“Sorry, did I say something wrong?" said Marvin, dragging himself on regardless. "Pardon me for breathing, which I never do anyway so I don't know why I bother to say it, oh God I'm so depressed. Here's another one of those self-satisfied doors. Life! Don't talk to me about life.”

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

“I don't know what this great thing I'm meant to be doing is, and it looks to me as if I was supposed not to know. And I resent that, right? "The old me knew. The old me cared. Fine, so far so good. Except that the old me cared so much that he actually got inside his own brain--my own brain--and locked off the bits that knew and cared, because if I knew and cared I wouldn't be able to do it. [...] "But this former self of mine killed himself off, didn't he, by changing my brain? Okay, that was his choice. This new me has its own choices to make, and by a strange coincidence those choices involve not knowing and not caring about this big number, whatever it is. That's what he wanted, that's what he got. "Except this old self of mine tired to leave himself in control, leaving orders for me in the bit of my brain he locked off. Well, I don't want to know, and I don't want to hear them. That's my choice. I'm not going to be anybody's puppet, particularly not my own. [...] "The old me is dead! [...] Killed himself! The dead shouldn't hang about trying t0 interfere with the living.”

“Simple. I got very bored and depressed, so I went and plugged myself in to its external computer feed. I talked to the computer at great length and explained my view of the Universe to it," said Marvin."And what happened?" pressed Ford."It committed suicide," said Marvin and stalked off back to the Heart of Gold.”

“You know," said Arthur, "it's at times like this, when I'm trapped in a Vogon airlock with a man from Betelgeuse, and about to die of asphyxiation in deep space that I really wish I'd listened to what my mother told me when I was young.""Why, what did she tell you?""I don't know, I didn't listen.”

“It comes from a very ancient democracy, you see...""You mean, it comes from a world of lizards?""No," said Ford, who by this time was a little more rational and coherent than he had been, having finally had the coffee forced down him, "nothing so simple. Nothing anything like so straightforward. On its world, the people are people. The leaders are lizards. The people hate the lizards and the lizards rule the people.""Odd," said Arthur, "I thought you said it was a democracy.""I did," said Ford. "It is.""So," said Arthur, hoping he wasn't sounding ridiculously obtuse, "why don't people get rid of the lizards?""It honestly doesn't occur to them," said Ford. "They've all got the vote, so they all pretty much assume that the government they've voted in more or less approximates to the government they want.""You mean they actually vote for the lizards?""Oh yes," said Ford with a shrug, "of course.""But," said Arthur, going for the big one again, "why?""Because if they didn't vote for a lizard," said Ford, "the wrong lizard might get in. Got any gin?""What?""I said," said Ford, with an increasing air of urgency creeping into his voice, "have you got any gin?""I'll look. Tell me about the lizards."Ford shrugged again."Some people say that the lizards are the best thing that ever happenned to them," he said. "They're completely wrong of course, completely and utterly wrong, but someone's got to say it.""But that's terrible," said Arthur."Listen, bud," said Ford, "if I had one Altairian dollar for every time I heard one bit of the Universe look at another bit of the Universe and say 'That's terrible' I wouldn't be sitting here like a lemon looking for a gin.”

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