“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.”

“I find the whole business of religion profoundly interesting. But it does mystify me that otherwise intelligent people take it seriously.”

“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!”

“So, the world is fine. We don’t have to save the world—the world is big enough to look after itself. What we have to be concerned about, is whether or not the world we live in, will be capable of sustaining us in it. That’s what we need to think about.”

“We have normality. I repeat, we have normality. Anything you still can’t cope with is therefore your own problem.”

“What’s up?” [asked Ford.]”I don’t know,” said Marvin, “I’ve never been there.”

“I think fish is nice, but then I think that rain is wet, so who am I to judge?”

“I don’t accept the currently fashionable assertion that any view is automatically as worthy of respect as any equal and opposite view. My view is that the moon is made of rock. If someone says to me ‘Well, you haven’t been there, have you? You haven’t seen it for yourself, so my view that it is made of Norwegian Beaver Cheese is equally valid’ – then I can’t even be bothered to argue. There is such a thing as the burden of proof, and in the case of god, as in the case of the composition of the moon, this has shifted radically. God used to be the best explanation we’d got, and we’ve now got vastly better ones. God is no longer an explanation of anything, but has instead become something that would itself need an insurmountable amount of explaining. So I don’t think that being convinced that there is no god is as irrational or arrogant a point of view as belief that there is. I don’t think the matter calls for even-handedness at all.”

“He attacked everything in life with a mix of extraordinary genius and naive incompetence, and it was often difficult to tell which was which.”

“If you try and take a cat apart to see how it works, the first thing you have on your hands is a non-working cat.”

“Can’t stand all these poisonous creatures, all these snakes and insects and fish and things. Wretched things, biting everybody. And then people expect me to tell them what to do about it. I’ll tell them what to do. Don’t get bitten in the first place. (quoting Dr. Struan Sutherland)”

“I refuse to answer that question on the grounds that I don’t know the answer”
