"John Hawthorne is widely and rightly regarded as one of the leading philosophers of our time, and in this book, he turns his formidable intelligence to ethics. Carefully considering ingenious hypothetical cases and drawing on a deep knowledge of other areas of philosophy, Hawthorne and his coauthors offer searching examinations of central topics in normative ethics. The result is a work that is at once challenging, illuminating, and engaging." --Thomas Kelly, author of Bias: A Philosophical Study "This is a terrific book, in which John Hawthorne's characteristic combination of verve, insight, and rigor is on full display. It probes, in great depth and detail, important aspects of commonsense morality, finding crucial distinctions that have been too often overlooked, intuitions whose sources have been misdiagnosed, hypotheses that have been motivated by a limited diet of cases, and troubling inconsistencies in our ordinary moral thinking." --Jacob Nebel, Princeton University "This great book is jam-packed with new insights and compelling arguments, with a striking combination of creativity and rigor throughout." --Brian Hedden, Massachusetts Institute of Technology.
