On Tyranny remains a perennial favorite, possessing a timelessness that few philosophical or scholarly debates have ever achieved. On one hand, On Tyranny is the first book-length work in Leo Strauss's extended study of Xenophon, and his "Restatement" retains a vivacity and directness that is sometimes absent in his later works. On the other, "Tyranny and Wisdom" is perhaps the most succinct yet fullest articulation of Alexandre Koj©·ve's overall political thought, and it presents what may be the most uncompromising alternative to Strauss's position as a whole. This volume contains for the first time a comprehensive and critical examination of the debate from scholars well versed in the thought of Strauss, Koj©·ve, Hegel, Heidegger, and the end of history thesis. Of particular interest will be the appendix, which offers for the first time Koj©·ve's unabridged response to Strauss, a response previously available only from the Fonds Koj©·ve at Le Biblioth©·que Nationale de France. Accessible to students and scholars alike, this volume works equally well in the classroom and as a resource for more advanced research.
