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)

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)

Like previous theorists of natural law, Kant believes in the possibility of a rational theory of ius, but also claims that the very concept of ius naturae and the method of investigation of its principles must be thoroughly reformulated. I will maintain that Kant solves the methodological problem of natural law theories by stating that a rational doctrine of Right concerns pure rational knowledge. Right must be conceived as a metaphysical doctrine in which its principles and laws are determined a (...) priori. By conceiving the idea of a “metaphysics of morals” and linking Right with it, he finds a way both to conserve the notion of ius naturae ) and to purify it from any empirical or anthropological element.

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.

In the Doctrine of Right Kant holds that the classical Ulpian command honeste vive is a juridical duty that has the particular feature of being internal. In this paper I explore the reasons why Kant denies that the duty to be an honorable human being comprises an ethical obligation and conceives it as a juridical duty to oneself. I will argue that, despite the conceptual problems that the systematical incorporation of this type of duty into the doctrine of morals might (...) entail, these reasons are coherent. The fulfillment of the duty honeste vive involves a coercion to the self but at the same time does not necessarily imply the adoption of a moral end. (shrink)

Berthold of Moosburg had the whole Sapientiale by Thomas of York constantly at hand when writing his commentary on Proclus. Even thought Berthold never refers by name to the English Franciscan except in his tabula auctoritatum, where Thomas is registered as «Magister Thomas Anglicus minor», he quotes extensively and verbatim from the Sapientiale throughout his Expositio of Proclus; astoundingly, Berthold quotes more from Thomas than he does from his Dominican predecessors in the Teutonic Province, Albert the Great, Ulrich of Strassburg (...) and Dietrich of Freiberg. The following articles describes the presence of Thomas of York in Berthold of Moosburg’s Expositio super Elementationem theologicam. An appendix provides a systematic investigation of the relationship between the texts of the two authors. (shrink)
