Top 1200 Systems Theory Quotes & Sayings

I didn't know so well chess theory, the theory of chess openings. And so, of course I knew the theory, but not on the level of the best players, so this was my... this was always my weakness.

Human beings are pattern-seeking animals who will prefer even a bad theory or a conspiracy theory to no theory at all.

I have been a systems engineer, systems administrator, a senior adviser for the Central Intelligence Agency, a solutions consultant and a telecommunications information systems officer.

Catastrophe Theory is-quite likely-the first coherent attempt (since Aristotelian logic) to give a theory on analogy. When narrow-minded scientists object to Catastrophe Theory that it gives no more than analogies, or metaphors, they do not realise that they are stating the proper aim of Catastrophe Theory, which is to classify all possible types of analogous situations.

Organize around business functions, not people. Build systems within each business function. Let systems run the business and people run the systems. People come and go but the systems remain constant.

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

There is a new venue for theory, necessarily impure, where it emerges in and as the very event of cultural translation. This is not the displacement of theory by historicism, nor a simple historicization of theory that exposes the contingent limits of its more generalizable claims.

The driver of the power of intelligent systems is the knowledge the systems have about their universe of discourse, not the sophistication of the reasoning process the systems employ.

Is evolution a theory, a system, or an hypothesis? It is much more: it is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforward if they are to be thinkable and true.

I had two passions when I was a child. First was to learn about Einstein's theory and help to complete his dream of a unified theory of everything. That's my day job. I work in something called string theory. I'm one of the founders of the subject. We hope to complete Einstein's dream of a theory of everything.

When we meet a fact which contradicts a prevailing theory, we must accept the fact and abandon the theory, even when the theory is supported by great names and generally accepted.

If the theory accurately predicts what they [scientists] see, it confirms that it's a good theory. If they see something that the theory didn't lead them to believe, that's what Thomas Kuhn calls an anomaly. The anomaly requires a revised theory - and you just keep going through the cycle, making a better theory.

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.

People have a hard time accepting free-market economics for the same reason they have a hard time accepting evolution: it is counterintuitive. Life looks intelligently designed, so our natural inclination is to infer that there must be an intelligent designer--a God. Similarly, the economy looks designed, so our natural inclination is to infer that we need a designer--a government. In fact, emergence and complexity theory explains how the principles of self-organization and emergence cause complex systems to arise from simple systems without a top-down designer.

Theory is worth but little, unless it can explain its own phenomena, and it must effect this without contradicting itself; therefore, the facts are sometimes assimilated to the theory, rather than the theory to the facts.

The only real argument for monolithic systems was performance, and there is now enough evidence showing that microkernel systems can be just as fast as monolithic systems.

I believe without exception that theory follows practice. Whenever there is a conflict between theory and practice, theory is wrong. As far as I'm concerned, we make theories for what people have done.

There are two theories. There's one theory that Barack Obama wants to destroy the country and create a socialistic country. There is that theory, and I've read a lot. This isn't necessarily my theory. I personally think they're incompetent.

I hope we find evidence of dark matter in the lab and in outer space. This would go a long way to proving the correctness of string theory, which is what I do for a living. That is my day job. So string theory is a potentially experimentally verifiable theory.

If you're a physicist, for heaven's sake, and here is the experiment, and you have a theory, and the theory doesn't agree with the experiment, then you have to cut out the theory. You were wrong with the theory.

After preliminary work by a number of other distinguished mathematicians and economists, game theory as a systematic theory started with von Neumann and Morgenstern's book, 'Theory of Games and Economic Behavior,' published in 1944.

Theory without practice is of little value, whereas practice is the proof of theory.Theory is the knowledge, practice the ability.

Our ancient yogis and sages were not just medical healers, but systems scientists and systems engineers, who saw the body and the universe as an interconnected engineering system, a system of systems that are governed by fundamental engineering systems principles.

My hacking involved pretty much exploring computer systems and obtaining access to the source code of telecommunication systems and computer operating systems, because my goal was to learn all I can about security vulnerabilities within these systems.

The canary bird in the coal mine theory of the arts: artists should be treasured as alarm systems.

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

The theory of chaos and theory of fractals are separate, but have very strong intersections. That is one part of chaos theory is geometrically expressed by fractal shapes.

All economies are structured differently - the tax systems, the regulatory systems, the federal systems - and that is as true of Australia and the United States as it is of Australia and Germany and the U.K.

The development of mathematics toward greater precision has led, as is well known, to the formalization of large tracts of it, so that one can prove any theorem using nothing but a few mechanical rules... One might therefore conjecture that these axioms and rules of inference are sufficient to decide any mathematical question that can at all be formally expressed in these systems. It will be shown below that this is not the case, that on the contrary there are in the two systems mentioned relatively simple problems in the theory of integers that cannot be decided on the basis of the axioms.

Modern dynamical systems theory has a relatively short history. It begins with Poincare (of course)... [to whom] a global understanding of the gross behavior of all solutions of the system was more important than the local behavior of particular, analytically-precise solutions.

Our civilization is facing a radical, imminent mass change. The alternative to the hierarchical power structure is based on mutual aid and group consensus. As hackers we can learn these systems, manipulate these systems, and shut down these systems if we need to.

Legal reform has significant dangers: changing only the window-dressing of harmful systems but leaving the violence of the systems in tact, failing to provide actual relief for those facing the worst conditions, and legitimizing or expanding systems of harm.

I really don't like art where you need to know so much theory to understand. If the theory is removed, it doesn't do anything. That means that this work is an illustration of theory, and I don't believe in the power of the work itself.

The more evolutionary theory gets called an atheistic theory, the greater the risk that it will lose its place in public school biology courses in the United States. If the theory is thought of in this way, one should not be surprised if a judge at some point decides that teaching evolutionary theory violates the Constitutional principle of neutrality with respect to religion.

Creationists reject Darwin's theory of evolution on the grounds that it is "just a theory". This is a valid criticism: evolution is indeed merely "a theory", albeit one with ten billion times more credence than the theory of creationism - although, to be fair, the theory of creationism is more than just a theory. It's also a fairy story. And children love fairy stories, which is presumably why so many creationists are keen to have their whimsical gibberish taught in schools.

The theory of natural selection is the centerpiece of The Origin of Species and of evolutionary theory. It is this theory that accounts for the adaptations of organisms, those innumerable features that so wonderfully equip them for survival and reproduction; it is this theory that accounts for the divergence of species from common ancestors and thus for the endless diversity of life. Natural selection is a simple concept, but it is perhaps the most important idea in biology.

Evolution ... is really two theories, the vague theory and the precise theory. The vague theory has been abundantly proved.... The precise theory has never been proved at all. However, like relativity, it is accepted on faith.... On getting down to actual details, difficulties begin.

Indeed, this epistemological theory of the relation between theory and experiment differs sharply from the epistemological theory of naive falsificationism.

I think it's a theory... the theory of evolution and I don't accept it as a theory.

Moral theory develops from the divine command theory of medieval Christian philosophy, mixed up with a bit of ancient pagan virtue theory, to the purely secular moral sentiment and interpersonal reaction theories of Smith and Hume, to Kant's attempt to restore command theory but with something supersensible in the individual rather than God as the source of authority.

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.

Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory.

I think it laughable, frankly, that the physics community comes up with a theory for everything. There isn't one theory for everything. There is not one explanation. We may eventually have several theories that can tie things together nicely but there is not a single theory of everything.

We are losing our living systems, social systems, cultural systems, governing systems, stability, and our constitutional health, and we're surrendering it all at the same time.

Around the world there are certain marital systems, certain physical systems, political systems, social systems, and all those things are kind of turned on their head but represented in various ways within "The Lobster."

A cardinal principle in systems theory is that all parties that have a stake in a system should be represented in its management.

People crave predictability, and when you design and use systems, you give people predictability. More importantly, when you build systems, they can help you orchestrate, and orchestration helps you create the habits that continuously improve the systems!

The aim of academic trade theory is to tell students, "Look at the model, not at how nations actually develop." So of all the branches of economic theory, trade theory is the most wrongheaded.

As my colleague, the physical chemist Peter Atkins, puts it, we must be equally agnostic about the theory that there is a teapot in orbrit around the planet Pluto. We can't disprove it. But that doesn't mean the theory that there is a teapot is on level terms with the theory that there isn't.

Do not be idolatrous about or bound to any doctrine, theory, or ideology, even Buddhist ones. All systems of thought are guiding means; they are not absolute truth.

I don't think about a theory of everything when I do my research. And even if we knew the ultimate underlying theory, how are you going to explain the fact that we're sitting here? Solving string theory won't tell us how humanity was born.

It is easy to obtain confirmations, or verifications, for nearly every theory-if we look for confirmations. Confirmations should count only if they are the result of risky predictions... A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice. Every genuine test of a theory is an attempt to falsify it, or refute it.

The only debatable issue, it seems to me, is whether it is more ridiculous to turn to experts in social theory for general well-confirmed propositions, or to the specialists in the great religions and philosophical systems for insights into fundamental human values.

We are not pursuing research to develop ABM space systems. There are studies to improve systems of warning against a missile attack, communications and navigation systems and to develop ground-based ABM defences.

There is a distinction, but no opposition, between theory and practice. Each to a certain extent supposes the other. Theory is dependent on practice; practice must have preceded theory.

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.

A major attack on our cyber systems could shut down our critical infrastructure - financial systems, communications systems, electric grids, power plants, water treatment centers, transportation systems and refineries - that allows us to run our economy and protect the safety of Americans.

The most important single thing about string theory is that it's a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That's big news.

Creationists have long held that evolutionary theory is atheistic; defenders of the theory do the theory no favor when they agree.

I believe that the best way to create good living conditions for any animal, whether it's a captive animal living in a zoo, a farm animal or a pet, is to base animal welfare programs on the core emotion systems in the brain. My theory is that the environment animals live in should activate their positive emotions as much as possible, and not activate their negative emotions any more than necessary. If we get the animal's emotions rights, we will have fewer problem behaviors... All animals and people have the same core emotion systems in the brain.
