Stories have a way of conveying truth on a level that is so intuitive that it feels like remembering, rather than learning. Fairy tales tend to do this, but in an even more honest, and authentic way. For it is far harder to trick children, unless you first make them grow up, forgetting the things they were born knowing.
As I have read faerie tales, I have found that many authors don’t have a very high opinion of growing up.
