Dutch - Philosopher

Theory is worth but little, unless it can explain its own phenomena, and it must effect this without contradicting itself; therefore, the facts are sometimes assimilated to the theory, rather than the theory to the facts.

Charles Caleb Colton

No theory ever agrees with all the facts in its domain, yet it is not always the theory that is to blame. Facts are constituted by older ideologies, and a clash between facts and theories may be proof of progress. It is also a first step in our attempt to find the principles implicit in familiar observational notions.

Paul Feyerabend

Almost all the other fellows do not look from the facts to the theory but from the theory to the facts; they cannot get out of the network of already accepted concepts; instead, comically, they only wriggle about inside.

Albert Einstein

Mainstream economics scholarship produces theory without facts ("pure theory") and facts without theory ("applied economics").

Michel Chossudovsky

Those who cavalierly reject the Theory of Evolution, as not adequately supported by facts, seem quite to forget that their own theory it supported by no facts at all.

Herbert Spencer

All good intellects have repeated, since Bacon's time, that there can be no real knowledge but that which is based on observed facts. This is incontestable, in our present advanced stage; but, if we look back to the primitive stage of human knowledge, we shall see that it must have been otherwise then. If it is true that every theory must be based upon observed facts; it is equally true that facts can not be observed without the guidance of some theory. Without such guidance, our facts would be desultory and fruitless; we could not retain them: for the most part we could not even perceive them.

Auguste Comte

Theory and fact are equally strong and utterly interdependent; one has no meaning without the other. We need theory to organize and interpret facts, even to know what we can or might observe. And we need facts to validate theories and give them substance.

Stephen Jay Gould

Facts are simple and facts are straight. Facts are lazy and facts are late. Facts all come with points of view. Facts don't do what I want them to. Facts just twist the truth around. Facts are living turned inside out.

David Byrne

A theory should not attempt to explain all the facts, because some of the facts are wrong

Francis Crick

If the facts don't fit your theory, just find some new facts.

Susan Juby

Facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome.

Stephen Jay Gould

Theory is the essence of facts. Without theory scientific knowledge would be only worthy of the madhouse.

Oliver Heaviside

If the facts don't fit the theory, change the facts.

Unknown

The theory must not contradict empirical facts.

Albert Einstein

Facts are of not much use, considered as facts. They bewilder by their number and their apparent incoherency. Let them be digested into theory, however, and brought into mutual harmony, and it is another matter.

Oliver Heaviside

The first rule is that you can't really know anything if you just remember isolated facts and try and bang 'em back. If the facts don't hang together on a latticework of theory, you don't have them in a usable form.
