Robert Ziegler

I'm a second-year Ph.D. student in philosophy at the University of Virginia. My main interests are in history of philosophy and metaphysics--and particularly where the two intersect (where, for instance, I'm interested in questions like how Aristotelian hylomorphism bears on contemporary puzzles about material composition, or whether Spinoza's substance monism commits him to ontological pluralism). My main interests in metaphysics include puzzles about identity over time, the relationship between universals and particulars, and questions about material composition. My primary historical interests include Scholasticism, especially Ockham and Scotus, and early-modern philosophy, especially Spinoza and Leibniz.

Outside of metaphysics, significant interests include philosophy of religion, particularly questions about the metaphysics of the divine, metaethics, and questions about what constitutes wellbeing. Otherwise, as a general principle, if someone's called it philosophy, I probably think it's cool.

I have the fortune of having a last name that begins with "Z," so if you ever have trouble finding me in a list, the end is usually the best place to look. If you need to contact me and it isn't related to my position in a list, my email address is
