On carcinisation for the soul, and constrained optimisation
Something I think that is missed here is that these are not the shapes of our stories, but of our narratives. A story doesn't need to conform to any of these (e.g. if I tell you a story about my day, I'm unlikely to truly conform to any of these), but a narrative absolutely would. If I want to tell you how I've become successful, it's going to take a narrative form, because I have a goal. These are often conflated, but are, in fact, distinct concepts.
Maybe some of the similarity of the Greek, Norse and Indian myths are a common Indo European origin. Is there rally much similarity of the with the Mesopotamian myths?
