Concepts Theory Quotes & Sayings

With the subsequent strong support from cybernetics , the concepts of systems thinking and systems theory became integral parts of the established scientific language, and led to numerous new methodologies and applications
systems engineering, systems analysis, systems dynamics, and so on. — Fritjof Capra

One of the main functions of an analogy or model is to suggest extensions of the theory by considering extensions of the analogy, since more is known about the analogy than is known about the subject matter of the theory itself ... A collection of observable concepts in a purely formal hypothesis suggesting no analogy with anything would consequently not suggest either any directions for its own development. — Mary Hesse

I learnt to distrust all physical concepts as the basis for a theory. Instead one should put one's trust in a mathematical scheme, even if the scheme does not appear at first sight to be connected with physics. One should concentrate on getting interesting mathematics. — Paul Dirac

According to a 1995 study, a sample of Japanese eighth graders spent 44 percent of their class time inventing, thinking, and actively struggling with underlying concepts. The study's sample of American students, on the other hand, spent less than 1 percent of their time in that state. "The Japanese want their kids to struggle," said Jim Stigler, the UCLA professor who oversaw the study and who cowrote The Teaching Gap with James Hiebert. "Sometimes the [Japanese] teacher will purposely give the wrong answer so the kids can grapple with the theory. American teachers, though, worked like waiters. Whenever there was a struggle, they wanted to move past it, make sure the class kept gliding along. But you don't learn by gliding. — Daniel Coyle

In geometry I find certain imperfections which I hold to be the reason why this science, apart from transition into analytics, can as yet make no advance from that state in which it came to us from Euclid.
As belonging to these imperfections, I consider the obscurity in the fundamental concepts of the geometrical magnitudes and in the manner and method of representing the measuring of these magnitudes, and finally the momentous gap in the theory of parallels, to fill which all efforts of mathematicians have so far been in vain. — Nikolai Lobachevsky

What we have forgotten is that thoughts and words are conventions, and that it is fatal to take conventions too seriously. A convention is a social convenience, as, for example, money ... but it is absurd to take money too seriously, to confuse it with real wealth ... In somewhat the same way, thoughts, ideas and words are "coins" for real things. — Alan W. Watts

In order to achieve a true understanding of string theory, some new idea will be required, and most likely, some break with the concepts on which we've traditionally based physical theory. — David Gross

Henceforth, whilst there are a great many theories and models proposed as to how, or why, magic works (based on subtle energies, animal magnetism, psychological concepts, quantum theory, mathematics or the so-called anthropomorphic principle) it is not a case that one of them is more 'true' than others, but a case of which theory or model you choose to believe in, or which theory you find most attractive. Indeed, from a Chaos Magic perspective, you can selectively believe that a particular theory or model of magical action is true only for the duration of a particular ritual or phase of work. — Phil Hine

the process of learning a theory depends upon the study of applications, including practice problem-solving both with a pencil and paper and with instruments in the laboratory. If, for example, the student of Newtonian dynamics ever discovers the meaning of terms like 'force,' 'mass,' 'space,' and 'time,' he does so less from the incomplete though sometimes helpful definitions in his text than by observing and participating in the application of these concepts to problem-solution. That — Thomas S. Kuhn

Our deepest description of physical reality, in quantum theory and in the four Core Theories of forces (gravitation, electromagnetism, strong and weak forces), bring in concepts that call to mind yin and yang. Niels Bohr, an influential founder of quantum theory, saw strong parallels between his concept of complementarity and the unified duality of yin-yang. He designed a coat of arms for himself, in which the yin-yang figures centrally (see figure 42, page 324). Our Core Theories center on the interplay between lightlike space filling fluids (yang) and substances (yin) they both direct and respond to. — Frank Wilczek

In 1975, ... [speaking with Shiing Shen Chern], I told him I had finally learned ... the beauty of fiber-bundle theory and the profound Chern-Weil theorem. I said I found it amazing that gauge fields are exactly connections on fiber bundles, which the mathematicians developed without reference to the physical world. I added, "this is both thrilling and puzzling, since you mathematicians dreamed up these concepts out of nowhere." He immediately protested: "No, no. These concepts were not dreamed up. They were natural and real." — Chen-Ning Yang

All significant concepts of the modern theory of the state are secularized theological concepts not only because of their historical development - in which they were transferred from theology to the theory of the state, whereby, for example, the omnipotent god became the omnipotent lawgiver - but also because of their systematic structure, the recognition of which is necessary for a sociological consideration of these concepts. The exception in jurisprudence is analogous to the miracle in theology. Only by being aware of this analogy can we appreciate the manner in which the philosophical ideas of the state developed in the last centuries. — Carl Schmitt

Students using astrophysical textbooks remain essentially ignorant of even the existence of plasma concepts, despite the fact that some of them have been known for half a century. The conclusion is that astrophysics is too important to be left in the hands of astrophysicists who have gotten their main knowledge from these textbooks. Earthbound and space telescope data must be treated by scientists who are familiar with laboratory and magnetospheric physics and circuit theory, and of course with modern plasma theory. — Hannes Alfven

Before the 1940s the terms "system" and "systems thinking" had been used by several scientists, but it was Bertalanffy's concepts of an open system and a general systems theory that established systems thinking as a major scientific movement — Fritjof Capra

Thus it can be argued that quantum theory provides an opening for an idea of nature and of our role within it that is in general accord with certain religious concepts, but that, by contrast, is quite incompatible with the precepts of mechanistic deterministic classical physics. Thus the replacement of classical mechanics by quantum mechanics opens the door to religious possibilities that formerly were rationally excluded. — Paul Davies

I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics. — Max Born

It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory ... — Albert Einstein

There is no real person whose embodiment plays no role in meaning, whose meaning is purely objective and defined by the external world, and whose language can fit the external world with no significant role played by mind, brain, or body. Because our conceptual systems grow out of our bodies, meaning is grounded in and through our bodies. Because a vast range of our concepts are metaphorical, meaning is not entirely literal and the classical correspondence theory of truth is false. — George Lakoff

In its first 30 years of existence, up to the mid 1970s, the practical applications of game theory were very limited, probably as a result of excessive preoccupation by game theorists with cooperative solution concepts. — John Harsanyi

You must have also observed the masculine bias in the English language itself, in which women - literally, 'not men' - are daily confronted with the terror, unknowable to men, of concepts which they can imagine, but which an inherently patriarchal language does not allow them to express. — Dexter Palmer

It goes without saying that it is the traditionally minded Hindu we have in view, and not one whose hereditary dispositions have deviated in an anti-traditional direction, to the point of proving that "corruptio optimi pessima." Hinduism, strictly speaking, has no "dogmas" in the sense that every concept may be denied, on condition that the argument used is intrinsically true; which amounts to saying that concepts can be denied from the standpoint of a higher level of truth, metaphysics standing above cosmology and realization above theory as such. However, on their own level, the scriptural symbols of Hinduism are just as immovable as the Semitic dogmas, and this excludes any fallacious comparison of Hindu doctrine with the opinions of philosophers. No orthodox Hindu can maintain that the Veda has been mistaken on any point whatsoever. — Frithjof Schuon

If a psychological Maxwell devises a general theory of mind, he may make it possible for a psychological Einstein to follow with a theory that the mental and the physical are really the same. But this could happen only at the end of a process which began with the recognition that the mental is something completely different from the physical world as we have come to know it through a certain highly successful form of detached objective understanding. Only if the uniqueness of the mental is recognized will concepts and theories be devised especially for the purpose of understanding it. — Thomas Nagel

In philosophy, metaphorical pluralism is the norm. Our most important abstract philosophical concepts, including time, causation, morality, and the mind, are all conceptualized by multiple metaphors, sometimes as many as two dozen. What each philosophical theory typically does is to choose one of those metaphors as "right," as the true literal meaning of the concept. One reason there is so much argumentation across philosophical theories is that different philosophers have chosen different metaphors as the "right" one, ignoring or taking as misleading all other commonplace metaphorical structurings of the concept. Philosophers have done this because they assume that a concept must have one and only one logic. But the cognitive reality is that our concepts have multiple metaphorical structurings. — George Lakoff

I once knew an otherwise excellent teacher who compelled his students to perform all their demonstrations with incorrect figures, on the theory that it was the logical connection of the concepts, not the figure, that was essential. — Ernst Mach

The theory of conceptual semantics, which proposes that word senses are mentally represented as expressions in a richer and more abstract language of thought, stands at the center of this circle, compatible with all of the complications. Word meanings can vary across languages because children assemble and fine-tune them from more elementary concepts. They can be precise because the concepts zero in on some aspects of reality and slough off the rest. And they can support our reasoning because they represent lawful aspects of reality-space, time, causality, objects, intentions, and logic-rather than the system of noises that developed in a community to allow them to communicate. Conceptual semantics fits, too, with our commonsense notion that words are not the same as thoughts, and indeed, that much of human wisdom consists of not mistaking one for the other. — Steven Pinker

The parallelism, or denial of any causation between mind and body, derives basically, and fallaciously, from a theory of substances as having complete concepts that include everything that is true of them. — Gonzalo Rodriguez-Pereyra

The research I present in this book moves within a complex position: palpable tensions exist alongside exciting possibilities. CBPR methodologies emerged from critiques of conventional researcher-driven approaches and from scholarship and activism that names and problemitizes the power imbalances in current practices. CBPR strives to conduct research based in communities and founded upon core community values. With these broader critiques in mind, I wanted to consider how archaeology might be practiced if the concepts of decolonization and postcolonial theory were applied to the discipline. How might archaeological research change to create a reciprocal practice that truly benefits communities, at least as much as it benefits the scholarly interests of archaeologists? — Sonya Atalay

Where these reduced (operational - E.W.) concepts govern the analysis of the human reality, individual or social, mental or material, they arrive at a false concreteness - a concreteness isolated from the conditions which constitute its reality. In this context, the operational treatment of the concept assumes a political function. The individual and his behavior are analyzed in a therapeutic sense - adjustment to his society. Thought and expression, theory and practice are to be brought in line with the facts of his existence without leaving room for the conceptual critique of these facts. — Herbert Marcuse

Being exposed to theory, stimulated by a basic love of concepts and mathematics, was a marvelous experience. — Rudolph A. Marcus

Spiritual activity, education, civilization, culture, the idea are all vague, indefinite concepts, under the banner of which it is quite convenient to use words that have a still less clear meaning and therefore can easily be plugged into any theory. — Leo Tolstoy

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

That's really part of being a grounded theory researcher - putting names to concepts and experiences that people have. — Brene Brown

The theory of relativity worked out by Mr. Einstein, which is in the domain of natural science, I believe can also be applied to the political field. Both democracy and human rights are relative concepts - and not absolute and general. — Jiang Zemin

For strictly scientific or technological purposes all this is irrelevant. On a pragmatic view, as on a religious view, theory and concepts are held in faith. On the pragmatic view the only thing that matters is that the theory is efficacious, that it 'works' and that the necessary preliminaries and side issues do not cost too much in time and effort. Beyond that, theory and concepts go to constitute a language in which the scientistic matters at issue can be formulated and discussed. — Bertram Brockhouse

Socialism is not about big concepts and heavy theory. Socialism is about decent shelter for those who are homeless. It is about water for those who have no safe drinking water. It is about health care, it is about a life of dignity for the old. It is about overcoming the huge divide between urban and rural areas. It is about a decent education for all our people. Socialism is about rolling back the tyranny of the market. As long as the economy is dominated by an unelected, privileged few, the case for socialism will exist. — Chris Hani

The importance of C.F. Gauss for the development of modern physical theory and especially for the mathematical fundament of the theory of relativity is overwhelming indeed; also his achievement of the system of absolute measurement in the field of electromagnetism. In my opinion it is impossible to achieve a coherent objective picture of the world on the basis of concepts which are taken more or less from inner psychological experience. — Albert Einstein

I think actually if you take the analogy with other areas of engineering, and increasingly of science and even mathematics, you can see people do not have to learn the vast number of formulae they used to learn. Instead, they have to learn to use the computer effectively. This frees them, I feel, to understand concepts and the foundations while they're learning the mechanics of the application of the theory. — C.A.R. Hoare

We are caught up in a paradox, one which might be called the paradox of conceptualization. The proper concepts are needed to formulate a good theory, but we need a good theory to arrive at the proper concepts. — Abraham Kaplan

There ought not be two histories, one of political and moral action and one of political and moral theorizing, because there were not two pasts, one populated only by actions, the other only by theories. Every action is the bearer and expression of more or less theory-laden beliefs and concepts; every piece of theorizing and every expression of belief is a politcal and moral action. — Alasdair McIntyre

Almost all the other fellows do not look from the facts to the theory but from the theory to the facts; they cannot get out of the network of already accepted concepts; instead, comically, they only wriggle about inside. — Albert Einstein

Constraint theory asks: What is the price for doing this? Now one way around constraint theory is declaring your enemy crazy. Crazy and stupid are not concepts used in forecasting. When people say they're really stupid or they're crazy, that's laziness. That means I don't want to think through their position or about what they're really going to do. — George Friedman

The fact of evolution is the backbone of biology, and biology is thus in the peculiar position of being a science founded on an unproved theory -is it then a science or a faith? Belief in the theory of evolution is thus exactly parallel to belief in special creation - both are concepts which believers know to be true but neither, up to the present, has been capable of proof. — L. Harrison Matthews

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

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

open coding; development of concepts; grouping concepts into categories; formation of a theory. In the open coding stage, we analyze the text and identify any interesting phenomena in the data. Normally each unique phenomenon is given a distinctive name or code. The procedure and methods for identifying coding items are discussed in section 11.5.2. In the second stage, collections of codes that describe similar contents are grouped together to form higher level "concepts." In the third stage, broader groups of similar concepts are identified to form "categories" and there is a detailed interpretation of each category. In this process, we are constantly searching for and refining the conceptual construct that may explain the relationship between the concepts and categories (Glaser, 1978). In the last stage, theory formulation, we aim at creating inferential and predictive statements about the phenomena recorded in the data. — Jonathan Lazar

I have noticed that a lot of literary critics are bothered by the mixing of genres; indeed, some of them are so easily offended in this regard that they experience distress when faced with trifles like the use in a passage of fiction of concepts of theory (as if there were some fundamental difference between stories of people, animals, plants and objects on the one hand and stories of concepts on the other). What a torture it would be for them to read the island's Book, in which it is common for a lyrical passage to give way to several pages of description related in chemical formulae! — Michal Ajvaz

This irrelevance of molecular arrangements for macroscopic results has given rise to the tendency to confine physics and chemistry to the study of homogeneous systems as well as homogeneous classes. In statistical mechanics a great deal of labor is in fact spent on showing that homogeneous systems and homogeneous classes are closely related and to a considerable extent interchangeable concepts of theoretical analysis (Gibbs theory). Naturally, this is not an accident. The methods of physics and chemistry are ideally suited for dealing with homogeneous classes with their interchangeable components. But experience shows that the objects of biology are radically inhomogeneous both as systems (structurally) and as classes (generically). Therefore, the method of biology and, consequently, its results will differ widely from the method and results of physical science. — Walter M. Elsasser

Despite my deep unease about animal advocates working for things we don't want and asking for changes we don't believe in, I am not an "abolitionist." First, the abolition of animal slavery will no more end speciesism by itself than the abolition of American slavery ended racism. To change the world, I think we should aim higher. Second, I'm increasingly convinced that no matter who uses the term, it hides a slur. When used to refer to others, it connotes zealotry and obstructionism, and when taken as self-definition, it is seen as an attack by anyone who does not apply it to herself. Yes, it's a highly defensible moral philosophy, right up there with Peter Singer's application of Utilitarianism to animal liberation, and Tom Regan's Theory of Rights, but like those other intellectual concepts, it's useful only so far as it engenders right action. — Sarahjane Blum

Someone asked me very recently why I have 8 million views on TED - "your work resonates, what are you doing?" What I think my contribution is, what I do well, is I name experiences that are very universal that no one really talks about. That's the researcher in me; that's really part of being a grounded theory researcher - putting names to concepts and experiences that people have. That's the researcher part. — Brene Brown
