It doesn’t matter what you believe, it matters what is true. People need to think about truth rather than just belief. I might believe that the earth is flat, but it isn’t. I might believe the sky is green, but it isn’t. I might believe you will send me a thousand dollars, but you probably won’t! We must help people distinguish between their beliefs and what is true.
— Mark Cahill, from One Thing You Can’t Do In Heaven, p. 150
