Short abstract (98 words). Reasoning is generally seen as a means to improve knowledge and make better decisions. However, much evidence shows that reasoning often leads to epistemic distortions and poor decisions. This suggests that the function of reasoning should be rethought. Our hypothesis is that the function of reasoning is argumentative. It is to devise and evaluate arguments intended to persuade. Reasoning so conceived is adaptive given humans’ exceptional dependence on communication and vulnerability to misinformation. A wide range of (...) evidence in the psychology of reasoning and decision making can be reinterpreted and better explained in the light of this hypothesis. (shrink)

In this, the first of two ground-breaking volumes on the nature of language in the light of the way it evolved, James Hurford looks at how the world first came ...

Though textbook tu quoque arguments are fallacies of relevance, many versions of arguments from hypocrisy are indirectly relevant to the issue. Some arguments from hypocrisy are challenges to the authority of a speaker on the basis of either her sincerity or competency regarding the issue. Other arguments from hypocrisy purport to be evidence of the impracticability of the opponent’s proposals. Further, some versions of hypocrisy charges from impracticability are open to a counter that I will term tu quoque judo.

Humans are expert users of metarepresentations. How has this human metarepresentational capacity evolved? In order to contribute to the ongoing debate on this question, the chapter focuses on three more specific issues: i. How do humans metarepresent representations? ii. What came first: language, or metarepresentations? iii. Do humans have more than one metarepresentational ability?

Language is both a biological and a cultural phenomenon. Our aim here is to discuss, in an evolutionary perspective, the articulation of these two aspects of language. For this, we draw on the general conceptual framework developed by Ruth Millikan (1984) while at the same time dissociating ourselves from her view of language.

This article addresses the relationship between understanding and believing from the cognitive perspective of information-processing. I promote, within the scope of the Critical Discourse Analysis agenda, the relevance of an account of belief-fixation sustained by a combination of argumentative and cognitive insights. To this end, I first argue that discursive strategies fulfilling legitimization purposes, such as evidentials, tap into the same cognitive mechanisms as arguments. I then proceed to examine the idea that the most effective arguments are the ones that (...) manage to obscure or make irrelevant counter-evidence and propose, from a cognitive pragmatic perspective, a formulation of rhetorical effectiveness as a constraint on information-selection taking place at the interpretation stage and decisively influencing the evaluation stage responsible for belief-fixation.

This article described three heuristics that are employed in making judgements under uncertainty: representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and adjustment from an anchor, which is usually employed in numerical prediction when a relevant value (...) is available. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgements and decisions in situations of uncertainty. (shrink)

Much evidence has accumulated in favor of such a dual view of reasoning. There is however some vagueness in the way the two systems are characterized. Instead of a principled distinction, we are presented with a bundle of contrasting features - slow/fast, automatic/controlled, explicit/implicit, associationist/rule based, modular/central - that, depending on the specific dual process theory, are attributed more or less exclusively to one of the two systems. As Evans states in a recent review, “it would then be helpful to (...) have some clear basis for this distinction”; he also suggests that “we might be better off talking about type 1 and type 2 processes” rather than systems. We share the intuitions that drove the development of dual system theories. Our goal here is to propose in the same spirit a principled distinction between two types of inferences: ‘intuitive inference’ and ‘reflective inference’. We ground this distinction in a massively modular view of the human mind where metarepresentational modules play an important role in explaining the peculiarities of human psychological evolution. We defend the hypothesis that the main function of reflective inference is to produce and evaluate arguments occurring in interpersonal communication. This function, we claim, helps explain important aspects of reasoning. We review some of the existing evidence and argue that it gives support to this approach. (shrink)

Fundamentals of Critical Argumentation presents the basic tools for the identification, analysis, and evaluation of common arguments for beginners. The book teaches by using examples of arguments in dialogues, both in the text itself and in the exercises. Examples of controversial legal, political, and ethical arguments are analyzed. Illustrating the most common kinds of arguments, the book also explains how to evaluate each kind by critical questioning. Douglas Walton shows how arguments can be reasonable under the right dialogue conditions by (...) using critical questions to evaluate them. The book teaches by example, both in the text itself and in exercises, but it is based on methods that have been developed through the author's thirty years of research in argumentation studies.

Critical Discourse Analysis has recently begun to consider the implications of research in Evolutionary Psychology for political communication. At least three positions have been taken: i) that this research requires Critical Discourse Analysis to re-examine and defend some of its foundational assumptions ; ii) that this research provides a useful explanatory framework for Critical Discourse Analysis in which questions can be addressed as to why speakers might pursue particular discursive strategies and why they might be so persuasive ; and iii) (...) that findings bare little or no relevance for Critical Discourse Analysis. In this article, I take up the first two of these positions and in doing so, of course, implicitly disagree with the third. I consider the positions in i) and ii), then, specifically in relation to Sperber’s notion of a ‘logico-rhetorical’ module. Taking the argument that Chilton makes concerning this module one stage further, I suggest that the logico-rhetorical module evolved as much for persuasion as it did for vigilance. I further suggest that the semantic category of evidentiality operationalized in media discourse serves to satisfy the conditions of acceptance laid down by the logico-rhetorical module. I show how this semantic category therefore performs a legitimizing function in media discourse on immigration. (shrink)
