bq. This article surveys recent work on Kant’s _Critique of Practical Reason_, with a particular focus on his doctrine of the fact of reason and his doctrine of the practical postulates, assessing the implications of such work for the debate about realism and antirealism in Kant’s moral philosophy. Section 1 briefly surveys some salient considerations raised by Kant’s first _Critique_ and _Groundwork_. In section 2, I survey recent work on the Kant’s doctrine of the fact of reason and argue that it does not support an anti-realist interpretation of Kant’s ethics. In section 3, I argue that recent work on Kant’s doctrine of the practical postulates does not support an anti-realist interpretation of Kant’s ethics.
