My historical work focuses on issues at the intersection between metaphysics, theology, and philosophy of science in 17th and 18th century European philosophy. A central question that I see tying these areas together for many thinkers in the period is the nature of mental and linguistic representation: how do we manage to think and talk about minds, external objects, God, or the theoretical posits of physics? I am particularly interested in Berkeley, Arnauld, and Leibniz. I have also published on metaphysical issues in analytic philosophy of religion.
