This book examines the various competing interpretations of Kant's foundational Perpetual Peace since its initial publication in the late eighteenth century. According to Easley's analysis, there are two patterns of interpretations: first, the text endorses peace proposals above the state level and second, the text is in favor of peace proposals at the state level. Eric Easley provides a comprehensive historical background and analytical framework for understanding Perpetual Peace, allowing scholars of international relations to better understand and appreciate its complex meaning and see beyond the conventionally accepted interpretations of the day.
