His books include Kant's Transcendental Proof of Realism (Cambridge, 2004), How Hume and Kant Reconstruct Natural Law: Justifying Strict Objectivity without Debating Moral Realism (Clarendon, 2016), Grounds of Pragmatic Realism: Hegel's Internal Critique and Transformation of Kant's Critical Philosophy (Brill, 2018), Hegel's Civic Republicanism: Integrating Natural Law with Kant's Moral Constructivsm (Routledge, 2020) and Kant's Critical Epistemology: Why Epistemology must Consider Judgment First (Routledge, 2020). He is researching systematically history and philosophy of law, especially Montesquieu, G.W.F. Hegel and Rudolf von Jhering, to develop a cogent normative sociological theory of law and justice.
