Philosophy of Argument

Coordinator: Jean Wagemans

This research investigates key concepts in argumentation theory, such as ‘argumentation structure’, ‘argument type’, ‘stock issue’, and ‘fallacy’ from a historical and systematic perspective. Beyond reconstructing major contributions to the classical disciplines of dialectic and rhetoric, it explores how traditional conceptions of argument can be modified and extended to encompass forms such as metaphor, narration, multimodal argumentation, and polylogue. The theoretical insights gained from this research inform other LANCAR research lines, which use them to further develop advanced models of argument processing, assessment, and production.

Student projects

Supervisors: Jean Wagemans, José Plug, and Dean McHugh

Frank Goossens analyzes the “common core” of interpretative arguments in the motivations of judges in terms of the Periodic Table of Arguments and compares their reconstruction to Walton et al. (2008) ad hoc argumentation schemes on these interpretative arguments. This internship contributes to the systematic study of arguments in legal discourse.

Pilar Kurban combines theories of stock issues and argument types to investigate the characteristics of politicians’ debate contributions. She applies the developed analytical tool to annotate several motions on asylum policy proposed during plenary sessions in the Dutch parliament.

Roosmarijn Rentier studies the connection between Hinton’s (2021) procedural questions for evaluating arguments and the traditional names for fallacies. After compiling lists of procedural questions about the process, reasoning, and language of natural arguments, she utilizes ChatGPT as a heuristic tool to develop a systematic overview of the associated fallacy labels.

Ermioni Seremeta is developing linguistic models of the three types of statement (fact, value, policy). The results of this research internship inform the next version of the Argument Type Identification Procedure (ATIP) and contribute to the Annotating Argumentation in the Wild and KRINO projects.

Constructing a Periodic Table of Arguments (PTA)

Researcher: Jean Wagemans

Since Aristotle compiled a list of arguments in his debate manual, the Topica, philosophers and rhetoricians have proposed numerous taxonomies of arguments (topoi/loci), fallacies, and other means of persuasion. The Periodic Table of Arguments (PTA) aims to synthesize these traditional accounts into an overarching framework. By charting the many ways people try to convince one another, the PTA provides a systematic overview of the building blocks of persuasive discourse.

The argument classification framework of the PTA allows for generating formal(izable) descriptions of the properties of arguments that can be tailored to the purposes of a wide variety of research, such as creating annotated corpora of persuasive discourse, cognitive empirical research into how people process such discourse, and formal linguistic and computational research into argumentation and persuasion.

Who’s Afraid of Discursive Reasoning? Revisiting the Idea of Logic in Aristotle and Hegel

Researchers: Jacco Verburgt and Jean Wagemans

Famously, Bertrand Russell claims that “any person in the present day who wishes to learn logic will be wasting his time if he reads Aristotle or any of his disciples” (1946). This claim reflects a long-standing supremacy of “modern logic”, meaning symbolic or mathematical logic. In contrast, this research project explores the discursive virtues of more “traditional reasoning” by revisiting (a) Aristotle’s idea of syllogistic, notably his efforts at classifying the deductive forms of reasoning pertaining to both dialectic and demonstrative contexts, and (b) Hegel’s idea of logic as prima philosophia, notably his endeavors at providing a discursive groundwork extending throughout both the philosophy of nature and the philosophy of spirit. In doing so, the project aims to assess concrete examples of logical and philosophical argumentations from the past and present.
