The Roots of Normativity concerns one of the most basic philosophical questions: how to explain normativity in its many guises. Over many decades, Joseph Raz has sought to develop an answer to this question, according to which understanding normativity is understanding the roles and structures of normative reasons which, when they are reasons for action, are based on values. This volume collects twelve chapters which succinctly lay out his view, and determine its contours through some of its applications. The chapters also aim to clarify the ways in which normative reasons are made for rational beings like us. Raz’s value-based account of normativity is brought to bear on many aspects of the lives of rational beings and their agency, and in particular, their ability to form and maintain relationships, and to live their lives as social beings with a sense of their identity.
