Theories Quotes
-
Were I disposed to consider the comparative merit of each of them facts or theories in medical practice, I should derive most of the evils of medicine from supposed facts, and ascribe all the remedies which have been uniformly and extensively useful, to such theories as are true. Facts are combined and rendered useful only by means of theories, and the more disposed men are to reason, the more minute and extensive they become in their observations.
Benjamin Rush

I never once made a discovery ... I speak without exaggeration that I have constructed three thousand different theories in connection with the electric light ... Yet in only two cases did my experiments prove the truth of my theory.
Thomas A. Edison
-
One's own free unfettered choice, one's own caprice-however wild it may be, one's own fancy worked up at times to frenzy-is that very "most advantageous advantage" which we have overlooked, which comes under no classification and against which all systems and theories are continually being shattered to atoms... [an]will attain his object-that is, convince himself he is a man and not a piano-key!
Fyodor Dostoevsky

Bill Clinton
-
One's own free and unfettered volition, one's own caprice, however wild, one's own fancy, inflamed sometimes to the point of madness - that is the one best and greatest good, which is never taken into consideration because it cannot fit into any classification and the omission of which sends all systems and theories to the devil.
Fyodor Dostoevsky
-
Perhaps generations of students of human evolution, including myself, have been flailing about in the dark; that our data base is too sparse, too slippery, for it to be able to mold our theories. Rather the theories are more statements about us and ideology than about the past. Paleontology reveals more about how humans view themselves than it does about how humans came about, but that is heresy.
David Pilbeam
-
Extra dimensional theories are sometimes considered science fiction with equations. I think that's a wrong attitude. I think extra dimensions are with us, they are with us to stay, and they entered physics a long time ago. They are not going to go away.
Leonard Susskind
-
I am an enthusiast, but not a crank in the sense that I have some pet theories as to the proper construction of a flying machine. I wish to avail myself of all that is already known and then, if possible, add my mite to help on the future worker who will attain final success.
Wilbur Wright
-
Even in the darkest of times we have the right to expect some illumination, and ... such illumination may well come less from theories and concepts than from the uncertain, flickering, and often weak light that some men and women, in their lives and their works, will kindle under almost all circumstances and shed over the time-span that was given them on earth.
Hannah Arendt
-
There's no such thing as 'facts of life'. Only standing theories that haven't been disproved as of yet.
Simon Travaglia
-
Every discovery opens a new field for investigation of facts, shows us the imperfection of our theories. It has justly been said, that the greater the circle of light, the greater the boundary of darkness by which it is surrounded.
Humphry Davy
-
In music I do not look for logic. I am quite intuitive on the whole and know no theories. I never like a work if I cannot intuitively grasp its inner unity .

Even originally well-defined pencils of cathode rays from the Sun cannot reach the Earth. For Birkeland's theories to be correct, the existance of such cathode rays is clearly presupposed to be necessary...and this assumption is untenable.

One never learns to understand truly anything but what one loves.
Johann Wolfgang von Goethe
-
“What does not yet exist cannot now be known. The future is imagined by each man for himself and this process of the imagination is a vital part of the process of decision. But it does not make the future known. The absolute and eternal difference between the recorded past and the unformed future, despite its overwhelming significance for the very stuff of human existence, has been often overlooked in our economic theories.”
G. L. S. Shackle
