This essay argues that Aristotle's categories of oratory are not as useful in judging the methods of Sophistical rhetoric as his presentation of time. The Sophistical argumentative method of “making the weaker the stronger case” is re-evaluated as a political practice. After showing this argument's relation to power and ideology, Aristotle's philosophy, which privileges a procedure of argument consistent with the politics of a polis-ideal rhetoric, is offered as reason for objecting to Sophistical rhetoric. The essay concludes that Sophistical rhetoric (...) prefers the concept of possibility over Aristotelian actuality, and offers a need for an ideological space of radical, generative possibility in rhetorical theory.

The Helen of Gorgias is designed to provoke the aspiring speaker to consider his relationship with society as a whole. The speech's extreme claims regarding the power of logos reflect simplistic ideas about speaker-audience relations current among Gorgias' target audience, ideas reflected in an interpretive stance towards model speeches that privileges method over truth. The Helen pretends to encourage this conception of logos and interpretive stance in order to expose the intense desire and naïve credulity that drive a coolly technical (...) appraisal of model speeches. The Helen thus manifests, with a playfulness suited to its liminal position, a concern for the ethical and social formation of those who might accept the invitation to study logos. (shrink)

The term dunamis, by which Aristotle defines rhetoric in the first chapter of The Art of Rhetoric, is a "power" term, as its various meanings in Aristotle's corpus—from vernacular ones like "political influence" to strictly philosophical ones like "potentiality"—attest.1 In the Rhetoric, however, dunamis is usually translated as "ability" or "faculty," a designation that, compared to other terms that describe persuasion in ancient Greek poetics and rhetoric (such as "bia" ["force"] or "eros" ["seduction"]), marks rhetoric as a neutral human capacity (...) rather than the use of language entangled in the vagaries of violence and desire.2 John Kirby calls Aristotle's definition "one of the boldest moves in the history of ..

This dissertation explores how antiquity and some of its early modern admirers understand the notion of certainty, especially as it is theorized in Quintilian's Institutio Oratoria, a first-century educational manual for the aspiring orator that defines certainty in terms of consensus. As part of a larger discussion of argumentative strategies, Quintilian turns to the “nature of all arguments,” which he defines as “reasoning which lends credence to what is doubtful by means of what is certain” (ratio per ea quae certa (...) sunt fidem dubiis adferens: quae natura est omnium argumentorum, V.10.8). These certainties, he later specifies, include not matters of scientific demonstration or objective fact, but the agreements of various communities: the laws of cities, local customs, and other forms of consensus. As the foundation of persuasive rhetoric, these consensus-based certainties situate argumentation as the practice of crafting agreements rather than demonstrating necessary conclusions. Taking as its point of departure Quintilian's novel understanding of certainty, this study looks to some of Quintilian's intellectual forebears as well as his later readers to show how his work is both a nexus of earlier intellectual developments as well as an important inspiration for later accounts of certainty, even into the early modern period. After illustrating in the first chapters of this dissertation how Quintilian's manual incorporates elements from Aristotelian notions of dialectic and rhetoric as well as from Ciceronian skeptical approaches to epistemology, I show how Quintilian's curriculum for the orator shapes the thought of Italian humanists, especially that of Lorenzo Valla (1406–1457), a reformer of scholastic logic and dialectic, and Giambattista Vico (1668–1744), an influential Neapolitan jurist. Adopting Quintilian's rendering of certainty as a matter of agreements and conventions, these later authors elaborate their own novel approaches to various fields—including law, language, and logic—through this ancient understanding of certum. Contrary to modern notions of certainty as objective or scientific fact, Quintilian's humanist readers continue to root this concept in consensus, both within the courtroom and without. (shrink)
