The first major piece of unpublished work by Leo Strauss to appear in more than thirty years, this volume offers the public the unprecedented experience of encountering this renowned scholar as his students did. Given as a course in autumn 1959 under the title "Plato's Political Philosophy," these provocative lectures—until now, never published, but instead passed down from one generation of students to the next—show Strauss at his subtle and insightful best.
