“How do we distinguish between the legitimate skepticism of those who scoffed at cold fusion, and the stifling dogma of the seventeenthcentury clergymen who, doubting Galileo's claim that the earth was not the center of the solar system, put him under house arrest for the last eight years of his life? In part, the answer lies in the distinction between skepticism and closed-mindedness. Many scientists who were skeptical about cold fusion nevertheless tried to replicate the reported phenomenon in their own labs; Galileo's critics refused to look at the pertinent data.”

“Johnson is a radical skeptic, insisting, in the best Socratic tradition, that everything be put on the table for examination. By contrast, most skeptics opposed to him are selective skeptics, applying their skepticism to the things they dislike (notably religion) and refusing to apply their skepticism to the things they do like (notably Darwinism). On two occasions I’ve urged Michael Shermer, publisher of Skeptic Magazine, to put me on its editorial board as the resident skeptic of Darwinism. Though Shermer and I know each other and are quite friendly, he never got back to me about joining his editorial board.”

“The skeptic does not mean him who doubts, but him who investigates or researches, as opposed to him who asserts and thinks that he has found.”

“I'm beginning to be skeptical of my own skepticism.”

“I wanted to cast doubt on the step he was about to take, to help him see there are other ways to live, other ways to seek knowledge, love...even self-transformation. I wanted to convince him his dignity depended on maintaining a free, skeptical attitude towards doctrine. I wanted...to save him...Doubt, like faith, has to be learned. It is a skill. But the curious thing about skepticism is that its adherents, ancient and modern, have so often been proselytizers. In reading them, I've often wanted to ask: "Why do you care?" Their skepticism offers no good answer to that question.”

“He put his arms about himself as if he were cold. "I do not know who to be without him.”
