There are a lot of theories about Shakespeare.

Theories have nothing to do with life.

I now want to tell three stories about advances in twentieth-century physics. A curious fact emerges in these tales: time and again physicists have been guided by their sense of beauty not only in developing new theories but even in judging the validity of physical theories once they are developed. Simplicity is part of what I mean by beauty, but it is a simplicity of ideas, not simplicity of a mechanical sort that can be measured by counting equations or symbols.

Skills make you rich, not theories.

As to ethics, unfortunately, we are still at sea. We never did have any popular base for what little ethics we knew, except the religious theories, and now that our faith is shaken in those theories we cannot account for ethics at all. It is no wonder we behave badly, we are literally ignorant of the laws of ethics, which is the simplest of sciences, the most necessary, the most continuously needed. The childish misconduct of our 'revolted youth' is quite equaled by that of older people, and neither young nor old seem to have any understanding of the reasons why conduct is 'good' or 'bad.

The first step toward the management of disease was replacement of demon theories and humours theories by the germ theory. That very step, the beginning of hope, in itself dashed all hopes of magical solutions. It told workers that progress would be made stepwise, at great effort, and that a persistent, unremitting care would have to be paid to a discipline of cleanliness. So it is with software engineering today.

People love conspiracy theories.

History has got a lot to do with unique circumstances under certain particular cases and grand theories will always find counter cases. I don't think that people whose expertise lies in one thing should try to make grand theories about something (a) where it's very hard to get the evidence to prove that you're right and (b) where it's much too easy to make up stories that seem right.

As a rule we disbelieve all the facts and theories for which we have no use.

Scientists tend to risk theories they admire

Goals and objectives are based on theories and foundations.

Newton's theory is not 'not right', it just does not cover all distances. Contrary to popular belief, theories in science are not proven wrong, they are just replaced by more complete and convenient theories. To sound provocative, even the geocentric theory was never "proven" wrong, it is just not as convenient as the heliocentric theory, since it requires endless epicycles.

Let us leave theories there and return to here's hear.

There’s a few conspiracy theories that I believe in, but not too many.

Literary theories will not make a writer write.

We are all trained to be data driven people, but no hard data exist about the future. Therefore, the only way to look into the future with any degree of accuracy is to use theory, statements of what causes what and why. If executives have the right theories in their heads, they can very quickly interpret market developments. They can identify what matters and why, and act accordingly. So we suggest decision-makers should start by gaining a deep understanding of the relevant collection of theories, and then be alert for signals that indicate certain types of developments.

We see the world in terms of our theories.

My children, the secret of religion lies not in theories but in practice.

Evolution is a theory in a special philosophical sense of science, but in terms of ordinary laymen's use of language, it's a fact, .. Evolution is a fact in the same sense that it's a fact that the Earth is round and not flat, [that] the Earth goes round the Sun. Both those are also theories, but they're theories that have never been disproved and never will be disproved.

Conspiracy theories are the refuge of the disempowered.

There's a few conspiracy theories that I believe in, but not too many.

Let's develop theories, patiently and honestly thinking them out, in order to promptly act against them – acting and justifying our actions with new theories that condemn them. Let's cut a path in life and then go immediately against that path. Let's adopt all the poses and gestures of something we aren't and don't even wish to be, and don't even wish to taken for being.

It is ... a sign of the times-though our brothers of physics and chemistry may smile to hear me say so-that biology is now a science in which theories can be devised: theories which lead to predictions and predictions which sometimes turn out to be correct. These facts confirm me in a belief I hold most passionately-that biology is the heir of all the sciences.

Biochemists and biologists who adhere blindly to the Darwinism theory search for results that will be in agreement with their theories and consequently orient their research in a given direction, whether it be in the field of ecology, ethology, sociology, demography (dynamics of populations), genetics (so-called evolutionary genetics), or paleontology. This intrusion of theories has unfortunate results: it deprives observations and experiments of their objectivity, makes them biased, and, moreover, creates false problems.

Theories of history used to be supernatural: the divine ruled time; the hand of God, a special providence, lay behind the fall of each sparrow. If the present differed from the past, it was usually worse: supernatural theories of history tend to involve decline, a fall from grace, the loss of God's favor, corruption.

Theories are not so much wrong as incomplete

Generally speaking, geologists seem to have been much more intent on making little worlds of their own, than in examining the crust of that which they inhabit. It would be much more desirable that facts should be placed in the foreground and theories in the distance, than that theories should be brought forward at the expense of facts. So that, in after times, when the speculations of the present day shall have passed away, from a greater accumulation of information, the facts may be readily seized and converted to account.

When you're operating on uninvestigated theories of what's going on and you aren't even aware of it, you're in what I call "the dream." Often the dream becomes troubling; sometimes it even turns into a nightmare. At times like these, you may want to test the truth of your theories by doing The Work on them. The Work always leaves you with less of your uncomfortable story. Who would you be without it? How much of your world is made up of unexamined stories? You'll never know until you inquire.

Theories are patterns without value. What counts is action.

Perhaps generations of students of human evolution, including myself, have been flailing about in the dark; that our data base is too sparse, too slippery, for it to be able to mold our theories. Rather the theories are more statements about us and ideology than about the past. Paleontology reveals more about how humans view themselves than it does about how humans came about, but that is heresy.

Theories pass. The frog remains.

All theories are legitimate, no matter. What matters is what you do with them.

Theories are just fantasies. And they change.

Yet the widespread planetary theories, advanced by Ptolemy and most other astronomers, although consistent with the numerical data, seemed likewise to present no small difficulty. For these theories were not adequate unless they also conceived certain equalizing circles, which made the planet appear to move at all times with uniform velocity neither on its deferent sphere nor about its own epicycle's center.

Progress is achieved by exchanging our theories for new ones which go further than the old, until we find one based on a larger number of facts. ... Theories are only hypotheses, verified by more or less numerous facts. Those verified by the most facts are the best, but even then they are never final, never to be absolutely believed.

The Church demonstrated the falsity and folly of Darwin's theories by showing that they contradicted the Mosaic account of creation, and now that the theories of Darwin having been fairly established, the Church says that the Mosaic account is true because it is in harmony with Darwin. Now, if it should turn out that Darwin was mistaken, what then?

Theories can be based on any assumptions, however bizarre.

Many theories of the ancient world seem terribly childish today, a hodge-podge of fables and false comparisons.But our theories will seem childish five-hundred years from now.Every theory is based on some analogy, and sooner or later the theory fails because the analogy turns out to be false. A theory in its day helps to solve the problems of the day.

Strong and convincing art has never arisen from theories.

There are many examples of old, incorrect theories that stubbornly persisted, sustained only by the prestige of foolish but well-connected scientists... Many of these theories have been killed off only when some decisive experiment exposed their incorrectness... Thus the yeoman work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest.

I have made some headway in addressing these questions, however, and succeeded in explaining how it is that the category of knowledge might play an important role in empirical theories. To the extent that talk of knowledge can be shown to play an explanatory role in such theories, the analogy I wish to make with paradigm natural kinds such as acids and aluminum starts to make a good deal of sense. This is, of course, connected with the issue of the role of intuitions in philosophy.

Theories are private property, but truth is common stock.

I have a theory that theories are destructive.

Theories crumble, but good observations never fade.
