In response to an accusation of having said something inappropriate, the accused may exploit the difference between the explicit contents of their utterance and its implicatures. Widely discussed in the pragmatics literature are those cases in which arguers accept accountability only for the explicit contents of what they said while denying commitment to the implicature. In this paper, we sketch a fuller picture of commitment denial. We do so, first, by including in our discussion not just denial of implicatures, but (...) also the mirror strategy of denying commitment to literal meaning and, second, by classifying strategies for commitment denial in terms of classical rhetorical status theory. In addition to providing a systematic categorization of our data, this approach offers some clues to determine when such a defence strategy is a reasonable one and when it is not. (shrink)

In this overview article, we first explain what we take informal logic to be, discussing misconceptions and distinguishing our conception of it from competing ones; second, we briefly catalogue recent informal logic research, under 14 headings; third, we suggest four broad areas of problems and questions for future research; fourth, we describe current scholarly resources for informal logic; fifth, we discuss three implications of informal logic for philosophy in particular, and take note ofpractical consequences of a more general sort.

Informal logic began in the 1970s as a critique of then-current theoretical assumptions in the teaching of argument analysis and evaluation in philosophy departments in the U.S. and Canada. The last 35 years have seen significant developments in informal logic and critical thinking theory. The paper is a pilot study of the influence of these advances in theory on what is taught in courses on argument analysis and critical thinking in U.S. and Canadian philosophy departments. Its finding, provisional and much-qualified, (...) is that the theoretical developments and refinements have had limited impact on instruction in leading philosophy departments. (shrink)

In this paper, we look at reasoning with evidence and facts in criminal cases. We show how this reasoning may be analysed in a dialectical way by means of critical questions that point to typical sources of doubt. We discuss critical questions about the evidential arguments adduced, about the narrative accounts of the facts considered, and about the way in which the arguments and narratives are connected in an analysis. Our treatment shows how two different types of knowledge, represented as (...) schemes, play a role in reasoning with evidence: argumentation schemes and story schemes. (shrink)

Doug Walton, who died in January 2020, was a prolific author whose work in informal logic and argumentation had a profound influence on Artificial Intelligence, including Artificial Intelligence and Law. He was also very interested in interdisciplinary work, and a frequent and generous collaborator. In this paper seven leading researchers in AI and Law, all past programme chairs of the International Conference on AI and Law who have worked with him, describe his influence on their work.

The recent trend in institutional communication research seems to foster the image of the University as a private organization significantly oriented towards a policy of customer satisfaction. Following the concept of organizational culture, institutional settings too are conceived as organizational contexts, where discourse is a privileged vehicle to convey and spread values, traditions and artifacts, both through internal and external communication practices. Thus, within academic discourse organizational culture is shaped and perpetuated by specific devices of rhetorical argumentation. The corpus of (...) data consists of two different examples of academic discourse: the self promotional endorsement letters of the academic candidates to the chancellor’s position on occasion of the elections and the inaugural speeches proclaimed by the chancellors in charge during the opening celebration of the academic year. The first kind of academic discourse could be meant as an example of political discourse since the candidates use communication strategically and manipulate their academic membership as a rhetorical device to support their aims. On the other hand, the second example is a mere celebration of academic culture which through linguistic rituals recalls and perpetuates the basic values of this microcosm. The data have been analysed with the critical discourse analysis and diatextual analysis which pay particular attention to the context of speech. Moreover, attention has been focused on the metaphors and on the meta-discursive cues. The results show that although with different purposes academic discourse use similar discursive and rhetorical strategies as both belong to the same organization. (shrink)

Virtue theories have become influential in ethics and epistemology. This paper argues for a similar approach to argumentation. Several potential obstacles to virtue theories in general, and to this new application in particular, are considered and rejected. A first attempt is made at a survey of argumentational virtues, and finally it is argued that the dialectical nature of argumentation makes it particularly suited for virtue theoretic analysis.

Some authors have begun to appeal directly to studies of argumentation in their analyses of mathematical practice. These include researchers from an impressively diverse range of disciplines: not only philosophy of mathematics and argumentation theory, but also psychology, education, and computer science. This introduction provides some background to their work.

Disputational models of argumentation have been criticized as introducing adversariality into argumentation by mistakenly conceiving of it as minimally adversarial, and, in doing so, structurally incentivizing ancillary adversariality. As an alternative, non-adversarial models of argumentation like inquiry have been recommended. In this article I defend disputational, minimally adversarial models of disagreement-based argumentation. First, I argue that the normative kernel of minimal adversariality is properly located in the normative fabric of disagreement, not our practices of disputation. Thus, argumentation’s minimal adversariality is (...) a hereditary, rather than an acquired, trait. Second, I show how attempts to model disagreement-based argumentation non-adversarially, as co-inquiry, misrepresent the normative commitments of disagreers. Indeed, such attempts backfire in their efforts to make argumentation less adversarial, by removing the normative, discursive mechanisms by which we may hold each other to rational account for our commitments. Finally, I show how regulative models of disputation, like the Pragma-Dialectical critical discussion, are designed to minimize ancillary adversariality thereby preventing its escalation. (shrink)

Topical Themes in Argumentation Theory brings together twenty exploratory studies on important subjects of research in contemporary argumentation theory. The essays are based on papers that were presented at the 7th Conference of the International Society for the Study of Argumentation in Amsterdam in June 2010. They give an impression of the nature and the variety of the kind of research that has recently been carried out in the study of argumentation. The volume starts with three essays that provide stimulating (...) theoretical perspectives on argumentation. Subsequently, some views are explained on the intriguing topics of ‘dissensus’ and ‘deep disagreement’. After a discussion of three different approaches to the treatment of types of argumentation some classical themes from antique argumentation theory are revisited. The new research area of visual argumentation is explored in the next part. The volume concludes with three reports of experimental studies concerning argumentative discourse.

This book shows how research in linguistic pragmatics, philosophy of language, and rhetoric can be connected through argumentation to analyze a recognizably common strategy used in political and everyday conversation, namely the distortion of another’s words in an argumentative exchange. Straw man argumentation refers to the modification of a position by misquoting, misreporting or wrenching the original speaker’s statements from their context in order to attack them more easily or more effectively. Through 63 examples taken from different contexts (including political (...) and forensic discourses and dialogs) and 20 legal cases, the book analyzes the explicit and implicit types of straw man, shows how to assess the correctness of a quote or a report, and illustrates the arguments that can be used for supporting an interpretation and defending against a distortion. The tools of argumentation theory, a discipline aimed at investigating the uses of arguments by combining insights from pragmatics, logic, and communication, are applied to provide an original account of interpretation and reporting, and to describe and illustrate tactics and procedures that can be used and implemented for practical purposes.. This book will appeal to scholars in the fields of political communication, communication in general, argumentation theory, rhetoric and pragmatics, as well as to people working in public speech, speech writing, and discourse analysis.

Arguing that our attachment to Aristotelian modes of discourse makes a revision of their conceptual foundations long overdue, the author proposes the consideration of unacknowledged factors that play a central role in argument itself. These are in particular the subjective imprint and the dynamics of argumentation. Their inclusion in a four-dimensional framework and the focus on thesis validity allow for a more realistic view of our discourse practice. Exhaustive analyses of fascinating historical and contemporary arguments are provided. These range from (...) Columbus’s advocacy of the Western Passage to India, over the trial of King Louis XVI during the French Revolution, to today’s highly charged controversies surrounding euthanasia and embryo research. Excavating foundational issues such as the purpose of argument itself and the contested role of argument as a generator of knowledge, the book culminates in a discussion of the relationship between rationality and reasonableness and criticizes the restrictions of ‘rational’ argument relying on fixed logical, economic or cultural criteria that in reality are mutable. Here, a true, open argument requires the infusion of Paul Lorenzen’s principle of ‘transsubjectivity’, which recognizes but transcends the partiality of the individual and which can be seen in the pragmatic and expanding consensus that humanity can control itself to safeguard the future of a fragile, damaged world.

Drawing on insights from contemporary studies on conceptual metaphor and multimodal metaphor, the present study proposes a tentative analysis of multimodal metaphorical argument from the perspective of the extended theory of pragma-dialectics. A case, Liqun Commercial, is presented as an illustration. This commercial proves to use a conceptual metaphor, life is a journey, that underlies a multimodal metaphorical argument. The conceptual metaphor is highly acceptable in the cultural context of the Chinese target audience. Due to the restrictions imposed by the (...) institutional context, the commercial tries to convince the audience by using implicit argumentative means. In this endeavor, multimodal metaphorical argument is used to enhance the commercial’s effectiveness by foregrounding through framing the aspects the protagonist desires to show and by using a strategy to evade sanctions for ignoring institutional constraints.

I discuss under what conditions the objection that an expert’s argument is biased by her self-interest can be a meaningful and sound argumentative move. I suggest replacing the idea of bias qua self-interest by that of a conflict of interests, exploit the distinction between an expert context and a public context, and hold that the objection can be meaningful. Yet, the evaluation is overall negative, because the motivational role of self-interest for human behavior remains unclear. Moreover, if recent social-psychological results (...) from the “heuristics and biases” program are accepted, it is plausible to assume that humans also satisfice (rather than optimize/maximize) when identifying and then acting in their self-interest. My thesis is: insofar as the objection is sound with a particular audience, it is not needed; and insofar as the objection is needed, it is unsound. (shrink)

Whether abduction is treated as an argument or as an inference, the mainstream view presupposes a tight connection between abduction and inference to the best explanation. This paper critically evaluates this link and supports a narrower view on abduction. Our main thesis is that merely the hypothesis-generative aspect, but not the evaluative aspect, is properly abductive in the sense introduced by C. S. Peirce. We show why equating abduction with IBE unnecessarily complicates argument evaluation by levelling the status of abduction (...) as a third reasoning mode. We also propose a scheme for abductive argument along with critical questions, and suggest retaining abduction alongside IBE as related but distinct categories. (shrink)

Although debate is a richly structured and prevalent form of discourse, it has received little scholarly attention. Logicians have focused on the structure of individual arguments—how they divide into premises and conclusions, which in turn divide into various constituents. In contrast, I focus on the structure of sets of arguments, showing how arguments are themselves constituents in high-level dialectical structures. I represent debates and positions by graphs whose vertices correspond to arguments and whose edges correspond to two inter-argument relations: “dispute” (...) and “support,” respectively. On this basis I develop a theory of the structure of debate. (shrink)

Mencius, a prominent Confucian philosopher in the Warring States period of ancient China, is well-known for his argumentative skills, including his refutational skills used to maintain his own standpoints. This paper attempts to reveal how Mencius refuted his opponents argumentatively and strategically on the issue of human nature. To this end, the pragma-dialectical approach to argumentation is adopted to first reconstruct Mencius’s argumentative discourse on human nature according to the four stages in critical discussion—the confrontation, opening, argumentation and concluding stages. (...) Under the ancient Chinese historical and cultural context, Mencius’s argumentative discourse about human nature was developed in three critical discussions, between Mencius the protagonist, and his explicit interlocutors and implicit adversaries who held different views on human nature—the antagonists. The discussions were undertaken around three single mixed differences of opinion concerning three propositions, with resolution of the first difference of opinion serving as a starting point of the second, and the resolution of the second as a starting point of the third. Then based on the reconstruction, the paper elaborates the refutational strategies that Mencius employed in various stages, such as dissociation, reductio ad absurdum based on refutational analogy, and conciliation. It further points out that the employment of these strategies is strategic maneuvering undertaken by Mencius in an attempt to realize both dialectical and rhetorical aims. (shrink)

Some arguments are good; others are not. How can we tell the difference? This article advances three proposals as a partial answer to this question. The proposals are keyed to arguments conditioned by different degrees of uncertainty: mild, where the argument’s premises are hedged with point-valued probabilities; moderate, where the premises are hedged with interval probabilities; and severe, where the premises are hedged with non-numeric plausibilities such as ‘very likely’ or ‘unconfirmed’. For mild uncertainty, the article proposes to apply a (...) principle referred to as ‘Jeffrey’s rule’, for the principle is a generalization of Jeffrey conditionalization. For moderate uncertainty, the proposal is to extend Jeffrey’s rule for use with probability intervals. For severe uncertainty, the article proposes that even when lack of probabilistic information prevents the application of Jeffrey’s rule, the rule can be adapted to these conditions with the aid of a suitable plausibility measure. Together, the three proposals introduce an approach to argument evaluation that complements established frameworks for evaluating arguments: deductive soundness, informal logic, argumentation schemes, pragma-dialectics, and Bayesian inference. Nevertheless, this approach can be looked at as a generalization of the truth and validity conditions of the classical criterion for sound argumentation. (shrink)

The purpose of this research review is to examine the usefulness of reconstructing problematic interpersonal conflict behavior as violations of rules for critical discussions. Dialectical reconstruction of interpersonal conflict behavior sheds light on the ways in which dialectical fallacies influence not only the course of a critical discussion, but also the personal and relationship outcomes experienced by arguers. Conflict sequences such as cross complaining and demand/withdraw are shown to be problematic, in part, because they prevent parties from resolving their difference (...) through rational dialogue. The paper concludes by presenting some implications of the pragma-dialectical reconstruction of interpersonal conflict behavior. (shrink)

Addressing the slippery slope argument (SSA) in legal contexts from the perspective of pragma-dialectics, this paper elaborates the conditions under which an SSA-scheme instance is used reasonably (rather than fallaciously). We review SSA-instances in past legal decisions and analyze the basic legal SSA-scheme. By illustrating the institutional preconditions influencing the reasoning by which an SSA moves forward, we identify three sub-schemes (causal SSA, analogical SSA, and Sorites SSA). For each sub-scheme we propose critical questions, as well as four rules that (...) clarify when the SSA scheme is used reasonably. The institutional preconditions make the analogical SSA expectable in common law contexts; the Sorites SSA is expectable in civil law contexts; whereas the causal SSA is common to both contexts. This result should inform future work on the identification of typical argumentative patterns for the SSA in legal contexts. (shrink)

In this contribution, I will develop a comprehensive tool for the reconstruction and evaluation of argumentation from expert opinion. This is done by analyzing and then combining two dialectical accounts of this type of argumentation. Walton’s account of the ‘appeal to expert opinion’ provides a number of useful, but fairly unsystematic suggestions for critical questions pertaining to argumentation from expert opinion. The pragma-dialectical account of ‘argumentation from authority’ offers a clear and systematic, but fairly general framework for the reconstruction and (...) evaluation of this type of argumentation. The tool is developed by incorporating Walton’s critical questions into a pragma-dialectical framework. (shrink)

In this paper a dialogue game for critical discussion is developed. The dialogue game is a formalisation of the ideal discussion model that is central to the pragma-dialectical theory of argumentation. The formalisation is intended as a preparatory step to facilitate the development of computational tools to support the pragma-dialectical study of argumentation. An important dimension of the pragma-dialectical discussion model is the role played by speech acts. The central issue addressed in this paper is how the speech act perspective (...) can be accommodated in the formalisation as a dialogue game. The starting point is an existing ‘basic’ dialogue game for critical discussion, in which speech acts are not addressed. The speech act perspective is introduced into the dialogue game by changing the rules that govern the moves that can be made and the commitments that these result in, while the rules for the beginning, for the end, and for the structure of the dialogue game remain unchanged. The revision of the move rules is based on the distribution of speech acts in the pragma-dialectical discussion model. The revision of the commitment rules is based on the felicity conditions that are associated with those speech acts. (shrink)

Argument schemes are abstractions substantiating the inferential connection between premise(s) and conclusion in argumentative communication. Identifying such conventional patterns of reasoning is essential to the interpretation and evaluation of argumentation. Whether studying argumentation from a theory-driven or data-driven perspective, insight into the actual use of argumentation in communicative practice is essential. Large and reliably annotated corpora of argumentative discourse to quantitatively provide such insight are few and far between. This is all the more true for argument scheme corpora, which tend (...) to suffer from a combination of limited size, poor validation, and the use of ad hoc restricted typologies. In the current paper, we describe the annotation of schemes on the basis of two distinct classifications: Walton’s taxonomy of argument schemes, and Wagemans’ Periodic Table of Arguments. We describe the annotation procedure for each, and the quantitative characteristics of the resulting annotated text corpora. In doing so, we extend the annotation of the preexisting US2016 corpus of televised election debates, resulting in, to the best of our knowledge, the two largest consistently annotated corpora of schemes in argumentative dialogue publicly available. Based on evaluation in terms of inter-annotator agreement, we propose further improvements to the guidelines for annotating schemes: the argument scheme key, and the Argument Type Identification Procedure.

In ‘The making of argumentation theory’ van Eemeren and van Haaften describe the contributions made to the five components of a full-fledged research program of argumentation theory by four prominent approaches to the discipline: formal dialectics, rhetoric/pragmalinguistics, informal logic, and pragma-dialectics. Most of these approaches do not contribute to all components, but to some in particular. Starting from the pragma-dialectical view of the relationship between dialectical reasonableness and rhetorical effectiveness – the crucial issue in argumentation theory – van Eemeren and (...) van Haaften explain the positions taken by representatives from the approaches discussed and indicate where they differ from the pragma-dialectical approach. It transpires that approaches focusing on dialectical reasonableness are, next to pragma-dialectics, formal dialectics and informal logic; approaches focusing on rhetorical effectiveness are, next to pragma-dialectics, rhetoric and pragmalinguistics, and the informal logician Tindale. When it comes to the relationship between dialectical reasonableness and rhetorical effectiveness, some interest in it is shown in rhetoric and pragmalinguistics, but only in pragma-dialectics and in Tindale’s work is it a real focus. The main difference between Tindale’s view and the pragma-dialectical view is that in pragma-dialectics the decisive role in deciding about reasonableness is assigned to a code of conduct for reasonable argumentative discourse and in Tindale’s approach this role is assigned to Tindale’s interpretation of the Perelmanian universal audience.

This paper describes the development of pragma-dialectics as a theory of argumentative discourse. First the development of the pragma-dialectical model of a critical discussion is explained, with the rules that are to be complied with in order to avoid fallacies from occurring. Then the integration is discussed of rhetorical insight in the dialectical framework. In this endeavour, the concept of strategic manoeuvring is explained that allows for a more refined and more profoundly justified analysis of argumentative discourse and a better (...) identification of fallacies. The paper ends with a brief overview of current research projects. (shrink)

As an introduction to the special issue on Perspectives on Strategic Maneuvering, this article provides a synthetic recapitulation of the various steps that were taken in developing the pragma-dialectical theory of strategic maneuvering. First, the concept of strategic maneuvering is described as a means to reconcile the simultaneous pursuit of dialectical and rhetorical aims. Second, strategic maneuvering is related to the various kinds of argumentative activity types in which it takes place. Third, the concept of dialectical profiles is discussed and (...) the parameters that are pertinent to distinguishing between different types of strategic maneuvering. Fourth, the fallacies are viewed as derailment of strategic maneuvering. Fifth, as a case in point, strategic maneuvering with inconsistency is examined. (shrink)

In this article, after arguing that present approaches to improving problem-solving discussions for various reasons are not satisfactory, I turn to the pragma-dialectic approach to argumentative discourse to derive a normative framework that can serve as a point of departure to enhance the quality of problem-solving discussions. I then show how this approach can be used as analytical and evaluative instrument that can help the analyst to establish whether participants in actual practice act in a fashion that is in accord (...) with the norms posited. Two real-life problem-solving discussions provide the material for this demonstration. (shrink)

According to van Eemeren, argumentation theory is a hybrid discipline, because it requires a multidisciplinary, if not interdisciplinary approach, combining descriptive and normative insights. He points out that modern argumentation theorists give substance to the discipline by relying either on a dialectical perspective, concentrating on the reasonableness of argumentation, or on a rhetorical perspective, concentrating on its effectiveness. Both the dialectical and the rhetorical perspective are interpreted in ways related to how they were viewed by Aristotle, but in modern argumentation (...) theory the relationship between the two, captured in Aristotle’s term antistrophos, is lost. According to van Eemeren, this relationship, which he considers crucial to a full-fledged argumentation theory, has been recovered in extended pragma-dialectics with the help of the theoretical notion of ‘strategic manoeuvring.’.

This paper serves as an introduction to the special issue on argumentative patterns in discourse, more in particular on argumentative patterns with pragmatic argumentation as a main argument that are prototypical of argumentative discourse in certain communicative activity types in the political, the legal, the medical, and the academic domain. It situates the studies of argumentative patterns reported in these papers in the pragma-dialectical research program. In order to be able to do so, it is first explained in which consecutive (...) stages the pragma-dialectical theorizing has developed, what the study of argumentative patterns involves, and why the identification of argumentative patterns represents a vital stage in the development of pragma-dialectics. The description of the theoretical innovations that are introduced and the exposition of their relationship with the standard and extended pragma-dialectical theory create a conceptual and terminological framework for understanding the background and the rationale of the current research projects.

‘In Context’ is aimed at giving contextualization its rightful place in the study of argumentation. First, Frans H. van Eemeren explains the crucial role of context in a reconstructive analysis of argumentative discourse. He distinguishes four levels of contextualization. Second, he situates his approach to context in the field of argumentation studies by comparing it with Walton’s approach. He emphasizes the importance of distinguishing clearly between a normatively motivated theoretical ideal model and empirically-based communicative activity types. Third, van Eemeren concentrates (...) on the ‘macro-level’ of contextualization: contextualization in institutionalized communicative activity types. He makes clear that the macro-context of a communicative activity type can be characterized argumentatively by describing the disctinctive features of the empirical counterparts of the four stages of a critical discussion in the activity type concerned. Fourth, he points out what the consequences of the macrocontextualization of argumentative discourse in a certain communicative activity type are for the strategic maneuvering that may takes place and the identification of fallacies as derailments of strategic maneuvering. Fifth, van Eemeren draws some general conclusions regarding the role of contextualization in the analysis and evaluation of argumentative discourse. (shrink)

To illustrate the development of argumentation theory, the paper traces the journey of the pragma-dialectical theory as it widened its scope, step by step, from an abstract model of critical discussion to the complexities of actual argumentative discourse. It describes how, having contextualized, empiricalized and formalized their approach, pragma-dialecticians are now putting the theory’s analytical instruments to good use in identifying prototypical argumentative patterns in specific communicative activity types in the various communicative domains. This means that they can now start (...) answering the crucial question about the typical characteristics of their discourse asked by interested lawyers, politicians, academics and other practitioners of argumentation.

This theoretical expose explores the complex notion of argumentative style, which has so far been largely neglected in argumentation theory. After an introduction of the problems involved, the theoretical tools for identifying the properties of the discourse in which an argumentative style manifests itself are explained from a pragma-dialectical perspective and a theoretical definition of argumentative style is provided that does full justice to its role in argumentative discourse. The article concludes with a short reflection upon the next steps that (...) need to be taken in argumentation theory in further substantiating the notion of argumentative style. (shrink)

How does the analysis and evaluation of argumentation depend on the dialogue type in which the argumentation has been put forward? This paper focuses on argumentative bluff in eristic discussion. Argumentation cannot be presented without conveying the pretence that it is dialectically reasonable, as well as, at least to some degree, rhetorically effective. Within eristic discussion it can be profitable to engage in bluff with respect to such claims. However, it will be argued that such bluffing is dialectically inadmissible, even (...) within an eristic discussion. (shrink)

This paper provides a new interpretation of Plato’s account of justice as psychic health in Republic IV. It argues that what has traditionally been considered to be one single analogy is actually a more complex line of reasoning that contains various medical analogies. These medical analogies are not only different in number but also in kind. I discuss each of them separately, while providing a response to various objections.

Since a clear account of the fallacy of false disjunctive syllogism is missing in the literature, the fallacy is defined and its three types are differentiated after some preliminaries. Section 4 further elaborates the differentia specifica for each of the three types by analyzing relevant argument criticism of each, as well as the related profiles of dialogue. After defining false disjunctive syllogisms, it becomes possible to distinguish between a false dilemma and a false disjunctive syllogism: section 5 analyzes their similarities (...) and section 6 explains their differences.

False dilemma is a specific form of reasoning : despite the fact that it is based on a deductively valid argument form, it is rightly depicted as fallacy. A systematic exposition of false dilemma is missing in theoretical approaches to fallacies. This article formulates six criteria for a well-grounded exposition of a fallacy, suggesting also a systematic exposition of false dilemma. These criteria can be used to both explain, and categorise, the various false dilemma fallacies. The article introduces distinction between (...) four types of false dilemma : False quandary, Defeasible sound quandary, False obstruction and Defeasible sound obstruction. The types of criticism appropriate for each variant of false dilemma are suggested. Being able to discover false dilemma in situations when it is important to make good and free choices is a significant dimension of critical thinking. It may liberate us from accepting the consequences that necessarily follow from prearranged alternatives, when these are not the only alternatives possible. It may also liberate us from refraining from actions on the basis of obstructive disjunctive statements. In that respect, the faculty of critical thinking directed at uncovering reasoning based on false dilemma may also initiate the discovery of new alternatives, or discover the ways of unifying seemingly opposing alternatives. Thus, a well-developed ability to understand the tricky argumentative moves of false dilemma may be a good step towards initiating some features of creative thinking. (shrink)

Garssen and van Laar in effect concede our main criticism of the pragma-dialectical approach. The criticism is that the conclusions of arguments can be ‘P-D reasonable’ yet patently unreasonable, epistemically speaking. The concession consists in the claim that the theory “remains restricted to the investigation of standpoints in the light of particular sets of starting points” which are “up to individual disputants to create” and the admission that all the relevant terms of normative appraisal have been redefined. We also discuss (...) their criticisms of the epistemic account of argumentation and argument evaluation and raise some new questions about the approach they defend. (shrink)

While the role of discourse connectives has long been acknowledged in argumentative frameworks, these approaches often take a coarse-grained approach to connectives, treating them as a unified group having similar effects on argumentation. Based on an empirical study of the straw man fallacy, we argue that a more fine-grained approach is needed to explain the role of each connective and illustrate their specificities. We first present an original corpus study detailing the main features of four causal connectives in French that (...) speakers routinely use to attribute meaning to another speaker, which is a key element of straw man fallacies. We then assess the influence of each of these connectives in a series of controlled experiments. Our results indicate each connective has different effects for the persuasiveness of straw man fallacies, and that these effects can be explained by differences in their semantic profile, as evidenced in our corpus study. Taken together, our results demonstrate that connectives are important for argumentation but should be analyzed individually, and that the study of fallacies should include a fine-grained analysis of the linguistic elements typically used in their formulation.

As a way to advance integration between traditional readings of the medical encounter and argumentation theory, this article conceptualizes the doctor–patient interaction as a form of info-suasive dialogue. Firstly, the article explores the relevance of argumentation in the medical encounter in connection with the process of informed consent. Secondly, it discloses the risks inherent to a lack of reconciliation of the dialectical and rhetorical components in the delivery of the doctor’s advice, as especially resulting from the less-than-ideal conditions of the (...) internal states of the doctor and the patient, and the lack of symmetry in their status.

When analysing and evaluating discourse, the discourse itself, the speech event and the activity type it represents, forces the analyst to search for a theoretical and methodological framework which is suitable for analysing the activity exposed in the data. Interactive political argumentation demands both a theory of argumentation and a theory of spoken language to fully grasp what is going on in the discourse. The pragma-dialectical argumentation theory offers both analytical and evaluative tools, but rests upon a reconstruction of the (...) argumentative discourse which is hierarchical and static. If applied to interactive argumentation this kind of reconstruction will not reveal interactive aspects of the parties' argumentation. On the other hand, conversation analysis, which concentrates on interactive aspects of the discourse, does not offer a tool for the evaluation of the quality of each party's argumentation. (shrink)

Cuando enfrentan un escándalo, las empresas deben entablar una comunicación efectiva para intentar aminorar los efectos de la publicidad negativa sobre su imagen corporativa. Uno de los géneros empleados por las empresas como formas de discurso de reparación de la imagen es la declaración pública, que corresponde a un texto escrito corto emitido por una empresa con el propósito de comunicar su versión de la crisis que enfrenta directamente al público general, publicándola en el sitio web de la compañía, o (...) bien pagando una inserción en un periódico. El presente estudio, un estudio de casos múltiples, se propone determinar si la retórica empleada por las empresas chilenas cuando enfrentan un escándalo mediático, es decir, la forma en que argumentan y se defienden de las acusaciones de mala conducta, es ética y lícita desde la perspectiva de la ética empresarial. Para ello, se realizó un análisis crítico del manejo de la carga de la prueba en un corpus de veintiséis declaraciones públicas emitidas por empresas chilenas tras una crisis que empañó su imagen corporativa. Basándonos en la regla de la carga de la prueba propuesta desde la teoría pragma-dialéctica, y en algunos lineamientos para el diseño de códigos de ética corporativos planteados en la literatura se pudo determinar la validez de la argumentación retórica desplegada por las empresas. Los resultados muestran que la mayoría de las empresas evaden la carga de la prueba, lo que sugiere que estas empresas chilenas no se sienten obligadas a dar cuenta de sus acciones. El análisis ético revela que en la vasta mayoría de estas declaraciones no se emplea una retórica que evidencie un respeto hacia los afectados por la actividad de la empresa, especialmente hacia los consumidores, los trabajadores de la empresa y los competidores. Una de las conclusiones del estudio es que las empresas chilenas evidencian una concepción bastante limitada de lo que es la ética empresarial, que no considera los conceptos de transparencia ni responsabilidad pública y de control.

This work discusses an empirical study of reasoning as it occurs in conversations. Reasoning in this context has features not usually accounted for in standard methods for describing argumentation (e.g., Toulmin, (1964), Toulmin, Rieke, and Janik (1984)). For example, insufficient attention has been paid to challenges which can be used to shift the ground of an argument and to the development of multiple conversational grounds. Moreover, even though the value of cooperative efforts in building arguments is widely recognized, more needs (...) to be said about analyzing co-constructed arguments. This empirical work was primarily descriptive and concerned with how people construct arguments in conversations, but one goal of the study was to lay groundwork for comparing the quality of reasoning in conversations which differ with respect to whether the arguments they contain are primarily the contributions of individuals or are genuinely co-constructed arguments.

The present study examined how the pre-war debate of the US decision to invade Iraq (in March 2003) was discursively constructed in the US/British mainstream newspaper opinion/editorial (op/ed) argumentation. Drawing on theoretical insights from critical discourse analysis and argumentation theory, I problematised the fallacious discussion used in the pro-war op/eds to build up a ‘moral/legal case’ for war on Iraq based on adversarial (rather than dialogical) argumentation. The proponents of war deployed ‘instrumental rationality’ (ends-justify-means reasoning), ‘ethical necessity’ (Bush’s ‘Preemption Doctrine’) (...) and ‘humanitarian virtue’ (the bombing of Iraq to ‘save’ Iraqis from Saddam’s pestilent tyranny) to justify the pending invasion of Iraq. Their arguments intertextually resonated with Bush administration’s ‘war on terror’ rhetoric in a way that created a form of indexical association through ‘recontextualisation’. The type of arguments marshalled by the pro-war op/ed commentators uncritically bolstered the set of US official ‘truth claims’ and ‘presuppositions’. (shrink)

This paper throws some light on the nature of argumentation, its use and advantages, within the setting of doctor–patient interaction. It claims that argumentation can be used by doctors to offer patients reasons that work as ontological conditions for enhancing the decision making process, as well as to preserve the institutional nature of their relationship with patients. In support of these claims, selected arguments from real-life interactions are presented in the second part of the paper, and analysed by means of (...) a model of argumentation borrowed from classical rhetoric, and refined according to the modern orientation of the pragma-dialectic approach.
