Joseph Raz's new book, Between Authority and Interpretation , collects his most important papers in the philosophy of law and the theory of practical rationality from the mid-1990s to the mid-2000s. In these papers, Raz not only advances earlier theses but also breaks new ground in a number of areas. I focus on three of Raz's topics here: theories of law, separability and necessity, and the normativity of law. While I am generally sympathetic to Raz's thinking on these topics, I raise some room for doubt - especially with regard to his pessimism about finding a uniquely best theory of law and the relationship between law and morality
