Reviewed by: Metanoia: Rhetoric, Authenticity, and the Transformation of the Self by Adam Ellwanger Ryan McDermott (bio) Adam Ellwanger, Metanoia: Rhetoric, Authenticity, and the Transformation of the Self, University Park, PA: The Pennsylvania State University Press. 2020. 202 pp. ISBN: 978-0-271-08593-7. This book moves metanoia and related concepts of transformation and conversion to the center of our theoretical understanding of ethos. Whereas for Aristotle ethos had depended on the audience—did they consider the speaker trustworthy?—now the speaking subject determines how ethos ought to be recognized, and the audience must defer to the subject's self-understanding. As a rhetorical device, Ellwanger shows, metanoia is one of the most important means by which subjects can establish ethos in either of these models. This book's consistent concern is to analyze how, precisely, metanoia is employed in the service of ethos in various contexts and rhetorical and ethical models. At its best, Ellwanger's study adopts a comparative method—what he calls "paratactical rhetorical analysis"—that allows different understandings of metanoia to clarify each other by contrast. Ellwanger also approaches his topic diachronically, telling a story of development or transformation in the practices of metanoia. This narrative gives the book its structure, moving from classical and ancient Jewish sources to early Christianity, then the Protestant Reformation, post-Enlightenment modernity, and what Ellwanger characterizes as the postmodernity of today. Each chapter's narrative section culminates with a theoretical elaboration, which is then worked out in a section of comparative examples. This reviewer found the heuristic, second section of each chapter the more effective. For example, Chapter One compares five different Christian conversion stories (all post-1850), including the Sioux Indian Ohiyesa's memoirs of his transition From the Deep Woods to Civilization, two accounts of conversions in China, and two testimonies from members of the rock band Korn. Ellwanger is able to compare these diverse experiences with impressive conceptual clarity. The major conceptual contrast that runs throughout the book is that between metanoia and epistrophe. When speaking of the contrast, Ellwanger characterizes epistrophe as a 360-degree conversion, a return home. He reserves metanoia for 180-degree conversions, which renounce the past self and result in a rebirth, a replacement of the original subject by a "completely" new subject. In Ellwanger's account, all Christian metanoia "is a substitutive transplanting of identity," and it "locates the substitution at the core of one's being" (95). Modern, secular conversions can also involve renunciation of a previous self, but they lean more heavily on epistrophic unveiling of and return to the original, authentic self. Epistrophic conversion never renounces the real self, but rather the former illusion of self. Theoretically, this contrast harbors considerable explanatory power. It helps make sense of why ethos can reside alternately in audience or speaker. When a speaker seeks to establish ethos by claiming that her previous self is dead and she is now a new (and better) self, she might appeal to the audience to authenticate whether she is indeed new and better. But when a speaker [End Page 93] claims to have discovered and returned to her original, authentic self, she expects the audience to acknowledge her authority to authenticate herself. The contrast between ethoi established by metanoic or epistrophic conversion narratives plays out in fascinating ways in the contrast between Bruce Jenner's coming out as gender-transitioned Caitlyn Jenner and Rachel Dolezol's racial transition from identifying as a White woman to identifying as a Black woman. In public responses to each narrative (which unfolded roughly contemporaneously), Ellwanger identifies both metanoic and epistrophic discourses. Each kind was employed by both critics and defenders of the respective claims to identity. The conflict between metanoic and epistrophic understandings of identity transition help account for the intense scrutiny and controversy each story attracted. The weakest part of the book is its narrative of secularization, which frames Christian and modern models of conversion as mutually exclusive. Ellwanger asserts that "in Judeo-Christian thinking metanoia and epistrophe were two fundamentally opposed models of conversion" (100). By contrast, "the definitive feature of modern transformation is a reconciliation of" the two models (p. 143). Likewise, "Christianity is especially...
