“If life is going to exist in a Universe of this size, then the one thing it cannot afford to have is a sense of proportion.”

“To Trin Tragula's horror, the shock completely annihilated her brain; but to his satisfaction he realized that he had proved conclusively that if life is going to exist in a Universe of this size, then the one thing it cannot afford to have is a sense of proportion.”

“The chances of finding out what’s really going on in the universe are so remote, the only thing to do is hang the sense of it and keep yourself occupied.”

“The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair.”

“The problem is, or rather one of the problems, for there are many, a sizeable proportion of which are continually clogging up the civil, commercial, and criminal courts in all areas of the Galaxy, and especially, where possible, the more corrupt ones, this.The previous sentence makes sense. That is not the problem.This is:Change.Read it through again and you'll get it.”

“It is folly to say you know what is happening to other people. Only they know, if they exist. They have their own Universes of their own eyes and ears.”

“But that can't work, can it?" Said Richard. "If we do that, then this won't have happened. Don't we generate all sorts of paradoxes?"Reg stirred himself from thought. "No worse than many that exist already," he said. "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 its 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. That isn't to say if you get involved in a paradox a few things won't strike you as being very odd, but if you've got through life without that already happening to you, then I don't know which universe you've been living in, but it isn't this one”
