I am a philosopher working in metaethics, philosophy of mind, epistemology, and metaphysics. In metaethics I work on the moral error theory, and in particular on whether the requirement that our moral commitments be consistent still holds once we accept that all of them are false. In the philosophy of mind I defend the Spinozan theory of belief fixation, on which belief is the automatic result of merely entertaining a proposition rather than the outcome of deliberation. 

In epistemology I work on the Myth of the Given and the structure of epistemic justification, including the debates between foundationalism and coherentism and between internalism and externalism. In metaphysics I work on abstract objects, idealism, and the existence of God.
