Der Nutzen von Rhetorik

“before some audiences not even the possession of the exactest knowledge will make it easy for what we say to produce conviction. For argument based on knowledge implies instruction, and there are people whom one cannot instruct. Here, then, we must use, as our modes of persuasion and argument, notions possessed by everybody”

(Aristoteles, Rhetorik, Buch I, Kapitel 1 (Alternativlink), in der Übersetzung von W. Rhys Roberts)

“we must be able to employ persuasion, just as strict reasoning can be employed, on opposite sides of a question, not in order that we may in practice employ it in both ways (for we must not make people believe what is wrong), but in order that we may see clearly what the facts are, and that, if another man argues unfairly, we on our part may be able to confute him.”

(Aristoteles, ebd., m. Hvh.)
