"As we, in late modernity, grapple with our own theological-political predicament, Victoria Kahn fearlessly interrogates early twentieth-century engagements with many of the early modern authors who gave the religion-politics dilemma its definitive form. Kahn's interpretive moves and conclusions are always enlightening and often exciting. The Future of Illusion is a timely, erudite, and well-argued book that will be an important intervention into contemporary debates over political theology." (John P. McCormick, University of Chicago)"
