We have not even to risk the adventure alone, for the heroes of all time have gone before us.  The labyrinth is fully known.  We have only to follow the thread of the hero-path, and where we had thought to find an abomination, we shall find a god.  And where we sought to slay another, we shall slay ourselves.  Where we had thought to travel outward, we will have come to the center of our  existence.  And where we had thought to be alone, we shall be with all the world.

— Joseph Campbell
