Abstract

This dissertation studies how Aristotle understands and justifies his Rhetorical Art. It proceeds by explicating the Art in its intellectual context. Rhetoric emerges as a dynamic investigation of human affairs working through the "given" in speech and thought to a plausible account, while giving consideration to the opinions and characters of both speaker and audience within the horizon of a particular occasion. The basic dynamic determines a structure which is comparable to Socrates' requirements in the Phaedrus. That this is the structure and dynamic is supported by considering the fundamentally contingent nature of human experience, understanding the inference types , common sense principles and starting points by which such experience is explicated, and placing such experience in three mutually exclusive genres. Aristotle's art is essentially the resulting plausible account while actual composition is supplementary. ;Aristotle limits the art by reference to dialectic and ethical life. When it is seen that Aristotle's Organon is not a science of logic and the Posterior Analytics is a rarely applicable mode of presentation, the point of dialectic becomes accessible. It too involves strenuous grappling with speech and thought, but its highest purpose lies in peirastic. Peirastic and sophistry are uses of dialectic which have a contrasting moral color. Peirastic aims at the discovery of ignorance and, at the same time, the difference between accident and essence and knowledge and opinion: Being educated is essentially knowing what one does not know. ;What Socrates only alludes to as political art, Aristotle attempts to expound as praxis perfected into phronesis. Even Aristotle does no more than suggest the nature of phronesis negatively as simultaneously a seeking, a finding and an act which is both self-determination and self-knowledge, and none of these separately; it is profoundly disruptive of existing opinion and most clearly to be seen in the rejection of the laws and rules upon which, as deliberation, it is dependent. The Art differs from Gorgias' rhetoric in its emphasis on the plausible and in its subordination to an ethical self-determination that gains the weight of experience appropriated by intelligence and virtue.
