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)

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.
