“This is how deep truths are winnowed from deep nonsense.”
Source: The Demon-Haunted World : Science as a Candle in the Dark (1995), Ch. 17 : The Marriage of Skepticism and Wonder
Context: At the heart of science is an essential balance between two seemingly contradictory attitudes - an openness to new ideas, no matter how bizarre or counterintuitive, and the most ruthlessly skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. The collective enterprise of creative thinking and skeptical thinking, working together, keeps the field on track. Those two seemingly contradictory attitudes are, though, in some tension.
