Abstract

This chapter aims to show that there is a general theory of social ontology implicit in Amie Thomasson’s prolific philosophical work. In contrast to her books on fiction and metaphysics, this theory is not argued for in a single volume. The first objective is thus to make Thomasson’s important contribution to social ontology explicit by drawing out its core features. Despite its many advantages, such as its ability to take abstract social objects into account, there is a central difficulty: Thomasson’s new account of social groups is too narrow since it cannot accommodate opaque kinds of social groups. The second and related aim is to develop this objection and demonstrate that it must be resolved before we can take Thomasson’s theory of social ontology fully onboard. The chapter closes by suggesting that we can overcome this objection by even more pluralism—already a core feature in Thomasson’s social ontology.
