“In astrology the rules happen to be about stars and planets, but they could be about ducks and drakes for all the difference it would make. It's just a way of thinking about a problem which lets the shape of that problem begin to emerge. The more rules, the tinier the rules, the more arbitrary they are, the better. It's like throwing a handful of fine graphite dust on a piece of paper to see where the hidden indentations are. It lets you see the words that were written on the piece of paper above it that's now been taken away and hidden. The graphite's not important. It's just the means of revealing the indentations. So you see, astrology's nothing to do with astronomy. It's just to do with people thinking about people.”

“This planet has - or rather had - a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy.”

“Shh!" said Ford. "It's conical. So what you do is, you see, you fill it with fine white sand, alright? Or sugar. Fine white sand, and/or sugar. Anything. Doesn't matter. Sugar's fine. And when it's full, you pull the plug out... are you listening?" "I'm listening." "You pull the plug out, and it all just twirls away, twirls away you see, out of the plughole. "Clever." "That's not the clever bit. This is the clever bit, I remember now that this is the clever bit. The clever bit is that you then thread the film in the projector... backwards!" "Backwards?" "Yes. Threading it backwards is definitely the clever bit. So then, you just sit and watch it, and everything just appears to spiral upwards out of the plughole and fill the bath. See?" "And that's how the Universe began is it?" said Arthur. "No," said Ford, "but it's a marvelous way to relax.”

“What have you done to it, Monkeyman? - he breathed. - Well, - said Arthur, - nothing in fact. It's just that I think ashort while ago it was trying to work out how to... - Yes? - Make me some tea. - That's right guys, - the computer sang out suddenly, - just copingwith that problem right now, and wow, it's a biggy. Be with you in awhile." It lapsed back into a silence that was only matched for sheerintensity by the silence of the three people staring at Arthur Dent.”

“If the Universe came to an end every time there was some uncertainty about what had happened in it, it would never have got beyond the first picosecond. And many of course don't. It's like a human body, you see. A few cuts and bruises here and there don't hurt it. Not even major surgery if it's done properly. Paradoxes are just the scar tissue. Time and space heal themselves up around them and people simply remember a version of events which makes as much sense as they require it to make.”

“The major problem—one of the major problems, for there are several—one of the many major problems with governing people is that of whom you get to do it; or rather of who manages to get people to let them do it to them. To summarize: it is a well-known fact that those people who must want to rule people are, ipso facto, those least suited to do it. To summarize the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job.”

“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.”
