Groups––A Semantic and Metaphysical Examination

(Supervisors: Josh Dever and Mark Sainsbury)

Short Dissertation Abstract: This manuscript is focused on the extent to which semantics can guide metaphysics. I argue that, at best, semantics can serve as a partial guide to metaphysics. Sometimes there will be indeterminate answers to questions of the form 'Does theory T carry a commitment to Fs?' Further, semantics will never answer questions regarding the nature of Fs.

In it I apply this methodology to plurals (e.g., 'the girls,' 'Tom, Luke and George') and collective nouns (e.g., 'the team,' 'a committee'). I argue that plurals are indeterminately committed to sums (or other singular entities) while collective nouns are determinately committed to groups. The semantics of collective nouns delivers the minimal verdict that groups exist, but says nothing about their nature. I also undertake an examination of the metaphysics of groups which goes beyond semantics to offer a substantive view of the metaphysics of groups.
