“The strength of a theory is not what it allows, but what it prohibits; if you can invent an equally persuasive explanation for any outcome, you have zero knowledge.”

“Your strength as a rationalist is your ability to be more confused by fiction than by reality. If you are equally good at explaining any outcome, you have zero knowledge.”

Eliezer Yudkowsky (1979) American blogger, writer, and artificial intelligence researcher

Your Strength As A Rationalist http://lesswrong.com/lw/if/your_strength_as_a_rationalist/ (August 2007)

“A theory, is a body of knowledge, that is supportive of, and explanative of facts. Scientific laws are included within a theory, facts are included within a theory, that's why you have the theory of evolution, the theory of gravity, the theory of relativity. There is no concept in creationism, which meets any of the qualifications of a scientific theory, none. You have no facts, you have no laws, you have no evidence, you have no explanative power. All you have, is whatever science can't explain, you pretend you can.”

“If you have a theory, you must try to explain what’s good and what’s bad about it equally. In science, you learn a kind of standard integrity and honesty.”

Richard Feynman book What Do You Care What Other People Think?

"Afterthoughts," p. 217-218
What Do You Care What Other People Think? (1988)
Context: The only way to have real success in science, the field I’m familiar with, is to describe the evidence very carefully without regard to the way you feel it should be. If you have a theory, you must try to explain what’s good and what’s bad about it equally. In science, you learn a kind of standard integrity and honesty.

“No one invented it on purpose, it was invented in a lucky accident. …By rights, string theory shouldn't have been invented until our knowledge of some of the areas that are prerequisite… had developed to the point that it was possible for us to have the right concept of what it is all about.”

Edward Witten (1951) American theoretical physicist

"Edward Witten" interview, Superstrings: A Theory of Everything? (1992) ed. P.C.W. Davies, Julian Brown
Context: It's been said that string theory is part of the physics of the twenty-first century that fell by chance into the twentieth century. That's a remark that was made by a leading physicist about fifteen years ago.... String theory was invented essentially by accident in a long series of events, starting with the Veneziano model... No one invented it on purpose, it was invented in a lucky accident.... By rights, string theory shouldn't have been invented until our knowledge of some of the areas that are prerequisite... had developed to the point that it was possible for us to have the right concept of what it is all about.

“The holding of a myth explanation of any problem whereon mankind has attained true knowledge is what I term enslaved thought or dogmatism.”

Karl Pearson (1857–1936) English mathematician and biometrician

The Ethic of Freethought (Mar 6, 1883)

“More and more, people see that solving any problem is a question of acquiring knowledge and having respect for the cognitive and epistemological processes involved in the human brain: use what you know, learn what you can, and if you have to guess, be aware that you do so you can go back and update your guesses when you (hopefully) learn more.”
