What would the Dewey Decimal classification be for The Unknowable? The concept, not anything specific. I imagine in the 0xx's?
001.9 represents controversial knowledge ranging from mysteries to hoaxes to conspiracy theories. Do you make a distinction between the unknown and the unknowable? If not, then 001.9403 is your best bet. Otherwise, I'd check 110 for the metaphysical or 121.2 for the epistemological limits of knowledge (knowing vs believing).
