“Suppose we have only dreamed, or made up, all of those things-trees and grass and sun and moon and stars and Aslan himself. Suppose we have. Then all I can say is that, in that case, the made-up things seem a good deal more important than the real ones... That's why I'm going to stand by the play world. I'm on Aslan's side even if there isn't any Aslan to lead it. I'm going to live like a Narnian even if there isn't any Narnia.
--Puddleglum, The Silver Chair, C. S. Lewis”
