Catharine Diehl



Postdoctoral Fellow


St. George,


Catharine is a Banting Postdoctoral Fellow for 2017-2019. Her research project, “The Principle of Individuation in Leibniz, Kant, and Contemporary Philosophy” investigates one of the most fundamental questions of metaphysics: in virtue of what is something an individual object? The project undertakes a close study of the principle of individuation in Leibniz’s and Kant’s work and seeks to extract lessons from their debate for contemporary metaphysical inquiry.

Before coming to the University of Toronto, Catharine completed a doctorate in Philosophy at the Humboldt-Universität zu Berlin on “Ontological Nihilism and Existential Commitment: Studies in Metaphysics” (2017), as well as a PhD in Comparative Literature at Princeton University on “The Theory of Intensive Magnitudes in Leibniz and Kant.” She has a BA (magna cum laude) in Philosophy and with honors in Comparative Literature from Brown University (2001).

Her research interests include metaphysics, Kant, Leibniz, and early modern philosophy more generally.
