Oxford Studies in Normative Ethics Volume 13 [PDF ebook] 

Oxford Studies in Normative Ethics is an annual forum for new work in normative ethical theory. Leading philosophers present original contributions to our understanding of a wide range of moral issues and positions, from analysis of competing approaches to normative ethics (including moral realism, constructivism, and expressivism) to questions of how we should act and live well. OSNE is an essential resource for scholars and students working in moral philosophy.
