Kant’s Rechtslehre is concerned with the freedom that is to coexist with the freedom of choice of others in accordance with a universal law. I argue that this freedom is not to be directly equated with freedom of choice: it is instead the independence that is a condition of genuine free choice because it ensures that one is not constrained to act in accordance with the choices of others. Kant’s distinction between active and passive citizenship, however, is incompatible with this notion of independence because property rights of a certain type make it possible for some citizens to dominate other citizens, who cannot, therefore, be classed as genuinely independent. Thus the concept of property is central to the question of how right can secure the freedom of citizens. I show that Kant understands this concept in terms of a relation between persons with respect to things, rather than in terms of only a relation between a person and a thing. I argue that although Kant appears to argue in favour of private property, he does not sufficiently justify this form of property by demonstrating that other forms of property would be less compatible with the freedom that right is to secure and guarantee.
