This paper presents a dialogue system called Lorenzen–Hamblin Natural Dialogue (LHND), in which participants can commit formal fallacies and have a method of both identifying and withdrawing formal fallacies. It therefore provides a tool for the dialectical evaluation of force of argument when players advance reasons which are deductively incorrect. The system is inspired by Hamblin’s formal dialectic and Lorenzen’s dialogical logic. It offers uniform protocols for Hamblin’s and Lorenzen’s dialogues and adds a protocol for embedding them. This unification required (...) a reformulation of the original description of Lorenzen’s system to distinguish “between different stances that a person might take in the discussion”, as suggested by Hodges. The LHND system is compared to Walton and Krabbe’s Complex Persuasion Dialogue using an example of a dialogue. (shrink)

This paper serves as an introduction to the special issue on argumentative patterns in discourse, more in particular on argumentative patterns with pragmatic argumentation as a main argument that are prototypical of argumentative discourse in certain communicative activity types in the political, the legal, the medical, and the academic domain. It situates the studies of argumentative patterns reported in these papers in the pragma-dialectical research program. In order to be able to do so, it is first explained in which consecutive (...) stages the pragma-dialectical theorizing has developed, what the study of argumentative patterns involves, and why the identification of argumentative patterns represents a vital stage in the development of pragma-dialectics. The description of the theoretical innovations that are introduced and the exposition of their relationship with the standard and extended pragma-dialectical theory create a conceptual and terminological framework for understanding the background and the rationale of the current research projects.

In the academic community, predatory publishers are exploiting academic integrity and the open access publishing model. Academicians receive numerous spam e-mail messages inviting article submissions each day which deceive authors by promising fast review and publication. The content of these emails present arguments in a way to appear as legitimate and valid to grab the attention of authors. Therefore, the aim of this paper is to advance insights into the arguments deployed by fake journals in their attempt to convey specific (...) indexicalities of identity and truthfulness. As a result of thematic analysis of 50 email messages from such journals, this research drew on two main themes-explicit and implicit arguments and their most frequent subcategories which were formal lexicon/grammar and fast peer- reviewed process. These arguments were, further, mapped on to Toulmin’s Model of Argumentation to find out more about the strength of the information used to support their claim. Utilizing Toulmin’s model, the findings highlighted the fact that there were instances of discursive deviations or “hidden rebuttals” that revealed the predatory journals’ ingenuity. (shrink)
