In any field, we might expect different features relevant to its understanding and development to receive attention at different times, depending on the stage of that field’s growth and the interests that occupy theorists and even the history of the theorists themselves. In the relatively young life of argumentation theory, at least as it has formed a body of issues with identified research questions, attention has almost naturally been focused on the central concern of the field—arguments. Focus is also (...) given to the nature of arguers and the position of the evaluator, who is often seen as possessing a “God’s-eye view” (Hamblin 1970). Less attention, however, has been paid in the philosophical literature to the .. (shrink)

The purpose of the paper is to draw attention to a kind of rational persuasion which has received little attention in argument studies even though its existence is acknowledged in other fields. I start with a brief analysis of the debates conducted in the comments on a philosophical blog. The posts are addressed to a non-academic audience, always end with a problem, and the reader is invited to offer a solution. In the comments we hardly ever find arguments in the (...) usual sense, i.e. in the sense that an argument consists of a set of premises providing justification for a conclusion. It is not that the arguments are laid out carelessly and require a good deal of reconstruction: typically, there is no argument to reconstruct. The author simply states his view, then goes on to sketch a larger picture of which his view is a part. In the responses to the comments we find the same: identification of the point of disagreement, no argument, elaboration of the preferred view in some detail. One might say that this is just a failure of rational discussion; in pragmadialectical terms, the discussion gets stuck in the opening stage. But there is another way of looking at the matter. Since the participants do not have sufficiently rich common background knowledge to take premises from, they cannot offer arguments proper and must resort to a different sort of rational persuasion. They try to show that their view can be extended into a larger, coherent picture. This makes good sense from an epistemological point of view. If a view is false, in trying to work out its details we sooner or later run into problems, so allowing coherent elaboration provides some degree of justification. One might say that the participants argue in the broad sense of trying to persuade by rational means, but they do that without adducing arguments proper. The claim that there is a way of rational persuasion which does not proceed by arguments proper can be further substantiated by noting that there debates whose status as rational discussion, as opposed to the comments on the philosophical blog, is not controversial. In discussing the work of some outstanding contemporary philosophers Gary Gutting argues that even though they do offer arguments, it is not by their arguments that they have convinced others of the viability of their approach, but by what he calls „persuasive elaboration”. We may also think of Kuhn’s account of the debates surrounding changes in paradigms: the arguments fail to persuade because their premises are not shared, but showing that the new paradigm can be extended to a vast variety of phenomena eventually succeeds. I finish by listing some questions this kind of rational persuasion may raise for argument studies. (shrink)

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

Introduction: Clinical practice guidelines (CPGs) are an important source of justification for clinical decisions in modern evidence-based practice. Yet, we have given little attention to how they argue their evidence. In particular, how do CPGs argue for treatment with long-term medications that are increasingly prescribed to older patients? Approach and rationale: I selected six disease-specific guidelines recommending treatment with five of the medication classes most commonly prescribed for seniors in Ontario, Canada. I considered the stated aims of these CPGs and (...) the techniques employed towards those aims. Finally, I reconstructed and logically analysed the arguments supporting recommendations for pharmacotherapy. Analysis: The primary function of CPGs is rhetorical, or persuasive, and their means of persuasion include both a display of their credibility and their argumentation. Arguments supporting pharmacotherapy recommendations for the target population follow a common inductive pattern: statistical generalization from randomized controlled trial (RCT) and meta-analysis evidence. Two of the CPGs also argue their treatment recommendations for older patients in this style, while three fail to justify pharmacotherapy specifically for the older population. Discussion: The arguments analysed lack the auxiliary assumptions that would warrant making a generalization about the clinical effectiveness of medications for the older population. Guidelines reason using simple induction, while ignoring important inferential gaps. Future guidelines should aspire to be well-reasoned rather than simply evidence-based; argue from a plurality of evidence; be wary of hasty inductions; appropriately limit the scope of their recommendations; and avoid making law-like, prescriptive generalizations.

In abstract argumentation, each argument is regarded as atomic. There is no internal structure to an argument. Also, there is no specification of what is an argument or an attack. They are assumed to be given. This abstract perspective provides many advantages for studying the nature of argumentation, but it does not cover all our needs for understanding argumentation or for building tools for supporting or undertaking argumentation. If we want a more detailed formalization of arguments (...) than is available with abstract argumentation, we can turn to structured argumentation, which is the topic of this special issue of Argument and Computation. In structured argumentation, we assume a formal language for representing knowledge and specifying how arguments and counterarguments can be constructed from that knowledge. An argument is then said to be structured in the sense that normally, the premises and claim of the argument are made explicit, and the relationship between the premises and claim is formally defined (for instance, using logical entailment). In this introduction, we provide a brief overview of the approaches covered in this special issue on structured argumentation. (shrink)

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.

Feminists note an association of arguing with aggression and masculinity and question the necessity of this connection. Arguing also seems to some to identify a central method of philosophical reasoning, and gendered assumptions and standards would pose problems for the discipline. Can feminine modes of reasoning provide an alternative or supplement? Can overarching epistemological standards account for the benefits of different approaches to arguing? These are some of the prospects for argumentation inside and outside of philosophy that feminists consider. (...) -/- The further concern is that the academic study of argumentation – in philosophy and other disciplines – has failed to account for the type of reasoning needed for social justice movements. What resources for addressing these concerns can be found in informal logic and interdisciplinary argumentation theory? Since part of the perceived problem derives from assuming that arguing is a contest, are more collaborative epistemological frameworks better? Can regular politeness or civility hedge against undesirable tendencies of argumentation? Can “critical thinking” pedagogy involving argument educations answer the needs of social justice? (shrink)

In this article, I present a new interpretation of the pro-life view on the status of early human embryos. In my understanding, this position is based not on presumptions about the ontological status of embryos and their developmental capabilities but on the specific criteria of rational decisions under uncertainty and on a cautious response to the ambiguous status of embryos. This view, which uses the decision theory model of moral reasoning, promises to reconcile the uncertainty about the ontological status of (...) embryos with the certainty about normative obligations. I will demonstrate that my interpretation of the pro-life view, although seeming to be stronger than the standard one, has limited scope and cannot be used to limit destructive research on human embryos.

The relationship between teaching and argumentation is becoming a crucial issue in the field of education and, in particular, science education. Teaching has been analyzed as a dialogue aimed at persuading the interlocutors, introducing a conceptual change that needs to be grounded on the audience’s background knowledge. This paper addresses this issue from a perspective of argumentation studies. Our claim is that argumentation schemes, namely abstract patterns of argument, can be an instrument for reconstructing the tacit premises (...) in students’ argumentative reasoning and retrieving the background beliefs that are the basis of their arguments. On this perspective, the process of premise reconstruction is followed by a heuristic reasoning process aimed at discovering the students’ previous intuitions that can explain the premises and concepts that are left unexpressed in their arguments. The theoretical insights advanced in this paper are illustrated through selected examples taken from activities concerning predictive claims on scientific issues. (shrink)

This thesis justifies the need for and develops a new integrated model of practical reasoning and argumentation. After framing the work in terms of what is reasonable rather than what is rational (chapter 1), I apply the model for practical argumentation analysis and evaluation provided by Fairclough and Fairclough (2012) to a paradigm case of unreasonable individual practical argumentation provided by mass murderer Anders Behring Breivik (chapter 2). The application shows that by following the model, Breivik is (...) relatively easily able to conclude that his reasoning to mass murder is reasonable – which is understood to be an unacceptable result. Causes for the model to allow such a conclusion are identified as conceptual confusions ingrained in the model, a tension in how values function within the model, and a lack of creativity from Breivik. Distinguishing between dialectical and dialogical, reasoning and argumentation, for individual and multiple participants, chapter 3 addresses these conceptual confusions and helps lay the foundation for the design of a new integrated model for practical reasoning and argumentation (chapter 4). After laying out the theoretical aspects of the new model, it is then used to re-test Breivik’s reasoning in light of a developed discussion regarding the motivation for the new place and role of moral considerations (chapter 5). The application of the new model shows ways that Breivik could have been able to conclude that his practical argumentation was unreasonable and is thus argued to have improved upon the Fairclough and Fairclough model. It is acknowledged, however, that since the model cannot guarantee a reasonable conclusion, improving the critical creative capacity of the individual using it is also of paramount importance (chapter 6). The thesis concludes by discussing the contemporary importance of improving practical reasoning and by pointing to areas for further research (chapter 7). (shrink)

This essay argues that ideals of cooperation or adversariality in argumentation are not equally attainable for women. Women in argumentation contexts face oppressive limitations undermining argument success because their authority is undermined by gendered norms of politeness. Women endorsing or, alternatively, transgressing feminine norms of politeness typically defend their authority in argumentation contexts. And yet, defending authority renders it less legitimate. My argument focuses on women in philosophy but bears the implication that other masculine dis- course contexts (...) present similar double binds that urge social and political change. (shrink)

We argue that common knowledge, of the kind used in reasoning in law and computing is best analyzed using a dialogue model of argumentation (Walton & Krabbe 1995). In this model, implicit premises resting on common knowledge are analyzed as endoxa or widely accepted opinions and generalizations (Tardini 2005). We argue that, in this sense, common knowledge is not really knowledge of the kind represent by belief and/or knowledge of the epistemic kind studied in current epistemology. This paper takes (...) a different approach, defining it in relation to a common commitment store of two participants in a rule-governed dialogue in which two parties engage in rational argumentation (Jackson & Jacobs 1980; van Eemeren & Grootendorst 2004). A theme of the paper is how arguments containing common knowledge premises can be studied with the help of argumentation schemes for arguments from generally accepted opinion and expert opinion. It is argued that common knowledge is a species of provi- sional acceptance of a premise that is not in dispute at a given point in a dia- logue, but may later be defeated as the discussion proceeds .

Building upon the role values take in Walton’s theory of practical reasoning, this paper will frame the question of how values should be evaluated into the broader question of what reasonable practical argumentation is. The thesis argued for is that if a positive evaluation of practical reasoning argumentation requires that the argument avoid a morally negative conclusion, then the role of values should be given a central, rather than supportive, position in practical argument evaluation.

The paper considers contemporary models of presumption in terms of their ability to contribute to a working theory of presumption for argumentation. Beginning with the Whatelian model, we consider its contemporary developments and alternatives, as proposed by Sidgwick, Kauffeld, Cronkhite, Rescher, Walton, Freeman, Ullmann-Margalit, and Hansen. Based on these accounts, we present a picture of presumptions characterized by their nature, function, foundation and force. On our account, presumption is a modal status that is attached to a claim and has (...) the effect of shifting, in a dialogue, a burden of proof set at a local level. Presumptions can be analysed and evaluated inferentially as components of rule-based structures. Presumptions are defeasible, and the force of a presumption is a function of its normative foundation. This picture seeks to provide a framework to guide the development of specific theories of presumption. (shrink)

The aim of the paper is to develop general criteria of argumentative validity and adequacy for probabilistic arguments on the basis of the epistemological approach to argumentation. In this approach, as in most other approaches to argumentation, proabilistic arguments have been neglected somewhat. Nonetheless, criteria for several special types of probabilistic arguments have been developed, in particular by Richard Feldman and Christoph Lumer. In the first part (sects. 2-5) the epistemological basis of probabilistic arguments is discussed. With regard (...) to the philosophical interpretation of probabilities a new subjectivist, epistemic interpretation is proposed, which identifies probabilities with tendencies of evidence (sect. 2). After drawing the conclusions of this interpretation with respect to the syntactic features of the probability concept, e.g. one variable referring to the data base (sect. 3), the justification of basic probabilities (priors) by judgements of relative frequency (sect. 4) and the justification of derivative probabilities by means of the probability calculus are explained (sect. 5). The core of the paper is the definition of '(argumentatively) valid derivative probabilistic arguments', which provides exact conditions for epistemically good probabilistic arguments, together with conditions for the adequate use of such arguments for the aim of rationally convincing an addressee (sect. 6). Finally, some measures for improving the applicability of probabilistic reasoning are proposed (sect. 7). (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)

The Pyrrhonist’s argumentative practice is characterized by at least four features. First, he makes a therapeutic use of arguments: he employs arguments that differ in their persuasiveness in order to cure his dogmatic patients of the distinct degrees of conceit and rashness that afflict them. Secondly, his arguments are for the most part dialectical: when offering an argument to oppose it to another argument advanced by a given dogmatist, he accepts in propria persona neither the truth of its premises and (...) conclusion nor the validity of its logical form. Thirdly, he avails himself of arguments in his own open-minded inquiry into the truth about a wide range of topics. Fourthly, Pyrrhonian argumentation is oppositional inasmuch as it typically works by producing oppositions among arguments that appear to the Pyrrhonist to be equipollent. In this article, I focus on the first three features with the aim of both shedding some light on them and determining whether they are in tension or coherently relate to each other. (shrink)

Defeasible argumentation has been applied successfully in several real-world domains in which it is necessary to handle incomplete and contradictory information. In recent years, there have been interesting attempts to carry out argumentation processes supported by massive repositories developing argumentative reasoning applications. One of such efforts builds arguments by retrieving information from relational databases using the DBI-DeLP framework; this article presents eDBI-DeLP, which extends the original DBI-DeLP framework by providing two novel aspects which refine the interaction between DeLP (...) programs and relational databases. First, we expand the expressiveness of dbi-delp programs by providing ways of controlling how the information in databases is recovered; this is done by introducing filters that enable an improved fine-grained control on the argumentation processes which become useful in applications, providing the semantics and the implementation of such filters. Second, we introduce an argument comparison criterion which can be adjusted at the level of literals to model particular features such as credibility and topic expertise, among others. These new tools can be particularly useful in environments such as medical diagnosis expert systems, decision support systems, or recommender systems based on argumentation, where datasets are often provided in the form of relational databases.

While anger can derail argumentation, it can also help arguers and audiences to reason together in argumentation. Anger can provide information about premises, biases, goals, discussants, and depth of disagreement that people might otherwise fail to recognize or prematurely dismiss. Anger can also enhance the salience of certain premises and underscore the importance of related inferences. For these reasons, we claim that anger can serve as an epistemic resource in argumentation.

Virtue theories have lately enjoyed a modest vogue in the study of argumentation, echoing the success of more far-reaching programmes in ethics and epistemology. Virtue theories of argumentation (VTA) comprise several conceptually distinct projects, including the provision of normative foundations for argument evaluation and a renewed focus on the character of good arguers. Perhaps the boldest of these is the pursuit of the fully satisfying argument, the argument that contributes to human flourishing. This project has an independently developed (...) epistemic analogue: eudaimonistic virtue epistemology. Both projects stress the importance of widening the range of cognitive goals beyond, respectively, cogency and knowledge; both projects emphasize social factors, the right sort of community being indispensable for the cultivation of the intellectual virtues necessary to each project. This paper proposes a unification of the two projects by arguing that the intellectual good life sought by eudaimonistic virtue epistemologists is best realized through the articulation of an account of argumentation that contributes to human flourishing.

In this article author traces relation between argumentation and cultural practice. The first part focuses on definition of argumentation in informal logic tradition. In particular, it discusses argument in terms of verbal and social activity involving the use of everyday language. Author claims that there is no argumentation beyond language. The second part explains persuasive argumentation as a form of cultural practice. The persuasive arguments found in “social practice” can be understood as a social activity, analysable (...) within the context of a given cultural system. Author refers to an approach taking the argumentative expression as a certain type of communicative practice, directed towards respecting, recognising or accepting specific actions. The inclusion of persuasive argumentation in the “circuit of cultural activities” to be studied makes it possible to compare this type of argumentation with other social practices, and to posit a clear historical dimension in the study of argumentation. It also makes it possible to view persuasive argumentation as one of many cultural activities aimed at changing or perpetuating behaviours, attitudes, thinking, etc. The third part of the paper concerns the problem of humanistic interpretation of persuasive argumentation. Author attempts to develop this intuition, at the same time demonstrating the problems that arise from this approach. In conclusion, author tries to analyze argumentation in terms of culture theory and humanistic interpretation. (shrink)

In her 2007 paper, “Argument Has No Function” Jean Goodwin takes exception with what she calls the “explicit function claims”, arguing that not only are function-based accounts of argumentation insufficiently motivated, but they fail to ground claims to normativity. In this paper I stake out the beginnings of a functionalist answer to Goodwin.

Rozprawa podkreśla związek między językową argumentacją a logiką. Argumentacja językowa jest systemem językowym, który stosuje znaczenie wyrażeń ujętych w zdania do zarysowania pełnego znaczenia zdań, w nich bowiem konstytuują się zależności między wyrażeniami. Rzeczywiście, to powiązanie między wyrażeniami wzmacnia całościowe znaczenie począwszy od samych podstaw struktury zdania w logicznym powiązaniu idei. W nim znajduje się relacja między słowami a umysłem, zależna od logiki powiązanych ze sobą wypowiedzi. Aby podkreślić znaczenie przedstawionego wyżej sposobu myślenia, autorka zwraca się ku teorii wczesnej gramatyki (...) arabskiej, ogniskującej się raczej wokół analogii niż anomalii. Nastawienie w systemie na analogię opiera się na podstawowej teorii, która implikuje wspomnianą wyżej relację, choć niektóre współczesne ujęcia odrzucają tę interpretację. W podsumowaniu swojej analizy, autorka uwzględnia podobne teorie gramatyki łacińskiej, które wykazują nastawienie logiczne, będące następstwem powiązania językowej argumentacji z logiką. Konkludując, autorka stwierdza, iż powiązanie słów i logiki okazuje się pojęciem uniwersalnym. (shrink)

This article analyses letters to the editor written on or about Muslims printed in a British broadsheet newspaper. The pragma-dialectical theory of argumentation is applied as a model for explaining and understanding the arguments employed in the sampled letters. Our presentation of pragma-dialectical theory focuses on argumentative reasonableness. More specifically, we introduce the four dialectical stages through which any argument must pass and explain the ten rules of critical discussion that participants must follow throughout if they are to resolve (...) the argument. The article focuses in particular on the letter writers' use of argument schemes-that is, the manner in which these writers use arguments to support their standpoints. We conclude by highlighting the role that unreasonable arguments can play in perpetuating racialized inequalities and hence the importance of analyzing argumentation. (shrink)

In this paper we use a series of examples to show how oppositions and dichotomies are fundamental in legal argumentation, and vitally important to be aware of, because of their twofold nature. On the one hand, they are argument structures underlying various kinds of rational argumentation commonly used in law as a means of getting to the truth in a conflict of opinion under critical discussion by two opposing sides before a tryer of fact. On the other hand, (...) they are argument structures underling moves made in strategic advocacy by both sides that function as platforms for different kinds of questionable argumentation tactics and moves that are in some instances tricky and deceptive.

The issue of whether or not there are visual arguments has been an issue in informal logic and argumentation theory at least since 1996. In recent years, books, sections of prominent conferences and special journals issues have been devoted to it, thus significantly raising the profile of the debate. In this paper I will attempt to show how the views of the later Wittgenstein, particularly his views on images and the no- tion of “picturing”, can be brought to bear (...) on the question of whether there are such things as “purely visual” arguments. I shall draw on Wittgenstein’s remarks in the Blue and Brown Books and in Philosophical Investigations in order to argue that al- though visual images may occur as elements of argumentation, broadly conceived, it is a mistake to think that there are purely visual arguments, in the sense of illative moves from premises to conclusions that are conveyed by images alone, without the support or framing of words.

In this chapter I argue that intellectual humility is related to argumentation in several distinct but mutually supporting ways. I begin by drawing connections between humility and two topics of long-standing importance to the evaluation of informal arguments: the ad verecundiam fallacy and the principle of charity. I then explore the more explicit role that humility plays in recent work on critical thinking dispositions, deliberative virtues, and virtue theories of argumentation.

Ethotic arguments are defined as sequences of claims-and-reasons regarding speaker character, based on which the plausibility of speaker assertions can be questioned. This is an exploratory study concerning the role of visuals in ethotic arguing. In this paper, I bring together contributions from visual argumentation theory and from studies regarding various modes of construing an ethotic argument, in an attempt to offer an adequate account of the argumentative action of images in ethotic sequences of discourse. In the last section, (...) I propose a case study which illustrates the argumentative action that visuals may perform in the ethotic genre of advertising. (shrink)

Aristotle determines eristic argument as argument which either operates upon the basis of acceptable premisses (endoxa) and merely give the impression of being deductive, or argument which truly is deductive but operates upon the basis of premisses which seem to be acceptable, but are not (or, again, argument which uses both of these mechanisms). I attempt to understand what Aristotle has in mind when he says that someone is deceived into accepting premisses which seem to be acceptable but which are (...) really not, and how this disqualifies such arguments from being dialectical. In the first section of the paper I interpret Aristotle’s notion of endoxa in terms of a relational concept of acceptability. Real Índoxa are propositions which are accepted by a qualified group or individual. False endoxa may also be accepted by someone or some group, and may even be true, but they are used to serve the purposes of eristical argumentation, which departs from certain standards of dialectical argumentation articulated in the notion of endoxa as a norm for premiss-acceptance. In particular, eristic arguments may even be valid in the sense of a syllogismos while still failing to be proper dialectical arguments. In the second part of the paper I consider how this can be, in examining certain types of fallacies in the Sophistical Refutations and the relationship between fallacious argumentation and false endoxa.

The well-known empiricist apories of the lawfulness of nature prevent an adequate philosophical interpretation of empirical science until this day. Clarification can only be expected through an immanent refutation of the empiricist point of view. My argument is that Hume’s claim, paradigmatic for modern empiricism, is not just inconsequent, but simply contradictory: Empiricism denies that a lawlike character of nature can be substantiated. But, as is shown, anyone who claimes experience to be the basis of knowledge (as the empiricist naturally (...) does), has, in fact, always already presupposed the lawfullness of nature, i.e. has assumed the ontology of a nature lawful in itself. If lawfulness is, more closely, understood as dependency on conditions, then the functional character of the laws of nature is involved with the consequence that verification is not to be taken as a mere repetition of measurements but as clarification of the conditional structure of the physical process. Furthermore the functionality of the laws of nature also includes a statement on their invariance (relative to certain transformations) and so their lawlikeness. This throws a new light on the problem of induction. Seen in this way it is hardly surprising that the notorious neglect of the functional aspect in empiricism has led to fundamental problems with the concept of the law of nature. (shrink)

José Ángel Gascón’s essay "Where are dissent and reasons in epistemic justification?" is an exposition of a version of a social functionalist epistemology. I agree with Gascón's emphasis on reasons and on taking into account dissent as important parts of epistemology. But I think that these concerns do not require a social functionalist epistemology, but that, on the contrary, Gascón's social functionalist epistemology throws the baby out with the bathwater. It does so by excluding also a traditional, at its core (...) individualistic epistemology, which defines central concepts like 'justified', 'knowledge' still in individualistic terms as the result of a mental cognizing process but is open to social extensions, e.g. concerning cooperation in the acquisition of knowledge or the transfer of knowledge via argumentation. Such a socially open epistemology with an individualistic core – or "open individualistic epistemology" for short – is also the basis of the epistemological argumentation theory. In the following I want to explain and defend this open individualistic epistemology together with the epistemological argumentation theory (sect. 2) and explain on this basis some problems of Gascón’s theory (sect. 3).

This dissertation is an analysis of the development of dialectic and argumentation theory in post-classical Islamic intellectual history. The central concerns of the thesis are; treatises on the theoretical understanding of the concept of dialectic and argumentation theory, and how, in practice, the concept of dialectic, as expressed in the Greek classical tradition, was received and used by five communities in the Islamic intellectual camp. It shows how dialectic as an argumentative discourse diffused into five communities (theologicians, poets, (...) grammarians, philosophers and jurists) and how these local dialectics that the individual communities developed fused into a single system to form a general argumentation theory (adab al-bahth) applicable to all fields. I evaluate a treatise by Shams al-Din Samarqandi (d.702/1302), the founder of this general theory, and the treatises that were written after him as a result of his work. I concentrate specifically on work by 'Ad}ud al-Din al-Iji (d.756/1355), Sayyid Sharif al-Jurjani (d.816/1413), Taşköprüzâde (d.968/1561), Saçaklızâde (d.1150/1737) and Gelenbevî (d.1205/1791) and analyze how each writer (from Samarqandi to Gelenbevî) altered the shape of argumentative discourse and how later intellectuals in the post-classical Islamic world responded to that discourse bequeathed by their predecessors. What is striking about the period that this dissertation investigates (from 1300-1800) is the persistence of what could be called the linguistic turn in argumentation theory. After a centuries-long run, the jadal-based dialectic of the classical period was displaced by a new argumentation theory, which was dominantly linguistic in character. This linguistic turn in argumentation dates from the final quarter of the fourteenth century in Iji's impressively prescient work on 'ilm al-wad'. This idea, which finally surfaced in the post-classical period, that argumentation is about definition and that, therefore, defining is the business of language—even perhaps, that language is the only available medium for understanding and being understood—affected the way that argumentation theory was processed throughout most of the period in question.The argumentative discourse that started with Ibn al-Rawandi in the third/ninth century left a permanent imprint on Islamic intellectual history, which was then full of concepts, terminology and objectives from this discourse up until the late nineteenth century. From this perspective, Islamic intellectual history can be read as the tension between two languages: the "language of dialectic" (jadal) and the "language of demonstration" (burhan), each of which refer not only to a significant feature of that history, but also to a feature that could dramatically alter the interpretation of that history.

One of the central tasks of a theory of argumentation is to supply a theory of appraisal: a set of standards and norms according to which argumentation, and the reasoning involved in it, is properly evaluated. In their most general form, these can be understood as rational norms, where the core idea of rationality is that we rightly respond to reasons by according the credence we attach to our doxastic and conversational commitments with the probative strength of the (...) reasons we have for them. Certain kinds of rational failings are so because they are manifestly illogical – for example, maintaining overtly contradictory commitments, violating deductive closure by refusing to accept the logical consequences of one’s present commitments, or failing to track basing relations by not updating one’s commitments in view of new, defeating information. Yet, according to the internal and empirical critiques, logic and probability theory fail to supply a fit set of norms for human reasoning and argument. Particularly, theories of bounded rationality have put pressure on argumentation theory to lower the normative standards of rationality for reasoners and arguers on the grounds that we are bounded, finite, and fallible agents incapable of meeting idealized standards. This paper explores the idea that argumentation, as a set of practices, together with the procedures and technologies of argumentation theory, is able to extend cognition such that we are better able to meet these idealized logical standards, thereby extending our responsibilities to adhere to idealized rational norms.

This paper examines the cognitive foundations of natural theology: the intuitions that provide the raw materials for religious arguments, and the social context in which they are defended or challenged. We show that the premises on which natural theological arguments are based rely on intuitions that emerge early in development, and that underlie our expectations for everyday situations, e.g., about how causation works, or how design is recognized. In spite of the universality of these intuitions, the cogency of natural theological (...) arguments remains a matter of continued debate. To understand why they are controversial, we draw on social theories of reasoning and argumentation. (shrink)

The paper critically discusses an empirical study by Mizrahi & Dickinson 2020, which analyzes in a huge data base (JSTORE) the incidence of three types of philosophical arguments. Their results are: 1. Deductive arguments were the most commeon type of argument in philosophy until the end of the 20th century. 2. Around 2008 a shift in methodology occurred, such that the indcutive arguments outweigh other types of argument.

We are pleased to publish this WSIA edition of Trudy’s Govier’s seminal volume, Problems in Argument Analysis and Evaluation. Originally published in 1987 by Foris Publications, this was a pioneering work that played a major role in establishing argumentation theory as a discipline. Today, it is as relevant to the field as when it first appeared, with discussions of questions and issues that remain central to the study of argument. It has defined the main approaches to many of those (...) issues and guided the ways in which we might respond to them. From this foundation, it sets the stage for further investigations and emerging research. This is a second edition of the book that is corrected and updated by the author, with new prefaces to each chapter. (shrink)

Das spezifische Ziel von Argumentationen ist nicht einfach, den Adressaten etwas glauben zu machen - dies wäre bloße Rhetorik ﷓, sondern: den Adressaten beim Erkennen der Akzeptabilität (insbesondere der Wahrheit) der These anzuleiten und ihn so zu begründetem Glauben, zu Erkenntnis zu führen. Argumentationen leiten das Erkennen an, indem sie in ihren Argumenten hinreichende Akzeptabilitätsbedingungen der These als erfüllt beurteilen und so den Adressaten implizit auffordern, diese Bedingungen zu überprüfen. Argumentationen sind gültig, wenn sie prinzipiell das Erkennen anleiten können; d. (...) h. wenn die genannten Akzeptabilitätsbedingungen hinreichend sind, wenn sie tatsächlich erfüllt (die Argumente also wahr) sind und wenn es irgendjemanden gibt, der zwar die Akzeptabilität der Argumente, nicht aber die der These erkannt hat. Eine gültige Argumentation ist adäquat, um einen bestimmten Adressaten rational zu überzeugen, wenn dieser u. a. die Akzeptabilität der Argumente, nicht aber die der These erkannt hat. Die in gültigen Argumentationen als erfüllt beurteilten Akzeptabilitätsbedingungen sind Konkretisierungen allgemeiner Erkenntnisprinzipien für die spezifische These, z. B. des deduktiven Erkenntnisprinzips: 'Eine Proposition ist wahr, wenn sie von wahren Propositionen logisch impliziert wird.' oder des erkenntnisgenetischen Erkenntnisprinzips: 'Eine Proposition ist wahr, wenn sie korrekt verifiziert worden ist.' Eine Konkretisierung des deduktiven Prinzips für eine These p wäre z. B.: 'p ist wahr, 1. wenn q und r wahr sind und 2. wenn q und r zusammen p logisch implizieren.' Sind beide Bedingungen erfüllt, so könnte 'q; r; also p.' eine gültige deduktive Argumentation sein. Die verschiedenen Argumentationstypen unterscheiden sich danach, auf welchem Erkenntnisprinzip sie basieren. Das argumentativ angeleitete Erkennen der Akzeptabilität der These funktioniert so: Der Adressat benutzt das von ihm (zumindest implizit) gewußte allgemeine Erkenntnisprinzip als Checkliste, auf der er nach dem Vorbringen der Argumente abhakt, welche Akzeptabilitätsbedingung des Erkenntnisprinzips durch das Zutreffen des Arguments jeweils erfüllt wird. Auf der Basis dieser Funktionsbestimmung werden in der "Praktischen Argumentationstheorie" (erstmalig) präzise Gültigkeitskriterien für Argumentationen allgemein und für mehrere spezielle Argumentationstypen entwickelt, erkenntnistheoretisch begründet und auf komplexe Argumentationsbeispiele aus Philosophie, Wissenschaft, Technik und Kultur angewendet. Die Analyse der erkenntnistheoretischen Grundlagen - der zugrundeliegenden Erkenntnisprinzipien - vor allem der interpretierenden und praktischen Argumentationen ist zudem von erheblicher Bedeutung weit über die Argumentationstheorie hinaus: für die Interpretationstheorie, die Handlungstheorie und die praktische Philosophie.

Argument from analogy is a common and formidable form of reasoning in law and in everyday conversation. Although there is substantial literature on the subject, according to a recent survey ( Juthe 2005) there is little fundamental agreement on what form the argument should take, or on how it should be evaluated. Th e lack of conformity, no doubt, stems from the complexity and multiplicity of forms taken by arguments that fall under the umbrella of analogical reasoning in argumentation, (...) dialectical studies, and law. Modeling arguments with argumentation schemes has proven useful in attempts to refine the analyst’s understanding of not only the logical structures that shape the backbone of the argument itself, but also the logical underpinning of strategies for evaluating it, strategies based on the semantic categories of genus and relevance. By clarifying the distinction between argument from example and argument from analogy, it is possible to advance a useful proposal for the treatment of argument from analogy in law. (shrink)

Mit großer Wahrscheinlichkeit wird die Alternative für Deutschland (AfD) am 24. September in den Bundestag einziehen. Jüngste Umfragen legen nahe, dass sie sogar drittstärkste Partei werden könnte. Warum findet die AfD so viele Unterstützerinnen und Unterstützer? Mit welchen Argumenten wirbt die AfD für ihren Einzug in den Bundestag? Das Wahlprogramm der AfD zeigt nicht nur, wofür die Partei steht, sondern auch welche Strategie sie bei der Bundestagswahl und darüber hinaus verfolgt. Aus diesem Grund habe ich es argumentationstheoretisch analysiert und die (...) darin enthaltene Argumentation im Detail rekonstruiert. Die wichtigsten Ergebnisse umfassen: Erstens, aus einer rein logischen Perspektive ist die Argumentation der AfD außergewöhnlich klar und stringent. Dies gelingt ihr deshalb, weil sie sich gezielt auf Annahmen stützt, die vereinfachend oder konstruiert sind. Zweitens, das zentrale Thema der „Flüchtlingskrise“ zieht sich beinahe durch die gesamte Argumentation. Es taucht in Argumenten über den Verlust der Leitkultur oder den Verfall der inneren Sicherheit genauso auf wie in Argumenten über die Folgen der Globalisierung oder den demographischen Wandel. Drittens, und dies ist das zentrale Ergebnis der Analyse, die AfD argumentiert nach dem folgenden Muster: Es gibt eine Bedrohung. Nur die AfD kann uns davor bewahren. Also muss die AfD an die Macht kommen. Dies nenne ich das „Kernargument des Populismus“. (shrink)

The aim of the paper is to present a typology of argument schemes. In first place, we found it helpful to define what an argument scheme is. Since many argument schemes found in contemporary theories stem from the ancient tradition, we took in consideration classical and medieval dialectical studies and their relation with argumentation theory. This overview on the main works on topics and schemes provides a summary of the main principles of classification. In the second section, Walton’s theory (...) is briefly explained to introduce the schemes classification and its different levels. At least, the final part shows the main application of the schemes in computing and AI. -/- . (shrink)

In this paper, I argue that, just as the problem of unconceived alternatives provides a basis for a New Induction on the History of Science to the effect that a realist view of science is unwarranted, the problem of unconceived objections provides a basis for a New Induction on the History of Philosophy to the effect that a realist view of philosophy is unwarranted. I raise this problem not only for skepticism’s sake but also for the sake of making a (...) point about philosophical argumentation, namely, that anticipating objections to one’s claim is not the same as supporting one’s claim. In other words, defending p from objections does not amount to support or evidence for p. This, in turn, presents dialectical and pragma-dialectical approaches to argumentation with the following question: does proper argumentation require that arguers anticipate and respond to unconceived objections?

One innovation in this paper is its identification, analysis, and description of a troubling ambiguity in the word ‘argument’. In one sense ‘argument’ denotes a premise-conclusion argument: a two-part system composed of a set of sentences—the premises—and a single sentence—the conclusion. In another sense it denotes a premise-conclusion-mediation argument—later called an argumentation: a three-part system composed of a set of sentences—the premises—a single sentence—the conclusion—and complex of sentences—the mediation. The latter is often intended to show that the conclusion follows (...) from the premises. The complementarity and interrelation of premise-conclusion arguments and premise-conclusion-mediation arguments resonate throughout the rest of the paper which articulates the conceptual structure found in logic from Aristotle to Tarski. This 1972 paper can be seen as anticipating Corcoran’s signature work: the more widely read 1989 paper, Argumentations and Logic, Argumentation 3, 17–43. MR91b:03006. The 1972 paper was translated into Portuguese. The 1989 paper was translated into Spanish, Portuguese, and Persian. (shrink)

There are emotively powerful words that can modify our judgment, arouse our emotions and influence our decisions. This paper shows how the use of emotive meaning in argumentation can be explained by showing how their logical dimension, which can be analysed using argumentation schemes, combines with heuristic processes triggered by emotions. Arguing with emotive words is shown to use value-based practical reasoning grounded on hierarchies of values and maxims of experience for evaluative classification.
