but after we used it as applied to HPMOR and Atlas Shrugged - or parable fiction in general -

What has aesthetics got to do with HPMOR and AS?

I've been using it in justifications of reading (certain) fiction now, but I want to be careful that I'm not talking about something else, or something that doesn't exist, so my rationality can aim true.

Just taboo all the weird terms, and be specific. What are you reading and why?
