Research

My research focuses on classical Greek and Hellenistic theories of rationality. More specifically, I investigate ancient debate over the rationality of sense-perception. To what extent does, e.g., seeing a cup on the table call upon distinctly rational cognitive resources, such as the ability to use language or apply concepts? What kind of information does sense-perception convey, and how is this information related to the contents of our beliefs? Does expertise affect the qualitative character of perceptual experience? Can we literally perceive ethical properties, such as the property of being courageous or being good? Are there any perceptual experiences which are guaranteed to be true?

The main strand of my research reconstructs the ancient Stoic answers to these questions. However, I also write about Platonic, Platonist, Aristotelian, and Epicurean accounts of the relationship between perception and reason.
