چکیده

The standard account of denying the antecedent (DA) is that it is a deductively invalid form of argument, and that, in a conditional argument, to argue from the falsity of the antecedent to the falsity of the consequent is always fallacious. In this paper, we argue that DA is not always a fallacious argumentative strategy. Instead, there is a legitimate usage of DA according to which it is a defeasible argument against the acceptability of a claim. The dialectical effect of denying the antecedent is to shift the burden of proof back to the original proponent of a claim. We provide a model of this non-fallacious usage which is built upon pragmatic models of argumentation. Résumé: On décrit typiquement comme non valide et toujours fallacieux tout raisonnement dans lequel on infère la négation du conséquent d’une proposition conditionnelle à partir de la négation de son antécédent (NA). J’avance dans cet article que ce raisonnement n’est pas toujours une stratégie argumentative fallacieuse. Il y a un usage légitime de NA selon lequel il est un argument réfutable contre l’acceptabilité d’un énoncé. L’effet dialectique de NA est de renvoyer la charge de preuve à la personne qui a premièrement avancé l’énoncé. J’emploie des cas exemplaires d’argumentation pragmatique pour décrire un modèle de cet usage non fallacieux. © Informal Logic Vol. 24, No. 3 (2004): pp. 219-243

Towards a Semantics for Argumentative Systems∗

Defeasible argumentation is one of the approaches that attempt to address the challenges arising when we reason defeasibly, with several formalisms in the literature reaching a mature state. Nowadays, several of them started shifting their semantics towards a dialectical characterization. Therefore, we believe that a sufficiently generic model of the process of dialectical reasoning could also ...

A Critical Discussion Game for Prohibiting Fallacies

The study of fallacies is at the heart of argumentation studies. In response to Hamblin’s devastating critique of the state of the theory of fallacies in 1970, both formal dialectical and informal approaches to fallacies developed. In the current paper, we focus on an influential informal approach to fallacies, part of the pragma-dialectical theory of argumentation. Central to the pragma-dialec...

Combining Practical and Dialectical Commitments for Service Engagements

We understand a service engagement as a form of collaboration arising in a sociotechnical system (STS). Although STSs are fruitfully modeled using normative abstractions such as commitments, a conventional (practical) commitment can capture only part of the story, namely, a debtor’s promise to the creditor to bring about the consequent if the antecedent holds. In contrast, in a dialectical comm...
