    • Kagan, Shelly. The Geometry of Desert 

      Skow, Bradford (University of Chicago Press, 2014-01)
      Other things being equal, people ought to get what they deserve. If there is such a thing as common sense, this claim is part of it. But life is complicated, and this claim does not get us very far. Suppose I could give A ...
