ArgumentEvolutionary psychologists argue that because humans are biological creatures, cultural explanationsmustinclude biology. They thus offer to unify the natural and social sciences. Evolutionary psychologists rely on a specific history of cultural anthropology, particularly the work of Alfred Kroeber to make this point. A close examination of the history of cultural anthropology reveals that Kroeber acknowledged that humans were biological and culture had a biological foundation; however, he argued that we should treat culture as autonomous because that would bring benefits to (...) the biological sciences as well as the human sciences. Hence, the historical caricature of his work by evolutionary psychology fails. The paper concludes that cultural anthropologists were successful in creating their discipline, at least in part, because they argued by pragmatic definition. Evolutionary psychology, on the other hand, offers an essentialist definition of “culture” and thus offers a much less promising vision of interdisciplinary collaboration. (shrink)

In this paper we present an analysis of persuasive definition based on argumentation schemes. Using the medieval notion of differentia and the traditional approach to topics, we explain the persuasiveness of emotive terms in persuasive definitions by applying the argumentation schemes for argument from classification and argument from values. Persuasive definitions, we hold, are persuasive because their goal is to modify the emotive meaning denotation of a persuasive term in a way that contains an implicit argument from values. However, our (...) theory is different from Stevenson’s, a positivistic view that sees emotive meaning as subjective, and defines it as a behavioral effect. Our proposal is to treat the persuasiveness produced by the use of emotive words and persuasive definitions as due to implicit arguments that an interlocutor may not be aware of. We use congruence theory to provide the linguistic framework for connecting a term with the function it is supposed to play in a text. Our account allows us to distinguish between conflicts of values and conflicts of classifications. (shrink)

The recent redefinition of 'planet' that excludes Pluto as a planet led to controversy that provides a case study of how competing scientific definitions can be supported by characteristic types of evidence. An argumentation scheme from Hastings is used to analyze argument from verbal classification as a form of inference used in rational argumentation. The Toulmin-style format is compared to more recently developed ways of modeling such cases that stem from advances in argumentation technology in artificial intelligence. Using these tools, (...) it is shown how argumentation schemes, in particular argument from verbal classification and argument from definition to verbal classification, apply to cases of scientific argumentation.

In this paper we analyze the uses and misuses of argumentation schemes from verbal classification, and show how argument from definition supports argumentation based on argument from verbal classification. The inquiry has inevitably included the broader study of the concept of definition. The paper presents the schemes for argument from classification and for argument from definition, and shows how the latter type of argument so typically supports the former. The problem of analyzing arguments based on classification is framed in a (...) structure that reveals the crucial role it plays in the persuasion process. The survey of the literature includes the work of Hastings, Perelman, Kienpointner and Schiappa, but still finds much of value in Aristotle. Lessons drawn from Aristotle’s Topics are shown to be useful for developing new tools for assessing definitions and arguments from definition. (shrink)

In this paper, the political pamphlet “Der Hessische Landbote” by the eminent German author, Georg Büchner (1813–1837), will be positioned within the context of its political and historical background, analyzed as to its argumentative and stylistic structure, and critically evaluated. It will be argued that propaganda texts such as this should be evaluated by taking into account both rhetorical perspectives and standards of rational discussion. As far as argumentative structure is concerned, a modified version of the Toulmin scheme will be (...) used for the description of three passages of the “Landbote”. As far as stylistic techniques are concerned, Büchner’s strategic use of some figures of speech, especially parallelism, metaphor and metonymy will be examined. As to the critical evaluation, the recently developed concept of “strategic maneuvering” within Pragma-Dialectics, the typology of argumentative dialogues established by D. Walton, and sets of critical questions will be used to assess the status of the arguments within the “Landbote” as potentially fallacious ones. (shrink)

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.

Legal definitions will be examined from three perspectives: their pragmatic function, their propositional structure, and their argumentative role. In law, definitions can be used for different pragmatic purposes: they can be uttered to describe a concept, or to establish a new meaning for a term. The propositional content of definitional speech acts can be different. In law, like in ordinary conversation, there might be different types of definition: we can define by providing examples, or showing the fundamental characteristics of the (...) concept defined, or listing the constituent parts of the denotatum. All these definitions play different argumentative roles in legal discourse. At a third level, definitions can be thought of as premises in complex patterns of reasoning (for the subject of reasoning from definition in law, see Aarnio 1977; Moore 1980; Lindahl, 2004). They constitute the fundamental element of argument from classification, namely a pattern of inference in which a new property (or a name) is attributed to an entity on the basis of other properties.

The aim of the article is to defi ne a certain type of argumentation, which has been scarcely described so far in either Polish or foreign literature in the fi eld of argumentation theory, and thus to systematize the problems of research on semantic procedures in argumentation. The analysis of the ways in which a modifi cation of meaning can affect the power of arguments inclines to distinguish a new type of argumentation - semantic argumentation. The concepts of persuasive defi (...) nition and classifi cation as well as methods of their application in the formulation of an argument will also be analyzed. The defi nition of semantic argumentation proposed here may give rise to some problems, typical when introducing a new concept, which is why the second part of the article is devoted to the issues related to the proposed shape of the defi nition. The defi nition is necessary for further research on semantic argumentation, its typology and for the assessment of its correctness. (shrink)

What distinguishes the philosophies of education advanced by pragmatists? Does pragmatism have something distinctive to offer contemporary philosophy of education? This paper applies these questions, which Randall Curren asks in “Pragmatist Philosophy of Education” (2009), to a more specific current debate in philosophy of education: the debate over educating for critical thinking, and/or for intellectual virtues. Which, if either, should be given priority in higher education, and why? This paper develops a Deweyan approach to these questions, inviting character content but (...) also offering specific ways for educators and institutions to stay alert to the pedagogical and indoctrination concerns with character education initiatives, including those for intellectual virtues specifically.

At a recent rally, Donald Trump resumed a habit he had developed during his election-rallies and read out the lyrics to a song. It tells the Aesopian fable of The Farmer and the Snake: A half frozen snake is taken in by a kind-hearted person but bites them the moment it is revived. Trump tells the fable to make a point about Islamic immigrants and undocumented immigrants from Southern and Central America: He claims the immigrants will cause problems and much (...) stricter immigration-policies are needed. I assume that Trump treats the fable as an argumentative device for supporting his stance on immigration. He uses it as a source-analogue both for the conclusion that immigrants will cause problems and for changing the frame in which immigrants and those willing to let them enter are seen. This gives me opportunity to examine the effect fables have as argumentative devices. Fables are a popular and effective choice for political argumentation. They are slimmed down, semi-abstract narratives, well suited for directing the audience's attention to a few properties of an otherwise complex situation. However, this also makes it easy to use them for manipulating an audience into oversimplifying complex contexts and stereotyping human beings. (shrink)
