A literature professor might ask: What happens when you see Hamlet in terms of Dennett"s epistemology as opposed to the epistemology of Aristotele?

If you want to ask that question it doesn't matter whether the epistemologies are true.

And if you want to ask the question of whether a yeti could defeat a Mongolian death worm it doesn't matter whether they exist. What is the purpose of seeing Hamlet in terms of this or that epistemology?
