Book excerpt: Scholarship on the moral and political philosophy of the ‘School of Salamanca’ has either long been emphasizing the discontinuity between medieval and modern philosophy and the way this discontinuity is represented in the works of these authors or discussing issues of moral justification that are often seen as the heart of early modern practical philosophy. This volume offers a fresh perspective by focusing on the concept of law. This allows for an in-depth analysis of a variety of normative issues in the authors’ moral and political thought. It also suggest a more continuous picture of the transition from medieval to modern philosophy and proposes a more nuanced view of the importance of political concepts in the authors’s practical philosophy.
