    Don’t say that!
    Argumentation 20 (4): 495-510. 2006.
    According to pragma-dialectical methodology, a party in an argumentative discussion can be assumed to manoeuvre strategically between dialectical and rhetorical objectives. One confrontational form of strategic manoeuvring occurs when a critic charges an arguer with advancing a standpoint that has socially harmful consequences. In special situations this form of manoeuvring can be dialectically sound, for example when the standpoint is advanced in a way that damages the dialectical process. The …Read more

    Argument Schemes from the Point of View of Hamblin’s Dialectic
    Informal Logic 31 (4): 344-366. 2011.
    This paper aims at a normative account of non-deductive argumentation schemes in the spirit of Hamblin’s dialectical philosophy. First, three principles are presented that characterize Hamblin’s dialectical stance. Second, argumentation schemes, which have hardly been examined in Hamblin’s book Fallacies, shall be dealt with by applying these principles, taking an argumentation scheme from authority as the leading example. Third, a formal dialectical system, along the lines indicated by Hamblin,…Read more

    The Ways of Criticism
    with Erik C. W. Krabbe
    Argumentation 25 (2): 199-227. 2011.
    This paper attempts to systematically characterize critical reactions in argumentative discourse, such as objections, critical questions, rebuttals, refutations, counterarguments, and fallacy charges, in order to contribute to the dialogical approach to argumentation. We shall make use of four parameters to characterize distinct types of critical reaction. First, a critical reaction has a focus, for example on the standpoint, or on another part of an argument. Second, critical reactions appeal t…Read more

    Pragmatic Inconsistency and Credibility
    Argumentation 21 (3): 317-334. 2007.
    A critic may attack an arguer personally by pointing out that the arguer’s position is pragmatically inconsistent: the arguer does not practice what he preaches. A number of authors hold that such attacks can be part of a good argumentative discussion. However, there is a difficulty in accepting this kind of contribution as potentially legitimate, for the reason that there is nothing wrong for a protagonist to have an inconsistent position, in the sense of committing himself to mutually inconsis…Read more

    Ambiguity in argument
    Argument and Computation 1 (2): 125-146. 2010.
    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 critici…Read more

    Metadialogues: Krabbe’s Immanent Dialectic (review)
    with Peter Houtlosser
    Argumentation 21 (3): 205-208. 2007.
  •  25
    When interlocutors start to talk at cross purposes it becomes less likely that they will be able to resolve their differences of opinion. Still, a critic, in the confrontation stage of a discussion, should be given some room of manoeuvre for rephrasing and even for revising the arguer’s position. I will distinguish between licit and illicit applications of this form of strategic manoeuvring by stating three soundness conditions.

    Arguments that take Counterconsiderations into Account
    Informal Logic 34 (3): 240-275. 2014.
    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…Read more

    Room for maneuver when raising critical doubt
    Philosophy and Rhetoric 41 (3). 2008.
    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 argu…Read more

    Ambiguity in a Dialectical Perspective
    Informal Logic 21 (3). 2001.
    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, i…Read more

    About Old and New Dialectic: Dialogues, Fallacies, and Strategies
    with Erik C. W. Krabbe
    Informal Logic 27 (1): 27-58. 2007.
    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 tha…Read more
