Supervisory Committee THE CITY UNIVERSITY OF NEW YORK iii Abstract NATURE’S GOODNESS: AN ARISTOTELIAN ACCOUNT By Nathan Metzger Adviser: Peter Simpson Neo-Aristotelians have made major headway in moral theory, and it is now commonplace to find philosophers defending the reality of goodness through a teleological analysis of human being. Whatever the merits of this approach, it has suffered from a lack of a sustained defense of its pre-modern metaphysical panorama: the Aristotelian conception of the human good gets traction only if its decidedly pre-modern and ‘robust’ philosophy of nature is defensible in its own right. In this dissertation, I aim to give a partial breakdown of the particular sort of metaphysical project that the Aristotelian moral theorist assumes, but does not always explicate. In particular, I aim to show how neo- Aristotelians rely on a particular view of substance that, while certainly challenging contemporary naturalist construals of the same, is nevertheless defensible in its own right. Moreover, it might well be the case that even ‘liberal’ contemporary naturalist construals of ‘moral facts’ face difficulties that cannot be overcome; for they might only be able to countenance the less deflationary moral ontologies they desire by first assuming a view of substance that puts pressure on the entirety of the ‘modern’ project. The first part of this dissertation will focus on the ways that an Aristotelian nature is defensible. The second part will show in more detail how this pre-modern vision of reality helps to locate and in some cases even ‘solve’ certain metaethical conundrums. The goal is to show why iv an Aristotelian moral theory can offer a credible alternative to the usual ‘moral realist’ positions in contemporary metaethics, by offering not just a more plausible view of human goodness, but a more plausible view of nature as a whole. v Acknowledgements This modest work represents the end-result of a philosophical conversion. I wouldn’t have put my name to any of these ideas at the start of my graduate career—back when I knew a thing or two. I am grateful to Peter Simpson, not just for his own work, which played a part in my change of views, but also for our many conversations over the course of my graduate tenure, and for his help with this project. He patiently put up with many inchoate attempts at making my new-found point, he dogged me to be clearer and more charitable, and he pressed me to investigate my own arguments and their implications more deeply. I couldn’t have asked for a better advisor. I’m also grateful to my two readers, Douglas Lackey and Jesse Prinz, for their generous, kind, and challenging comments on these pages. Like any student, my ideas evolved through many ‘spirited’ conversations with professors, friends, and colleagues. I need to especially thank my two dear pals Tim Czech and Kevin Byrne, with whom I spent countless hours talking, arguing, and philosophizing. They witnessed first-hand my slow evolution in world-view, and were extraordinarily patient through it all. I’m also blessed to have supportive parents, who didn’t flinch when I told them that I was going to move to New York to try out philosophy for a living. Lastly and most importantly, I must thank my wife, Elizabeth. I don’t know where I’d be without her angelic patience and extraordinary help. If I were to begin to delve into the ways that I’ve leaned on her during these years, I’d have another book on my hands. I’d like to dedicate these pages to our three boys—Peter, John, and Charlie. vi Table of Contents Chapter 1 1 Preliminary Reasons for Accepting Substantial Form 1.1. Introduction 1 1.2.

The argument is based on the Aristotelian idea that facts about human value reduce to natural facts, because it endorses the Aristotelian idea of substantial form: we can rightly speak of natural goodness because nature is inherently normative. The greatest obstacle to this conception of value realism comes from the contemporary naturalist’s insistence that formal and final cause—that is, the ways in which a substantial form has both an essence and an aim--are remnants of a philosophy of nature that have been falsified by modern science. Therefore, the bulk of this thesis will try to show why these naturalist arguments can be overcome. This must done, not only because the naturalist’s criticism of the Aristotelian philosophy of nature—the very philosophy that grounds this moral theory--is impressive, but also because some of the most prominent defenders of the Aristotelian metaethical account, like Philippa Foot’s (cf. 2003), do not address these impressive naturalist arguments at any length.1 Indeed, 1 Certainly, there are impressive modern defenses of Aristotelian or quasi-Aristotelian notions of substance (cf.
