“This seems to me the most fundamental difference between the Christian and the unbeliever in their approach to literature. But I think there is another. The Christian will take literature a little less serious than the cultured Pagan: he will feel less uneasy with a purely hedonistic standard for at least many kinds of work. The unbeliever is always apt to make a kind of religion of his aesthetic experiences; he feels especially irresponsible, perhaps, but he braces his strength to receive responsibilities of another kind which seem to the Christian quite illusory. He has to be ‘creative’; he has to obey a mystical law called his artistic conscience; and he commonly wishes to maintain his superiority to the great mass of mankind who turn to books for mere recreation. But the Christian knows from the outset that the salvation of a single soul is more important than the production and preservation of all the epics and tragedies in the world: and as for superiority, he knows that the vulgar, since they include most the poor, probably include most of his superiors. He has no objection to comedies that merely amuse and tales that merely refresh; for he thinks like Thomas Aquinas…We can play, as we can eat, to the glory of God.”
-C.S. Lewis, “Christianity and Literature” (195-196)
"Those who wish to be deceived always demand in what they read at least a superficial or apparent realism of content...[Without] at least some degree of realism in content...no deception will occur at all. No one can deceive you unless he makes you believe he is telling the truth. The unblushingly romantic has far less power to deceive than the apparently realistic. Admitted fantasy is precisely the kind of literature that never deceives at all. Children are not deceived by fairy-tales; they are often gravely deceived by school-stories. Adults are not deceived by science-fiction; they can be deceived by the stories in the women's magazines. None of is deceived by The Odyssey, the Kalevala, Beowulf, or Malory. The real danger lurks in sober-faced novels where all appears to be very probable but all is in fact contrived to put across some social or ethical or religious 'comment on life.'"
--C.S. Lewis, An Experiment in Criticism (1961 A.D.)
