Law's Empire
Dworkin begins with the question that is at the heart of the whole legal system: in difficult cases how do (and how should) judges decide what the law is? He shows that judges must decide hard cases by interpreting rather than simply applying past legal decisions, and he produces a general theory of what interpretation is—in literature as well as in law—and of when one interpretation is better than others. Every legal interpretation reflects an underlying theory about the general character of law: Dworkin assesses three such theories.
