In these researches I followed the principles of the experimental method that we have established, i.e., that, in presence of a well-noted, new fact which contradicts a theory, instead of keeping the theory and abandoning the fact, I should keep and study the fact, and I hastened to give up the theory.

Claude Bernard

I don't think about a theory of everything when I do my research. And even if we knew the ultimate underlying theory, how are you going to explain the fact that we're sitting here? Solving string theory won't tell us how humanity was born.

Lisa Randall

When we meet a fact which contradicts a prevailing theory, we must accept the fact and abandon the theory, even when the theory is supported by great names and generally accepted.

Claude Bernard

The fact -- not theory -- that evolution has occurred and the Darwinian theory as to how it occurred have become so confused in popular opinion that the distinction must be stressed.

George Gaylord Simpson

The fact - not theory - that evolution has occurred and the Darwinian theory as to how it occurred have become so confused in popular opinion that the distinction must be stressed.

George Gaylord Simpson

Evolution is far more than a belief or an educated guess about how people came to be as they are. It is, in fact, the product of converging evidence from many, many different fields of science. Many, many thousands of studies that, in fact, have provided a theory, an organizing principal in fact, that describes how humans came to be.

Alan I. Leshner

The theory of high-intensity, anaerobic, bodybuilding exercise is not true because I or anyone else, no matter how many might agree, say it is true. It is the fact that the logic of the theory is unassailable which makes it true.

Mike Mentzer

If white American feminist theory need not deal with the differences between us, and the resulting difference in our oppressions, then how do you deal with the fact that the women who clean your houses and tend your children while you attend conferences on feminist theory are, for the most part, poor women and women of Color? What is the theory behind racist feminism?

Audre Lorde

Everything must be taken into account. If the fact will not fit the theory---let the theory go.

Agatha Christie

Evolution is a fact. It is the best explanation of what is known from observations. It's a theory as powerful as the theory of gravity.

Donald Johanson

The theory of evolution, like the theory of gravity, is a scientific fact.

Neil deGrasse Tyson

The empty tomb stands, a veritable rock, as an essential element in the evidence for the resurrection. To suggest that it was not in fact empty at all, as some have done, seems to me ridiculous.

Norman Anderson

When the fact doesn't meet the theory then let go the theory.

Agatha Christie

There is not enough evidence, consistent evidence to make it as fact, and I say that because for theory to become a fact, it needs to consistently have the same results after it goes through a series of tests. The tests that they put- that they use to support evolution do not have consistent results. Now too many people are blindly accepting evolution as fact. But when you get down to the hard evidence, it's merely a theory.

Christine O'Donnell

Some claim evolution is just a theory. As if it were merely an opinion. The theory of evolution, like the theory of gravity, is a scientific fact. Evolution really happened. Accepting our kinship with all life on Earth is not only solid science. In my view, it’s also a soaring spiritual experience.

Neil deGrasse Tyson

No matter how beautiful the theory, one irritating fact can dismiss the entire formulism, so it has to be proven.
