We read books to find out who we are. What other people, real or imaginary, do and think and feel—or have done and thought and felt; or might do and think and feel—is an essential guide to our understanding of what we ourselves are and may become. A person who had never known another human being could not be introspective, any more than a terrier can, or a horse; he might (improbably) keep himself alive, but he could not know anything about himself, no matter how long he lived with himself. And a person who had never listened to nor read a tale or myth or parable or story, would remain ignorant of his own emotional and spiritual heights and depths, would not know quite fully what it is to be human. For the story—from Rumpelstiltskin to War and Peace—is one of the basic tools invented by the mind of man, for the purpose of gaining understanding. There have been great societies that did not use the wheel, but there have been no societies that did not tell stories.
