“Everyone has to believe something. You don’t get to opt out. . . . That we will believe is not in question. The question is what we will believe in, and why.” Of course, he continues, our belief structure may suffer from new evidence, or new challenges. “In that case we do need to adjust our beliefs to accommodate less evidence than we had before. Even in that case, however, we ought not to fool ourselves into thinking that we can simply stop believing. We can only believe in different things.”
