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. LewisA faith in culture is as bad as a faith in religion; both expressions imply a turning away from those very things which culture and religion are about. Culture as a collective name for certain very valuable activities is a permissible word; but culture hypostatized, set up on its own, made into a faith, a cause, a banner, a platform, is unendurable. For none of the activities in question cares a straw for that faith or cause. It is like a return to early Semitic religion where names themselves were regarded as powers.
C. S. LewisSuppose... suppose we have only dreamed and made up these things like sun, sky, stars, and moon, and Aslan himself. In that case, it seems to me that the made-up things are a good deal better than the real ones. And if this black pits of a kingdom is the best you can make, then it's a poor world. And we four can make a dream world to lick your real one hollow.
C. S. LewisHeaven is reality itself. All that is fully real is Heavenly. For all that can be shaken will be shaken and only the unshakeable remains.
C. S. LewisChronological snobbery is the uncritical acceptance of the intellectual climate common to our own age and the assumption that whatever has gone out of date is on that account discredited. You must find why it went out of date. Was it ever refuted (and if so by whom, where, and how conclusively), or did it merely die away as fashions do? If the latter, this tells us nothing about its truth or falsehood.
