Quotes on Theory

The passion for playing chess is one of the most unaccountable in the world. It slaps the theory of natural selection in the face. It is the most absorbing of occupations. The least satisfying of desires. A nameless excrescence upon life. It annihilates a man. You have, let us say, a promising politician, a rising artist that you wish to destroy. Dagger or bomb are archaic and unreliable - but teach him, inoculate him with chess.

It is true that the grasping of truth is not possible without empirical basis. However, the deeper we penetrate and the more extensive and embracing our theories become the less empirical knowledge is needed to determine those theories.

According to the estimate of a prominent advertising firm, above 90 per cent, of the earning capacity of the prominent nostrums is represented by their advertising. And all this advertising is based on the well-proven theory of the public's pitiable ignorance and gullibility in the vitally important matter of health.

Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king... its exponents are brilliant men but they are metaphysicists rather than scientists.

Evolution is the creation-myth of our age. By telling us our origin it shapes our views of what we are. It influences not just our thought, but our feelings and actions too, in a way which goes far beyond its official function as a biological theory.

A theory of motivation is defective if it renders intelligible behaviour which is not intelligible.

As soon as we notice that certain types of events 'like' to cluster together at certain times, we begin to understand the Chinese, whose theories of medicine, philosophy, and even building are based on a 'science' of meaningful coincidences.

This theory [the oxygen theory] is not as I have heard it described, that of the French chemists, it is mine (elle est la mienne); it is a property which I claim from my contemporaries and from posterity.

When the province of physical theory was extended to encompass microscopic phenomena through the creation of quantum mechanics, the concept of consciousness came to the fore again. It was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.

I try to see each new season as a new challenge because I have a new team to work with, new opponents to encounter, and often new ideas and theories to try

You didn't see me on television, you didn't see news stories about me. The kind of role that I tried to play was to pick up pieces or put together pieces out of which I hoped organization might come. My theory is, strong people don't need strong leaders.

No philosophical theory which I have yet come across is a radical improvement on the words of Genesis, that 'In the beginning God made Heaven and Earth'.

It is always noteworthy that all those who seriously study this science [the theory of numbers] conceive a sort of passion for it.

[In mathematics] There are two kinds of mistakes. There are fatal mistakes that destroy a theory, but there are also contingent ones, which are useful in testing the stability of a theory.

When an investigator has developed a formula which gives a complete representation of the phenomena within a certain range, he may be prone to satisfaction. Would it not be wiser if he should say 'Foiled again! I can find out no more about Nature along this line.'

We can invent as many theories we like, and any one of them can be made to fit the facts. But that theory is always preferred which makes the fewest number of assumptions.

The theoretical idea ... does not arise apart from and independent of experience; nor can it be derived from experience by a purely logical procedure. It is produced by a creative act. Once a theoretical idea has been acquired, one does well to hold fast to it until it leads to an untenable conclusion.

The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle.

That is the way of the scientist. He will spend thirty years in building up a mountain range of facts with the intent to prove a certain theory; then he is so happy with his achievement that as a rule he overlooks the main chief fact of all-that all his accumulation proves an entirely different thing.

Such an atmosphere is un-American, the most un-American thing we have to contend with today. It is the climate of a totalitarian country in which scientists are expected to change their theories to match changes in the police state's propaganda line.

Scientists have odious manners, except when you prop up their theory; then you can borrow money off them.
