The patient, treated on the fashionable theory, sometimes gets well in spite of the medicine.

Such is professional jealousy; a scientist will never show any kindness for a theory which he did not start himself.

The error in positivism is that it takes as its standard of truth the contingently given division of labor, that between the science and social praxis as well as that within science itself, and allows no theory that could reveal the division of labor to be itself derivative and mediated and thus strip it of its false authority.
Theodor W. Adorno

Freedom is not merely a word or an abstract theory, but the most effective instrument for advancing the welfare of man.

Whether you can observe a thing or not depends on the theory which you use. It is the theory which decides what can be observed.

A physical theory is not an explanation. It is a system of mathematical propositions, deduced from a small number of principles, which aim... to represent as simply, as completely, and as exactly as possible a group of experimental laws.

It might be that the biggest division in the world isn't men and women but folks who like cats and folks who like dogs" - (L.T.'s Theory of Pets)

It is said that this manifesto is more than a theory, that it was an incitement. Every idea is an incitement.

I have a theory, too, that the best and only answer to a smear or to an honest misunderstanding of the facts is to tell the truth

To allow opposition by speech seems to indicate that you think the speech impotent, as when a man says that he has squared the circle, or that you do not care whole-heartedly for the result, or that you doubt either your power or your premises. But when men have realized that time has upset many fighting faiths, they may come to believe even more than they believe the very foundations of their own conduct that the ultimate good desired is better reached by free trade in ideas —that the best test of truth is the power of the thought to get itself accepted in the competition of the market, and that truth is the only ground upon which their wishes safely can be carried out. That at any rate is the theory of our Constitution.
Oliver Wendell Holmes, Jr.

Under the present dispensation, the great majority of factories are little despotisms, benevolent in some cases, malevolent in others. Even where benevolence prevails, passive obedience is demanded by the workers, who are ruled by overseers, not of their own election, but appointed from above. In theory they may be the subjects of a democratic state; but in practice they spend the whole of their working lives as the subjects of a petty tyrant.
Aldous Huxley

We obtain our concept of the unconscious, therefore, from the theory of repression … We see, however that we have two kinds of unconscious — that which is latent but capable of becoming conscious, and that which is repressed and not capable of becoming conscious in the ordinary way.

I can still recall vividly how Freud said to me, "My dear Jung, promise me never to abandon the sexual theory. That is the most essential thing of all. You see, we must make a dogma of it, an unshakable bulwark"... In some astonishment I asked him, "A bulwark-against what?" To which he replied, "Against the black tide of mud"-and here he hesitated for a moment, then added of occultism.

With all of its false assumptions and evil methods, communism grew as a protest against the hardships of the underprivileged. Communism in theory emphasized a classless society, and a concern for social justice, though the world knows from sad experience that in practice it created new classes and a new lexicon of injustice.
Martin Luther King, Jr.

Each time new experiments are observed to agree with the predictions the theory survives, and our confidence in it is increased; but if ever a new observation is found to disagree, we have to abandon or modify the theory.

To test a perfect theory with imperfect instruments did not impress the Greek philosophers as a valid way to gain knowledge.

I believe that faith is a precursor of all our ideas. Without faith, there never could have evolved hypothesis, theory, science or mathematics. I believe that faith is an extension of the mind. It is the key that negates the impossible. To deny faith is to refute oneself and the spirit that generates all our creative forces. My faith is in the unknown, in all that we do not understand by reason; I believe that what is beyond our comprehension is a simple fact in other dimensions, and that in the realm of the unknown there is an infinite power for good.

It is well said, then, that it is by doing just acts that the just man is produced, and by doing temperate acts the temperate man; without doing these no one would have even a prospect of becoming good. But most people do not do these, but take refuge in theory and think they are being philosophers and will become good in this way, behaving somewhat like patients who listen attentively to their doctors, but do none of the things they are ordered to do.

By an application of the theory of relativity to the taste of readers, today in Germany I am called a German man of science, and in England I am represented as a Swiss Jew. If I come to be represented as a bête noire, the descriptions will be reversed, and I shall become a Swiss Jew for the Germans and a German man of science for the English!

A theory can be proved by experiment; but no path leads from experiment to the birth of a theory.

A Constitution is not intended to embody a particular economic theory... It is made for people of fundamentally differing views, and the accident of our finding certain opinions natural and familiar, or novel, and even shocking, ought not to conclude our judgment upon the question whether statutes embodying them conflict with the Constitution of the United States.
Oliver Wendell Holmes, Jr.

The theory of relativity does, however, force us to change fundamentally our ideas of space and time. We must accept that time is not completely separate from and independent of space, but is combined with it to form an object called space-time.

I've a theory that one can always get anything one wants if one will pay the price. And do you know what the price is, nine times out of ten? Compromise. A beastly thing, compromise, but it steals upon you as you near middle age. It's stealing upon me now. To get the woman I want I'd — I'd even take up regular work.
