Sean M. Costello

Sean M. Costello is a doctoral candidate in Philosophy, where he is working on early modern philosophy. He is writing a dissertation titled 'Early Modern Dualisms and Unities of Consciousness' – focusing on Descartes, Henry More, and Samuel Clarke. Tad Schmaltz is the chair of his committee.

He holds an undergraduate degree in philosophy from the University of Notre Dame and a master’s degree in ancient philosophy from the University of Oxford (Hertford College).

His primary research interests lie in understanding, through the lens of the history of philosophy, how the world metaphysically is and how it is that we, as living beings, navigate and psychologically experience it. In addition to his dissertation, Sean's current work focuses on issues regarding perception, memory, and consciousness in the writings of figures in the early modern period, such as Descartes, Henry More, Anne Conway, Samuel Clarke, and Émilie Du Châtelet. He has also done work in ancient and medieval philosophy, on figures such as Plato, Aristotle, Chrysippus, and Aquinas.
