Abstract

_Kant’s Reason_ (2023) is an excellent study that develops an original set of interpretive claims and shows their relevance for contemporary theories of rationality. At the core of Karl Schafer’s project is the following thesis: that Kant’s account of reason is unified as a power of comprehension in both its theoretical and practical activities. The aim of my paper is to examine this thesis against Kant’s doctrine of the Highest Good. In §1, I question some claims Schafer makes about the Highest Good. Then, in §2 and §3, I consider how we might develop a more detailed reading of this doctrine along the lines of Schafer’s project. §4 concludes.
