Immanuel Kant’s views on politics, peace, and history have lost none of their relevance since their publication more than two centuries ago. This volume contains a comprehensive collection of Kant’s writings on international relations theory and political philosophy, superbly translated and accompanied by stimulating essays. Pauline Kleingeld provides a lucid introduction to the main themes of the volume, and three essays by distinguished contributors follow: Jeremy Waldron on Kant’s theory of the state; Michael W. Doyle on the implications of Kant’s political theory for his theory of international relations; and Allen W. Wood on Kant’s philosophical approach to history and its current relevance.
