The use of ambiguous expressions in argumentative dialogues can lead to misunderstanding and equivocation. Such ambiguities are here called active ambiguities . However, even a normative model of persuasion dialogue ought not to ban active ambiguities altogether, one reason being that it is not always possible to determine beforehand which expressions will prove to be actively ambiguous. Thus, it is proposed that argumentative norms should enable each participant to put forward ambiguity criticisms as well as self-critical ambiguity corrections, inducing them to improve their language if necessary. In order to discourage them from nitpicking and from arriving at excessively high levels of precision, the parties are also provided with devices with which to examine whether the ambiguity corrections or ambiguity criticisms have been appropriate. A formal dialectical system is proposed, in the Hamblin style, that satisfies these and some other philosophical desiderata

This paper examines arguments that take counter- considerations into account, and it does so from a dialogical point of view. According to my account, a counterconsideration is part of a critical reaction from a real or imagined opponent, and an arguer may take it into account in his argument in at least six fully responsive ways. Conductive arguments will be characterized as one of these types. In this manner, the paper aims to show how conducive, and related kinds of argument can be understood dialogically.

In lieu of an abstract, here is a brief excerpt of the content:Room for Maneuver When Raising Critical DoubtJan Albert Van Laar1When interlocutors start talking at cross-purposes it becomes less likely that they will be able to resolve their initial difference of opinion (Van Eemeren and Grootendorst 1992, 125). How much room should we give a party for rephrasing or revising her adversary’s standpoint in a manner that suits her individual purposes in the dialogue? Certainly, as textbooks in argumentation and critical thinking make clear, we should steer clear of erecting and attacking straw men (Ennis 1996, 172; Govier 1985, 109–12; Groarke, Tindale, and Fisher 1997, 123). Still, a critic in a discussion or debate should be given some room to maneuver in order to rephrase the arguer’s position in her own words or to get at the underlying position of the arguer. In this article, I will be dealing with this issue from the pragma-dialectical perspective of strategic maneuvering between the shared dialectical objective of resolving a difference of opinion and the individual rhetorical objective of persuading the other side. According to existing accounts of the straw man fallacy (Talisse and Aikin 2006; Van Eemeren and Grootendorst 1992; Walton 1996), the criterion for fallaciousness resides in whether or not the critic misrepresents or distorts the arguer’s actual position. In this article I intend to provide more detailed guidelines for critics: a critic distorts or [End Page 195] misrepresents a position when she changes the formulation or nature of the arguer’s standpoint, even though this contribution by her cannot be reconstructed as containing a proposal for a change that might be acceptable to the arguer.In section 2 I will elaborate on the notion of confrontational maneuvering, that is, of strategic maneuvering between the dialectical and rhetorical goals that arise from the confrontation stage of a critical discussion. In section 3 I will characterize the form of maneuvering where an antagonist reformulates or modifies the protagonist’s standpoint in an opportune way. In section 4 I will examine the conditions under which applications of maneuvering of this kind can be sound and legitimate from a dialectical perspective and relate these conditions to the straw man fallacy. In section 5 the results of the preceding sections will be applied to a case.2. Confrontational ManeuveringIn argumentative discourse, participants typically try to achieve two kinds of objectives. First, they try to be dialectically reasonable, and second, they are out for some kind of personal triumph. The act, by the critic, of reformulating or revising the arguer’s standpoint will be dealt with from this dual perspective of strategic maneuvering (Van Eemeren and Houtlosser 2000, 2003). In order to analyze and evaluate the maneuver under discussion, I will elaborate in this section, first, on the notion of critical discussion in order to clarify the meaning of dialectical reasonableness and fallaciousness; second, on the importance of reconstruction for understanding argumentative discourse; third, on the notion of a confrontation stage; and fourth, on the distinction between direct and indirect maneuvering. These notions will be applied as follows: critics have some room for maneuvering when raising critical doubt, even when they change the arguer’s position or formulation, because there are contexts of utterance within confrontations where such a contribution does allow for a reconstruction in such a way that the result is not a direct and fallacious confrontational maneuver but, rather, an indirect and dialectically reasonable one.According to the pragma-dialectical methodology developed by Van Eemeren and Grootendorst (1984, 1992, 2004), an argumentative discourse must be reconstructed and evaluated from the perspective of a critical discussion. A critical discussion is a normative procedure that starts from a difference of opinion and that is solely aimed at resolving this dispute on the merits of the case (as perceived by the participants). When following [End Page 196] this procedure, discussants start by putting their difference of opinion into words in the confrontation stage; they proceed by deciding on the procedural and material starting points in the opening stage and by exchanging arguments and criticisms in the argumentation stage; and then they bring their discussion to a close by deciding in the concluding stage on whether the initial...

The distinction between constitutive and regulative rules is applied to rules for critical discussion that have to do with the use of ambiguous expressions. This leads to a distinction between rule violating fallacies, by which one abandons a critical discussion, and norm violating fallacies, which are in a way admissible within a critical discussion. According to the formal model for critical discussion, proposed in this paper, fallacies of the norm violating type arc not prohibited. Instead, it provides discussants with devices to discuss fallacies and fallacy criticisms

We shall investigate the similarities and dissimilarities between old and new dialectic. For the ‘old dialectic’, we base our survey mainly on Aristotle’s Topics and Sophistical Refutations, whereas for the ‘new dialectic’, we turn to contemporary views on dialogical interaction, such as can, for the greater part, be found in Walton’s The New Dialectic. Three issues are taken up: types of dialogue, fallacies, and strategies. Though one should not belittle the differences in scope and outlook that obtain between the old and the new dialectic, the paper will show that in many respects the old dialectic foreshadows the new dialectic

Ridicule can be used in order to create concurrence as well as to en-hance antagonism. This paper deals with ridicule that is used by a critic when he is responding to a standpoint or to a reason advanced in support of a standpoint. Ridicule profits from humor’s good repu-tation, and correctly so, even when it is used in argumentative contexts. However, ridicule can be harmful to a discussion. This paper will deal with ridicule from the perspective of strategic maneuvering between the individual rhetorical objec-tive of effecting persuasion and the shared dialectical objective of resolving the dispute on its merits. In what ways can ridicule be used in strategic maneuvering and under what conditions are these uses dialectically sound?

Some critical reactions hardly give clues to the arguer as to how to respond to them convincingly. Other critical reactions convey some or even all of the considerations that make the critic critical of the arguer’s position and direct the arguer to defuse or to at least contend with them. First, an explication of the notion of a critical reaction will be provided, zooming in on the degree of “directiveness” that a critical reaction displays. Second, it will be examined whether there are normative requirements that enhance the directiveness of criticism. Does the opponent have in circumstances a dialectical obligation to provide clarifications, explanations, or even arguments? In this paper, it is hypothesized that the competitiveness inherent in critical discussion must be mitigated by making the opponent responsible for providing her counterconsiderations, if available, thus assisting the proponent in developing an argumentative strategy that defuses them
