WINNER OF THE AMERICAN PHILOSOPHICAL ASSOCIATION BOOK PRIZE (2015). Building Better Beings presents a new theory of moral responsibility. Beginning with a discussion of ordinary convictions about responsibility and free will and their implications for a philosophical theory, Manuel Vargas argues that no theory can do justice to all the things we want from a theory of free will and moral responsibility. He goes on to show how we can nevertheless justify our responsibility practices and provide a normatively and naturalistically adequate account of responsible agency, blame, and desert.
