Gideon Rosen

Gideon Rosen is the Stuart Professor of Philosophy at Princeton University, where he has been a faculty member since 1993. He holds a Ph.D. from Princeton (1992) and previously taught at the University of Michigan. His research focuses on metaphysics, epistemology, and moral philosophy, with notable contributions to debates in metaethics, normative ethics, and the philosophy of mathematics. Rosen co-authored A Subject With No Object (1997) and co-edited The Norton Introduction to Philosophy (2015). He served as Chair of Princeton’s Council of the Humanities from 2006 to 2014 and currently directs the Behrman Undergraduate Society of Fellows.

Rosen’s work interrogates foundational questions in metaphysics, such as the nature of ontological dependence, modal status of moral principles, and the relationship between normative necessity and epistemic justification. His recent publications address accountability in ethics, implicit bias, and fictionalist approaches to metaphysical and mathematical entities. His scholarship bridges analytic philosophy’s core areas while engaging with contemporary issues in moral psychology and legal theory.

Rosen’s academic leadership includes roles in university governance and undergraduate mentorship through the Behrman Society. His writing combines rigorous argumentation with accessible exposition, evident in his textbook contributions and critical analyses of peers like Tim Scanlon and Judith Jarvis Thomson.
