“Time and space were, from Death's point of view, merely things that he'd heard described. When it came to Death, they ticked the box marked Not Applicable. It might help to think of the universe as a rubber sheet, or perhaps not.”
― Terry Pratchett, Hogfather

“Knowledge equals power...
The string was important. After a while the Librarian stopped. He concentrated all his powers of librarianship.
Power equals energy...
People were stupid, sometimes. They thought the Library was a dangerous place because of all the magical books, which was true enough, but what made it really one of the most dangerous places there could ever be was the simple fact that it was a library.
Energy equals matter...
He swung into an avenue of shelving that was apparently a few feet long and walked along it briskly for half an hour.
Matter equals mass.
And mass distorts space. It distorts it into polyfractal L-space.
So, while the Dewey system has its fine points, when you're setting out to look something up in the multidimensional folds of L-space what you really need is a ball of string.”

“It is hard to talk about the importance of an imaginary hero. But heroes are important. Heroes tell us something about ourselves. History books tell us who we used to be, documentaries tell us who we are now... but heroes, tell us who we want to be. A lot of our heroes depress me. But when they made this particular hero, they didn't give him a gun, they gave him a screwdriver to fix things. They didn't give him a tank or a warship or a X-Wing Fighter, they gave him a phone box from which you can call for help. And they didn't give him a superpower, or pointy ears, or Heat Ray, they gave him an extra heart. They gave him two hearts and that is an extraordinary thing. There will never come a time when we don't need a hero like the Doctor.

“A philosopher once asked, "Are we human because we gaze at the stars, or do we gaze at them because we are human?" Pointless, really..."Do the stars gaze back?" Now, that's a question.”
― Neil Gaiman, Stardust
