It is good that the window should be transparent, because the street or garden beyond it is opaque. How if you saw through the garden too? It is no use trying to 'see through' [everything]. If you see through everything, then everything is transparent. But a wholly transparent world is an invisible world. To 'see through' all things is the same as not to see.
C. S. LewisThe whole journey was odd and dream-like -- the roaring stream, the wet grey grass, the glimmering cliffs which they were approaching, and always the glorious, silently pacing beast ahead.
C. S. LewisA man's physical hunger does not prove that man will get any bread; he may die of starvation on a raft in the Atlantic. But surely a man's hunger does prove that he comes of a race which repairs its body by eating and inhabits a world where eatable substances exist. In the same way, though I do not believe (I wish I did) that my desire for Paradise proves that I shall enjoy it, I think it a pretty good indication that such a thing exists and that some men will.
C. S. LewisA perfect man would never act from a sense of duty; heโd always want the right thing more than the wrong one. Duty is only a substitute for love (of God and of other people) like a crutch which is a substitute for a leg. Most of us need the crutch at times; but of course it is idiotic to use the crutch when our own legs (our own loves, tastes, habits etc.) can do the journey on their own.
