I believe that fiction is as much of a reality as any other experience that the reader undertakes. Call it vicarious if you like, but the reader is not a spectator, he is a participant. A novel can make you laugh or cry or go looking for someone you crave. These things are so real they are physiological. Vicarious? Perhaps, but not disembodied.
