“Now, the invention of the scientific method and science is, I'm sure we'll all agree, the most powerful intellectual idea, the most powerful framework for thinking and investigating and understanding and challenging the world around us that there is, and that it rests on the premise that any idea is there to be attacked and if it withstands the attack then it lives to fight another day and if it doesn't withstand the attack then down it goes. Religion doesn't seem to work like that; it has certain ideas at the heart of it which we call sacred or holy or whatever. That's an idea we're so familiar with, whether we subscribe to it or not, that it's kind of odd to think what it actually means, because really what it means is 'Here is an idea or a notion that you're not allowed to say anything bad about; you're just not. Why not? - because you're not!”

“Religion... has certain ideas at the heart of it which we call sacred or holy or whatever... If someone votes for a party that you don't agree with, you're free to argue about it as much as you like; everybody will have an argument but nobody feels aggrieved by it. If somebody thinks taxes should go up or down you are free to have an argument about it. But on the other hand if somebody says 'I must [not] move a light switch on a Saturday', you say, 'I respect that'... Yet when you look at it rationally there is no reason why those ideas shouldn't be as open to debate as any other, except that we have agreed somehow between us that they shouldn't be.”

“Q: Do you feel concerned that after all this work, people won't treat [Starship Titanic] with the gravity of, say, a movie or a book? That they won't treat it as an art form?D.A.: I hope that's the case, yes. I get very worried about this idea of art. Having been an English literary graduate, I've been trying to avoid the idea of doing art ever since. I think the idea of art kills creativity. ... [I]f somebody wants to come along and say, "Oh, it's art," that's as may be. I don't really mind that much. But I think that's for other people to decide after the fact. It isn't what you should be aiming to do. There's nothing worse than sitting down to write a novel and saying, "Well, okay, I'm going to do something of high artistic worth." ... I think you get most of the most interesting work done in fields where people don't think they're doing art, but merely practicing a craft, and working as good craftsmen. ... I tend to get very suspicious of anything that thinks it's art while it's being created.”

“I've heard an idea proposed, I've no idea how seriously, to account for the sensation of vertigo. It's an idea that I instinctively like and it goes like this. The dizzy sensation we experience when standing in high places is not simply a fear of falling. It's often the case that the only thing likely to make us fall is the actual dizziness itself, so it is, at best, an extremely irrational, even self-fulfilling fear. However, in the distant past of our evolutionary journey toward our current state, we lived in trees. We leapt from tree to tree. There are even those who speculate that we may have something birdlike in our ancestral line. In which case, there may be some part of our mind that, when confronted with a void, expects to be able to leap out into it and even urges us to do so. So what you end up with is a conflict between a primitive, atavistic part of your mind which is saying "Jump!" and the more modern, rational part of your mind which is saying, "For Christ's sake, don't!" In fact, vertigo is explained by some not as the fear of falling, but as the temptation to jump!”

“The idea was fantastically, wildly improbable. But like most fantastically, wildly improbable ideas it was at least as worthy of consideration as a more mundane one to which the facts had been strenuously bent to fit.”

“This is rather as if you imagine a puddle waking up one morning and thinking, 'This is an interesting world I find myself in — an interesting hole I find myself in — fits me rather neatly, doesn't it? In fact it fits me staggeringly well, must have been made to have me in it!' This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, frantically hanging on to the notion that everything's going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for.”

“The world is a thing of utter inordinate complexity and richness and strangeness that is absolutely awesome. I mean the idea that such complexity can arise not only out of such simplicity, but probably absolutely out of nothing, is the most fabulous extraordinary idea. And once you get some kind of inkling of how that might have happened, it’s just wonderful. And … the opportunity to spend 70 or 80 years of your life in such a universe is time well spent as far as I am concerned.”
