The book is sparklingly clear and contains abundant insights and interesting arguments...a rich and rewarding book which will contribute greatly to a number of debates throughout moral philosophy.
Guy Fletcher, Ratio
Crisp advances substantial theses about reasons, welfare, pleasure, moral knowledge, intuition, moral disagreement, personal identity, impartiality, population axiology, and more...this bold and sweeping work contains quite a number of provocative discussions of interest to theoretical ethicists of many stripes.
Chris Heathwood, Notre Dame Philosophical Reviews
Because the book covers such a range of issues in such a short and well-integrated way, reading it will be illuminating for many...I can see ample reason for a moral philosopher to read this book: for its stimulation and sweep, and to wake one from one's dogmatic slumbers. Nod off for a second here, and you will miss crucial arguments entirely.
Henry S. Richardson, Mind
Roger Crisp belongs in the company of Derek Parfit and Peter Singer as one of the most distinguished contemporary philosophical defenders of the legacy of Henry Sidgwick...This is an excellent work - clear, concise, and compelling. And it packs a powerful philosophical punch.
Bart Schultz, Ethics
