On Tyranny is Leo Strauss's classic reading of Xenophon's dialogue Hiero , or Tyrannicus , in which the tyrant Hiero and the poet Simonides discuss the advantages and disadvantages of exercising tyranny. Included are a translation of the dialogue from its original Greek, a critique of Strauss's commentary by the French philosopher Alexandre Kojève, and the complete correspondence between the two. This revised and expanded edition introduces important corrections throughout and expands Strauss's restatement of his position in light of Kojève's commentary to bring it into conformity with the text as it was originally published in France. "Through Strauss's interpretation, Xenophon appears to us as no longer the somewhat dull and flat author we know, but as a brilliant and subtle writer, an original and profound thinker. What is more, in interpreting this forgotten dialogue, Strauss lays bare great moral and political problems that are still ours."-Alexandre Kojève.
