The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are proposed for finding missing (...) reasons, for deductive arguments, e.g., semantic tableaux are suggested.

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 investigates the emotive (or expressive) meaning of words commonly referred to as “loaded” or “emotive,” which include slurs, derogative or pejorative words, and ethical terms. We claim that emotive meaning can be reinterpreted from a pragmatic and argumentative perspective, which can account for distinct aspects of ethical terms, including the possibility of being modified and its cancellability. Emotive meaning is explained as a defeasible and automatic or automatized evaluative and intended inference commonly associated with the use of specific (...) terms, which can be represented and assessed considering its logical structure and its defeasibility conditions. This automatic inference is conceived as part of the connotation of an ethical term, and is not necessarily stable. By means of quasi-definitions, it is possible to modify the emotive meaning while maintaining the descriptive one, automaticizing the inferences drawn from an ethical word. Through examples drawn from the recent US presidential campaign, we show how re-contextualization and emotive contexts can affect emotive meaning. (shrink)

When is an argument to be called one-sided? When is putting forward such an argument fallacious? How can we develop a model for critical discussion, such that a fallaciously one-sided argument corresponds to a violation of a discussion rule? These issues are dealt with within ‘the limits of the dialogue model of argument’ by specifying a type of persuasion dialogue in which an arguer can offer complex arguments to anticipate particular responses by a critic.

In this paper, a challenge is outlined for Walton’s recent analysis of the fallacy of poisoning the well. An example of the fallacy in action during a debate on affirmative action on a South African campus is taken to raise the question of how Walton’s analysis squares with the idea that disadvantaged parties in debates about race may be epistemically privileged . It is asked when the background of a participant is relevant to a debate and it is proposed that (...) a proper analysis of the poisoning the well will outline conditions under which making one participant’s background an issue in a debate would be legitimate and illegitimate. Expanding Walton’s analysis to deal with the challenge, it is concluded that calling into question a participant’s suitability to take part in a debate is never legitimate when it is based simply on a broad fact about their background (like their race or gender).

Reasoning about analogical arguments is known to be subject to a variety of cognitive biases, and a lack of clarity about which factors can be considered strengths or weaknesses of an analogical argument. This can make it difficult both to design empirical experiments to study how people reason about analogical arguments, and to develop scalable tutoring tools for teaching how to reason and analyze analogical arguments. To address these concerns, we describe WG-A (Warrant Game — Analogy), a framework for people (...) to analyze analogical arguments based on Bartha’s (2010) Articulation Model of analogical argumentation. We carry out two experiments designed to probe WG-A’s effectiveness in improving participants’ ability to reason about analogical arguments and argumentation in general, and argue that WG-A is a promising approach, though it is in need of further development.

The conference theme invites contrasts between objectivity and bias, since the two are commonly considered contraries. But there are a variety of meanings of the two and a corresponding variety of contraries. Thus there is a problem for any attempt to discuss bias and objectivity in relation to argument as a contrasting pair. Still, several senses of both terms relate to argumentation. I offer an inventory of them.

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)

John Cook Wilson (1849–1915) was Wykeham Professor of Logic at New College, Oxford and the founder of ‘Oxford Realism’, a philosophical movement that flourished at Oxford during the first decades of the 20th century. Although trained as a classicist and a mathematician, his most important contribution was to the theory of knowledge, where he argued that knowledge is factive and not definable in terms of belief, and he criticized ‘hybrid’ and ‘externalist’ accounts. He also argued for direct realism in perception, (...) criticizing both empiricism and idealism, and argued for a moderate nominalist view of universals as being in rebus and only ‘apprehended’ by their particulars. His influence helped swaying Oxford away from idealism and, through figures such as H. A. Prichard, Gilbert Ryle, or J. L. Austin, his ideas were also to some extent at the origin of ‘moral intuitionism’ and ‘ordinary language philosophy’ which defined much of Oxford philosophy until the second half of the twentieth-century. Nevertheless, his name and legacy were all but forgotten for generations after World War II. Still, his views on knowledge are with us today, being in part at work in the writings of philosophers as diverse as John McDowell, Charles Travis, and Timothy Williamson. (shrink)

By synthesizing the argumentation theory of new rhetoric with research on heuristics and motivated reasoning, we develop a conceptual view of argumentation based on reasoning motivations that sheds new light on the morality of decision-making. Accordingly, we propose that reasoning in eristic argumentation is motivated by psychological (e.g., anxiety reduction) or material (e.g., vested interests) gains that do not depend on resolving the problem in question truthfully. Contrary to heuristic argumentation, in which disputants genuinely argue to reach a practically rational (...) solution, eristic argumentation aims to defeat the counterparty rather than seeking a reasonable solution. Eristic argumentation is susceptible to arbitrariness and power abuses; therefore, it is inappropriate for making moral judgments with the exception of judgments concerning moral taboos, which are closed to argumentation by their nature. Eristic argumentation is also problematic for strategic and entrepreneurial decision-making because it impedes the search for the right heuristic under uncertainty as an ecologically rational choice. However, our theoretical view emphasizes that under extreme uncertainty, where heuristic solutions are as fallible as any guesses, pretense reasoning by eristic argumentation may be instrumental for its adaptive benefits. Expanding the concept of eristic argumentation based on reasoning motivations opens a new path for studying the psychology of reasoning in connection to morality and decision-making under uncertainty. We discuss the implications of our theoretical view to relevant research streams, including ethical, strategic and entrepreneurial decision-making. (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.

This paper attempts to integrate an agnotological taxonomy of “not-knowing” with argumentation theory. Given rhetoric’s emphasis on what arguers choose to make present for their audience, it is argued that the rhetorical approach is best suited to accommodate the proposed taxonomy. In doing so we can improve the capacities of both arguers and audiences to detect adverse elements such as prejudices, implicit biases, and ideologies, which can restrict an argument’s claim to objectivity.

Robust clinical decision-making depends on valid reasoning and sound judgment and is essential for delivering quality healthcare. It is often susceptible, however, to a clinician’s biases such as towards a patient’s age, gender, race, or socioeconomic status. Gender bias in particular has a deleterious impact, which frequently results in cognitive myopia so that a clinician is unable to make an accurate diagnosis because of a patient’s gender—especially for female patients. Virtue epistemology provides a means for confronting gender bias in clinical (...) decision-making and for correcting or even preventing its impact. The medical literature on cardiovascular and coronary heart disease is used to illustrate the role intellectual virtues can play in redressing the deleterious impact of gender bias on clinical decision-making and practice. Finally, questions are considered surrounding the pedagogy of intellectual virtues for medical students and practicing clinicians in order to provide quality care for patients, regardless of gender.

This paper offers a novel situational approach to study organizational justice in which the proposed unit of analysis is managerial behavior manifested in argumentation rather than employee justice perceptions. The currently dominant theoretical framework in justice research, which is built on justice perceptions, neglects the unique features of organizational order and vulnerability of procedural justice perceptions. As the procedural justice concept belongs chiefly to a spontaneous market order under which the rule of law is made possible, it is inappropriate to (...) transfer this concept to an organization in which the rule of authority is dominant. Therefore, except the limited legal domain in which managerial freedom is restrained by laws, procedural justice in organizations represents a mirage that can give rise to hypocritical managerial actions that can legitimate morally controversial outcomes via eristic tactics. In contrast, interactional justice is of great importance to organizations in that employees and organizations can ensure their rational economic exchanges without deception. However, current formulations of interactional justice often regard interactions as a palliative recipe designed to alleviate reactions to outcomes and not as a constituent of distributive justice. Perelman’s argumentation theory can offer a new conceptualization of interactional justice that addresses this gap. (shrink)

I argue that Kotzee’s model of meta- debate succeeds in identifying illegitimate or fallacious charges of bias but has the unintended consequence of classifying some legitimate and non-fallacious charges as fallacious. This makes the model, in some important cases, counter-productive. In particular, cases where the call for a meta- debate is prompted by the participant with epistemic privilege and a charge of bias is denied by the participant with social advantage, the impasse will put the epistemically advantaged at far greater (...) risk. Therefore, I propose treating epistemic privilege as a variety of expert opinion specifically in cases where meta- debate participants come to an impasse in deliberation. My proposal exposes the problem of interpreting debate contexts as both adversarial and free from social power differentials. (shrink)

This study analyses how online participants of celebrity gossip position themselves in relation to their audience through forms of moral argumentation and thereby contribute to social hierarchies. In this study, forms of moral argumentation are seen as enthymemes, that is, claim-reason units based on moral norms as premises. The material consists of a total of 900 asynchronous online comments in English and 900 in Finnish. In addition to rhetorical argumentation analysis, the study investigates the dependency of moral argumentation on three (...) contextual variables: gendered violence as the topic of discussion, as the shared culture of participants and a media institution as the moderator of online discourse. Four forms of moral argumentation were found in the material: 1) theoretical, 2) practical, 3) categorical and 4) digital enthymeme. Theoretical, practical and categorical enthymemes are rhetorical in a traditional sense because they include the hierarchical idea of moral norms as the shared, more or less authoritarian, basis of a community. Digital enthymemes, conversely, are texts without clear borders or any notion of moral norms. Such arguments characterized especially user-generated, English-language discussions concerning female celebrities’ fights. This indicates that the digital enthymeme is particularly prevalent where there is a lack of obvious hierarchies in the context of argumentation. As this study argues, however, the seemingly non-hierarchical and individualistic participation through digital enthymemes is a mere illusion, for these enthymemes are based on crowd behaviour supportive of sexist and class-bound domination.

This paper uses the resources of illocutionary logic to provide a new understanding of the Liar Paradox. In the system of illocutionary logic of the paper, denials are irreducible counterparts of assertions; denial does not in every case amount to the same as the assertion of the negation of the statement that is denied. Both a Liar statement, (a) Statement (a) is not true, and the statement which it negates can correctly be denied; neither can correctly be asserted. A Liar (...) statement, more precisely, an attempted Liar statement, fails to fulfill conditions essential to statements, but no linguistic rules are violated by the attempt. Ordinary language, our ordinary practice of using language, is not inconsistent or incoherent because of the Liar. We are committed to deny Liars, but not to accept or assert them. This understanding of the Liar Paradox and its sources cannot be fully accommodated in a conventional logical system, which fails to mark the distinction between sentences/statements and illocutionary acts of accepting, rejecting, and supposing statements.

By presenting a case study based on the argumentative analysis of news in the press, this article introduces and discusses strategic manoeuvring with contextual frames. Drawing on the linguistic notion of frame, I introduce the concept of contextual frame to refer to the news context, that is, the background against which a certain event is presented as a piece of news. I argue that newspapers and journalists make use of contextual frames in the apparently neutral genre of news reporting to (...) propose specific interpretations of the facts at issue, which become the basis for explicit comments and editorials. To show how this works, I investigate in detail a case of newspaper coverage of a complex episode using the pragma-dialectical notion of strategic manoeuvring and the Argumentum Model of Topics to analyse argument schemes. I show that, in the use of contextual frames, there is a prominent relation between presentational devices and topical potential; contextual frames provide the implicit material premises which are at the basis of argumentations through which newspapers interpret and comment on the news.

Some current attempts to go beyond the narrow scope of rational choice theory (RCT) in the social sciences and the artificial reconstructions it sometimes provides focus on the arguments that people give to justify their beliefs and behaviors themselves. But the available argumentation theories are not constructed to fill this gap. This article argues that relevance theory, on the contrary, suggests interesting tracks. This provocative idea requires a rereading of Sperber and Wilson's theory. Actually, the authors do not explicitly support (...) RCT, and Sperber has even strongly criticized methodological individualism, which most of the time underlies RCT, in favor of infra-individualism. A key point of the argument presented here is to show that Sperber and Wilson do not firmly distinguish between infra-individualism and subintentionality. Only subintentionality is needed. Key Words: argumentation • rational choice • relevance theory • methodological individualism. (shrink)

In what follows, I strive to present the elements of a philosophical doctrine, which can be defined as dialectical contextualism. I proceed first to define the elements of this doctrine: dualities and polar contraries, the principle of dialectical indifference and the one-sidedness bias. I emphasize then the special importance of this doctrine in one specific field of meta-philosophy: the methodology for solving philosophical paradoxes. Finally, I describe several applications of this methodology on the following paradoxes: Hempel's paradox, the surprise examination (...) paradox and the Doomsday Argument. (shrink)
