This is one of the best books on Kant's legal philosophy to appear to date. It is both an outstanding commentary on Kant and an important work of legal-political philosophy with much contemporary relevance. What is perhaps most impressive about this book is how much unity it uncovers in Kant's legal and political thought.

This masterful treatment of Kant's legal and political philosophy gets to the heart of Kant's endeavor and its virtues with wonderful clarity--a terrific achievement. We learn from Ripstein both how Kant's legal and political philosophy is best understood and how this philosophy can be defended and employed in ongoing philosophical debates. I regard this as the very best kind of approach to the history of philosophy.

One sunny spring day nearly forty years ago, I was sitting in an open air café in Ithaca, New York, having coffee with Hans-Georg Gadamer… Gadamer said that the biggest single lacuna in Kant studies was the absence of a really good book on Kant's Rechtslehre. It ought to be a book, he declared, that did not start out from Kantian ethics, but instead expounded Kant's theory of human rights, law and politics authentically, solely on the ground of Kant's concept of Recht: external freedom according to universal law… Until now, however, I have never found the book Gadamer thought so badly needed to be written. But this book finally appears to be it.

Force and Freedom is arguably the best book ever written on Kant’s legal and political philosophy.

There can be little doubt that this is the book against which all other interpretations of Kant’s legal and political theory will be measured.

A prominent feature of the landscape in moral philosophy and its history during the past forty years has been the simultaneous flowering of scholarship on Kant, alongside Kantian approaches to contemporary ethical theory. Kant’s legal and political philosophies have fared less well, however. With some notable exceptions, they have attracted less sustained scholarly interest and inspired nothing like the contributions to current debates of Kantian moral philosophers such as Herman, Hill, and Korsgaard. Arthur Ripstein’s Force and Freedom goes a long way to redressing this imbalance. It provides both a beautifully clear and insightful interpretation of the relevant Kantian texts as well as a sympathetic and forceful presentation of their central claims and arguments as Ripstein interprets them. It is a remarkable achievement.
