This may seem like an academic topic but it seems more philosophical to me.
Seriously, what is the point? Why are we analyzing the writer's intent when we cannot know? What's the point of trying to psychoanalyze a writer and trying to figure out what they 'really meant' when they didn't know themselves? How many writers deeply analyze their own writing as much as students in school are forced to? Does analysis of a piece kill it, like how explaining a good joke does?
