4 - Divisions of speech

Summary

Rhetoric is, above all, a system which offers the prospect of organizing and classifying the apparently limitless variety of human speech. In turn, there are different ways in which one can understand the system of rhetoric, and other chapters in this Companion approach the issue through the different categories of speech that are established or the processes by which rhetoric takes shape in the writings of different theorists. The concern in this chapter is with the divisions within rhetoric itself, which are used to structure both its theoretical treatments and its educational practices: it offers an overview of rhetoric as a system, a dazzling, and at times baffling, elaboration of the process of public speaking developed over centuries.

The level of detail involved in treating structures comprehensively offers great scope for individual writers on rhetoric to create their own distinctive approach and, in consequence, their appeal as teachers, by choosing which areas to emphasize and elaborate upon. Moreover, the level of elaboration varies from one area of rhetoric to another; by concentrating on areas of particular contestation, we can see how the increasing subdivision of rhetorical theory marks out areas of authority and anxiety in the practice of oratory.
