This book, by one of the most prominent interpreters of Leo Strauss's thought, is the first to address the problem that Leo Strauss himself said was the theme of his studies - the theologico-political problem or the confrontation with the theological and the political alternative to philosophy as a way of life. In his theologico-political treatise, which comprises four parts and an appendix, Heinrich Meier clarifies the distinction between political theology and political philosophy and reappraises the unifying center of Strauss's philosophical enterprise. The book is the culmination of Meier's work on the theologico-political problem. It will interest anyone who seeks to understand both the problem caused by revelation for philosophy and the challenge posed by political-religious radicalism in current events. The appendix makes available for the first time two lectures by Strauss that are immediately relevant to the subject of this book and that will open the way for future research and debate on the legacy of Strauss.
