"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 Kojeve) "On Tyranny is a complex and stimulating book with its 'parallel dialogue' made all the more striking since both participants take such unusual, highly provocative positions and so force readers to face substantial problems in what are often wholly unfamillar, even shocking ways." (Robert Pippin, History and Theory)"
