I characterize the deductivist ideal of justification and, following to a great extent Toulmin’s work The Uses of Argument, I try to explain why this ideal is erroneous. Then I offer an alternative model of justification capable of making our claims to knowledge about substantial matters sound and reasonable. This model of justification will be based on a conception of justification as the result of good argumentation, and on a model of argumentation which is a pragmatic linguistic reconstruction of Toulmin’s (...) model of argument.

The analysis of multimodal argumentation in advertising is a crucial and problematic area of research. While its importance is growing in a time characterized by images and pictorial messages, the methods used for interpreting and reconstructing the structure of arguments expressed through verbal and visual means capture only isolated dimensions of this complex phenomenon. This paper intends to propose and illustrate a methodology for the reconstruction and analysis of “double-mode” arguments in advertisements, combining the instruments developed in social semiotics, pragmatics, (...) and argumentation theory. An advertisement is processed through a five-step path. The analysis of its context, text genre, and images leads to a first representation of the messages that it encodes both pictorially and verbally (step 1). These first semantic representations are further enriched by including their polyphonic articulations and presuppositions (step 2), their explicatures (step 3), and their dialogical functions and illocutionary forces (step 4). These pragmatic steps retrieve the commitment structure of the ad, which allows a further argument analysis conducted through argumentation schemes (step 5). (shrink)

The interpretation and the indirect reporting of a speaker’s communicative intentions lie at the crossroad between pragmatics, argumentation theory, and forensic linguistics. Since the leading case Masson v. New Yorker Magazine, Inc., in the United States the legal problem of determining the truth of a quotation is essentially equated with the correctness of its indirect reporting, i.e. the representation of the speaker’s intentions. For this reason, indirect reports are treated as interpretations of what the speaker intends to communicate. Theoretical considerations, (...) aimed at establishing the pragmatic meaning of an utterance and differentiating between presumptive and non-presumptive interpretation, are thus interwoven with the practical legal need of distinguishing a correct indirect report from an indirect one or a misquotation. An incorrect report or a misquotation has the dialectical effect of attributing to the misquoted party commitments that he never held, which the latter needs to rebut. This shifting of the burden of persuasion can be increased by using strategically the conflict between the presumptive interpretation of an utterance and the non-presumptive one, i.e. the different types of pragmatic ambiguity. When an interpreter is confronted with an utterance taken out of its dialogical context, his interpretative process is not guided by the actual context or intention, but rather the most frequent or prototypical dialogical setting or the most typical individual purpose that it could have served to achieve. This presumptive reconstruction can be used to provide a prima facie case that the other party needs to reject. The stronger the interpretative presumptions a speaker needs to rebut, the more effective the misquotation strategy. The conflict between the systematic and the presumptive process of interpretation can be represented as an argumentative mechanism of reconstruction of the individual intention, which allows one to assess the reasonableness of the interpretative reasoning.

From a critical rationalist perspective, I look at a fragment of the debate on shale gas exploration in the UK in order to make a proposal on the nature and representation of “conductive” argumentation, arguing it should not be viewed as a single argument, but in relation to deliberation as genre. There is no “conductive argumentation”, only various possible outcomes of deliberation, seen as critical testing of (alternative) proposals.

This book contains 20 essays tracing the work of David Zarefsky, a leading North American scholar of argumentation from a rhetorical perspective. The essays cohere around 4 general themes: objectives for studying argumentation rhetorically, approaches to rhetorical study of argumentation, patterns and schemes of rhetorical argumentation, and case studies illustrating the potential of studying argumentation rhetorically. These articles are drawn from across Zarefsky’s 45-year career. Many of these articles originally appeared in publications that are difficult to access today, and this (...) collection brings the reader up to date on the topic. Zarefsky’s scholarship focuses on the role of language in political argumentation, the ways in which argumentation creates public knowledge and belief, the influence of framing and context on what is said and understood, the deployment of particular patterns and schemes of argumentation in public reasoning, and the influence of debate on politics and governance. All these topics are addressed in this book. Each of the conceptual essays includes brief application to specific cases, and five extended case studies are also presented in this volume. The case studies cover different themes: two explore famous political debates, the third focuses on presidential rhetoric across the course of United States history, the fourth on the arguments for liberalism at a time of political polarization, and the fifth on the contemporary effort to engage the United States with the Muslim world. This book is of interest to scholars in the fields of philosophy, logic, law, philosophy of law, and legal history. The range of topics and concepts addressed, the interplay of concepts and cases and the unifying perspective of rhetorical argumentation make this book a valuable read for students of argumentative practice, whether rhetorically or otherwise.

This volume focuses on dialogue and argumentation in contexts which are marked by truculence and discord. The contributors include well known argumentation scholars who discuss the issues this raises from the point of view of a variety of disciplines and points of view. The authors seek to address theoretically challenging issues in a way that is relevant to both the theory and the practice of argument. The collection brings together selected essays from the 2006 11th Wake Forest University Biennial Argumentation (...) Conference held at Florida Atlantic University in Boca Raton, Florida and the 2012 14th Wake Forest University Biennial Argumentation Conference held at Casa Artom in Venice, Italy. (shrink)

Authority arguments generate support for claims by appealing to an agent’s authority status, rather than to reasons independent of it. With few exceptions, the current literature on argument schemes acknowledges two basic authority types. The _epistemic_ type grounds in knowledge, the_ deontic_ type grounds in power. We review how historically earlier scholarship acknowledged an_ attractiveness-based_ and a _majority-based_ authority type as equally basic type. Crossing these with basic speech act types thus yields authority argument sub-schemes. Focusing on the_ epistemic-assertive_ sub-scheme (...) (‘an epistemic authority _A_ _E_ asserts a proposition _P_’), we apply a meta-level approach to specifying critical questions. Results improve the evaluation of this sub-scheme and show how similar improvements are obtainable for other schemes. (shrink)

Although political argumentation is not institutionalized in a formal sense, it does have recurrent patterns and characteristics. Its constraints include the absence of time limits, the lack of a clear terminus, heterogeneous audiences, and the assumption that access is open to all. These constraints make creative strategic maneuvering both possible and necessary. Among the common types of strategic maneuvering are changing the subject, modifying the relevant audience, appealing to liberal and conservative presumptions, reframing the argument, using condensation symbols, employing the (...) locus of the irreparable, and argumentative use of figures and tropes. It is difficult to evaluate strategic maneuvering in political argumentation, however, because the activity types dictate wide latitude for the arguers, so there are few cases of unquestionable derailment.

Mencius, the second sage of Confucianism after Confucius, is well known for his subtle argumentative skills. Mencius did not develop his own argumentation theory, but argumentation practices, including his political argumentation, have enormously inspired later scholars in China to develop argumentation theories. In this paper, we try to reconstruct Mencius’s political argumentation from perspectives of both strategic maneuvering developed by van Eemeren et al. in argumentation theory and truth-functional logic in formal logic. The aim is to manifest the Dao, a (...) rational balance among logical, dialectical and rhetorical dimensions in Mencius’s political argumentation. The results indicate that Mencius’s political argumentation is not only logically justified but also shown to have maneuvered strategically between reasonableness and effectiveness, and that human beings have a common ground of formal and substantial logos, which makes it possible for people from different cultural groups to communicate rationally.

Arguments with what are called "independent" or "convergent" premises are typically diagrammed by using an arrow between each premise and the conclusion. This makes diagramming objections to the reasoning difficult. It also obscures differences in argument structure. I suggest that a single arrow should be used for such arguments and that this is so even in the extreme form of independent premises when the argument is entirely unstructured. I then discuss the diagramming of objections.

This article analyses the fallacy of wrenching from context, using the dialectical notions of commitment and implicature as tools. The data, a set of key examples, is used to sharpen the conceptual borderlines around the related fallacies of straw man, accent, misquotation, and neglect of qualifications. According to the analysis, the main characteristics of wrenching from context are the manipulation of the meaning of the other’s statement through devices such as the use of misquotations, selective quotations, and quoting out of (...) context. The theoretical tools employed in the analysis are pragmatic theories of meaning and a dialectical model of commitment, used to explain how and why a standpoint is distorted. The analysis is based on a conception of fallacies as deceptive strategic moves in a game of dialogue. As a consequence, our focus is not only on misquotations as distortions of meaning, but on how they are used as dialectical tools to attack an opponent or win a dispute. Wrenching from context is described as a fallacy of unfairly attributing a commitment to another party that he never held. Its power as a deceptive argumentation tactic is based on complex mechanisms of implicit commitments and on their misemployment to improperly suggest an attribution of commitment. (shrink)

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.

In this paper we analyze the uses and misuses of argumentation schemes from verbal classification, and show how argument from definition supports argumentation based on argument from verbal classification. The inquiry has inevitably included the broader study of the concept of definition. The paper presents the schemes for argument from classification and for argument from definition, and shows how the latter type of argument so typically supports the former. The problem of analyzing arguments based on classification is framed in a (...) structure that reveals the crucial role it plays in the persuasion process. The survey of the literature includes the work of Hastings, Perelman, Kienpointner and Schiappa, but still finds much of value in Aristotle. Lessons drawn from Aristotle’s Topics are shown to be useful for developing new tools for assessing definitions and arguments from definition. (shrink)

Five errors that fit under the category of jumping to a conclusion are identified: (1) arguing from premises that are insufficient as evidence to prove a conclusion (2) fallacious argument from ignorance, (3) arguing to a wrong conclusion, (4) using defeasible reasoning without being open to exceptions, and (5) overlooking/suppressing evidence. It is shown that jumping to a conclusion is best seen not as a fallacy itself, but as a more general category of faulty argumentation pattern underlying these errors and (...) some related fallacies.

Hamblin distinguished between formal and descriptive dialectic. Formal normative models of deliberation dialogue have been strongly emphasized as argumentation frameworks in computer science. But making such models of deliberation applicable to real natural language examples has reached a point where the descriptive aspect needs more interdisciplinary work. The new formal and computational models of deliberation dialogue that are being built in computer science seem to be closely related to some already existing and very well established computing technologies such as problem (...) solving and decision making, but whether or how dialectical argumentation can be helpful to support these systems remains an open question. The aim of this paper is to examine some real examples of argumentation that seem to hover on the borderlines between deliberation, problem solving and decision making. (shrink)

Abstract This paper addresses the role that argumentation schemes and argument visualization software tools can play in helping to find and counter objections to a given argument one is confronted with. Based on extensive analysis of features of the argumentation in these two examples, a practical four-step method of finding objections to an argument is set out. The study also applies the Carneades Argumentation System to the task of finding objections to an argument, and shows how this system has some (...) capabilities that are especially useful.

This paper explains the importance of classifying argumentation schemes, and outlines how schemes are being used in current research in artificial intelligence and computational linguistics on argument mining. It provides a survey of the literature on scheme classification. What are so far generally taken to represent a set of the most widely useful defeasible argumentation schemes are surveyed and explained systematically, including some that are difficult to classify. A new classification system covering these centrally important schemes is built.

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.

What do we learn when we find out that an argument is logically incorrect? If logically incorrect means the same as not logically correct, which in turn means not having a valid logical form, it seems that we do not learn anything too useful—an argument which is logically incorrect can still be conclusive. Thus, it seems that it makes sense to fix a stronger interpretation of the term under which a logically incorrect argument is guaranteed to be wrong. In this (...) paper, we show that pinpointing this stronger sense is much trickier than one would expect; but eventually we reach an explication of the notion of logical incorrectness which we find non-trivial and viable.

El objetivo de este trabajo es proponer un concepto de agente crítico que dialogue con una práctica democrática deliberativa, considerando qué significa el acto de dar razones. Para tal efecto, en este trabajo se discute, primero, qué significaría ser crítico o tender hacia la criticidad tanto autorreferente como hacia terceros. Esta sección está apoyada principalmente con ideas provenientes de la teoría de la argumentación y de la lógica informal. En segundo término, se aborda el concepto de democracia deliberativa a la (...) luz de la sinergia conceptual que habría entre la participación -potencial- de un agente crítico en tal contexto sociopolítico. En esta sección se pasa revista a algunas de las ideas centrales de la teoría de la democracia deliberativa. Y en la tercera y última parte, se aborda el problema de dar y recibir razones discutiendo la propuesta semántica inferencialista de Brandom (2002, 2005) para observar de qué manera este acercamiento puede aportar a una teoría de la deliberación y a un concepto -y educación- de agente crítico. En las conclusiones se sintetizan las ideas principales y, además, se hace un contrapunto entre la noción de agencia, concepto que es importante en mi propuesta, y la noción de persona, concepto de especial valor en la teoría de la democracia deliberativa.

Twenty-five years ago, field theory was among the most contested issues in argumentation studies. Today, the situation is very different. In fact, field theory has almost disappeared from disciplinary debates, a development which might suggest that the concept is not a useful aspect of argumentation theory. In contrast, I argue that while field studies are rarely useful, field theory provides an essential underpinning to any close analysis of an argumentative controversy. I then argue that the conflicting approaches to argument fields (...) were in fact not inconsistent, but instead reflected different aspects of field practices. A coherent approach to field theory can be developed by considering the way that all aspects of argumentative practice develop based on the purposes of arguers in an argumentative context. I then extend that position to argue that a justifiable theory of argumentation, which makes claims beyond the descriptive, must have at its core an analysis of the way that purpose constrains argumentation practice. In this view, the ultimate justification of principles found in a prescriptive or evaluative theory of argument must be in the way those principles fulfill practical problem-solving purposes related to the epistemic function of argument.

The paper considers the role of modality in the rational reconstruction of standpoints and arguments. The paper examines in what conditions modal markers can act as argumentative indicators and what kind of cues they provide for the reconstruction of argument. The paper critically re-examines Toulmin’s hypothesis that the meaning of the modals can be analyzed in terms of a field-invariant argumentative force and field-dependent criteria in the light of the Theory of Relative Modality developed within linguistic semantics, showing how this (...) theory can provide a more adequate model for exploiting the modals as indicators. The resulting picture confirms Toulmin’s intuition only in part: on the one hand the modals are always relational in nature and dependent on a contextual conversational background of propositions; on the other hand only epistemic-doxastic modals directly express a speech-act level inferential relation between a set of premises and a standpoint. Other modalities express relations (e.g. causal or final relations) better seen as part of the content of the argument whose argumentative relevance depends on the argumentation scheme employed. Thus non-epistemic modals function as argumentative indicators only indirectly. (shrink)

The Argument Web is maturing as both a platform built upon a synthesis of many contemporary theories of argumentation in philosophy and also as an ecosystem in which various applications and application components are contributed by different research groups around the world. It already hosts the largest publicly accessible corpora of argumentation and has the largest number of interoperable and cross compatible tools for the analysis, navigation and evaluation of arguments across a broad range of domains, languages and activity types. (...) Such interoperability is key in allowing innovative combinations of tool and data reuse that can further catalyse the development of the field of computational argumentation. The aim of this paper is to summarise the key foundations, the recent advances and the goals of the Argument Web, with a particular focus on demonstrating the relevance to, and roots in, philosophical argumentation theory.

We argue that there are mutually beneficial connections to be made between ideas in argumentation theory and the philosophy of mathematics, and that these connections can be suggested via the process of producing computational models of theories in these domains. We discuss Lakatos’s work (Proofs and Refutations, 1976) in which he championed the informal nature of mathematics, and our computational representation of his theory. In particular, we outline our representation of Cauchy’s proof of Euler’s conjecture, in which we use work (...) by Haggith on argumentation structures, and identify connections between these structures and Lakatos’s methods.

This article explores the modalities by which referring to past discursive performance of adversaries within a continuous polemical exchange is used in ad hominem attacks. Our starting point holds that in the context of lengthy debates, participants and third-party listeners share a rhetorical memory, which, dynamic and subjective as it may be, allows for the evaluation of participants’ characters based on their perceived discursive performances. By analysing opinion articles related to the Israeli political debate, this study shows how drawing inference (...) from adversaries’ prior statements and conduct is used to compromise their credibility as participants in the polemical exchange. It is found that, alongside supporting arguments from inconsistent commitment, previous discursive performance is mobilized to discredit speakers’ epistemic authority and their moral legitimacy.

This paper focuses on an explanation in a newspaper article: why new European Union citizens will come to the UK from Eastern Europe (e.g., because of available jobs). Using a corpus-based method of analysis, I show how regular target readers have been positioned to generate premises in dialogue with the explanation propositions, and thus into an understanding of the explanation as an argument, one which contains a biased conclusion not apparent in the text. Employing this method, and in particular ‘corpus (...) comparative statistical keywords’, I show how two issues can be freshly looked at: implicit premise recovery; the argument/explanation distinction.

In this paper, the role played in learning to argue by an essential and yet under-researched epistemic and argumentative norm is discussed, namely, the consistency requirement. An argumentative intervention is presented, that is designed to enhance the understanding of this norm among high school students, to enable them to recognize contradictions in the process of argumentation and to familiarize them with the argumentative strategies related to the reductio ad absurdum. There follows a description of how the designed intervention was implemented (...) in two Italian high schools, which served as an exploratory case study, and the results obtained are discussed.

In this paper I focus on the fallacy known as Complex Question or Many Questions. After a brief introduction, in Sect. 2 I highlight its pragmatic dimension, and in Sect. 3 its dialectical dimension. In Sect. 4 I present two accounts of this fallacy developed in argumentation theory, Douglas Walton’s and the Pragma-Dialectics’, which have resources to capture both its pragmatic and its dialectical nature. However, these accounts are unsatisfactory for various reasons. In Sect. 5 I focus on the pragmatic (...) dimension of the fallacy and I suggest amendments to the accounts mentioned drawing on the study of the phenomenon of presupposition in theoretical pragmatics. I argue that the central notion in the definition of the fallacy is that of an informative presupposition. In Sect. 6 I focus on the dialectical dimension of the fallacy. This dimension needs to be explicitly acknowledged in the definition of the fallacy in order to distinguish it from a different, non-dialectical, fallacious argumentative move involving presuppositions.

That bootstrapping and Moorean reasoning fail to instantiate persuasive argumentation is an often informally presented but not systematically developed view. In this paper, I will argue that this unpersuasiveness is not determined by principles of justification transmission but by two straightforward principles of rationality, understood as a concept of internal coherence. First, it is rational for S to believe the conclusion of an argument because of the argument, only if S believes sufficiently many premises of the argument. Second, if S (...) doubts that a source O is reliable and believes that information i is delivered by O, then S rationally suspends judgment about the truth of i. This paper aims to accomplish two tasks. First, it provides a thorough analysis of why bootstrapping argumentation is not an instance of rational persuasion. Second, it contains a more general theory about preconditions and limits of persuasive argumentation. (shrink)

Even with the lack of consensus on the nature of an argument, the thesis that explanations and arguments are distinct is near orthodoxy in well-known critical thinking texts and in the more advanced argumentation literature. In this paper, I reconstruct two rationales for distinguishing arguments from explanations. According to one, arguments and explanations are essentially different things because they have different structures. According to the other, while some explanations and arguments may have the same structure, they are different things because (...) explanations are used for different purposes than arguments. I argue that both rationales fail to motivate a distinction between arguments and explanations. Since these are the only rationales for distinguishing arguments from explanations that I am prepared to take seriously, I don’t see why we should exclude explanations from being arguments. (shrink)

My purpose here is to describe a type of argument characterized by the fact that one of its premises is a directive—i.e. what is expressed by a directive sentence: a general instruction how to proceed or act. This directive premise brings an ostensive mechanism for the inclusion of visual or multimodal elements in an argument. If an argument is an invitation to inference, by using such a directive utterance the addresser is inviting the addressee to make an inference from an (...) image, not from a proposition. Hence I will call them arguments from ostension or from deixis. (shrink)

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.

In this paper we present an analysis of persuasive definition based on argumentation schemes. Using the medieval notion of differentia and the traditional approach to topics, we explain the persuasiveness of emotive terms in persuasive definitions by applying the argumentation schemes for argument from classification and argument from values. Persuasive definitions, we hold, are persuasive because their goal is to modify the emotive meaning denotation of a persuasive term in a way that contains an implicit argument from values. However, our (...) theory is different from Stevenson’s, a positivistic view that sees emotive meaning as subjective, and defines it as a behavioral effect. Our proposal is to treat the persuasiveness produced by the use of emotive words and persuasive definitions as due to implicit arguments that an interlocutor may not be aware of. We use congruence theory to provide the linguistic framework for connecting a term with the function it is supposed to play in a text. Our account allows us to distinguish between conflicts of values and conflicts of classifications. (shrink)

Presuppositions are at the same time a crucial and almost neglected dimension of arguments and fallacies. Arguments involve different types of presuppositions, which can be used for manipulative purposes in distinct ways. However, what are presuppositions? What is their dialectical function? Why and how can they be dangerous? This paper intends to address these questions by developing the pragmatic approaches to presupposition from a dialectical perspective. The use of presuppositions will be analyzed in terms of presumptive conclusions concerning the interlocutor’s (...) acceptance of a proposition, which can be assessed as reasonable or unacceptable. Their dialectical function is described in terms of dark side commitments attributed to a collective "voice" representing what is commonly shared. For this reason, they count as attempts to include the presupposed contents into the hearer’s commitment store, which in some circumstances can reverse the burden of proof. The different manipulative strategies grounded on controversial presuppositions will be examined by showing the distinct roles that the latter play and the relationship between the degrees of presuppositional implicitness and the speaker’s burden of retraction.

The purpose of this paper is to inquire into the relationship between persuasive definition and common knowledge (propositions generally accepted and not subject to dispute in a discussion). We interpret the gap between common knowledge and persuasive definition (PD) in terms of potential disagreements: PDs are conceived as implicit arguments to win a potential conflict. Persuasive definitions are analyzed as arguments instantiating two argumentation schemes, argument from classification and argument from values, and presupposing a potential disagreement. The argumentative structure of (...) PDs reveals different levels of disagreement, and different pos-sibilities of resolving the conflict or causing dialogical deadlock. (shrink)

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.

This paper is aimed at combining the advances in argumentation theory with the models used in the field of education to address the issue of improving students’ argumentative behavior by interacting with an expert. The concept of deeper or more sophisticated argumentative strategy is theoretically defined and used to advance two new coding schemes, based on the advances in the argumentation studies and aimed at capturing the dialectical, or structural, behavior, and the argumentative content of each dialogue unit. These coding (...) schemes are then applied for a qualitative analysis of a study designed to investigate how students’ argumentative behavior can be influenced by the interaction with an expert, who used specific types of attacks to the interlocutors’ positions. The twofold coding shows at which dialogical level expert–peer interactions can directly and more stably affect students’ argumentative behavior, and what effects such more sophisticated strategies can have on the discussion and the analysis of disagreements. In particular, this paper shows how a specific type of deep-level attack, the underminer, can open dialogues of a different level, focused on unveiling and debating background beliefs underlying a specific position.

Abstract: The article presents and critically discusses Walton's (and Reed's and Macagno's) argument scheme approach to a theory of good argumentation. In particular, four characteristics of Walton's approach are presented: 1. It presents normative requirements for argumentation in the form of argument schemes, i.e. relatively concrete type descriptions. 2. These schemata are enthymematic, i.e. they omit some of the premises required by other approaches. 3. The actual argument schemes are usually supplemented by critical questions. 4. The method is inductive, bottom-up, (...) gaining the normative schemata by abstraction from empirically collected groups of similar arguments. These characteristics, among others, are then discussed on the basis of four adequacy conditions: AC1: effectiveness in achieving the epistemic goal of obtaining and communicating justified acceptable opinions; AC2: completeness in capturing the good argument types; AC3: efficiency in achieving the goals; AC4: justification of the argument schemes. The discussion then reveals a number of weaknesses in Walton's argument schemes; among other things, they are neither effective (in the defined sense) nor truly justified. Contributing factors to these problems include the schema approach, i.e. not looking at the form of arguments, and the lack of epistemological foundations in the development of good types of arguments. However, the critical analyses reveal a better alternative: an epistemological approach based on epistemological principles. The article concludes with a detailed analysis of the scheme Practical Inference, which confirms the general criticism in detail. (shrink)

In this paper, I propose a logical-cognitive approach to argumentation and advocate an idea that argumentation presupposes that intelligent agents engaged in it are cognitively diverse. My approach to argumentation allows drawing distinctions between justification, conviction and persuasion as its different kinds. In justification agents seek to verify weak or strong coherency of an agent’s position in a dialogue. In conviction they argue to modify their partner’s position by means of demonstrating weak or strong cogency of their positions before a (...) ‘rational judge’. My approach to argumentation employs a ‘light’ version of Dung’s abstract argumentative frameworks. It is based on Stich’s idea of agents’ cognitive diversity the epistemic aspect of which is argued to be close to Pavilionis’s conception of meaning continuum. To illustrate my contributions I use an example based on the Kitchen Debate (1959) between Khrushchev and Nixon. (shrink)

This paper explores the interrelations between temporality and emotion in rhetorical argumentation. It argues that in situations of uncertainty argumentation affects action via appeals that invoke emotion and thereby translate the distant past and future into the situated present. Using practical inferences, a threefold model for the interrelation of emotion and time in argumentation outlines how argumentative action depends on whether speakers provide reasons for the exigence that makes a decision necessary, the contingency of the decision, and the confidence required (...) to act. Experiences and choices from the past influence the emotions experienced in the present and inform two intertemporal mechanisms that allow speakers and audiences to take the leap of faith that defines decision-making under uncertainty: retrospective forecasting and prospective remembering. Retrospective forecasting establishes a past–future–present link, whereas prospective remembering establishes a future-past-present link, and, together, the two mechanisms provide a situated presence that transcends the temporal constraints of uncertainty. Finally, the applicability of the model is illustrated through an analysis of a speech delivered by Danish Prime Minister Mette Frederiksen at the outset of the COVID-19 pandemic, a time where the need for decisive, yet argumentative action was crucial.

Wittgenstein did not claim that the ordinary language concept ‘game’ cannot be defined: he claimed that there are multiple definitions that can be adopted for special purposes, but no single definition applicable to all games. I will defend this interpretation of Wittgenstein’s position by showing its compatibility with a pragmatic argumentative view of definitions, and how this view accounts for the diversity of disagreeing game definitions in definitional disputes.

Arguments from analogy are pervasive in everyday reasoning, mathematics, philosophy, and science. Informal logic studies everyday argumentation in ordinary language. A branch of fuzzy logic, approximate reasoning, seeks to model facets of everyday reasoning with vague concepts in ill-defined situations. Ways of combining the results from these fields will be suggested by introducing a new argumentation scheme—a fuzzy analogical argument from classification—with the associated critical questions. This will be motivated by a case study of analogical reasoning in the virtual friendship (...) debate within information ethics. The virtual friendship debate is a disagreement over whether virtual friendships are genuine friendships. It will be argued that the debate could move away from its current impasse, caused by unproductive metaphysical and logical assumptions, if extant arguments are reinterpreted as fuzzy analogical arguments from classification, and subjected to a new set of critical questions which would replace the quest for facts of essence about friendship with an emphasis on empirical data, persuasion, and definitional power.

This essay presents a dialogical framework for treating philosophical disagreements as persuasion dialogues with analogical argumentation, with the aim of recasting philosophical disputes as disagreements over analogies. This has two benefits: it allows us to temporarily bypass conflicting metaphysical intuitions by focusing on paradigmatic examples, similarities, and the plausibility of conclusions for or against a given point of view; and it can reveal new avenues of argumentation regarding a given issue. This approach to philosophical disagreements is illustrated by studying the (...) role of argumentation by analogy in disputes over Lockean justifications of intellectual property rights, and disagreements over whether artificial agents should be treated as moral agents. Finally, a nonexhaustive list of possible global and local points of contention over analogical arguments is identified in order to highlight potential avenues of argumentation in disagreements over analogies.

The multidisciplinary provenance of bioethics leads to a variety of discursive styles and ways of reasoning, making the discipline vulnerable to criticism and unwieldy to the setting of solid theoretical foundations. Applied ethics belongs to a group of disciplines that resort to deliberation rather than formal argumentation, therefore employing both factual and value propositions, as well as emotions, intuitions and other non logical elements. Deliberation is thus enriched to the point where ethical discourse becomes substantial rather than purely analytical. Caution (...) must be exercised to avoid this formal permissiveness from accepting empty and incorrigible statements that are but flatus voci since they can neither be supported nor falsified. It is therefore suggested that deliberation in bioethics should comply with three sets of conditions: (1) Be understandable, truthful, honest and pertinent, as suggested by communicative ethics; (2) Allow for second order, thick judgements as suggested by pragmatism; (3) Abide by additional criteria as here proposed: Doxastic propositions should be bolstered by a cognitive element; statements should be specific and proportional to the issue at hand, and they should be arguable and coherent.

This comment to Leo Groarke`'s "Auditory Arguments: The Logic of ‘Sound’ Arguments" is a contribution to the better understanding of an auditory argument as a part of analysis of an argumentative discourse. The emphasis is on human sound i.e. prosodic features of spoken language and its argumentative function. Paper presents sort of “auditory dictionary” which might be of use in sound analysis. It also gives one possible solution of translating sound into words by using visual images as mediators.

The paper relates two different fields of research: the historiography of generative linguistics and argumentation theory, a central topic of which is the investigation of fallacies. Relating the two fields is a challenge: Since fallacies seem to be at the heart of the historiography of generative linguistics, any thorough evaluation of its present state of the art also involves accounting for fallacies. The paper applies Kertész and Rákosi’s p-model of plausible argumentation to a case study on heated discussions in the (...) historiography of generative linguistics. As a result, basic properties of fallacious argumentation are revealed and delimited from plausible argumentation in linguistic historiography. In addition, the paper also draws generalizable conclusions that may affect the historiography of other human sciences as well. (shrink)

Wellman identified three types of conductive arguments, the third of which contains both pro and counter-considerations in the same piece of reasoning. This paper provides a pragma-dialectical analysis of this type of argumentation, with special focus on argumentation reconstruction. It argues that the account of pro/con argumentation in the framework of argument-as-product has problems solvable by a pragma-dialectical approach. The paper asserts that pro/con argumentation should be analyzed as a dialectical strategy of a protagonist, where acknowledgement of counter-considerations shows that (...) the antagonist’s reasons have been taken into consideration, although the pro-considerations override them. Thus, the pro-considerations of pro/con argumentation should be interpreted as the protagonist’s overriding defeaters of the antagonist’s counter-arguments, the protagonist incorporating the latter as counter-considerations. The paper further argues that the pragma-dialectical framework needs an additional conceptual tool to properly reconstruct complex forms of pro/con argumentation. Finally, the pragma-dialectical approach to reconstruct pro/con argumentation has several advantages, especially to a more logical-structural approach to complex pro/con argumentation. (shrink)
