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)

This article examines Kant’s theory of property through a comparative analysis of Gottfried Achenwall’s justification of ownership rights. I argue that at the core of Achenwall’s and Kant’s understanding of ownership rights lies the idea that rights are to be acquired through a juridical act (factum iuridicum, rechtlichen Act) of the will. However, while Achenwall thinks of this act as emerging from a private will, Kant holds that rights and obligations can only be brought about by an (...) act of the general will. By contrasting these two views, I aim to illuminate one of the main features of Kant’s theory of property, namely, that ownership rights are only possible in a rightfully constituted state. I conclude with a suggestion regarding Kant’s view of the notion of ‘provisional’ possession in the state of nature. (shrink)

I argue that by considering Kant’s engagement with previous theorists of natural right, we can gain a clearer understanding of how he transformed the discipline from its foundations. To do this, I focus my analysis on Kant’s (critical) reception of two models of natural right with which he was very familiar: one from Alexander Baumgarten’s Elements of First Practical Philosophy [Initia philosophiae practicae primae], the other from Gottfried Achenwall’s Natural Law [Ius naturae]. The Initia served as a basis for (...) Kant’s lectures on moral philosophy for over three decades and may thus be considered as having played an important role in shaping his practical philosophy as a whole. Achenwall’s Ius naturae was the textbook that Kant employed in his lectures on natural right for over two decades. I argue that Kant distances himself from previous models of natural right in three main regards: the identification of moral laws with laws of nature, the normative connection between the principles of right and a natural end, and the place of God as the author of moral laws. I then briefly discuss what Kant retains of Baumgarten’s and Achenwall’s models of natural right. Kant’s Metaphysics of Morals preserves the view that a rational doctrine of right belongs to a broader systematic doctrine that comprehends the entire system of duties. I address the question of the division of the Sittenlehre into two branches and claim that, whereas Kant did not consider Baumgarten’s answer to the problem of distinguishing juridical from ethical principles to be satisfactory, he found a key piece of his own resolution in Achenwall’s Ius naturae, namely the definition of right as a power to coerce.

Kant clearly endorses some version of the ‘old formula of the schools’, according to which all volition is sub ratione boni. There has been a debate whether he holds this only for morally good actions. I argue that a closer look at the distinction between the good and the agreeable does not support this conclusion. Considering Kant’s account of the detrimental and the correct use of this thesis, I argue that rational beings always will sub ratione boni, even when they (...) act immorally, because they act on principles. I argue that Kant’s accounts of self-love and self-conceit support this view. (shrink)

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.

In this paper I examine the relationship between the principle of right and the principle of morals [Sitten] in Kant’s Metaphysics of Morals. My interpretation denies that the principle of right is derived from the categorical imperative, but neither does it adhere to the independence thesis. I present a third way of understanding the relationship between the law of right and the universal law of morals: the latter is needed in order to formulate the former, but it is not sufficient. (...) The principle of right is obtained by applying the categorical imperative to the concept of right. I highlight the discussion on the subject within the late eighteenth-century German natural law tradition and similar arguments found in Achenwall. (shrink)
