Quotes on Theory

Progress is Providence without God. That is, it is a theory that everything has always perpetually gone right by accident. It is a sort of atheistic optimism, based on an everlasting coincidence far more miraculous than a miracle.

Well-established theories collapse under the weight of new facts and observations which cannot be explained, and then accumulate to the point where the once useful theory is clearly obsolete.

There's this really awesome theory of human motivation - that human beings all want three things. One is to be competent, one is to belong, and one is be free, as in to have choice: to not be told what to do but to choose what to do.

You do not take a person who, for years, has been hobbled by chains and liberate him, bring him up to the starting line of a race and then say, "you are free to compete with all the others," and still justly believe that you have been completely fair. We seek not just legal equity but human ability, not just equality as a right and a theory but equality as a fact and equality as a result.

Let the writer take up surgery or bricklaying if he is interested in technique. There is no mechanical way to get the writing done, no shortcut. The young writer would be a fool to follow a theory. Teach yourself by your own mistakes; people learn only by error. The good artist believes that nobody is good enough to give him advice. He has supreme vanity. No matter how much he admires the old writer, he wants to beat him.

Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point particle is replaced by a string, which is more spread out.

So long as we use a certain language, all questions that we can ask will have to be formulated in it and will thereby confirm the theory of the universe which is implied in the vocabulary and structure of the language.

Our tradition of political thought had its definite beginning in the teachings of Plato and Aristotle. I believe it came to a no less definite end in the theories of Karl Marx.

Evolution is a fact. It is the best explanation of what is known from observations. It's a theory as powerful as the theory of gravity.

No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.

To produce a really good biological theory one must try to see through the clutter produced by evolution to the basic mechanisms lying beneath them, realizing that they are likely to be overlaid by other, secondary mechanisms. What seems to physicists to be a hopelessly complicated process may have been what nature found simplest, because nature could only build on what was already there.

Quantum mechanics is certainly imposing. But an inner voice tells me that this is not yet the real thing. The theory says a lot, but does not bring us any closer to the secrets of the "Old One." I, at any rate, am convinced that He is not playing at dice.

The sun had, in the meanwhile, sunk behind the Ettersberg. We felt in the wood the chill of the evening, and drove all the quicker to Wiemar, and to Goethe's house. Goethe urged me to go in with him for a while, and I did so. He was in an extremely engaging mood. He talked a great deal about his theory of colors, and of his obstinate opponents; remarking that he was sure that he had done something in this science.

In life, people tend to wait for good things to come to them. And by waiting, they miss out. Usually, what you wish for doesn't fall in your lap; it falls somewhere nearby, and you have to recognize it, stand up, and put in the time and work it takes to get to it. This isn't because the universe is cruel. It's because the universe is smart. It has its own cat-string theory and knows we don't appreciate things that fall into our laps.

As a loyal believer in the Auteur Theory I first felt editing was but the logical consequence of the way in which one shoots. But, what I learned is that it is actually another writing.

I don't believe that the ultimate theory will come by steady work along existing lines. We need something new. We can't predict what that will be or when we will find it because if we knew that, we would have found it already!

Those who are not shocked when they first come across quantum theory cannot possibly have understood it.

If any human being earnestly desire to push on to new discoveries instead of just retaining and using the old; to win victories over Nature as a worker rather than over hostile critics as a disputant; to attain, in fact, clear and demonstrative knowlegde instead of attractive and probable theory; we invite him as a true son of Science to join our ranks.

How could so many intelligent people be so grievously wrong for such an extended period of time? How could they ignore so much overwhelming evidence that contradicted their most basic theories? These questions, too, deserve their own discipline: the sociology of error.

Still, it is an error to argue in front of your data. You find yourself insensibly twisting them round to fit your theories.

The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.
