Published in 1797, the Doctrine of Right is Kant's most significant contribution to legal and political philosophy. As the first part of the Metaphysics of Morals, it deals with the legal rights which persons have or can acquire, and aims at providing the grounding for lasting international peace through the idea of the juridical state (Rechtsstaat). This commentary analyzes Kant's system of individual rights, starting from the original innate right to external freedom, and ending with the right to own property and to have contractual and family claims. Clear and to the point, it guides readers through the most difficult passages of the Doctrine, explaining Kant's terminology, method and ideas in the light of his intellectual environment. One of the very few commentaries on the Doctrine of Right available in English, this book will be essential for anyone with a strong interest in Kant's moral and political philosophy.

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. Ripstein shows that Kant’s thought is organized around two central claims: first, that legal institutions are not simply responses to human limitations or circumstances; indeed the requirements of justice can be articulated without recourse to views about human inclinations and vulnerabilities. Second, Kant argues for a distinctive moral principle, which restricts the legitimate use of force to the creation of a system of equal freedom. Ripstein’s description of the unity and philosophical plausibility of this dimension of Kant’s thought will be a revelation to political and legal scholars. 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. Ripstein defends the idea of equal freedom by examining several substantive areas of law—private rights, constitutional law, police powers, and punishment—and by demonstrating the compelling advantages of the Kantian framework over competing approaches.

For a very long time, Kant’s Doctrine of Right languished in relative neglect, even among those who wanted to defend a Kantian position in political philosophy. Kant’s more interesting claims about politics were often said to be located elsewhere. This anthology examines a wide range of issues discussed by Kant in the Doctrine of Right and other closely related texts, including his views on social contract theory, private property, human rights, welfare and equality, civil disobedience, perpetual peace, forgiveness and punishment, and marriage equality. The authors have all tested Kant’s arguments for possible political application, reaching different and sometimes opposing conclusions. The result is a highly original volume that not only enhances the understanding of Kant’s political philosophy, but also invites substantive debate within the Kantian tradition and beyond.

Past interpreters of Kant’s thought seldom viewed his writings on politics as having much importance, especially in comparison with his writings on ethics, which (along with his major works, such as the Critique of Pure Reason) received the lion’s share of attention. But in recent years a new generation of scholars has revived interest in what Kant had to say about politics. From a position of engagement with today’s most pressing questions, this volume of essays offers a comprehensive introduction to Kant’s often misunderstood political thought. Covering the full range of sources of Kant’s political theory—including not only the Doctrine of Right, the Critiques, and the political essays but also Kant’s lectures and minor writings—the volume’s distinguished contributors demonstrate that Kant’s philosophy offers compelling positions that continue to inspire the best thinking on politics today. Aside from the editor, the contributors are Michaele Ferguson, Louis-Philippe Hodgson, Ian Hunter, John Christian Laursen, Mika LaVaque-Manty, Onora O’Neill, Thomas W. Pogge, Arthur Ripstein, and Robert S. Taylor.

A similar book is Reidar Maliks, Kant’s Politics in Context. Oxford: Oxford University Press 2014, but it does not focus on international law. Pauline Kleingeld’s Kant and Cosmopolitanism: The Philosophical Ideal of World Citizenship, Cambridge: Cambridge University Press 2012 touches upon international relations, but is mainly a book on Kant’s cosmopolitanism, and a comparison with other 18c thinkers.

Immanuel Kant's Metaphysics of Morals (1797), containing the Doctrine of Right and Doctrine of Virtue, is his final major work of practical philosophy. Its focus is not rational beings in general but human beings in particular, and it presupposes and deepens Kant's earlier accounts of morality, freedom and moral psychology. In this volume of newly-commissioned essays, a distinguished team of contributors explores the Metaphysics of Morals in relation to Kant's earlier works, as well as examining themes which emerge from the text itself. Topics include the relation between right and virtue, property, punishment, and moral feeling. Their diversity of questions, perspectives and approaches will provide new insights into the work for scholars in Kant's moral and political theory.
