by the intrinsic nature of the whole. It is the hope of Gestalt theory to determine the nature of such wholes. — Max Wertheimer

Agricultural practice served Darwin as the material basis for the elaboration of his theory of Evolution, which explained the natural causation of the adaptation we see in the structure of the organic world. That was a great advance in the knowledge of living nature. — Trofim Lysenko
