"Darwall sets a new standard for discussion... [He] is notably clear and noble about the sources of his claims, and he has an immensely illuminative way with the history of ethics."--A.E. Wengraf, Philosophical Inquiry "Anyone who cares for ethics and conceptual analysis has good reasons to engage with the close reasoning in this book."--Richard J. Arneson, Ethics "I warmly recommend the book. Darwall's prose is as elegant and captivating as ever, and anyone with an interest in welfare, metaethics, or moral psychology will find useful things."--Jonas Olson, Economics and Philosophy
