The stories we tell both reveal and shape our worldview. Often, the myths, legends, and fables we share cast a vision of how we would like the world to be, rather than how it actually is. Fairy tales, fantasies, adventure stories — all tend to portray a world in starker contrasts and greater simplicity. The good guys are wholly good. The bad guys are wholly evil. The right course is clear. Events fit a narrative structure. All problems resolve in the end.
