The paper examines Schiller’s argument concerning the subjective experience of adopting a morality based on Kantian principles. On Schiller’s view, such experience must be marked by a continuous struggle to suppress nature, because the moral law is a purely rational and categorically commanding law that addresses beings who are natural as well as rational. Essential for Schiller’s conclusion is the account he has of what it takes to follow the law, that is, the mental states and functions that encapsulate the (...) idea of moral self contained in Kant’s ethics. Focusing on the fundamental psychological elements and processes to which Kant’s theory appeals and on which it depends to have application, the paper defends an alternative idea of moral self to the one Schiller attributes to Kant.
