I specialize in metaphysics and ontology. I primarily like to think about what there is, parts and wholes, composition, constitution, and modality. I am especially fond of exploring lump theory (or five-dimensionalism), the view that we (and other ordinary objects) are trans-world sums of spatial, temporal, and modal parts. I do not (yet) go so far as to think this view is true, but I certainly think it is worthy of serious philosophical consideration.
I also like to work at the intersection of metaphysics, mind, and language – in particular, mental fictionalism, the view that we are (or should be) fictionalists about mental content.
