I work on ancient Greek philosophy, focusing in the areas of metaphysics and epistemology. My recent research is on Plato’s metaphysics and the topic of "self-predication". Scholars have often criticized Plato for holding the view that all forms “self-predicate”. For instance, they see Plato as holding that the form of tallness is itself a tall thing, which appears to conflict with his other views about forms. I defend Plato against such a criticism, arguing that he is not committed to any self-predication assumption. Relying on contemporary work in linguistics and evidence from ancient texts, I develop a new interpretation of Plato’s use of predication that avoids the difficulties associated with self-predication. I also have a current project in Modern philosophy, which focuses on the topic of the evil deceiver and free will in Descartes.
