“We are an impossibility in an impossible universe.”

“Science fiction is the art of the possible not the impossible.”

“From this outer edge of his life, looking back, there was only one remorse, and that was only that he wished to go on living. Did all dying people feel this way, as if they had never lived? Did life seem that short, indeed, over and done before you took a breath? Did it seem this abrupt and impossible to everyone, or only to himself, here, now, with a few hours left to him for thought and deliberation?”

“We have everything we need to be happy but we aren't happy. Something is missing...It is not books you need, it's some of the things that are in books. The magic is only in what books say, how they stitched the patches of the universe together into one garment for us.”

“Books were only one type of receptacle where we stored a lot of things we were afraid we might forget. There is nothing magical in them at all. The magic is only in what books say, how they stitched the patches of the Universe together into one garment for us.”

“How like a mirror, her face. Impossible; for how many people did you know who refracted your own light to you?

“Science fiction is the fiction of ideas. Ideas excite me, and as soon as I get excited, the adrenaline gets going and the next thing I know I’m borrowing energy from the ideas themselves. Science fiction is any idea that occurs in the head and doesn’t exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. As soon as you have an idea that changes some small part of the world you are writing science fiction. It is always the art of the possible, never the impossible.”
