The paper calls for argumentation theory to learn from moral and political philosophy. Several thinkers in these fields help understand the occurrence of what we may call legitimate dissensus: enduring disagreement even between reasonable people arguing reasonably. It inevitably occurs over practical issues, e.g., issues of action rather than truth, because there will normally be legitimate arguments on both sides, and these will be incommensurable, i.e., they cannot be objectively weighed against each other. Accordingly, ‘inference,’ ‘validity,’ and ‘sufficiency’ are inapplicable (...) notions. Further distinctive features of pro and con arguments in practical argumentation are explored, and some corollaries are drawn regarding evaluative norms of legitimate dissensus. Examples from immigrationrelated public debates in Denmark are given. (shrink)

Political debate is a distinctive domain in argumentation, characterized by these features: it is about proposals for action, not about propositions that may have a truth value; there may be good arguments on both sides; neither the proposal nor its rejection follows by necessity or inference; the pros and the cons generally cannot, being multidimensional and hence incommen- surable, be aggregated in an objective way; each audience member must subjectively compare and balance arguments on the two sides; eventual consensus between (...) the debaters is not a reasonable requirement. From all this follows a view of the rhetor’s special obligation in democratic, deliberative rhetoric on which it becomes crucial, in the interest of the audience, that political debaters acknowledge good arguments on the opposite side and explain why, on balance, they deem the arguments favoring their own side to be stronger.

Douglas Walton has done extensive and valuable work on the concepts of presumption and practical reasoning. However, Walton’s attempt to model practical reasoning as presumptive is misguided. The notions of “inference” and of the burden of proof shifting back and forth between proponent and respondent are misleading and lead to counterintuitive consequences. Because the issue in practical reasoning is a proposal, not a proposition, there are, in the standard case, several perfectly good reasons on both sides simultaneously, which implies that (...) argument appraisal necessarily contains a subjective element—a fact argumentation theory needs to conceptualize.

If there is a specifically rhetorical approach to argumentation, I believe it is one that studies argumentation that is specifically rhetorical. So if we want to ask, “What is the rhetorical approach to argumentation?” we should first ask, “What is rhetorical argumentation?” It is worthwhile focusing on this question because various misleading definitions of rhetorical argumentation have been in circulation for almost as long as rhetoric has existed. Some misleading definitions see the defining property of rhetorical argumentation in the arguer’s (...) aim. And that aim, which is often assumed to override all the arguer’s other considerations, is strategic: to persuade his hearer(s) by any available means and .. (shrink)

This introduction presents the set of six articles, written by rhetorical scholars, which constitute the bulk of the present special issue of Argumentation. In the introduction, the issue editor seeks to identify defining features of a rhetorical approach to argumentation. Taking this approach means dealing with argumentation in the “realm of rhetoric”, which comprises argumentation where deductive “demonstration” is not available. This has several corollaries, including the condition of uncertainty and the necessity of securing adherence from an audience. The articles (...) in the issue explore these and other characteristics of argumentation in the realm of rhetoric. (shrink)

Leading contemporary argumentation theories such as those of Ralph Johnson, van Eemeren and Houtlosser, and Tindale, in their attempt to address rhetoric, tend to define rhetorical argumentation with reference to (a) the rhetorical arguer’s goal (to persuade effectively), and (b) the means he employs to do so. However, a central strand in the rhetorical tradition itself, led by Aristotle, and arguably the dominant view, sees rhetorical argumentation as defined with reference to the domain of issues discussed. On that view, the (...) domain of rhetorical argumentation is centered on choice of action in the civic sphere, and the distinctive nature of issues in this domain is considered crucial. Hence, argumentation theories such as those discussed, insofar as they do not see rhetoric as defined by its distinctive domain, apply an understanding of rhetoric that is historically inadequate. It is further suggested that theories adopting this understanding of rhetoric risk ignoring important distinctive features of argumentation about action. (shrink)
