"What's made up in the head is the fiction. What comes out of the heart is a myth."
Joseph Campbell, The Hero's Journey (Copyright © 1990, 2003 Joseph Campbell Foundation p. 73; Copyright © 2014 Joseph Campbell Foundation, paperback edition) p. 90
There are many fans of Joseph Campbell's myth theories. For example Clint Eastwood.
Never read the book. I suppose it it just his opinion, he is putting a definition on something quite nebulous because it is about feelings which are very subjective.
I always scratch my head wondering what in the heck Campbell is talking about.
I hadn't thought about it this way. I read the book, but it was a long time ago.
