"But just how "sinister" was Leo Strauss himself? The answer depends on how a reader approaches his books. If you read Strauss with a well-disposed spirit, he can be interpreted as a genuine friend of American liberal democracy. He worked to create an elite that was strong, sober, and sufficiently free of illusions about the goodness of man to fight the totalitarian enemies of liberal democracy-be they fascists, communists, or Islamicist fundamentalists. But if you read Strauss with a skeptical mind, the way he himself read the great philosophers, a more disturbing picture takes shape. Strauss, by this view, emerges as a disguised Machiavelli, a cynical teacher who encouraged his followers to believe that their intellectual superiority entitles them to rule over the bulk of humanity by means of duplicity. The worst thing you can do to Leo Strauss, perhaps, is to read his books with Straussian eyes."
