Kant on race and the radical evil in the human species

Religion within the Boundaries of Mere Reason remains one of the most opaque of Kant's published writings. Though this opacity belongs, partly, to the text itself, a key claim of this article is that this opacity stems also from the narrow lenses through which his readers view this text. Often read as part of Kant's moral philosophy or his universal history, the literature has thus far neglected a different vantage point on the Religion, one that does not refute the utility of these lenses but complements them. This paper places the Religion alongside parts of Kant's corpus that it is less typically paired with, namely his natural history writings—in particular, his writings on the concept of race and the development of the human races. I argue that by doing so, we can shed much light on Kant's infamous claim that there is a radical evil in the human species. More precisely, we will come to appreciate that this evil is not, as it is usually understood, a static property or fixed characteristic of human beings. Instead, radical evil concerns a dynamic, changing defect in human nature that increasingly threatens our aspirations to collective moral perfection.
