“There are many horrible sights in the multiverse. Somehow, though, to a soul attuned to the subtle rhythms of a library, there are few worse sights than a hole where a book ought to be.”

“The gods of the Disc have never bothered much about judging the souls of the dead, and so people only go to hell if that's where they believe, in their deepest heart, that they deserve to go. Which they won't do if they don't know about it. This explains why it is so important to shoot missionaries on sight.”

“It looked like the sort of book described in library catalogues as 'slightly foxed', although it would be more honest to admit that it looked as though it had been badgered, wolved and possibly beared as well.”

“It is a well-known established fact throughout the many-dimensional worlds of the multiverse that most really great discoveries are owed to one brief moment of inspiration. There's a lot of spadework first, of course, but what clinches the whole thing is the sight of, say, a falling apple or a boiling kettle or the water slipping over the edge of the bath. Something goes click inside the observer's head and then everything falls into place. The shape of DNA, it is popularly said, owes its discovery to the chance sight of a spiral staircase when the scientist‘s mind was just at the right receptive temperature. Had he used the elevator, the whole science of genetics might have been a good deal different.This is thought of as somehow wonderful. It isn't. It is tragic. Little particles of inspiration sleet through the universe all the time traveling through the densest matter in the same way that a neutrino passes through a candyfloss haystack, and most of them miss.Even worse, most of the ones that hit the exact cerebral target, hit the wrong one.For example, the weird dream about a lead doughnut on a mile-high gantry, which in the right mind would have been the catalyst for the invention of repressed-gravitational electricity generation (a cheap and inexhaustible and totally non-polluting form of power which the world in question had been seeking for centuries, and for the lack of which it was plunged into a terrible and pointless war) was in fact had by a small and bewildered duck.By another stroke of bad luck, the sight of a herd of wild horses galloping through a field of wild hyacinths would have led a struggling composer to write the famous Flying God Suite, bringing succor and balm to the souls of millions, had he not been at home in bed with shingles. The inspiration thereby fell to a nearby frog, who was not in much of a position to make a startling contributing to the field of tone poetry.Many civilizations have recognized this shocking waste and tried various methods to prevent it, most of them involving enjoyable but illegal attempts to tune the mind into the right wavelength by the use of exotic herbage or yeast products. It never works properly.”

“It was also a room full of books and made of books. There was no actual furniture; this is to say, the desk and chairs were shaped out of books. It looked as though many of them were frequently referred to, because they lay open with other books used as bookmarks.”

“at least nine-tenths of all the original reality ever created lies outside the multiverse, and since the multiverse by definition includes absolutely everything that is anything, this puts a bit of a strain on things.Outside the boundaries of the universes lie the raw realities, the could-have-beens, the might-bes, the never-weres, the wild ideas, all being created and uncreated chaotically like elements in fermenting supernovas.Just occasionally where the walls of the worlds have worn a bit thin, they can leak in.”

“That bit where that lad sprang backwards right across the room with them axes in his hands was impressive, though.""Yeah.""You didn't ought to have stuck your sword out like that, I thought.""He's learned an important lesson.""It won't do him much good now where he's gone.”
