An inquiry into the rhetorical aspects of history may seem paradoxical, given that historical discourse is not typically included among those types which, since Aristotle, have been understood to be governed by rhetoric; these types being the deliberative council, the tribunal and the commemorative assembly. It was to these specific audiences that the three kinds of discourse—the deliberative, judiciary, and panegyric—were addressed. However, are the boundaries of the historian's audience sufficiently delineated in order to allow us to identify it as a specific addressee? This first objection, which regards the very legitimacy of the subject of these remarks, can be met by noting a common trait that links history to the above-mentioned three types of discourse; that is, competition between opposed discourses requiring a choice. In each case the aim is to structure a debate that calls for a clear-cut decision. Yet a major problem of the discipline of history is that it allows both for widely varying descriptions of the same series of events, and sanctions the use of a variety of equally acceptable rules or preferences for interpreting a given slice of the past.
