the true sun

" This is how I distinguish dreaming and waking. When I am awake I can, in some degree, account for and study my dream. The dragon that pursued me last night can be fitted into my waking world. I know there are such things as dreams...I know that a man of my reading might be expected to dream of dragons. But while in the nightmare I could not have fitted in my waking experience. The waking world is judged more real because it can thus contain the dreaming world; the dreaming world judged less real because it cannot contain the waking one. For the same reason I am certain that in passing from the scientific points of view to the theological, I have passed from dream to waking. Christian theology can fit in science, art, morality and sub-Christian religions. The scientific point of view cannot fit in any of these things, not even science itself. I believe Christianity as I believe that the Sun has risen, not only because I see it, but because by it I see everything else. "

CS Lewis, The Weight of Glory, 139-140
