Gideon Rosen is a contemporary analytic philosopher at Princeton University, where he is the Stuart Professor of Philosophy. He works primarily in metaphysics, metaethics, and philosophy of mathematics, with influential contributions to the theory of moral responsibility, mathematical nominalism, and the metaphysics of grounding and essence.
Developed a widely discussed account of moral blameworthiness and the conditions under which agents are responsible for wrongdoing
Contributed to mathematical fictionalism and nominalism, arguing that mathematical objects need not be taken as real
Advanced work on metaphysical grounding, essence, and the structure of explanatory priority
Explored modal epistemology and the limits of conceivability as a guide to possibility
Applied metaethical analysis to moral obligation, normative explanation, and the nature of wrongness
The lack of informativeness is not a good objection to the optimalist account of negative truths
