Richard Epstein is one of the most prolific, and eloquent, scholars of the “Chicago School” approach to law and economics. . . . An argument over whether one or another scholar is correct about an interpretation of a legal treatise from 1964 is not very exciting. But that is just the origin story. As one might expect from a scholar of Epstein’s stature and ferocity, the book that resulted is a much more general, more interesting, and frankly more important set of insights.
