Kant’s Philosophy of Communication provides a valuable and thought-provoking reassessment of Kant’s place in the rhetorical tradition. Complementing recent work by Scott Stroud, Pat Gehrke, and others who have essayed an expanded role for rhetoric in Kant’s critical works, Ercolini focuses on texts at the edges of the Kantian canon to produce an account of an “‘other’ Kant” (7) who provides a counter-narrative to caricatures of enlightenment thought as being dismissive of rhetoric (220). Ercolini frames Kant’s enlightenment as a practice: a process of embodied, collective knowledge production and critique with a robust role for rhetoric, communication, and social exchange (220). In addition to contributing to rhetorical studies of Kant, this account of Kant as an explorer of the social, embodied, and affective dimensions of thought takes a place beside the work of twentieth- and twenty-first-century philosophers, from Gilles Deleuze and Michel Foucault to Jean-François Lyotard and Jürgen Habermas, who have explored Kant’s continued relevance for contemporary philosophical and political concerns.The first two chapters of Ercolini’s book address Kant’s relationship to rhetoric in conversation with existing rhetorical scholarship on Kant. Ercolini sums up rhetorical engagement with Kant’s most direct discussions of rhetoric, arguing that, while Kant disparages a narrow vision of oratorical practice, his work accords a wide role to “communication, reasoned public discourse, deliberation, critique and other elements” (6) of the broad intellectual projects associated with contemporary rhetorical studies. These chapters also push back against the austere image of Kant’s life that modern philosophy has inherited, discussing Kant’s interest in billiards and gambling, the vibrancy of his lectures, and his lively social milieu (7–8), all of which attest to an interest in discussion and public engagement. Ercolini’s observations in these chapters complicate Kant’s attitude toward rhetoric rather than establishing him as its champion, but this approach is an asset: Kant is set on philosophical common ground with rhetoric without underplaying the tensions and complexity found in his thought.In an elegant compositional gesture, the following chapters mirror each major aspect of Kant’s critical philosophy, treating the metaphysical, ethical, and aesthetic facets of the “other” Kant. In Chapter 2, Ercolini examines the tepid response that initially greeted the Critique of Pure Reason, focusing on Kant’s reply to a critical review by Christian Garve that set much of the tone for the Critique’s initial reception. Working through Kant’s exchanges with Garve, as well as the polemic against Garve’s review in the Appendix to the Prolegomena to any Future Metaphysics, Ercolini argues that the failure of other philosophers to effectively popularize the insights of the first Critique prompted Kant to reflect on the need for popular philosophical work. Kant distinguishes “alleged popularity’” (78) that renders philosophical insight in buzzwords and slogans without intellectual rigor from true popularity: writing that places critical philosophy in conversation with public concerns in order to prompt collective debate and advance the task of thought beyond the musings of the lone philosopher (64). In this sense, “the monument of Western intellectual history known as the first Critique actually serves as a propaedeutic to the Prolegomena” (66) and its popular articulation of critical philosophy.In its inversion of the status of Kant’s Critiques relative to his more avowedly popular philosophy, Chapter 2 serves as the fulcrum of the book’s argument, providing a clear rationale for the ethical and aesthetic discussions in the rest of Ercolini’s book. Chapter 3 extends the idea of popularity to develop an “embodied ethics” (91) out of Kant’s anthropological texts and the Groundwork of the Metaphysics of Morals, arguing that even as Kant insists on the purity of the categorical imperative, he cannot escape the impurity of empirical examples and the ethical vertigo they create. Kant’s anthropological texts offer a parallel ethics focused on the “dynamic between discipline and enjoyment” (129) that characterizes sociability and conversation in public, and emphasize the body and its pleasures, offering insights for communication ethics centered on alterity and the care of the self.Chapters 4 and 5 mirror the later critical philosophy’s discussion of aesthetic judgment. Chapter 4 introduces the Critique of Judgment’s key concepts, and frames Kant’s turn to aesthetics as both a primary site of concern about rhetoric and an account that, rather than dismissing rhetoric, “infuses [it] with a capacity and power that certainly deserves attention and respect,” even if it remains a worry for Kant (163). Chapter 5 engages Kant’s writings on tone and style. Ercolini argues that Kant’s explicit reflections on style provide a set of strategies for effective popular scholarship, as well as a guide to ethical rhetoric that emphasizes liveliness, perspicuity, a balance between logical and aesthetic perfection, and a style that is “communicable and intelligible to all who have functioning faculties in common” (174). Chapter 5 concludes with a consideration of tone, Kant’s term for the affective dimension of language. Beyond augmenting the observations about style from earlier in the chapter, the discussion of tone affirms that style and rhetoric for Kant are more than merely ornamental: they affectively dispose the listener in accordance with a given message (190). While more work remains to expand this connection, Ercolini’s discussion of tone sets up the basics of a materialist theory of rhetorical style that merits future expansion.Beyond the contributions it makes to rhetorical studies of Kant, Ercolini’s book is important to scholars of rhetorical history for the way it brings the world of eighteenth-century German philosophy to life. The book places many of Kant’s occasional essays in context as engagements in the public debates of Kant’s time (201), and uses that context to make a powerful case for those essays’ significance as public scholarship. Ercolini also fleshes out Kant’s role in the German enlightenment, particularly with respect to rhetoric’s place in the academic system in which Kant taught (48–57), and deftly treats Kant’s debates with other scholars and his participation in Königsberg’s social circles. These discussions generate the book’s most significant claims about the history of rhetoric—against the thesis that the enlightenment heralded a denigration of rhetoric, Ercolini argues that scholars need only look in the right places to find evidence of a vibrant rhetorical culture of which Kant was a part.Kant’s Philosophy of Communication is an enjoyable read that will provide substantial food for thought to philosophers of communication, historians of rhetoric and philosophy, theorists of public scholarship, and anyone familiar with the basics of Kant’s critical philosophy. The primary place the book could do more (and its biggest opening for future work) is in the implications it outlines for rhetoric’s discussions of contemporary philosophy. Ercolini places her reading in conversation with a number of more contemporary uptakes of Kant’s work (14), and engages at length with Deleuze’s work on Kant (in Chapter 4) and Foucault’s essay on “What is Enlightenment?” (in the introduction and conclusion). These readings work well as written, but the short circuit they make between Kantian enlightenment and the concerns of contemporary materialist and poststructuralist theories of rhetoric remains to be explored. Moreover, some of the traveling companions Ercolini selects for Kant sit uneasily together—Foucault’s and Habermas’s versions of enlightenment would hardly agree, and while that tension is highlighted (212-–13), the implications of the “other” Kant for the relationship between these thinkers are not fully explored. If taken at their full value, Ercolini’s claims about Kant might productively trouble many of rhetoric’s narratives about modernity and its afterlives. Such troubling deserves to be further pursued, in this work or future projects.

In virtually every epoch of its history, the theory of rhetoric has been associated with large, anonymous groups of people. They appear sometimes as crowds and at other times as mobs. At still other times, these large, anonymous groups of people are figured as herds, (counter)publics, imagined communities, “the people,” the audience, or social imaginaries. In whatever guise they appear, these anonymous groups of people have played a major role in the development of the idea of rhetoric. A few examples will make my point. Plato (2001) defined rhetoric as discourse that would persuade an ignorant crowd (94). Augustine (2001) tailored rhetoric to the “multitude of the wise” (459). In the sixteenth century, Castiglione (2001) calibrated rhetoric to the tastes of “ladies or gentlemen” (663). In the eighteenth century, David Hume (2001) suggested that discourse must account for “man in general” (836). Thomas Sheridan (2001) developed his “Lectures on Elocution” from a consideration of “man in his animal state” (884). By 1828, Richard Whately (2001) could characterize the entire history of rhetoric as so many theories on how to persuade the “promiscuous multitude” (1007). In 1958, Chaim Perelman and Lucie Olbrechts-Tyteca made a large, anonymous group of people—the “universal audience”—famous as the enabling presupposition of all rational argument (Perelman and OlbrechtsTyteca 1991, 31–35). Finally, consider the vibrant subfield of public sphere theory. In the first decade of the twenty-first century, public sphere theory may be the most institutionally secured of rhetoric’s modalities. In this popular mode, rhetoric is understood as the democratic practice of engaging groups of people qua citizens. Administrators seem to love this vision of rhetoric. Basic courses in both writing and speech are often designed explicitly as training in civic engagement, and institutionalized centers for civic engagement are now a common feature of research universities. Rhetoric, we might say, has generated institutional security by tying its fate to (and betting its value on) a particularly resonant large group of anonymous people: the
