“Make this the golden rule, the equivalent of the Hippocratic oath: Everything we ask a child to do should be worth doing.”

“For a human being, nothing comes naturally,' said Grumman. 'We have to learn everything we do.”

“If I'm reading something I happen to know and gets it wrong, I just don't trust the book any more. What I ask of a novel I'm reading is that it should know a fraction more about the things I know than I do. When I'm writing...I ask myself: would I be convinced by this if I read it? If I knocked against this bit of scenery, would it feel solid?”

“What work do I have to do then?" said Will, but went on at once, "No, on second thought, don't tell me. I shall decide what I do. If you say my work is fighting, or healing, or exploring, or whatever you might say, I'll always be thinking about it. And if I do end up doing that, I'll be resentful because it'll feel as if I didn't have a choice, and if I don't do it, I'll feel guilty because I should. Whatever I do, I will choose it, no one else.”

“From what we are, spirit; from what we do, matter. Matter and spirit are one.”

“I'm trying to undermine the basis of Christian belief... I'm not in the business of offending people. I find the books upholding certain values that I think are important, such as life is immensely valuable and this world is an extraordinarily beautiful place. We should do what we can to increase the amount of wisdom in the world.[Washington Post interview, 19 February 2001]”

“I think there's a difference between (a) offending people for its own sake, which I don't necessarily want to do, because some people are good and decent and it would be unkind to upset them simply to indulge my own self-importance, and (b) challenging their prejudices, their preconceptions, or their comfortable assumptions. I'm very happy to do that. But we need to be on our guard when people say they're offended. No one actually has the right to go through life without being offended. Some people think they can say "such-and-such offends me" and that will stop the "offensive" words or behaviour and force the "offender" to apologise. I'm very much against that tactic. No one should be able to shut down discussion by making their feelings more important than the search for truth. If such people are offended, they should put up with it.”
