This article explores how law and economics is viewed from the perspective of moral philosophy. Given that ‘law and economics’ is a category that covers a large and diverse set of theories and theorists, and that ‘moral philosophy’ as a category is even larger and more diverse, there are a vast number of potential topics and perspectives. The article offers a sample of the many intersections of those two categories. Part I offers a brief introduction to some central ideas of economics and to the different schools of moral philosophy. Part II summarizes some defences of law and economics from the perspective of moral philosophy, while Part III summarizes criticisms from the same source.
