Using tools like argument diagrams and profiles of dialogue, this paper studies a number of examples of everyday conversational argumentation where determination of relevance and irrelevance can be assisted by means of adopting a new dialectical approach. According to the new dialectical theory, dialogue types are normative frameworks with specific goals and rules that can be applied to conversational argumentation. In this paper is shown how such dialectical models of reasonable argumentation can be applied to a determination of whether an (...) argument in a specific case is relevant are not in these examples. The approach is based on a linguistic account of dialogue and text from congruity theory, and on the notion of a dialectical shift. Such a shift occurs where an argument starts out as fitting into one type of dialogue, but then it only continues to makes sense as a coherent argument if it is taken to be a part of a different type of dialogue.

Develops a logical analysis of dialogue in which two or more parties attempt to advance their own interests. It includes a classification of the major types of dialogues and a discussion of several important informal fallacies.

The notions of types of dialogue and dialectical relevance are central themes in Walton’s work and the grounds for a dialectical approach to many fallacies. After outlining the dialogue models constituting the background of Walton’s account, this article presents the concepts of dialectical relevance and dialogue shifts in their application to biased argumentation, fallacious moves, and illicit argumentative strategies. Showing the different dialectical proposals Walton advanced in several studies on argumentation as a development of a dialogical system, it has proved (...) possible to highlight the fundamental aspects of his theory in a comprehensive model of communication and interaction.

Coherence in conversations and in texts can be partially characterized by a set of coherence relations, motivated ultimately by the speaker's or writer's need to be understood. In this paper, formal definitions are given for several coherence relations, based on the operations of an inference system; that is, the relations between successive portions of a discourse are characterized in terms of the inferences that can be drawn from each. In analyzing a discourse, it is frequently the case that we would (...) recognize it as coherent, in that it would satisfy the formal definition of some coherence relation, if only we could assume certain noun phrases to be coreferential. In such cases, we will simply assume the identity of the entities referred to, in what might be called a “petty conversational implicature,” thereby solving the coherence and coreference problems simultaneously. Three examples of different kinds of reference problems are presented. In each, it is shown how the coherence of the discourse can be recognized, and how the reference problems are solved, almost as a by‐product, by means of these petty conversational implicatures.

When we use a word, we face a crucial epistemic gap: we ground our move on the fact that our interlocutor knows the meaning of the word we used, and therefore he can interpret our dialogical intention. However, how is it possible to know the other’s mind? Hamblin explained this dialogical problem advancing the idea of dialectical meaning: on his view, the use of a word is based on a set of presumptions. Building on this approach, the use of a (...) word in a dialogue can be analyzed in terms of presumptive reasoning, while the manipulative strategies based on slanted or loaded terms or redefinitions can be conceived as forms of conflicts of presumptions. A presumptive approach to meaning can also ground different dialectical strategies to solve misunderstanding or definitional disagreements, or tactics to undermine the interlocutor’s arguments by advancing charges of equivocation.

This paper looks around among the major traditional fallacies — centering mainly around the so-called “gang of eighteen” — to discuss which of them should properly be classified as fallacies of relevance. The paper argues that four of these fallacies are fallacies primarily because they are failures of relevance in argumentation, while others are fallacies in a way that is more peripherally related to failures of relevance. Still others have an even more tangential relation to failures of relevance. This paper (...) is part of a larger research project on dialecical relevance in argumentative discourse, currently underway in collaboration with Frans van Eemeren and Rob Grootendorst. (shrink)

Stasis-theory seeks to classify rhetorical problems acccording to the underlying structure of the dispute that each involves. Such a classification is of interest to the practising rhetor, since it may help him identify an appropriate argumentative strategy; for example, patterns of argument appropriate to a question of fact may be irrelevant in an evaluative dispute.

Pragmatic presupposition is analyzed in this paper as grounded on an implicit reasoning process based on a set of presumptions, which can define cultural differences. The basic condition for making a presupposition can be represented as a reasoning criterion, namely reasonableness. Presuppositions, on this view, need to be reasonable, namely as the conclusion of an underlying presumptive reasoning that does not or may not contain contradictions with other presumptions, including the ordering of the hierarchy of presumptions. Presumptions are in turn (...) analyzed considering their nature and their hierarchy, namely their object and their possible contextual backing, which eliminates some of their possible defaults. This analysis of presupposition brings to light the relationship between communicative infelicities or misunderstandings deriving from presuppositional failures and the underlying system of presumptions and presumptive reasoning. This approach can be applied to the investigation of communicative problems within the medical context, and more precisely the communication in diabetes cases. (shrink)

In this article, we describe the notion of dialogue move intended as the minimal unit for the analysis of dialogues. We propose an approach to discourse analysis based on the pragmatic idea that the joint dialogical intentions are also co-constructed through the individual moves and the higher-order communicative intentions that the interlocutors pursue. In this view, our goal is to bring to light the pragmatic structure of a dialogue as a complex net of dialogical goals, which represent the communicative purposes (...) that the interlocutors intend to achieve through their utterances. Dialogue moves are shown to represent the necessary interpretive link between the general description of the dialogical context or type and the syntactical analysis of the sentences expressed by the individual utterances. In the concluding part of this article, we show how this method can be used and further developed for analyzing various types of real-life dialogues, outlining possible uses and lines of empirical research based thereon.

This is an introductory guidebook to the basic principles of how to construct good arguments and how to criticeze bad ones. It is non-technical in its approach and is based on 150 key examples, each discussed and evaluated in clear, illustrative detail. Professor Walton, a leading authority in the field of informal logic, explains how errors, fallacies, and other key failures of argument occur. He shows how correct uses of argument are based on sound strategies for reasoned persuasion and critical (...) responses. Among the many subjects covered are: forms of valid argument, relevance, appeals to emotion, personal attack, uses and abuses of expert opinion, problems in deploying statistics, loading terms, equivocation, arguments from analogy, and techniques of posing, replying to, and criticizing questions. The book will be ideally suited to courses in informal logic and in the introduction to philosophy. It will also prove valuable to studetns of pragmatics, rhetoric, and speech communication.

This book analyzes the uses of emotive language and redefinitions from pragmatic, dialectical, epistemic and rhetorical perspectives, investigating the relationship between emotions, persuasion and meaning, and focusing on the implicit dimension of the use of a word and its dialectical effects. It offers a method for evaluating the persuasive and manipulative uses of emotive language in ordinary and political discourse. Through the analysis of political speeches and legal arguments, the book offers a systematic study of emotive language in argumentation, rhetoric, (...) communication, political science and public speaking.

Fallacies of relevance, a major category of informal fallacies, include two that could be called pure fallacies of relevance-the wrong conclusion (ignoratio elenchi, wrong conclusion, missing the point) fallacy and the red herring digression, diversion) fallacy. The problem is how to classify examples of these fallacies so that they clearly fall into the one category or the other, on some rational system of classification. In this paper, the argument diagramming software system, Araucaria. is used to analyze the argumentation in some (...) selected textbook examples of pure fallacies of relevance. A system of classification of these fallacies is proposed, and criteria for determining whether an example should be classified as wrong conclusion or red herring are formulated. A key difference cited is that in a case where the red herring fallacy has been committed, even if the argument may go to a wrong conclusion, there is evidence of the use ofa deceptive tactic of diversion. Textual evidence must indicate that the arguer deliberately interjects a distracting controversy to lead the respondent away from the real issue to be disputed. (shrink)

This paper discusses several types of relevance criticism within dialogue. Relevance criticism is a way one could or should criticize one's partner's contribution in a conversation as being deficient in respect of conversational coherence. The first section tries to narrow down the scope of the subject to manageable proportions. Attention is given to the distinction between criticism of alleged fallacies within dialogue and such criticism as pertains to argumentative texts. Within dialogue one may distigguish tenability criticism, connection criticism, and narrow-type (...) relevance criticism. Only the last of these three types of criticism constitutes a charge of fallacy and carries with it a burden of proof. In the second it is observed that a full study of narrow-type relevance criticism would require the construction of complicated, many-layered, dialogue systems. Such a study can, however, be profitably preceded by setting up profiles of dialogue that help us discuss the ins and outs of certain types of move. This is illustrated with an example. (shrink)

Walton's book is a study of several fallacies in informal logic. Focusing on question-answer dialogues, and committed to a pragmatic rather than a semantic approach, he attempts to generate criteria for evaluating good and bad questions and answers. The book contains a discussion of such well-recognized fallacies as many questions, black-or-white questions, loaded questions, circular arguments, question-begging assertions and epithets, ad hominem and tu quoque arguments, ignoratio elenchi, and replying to a question with a question. In addition, Walton develops several (...) artificial dialogue games and has an excellent discussion of burden of proof in nonlegal contexts. The discussion is for the most part nontechnical and does not presuppose any training in formal logic. It is illustrated with many (sometimes overlong) examples of fallacies drawn from real life--mostly debates in the Canadian House of Commons. . . . Walton's book breaks new ground on a number of issues. Choice This first full-length study of logical fallacies, errors, faults, illicit attacks, blunders, and other critical deficiencies in interrogation and reply has been written in the tradition of informal fallacies in logic. It is especially valuable, readable, and interesting because of the 139 case studies it presents, many of these case studies come from political debates and some from interviews, legal cross-examinations, and other sources. Walton uses these challenging examples of tricky, aggressive, argumentative, or fallacious questions to develop coherent and pragmatic guidelines for criticizing questionable questions (and in some cases their replies) on logical grounds. Among the types of problematic questions analyzed are: the traditional so-called fallacy of many questions, illustrated by the famous Have you stopped beating your wife?; black and white questions; terminologically loaded questions; and questions containing personal attacks. These and other types of problematic questions as well as evasive replies and replying to a question with a question are studied. Critical errors of reasoning are identified and analyzed by developing context-based, normative models of reasonable dialogue in which a questioner must have freedom to ask informative and probing questions, and the respondent must be constrained to give reasonably direct, not overly evasive answers. In this era of negative and evasive political campaigning, with candidates employing skillful tactics of manipulating public opinion to assure election rather than taking clear stands and seriously debating issues in an informed and sincere manner, Question-Reply Argumentation is especially relevant reading for those who take democracy seriously. The methods used reflect a significant shift from earlier semantically based theories to current pragmatic, dialogue-based models, and will be of interest to logicians and linguists. The volume's conclusions should challenge some current preconceptions. Recommended reading for courses in logic, speech communications, linguistics, philosophy of language, areas of political science relating to political discourse and debate, courses on questioning in cognitive psychology, and courses on critical thinking in education.

It is widely accepted that there is a distinction to be made between the explicit content and the implicit import of an utterance. There is much less agreement about the precise nature of this distinction, how it is to be drawn, and whether any such two-way distinction can do justice to the levels and kinds of meaning involved in utterance interpretation. Grice’s distinction between what is said by an utterance and what is implicated is probably the best known instantiation of (...) the explicit/implicit distinction. His distinction, along with many of its post-Gricean heirs, is closely entwined with another distinction: that between semantics and pragmatics. Indeed, on some construals they are seen as essentially one and the same; “what is said” is equated with the truthconditional content of the utterance which in turn is equated with (context-relative) sentence meaning, leaving implicatures (conventional and conversational) as the sole domain of pragmatics.

Argument invention is a method that can be used to help an arguer find arguments that could be used to prove a claim he needs to defend. The aim of this paper is to show how argumentation systems recently developed in artificial intelligence can be applied to the task of argument invention. One such system called Carneades is featured. Carneades can be used to analyze arguments, evaluate arguments, to make an argument diagram, and to construct arguments from a database. Using (...) some simple examples, the paper explains how Carneades works as a system of argument invention. (shrink)

This paper presents a formal account of how to determine the discourse relations between propositions introduced in a text, and the relations between the events they describe. The distinct natural interpretations of texts with similar syntax are explained in terms of defeasible rules. These characterise the effects of causal knowledge and knowledge of language use on interpretation. Patterns of defeasible entailment that are supported by the logic in which the theory is expressed are shown to underly temporal interpretation.

This investigation uses the technique of the profile of dialogue as a tool for the evaluation of arguments from ignorance (also called lack-of-evidence arguments, negative evidence, ad ignorantiam arguments and ex silentio arguments). Such arguments have traditionally been classified as fallacies by the logic textbooks, but recent research has shown that in many cases they can be used reasonably. A profile of dialogue is a connected sequence of moves and countermoves in a conversational exchange of a type that is goal-directed (...) and can be represented in a normative model of dialogue. Selected case studies are used to probe special features of using the profile technique as applied to arguments from ignorance of a kind that occur frequently in everyday conversational exchanges. One of these special features is the use of Gricean implicature. Another is the need to use negative profiles of argument. (shrink)
