The Subterfuge of Realism

Admitted fantasy is precisely the kind of literature which never deceives at all. Children are not deceived by fairy-tales; they are often and 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 us are 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 or anti-religious ‘comment on life.
