This Handbook maps a central terrain of philosophy, and provides the definitive guide to it. An illustrious team of philosophers explore the concept of a reason to do or believe something, in order to determine what these reasons are and how they work. And they investigate the nature of 'normative' claims about what we ought to do or believe.
