In this masterful work, both an illumination of Kant's thought and an important contribution to contemporary legal and political theory, Arthur Ripstein gives a comprehensive yet accessible account of Kant's political philosophy. In addition to providing a clear and coherent statement of the most misunderstood of Kant's ideas, Ripstein also shows that Kant's views remain conceptually powerful and morally appealing today.

The central claim of Kant's political philosophy is that rational agents sharing a territory can justifiably be forced to live under a state; they have, in Kant's words, a duty of right to leave the state of nature. Perhaps something along these lines is entailed by any theory of state legitimacy, but the point raises special difficulties for Kant. He believes that rational agents have a right to freedom; that is, he believes that a rational agent's external freedom - her (...) ability to set and pursue ends for herself without being subject to the choices of others - can justifiably be restricted only for the sake of external freedom itself. To establish that human beings can be forced to join a civil condition, it will therefore not do to show that the state promotes security, prosperity or any other such value: Kant has to show that human beings living side by side need a state to be free.

I argue that the freedom which is to coexist with the freedom of choice of others in accordance with a universal law mentioned in Kant's Rechtslehre is not itself freedom of choice. Rather, it is the independence which is a condition of being able to exercise genuine free choice by not having to act in accordance with the choices of others. Kant's distinction between active and passive citizenship appears, however, to undermine this idea of independence, because the possession of a (...) certain type of property right on the part of some citizens makes it possible for them to dominate others. Kant's account of property in this way turns out to be central to the question as to whether his Rechtslehre represents an internally consistent account of how freedom can be guaranteed within a legal and political community. I go on to argue that Kant's attempt to justify a pre-political right of property cannot be viewed as a successful justification of private property, and that he should have abandoned the notion of su...
