[T]he emphasis on the normative dimensions of speech and its consequences for metaethics are highly interesting and deserve closer investigation. Cuneo's book is a fine start.
John Eriksson, Ethic
this is a superb book, original and highly rigorous, and one that rewards repeated reading.
James Edwin Mahon, Notre Dame Philosophical Reviews
Positive arguments in favor of moral realism are not wildly abundant. Cuneo has provided us with one that is bold, highly original, clearly argued, broad in its sweep and rich in detail. His book is compulsory reading for anyone interested in the nature of moral truth.
