Paul W. Kahn's 'Political Theology: Four New Chapters on the Concept of Sovereignty' delves into the intricate relationship between religious thought and political power in the modern era. Kahn critically examines how theological concepts, even in ostensibly secular societies, continue to shape our understanding of sovereignty, law, and the state. He explores the enduring questions of ultimate authority, legitimacy, and the nature of political obligation, arguing that the divine persists as a shadow within the secular state. This profound work offers fresh perspectives on the challenges facing contemporary political theory and the ongoing search for meaning in a post-sacred world.
