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)

The work of Dionysius of Halicarnassus has been traditionally divided into two parts: first, treaties of rhetoric and, secondly, Roman Antiquities, the history of Rome from its origins to the First Punic War. However, there is a common element among the rhetorical and historical writings that gives internal coherence to the whole work. This element is imitation, wich Dionysius used to link ethics and aesthetics at the service of building the tradition of the Roman people.

The relationship between William James and the stoics remains an enigma. He was clearly influenced by reading Marcus Aurelius and Epictetus throughout his career. Some work has been done on the thematic convergences between Jamesian pragmatism and stoic thought, but this study takes a different path. I argue that the rhetorical style that James uses in arguing for his moral claims in front of popular audiences can be better understood if we see it in light of the stoic style of (...) argumentation. I look at a text James read closely and recommended to close acquaintances—Marcus Aurelius's Meditations—to extract a sense of stoic rhetorical style. James's use of the stoic's tactics of vivid examples and rhetorical questions to shape the rhetorical experience of his audience and to thereby make his points becomes understandable as a possible extension of the stoic style of persuasion.

Sobre la risa puede hablarse de muchas maneras; cabe, por ejemplo, una aproximación fisiológica, otra psicológica o una tercera sociológica, que los antiguos no desatendieron por completo, si bien Cicerón prefirió investigar sus posibilidades retóricas. A nadie se le oculta la relevancia de chanzas y chistes para disponer a la audiencia de manera favorable o para ridiculizar al adversario; tampoco que esta estrategia, a despecho de su efectividad y por la misma, puede sobrepasar los límites de lo aceptable o de (...) lo provechoso. Cuestión tanto más grave cuanto que el orador puede y debe reírse de asuntos que, considerados en sí mismos, carecen de gracia. La retórica ciceroniana de la risa plantea y desemboca en una ética y una táctica del humor atenta al estudio y posible codificación de los principios rectores de tan poderoso recurso, que debe utilizarse de manera conveniente, adecuada y decorosa, lo cual presupone que no siempre es así y, por lo que interesa en estas páginas, que hay risas indebidas, próximas al vituperio, que pueden acarrear dificultades a quien las provoca, pues siempre es peligroso reírse de los poderosos. Cicerón, sin duda, era un individuo que insultaba mucho, con ingenio, gracia y en ocasiones con extraordinaria agresividad. (shrink)

ABSTRACT This article develops a theory of rhetorical impression through a critical genealogy of the term phantasia. The genealogy demonstrates cause for understanding phantasia as impression, not image. I trace phantasia as impression through the work of Plato and Aristotle but ultimately argue that the stoics offer the most productive leads for thinking through impressions, materiality, and sensations together. Specifically, I demonstrate how the stoics' concept of lekton can productively mediate the relationship between rhetoric, materiality, imagination, and idealism. In the (...) closing section, I suggest how a theory of rhetorical impression can address lacunae in existing new materialist approaches. (shrink)
