Coalescent argumentation is a normative ideal that involves the joining together of two disparate claims through recognition and exploration of opposing positions. By uncovering the crucial connection between a claim and the attitudes, beliefs, feelings, values and needs to which it is connected dispute partners are able to identify points of agreement and disagreement. These points can then be utilized to effect coalescence, a joining or merging of divergent positions, by forming the basis for a mutual investigation of non-conflictual options (...) that might otherwise have remained unconsidered. The essay proceeds by defining and discussing ‘argument’, ‘position’ and ‘understanding’. These notions are then brought together to outline the concept of coalescent reasoning. (shrink)

In chemistry one observes different relationships [rapports] between different bodies, which act such that they unite easily with one another. These relationships have their degrees and their laws. One observes their different insofar as, among several materials are confounded and that have some disposition to unite together, one perceives that one of these substances always unites constantly with a certain other [substance] preferably to all others.

In this analysis of the ethical dimensions of doctors’ participation in macroallocation we set out to understand the skills they use, how they are acquired, and how they influence performance of the role. Using the principles of grounded moral analysis, we conducted a semi-structured interview study with Australian doctors engaged in macroallocation. We found that they performed expertise as argument, bringing together phronetic and rhetorical skills founded on communication, strategic thinking, finance, and health data. They had made significant, purposeful efforts (...) to gain skills for the role. Our findings challenge common assumptions about doctors’ preferences in argumentation, and reveal an unexpected commitment to practical reason. Using the ethics of Paul Ricoeur in our analysis enabled us to identify the moral meaning of doctors’ skills and learning. We concluded that Ricoeur’s ethics offers an empirically grounded matrix for ethical analysis of the doctor’s role in macroallocation that may help to establish norms for procedure. (shrink)

For several millennia now, the enthymeme has been taught, on the putative authority of Aristotle, as "a kind of syllogism" —that is, a rhetorical syllogism—that consists in a three-part unit of deductive reasoning that parallels the inductive reasoning of the example. The rhetorical syllogism is said to be imperfect or incomplete because it relies on probable or particular rather than certain or universal premises and because the speaker suppresses one premise or the conclusion, usually the major premise, leaving it with (...) only two stated terms as follows:Socrates is a manSocrates is mortalOne premise is left unstated because it is known to the members of the audience (they...

We argue that Cohen’s concept of inductive or ampliative probability facilitates proper explication of sufficient strength for non-demonstrative arguments conforming to the Toulmin model. The data and claims of such arguments are singular statements. We may epistemically classify the warrants of such arguments as empirical (either physical or personal), institutional, or evaluative. Backing evidence and rebutting considerations vary with the epistemic type of warrant, but in each case the notion of ampliative probability for arguments with warrants of that type can (...) be characterized. We may then use ampliative probability to define sufficient strength and related notions for Toulmin arguments. (shrink)

ABSTRACT This essay tells the story of Perelman and Olbrechts-Tyteca's “dissociation of concepts,” which they introduced in 1958 and is in use as a tool of criticism by many rhetorical critics. The story begins in England with John Locke's development of associative reasoning in 1770 and then moves to France, with Remy de Gourmont extending associative reasoning with the concept of dissociation in 1899. Gourmont's dissociation crosses the Atlantic and is then developed by Kenneth Burke in 1931. In turn, Perelman (...) and Olbrechts-Tyteca absorbed and expanded Locke, Gourmont, and Burke's theories of association and dissociation in 1958. They crafted a tool, the dissociation of concepts, that equips rhetorical reasoning with the capacity to navigate between the promise and perils of fission and fusion. Since 1958, many scholars have made productive use of Perelman and Olbrechts-Tyteca's innovation. The essay concludes with some possible futures for their dissociation of concepts. (shrink)

Following a linguistic-descriptivist approach, Marianne Doury has studied debates about “parasciences”, discovering that “parascientists” frequently argue by “appeal to Galileo” ; opponents object by criticizing the analogy, charging fallacy, and appealing to counter-examples. I argue that Galilean appeals are much more widely used, by creationists, global-warming skeptics, advocates of “settled science”, great scientists, and great philosophers. Moreover, several subtypes should be distinguished; critiques questioning the analogy are proper; fallacy charges are problematic; and appeals to counter-examples are really indirect critiques of (...) the analogy.

ABSTRACT The sections devoted to dissociation in The New Rhetoric identify many verbal forms that can express this reconceptualizing line of argument. This article reviews the linguistic options offered in English for epitomizing dissociations, including tautologies and constructions that prompt diverging meanings, orthographical devices like capitalization or subscripts that produce variants of a single word, word schemes like agnominatio and polyptoton that alter core forms, and affixes or modifiers that are either available as antonyms or require forcing apart by subsequent (...) antitheses. Paying attention to the verbal expression of dissociations highlights cases that may or may not qualify as the rich reconceptualizations Perelman and Olbrechts-Tyteca had in mind. Arguments that involve three distinguished terms may, for example, reach a limit where dissociations merge into arguments from division, a long recognized device in traditional rhetoric/dialectic.

Public policy decisions often require rhetorically-engaged citizens to have some understanding of the science and technology involved. On many current issues sectors of the public hold views differing from those of most scientists, and they often do not support proposals based on the scientists’ views. The overall cultural authority of science has also been challenged in the last decade by several negative trends in the sciences themselves, including widely-reported cases of fraud and failures in replication. With the support of professional (...) science organizations, science communication specialists have stepped in aggressively to address science’s communication problems scientifically. This paper will examine the assumptions behind their advice on scientific information, their recommended strategies of framing, narration, and projecting trustworthiness, and their characterizations of audiences and the nature of science itself. From the perspective of rhetorical argumentation, the science communication literature does not promote addressing audiences as citizens capable of rational argumentation. But the science of science communication is likely to remain the dominant approach to public science with the professional science community. (shrink)

Archaeologists have long disagreed about when and how humans first migrated into the Americas; a point particularly in contention is whether there is any convincing evidence of human occupation earlier than about 12,000 years ago. This article ex amines some recent publications on the controversy, selected especially from review articles and from a recent series, written by professional archaeologists, that appeared in a popular magazine, Natural History. The sample texts are analyzed from a rhetorical perspective with emphasis on textual features (...) such as word choice, hedging, arrange ment, self-reference, argumentative topic, and figure. Such features are taken to be signs of the writer's accommodation to audience and situation as determined in part by the place of publication. The analysis reveals some of the rich variety of persuasive techniques employed in popular and review publications by scientists who find themselves in a disciplinary stalemate, for example, the attempt of each side to depict itself as in the minority. The well-crafied popular pieces also use explicit appeals left only im plicit in the review articles; for example, the popular pieces describe the writer's status based on years of experience and support conclusions by narrating the long process of inquiry followed before a verdict was reached.

In this paper a theoretical definition that helps to explain how the logical structure of legal presumptions is constructed by applying the Carneades model of argumentation developed in artificial intelligence. Using this model, it is shown how presumptions work as devices used in evidentiary reasoning in law in the event of a lack of evidence to assist a chain of reasoning to move forward to prove or disprove a claim. It is shown how presumptions work as practical devices that may (...) be useful in cases in which there is insufficient evidence to prove the claim to an appropriate standard of proof. (shrink)

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)

Metaphor has been considered as a cognitive process, independent of the verbal versus visual mode, through which an unknown conceptual domain is understood in terms of another known conceptual domain. Metaphor might instead be viewed as a cognitive process, dependent on the mode, which leads to genuinely new knowledge via ignorance. First, I argue that there are two main senses of ignorance at stake when we understand a metaphor: we ignore some existing properties of the known domain in the sense (...) that we disregard or neglect them; we ignore some “non-existing” properties of the known domain in the sense that they are not a piece of information belonging to the known domain, but emerge in metaphor interpretation. Secondly, I consider a metaphor as a reasoning device, guiding the interpreters along a path of inferences to a conclusion, which attributes to the target some properties of the source. In this path, interpreters might discover the ignored existing properties of the known domain and/or recover the “non-existing” properties, inferring or imagining the missing piece of information. Finally, I argue that, especially in visual metaphors, this process is guided by a “sentiment of rationality”, tracking a disruption of existing familiar conceptualisations of objects and/or actions and a recovery of ignored properties.

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 essay argues that Plato's “Gorgias,” a dialogue lauding dialectic over rhetoric, uses a question-and-answer format as a heuristic of argument. Specific observations are advanced to explain the implications of Plato's techniques and to provide a more sensitive understanding of the process by which sought to gain the adherence of his readers.

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

This volume presents a selection of papers reflecting key theoretical issues in argumentation theory. Its six sections are devoted to specific themes, including the analysis and evaluation of argumentation, argument schemes and the contextual embedding of argumentation. The section on general perspectives on argumentation discusses the trends of empiricalization, contextualization and formalization, offers descriptions of the analytical and evaluative tools of informal logic, and highlights selected principles that argumentation theorists do and do not agree upon. In turn, the section on (...) linguistic approaches to argumentation focuses on the problem of distinguishing between explanation and argument, while also elaborating on the role of verbal indicators of argument schemes. All essays included in this volume point out notable recent developments in the study of argumentation. (shrink)

The purpose of this treatise is to analyse five of the Copenhagen Climate Convention's main speeches to see how they supported or weakened the agreement possibilities in the convention. Particular focus will be on the elements that divide or unite negotiators and whether the summit's failing outcome is already built in the pre-planned speeches held at the main podium. Theoretically, the study builds on Kenneth Burke's identification thesis and Elizabeth L. Malone's climate change debate analysis. I combine these in my (...) analysis using a revised version of Malone's argument family classification tool putting it into Burke's theoretical framework. The central concept is Burke's identification, whose manifestations are searched from speeches. The analysis will cover five of the main speeches from Copenhagen summit negotiators (the United States, China, Zimbabwe, the African Union and the Climate Group). Analysed speeches contain more elements that divide negotiators than elements with possibly uniting effect. The division between North and South is particularly distinct in most speeches. Another dividing issue is the major emitters' tendency to speak themselves out of more emission cut commitments instead of expressing willingness to engage in more ambitious accord. At the same time, less developed countries utter their mistrust which increases division and weakens the possibilities for negotiators to become consubstantial. Every participator agrees in public about seriousness of climate change, but this claim is supported only weakly by other arguments in their speeches. Copenhagen Climate Convention's failure can be foreseen in speeches that fail to build and recognise a common interest among negotiator countries. Rhetorical analysis reveals that climate change as an environmental problem is not faced by a ”global we” but from national perspectives, which weakens the possibilities for real action. The ”global we” facing and reacting to climate change has not emerged. This is a challenge for further study discussing the ways in which the real identification could be achieved and action taken.

Статья посвящена выявлению оснований доксологии Матса Розенгрена – шведского философа, который пытается реабилитировать доксу в теории познания и рассматривает возможность построения «протагорейской гносеологии». Доксология – это вариант натурализованной конструктивистской теории познания, развивающийся на базе риторической версии философской антропологии, где формулируется реалистичная версия субъекта познавательной деятельности. Познание, с точки зрения доксологии, – это преобразование человеческими коллективами мира и себя, предпосылкой которого является освоение объективированных результатов своей предшествующей деятельности. В ходе исследования использованы методы интерпретации и критический метод философии с опорой на принципы (...) историзма, непротиворечивости и системности рассмотрения. Показано, что выражением доксологической позиции и доксологического стиля мышления является неософистическая трактовка тезиса Протагора о человекомерности. Согласно этой трактовке, человек – это человечество, а не индивид; мерой, общей для всех людей, является логос, который формирует природу человека и мира в целом. В основе доксологической трактовки познавательной деятельности лежит схема функционального круга логоса и доксы. Содержательные предпосылки доксологического стиля мышления Розенгрен находит в работах П. Бурдьё, Л. Флека, Э. Кассирера, К. Касториадиса, в которых продемонстрировано, как фактически способы восприятия, мышления и действия, и способы производства, объективации и освоения опыта человеческих коллективов могут взаимозависимо конструировать друг друга.

Woods and Walton deserve credit for including a discussion of “economic reasoning” and its susceptibility to the “fallacy of composition.” Unfortunately, they did not sufficiently pursue the topic, and argumentation scholars have apparently ignored their pioneering effort. Yet, obviously, economic argumentation is extremely important, and economists constantly harp on this fallacy. This paper calls attention to this problem, elaborating my own approach, which is empirical, historical, and meta-argumentational.

Despite the effort educators put into developing in students the critical writing and thinking skills needed to compose effective arguments, undergraduate college students are often accused of churning out essays lacking in creative and critical thought, arguments too obviously formulated and with sides too sharply drawn. Theories abound as to why these deficiencies are rampant. Some blame students’ immature cognitive and emotional development for these lacks. Others put the blame of lackadaisical output on the assigning of shopworn writing subjects, assigned (...) topics such as on American laws and attitudes about capital punishment and abortion. Although these factors might contribute to faulty written output in some cases, the prevailing hindrance is our very pedagogy, a system in which students are rewarded for composing the very type of argument we wish to avoid — the eristic, in which the goal is not truth seeking, but successfully disputing another’s argument. Certainly the eristic argument is the intended solution in cases when a clear‑cut outcome is needed, such as in legal battles and political campaigns when there can only be one winner. However, teaching mainly or exclusively the eristic, as is done in most composition classrooms today, halts the advancement of these higher‑order inquiry skills we try developing in our students.

We report on an exploratory study of the way eight mid-level undergraduate mathematics majors read and reflected on four student-generated arguments purported to be proofs of a single theorem. The results suggest that mid-level undergraduates tend to focus on surface features of such arguments and that their ability to determine whether arguments are proofs is very limited -- perhaps more so than either they or their instructors recognize. We begin by discussing arguments (purported proofs) regarded as texts and validations of (...) those arguments, i.e., reflections of individuals checking whether such arguments really are proofs of theorems. We relate the way the mathematics research community views proofs and their validations to ideas from reading comprehension and literary theory. We then give a detailed analysis of the four student-generated arguments and finally analyze the eight students' validations of them. (shrink)

Resumo (200 palavras) Podem-se encontrar diferentes conceitos na história da Ética. Esse artigo lida com a ideia que se deve identificar um conceito de Ética para se discutir sobre sua relação com Educação. Moral é um conceito que aparece quando se pensa sobre Ética. Por isso uma discussão sobre o conceito de Moral e sua relação com Ética é apresentado. Discutir Ética significa entender o conceito na sociedade porque Ética não pode acontecer a uma pessoa sozinha. Pessoas se relacionam na (...) sociedade e Ética é o fundamento básico da vida social. Antes que se possa observar Ética na sociedade como um conjunto, é possível descobrir que Ética começa na vida da família. A escola é o lugar específico na sociedade que ajuda a família a construir a relação entre Ética e Educação. Filósofos e educadores concordam sobre a importância de educar crianças para serem cidadãos éticos, mas os conceitos de Ética que eles possam usar são de algum modo diferente. Ética Relativa e Ética Universal são os principais grupos de conceitos encontrados na literatura. Concluímos que para se tornar inteiramente um ser humano, cada pessoa precisa se sentir integrada à humanidade e isto somente é possível por meio de conceitos universais de ética. Palavras chaves – ética – educação – moral – família - escola - sociedade (200 words) We can find different concepts in history of Ethics. This article deals with the idea that it is necessary to identify a concept of Ethics in order to discuss about its relation to Education. Moral is a concept that comes to mind when we think about Ethics. Because of this a discussion about this concept and its relation to Ethics is presented. To discuss Ethics means to understand it in society because it can’t happen to a person alone. People relate themselves in society and Ethics is the basic foundation to social life. Before we can observe Ethics in society as a whole it is possible to discover that Ethics begins in family life. School is the specific place in society that helps family to build the relation between Ethics and Education. Philosophers and educators agree about the importance of educating children to be ethical citizens but concepts of Ethics they may use are somehow different. Relative Ethics and Universal Ethics are the major groups of concepts that we can find in literature. We conclude that to become a whole human being each person needs to feel integrated to humankind and this is only possible through universal concepts of Ethics.

Since Toulmin’s discovery of the field-dependency of arguments, and Perelman’s emphasis on audiences, argumentation theorists have developed the notion of “spheres of arguments” or “argument communities”. Since argument communities are communities of discourse guided by the participants’ cog-nitive experiences, they are also cognitive communities. “Cognitive breaks” between different argument communities will produce misunderstanding and futile argument. The paper will investigate “cognitive breaks” and describe in which ways they may obstruct reasonable argumentation between communities.

Douglas Walton’s multitudinous contributions to the study of argumentation seldom, if ever, directly engage with argumentation in mathematics. Nonetheless, several of the innovations with which he is most closely associated lend themselves to improving our understanding of mathematical arguments. I concentrate on two such innovations: dialogue types (§1) and argumentation schemes (§2). I argue that both devices are much more applicable to mathematical reasoning than may be commonly supposed.

Bullshit is not the only sort of deceptive talk. Spurious definitions are another important variety of bad reasoning. This paper will describe some of these problematic tactics, and show how Harry Frankfurt’s treatment of bullshit may be extended to analyze their underlying causes. Finally, I will deploy this new account of definition to assess whether Frankfurt’s definition of bullshit is itself legitimate.

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 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.

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)

The concept of warrant reflects Toulmin's general insights that validity in reasoning comes in many forms, and that reasoning in most fields cannot possess the necessity and certainty characteristic of the 'Rationalist' paradigm. However, there is a scarcity of concepts in one part of Toulmin's theory of argument. While the pedagogical applications of Toulmin's model offer a fine-grained system of warrant types for propositions, they have only one category of warrant for practical claims – the 'motivational' warrant. Fortunately, ancient rhetorical (...) thinking can help us correct this insufficiency. For example, the author of the rhetorical textbook used by Alexander the Great proposed a typology of practical warrants. His approach highlights what I propose to call the 'multidimensionality', and hence what modern moral philosophers call the 'incommensurability' of warrants – the absence of a common measure allowing for a 'rational' balancing of conflicting warrants. The widespread occurrence of multidimensionality in practical argument lends support to Toulmin's general anti-rationalist view of reasoning. Moreover, while multidimensionality prevents 'rational' balancing, it legitimizes and even necessitates the use of rhetoric in practical reasoning. (shrink)

In this paper, I investígate a question in the Rhetoric surrounding the metaphorical sense of Aristotle’s topos: one can look to a location for “available means of persuasion,” evoking an image of seeing ; or topoi are viewed as “general lines of argument.” Are they places we go for arguments, or actual lines of arguments? The difference matters, given a propensity to view topoi as forerunners of argument schemes.

This paper is concerned with the deconstruction of defeasible argument schemes. It will be claimed that one of the central elements of all defeasible argument schemes is the rule of similarity which demands that one must ascribe similar propositions to essentially similar entities in order to be treated as reasonable. This rule is presented as interculturally valid and of such central importance that it could even been used as a defining quality of defeasible argumentation.

This paper provides an analysis of the argument from cause and effect and a comparison of its various types with the argument from correlation. It will be claimed that arguments from causality and from correlation should be treated as equivalent for argumentative purposes. The main advantages of this approach as well as possible theo-retical objections will be discussed.

This study builds upon the ideas of Classical Pragmatists and Neo-pragmatists to suggest that metaphors can best be understood in terms of what they are used to do. What metaphors do, according to Davidson, is redirect our notice so as to effect new understandings. Davidson’s account, thus understood, appears to contradict the conclusions of structuralist accounts in which metaphorical meanings are derived from the supposed cognitive contents of utterances.

In this paper the authors give a brief overview of the theoretical background of their research project “Linguistic indicators of argumentative moves.” Starting from the pragma-dialectical ideal model of a critical discussion, they design dialectical profiles for capturing the moves that may or must be made at a particular stage or sub-stage of such a discussion. They explain how these dialectical profiles can be methodically exploited for systematically identifying the verbal expressions that can be indicative of any of these moves (...) in argumentative practice.

Perelman’s discussion about the distinction and relation between the rational and the reason-able could be seen as an attempt to bring forward a new understanding of rationality. In light of the concep-tion of situated reason, this paper argues that Perelman’s explication of the dialectic of the rational and the reasonable highlights the balance of universality and contexuality, and could contribute a fuller conception of rationality to establishing a solid philosophical foundation for Johnson’s informal logic.

The simplest statement of the relationship between consensus and dissensus is that arguments are supposed to begin in dissensus and end in consensus. This essay introduces a third state for argumentation, learned ignorance. Nicolas of Cusa’s De Docta Ignorantia lays out both a case and a logic for argumentation that is not designed to end in a clear conclusion. Instead, the arguer pursues a matter up to an inconclusive point, and ends there, satisfied with the results. The underlying logic of (...) this view is centered on the “coincidence of opposites,” which requires rejection of the usual logical principle that A and not-A cannot both be true. (shrink)

Using tools like argument diagrams and profiles of dialogue, this paper studies a number of examples of everyday conversational argumentation where determination of relevance and irrelevance can be assisted by means of adopting a new dialectical approach. According to the new dialectical theory, dialogue types are normative frameworks with specific goals and rules that can be applied to conversational argumentation. In this paper is shown how such dialectical models of reasonable argumentation can be applied to a determination of whether an (...) argument in a specific case is relevant are not in these examples. The approach is based on a linguistic account of dialogue and text from congruity theory, and on the notion of a dialectical shift. Such a shift occurs where an argument starts out as fitting into one type of dialogue, but then it only continues to makes sense as a coherent argument if it is taken to be a part of a different type of dialogue.

Borrowing from Plato, argumentation tends to imagine that invention is at home in the khôra—the space of the ideas—because it is the space for discovering and sorting argument options. In contrast, this paper suggests we re-conceive the idea of inventio as emerging possibility. Inventio is not only the process of sorting the set of possible arguments but is the possibility of the new idea itself; the idiomatic, the absolute surprise.

Humanist concerns to empower human beings and to promote justice inspired the modern argumentation movement. Turning to audience adherence and acceptability of inferential links raised a spectre of pernicious relativism that undermines concerns for justice. Invoking Perelman’s universal audi-ence as a remedy only begs the question with ‘whose universal audience?’ and frustrates fulfilling the jus-tice commitment. Turning discourse toward the common good better addresses concerns of justice and social justice.

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)
