A mathematician is a person who can find analogies between theorems; a better mathematician is one who can see analogies between proofs and the best mathematician can notice analogies between theories.
Stefan Banach

A people represents not so much an aggregate of ideas and theories as of obsessions.
Emile M. Cioran

A work of art that contains theories is like an object on which the price tag has been left.
Alexander Pope

Academics love to make theories about a body of work, but each book consumes the writer and is the sum of his or her world.
Jeanette Winterson

And now, without having wearied my friends, I hope, with detailed scientific accounts, theories, or deductions, I will only say that I have endeavoured to tell just the story of the adventure itself.
Joshua Slocum

And the continuity of our science has not been affected by all these turbulent happenings, as the older theories have always been included as limiting cases in the new ones.
Max Born

As a rule we disbelieve all the facts and theories for which we have no use.
Gustave Flaubert

Because essentially Schoenberg was an extremely gifted man. And in spite of many of his theories and so on, when he really began to write music, he still was guided very much by his internal hearing, by what we call your internal ear.
Leo Ornstein

Before I got married I had six theories about bringing up children; now I have six children, and no theories.
John Wilmot

Before I married, I had three theories about raising children and no children. Now, I have three children and no theories.
John Wilmot

During the many centuries that magic, here on this planet, was presumed to have worked, there were at least as many theories as to how magic worked as there were cultures and religions.
Lynn Abbey

Every theory presented as a scientific concept is just that; it's a theory that tries to explain more about the world than previous theories have done. It is open to being challenged and to being proven incorrect.
Marvin Harris

Evolutionary cosmology formulates theories in which a universe is capable of giving rise to and generating future universes out of itself, within black holes or whatever.
Robert Nozick

Facts do not speak for themselves. They speak for or against competing theories. Facts divorced from theories or visions are mere isolated curiosities.
Thomas Sowell

From whichever angle one looks at it, the application of racial theories remains a striking proof of the lowered demands of public opinion upon the purity of critical judgment.
Johan Huizinga

Genetic theories, I gather, have been cherished academically with detachment.
Allen Tate

Good tests kill flawed theories; we remain alive to guess again.
Karl Popper

How thoroughly it is ingrained in mathematical science that every real advance goes hand in hand with the invention of sharper tools and simpler methods which, at the same time, assist in understanding earlier theories and in casting aside some more complicated developments.
David Hilbert

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

I am more fond of achieving than striving. My theories must prove to be facts or be discarded as worthless. My efforts must soon be crowned with success, or discontinued.
Carolyn Wells
