“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.”

“There is no "tropical island paradise" I know of which remotely matches up to the fantasy ideal that such a phrase is meant to conjure up, or even to what we find described in holiday brochures. It's natural to put this down to the discrepancy we are all used to finding between what advertisers promise and what the real world delivers. It doesn't surprise us much any more. So it can come as a shock to realise that the world we hear described by travellers of previous centuries (or even previous decades) and biologists of today really did exist. The state it's in now is only the result of what we've done to it, and the mildness of the disappointment we feel when we arrive somewhere and find that it's a bit tatty is only a measure of how far our own expectations have been degraded and how little we understand what we've lost. The people who do understand what we've lost are the ones who are rushing around in a frenzy trying to save the bits that are left.”

“David Attenborough has said that Bali is the most beautiful place in the world, but he must have been there longer than we were, and seen different bits, because most of what we saw in the couple of days we were there sorting out our travel arrangements was awful. It was just the tourist area, i.e., that part of Bali which has been made almost exactly the same as everywhere else in the world for the sake of people who have come all this way to see Bali.”

“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!”

“I have detected disturbances in the wash.''The wash?''The space-time wash.''Are we talking about some sort of Vogon laundromat, or what are we talking about?''Eddies in the space-time continuum.''Ah...is he. Is he.''What?''Er, who is Eddy, then, exactly?”

“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.”

“First we thought the PC was a calculator. Then we found out how to turn numbers into letters with ASCII — and we thought it was a typewriter. Then we discovered graphics, and we thought it was a television. With the World Wide Web, we've realized it's a brochure.”
