Argumentation schemes are forms of reasoning that are fallible but correctable within a self-correcting framework. Their use provides a basis for taking rational action or for reasonably accepting a conclusion as a tentative hypothesis, but they are not deductively valid. We argue that teleological reasoning can provide the basis for justifying the use of argument schemes both in monological and dialogical reasoning. We consider how such a teleological justification, besides being inspired by the aim of directing a bounded cognizer to (...) true belief and correct choices, needs to take into account the attitudes of dialogue partners as well as normative models of dialogue and communicative activity types, in particular social and cultural settings.

Manipulation of quotation, shown to be a common tactic of argumentation in this paper, is associated with fallacies like wrenching from context, hasty generalization, equivocation, accent, the straw man fallacy, and ad hominem arguments. Several examples are presented from everyday speech, legislative debates and trials. Analysis using dialog models explains the critical defects of argumentation illustrated in each of the examples. In the formal dialog system CB, a proponent and respondent take turns in making moves in an orderly goal-directed sequence (...) of argumentation in which the proponent tries to persuade the respondent to become committed to a conclusion by asking questions and offering arguments. Analyzing quotation by using the notion of commitment in dialog, it is shown (a) how an arguer’s previous assertions can be brought to light in the course of a dialog to deal with problems arising from misquotation, (b) how the profile of dialog model allows a critic to analyse the fundamental effects misquotation brings about in a dialog, and (c) how the critic can use such an analysis to correct the problem.

The article focuses on the new rhetoric category of quasi-logical arguments, defined as arguments similar to logical or mathematical demonstrations, and therefore having an effect on the audience. Connecting the similarity of arguments to formal demonstrations with the claim of effect on audience is conceived in this article as the thesis of effectiveness of quasi-logical arguments. The components of the thesis are reconstructed and analyzed, and their precise definitions are proposed. The analysis shows that the category of quasi-logical arguments is (...) ambiguously defined and currently includes three different concepts based on a different understanding of similarity. Subsequently, it is showed that based on Perelman and Olbrechts-Tyteca’s works, the explanation of quasi-logical arguments’ effect on an audience can be offered in terms of socially shared standards of community or in terms of individual processing of arguments. It is shown that these explanations can be in conflict each other regarding the assumption of the addressee’s acquaintance with formal principles. (shrink)

The implicit dimension of enthymemes is investigated from a pragmatic perspective to show why a premise can be left unexpressed, and how it can be used strategically. The relationship between the implicit act of taking for granted and the pattern of presumptive reasoning is shown to be the cornerstone of kairos and the fallacy of straw man. By taking a proposition for granted, the speaker shifts the burden of proving its un-acceptability onto the hearer. The resemblance of the tacit premise (...) with what is commonly acceptable or has been actually stated can be used as a rhetorical strategy. (shrink)

Why are personal attacks so powerful? In political debates, speeches, discussions and campaigns, negative character judgments, aggressive charges and charged epithets are used for different purposes. They can block the dialogue, trigger value judgments and influence decisions; they can force the interlocutor to withdraw a viewpoint or undermine his arguments. Personal attacks are not only multifaceted dialogical moves, but also complex argumentative strategies. They can be considered as premises for further arguments based on signs, generalizations or consequences. They involve tactics (...) for arousing emotions such as fear, hate or contempt, or for ridiculing the interlocutor. The twofold level of investigation presented in this paper is aimed at distinguishing the different roles that ad hominem have in a dialogue and bringing to light their hidden dimensions. The reasoning structure of each type of attack will be distinguished from the tactics used to increase its effectiveness and conceal its weaknesses. (shrink)

This paper compares current ways of modeling the inferential structure of practical reasoning arguments, and proposes a new approach in which it is regarded in a modular way. Practical reasoning is not simply seen as reasoning from a goal and a means to an action using the basic argumentation scheme. Instead, it is conceived as a complex structure of classificatory, evaluative, and practical inferences, which is formalized as a cluster of three types of distinct and interlocked argumentation schemes. Using two (...) real examples, we show how applying the three types of schemes to a cluster of practical argumentation allows an argument analyst to reconstruct the tacit premises presupposed and evaluate the argumentative reasoning steps involved. This approach will be shown to overcome the limitations of the existing models of practical reasoning arguments within the BDI and commitment theoretical frameworks, providing a useful tool for discourse analysis and other disciplines. In particular, applying this method brings to light the crucial role of classification in practical argumentation, showing how the ordering of values and preferences is only one of the possible areas of deep disagreement.

This paper shows how reasoning from best explanation combines with linguistic and factual presumptions during the process of retrieving a speaker’s intention. It is shown how differences between presumptions need to be used to pick the best explanation of a pragmatic manifestation of a dialogical intention. It is shown why we cannot simply jump to an interpretative conclusion based on what we presume to be the most common purpose of a speech act, and why, in cases of indirect speech acts, (...) we need to depend on an abductive process of interpretation.

In lieu of an abstract, here is a brief excerpt of the content:A Bibliography of the New Rhetoric ProjectDavid A. Frank and William DriscollScholars do not have access to a complete bibliography of the new rhetoric project. We have redressed this problem by compiling what we believe is the most comprehensive bibliography to date of the works of Chaïm Perelman and of those he coauthored with Lucie Olbrechts-Tyteca. The bibliography includes all the English and French titles, as well as titles (...) that saw first publication in other languages. Translations we believe Perelman may have authorized or endorsed are included.With this bibliography, scholars can now better understand how the new rhetoric project was conceived and how it unfolded. Within the larger constellation of the project, Perelman's bibliography is the most extensive, numbering almost three hundred entries. The trajectory of Perelman's scholarship reveals the origins of the new rhetoric project and how it evolved between the time of his announcement in 1949 that he and Olbrechts-Tyteca had embarked on a program designed to rehabilitate reason and the period of his final articles in the 1980s. A review of the articles and books that came out of the Perelman and Olbrechts-Tyteca collaboration reveals both a phase of conceptualization and development of the project and a phase of culmination. In the first phase, commencing with Rhétorique et philosophie, the authors established the need for a rhetorically grounded philosophy. As they built toward the publication of the Traité, [End Page 449] the culmination of their ten-year effort, they wrote articles elaborating on "notions" in argumentation (1955) and on the tenets of the "new rhetoric" (1956). In 1958, the year the Traité appeared, they published articles on classical and romantic loci in argumentation and on time in argumentation. With the exception of a 1983 tribute to the theorist Pareto, they did not write together after 1958 but instead pursued separate lines of research out of their collaboration. A significant number of theses entries rehearse and embellish notions introduced between 1947 and 1958, the years of the genesis, development, and culmination of Chaïm Perelman and Lucie Olbrechts-Tyteca's new rhetoric project.AbbreviationsChALe champ de l'argumentationDMPDroit, morale, et philosophieEDEthique et droitIJPAThe Idea of Justice and the Problem of ArgumentJLAJustice, Law, and Argument: Essays on Moral and Legal ReasoningNRHThe New Rhetoric and the Humanities: Essays on Rhetoric and Its ApplicationsJJusticeJRJustice et raisonRPRhétorique et philosophie pour une théorie de l'argumentation en philosophieBibliography1931 "Esquisse d'une logistique des valeurs."

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.

The author compares two theoretical models which develop constructs of an ideal audience. Chaim Perelman's universal audience serves a methodological function within the New Rhetoric which provides for the examination of philosophical arguments on values. Implicit within the work of Isocrates is a competing image which asserts that the ideal audience is empowered by the conditions of argument to engage the advocate in discursive praxis to construct and embody a consensus on contingency-driven value debates. The author concludes that the concept (...) of an ideal audience will be most valuable where interest in adherence to theses is less central than attendance to relationships born in and borne by discourse. Such a view has purchase within a constitutive view of rhetorical relations which asserts that the most useful role for argument is as an invitation to engagement. The situation of argumentation within a deontological ethics requires the partnership and participation of individuals in a mutually constructed discursive praxis. (shrink)

In this paper, we use concepts, structure and tools from argumentation theory to show how conversational implicatures are triggered by conflicts of presumptions. Presumptive implicatures are shown to be based on defeasible forms of inference used in conditions of lack of knowledge, including analogical reasoning, inference to the best explanation, practical reasoning, appeal to pity, and argument from cause. Such inferences are modelled as communicative strategies to knowledge gaps that shift the burden of providing the missing contrary evidence to the (...) other party in a dialogue. Through a series of illustrative examples, we show how such principles of inference are based on common knowledge about the ordinary course of events shared by participants in a structured dialogue setting in which they take turns putting forward and responding to speech acts.

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.
