Abstract
The chapter deals with the two most distinctive elements of the Introduction of the Naturrecht Feyerabend, namely the notions of an end in itself and autonomy. I shall argue that both are to be interpreted with regard to the aim of explaining the ground of right. In this light, I suggest that the notion of an end in itself counters a voluntarist conception like Achenwall’s with a claim whose necessity has a twofold ground: First, the representation of an unconditional worth emerges as a structural element of the practical use of reason. Second, that representation concerns the necessary self-understanding of moral subjects. Finally, I argue that the other distinctive element, the occurrence of the notion of autonomy, is best understood as an application of that idea to a specific issue, which Kant addresses by showing that freedom is a self-regulating domain.
