 Godehard Link and Harry Bunt have argued that the best models of natural language use of mass expressions will distinguish mass entities from count by treating the former as if they are non-atomic, whether or not they actually are. Godehard Link (1998) argues that the reference of mass expressions is best understood via the development of a rich model-theoretic semantics, which algebraically models the interrelated network of talk of mass, plural, and particular entities. Harry Bunt (1985) subsumes both set theory and mereology into an axiomatic system called “Ensemble Theory” in order to model the structure of talk about mass expressions. Link’s account in particular embraces coincidence on a massive scale.
