ACKNOWLEDGMENTS

I wish to express my gratitude to the John M. Olin Center for Inquiry into the Theory and Practice of Democracy, the LeFrak Forum, and the Symposium on Science, Reason, and Modern Democracy, and to Nathan Tarcov and Richard Zinman, conference organizers, for the invitation to participate in the conferences at the University of Chicago and Michigan State University on Leo Strauss’s Natural Right and History in April–May 2001, which were the occasion for a lecture that became chapter 7. Also I express my debt to Alfred Denker and Holger Zaborowski of the Heidegger-Forschungsgruppe for the opportunities to speak at the 2004, 2006, and 2008 meetings of the Forschungsgruppe in Messkirch, Germany, out of which arose chapters 5 and 6, and to the late Dr. Kurt Pritzl, O. P., dean of the School of Philosophy at the Catholic University of America, for his invitation to give a paper in the Fall 2007 Lecture Series on Pre-Socratic Philosophy, from which my first chapter is derived. My thanks go to various friends and colleagues with whom I have discussed parts of the book: Avner Ash, Fred Baumann, Diego Benardete, Robert Berman, Ronna Burger, Michael Davis, Patrick Goodin, Victor Gourevitch, Richard Hassing, Mark Lilla, Nalin Ranasinghe, Susan Shell, Martin Sitte, Nathan Tarcov, Holger Zaborowski, and Catherine Zuckert. To David Brent and Laura Avey at the University of Chicago Press and Brian Walters I am greatly indebted for help and support with the manuscript, technical and otherwise. It has been a great pleasure to work with Susan Tarcov in the final stage of editing.
