Kant’s Naturrecht Feyerabend has recently gained more sustained attention for its role in clarifying Kant’s published positions in political philosophy. However, too little attention has been given to the lecture’s relation to Gottfried Achenwall, whose book was the textbook for the course. In this paper, I will examine how Kant rejected and transforms Achenwall’s natural law system in the Feyerabend Lectures. Specifically, I will argue that Kant problematizes Achenwall’s foundational notion of a divine juridical state which opens up a normative (...) gap between objective law and subjective rights. In the absence of a divine sovereign, formal natural law is unable to justify subjective natural rights in the state of nature. In the Feyerabend Lectures, Kant, in order to close this gap, replaces the divine will with the “will of society”, making the state necessary for the possibility of rights. (shrink)

The idea of autonomy, presented as Kant’s main achievement in the Groundwork and the second Critique, is hardly present in the ethics of the “Doctrine of Virtue”. Against Pauline Kleingeld’s recent interpretation, I argue that this does not amount to a disappearance of the Principle of Autonomy, but to an important development of the notion of autonomy. I first show that Kant still advocated the Principle of Autonomy in the 1790s along with the thought of lawgiving through one’s maxims. I (...) then argue that the role of autonomy in Kant’s later ethics has a different focus than in the previous works, which requires to connect autonomy with autocracy. Conversely, in the “Doctrine of Virtue”, autocracy, which Kant had employed before as an independent notion, is construed as a new layer of autonomy. What Kant there calls subjective autonomy is thereby considered as reason’s self-government in the maxims of each rational agent. -/- . (shrink)

Within Kantian ethics and Kant scholarship, it is widely assumed that autonomy consists in the self-legislation of the principle of morality. In this paper, we challenge this view on both textual and philosophical grounds. We argue that Kant never unequivocally claims that the Moral Law is self-legislated and that he is not philosophically committed to this claim by his overall conception of morality. Instead, the idea of autonomy concerns only substantive moral laws, such as the law that one ought not (...) to lie. We argue that autonomy, thus understood, does not have the paradoxical features widely associated with it. Rather, our account highlights a theoretical option that has been neglected in the current debate on whether Kant is best interpreted as a realist or a constructivist, namely that the Moral Law is an a priori principle of pure practical reason that neither requires nor admits of being grounded in anything else.
