“The difficulty with this conversation is that it's very different from most of the ones I've had of late. Which, as I explained, have mostly been with trees. ”

“Like all Vogon ships, it looked as if it had been not so much designed, as congealed. The unpleasant yellow lumps and edifices which protruded from it at unsightly angles would have disfigured the looks of most ships, but in this case, that was sadly impossible. Uglier things have been spotted in the skies, but not by reliable witnesses.”

“The idea was fantastically, wildly improbable. But like most fantastically, wildly improbable ideas it was at least as worthy of consideration as a more mundane one to which the facts had been strenuously bent to fit.”

“Many were increasingly of the opinion that they’d all made a big mistake in coming down from the trees in the first place. And some said that even the trees had been a bad move, and that no one should ever have left the oceans.”

“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.”

“I've heard an idea proposed, I've no idea how seriously, to account for the sensation of vertigo. It's an idea that I instinctively like and it goes like this. The dizzy sensation we experience when standing in high places is not simply a fear of falling. It's often the case that the only thing likely to make us fall is the actual dizziness itself, so it is, at best, an extremely irrational, even self-fulfilling fear. However, in the distant past of our evolutionary journey toward our current state, we lived in trees. We leapt from tree to tree. There are even those who speculate that we may have something birdlike in our ancestral line. In which case, there may be some part of our mind that, when confronted with a void, expects to be able to leap out into it and even urges us to do so. So what you end up with is a conflict between a primitive, atavistic part of your mind which is saying "Jump!" and the more modern, rational part of your mind which is saying, "For Christ's sake, don't!" In fact, vertigo is explained by some not as the fear of falling, but as the temptation to jump!”

“The trouble with most forms of transport, he thought, is basically one of them not being worth all the bother. On Earth — when there had been an Earth, before it was demolished to make way for a new hyperspace bypass — the problem had been with cars. The disadvantages involved in pulling lots of black sticky slime from out of the ground where it had been safely hidden out of harm's way, turning it into tar to cover the land with, smoke to fill the air with and pouring the rest into the sea, all seemed to outweigh the advantages of being able to get more quickly from one place to another — particularly when the place you arrived at had probably become, as a result of this, very similar to the place you had left, i.e. covered with tar, full of smoke and short of fish.”
