Abstract

352 RHETORICA Jeanne Fahnestock, Rhetorical Figures in Science (New York: Oxford University Press, 1999), xiv + 234 pp. The title of this work well represents the focus of the book, but it fails to convey the breadth of content it contains. Jeanne Fahnestock's book displays a range of erudition not only in the history of science but in the history of rhetoric as well. Unlike other studies that have treated the use of metaphors and analogy in scientific literature, this one reveals the work of some little marked but ubiquitous figures of speech in many classic and modem texts in science. Fahnestock's aim, however, is not just to show the way in which these figures have influenced the turn of scientific thought, or have structured its expression, but she seeks to illuminate the nature of rhetorical figures themselves. The book claims that certain figures are actually condensed lines of argument and that they appear in all kinds of discourse. She selects for close study five figures of particular importance to scientific reasoning: antithesis, gradatio, incrementum, antimetabole, ploche, and poliptoton. These are looked at systematically, with historical accounts and illustrations of each, followed by well-developed examples of their use in a coherent topical, not chronological, order. Throughout the work Fahnestock has also included visual representations that bear witness to the structural figuration behind them. The first chapter of the book alone, "The Figures as Epitomes", should prove invaluable to historians and teachers of rhetoric and literature. Fahnestock first clarifies the confusing categories of tropes, schemes, figures of diction and thought. Next she examines leading theories of figuration: figures are departures from "normal" or "typical" word use; figures ornament or embellish, adding emotion, force, charm. Figures may do all of these things, she says, but essentially they are composites a "formal embodiment of certain ideational or persuasive functions" (p. 23). She defines them as "an identifiable convergence, felicity, or synergy of form and content" (p. 38). As such the most useful approach to the figures is to look at their function. Accordingly, she examines the function of the figures mentioned above to condense or epitomize lines of argument. The key to the figural epitome lies in the topics, Reviews 353 lines of argument best described in Aristotle's Topics and Rhetoric, which he identified as common ways of reasoning. In the second chapter on antithesis, a figure based on the topic of opposites, the author explores a variety of scientific examples, including Bacon's tables of absence and presence and Darwin's examination of emotion in man and animals. The figures of series incrementum and gradatio, described in the third chapter, she explains as products of the dialectical topic of property when considered from the standpoint of the more and the less and similarities. In the scientific illustrations for the chapter, the figures are shown to be constitutive of both thought and expression. The author suggests a continuity between the rhetorical series and mathematical series, illustrating this with Newton's discussion of motion and later theories in astronomy. The subject of chapter four, antimetabole, another figure which epitomizes arguments from property, displays repeated terms in two cola, the second of which reverses the grammatical and syntactic order of the first ("Ask not what your country can do for you, but what you can do for your country"). Although this figure has not been consistently stressed in stylistic discussions over the years, Fahnestock sees it as having given scientists an especially fertile tactic of conceptual reversal. Newton in mechanics, Farraday and Joseph Henry in electromagnetism, Lamarck and Lewontin in theories of evolution, all furnish examples of the figure's usefulness. The final chapter on ploche and poliptoton introduces figures of repetition, probably unfamiliar to most readers. Pioche, described as "perfect repetition", is a word woven into a discourse in the same, or at times, in a different, sense. The second figure, polyptoton, appearing in highly inflected languages more frequently than in English, repeats a word but does so in a different grammatical case. In a dazzling account of the history of writings on electricity, the author documents the grammatical shifts that occur as experimenters begin to understand its nature. First a...
