Abstract

Thomasson is a simple realist about the vast majority of entities: she thinks that they exist, and that their existence is to be accepted as a trivial consequence of the truth of various uncontroversial sentences (Thomasson, Ontology Made Easy. Oxford: Oxford University Press, 2015, p. 156). This position is to be taken in contrast to the explanatory realism familiar from dominant post-Quinean metaontology: the view that entities are posited to explain phenomena, and that (very roughly) we should believe in whatever we need in order for our best scientific theories to come out as true. Recent literature further suggests an approach I’ll call ‘fundamentality realism’: the idea that we should understand realism in connection with notions of fundamentality and metaphysical priority. I introduce these notions and the relations between them before describing an objection to Thomasson-style simple realism. I argue that this objection can be overcome by combining simple realism with elements of fundamentality realism, and that such a view can nevertheless be seen to fit with Thomasson's overall metaphysical worldview.
