Charles Darwin Quotes

It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.

To the scientist, failure to flip-flop in the face of contradictory evidence is irrational and dangerous behavior. And scientists will often flip-flop at almost light speed. Often it takes only a single observation to flip-flop thousands of scientifically learned people.

We don't regard any scientific theory as the absolute truth.

It is crucial for scientists to be willing to be wrong; otherwise, you might not do the most important experiments, or you may ignore your most important findings.

Science is imagination in the service of the verifiable truth, and that service is indeed communal. It cannot be rigidly planned. Rather, it requires freedom and courage and the plural contributions of many different kinds of people who must maintain their individuality while giving to the group.

True science teaches, above all, to doubt and to be ignorant.

Scientists are skeptics. It's unfortunate that the word 'skeptic' has taken on other connotations in the culture involving nihilism and cynicism. Really, in its pure and original meaning, it's just thoughtful inquiry.

I was not surprised by the results of the Horizon experiments, but I remain willing to observe and consider any and all other tests that are done under similarly precise conditions.

For science must breathe the oxygen of freedom.

If you're an adult and you choose not to believe in science, fine, but please don't prevent your children from learning about it and letting them draw their own conclusions.

Disagreements are one of the fundamental positive aspects of science.

True science teaches, above all, to doubt

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion

But whereas skepticism and uncertainty have always been the heart and soul of science, confidence and certainty are the coin of the realm in much of today’s public discourse. Unquestioning confidence is deeply troubling for the scientific community because it is not the currency we trade in, and it has led people in America and around the world to question scientific enterprise itself. We should all be troubled when science is treated as if it were an ideology rather than a discipline.

When we seek a textbook case for the proper operation of science, the correction of certain error offers far more promise than the establishment of probable truth. Confirmed hunches, of course, are more upbeat than discredited hypotheses. Since the worst traditions of "popular" writing falsely equate instruction with sweetness and light, our promotional literature abounds with insipid tales in the heroic mode, although tough stories of disappointment and loss give deeper insight into a methodology that the celebrated philosopher Karl Popper once labeled as "conjecture and refutation.

It's high time to rescue "intelligent design" from the politics of religion. There are too many riddles not yet answered by either biology or the Bible, and by asking them honestly, without foregone conclusions, science could take a huge leap forward.

Scientists are skeptics. It's unfortunate that the word 'skeptic' has taken on other connotations in the culture involving nihilism and cynicism. Really, in its pure and original meaning, it's just thoughtful inquiry.

I am convinced that everything that is worth while in the world has been accomplished by the free, inquiring, critical spirit, and that the preservation of this spirit is more important than any social system whatsoever. But the men of ritual and the men of barbarism are capable of shutting up the men of science and silencing them forever.

Too much openness and you accept every notion, idea, and hypothesis-which is tantamount to knowing nothing. Too much skepticism-especially rejection of new ideas before they are adequately tested-and you're not only unpleasantly grumpy, but also closed to the advance of science. A judicious mix is what we need.

To the scientists of the Renaissance, your critic was really your ally, helping you advance upon reality. Critics in science are not like drama critics, determining flops and successes. Criticism to scientists is just another means of finding out whether they're wrong, like running another experiment to see if it confirms or refutes a theory. Along with the advocacy principle of the courtroom, It is one of the best ways human beings have evolved to get closer to the truth.

"True science has no belief," says Dr. Fenwick, in Bulwer-Lytton's 'Strange Story;' "true science knows but three states of mind: denial, conviction, and the vast interval between the two, which is not belief, but the suspension of judgment." Such, perhaps, was true science in Dr. Fenwick's days. But the true science of our modern times proceeds otherwise; it either denies point-blank, without any preliminary investigation, or sits in the interim, between denial and conviction, and, dictionary in hand, invents new Graeco-Latin appellations for non-existing kinds of hysteria!

Science alone of all the subjects contains within itself the lesson of the danger of belief in the infallibility of the greatest teachers of the preceding generation.

No scientist ever believes that he has the final answer or the ultimate truth on anything.

I believe that ideas such as absolute certitude, absolute exactness, final truth, etc. are figments of the imagination which should not be admissible in any field of science... This loosening of thinking seems to me to be the greatest blessing which modern science has given to us. For the belief in a single truth and in being the possessor thereof is the root cause of all evil in the world.
