"This book is a substantial achievement . I unhesitatingly recommend it to anyone interested in reasons, well-being or rationality." -- Luke Elson, Analysis "The book is a showcase of first-rate value theory in the analytic tradition, tightly situated in debates about the nature of well-being and the nature of normative reasons, with a few forays into moral theory and moral psychology." -- Owen C. King, Utilitas "Sobel's book is an extremely fair and subtle examination of subjectivism as well as of some arguments against subjectivism such as Parfit's and Scanlon's critiques. All essays in this collection - two of them are co-authored by David Copp - are very clearly written, contain lots of well-grounded arguments and are therefore of greatest interest for those who tend to think that subjectivism is true as well as for those who tend to think that this account is wrong."--Tobias Gutmann, Ethical Theory and Moral Practice "Sobel's essays in this book are some of the finest ever written in moral philosophy. Whatever one's favoured theory of value, I hope we can all agree that this book is an invaluable resource.
