Classical Rhetoric and a Limit to Persuasion

Classical rhetoric was the first discipline concerned with persuasion and in fact still has a lot to offer. This is exemplified by a short discussion of the persuasive appeals known from classical rhetoric as well as the so-called ‘aptum-model’. It is suggested how these sets of rhetorical concepts may be developed into guidelines for persuasive design. Moreover, classical rhetoric can be related to social psychology in an interesting and informative way. This combination of classical and modern disciplines of persuasion however also suggests that there is an inherent limit to the power of persuasive strategies.
