You can put this another way by saying that while in other sciences the instruments you use are things external to yourself (things like microscopes and telescopes), the instrument through which you see God is your whole self. And if a man's self is not kept clean and bright, his glimpse of God will be blurred - like the Moon seen through a dirty telescope. That is why horrible nations have horrible religions: they have been looking at God through a dirty lens.
C. S. LewisWhen the police arrived and found no lion, no broken wall, and no convicts, and the Head behaving like a lunatic, there was an inquiry into the whole thing. And in the inquiry all sorts of things about Experiment House came out, and about ten people got expelled. After that, the Head's friends saw that the Head was no use as a Head, so they got her made an Inspector to interfere with other Heads. And when they found she wasn't much good even at that, they got her into Parliament where she lived happily ever after.
C. S. LewisThere are a dozen views about everything until you know the answer. Then there's never more than one.
C. S. LewisWe do not want merely to see beauty... we want something else which can hardly be put into words- to be united with the beauty we see, to pass into it, to receive it into ourselves, to bathe in it, to become part of it. That is why we have peopled air and earth and water with gods and goddesses, and nymphs and elves.
