In this article I defend what I call a ‘particularist approach to arguments by analogy.’ Particularism is opposed to generalism, which is the thesis that arguments by analogy require a universal principle that covers cases compared and guarantees the conclusion. Particularism rejects this claim and holds that arguments by analogy operate on particular cases. I elaborate on two ideas that support this position. On the one hand, I contend that an analogy can be seen as a parallelism of argumentative relationships, (...) drawing on the distinction between similarity and analogy (Gentner 1983) and on the meta-argumentative account of arguments by analogy (Woods and Hudak 1989). On the other hand, I argue that universal principles are not necessary neither for the analysis nor the evaluation of arguments by analogy (Govier 1989) and that, rather than being a requirement, they can be seen as by-products of good analogies.

This paper defends negotiation as a way of rationally overcoming disagreements. Negotiation is a type of dialogue where the parties begin with a conflict and a need for cooperation, and their main goal is to make a deal as reported (Walton and Krabbe 1995, p 72). It has been discussed whether differences of opinion can be shifted from persuasion to negotiation dialogue. If two parties disagree, is it reasonable to overcome their disagreement by employing negotiation? Van Laar and Krabbe (2018a) (...) argue that negotiation is the correct way to settle disagreements when the parties arrive at a stalemate. Godden and Casey (2020) deny this. They argue that the goal of persuasion dialogue (to resolve a conflict by verbal means) can never be replaced by a bargaining procedure. This paper claims that shifts to negotiation are reasonable, but only if the shift meets two conditions. The practical condition requires the disagreement to be practical rather than theoretical, and the sacrifice condition requires that the parties freely agree to shift the dialogue to negotiation. When the parties do not meet these conditions, they commit fallacies such as ad consequentiam, ad baculum or the fallacy of middle ground. Finally, I argue that negotiation arises in practical argumentation when the parties assign different relative values to their goals. When this process occurs, we see negotiation as a small step within the practical argumentation process. Persuasion, deliberation and negotiation dialogue are, then, deeply intertwined and are sometimes indistinguishable. (shrink)

This article presents an analysis and evaluation of what I call the “I’m not stupid” argument. This argument has ancient roots, which lie in Aristotle’s famous description of the weak man’s and strong man’s arguments. An “I’m not stupid” argument is typically used in a context of accusation and defense, by a defendant who argues that they did not commit the act of which they have been accused. The analysis of this type of argument takes the shape of an argumentative (...) pattern, which displays a full-fledged representation of its argumentation structure. It is based on a collection of ten contemporary instances of the “I’m not stupid” argument. Although ten instances constitute a small collection, the wide variation in the argumentative elements that they express explicitly or leave implicit made it possible to identify five new key premises in comparison with previous analyses of the weak man’s and strong man’s arguments (Walton, Tindale and Gordon 2014 in _Argumentation_ 28:85–119, 2014; Walton 2019 in _Argumentation_ 33:45–74, 2019). These new premises show that the crucial point of an evaluation of this argument is the arguer's supposedly rational character in making a gain-loss calculation. They also show that we need empirical data to strengthen our analyses of argument schemes and argumentation structures. (shrink)

We propose a revised definition of “argument scheme” that focuses on describing argumentative performances and normative assessments that occur within an argumentative context, the social context in which the scheme arises. Our premise-and-conclusion structure identifies the typical instantiation of an argument in the argumentative context, and our critical framework describes a set of normative assessments available to participants in the context, what we call _practically normative_ assessments. We distinguish this practical normativity from the _rationally or universally normative_ assessment that might (...) be imposed from outside the argumentative context. Thus, the practical norms represented in an argument scheme may still be subject to rational critique, and the scheme avoids the is/ought fallacy. We ground our theoretical discussion and observations in an empirical study of US district court opinions resolving legal questions about copyright fair use and the lawyers’ briefs that led to them, instantiating our definition of argument scheme in the “argument for classification by precedent.” Our definition addresses some criticisms the argument-scheme construct has received. For example, using our data, we show that a minimally well formed instance of this type of argument does not shift any conventional burden from the proponent of the argument to its skeptics. We also argue that these argument schemes need not be seen as dialogical. (shrink)

This paper aims to discuss a well-known concept from argumentation theory, namely the principle of charity. It will show that this principle, especially in its contemporary version as formulated by Donald Davidson, meets with some serious problems. Since we need the principle of charity in any kind of critical discussion, we propose the way of modifying it according to the presupponendum—the rule written in the sixteenth century by Ignatius Loyola. While also corresponding with pragma-dialectical rules, it also provides additional content. (...) This will be termed the dialectical principle of charity, and it offers a few steps to be performed during an argument in order to make sure that the participants understand each other well and are not deceived by any cognitive bias. The meaning of these results could be of great significance for argumentation theory, pragma-dialectics and the practice of public discourse as it enhances the principle of charity and makes it easier to apply in argumentation.

Recourse to meta-argument is an important feature of successful argument exchanges; it is where norms are made explicit or clarified, corrections are offered, and inferences are evaluated, among much else. Sadly, it is often an avenue for abuse, as the very virtues of meta-argument are turned against it. The question as to how to manage such abuses is a vexing one. Erik Krabbe proposed that one be levied a fine in cases of inappropriate meta-argumentative bids (2003). In a recent publication (...) (2022) Beth Innocenti expands on this notion of a penalty, arguing that some meta-arguments should be halted with “shouting, cussing, sarcasm, name-calling.” In this essay, we review Innocenti’s case that these confrontations and haltings improve the argumentative circumstances. We provide three reasons that this promise is not well-founded. First, that such confrontations have a significant audience problem, in that they are more likely to be interpreted as destroying the argumentative context than improving it. Second, that Innocenti’s procedural justification, that those who lose meta-discussions should pay a penalty, is not satisfied if the meta-discussion is halted. And third, there is a boundary problem for the cases, since it seems there is no principled reason to restrict halting meta-arguments just to these cases (especially if there is no meta-discussion on the matter to make the bounds explicit). Though expressions of anger can be appropriate in argument, we argue, it cannot take the place of argument. (shrink)

In IV, xvii, 19–22 of his Essay, Locke employs Latin labels for four kinds of argument, of which one (ad hominem) was already in circulation and one (ad judicium) has never had much currency. The present proposal seeks to locate and clarify what Locke was aiming to describe, and to contrast what he says with some subsequent uses that have been made of these labels as if they named fallacies. Though three of the four kinds of argument that Locke picks (...) out are often less than decisive, he casts no aspersion on the legitimacy of their use in debate. (shrink)

Critical questions have been understood in the framework of argument schemes from their conception. This understanding has influenced the process of evaluating arguments and the development of classifications. This paper argues that relating these two notions is detrimental to research on argument schemes and critical questions, and that it is possible to have critical questions without relying on argument schemes. Two objections are raised against the classical understanding of critical questions based on theoretical and analytical grounds. The theoretical objection presents (...) the assumptions that are embedded in the idea of argument schemes delivering questions to evaluate arguments. The analytical objection, on the other hand, exposes the shortcomings of the theory when critical questions are used to evaluate real-life argumentation. After presenting these criticisms, a new theory of critical questions is sketched. This theory takes into account the dynamics of dialectical discussions to describe the function of critical questions and their implications for evaluating arguments. (shrink)

TED Talks are still an unexplored genre of argumentation in which narrative arguments are often used in TED speakers’ strategic maneuvering to support a standpoint. In the present study, I combine the constructs of narrative positioning (NP) and strategic maneuvering (SM) to offer a conceptualization of how narrative is used in pragmatic argumentation as well as provide an exemplary analysis of a specific case of narrative arguments that were used in Winch’s (How to practice emotional first aid. https://www.ted.com/talks/guy_winch_the_case_for_emotional_hygiene.2014, 2014) TED (...) Talk. The proposed integration aims to provide a theoretical framework and empirical tools for reconstructing narrative arguments through connecting the underlying formal structure of narrative with aspects of TED speakers’ strategic maneuvering. Drawing on NP and SM constructs, the critical analysis explores how Winch’s narratives or “small stories” were strategically manipulated to support his stance with regard to the importance of mental health and to examine whether or not the use of narrative arguments as argumentation moves helped to enhance the dialectical reasonableness and rhetorical effectiveness of Winch’s argument. The analysis shows that the macro context and the knowledge gap between TED speakers and the audience makes the use of narrative arguments extremely effective. Although narrative arguments often receive criticism about their validity in providing sufficient evidence for a standpoint, their dialectical power lies in the flexibility of describing events in different fashions to draw pragmatic inferences that support the speaker’s stance. The study fills an important gap in the literature as it integrates recent approaches in narrative theory in the reconstruction and evaluation of narrative arguments in TED Talks. (shrink)

This argument explores transcultural commonalities among civic arguments from divination in global antiquity. In the ancient world, proponents engaged in kisceral arguments deriving from divinatory signs: arguments ex divinatione regarding prospective civic action. Under ideal circumstances, their aim was to help insure that the collective action of human political organizations was aligned with the natural synchrony of the cosmos. Thus, civic arguments from divination were employed to anticipate the future’s course based on the signs the system produced holistically. In ancient (...) Mesopotamia, China, and Rome, divination was employed as a tool for aligning the order of human society to that of a conception of metaphysical or cosmic order. By comparing these argumentative examples and rationales, we see a broader context for the way in which humans made arguments toward political futurity outside more conventional syllogistic formulations concerning causation. Rather, the argumentative strategies of many ancient cultures embraced an understanding of the future as the logical outcome of a holistic dynamism in kairotic time. (shrink)

Conditional constructions (if–then) enable us to express our thoughts about possible states of the world, and they form an important ingredient for our reasoning and argumentative capabilities. Different types and argumentative uses have been distinguished in the literature, but their applicability to actual language use is rarely evaluated. This paper focuses on the reliability of applying classifications of connections between antecedents and consequents of conditionals to discourse, and three issues are identified. First, different accounts produce incompatible results when applied to (...) language data. Second, a discrepancy between theory and data was observed in previous studies, which sometimes discard existing classifications for being detached from actual language use. Finally, language users construct various cognitive relations between clauses of conditionals without being able to rely on overt linguistic features, which poses problems for the annotation of conditionals in argumentation and discourse. This paper addresses these issues by means of comparing theoretical types and actual uses of conditionals, by inspecting the dispersion of types in natural-language corpora, and by conducting an experiment in which the inter-rater reliability of classifications was assessed. The results show that the reliability of classifications of conditionals when applied to language data is low. With respect to the aforementioned issues, different classifications produced incompatible results, a discrepancy between theory and data was indeed observed, and low reliability scores indicated a largely interpretative nature of types of conditionals. Given these results, suggestions for the enhancement of reliability in corpus studies of conditionals and beyond are provided to enhance future classification design. (shrink)

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.

The fallacy fallacy is either the misdiagnosis of fallacy or the supposition that the conclusion of a fallacy must be a falsehood. This paper explores the relevance of these and related errors of reasoning for the appraisal of arguments, especially within virtue theories of argumentation. In particular, the fallacy fallacy exemplifies the Owl of Minerva problem, whereby tools devised to understand a norm make possible new ways of violating the norm. Fallacies are such tools and so are vices. Hence a (...) similar problem arises with argumentative vices. Fortunately, both instances of the problem have a common remedy. (shrink)

Free speech fallacies are errors of meta-argument. One commits a free speech fallacy when one argues that since there are apparent restrictions on one’s rights of free expression, procedural rules of critical exchange have been broken, and consequently, one’s preferred view is dialectically better off than it may otherwise seem. Free speech fallacies are meta-argumentative, since they occur at the level of assessing the dialectical situation in terms of norms of argument and in terms of meta-evidential principles of interpreting how (...) and why people follow (or fail to follow) argumentative rules. Our plan here is to begin with a brief explanation of meta-argument and meta-argumentative fallacy. We will then turn to the variety of forms of the free speech fallacy, which we will explain as meta-argumentatively erroneous. (shrink)

This paper’s thesis is that the fallacies should not be taught to undergraduates. Besides some bad influences, this is not only because doing so steals time more valuably spent elsewhere, but also because the field is now so complex (overlapping concepts, theories and disciplines), that we lack knowledgeable instructors and sophisticated students. The study of theories involving fallacies, however, remains viable.

This essay begins with a brief description of my approach to the study of argumentation and fallacies which is empirical, historical-textual, dialectical, and meta-argumentational. It then focuses on the fallacy of composition and elaborates a number of conceptual definitions and distinctions: argument of composition; fallacy of composition; arguments and fallacies of division; arguments that confuse the distributive and collective meaning of terms; arguments from a property belonging to members of a group to its belonging to the entire group; several nuanced (...) schemes for arguments of composition; and several principles for the evaluation of such arguments. I then call attention to the fact that some scholars have claimed that the basic argument for global warming commits the fallacy of composition, and undertake a critical analysis of this claim. I show that the global-warming argument is not a fallacy of composition, but is rather a deductively valid argument of composition from the temperature of the parts to the temperature of the whole earth; moreover, I criticize the meta-argumentation of these scholars by showing that the global-warming argument is not similar to the one for global pollution, which is indeed fallacious; finally, I argue that these scholars confuse the global-warming argument with the argument claiming that all effects of global warming are harmful, which is indeed incorrect as a hasty generalization.

One takes one’s word that p when a source vouches for p and one accepts the word of that source. If the source is reliable in this case, p is acceptable. The reliability of the source is a measure of its plausibility. If a source has the relevant competence, credibility, authority, that word is acceptable. Likewise, the word may be acceptable if accompanied by a cogent argument, but presumption may be misplaced. One may recognize a presumption for a statement when (...) such recognition is not justified, the positive version of the fallacy. One may refuse to recognize a presumption for a statement when there really is a presumption for the statement, the negative version of the fallacy. The essay proceeds to explore various dimensions of when it is justified to take a source’s word for a claim, and when it is justified to reject a claim from a source. The discussion ranges over considerations of sexism and race, cultural differences, and the relationship of presumptions to fallacies. Also considered is the role of trust in taking someone’s word and the factors involved in trusting someone. (shrink)

This appearance condition of fallacies refers to the phenomenon of weak arguments, or moves in argumentation, appearing to be okay when really they aren’t. Not all theorists agree that the appearance condition should be part of the conception of fallacies but this essay explores some of the consequences of including it. In particular, the differences between committing a fallacy, causing a fallacy and observing a fallacy are identified. The remainder of the paper is given over to discussing possible causes of (...) mistakenly perceiving weak argumentation moves as okay. Among these are argument caused misperception, perspective caused misperception, discursive environment caused misperception and perceiver caused misperception. The discussion aims to be sufficiently general so that it can accommodate different models and standards of argumentation that make a place for fallacies. (shrink)

This short essay is an introduction to the essays included in this special issue of Argumentation devoted to fallacies.

In his Fallacies, Hamblin (1970) castigated what he called the “standard treatment” of fallacies in introductory textbooks of his day as debased, worn-out, dogmatic, and unconnected to anything else in modern logic. A bit more than 50 years later, I investigate the treatment of fallacies in six English-language introductory textbooks with a section on fallacies that have gone into 10 or more editions, to see whether their treatment of fallacies has taken account of the scholarship on fallacies that Hamblin’s book (...) evoked and is better than the treatment that Hamblin described. The answer is: not much. I conclude by setting out criteria for an adequate treatment of fallacies in an introductory textbook. (shrink)

The fallacies approach to argument evaluation can exacerbate problems it aims to address when it comes to social bias, perpetuating social injustice. A diagnosis that an argument commits a fallacy may flag the irrelevance of stereotypical characterizations to the line of reasoning without directly challenging the stereotypes. This becomes most apparent when personal bias is part of the subject matter under discussion, in ethotic argument, including ad hominem and ad verecundiam, which may be recognized as fallacious without addressing whether the (...) ethotic presumptions are true. Yap (2013; 2015) makes this case for ad hominem and the pragma-dialectical understanding of fallacies, expanded here to show related patterns in some other fallacies, and employing the argument schemes understanding of fallacies. Adding critical questions increases the ways reasoners can dismiss arguments as fallacious, and could include directly addressing bias, but if an argument fails on a different critical question, that may yet allow the bias to pass. The fallacies approach is a form of meta-debate and techniques of meta-debate need to address the ubiquity of social bias, not convey them as specialized problems. The view that the fallacies approach to argument evaluation can provide neutrality is dangerously false. Arguers thus should avoid using fallacies for argument evaluation where social stereotypes or schemas might be involved, especially when the subject matter relates closely to social justice.

This paper tries to offer a descriptive account of the normative workings of evaluative fallacy charges directed to narratives. In order to do that, I first defend the continuity and mutual dependence, as based on a dynamical conception of argument, between the ‘belief conception’ and the ‘argumentative conception’ of fallacy. Then, I construe a catalogue of ‘fallacy charges’ based on both such a continuity and the variety of counterarguments explored by the theoretical framework of Argument Dialectics. And finally, I apply (...) these ideas and distinctions in the analysis of four examples of published texts in which the charge of ‘fallacious narrative’ is issued by a discursive agent against other discursive agents’ either full-fledged narratives or narrative assumptions. The analyses confirm some of the characteristics mentioned in the catalogue as well as the argumentative nature of fallacy charges, even when the censored discourse does not exactly or explicitly contain an argument. The analyses also help understand the distinction between a rather concrete ‘linguistic’ use of the term narrative and a more abstract and elusive ‘discursive’ one, in which the difficulties of both identifying the object of censorship and the exact meaning of the fallacy charge multiply.

This article explains the design and development of the pragma-dialectical approach to fallacies. In this approach fallacies are viewed as violations of the standards for critical discussion that are expressed in a code of conduct for reasonable argumentative discourse. After the problem-solving validity in resolving differences of opinion of the rules of this code has been discussed, their conventional validity for real-life arguers is demonstrated. Starting from the extended version of the theory in which the strategic maneuvering taking place in (...) argumentative discourse is included, the article explains that the violations of the rules that are committed in the fallacies involve derailments of strategic maneuvering. This culminates in a discussion of the exploitation of hidden fallaciousness as an unreasonable way of increasing the effectiveness of argumentative discourse – a vital topic of research in present-day pragma-dialectics.

It has been said that there is no scholarly consensus as to why Aristotle’s logics of proof and refutation would have borne the title _Analytics._ But if we consulted Tarski’s (Introduction to logic and the methodology of deductive sciences, Oxford University Press, New York, 1941) graduate-level primer, we would have the perfect title for them: _Introduction to logic and to the methodology of deductive sciences._ There are two strings to Aristotle’s bow. The methodological string is the founding work on the (...) epistemology of science, and the logical string sets down conditions on the proofs that bring this knowledge about. The logic of proof presents a difficulty whose solution exceeds its theoretical reach. The logic of refutation takes the problem on board, and advances a solution whose execution is framed by fallacy-avoidance at the beginning and fallacy-adoption at the end. But with a difference: the avoidance-fallacies are of Aristotle’s own conception, whereas the adoption-fallacies, so judged in the modern tradition, aren’t fallacies at all for Aristotle. The avoidance-fallacies are begging the question and _ignoratio elenchi_, and the adoption-fallacies, fallacies in name only, are the _ad hominem_ and _ad ignorantiam_, an inductive turning in the first instance, and an abductive finish in the second.

Argumentation has remained under-researched in studies analyzing academic journal publications despite its importance in academic writing. This paper reports a study in which we investigated stereotypical argumentative trends, lexico-grammatical features, and interactional metadiscourse markers in 354 research article free-standing discussion sections from the journal of ESP over forty years. The field of ESP was chosen because of its maturity, which has given substance to a dynamic ground for arguments. We drew on the pragma-dialectical approach to analyzing argumentations in the corpus. (...) Findings indicated that due to the argumentative nature of the discussion section, certain argumentative trends recurred more often. The analysis of the lexico-grammatical features and metadiscourse markers of the standpoints also showed patterns of variability over time. The study concludes that it is imperative to incorporate relevant facets from various argumentation models to construct a comprehensive argumentation theory and gain deeper insights into argumentation in academic writing.

“Why are millions of dollars worth of orders being left unpaid?”. With tweets like this questioning brands’ policies, activists advocating for sustainable fashion re-discuss material starting points that are assumed by fashion brands, who argue that they are sustainable because they care about their workers’ conditions. This paper argues that activists use tweets to open _subdiscussions on material starting points_ to engage citizens and consumers, re-discussing factual _data_ that brands take for granted, such as the fact that they provide fair (...) conditions for their garment workers. Activists justify their opening of subdiscussions, often through an argumentative pattern that includes an argument based on the _locus from effects to cause_. They argue that if there are negative effects, the brand cannot claim to care about the conditions of its workers. In discussing how subdiscussions are used by fashion activists, this paper also introduces a conceptualization of Twitter argumentation as a discussion that is not isolated, but is part of a polylogical argumentation that takes place in different venues. For this reason, the argumentation used in tweets is reconstructed as a response to a fashion brand’s communication campaigns around sustainability, which extend beyond the confines of Twitter. As an empirical illustration, this paper is based on the campaign targeting fashion retailer Primark; the dataset includes the brand’s website as well as activists’ tweets. (shrink)

A Persistent Interlocutor (PI) is someone who, in argumentative contexts, does not cease to question her opponent’s premises. The epistemic relevance of the PI has been debated throughout the history of philosophy. Pyrrhonians famously claim that our inability to dialectically vindicate our claims against a PI implies scepticism. Adam Leite disagrees (2005). Michael Resorla argues that the debate is based on a false premise (2009). In this paper, I argue that these views all fail to accurately account for the epistemic (...) relevance of the PI. I then briefly present an account that aims to do better in this regard, based on the modal notion of safety. On the account proposed, the PI does not violate epistemic or dialectical norms. Rather, her behaviour tends to be epistemically perverse in the sense that it wastes cognitive resources. Perhaps surprisingly, this defect turns out not to be unique to the PI. (shrink)

Studies focusing on debate as pedagogy have been gaining attention recently. However, most research has employed policy debate, which is a traditional debate style. Parliamentary debate, which is an impromptu debate style, has been recently gaining popularity worldwide. As minimal research exists on parliamentary debate as pedagogy, the present study examined the correlations between parliamentary debate participation, communication competence, communication apprehension, argumentativeness, and willingness to communicate. Moreover, this study aimed to investigate the unique characteristics of communication variables and correlations with (...) the experience of participating in a parliamentary debate in a Japanese context, an area that interests many scholars. The results showed some differences in correlations between Japanese and United States samples, which was explained by analyzing a trait of Japanese culture that is characterized as highly contextual. Regarding the correlations between communication variables and parliamentary debate participation, significant differences were found for all variables except for communication competence, where less communication apprehension, more argument approach, less argument avoidance, and more willingness to communicate were observed compared to non-debaters. Finally, the study findings revealed that those with parliamentary debate experience obtained lower scores for communication apprehension and higher scores for argumentative approaches compared with those who did not have such experience; the effect sizes were smaller in women than men. These findings suggest that parliamentary debate participation is an effective way to foster communication variables. (shrink)

This paper analyses a hitherto unknown technique of using logic diagrams to create argument maps in eristic dialectics. The method was invented in the 1810s and -20s by Arthur Schopenhauer, who is considered the originator of modern eristic. This technique of Schopenhauer could be interesting for several branches of research in the field of argumentation: Firstly, for the field of argument mapping, since here a hitherto unknown diagrammatic technique is shown in order to visualise possible situations of arguments in a (...) dialogical controversy. Secondly, the art of controversy or eristic, since the diagrams do not analyse the truth of judgements and the validity of inferences, but the persuasiveness of arguments in a dialogue. (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)

Being able to discriminate poorly justified from well justified arguments is necessary for informed citizenship. However, it is not known whether the ability to recognize argument strength generalizes across different types of arguments, and what cognitive factors predict this ability or these abilities. Drawing on the theory of argument schemes, we examined arguments from consequence, analogy, symptoms, and authority in order to cover all major types of arguments. A study (N = 278) on the general population in Finland indicated that (...) the ability to discriminate between strong and weak arguments did not differ between these schemes. Argument strength discrimination ability correlated positively with analytic thinking dispositions promoting both quality and quantity of thinking, slightly positively with education, and negatively with overconfidence. It was unrelated to an intuitive thinking style, and to self-rated mental effort. (shrink)
