Book I, chapter 4
Aristotle now moves to the specifics of the orator in the political context. The political rhetorician does not concern himself with what does or does not exist, but with what may happen. Specifically, the rhetorician will give counsel about what happens deliberately as opposed to what happens naturally. There is no legislation which will stop natural events or accidents. Yet legislation can be used to deal with outcomes of such events. He identifies five matters of importance in political deliberation: “ways and means, war and peace, national defence, imports and exports, and legislation” (1359b). There are various subcategories of knowledge the rhetorician must have about those fields, categories detailed in brief by Aristotle.
