According to Ronald Dworkin, all judges are by necessity philosophers, and no judge is a better philosopher than Hercules. This superhuman jurist understands that law's empire embraces not just decisions about rights made in the past, but also rights implicit in the theory of political morality that those decisions presuppose. He is able to survey all of the diverse laws within a system and then construct a comprehensive theory of political morality that shows those laws to be as coherent and unified and just as they can be. From this theory not only will right answers in hard cases emerge, but the value of integrity-the value of extending to everyone the rights extended to some so that equal concern and respect is secured for all-will be honoured. In contrast, Herbert, the judge Dworkin introduces as Hercules' nemesis, thinks that law ends just at the point where hard cases begin. Herbert is intellectually flatfooted in the face of legal challenges that Hercules can handle adeptly and accurately.
