Aristotle on the Sources of the Ethical Life by Sylvia Berryman (review)

—Berryman’s goals in Aristotle on the Sources of the Ethical Life are threefold: to establish that Aristotle practiced what contemporary philosophers call metaethics; to refute the idea that Aristotle justified those ethics by recourse to human nature, understood as an “external point” for “establishing substantial ethical truths from a value-neutral perspective”; and to demonstrate that, for Aristotle, the source and justification for ethical demands is human practical reason.

Locating the source of normativity in practical reason does not mean that there are no “standards of truth other than human beings as a species.” Positioning Aristotle against both “Archimedean” naturalisms as well as relativisms and subjectivisms, Berryman sees Aristotle’s appeals to nature as delimiting “the kinds of normative positions that could guide practical reason,” and practical reason as responsive to biological constraints. Still, nature is no fulcrum. It does not mandate the contents of the life we should live. All of this together makes Berryman’s Aristotle a “constitutive constructivist,” which is to say, a nonskeptical, cognitivist nonfoundationalist.

Chapter 1’s “Introduction” sets the stage for the book’s metaethical project. Chapters 2 and 3 argue against two versions of the claim that “Aristotle was not reflective on the sources and justifications for his ethical views.” Chapter 2 places “Aristotle in the Ethics Wars” of the twentieth and twenty-first centuries, challenging the historicist view that “the kind of metaethical reflection about the sources of normativity” that preoccupies modern philosophy in response to “‘disenchantment’ of the modern world picture” would not have been available to Aristotle. Chapter 3, “Nature and the Sources of Normativity,” positions itself against scholars who maintain that Aristotle was complacent about the values of his own society and/or “too philosophically naïve to even reflect on the sources and justifications of ethical claims.” Inhabiting Aristotle’s social and intellectual milieu, it shows how the epistemological questions, commitments to materialist-scientific worldviews, as well as challenges to divine authority posed by fifth-century sophists, Plato, and fourth-century hedonists meant that “a philosopher in Aristotle’s position could hardly avoid being reflective on questions of the status of ethics.”

After establishing in chapter 3 that Aristotle could have grounded ethical claims in his natural philosophy, chapters 4 through 6 make the case that he did not. Exploring the philosophical work done by Aristotle’s appeals to nature, chapter 4, “Is Aristotle an Archimedean Naturalist?”, focuses on the apparent directionality of human development as well as references to “natural justice” and “natural virtue” in Aristotle’s ethical writings, while chapter 5, “Naturalism in Aristotle’s Politics,” scrutinizes the “naturalness of the polis” and “natural slavery” in Politics 1. Finding “only very minimal appeal to human nature” in the ethical treatises, Berryman sees Aristotle’s recourse to nature in Politics 1 as “the main anomaly” for which her refutation of Archimedean naturalism must account. Based on internal evidence in the Politics and comparison with Aristotle’s biological writings, Berryman concludes that Aristotle wrote the Politics before he “developed his more detailed biological theories.” Rather than evidence of naturalism, Aristotle’s appeals to nature in Politics 1, Berryman argues, are an early reflection of the “nomos-phusis distinction found in sophistic controversies” and a “kind of rhetorical move” based on thorough “prejudice and not reasoned inference.” Concluding “The Case Against a Naturalist Reading,” chapter 6 sets the stage for Berryman’s resourcing of Aristotle’s metaethics away from nature by exploring the inadequacies of the instrumental and theoretical rule-guiding reasoning implicit in naturalist accounts of Aristotelian practical reason.

Chapters 7 and 8 offer the book’s positive account. After elaborating Aristotle’s rejection of “metaphysical abstractions” as action-guiding, chapter 7, “Aristotle’s Metaethics,” recovers from the Eudemian Ethics human agency as the source of normativity in Aristotle. Action “carries with it an implicit commitment to the norms of practical reasoning,” and “Aristotle’s insight,” Berryman writes, “is the metaethical recognition that the practical...
