I don't mean to deny that the evidence is in some ways very strong in favor of your theory, I only wish to point out that there are other theories possible.

Me, I am convinced it is the truth, said M. Bouc, becoming more and more enamoured of his theory.

In theory I could run my business perfectly, and then run the country perfectly. And there's never been a case like this where somebody's had, like, if you look at other people of wealth, they didn't have this kind of asset and this kind of wealth, frankly. It's just a different thing.

I was sitting in a chair in the patent office in Bern when all of a sudden a thought occurred to me: 'If a person falls freely he will not feel his own weight.' I was startled. This simple thought made a deep impression on me. It impelled me toward a theory of gravitation.

Those who are in love with practice without knowledge are like the sailor who gets into a ship without rudder or compass and who never can be certain whether he is going. Practice must always be founded on sound theory, and to this Perspective is the guide and the gateway; and without this nothing can be done well in the matter of drawing.

All our science is just a cookery book, with an orthodox theory of cooking that nobody's allowed to question, and a list of recipes that mustn't be added to except by special permission from the head cook.

Laws which are consistent in theory often prove chaotic in practice.

It should be remembered, as an axiom of eternal truth in politics, that whatever power in any government is independent, is absolute also; in theory only, at first, while the spirit of the people is up, but in practice, as fast as that relaxes. Independence can be trusted nowhere but with the people in mass. They are inherently independent of all but moral law.

How is Marxist-Leninist theory to be linked with the practice of the Chinese revolution? To use a common expression, it is by "shooting the arrow at the target". As the arrow is to the target, so is Marxism-Leninism to the Chinese revolution. Some comrades, however, are "shooting without a target", shooting at random, and such people are liable to harm the revolution.

All science has one aim, namely, to find a theory of nature.

This mental activity, at first involuntary under the pressure of illness and suffering, gradually became second nature and led me finally to recognize that I was but an automaton devoid of free will in thought and action and merely responsible to the forces of the environment. Our bodies are of such complexity of structure, the motions we perform are so numerous and involved and the external impressions on our sense organs to such a degree delicate and elusive, that it is hard for the average person to grasp this fact. Yet nothing is more convincing to the trained investigator than the mechanistic theory of life which had been, in a measure, understood and propounded by Descartes three hundred years ago.

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

Don Basilio was a forbidding-looking man with a bushy moustache who did not suffer fools and who subscribed to the theory that the liberal use of adverbs and adjectives was the mark of a pervert or someone with a vitamin deficiency.

The notion that inspiration is something that happened thousands of years ago, and was then finished and done with... the theory that God retired from business at that period and has not been heard from since, is as silly as it is blasphemous.

There may be no ultimate theory, and even if there is, we may not find it. But it is surely better to strive for a complete understanding than to despair of the human mind.

It is only theory that makes men completely incautious.

Criticism - however valid or intellectually engaging - tends to get in the way of a writer who has anything personal to say. A tightrope walker may require practice, but if he starts a theory of equilibrium he will lose grace (and probably fall off).

A truly rational theory would allow us to deduce the elementary particles (electron, etc.) and not be forced to state them a priori.

Now I'm not saying that Keynes was right about everything, that we should treat The General Theory as a sort of secular bible - the way that Marxists treat Das Kapital. But the essential truth of Keynes's big idea - that even the most productive economy can fail if consumers and investors spend too little, that the pursuit of sound money and balanced budgets is sometimes (not always!) folly rather than wisdom - is as evident in today's world as it was in the 1930s. And in these dangerous days, we ignore or reject that idea at the world economy's peril.

Quantum theory was split up into dialects. Different people describe the same experiences in remarkably different languages. This is confusing even to physicists.

According to the disease theory of delinquency, the arsonist has 'pyromania,' the thief 'kleptomania,' and Bill Clinton is not promiscuous, but a 'sex-addict.'

A work on tidal theory... led me to Lagrange's Mécanique analytique and thereby I returned to those ideas of analysis. All the developments in that work were transformed through the principles of the new analysis in such a simple way that the calculations often came out more than ten times shorter than in Lagrange's work.

Religion is not simply a theory, it is a higher life, of which morality is an integral part - a life devoted to the worship of the good and the true, for God, the absolute, is the supreme source of all perfection.

At the Everyman Cinema there is a season of Satyajit Ray. He watches the Apu trilogy on successive nights in a state of rapt absorption. In Apu's bitter, trapped mother, his engaging, feckless father he recognizes, with a pang of guilt, his own parents. But it is the music above all that grips him, dizzyingly complex interplays between drums and stringed instruments, long arias on the flute whose scale or mode — he does not know enough about music theory to be sure which — catches at his heart, sending him into a mood of sensual melancholy that last long after the film has ended.
