Ridicule can be used in order to create concurrence as well as to en-hance antagonism. This paper deals with ridicule that is used by a critic when he is responding to a standpoint or to a reason advanced in support of a standpoint. Ridicule profits from humor’s good repu-tation, and correctly so, even when it is used in argumentative contexts. However, ridicule can be harmful to a discussion. This paper will deal with ridicule from the perspective of strategic maneuvering between (...) the individual rhetorical objec-tive of effecting persuasion and the shared dialectical objective of resolving the dispute on its merits. In what ways can ridicule be used in strategic maneuvering and under what conditions are these uses dialectically sound? (shrink)

Formal dialectic has its roots in ancient dialectic. We can trace this influence in Charles Hamblin’s book on fallacies, in which he introduced his first formal dialectical systems. Earlier, Paul Lorenzen proposed systems of dialogical logic, which were in fact formal dialectical systems avant la lettre, with roles similar to those of the Greek Questioner and Answerer. In order to make a comparison between ancient dialectic and contemporary formal dialectic, I shall formalize part of the Aristotelian procedure for Academic debates. (...) The resulting system will be compared (1) with Van Eemeren and Grootendorst’s system of rules of Critical Discussion (the pragma-dialectical discussion procedure), which must, however, first itself be reconstructed as a formal dialectical system, and (2) with a Hamblin-type system, and (3) a Lorenzen-type system. When drawing comparisons, it will become clear that there is a line to be drawn from Aristotle to formal dialectic and pragma-dialectics, extending to contemporary computational models of argument.

This paper makes an independent start with formalizing the rules for the argumentation stage of critical discussions. It does not deal with the well-known code of conduct consisting of ten rules but with the system consisting of fifteen rules on which the code of conduct is based. The rules of this system are scrutinized and problems they raise are discussed. Then a formal dialectical system is defined that reflects most of the contents of these rules. The aim is to elucidate (...) the way the rules work and to show how a formal approach can be useful to achieve this. It is also shown how the present method can be used to study the nature of circular argumentation. While, generally, the formalization follows closely the original rules for the argumentation stage of critical discussions, there will also be proposed some modifications of the original protocol.

This paper scrutinizes some peculiarities of the culture of Internet argumentation: it is a qualitative pragma-dialectical study of different strategies arguers employ to question or attack argumentation of their opponents in online political discussion forums. The basic assumption of the paper is that this particular context of argumentation—or: argumentative activity type—creates special opportunities and constraints for critical reactions regarding propositional content and relevance of argumentation. These opportunities and constraints, it is argued, may lead online discussions to being endless, yet not (...) necessarily fruitless from an argumentative perspective. (shrink)
