 The relatively orthodox reactions to ‘stuff’ (or ‘matter’) as opposed to ‘things’ in contemporary analytic metaphysics is to either ignore stuff, reduce stuff to things, or eliminate stuff from one’s ontology. These reactions are required by the previous embrace of what we could call ‘Thing Theory.’ Thing Theory, very roughly, is the view that (excluding properties and  relations)[1],  all concrete existents are either things fundamentally, or reducible to fundamental things.
