This study examines how evidence is used differently in argumentative discourse compared to individual arguments. Applying a 1×2 crossover study design, 37 secondary school students were asked either to discuss a social issue with their partner before individually writing an essay outlining their opinion or, vice versa, first to discuss and then to write. As background information, they were provided with pieces of evidence with different levels of quality. Dialogs and essays were analyzed regarding (a) the type of evidence and (...) (b) the way evidence was used. Results showed that in their essays students referred more often to the pieces of evidence provided to them (shared evidence). In contrast, they used evidence more often to address the opposing viewpoint in dialogs by incorporating it in a more elaborated (clearer) line of reasoning. Findings suggest that dialogues are a more effective tool than individual writing production, and the study provides first hints regarding how to design curricula that will encourage students to use evidence in a more sophisticated way in their argumentation.

What should a virtue theory of argumentation say about fallacious reasoning? If good arguments are virtuous, then fallacies are vicious. Yet fallacies cannot just be identified with vices, since vices are dispositional properties of agents whereas fallacies are types of argument. Rather, if the normativity of good argumentation is explicable in terms of virtues, we should expect the wrongness of bad argumentation to be explicable in terms of vices. This approach is defended through analysis of several fallacies, with particular emphasis (...) on the ad misericordiam. (shrink)

Robert Kimball, in “What’s Wrong with Argumentum Ad Baculum?” (Argumentation, 2006) argues that dialogue-based models of rational argumentation do not satisfactorily account for what is objectionable about more malicious uses of threats encountered in some ad baculum arguments. We review the dialogue-based approach to argumentum ad baculum, and show how it can offer more than Kimball thinks for analyzing such threat arguments and ad baculum fallacies.

This essay investigates the rhetorical choices in archived letters to providers at a local abortion clinic through argumentum ad baculum and other fear appeal frames. Analysis of three types of threat—spiritual, physical, and professional—contained in the correspondence suggests that only the professional fear appeals correspond to true theat. The essay contends that while some of the letters contain either true threats or Aristotelian civic fear appeals, the writers more often make arguments that align with a new category I name sideways (...) threats. Sideways threats include praeteritio or apophasis, whereby the writer renounces something like violence in order to invoke it, as well as fear appeals to negative outcomes which could be carried out by a deity rather than the writer. Rather than fitting neatly into the rhetorical categories of ad baculum or civic fear, these artifacts that included multiple rhetorical approaches which open the way for new understanding of fear appeals and their persuasive qualities.

The tradition of Nyāya philosophy centers on a dispassionate quest for truth which is simultaneously connected to soteriological and epistemic aims. This article shows how Vācaspati Miśra brings together the soteriological concept of dispassion with the discourse practices of debate, as a response to Buddhist criticisms in Dharmakīrti’s Vādanyāya. He defends the Nyāyasūtra’s stated position that fallacious reasoning is a legitimate means for a debate, under certain circumstances. Dharmakīrti argues that such reasoning is rationally ineffective and indicates unvirtuous qualities. For (...) Vācaspati, fallacies are a way to prevent the spread of morally weighty falsehoods when no other method is available to a debater. After showing textual relationships between Vācaspati’s defense and Dharmakīrti’s earlier criticism, it evaluates their arguments, concluding that Vācaspati’s position involves irresolvable tensions with other Nyāya commitments.

Argumentation virtue theory is a new field in argumentation studies. As in the case of virtue ethics and virtue epistemology, the study of virtue argumentation draws its inspiration from the works of Aristotle. First, I discuss the specifics of the argumentational virtues and suggest that they have an instrumental nature, modeled on the relation between the Aristotelian intellectual virtue of ‘practical wisdom’ and the moral virtues. Then, inspired by Aristotle’s discussion of akrasia, I suggest that a theory of fallacy in (...) argumentation virtue theory can be built upon the concept of ‘incontinence’. (shrink)
