One moment several things are possible, the next moment only one happens, and the rest don't exist. Except that other worlds have sprung into being, on which the did happen.
Philip PullmanI'll be looking for you, Will, every moment, every single moment. And when we do find each other again, we'll cling together so tight that nothing and no one'll ever tear us apart. Every atom of me and every atom of you... We'll live in birds and flowers and dragonflies and pine trees and in clouds and in those little specks of light you see floating in sunbeams... And when they use our atoms to make new lives, they wont' just be able to take one, they'll have to take two, one of you and one of me, we'll be joined so tight.

Philip PullmanHe meant the Kingdom was over, the Kingdom of Heaven, it was all finished. We shouldn't live as if it mattered more than this life in this world, because where we are is always the most important place.... We have to be all those difficult things like cheerful and kind and curious and patient, and we've got to study and think and work hard, all of us, in all our different worlds, and then we'll build... The Republic of Heaven.
