“Reality is not digital, an on-off state, but analog. Something gradual. In other words, reality is a quality that things possess in the same way that they possess, say, weight. Some people are more real than others, for example. It has been estimated that there are only about five hundred real people on any given planet, which is why they keep unexpectedly running into one another all the time.”

“It's amazing how good governments are, given their track records in almost every other field, at hushing up things like alien encounters. One reason may be that the aliens themselves are too embarrassed to talk about it. It's not known why most of the space-going races of the universe want to undertake rummaging in Earthling underwear as a prelude to formal contact. But representatives of several hundred races have taken to hanging out, unsuspected by one another, in rural corners of the planet and, as a result of this, keep on abducting other would-be abductees. Some have been in fact abducted while waiting to carry out an abduction on a couple of aliens trying to abduct the aliens who were, as a result of misunderstood instructions, trying to form cattle into circles and mutilate crops. The planet Earth is now banned to all alien races until they can compare notes and find out how many, if any, real humans they have actually got. It is gloomily suspected that there is only one - who is big, hairy, and has very large feet. The truth may be out there, but the lies are inside your head.”

“No other library anywhere, for example, has a whole gallery of unwritten books - books that would have been written if the author hadn't been eaten by an alligator around chapter 1, and so on. Atlases of imaginary places. Dictionaries of illusory words. Spotter's guides to invisible things. Wild thesauri in the Lost Reading Room. A library so big that it distorts reality and has opened gateways to all other libraries, everywhere and everywhen...”

“There was, he thought, probably something in the idea that there were only a few people in the world. There were lots of bodies, but only a few people. That's why you kept running into the same ones.”

“Time was something that largely happened to other people; he viewed it in the same way that people on the shore viewed the sea. It was big and it was out there, and sometimes it was an invigorating thing to dip a toe into, but you couldn't live in it all the time. Besides, it always made his skin wrinkle.”

“...there was a general murmuring, no real words, nothing that would get anyone into trouble if the piper turned nasty, but a muttering indicating, in a general sense, without wishing to cause umbrage, and seeing everyone's point of view, and taking one thing with another, and all things being equal, that people would like to see the boy given a chance, if it's all right with you, no offence meant.”

“They called themselves the Munrungs. It meant The People, or The True Human Beings.It's what most people call themselves, to begin with. And then one day the tribe meets some other People or, if it's not been a good day, The Enemy. If only they'd think up a name like Some More True Human Beings, it'd save a lot of trouble later on”
