This article aims tt providing some conceptual tools for dealing adequately with relevance in argumentative discourse. For this purpose, argumentative relevance is defined as a functional interactional relation between certain elements in the discourse. In addition to the distinction between interpretive and evaluative relevance that can be traced in the literature, analytic relevance is introduced as an intermediary concept. In order to classify the various problems of relevance arising in interpreting, analyzing and evaluating argumentative discourse, a taxonomy is proposed in (...) which the concept of relevance is differentiated along three co-ordinate dimensions: object, domain and aspect. With the help of this taxonomy, it can be shown that the problems of evaluative relevance with which the standard approach to fallacies cannot satisfactory deal can be more systematically approached within a pragma-dialectical framework. This is demonstrated for the argumentum and hominem, which is erroneously treated as a homogenous type of relevance fallacy in logico-centric analyses, so that cases where this is not justified must be treated as ad hoc exceptions.

Van Eemeren and Houtlosser concentrate on the tension inherent in argumentative discourse between the pursuit of success and the maintenance of reasonableness. They elaborate on their earlier claim that this tension leads to ‘strategic manoeuvring’ that can be explained by making use of insights from dialectic and rhetoric. As a new step in their treatment of strategic manoeuvring they take account of the fact that the manoeuvring always takes place in one of the various argumentative ‘activity types’ that can be (...) distinguished in argumentative practice. Unlike theoretical constructs such as a critical discussion and other ideal models, which are based on analytic considerations regarding the most pertinent presentation of the constitutive parts of a problem-valid procedure for carrying out a particular kind of discursive task, the activity types and their associated speech events are cultural artefacts that can be identified on the basis of careful empirical observation of argumentative practice. By concentrating on three conventionalised activity types that are more or less institutionalised, van Eemeren and Houtlosser show how strategic manoeuvring is affected by the opportunities and constraints of the activity type in which it takes place.
