"There was constant talk about hewing things and ravaging things and splitting things asunder. Lots of big talk of things being mighty, and of things being riven, and of things being in thrall to other things, but very little attention given, as I now realise, to the laundry."

"It was his subconscious which told him this — that infuriating part of a person's brain which never responds to interrogation, merely gives little meaningful nudges and then sits humming quietly to itself, saying nothing."

"What was the Sherlock Holmes principle? 'Once you have discounted the impossible, then whatever remains, however improbable, must be the truth.' I reject that entirely. The impossible often has a kind of integrity to it which the merely improbable lacks. How often have you been presented with an apparently rational explanation of something that works in all respects other than one, which is just that it is hopelessly improbable? Your instinct is to say 'Yes, but he or she simply wouldn't do that.'"

"...my methods of navigation have their advantage. I may not have gone where I intended to go, but I think I have ended up where I needed to be."

"My own strategy is to find a car, or the nearest equivalent, which looks as if it knows where it's going and follow it. I rarely end up where I was intending to go, but often I end up somewhere I needed to be."

"She held the car grimly to the road as it negotiated the bends with considerable difficulty and the straight sections with only slightly less. The car had landed her in court on one occasion when one of its front wheels had sailed off on a little expedition of its own and nearly caused an accident. The police witness in court had referred to her beloved Citroën as "the alleged car" and the name had subsequently stuck. She was particularly fond of the alleged car for many reasons. If one of its doors, for instance, fell off she could put it back on herself, which is more than you could say for a BMW."

"It was a battered yellow Citroën 2CV which had had one careful owner but also three suicidally reckless ones."

"The device [electronic I Ching calculator] also functioned as an ordinary calculator, but only to a limited degree. It could handle any calculation which returned an answer of anything up to 4. ...anything above 4 it represented merely as "A Suffusion of Yellow." Dirk was not certain if this was a programming error or an insight beyond his ability to fathom, but he was crazy about it anyway, enough to hand over twenty pounds of ready cash for the thing."

"Thor was the God of Thunder and, frankly, acted like it."

"You are disoriented. Blackness swims toward you like a school of eels who have just seen something that eels like a lot."

"Driving a Porsche in London is like bringing a Ming vase to a football game."

"When you are a student or whatever, and you can't afford a car, or a plane fare, or even a train fare, all you can do is hope that someone will stop and pick you up. At the moment we can't afford to go to other planets. We don't have the ships to take us there. There may be other people out there (I don't have any opinions about Life Out There, I just don't know) but it's nice to think that one could, even here and now, be whisked away just by hitchhiking."

"The idea that Bill Gates has appeared like a knight in shining armour to lead all customers out of a mire of technological chaos neatly ignores the fact that it was he, by peddling second rate technology, led them into it in the first place, and continues to do so today."

"I think a nerd is a person who uses the telephone to talk to other people about telephones. And a computer nerd therefore is somebody who uses a computer in order to use a computer."

"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, may 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, it's still 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. We all know that at some point in the future the Universe will come to an end and at some other point, considerably in advance from that but still not immediately pressing, the sun will explode. We feel there's plenty of time to worry about that, but on the other hand that's a very dangerous thing to say."

"There are some oddities in the perspective with which we see the world. The fact that we live at the bottom of a deep gravity well, on the surface of a gas covered planet going around a nuclear fireball 90 million miles away and think this to be normal is obviously some indication of how skewed our perspective tends to be, but we have done various things over intellectual history to slowly correct some of our misapprehensions."

"A learning experience is one of those things that say, "You know that thing you just did? Don't do that.""

"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."

"If you try and take a cat apart to see how it works, the first thing you have on your hands is a nonworking cat. Life is a level of complexity that almost lies outside our vision; it is so far beyond anything we have any means of understanding that we just think of it as a different class of object, a different class of matter; 'life', something that had a mysterious essence about it, was God given, and that's the only explanation we had. The bombshell comes in 1859 when Darwin publishes On the Origin of Species. It takes a long time before we really get to grips with this and begin to understand it, because not only does it seem incredible and thoroughly demeaning to us, but it's yet another shock to our system to discover that not only are we not the centre of the Universe and we're not made by anything, but we started out as some kind of slime and got to where we are via being a monkey. It just doesn't read well."

"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."
