I believe without exception that theory follows practice. Whenever there is a conflict between theory and practice, theory is wrong. As far as I'm concerned, we make theories for what people have done. David Baker
I call it like the domino theory of reality. If you can go one step at a time and it seems to make sense, you can then take your audience into an area that is relatively outlandish. Ivan Reitman
I can easily conceive, most Holy Father, that as soon as some people learn that in this book which I have written concerning the revolutions of the heavenly bodies, I ascribe certain motions to the Earth, they will cry out at once that I and my theory should be rejected. Nicolaus Copernicus
I cannot help fearing that men may reach a point where they look on every new theory as a danger, every innovation as a toilsome trouble, every social advance as a first step toward revolution, and that they may absolutely refuse to move at all. Alexis de Tocqueville
I chose to deal with the science of cryptography. Cryptography began in mathematics. Codes were developed, even from Caesar's time, based on number theory and mathematical principles. I decided to use those principles and designed a work that is encoded. James Sanborn
I definitely don't subscribe to the theory that more instruments, or more vocal tracks, harmony, or double tracking the voice, is a good thing. People do their early albums very stripped down, then each album becomes bloated. Joanna Newsom
I grow daily to honour facts more and more, and theory less and less. A fact, it seems to me, is a great thing; a sentence printed, if not by God, then at least by the Devil. Thomas Carlyle
I had become interested in economics, an interest that was transformed into a lifetime dedication when I met with the mathematical theory of general economic equilibrium. Gerard Debreu
I have a theory about that, if you have to say something, if you have encourage for one second a prospective acting student - he should not go in to acting. Dabney Coleman
I have a theory about the human mind. A brain is a lot like a computer. It will only take so many facts, and then it will go on overload and blow up. Erma Bombeck
I have a theory because I was being beaten up a lot by people outside of school, it was almost like if I could make myself sick enough they'd take sympathy on me. Daniel Johns
I have a theory that the best ads come from personal experience. Some of the good ones I have done have really come out of the real experience of my life, and somehow this has come over as true and valid and persuasive. David Ogilvy
I have this theory that people in Hollywood don't read. They read 'Vanity Fair' and then consider themselves terribly well read. I think I can basically write about anybody without getting caught. Jackie Collins
I have this theory that the likeability question comes up so much more with female characters created by female authors than it does with male characters and male authors. Curtis Sittenfeld
I hesitate to predict whether this theory is true. But if the general opinion of Mankind is optimistic then we're in for a period of extreme popularity for science fiction. David Eddings
