Facet and Appearance

A 'facet' can be defined as an 'external surface'.  So, insofar as 'in itself' means 'independent of another entity', a thing in itself can possess a surface.  Now, a Facet qua perceived can be classified as an 'Appearance'.  Thus, the 'object' of an empirical perception is, in one sense, a Facet, while in another, an Appearance.  So, insofar as a Facet is an object of an empirical perception, it is not a mere 'object of thought'. as Kant classifies it.  Likewise, a 'thing in itself' is not necessarily an intellectual operation, as Kant later asserts.
