Immanuel Kant's views on politics, peace, and history, as expressed in Toward Perpetual Peace and other key writings on these topics, have lost none of their relevance since their publication more than two centuries ago. Indeed, in recent debates on citizenship, globalization, the United Nations, and the role of the state in the post-Cold War world, Kant's philosophy plays a vital role. This volume contains a comprehensive collection of Kant's writings on international relations theory and political philosophy, superbly translated and accompanied by stimulating essays.
