I think this is very wise and also true. However, I don't think it really goes against what we're saying - or at least what I think we should be trying to say. There are FORMS which get discovered. One form is "story". We know a few things already about how to make a more effective story - stuff that has already been discussed here. On this, actually, there's not really room for "preference", because we aren't talking about individuals. We're talking about guidelines for "what works on people, generally speaking". So, maybe an individual work breaks these rules - and so we might call it bad, by the standards/guidelines that have been discovered - and yet some individuals could still like it. The two things don't conflict. I hope that it's clear by now that this is where we're arguing past each other.
