“What to do if you find yourself stuck in a crack in the ground underneath a giant boulder you can't move, with no hope of rescue. Consider how lucky you are that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your current circumstances seems more likely, consider how lucky you are that it won't be troubling you much longer.”

“Mr Cjelli, nice to see you back, sir. Sorry you had a spot of bother, hope that's all behind you now.""Indeed, Bill, it is. You find me thriving. And Mrs Roberts? How is she? Foot still troubling her?""Not since she had it off, thanks for asking, sir. Between you and me, sir, I would've been just as happy to have had her amputated and kept the foot. I had a little spot reserved on the mantelpiece, but there we are, we have to take things as we find them."(...)"...thank you, and my best to what remains of Mrs Roberts.”

“It's the story of my life. You see, the quality of any advice anybody has to offer has to be judged against the quality of life they actually lead. Now, as you look through this document you'll see that I've underlined all the major decisions I ever made to make the stand out. They're all indexed and cross-referenced. See? All I can suggest is that if you take decisions that are exactly opposite to the sort of decisions that I've taken, then maybe you won't finish up at the end of your life" --she paused, and filled her lungs for a good should--"in a smelly old cave like this!”

“There’s no point in acting surprised about it. All the planning charts and demolition orders have been on display at your local planning department in Alpha Centauri for 50 of your Earth years, so you’ve had plenty of time to lodge any formal complaint and it’s far too late to start making a fuss about it now. … What do you mean you’ve never been to Alpha Centauri? Oh, for heaven’s sake, mankind, it’s only four light years away, you know. I’m sorry, but if you can’t be bothered to take an interest in local affairs, that’s your own lookout. Energize the demolition beams.”

“What, are you, crazy?' 'It's a possibility I haven't ruled out yet', said Zaphod quietly. 'I know as much about myself as my mind can work out under its current conditions. And its current conditions are not good.”

“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.”

“Time is the worst place, so to speak, to get lost in, as Arthur Dent could testify, having been lost in both time and space a good deal. At least being lost in space kept you busy.”
