Great intellects are skeptical.
Skepticism is the chastity of the intellect...
The path of sound credence is through the thick forest of skepticism.
Skepticism: the mark and even the pose of the educated mind.
Do not let yourself be tainted with a barren skepticism.
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.

Skepticism has never founded empires, established principals, or changed the world's heart. The great doers in history have always been people of faith.
In questions of science, the authority of a thousand is not worth the humble reasoning of a single individual.
Dogmatism and skepticism are both, in a sense, absolute philosophies; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or ignorance.
Skepticism, riddling the faith of yesterday, prepared the way for the faith of tomorrow.
She believed in nothing; only her skepticism kept her from being an atheist.
On the road from the City of Skepticism, I had to pass through the Valley of Ambiguity.
I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.
