AbstractThis article explains the design and development of the pragma-dialectical approach to fallacies. In this approach fallacies are viewed as violations of the standards for critical discussion that are expressed in a code of conduct for reasonable argumentative discourse. After the problem-solving validity in resolving differences of opinion of the rules of this code has been discussed, their conventional validity for real-life arguers is demonstrated. Starting from the extended version of the theory in which the strategic maneuvering taking place in argumentative discourse is included, the article explains that the violations of the rules that are committed in the fallacies involve derailments of strategic maneuvering. This culminates in a discussion of the exploitation of hidden fallaciousness as an unreasonable way of increasing the effectiveness of argumentative discourse – a vital topic of research in present-day pragma-dialectics.

The aim of this paper is to describe the way in which argumentative patterns come into being in plenary debate over legislative issues in the European Parliament. What kind of argumentative patterns are to be expected within this macro context? It is shown that the argumentative patterns that come into being in legislative debate in the European Parliament depend for the most part on the problem-solving argumentation that is put forward in the opening speech by the rapporteur of the parliamentary committee report. This argumentation can be pragmatic problem-solving argumentation or complex problem-solving argumentation. The most important prototypical argumentative patterns are investigated in the argumentation put forward by the Members of parliament. This investigation is based on an inventory of the arguments that can in principle be used to support or attack the initial problem-solving argumentation put forward by the rapporteur.

The introduction of the concept of strategic maneuvering into the pragma-dialectical theory makes it possible to formulate testable hypotheses regarding the persuasiveness of argumentative moves that are made in argumentative discourse. After summarizing the standard pragma-dialectical approach to argumentation, van Eemeren, Garssen, and Meuffels explain what the extension of the pragma-dialectical approach with strategic maneuvering involves and discuss the fallacies in terms of the extended pragma-dialectical approach as derailments of strategic maneuvering. Then they give an empirical interpretation of the extended pragma-dialectical model in which they report the testing of three hypotheses which formulate preliminary conditions for effectiveness research within the framework of the extended pragma-dialectical theory and the results of the tests they consecutively carried out.

Schulz and Rubinelli's project 'Informed consent and strategic maneuvering in doctor-patient interaction' provides an excellent opportunity for studying argumentation in a specific institutional context because a medical consultation is a special communicative activity type that may involve argumentative discussion. Before engaging in empirical research regarding such a consultation it is necessary to make a conceptional analysis of this type of doctor-patient interaction. One first needs to give a general characterization of the type of interaction concerned: what is the structure of the interaction in a doctor-patient consultation in terms of speech acts, role taking and time constraints? For doing so a better understanding is required of the type of difference of opinion that will be at issue in such a consultation. What type of standpoint initiates the discussion? Which parts can be distinguished in the activity type of medical consultation and which of them are typically or potentially argumentative? What are the roles of the two participants in each of these cases? Is it the doctor or the patient who initiates the discussion by putting forward a standpoint or can this be done by either of them?
