Joseph Campbell (The Hero with a Thousand Faces)

"Furthermore, we have not even to risk the adventure alone; for the heroes of all time have one 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; where we had thought to slay another, we shall slay ourselves; where we had thought to travel outward, we shall come to the center of our own existence; where we had thought to be alone, we shall be with all the world."
