In Chapters I-III, I argue that Nietzsche is a critic of "morality" in the sense of any system of values that has one or both of the following features: it presupposes the truth of certain descriptive claims about human agency, in the sense that for the evaluative categories to be intelligibly applied to persons these claims must be true ; it favors the interests of the "lowest" at the expense of the "highest" men, the embodiments of human excellence. I illustrate, in particular, how this latter component of "morality" informs the attack on all Nietzsche's seemingly disparate targets : in each case, Nietzsche shows that such norms are inhospitable to the realization of human excellence. Nietzsche's critique is distinguished from recent critical work in analytic ethics : the former is concerned with the real effects of morality on the cultural conditions necessary for the flourishing of human greatness, while the latter writers are only concerned with the inability of philosophical theories of morality to find conceptual space for our various mundane personal projects. ;Chapters IV-VI address the metaethical question implicit in Nietzsche's "revaluation of values": what is the status of the values Nietzsche relies on in criticizing morality? I argue that: Nietzsche is a type of realist about judgments of prudential value ; and Nietzsche is an anti-realist about judgments of non-prudential value . In considering Nietzsche's arguments for , particular attention is accorded the neglected influence of the German materialism of the 1850s and 60s. I argue that Nietzsche embraces a "naturalistic" conception of persons , which leads him to think that judgments of non-prudential value can be "explained away" in terms of psychological and physiological facts about persons
