Theory Quotes
-
Science, at least as it has been practiced for the last century or two, begins by assembling facts—the data—and then seeks an overarching theory to unify and explain those facts. Whether it’s the big bang theory or plate tectonics or germ theory, from the cosmic to the microscopic, the approach is the same. Ignoring or denying inconvenient facts is not permitted. Trying to uncover facts that disprove a treasured theory is encouraged. This is part of the modern scientific method, which holds that theories should be subjected to rigorous attempts to prove them false before they become widely accepted (or discarded as incorrect). In the law, however, the process works in exactly the opposite direction.
-
In theory, it makes a lot of sense to combine the two operations, especially on the back end. But merging the two actual portal consumer experiences into a unified site will be a nightmare.
-
It's kind of hard to sell 'trickle down,' so the supply-side formula was the only way to get a tax policy that was really 'trickle down.' Supply-side is 'trickle-down' theory.
-
The true lady is in theory either a virgin or a lawful wife.
-
This is my theory: the people who shouldn't hate themselves, do hate themselves. And the people who should hate themselves, don't hate themselves. The world is all backwards. See, this is one of the many reasons why God and I are not good friends.
-
You hear the word, and believe it in theory, while you deny it in practice. I say to you, that 'you deceive yourselves'.
-
It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory.
-
Nothing is known in our profession by guess; and I do not believe, that from the first dawn of medical science to the present moment, a single correct idea has ever emanated from conjecture: it is right therefore, that those who are studying their profession should be aware that there is no short road to knowledge; and that observation on the diseased living, examination of the dead, and experiments upon living animals, are the only sources of true knowledge; and that inductions from these are the sole bases of legitimate theory.
-
The theory that music has a depraving effect on morals has now been abandoned to the old women of both sexes.
-
My theory is that all of Scottish cuisine is based on a dare.
-
The true test of a brilliant theory is what first is thought to be wrong is later shown to be obvious.
-
Ahimsa in theory no one knows. It is as indefinable as God.
-
One theory says that if you treat people well, you're more likely to encourage them to do what you want, making all the effort pay off. Do this, get that. Another one, which I prefer, is that you might consider treating people with kindness merely because you can. Regardless of what they choose to do in response, this is what you choose to do. Because you can.
-
From a certain temperature on, the molecules 'condense' without attractive forces; that is, they accumulate at zero velocity. The theory is pretty, but is there some truth in it.
-
The mathematicians have been very much absorbed with finding the general solution of algebraic equations, and several of them have tried to prove the impossibility of it. However, if I am not mistaken, they have not as yet succeeded. I therefore dare hope that the mathematicians will receive this memoir with good will, for its purpose is to fill this gap in the theory of algebraic equations.
-
Partial knowledge is more triumphant than complete knowledge; it takes things to be simpler than they are, and so makes its theory more popular and convincing.
-
Criticism - however valid or intellectually engaging - tends to get in the way of a writer who has anything personal to say. A tightrope walker may require practice, but if he starts a theory of equilibrium he will lose grace (and probably fall off).
-
The 'science' for which the United States is respected has nothing to do with the unscientific and baseless theory of evolution.
-
There is a mask of theory over the whole face of nature.
-
Theory must mediate between all previous truths and certain new experiences
-
As a rule we disbelieve all the facts and theories for which we have no use.
-
The indispensability argument says (roughly) that if you have ample reason to accept an empirical scientific theory that makes indispensable use of mathematics, and that theory entails that numbers exist, then you have ample reason to accept that numbers exist. The argument affirms the antecedent of this conditional, and concludes that you have ample reason to believe that numbers exist. What is striking about this argument is that it seems to show that the empirical reasons that suffice for accepting a scientific theory also suffice for accepting a metaphysical claim.
-
A new theory is guilty until proven innocent, and the pre-existing theory innocent until proven guilty ... Continental drift was guilty until proven innocent.
-
The history of science knows scores of instances where an investigator was in the possession of all the important facts for a new theory but simply failed to ask the right questions.
