Theory Quotes

“As to harmonizing the theory of evolution with the Biblical account of creation, I do not believe it can be done, and I do not see why it should be. The story of Genesis is beautiful, and profoundly significant as symbolism: there is no good reason to torture it into conformity with modern theory.”

“The purpose of scientific method is to select a single truth from among many hypothetical truths. That, more than anything else, is what science is all about. But historically science has done exactly the opposite. Through multiplication upon multiplication of facts, information, theories and hypotheses, it is science itself that is leading mankind from single absolute truths to multiple indeterminate, relative ones.”

“We continually forget that the sphere of morals is the sphere of action, that speculation in regard to morality is but observation and must remain in the sphere of intellectual comment, that a situation does not really become moral until we are confronted with the question of what shall be done in a concrete case, and are obliged to act upon our theory.”

“'Participant' is the incontrovertible new concept given by quantum mechanics. It strikes down the 'observer' of classical theory, the man who stands safely behind the thick glass wall and watches what goes on without taking part. It can't be done, quantum mechanics says it...May the universe in some sense be 'brought into being' by the participation of those who participate?”

“We come finally, however, to the relation of the ideal theory to real world, or "real" probability. If he is consistent a man of the mathematical school washes his hands of applications. To someone who wants them he would say that the ideal system runs parallel to the usual theory: "If this is what you want, try it: it is not my business to justify application of the system; that can only be done by philosophizing; I am a mathematician". In practice he is apt to say: "try this; if it works that will justify it".”

“A theory of personal resurrection or reincarnation of the individual is untenable when we but pause to consider the magnitude of the idea. On the contrary, I must believe that rather than the survival of all, we must look for survival only in the spirit of the good we have done in passing through.Once obsolete, an automobile is thrown to the scrap heap. Once here and gone, the human life has likewise served its purpose. If it has been a good life, it has been sufficient. There is no need for another.”

“Those who are in love with practice without knowledge are like the sailor who gets into a ship without rudder or compass and who never can be certain whether he is going. Practice must always be founded on sound theory, and to this Perspective is the guide and the gateway; and without this nothing can be done well in the matter of drawing.”

“Because the true perfection of a practical occupation consists not only in knowing the actual performance of the occupation but also in its explanation, why the work is done a in a particular way, and because the art of calculating is a practical occupation, it is clear that it is pertinent to concern oneself with the theory.”

“The real trouble about women is that they must always go on trying to adapt themselves to men's theories of women, as they alwayshave done. When a woman is thoroughly herself, she is being what her type of man wants her to be. When a woman is hysterical it's because she doesn't quite know what to be, which pattern to follow, which man's picture of woman to live up to.”

“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. People love to read stories. They like to know you as a real person who has your struggle, pain, success and failure, etc. One well-known example is Jared Fogle's weight loss story which made millions of dollars for Subway. Start to collect your stories from today and use them in your ad campaigns.”

“Don't get seduced by your own stuff. Don't get high on your own supply. The hardest thing as a filmmaker is when you're watching a film that you've worked on for several years. You know every frame so intimately that holding lots of the objectivity of a new viewer who has just seen it for the first time is the hardest thing. Every aesthetic decision you make - and you make thousands of them every day, have to - in theory, must be done from you being a blank slate. You almost have to run a program, like a mind wipe, every time you watch the movie.”

“We went to the moon using just Newton's laws of motion and gravity. Newtonian dynamics we call it. So then we find out, "Well, this works because there's certain regimes we've never tested it in." Had we done so, we would show that it didn't work: For example, at very high speeds, very high gravity, Newton's laws fail. They just fail. You need Einstein's laws of motion and gravity. Those would be his special theory of relativity and general theory of relativity. Now you invoke those and it works.”
