I worked out an anarchistic theory that all government is evil, that the punishment always does more harm than the crime and the people can be trusted to behave decently if you will only let them alone.

Since others have explained my theory, I can no longer understand it myself.

Albert Einstein

My policies are based not on some economics theory, but on things I and millions like me were brought up with: an honest day's work for an honest day's pay; live within your means; put by a nest egg for a rainy day; pay your bills on time; support the police.

Margaret Thatcher

If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. But I can find out no such case.

My faith in the reliability of the theory still fluctuates... Thus, if not all systems of equations of the theory... admit transformations other than linear ones, then the theory contradicts its own starting point and all is up in the air.

Albert Einstein

Do you see this egg? With this you can topple every theological theory, every church or temple in the world. What is it, this egg, before the seed is introduced into it? An insentient mass. And after the seed has been introduced to into it? What is it then? An insentient mass. For what is the seed itself other than a crude and inanimate fluid? How is this mass to make a transition to a different structure, to sentience, to life? Through heat. And what will produce that heat in it? Motion.

If we do discover a complete theory, it should in time be understandable in broad principle by everyone, not just a few scientists. Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason — for then we would know the mind of God.

Stephen Hawking

The first theory is that if we make the rich richer, somehow they will let a part of their prosperity trickle down to the rest of us. The second theory was the theory that if we make the average of mankind comfortable and secure, their prosperity will rise upward through the ranks.

Franklin D. Roosevelt

There is no great harm in the theorist who makes up a new theory to fit a new event. But the theorist who starts with a false theory and then sees everything as making it come true is the most dangerous enemy of human reason.

G. K. Chesterton

How it happened that I in particular discovered the relativity theory, it seemed to lie in the following circumstance. The normal adult never bothers his head about space-time problems. Everything there is to be thought about it, in his opinion, has already been done in early childhood. I, on the contrary, developed so slowly that I only began to wonder about space and time when I was already grown up. In consequence I probed deeper into the problem than an ordinary child would have done.

Albert Einstein

To think historically is almost the same thing now as if in all ages history had been made according to theory.

Friedrich Nietzsche

Mr. Darwin begs me to say that he receives so many letters that he cannot answer them all. He considers that the theory of evolution is quite compatible with the belief in a God; but that you must remember that different persons have different definitions of what they mean by God.

Only the defeat of the proletariat in Germany in 1923 gave the decisive push to the creation of Stalin's theory of national socialism: the downward curve of the revolution gave rise to Stalinism, not to the theory of the permanent revolution, which was first formulated by me in 1905. This theory is not bound to a definite calendar of revolutionary events; it only reveals the world-wide interdependence of the revolutionary process.

The sole purpose of physical theory is to provide a representation and classification of experimental laws; the only test permitting us to judge a physical theory and pronounce it good or bad is the comparison between the consequences of this theory and the experimental laws it has to represent and classify.

Arthur Conan Doyle

The materialist theory of history, that all politics and ethics are the expression of economics, is a very simple fallacy indeed. It consists simply of confusing the necessary conditions of life with the normal preoccupations of life, that are quite a different thing. It is like saying that because a man can only walk about on two legs, therefore he never walks about except to buy shoes and stockings.

G. K. Chesterton

Control by experiment... is, of course, an essential prerequisite of the validity of any theory. But one can't possibly test everything. That is why I am so interested in your remarks about simplicity. Still, I should never claim that I really understood what is meant by the simplicity of natural laws.

Albert Einstein

Philosophy … should not imagine that specialized work in epistemological theory, or whatever else prides itself on being research, is actually philosophy. Yet a philosophy forswearing all of that must in the end be irreconcilably at odds with the dominant consciousness. Nothing else raises it above the suspicion of apologetics. Philosophy that satisfies its own intention, and does not childishly skip behind its own history and the real one, has its lifeblood in the resistance against the common practices of today and what they serve, against the justification of what happens to be the case.

Theodor W. Adorno

We wish to fill our culture once more with the spirit of Christianity - but not only in theory.

We must respect the other fellow's religion, but only in the sense and to the extent that we accept his theory that his wife is beautiful and his children smart.

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.

Hermann Grassmann

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.

This article [entitled A framework for the comparative analysis of organizations], was one of three independent statements in 1967 of what came to be called "contingency theory." It held that the structure of an organization depends upon (is 'contingent' upon) the kind of task performed, rather than upon some universal principles that apply to all organizations. The notion was in the wind at the time.

The mathematician may be compared to a designer of garments, who is utterly oblivious of the creatures whom his garments may fit.... The conic sections, invented in an attempt to solve the problem of doubling the alter of an oracle, ended by becoming the orbits followed by the planets... The imaginary magnitudes invented by Cardan and Bombelli describe... the characteristic features of alternating currents. The absolute differential calculus, which originated as a fantasy of Reimann, became the mathematical model for the theory of Relativity. And the matrices which were a complete abstraction in the days of Cayley and Sylvester appear admirably adapted to the... quantum of the atom.

Myrdalian ex ante language would have saved the General Theory from describing the flow of investment and the flow of saving as identically, tautologically equal, and within the same discourse, treating their equality as a condition which may, or not, be fulfilled

G. L. S. Shackle

Lacanian theory must be understood as a kind of slave morality.
