“We all have common hopes and fears,” I said, “from the lowliest peasant to the king. We dream of someone who will love us more than life itself. In her dreams, every maiden is a princess longing for love; in his dreams, every youth is the one who will win her heart. Even the king’s hopes and fears are as common as our own.”
And that's why fantasy fiction is more honest than realistic fiction: because fantasy fiction deals with archetypes without the pretense that they are more than--or less than--archetypes. You know that Harry Potter isn't a real, living, breathing person; but you also know that his universal need for a family is real. You know it because you've felt it too.
