In this paper we consider persuasion in the context of practical reasoning, and discuss the problems associated with construing reasoning about actions in a manner similar to reasoning about beliefs. We propose a perspective on practical reasoning as presumptive justification of a course of action, along with critical questions of this justification, building on the account of Walton. From this perspective, we articulate an interaction protocol, which we call PARMA, for dialogues over proposed actions based on this theory. We outline (...) an axiomatic semantics for the PARMA Protocol, and discuss two implementations which use this protocol to mediate a discussion between humans. We then show how our proposal can be made computational within the framework of agents based on the Belief-Desire-Intention model, and illustrate this proposal with an example debate within a multi agent system.

Rather than the art of putting forward logically valid arguments leading to Truth, argumentation is here viewed as the use of verbal means ensuring an agreement on what can be considered reasonable by a given group, on a more or less controversial matter. What is acceptable and plausible is always coconstructed by subjects engaging in verbal interaction. It is the dynamism of this exchange, realized not only in natural language, but also in a specific cultural framework, that has to be (...) accounted for. From this perspective, it is not enough to reconstruct patterns of reasoning. As logos is by definition both Reason and Language, abstract schemata have to be examined in their verbal realization in a given situation of discourse. Such an approach to arguments allows for a “thick” description taking into account their discursive and communicational aspects, as well as argumentation’s constitutive dialogism and its inscription in a set of common representations, opinions and beliefs (a doxa). This approach, exemplified by the analysis of a short text on stock options borrowed from the French newspaper Libération, is an attempt at establishing a dialogue between disciplines like argumentation theories, rhetorical criticism and discourse analysis.

We provide for the first time an exact translation into English of the Polish version of Alfred Tarski's classic 1936 paper, whose title we translate as ?On the Concept of Following Logically?. We also provide in footnotes an exact translation of all respects in which the German version, used as the basis of the previously published and rather inexact English translation, differs from the Polish. Although the two versions are basically identical, to an extent that is even uncanny, we note (...) more than 400 differences. Several dozen of these are substantive differences due to revisions by Tarski to the Polish version which he did not incorporate in the German version. With respect to these revisions the Polish version should be regarded as more authoritative than the German. Hence scholars limited to an English translation should use ours. (shrink)

Our aim is to point out some differences between verbal and visual arguments, promoting the rhetorical perspective of argumentation beyond the relevance of logic and pragmatics. In our view, if it is to be rational and successful, film as (visual) argumentation must be addressed to spectators who hold informed beliefs about the theme watched on the screen and the medium’s constraints and conventions. In our reflections to follow, we apply rhetorical analysis to film as a symbolic, human, and communicative act (...) that may sometimes be understood as a visually laid out argument. As a mixture of visual, auditory, and verbal stimuli, film demands active and complex interpretation and (re)construction. Our suggestion is to focus on five different but interrelated elements. The reconstruction and evaluation of the visual argument will be based on those elements, and the whole process will be one of visual argumentation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Perelmanian Universal Audience and the Epistemic Aspirations of ArgumentScott F. AikinIThe notion of universality in argumentation is as fecund as is it is controversial. Chaïm Perelman and Lucie Olbrechts-Tyteca’s notion of universal audience (UA), given their requirement that all arguments be evaluated in terms of their audiences, clearly promises a rich account of argumentative norms. It equally yields a variety of questions. For the most part, the questions come (...) in three forms: what, precisely, is the universal audience; whether it is, in the end, a coherent notion; and how its norms actually constrain argument. Many objections to the notion claim that it is either incoherent or too empty to constrain. My objective here is to provide an account of Perelman’s notion of UA that avoids these objections. I will argue that the UA can be clarified with a distinction between two functions it plays in argumentation— one pragmatic and another epistemic. Perelman and Olbrechts-Tyteca do not explicitly disambiguate these roles themselves, though they do use the notion in two distinct ways in The New Rhetoric (TNR [1969]), and so it seems clear that although the view in the end may be Perelmanian, it is arguably not Perelman’s. No matter. The purpose of this essay is not to exhume Perelman but to resurrect and exercise his views. That is, historical work in philosophy must straddle the demands of two distinct goals— fidelity to the author in question and defensibility of the views developed. My case [End Page 238] will jointly depend on the comparative plausibility of my account as an interpretation of Perelman’s universal audience and of the view as correct regarding argumentative norms in relation to the other competing interpretations of Perelman’s UA. So if my argument for a divided universal audience is at least Perelmanian in spirit, and if it survives the objections to UA that other interpretations do not survive, it should be the philosophically preferable interpretation.IIThe first principle of Perelmanian rhetoric is that arguments are addressed to audiences for the purpose of inducing or increasing adherence to a view (TNR, 14). Consequently, the less reliant arguments are on a specific audience’s idiosyncratic commitments, the more effective the arguments will be in generating assent and resolving disagreements in wider and wider groups of people. Perelman describes the universal audience in The Realm of Rhetoric (RR [1982]) as “itself... made up of an infinite variety of particular audiences” (14). The UA is the regulative ideal of maximal intersubjective agreement. That is, we see both the relative weakness of arguments that depend on the commitments of particular audiences and “the value attached to opinions that enjoy unanimous approval” (TNR, 31). This unanimity is reached at its highest point in the universal audience. As such, UA is an agglomerative notion that functions as a criterion for how widely an argument may be given credence. Call this trajectory toward unanimity the pragmatic element of UA.However, the universal audience’s assent is used to define facts for arguments, and as such, it is a marker of the objectivity of a conclusion, not just the breadth of the effectiveness of an argument. Perelman and Olbrechts-Tyteca stipulate that “from the standpoint of argumentation, we are confronted with a fact only if we can postulate uncontroverted, universal agreement with respect to it” (TNR, 67). Facts and truths are defined in terms of the “agreement of the universal audience” (TNR, 67). This, of course, is not to say that arguments make facts but, instead, that their universal acceptability is a criterion for whether some purported fact is or is not the case. Agreement on this level does not play a metaphysical role of explanation but, rather, a cognitive role of justification for taking a commitment as a premise for further argument. The agreement in a universal audience, further, must be uncontroverted, which means that this UA must have some shared commitment that survives scrutiny (or at least is [End Page 239] not defeated): “The agreement of a universal audience is... a matter, not of fact, but of right” (TNR, 31). And further, this right has a very powerful normative element: “Argumentation... (shrink)

Conductive Arguments are held to be defeasible, non-conclusive, and neither inductive nor deductive (Blair and Johnson in Conductive argument: An overlooked type of defeasible reasoning. College, London, 2011). Of the different kinds of Conductive Arguments, I am concerned only with those for which it is claimed that countervailing considerations detract from the support for the conclusion, complimentary to the positive reasons increasing that support. Here’s an example from Wellman (Challenge and response: justification in ethics. Southern Illinois University Press, Chicago, 1971): (...) Although your lawn needs cutting, you ought to take your son to the movies because the picture is ideal for children and will be gone by tomorrow. (1971: 57) I argue that Conductive Arguments are not possible—the “ought” conclusion only holds if countervailing considerations are nullified. (shrink)

Stephen Toulmin once observed that ”it has never been customary for philosophers to pay much attention to the rhetoric of mathematical debate’ [Toulmin et al., 1979, An Introduction to Reasoning, Macmillan, London, p. 89]. Might the application of Toulmin’s layout of arguments to mathematics remedy this oversight? Toulmin’s critics fault the layout as requiring so much abstraction as to permit incompatible reconstructions. Mathematical proofs may indeed be represented by fundamentally distinct layouts. However, cases of genuine conflict characteristically reflect an underlying (...) disagreement about the nature of the proof in question. (shrink)

This study investigates how dispute-mediators handle impasse in the re-negotiation of divorce decrees by divorced couples. Three sources of impasse and three strategies for handling impasse are identified based on analysis of mediation transcripts. The concern here lies not so much in the disputant's arguments but in the discussion procedures dispute-mediators use to craft the disputant's argumentation into a tool to solve conflict. Their moves are understood here as a practice of reconstructing argumentative discourse that is neither naïve nor critical (...) but reconstruction as design. Mediator's reconstruction reveals a type of communication work in contemporary societies involved in the crafting of forums and formats that mediate argumentative communication. This work is often invisible and strategic which makes its interpretation, judgment, and development a challenge for pragma-dialectical theory. How reconstruction as design can be understood is discussed by building on prior pragma-dialectical theory and research. (shrink)

In The Uses of Argument, Toulmin proposed a distinction between fielddependent and field-invariant standards for argument appraisal that gave rise to a relativistic understanding of his theory. The main goal of this paper is to show that epistemological relativism is not a necessary consequence ofToulmin's model of argument. To this end, I will analyze the role that fields are to play within this model, given a certain conception of one of its key elements: the warrant of an argument.

Offering an innovative approach to critical thinking, Good Reasoning Matters! identifies the essential structure of good arguments in a variety of contexts and also provides guidelines to help students construct their own effective arguments. In addition to examining the most common features of faulty reasoning--slanting, bias, propaganda, vagueness, ambiguity, and a common failure to consider opposing points of view--the book introduces a variety of argument schemes and rhetorical techniques. This edition adds material on visual arguments and more exercises.

In this companion volume to Warrant: The Current Debate, Plantinga develops an original approach to the question of epistemic warrant; that is what turns true belief into knowledge. He argues that what is crucial to warrant is the proper functioning of one's cognitive faculties in the right kind of cognitive environment.

This two-volume work, first published in 1843, was John Stuart Mill's first major book. It reinvented the modern study of logic and laid the foundations for his later work in the areas of political economy, women's rights and representative government. In clear, systematic prose, Mill disentangles syllogistic logic from its origins in Aristotle and scholasticism and grounds it instead in processes of inductive reasoning. An important attempt at integrating empiricism within a more general theory of human knowledge, the work constitutes (...) essential reading for anyone seeking a full understanding of Mill's thought. Continuing the discussion of induction, Volume 2 concludes with Book VI, 'On the Logic of the Moral Sciences', in which Mill applies empirical reasoning to human behaviour. A crucial early formulation of his thinking regarding free will and necessity, this book establishes the centrality of 'the social science' to Mill's philosophy. (shrink)

Francis Bacon, lawyer, statesman, and philosopher, remains one of the most effectual thinkers in European intellectual history. We can trace his influence from Kant in the 1700s to Darwin a century later. The Advancement of Learning , first published in 1605, contains an unprecedented and thorough systematization of the whole range of human knowledge. Bacon’s argument that the sciences should move away from divine philosophy and embrace empirical observation would forever change the way philosophers and natural scientists interpret their world.

Knowledge in a Social World offers a philosophy for the information age. Alvin Goldman explores new frontiers by creating a thoroughgoing social epistemology, moving beyond the traditional focus on solitary knowers. Against the tides of postmodernism and social constructionism Goldman defends the integrity of truth and shows how to promote it by well-designed forms of social interaction. From science to education, from law to democracy, he shows why and how public institutions should seek knowledge-enhancing practices. The result is a bold, (...) timely, and systematic treatment of the philosophical foundations of an information society. (shrink)

A foundational text in modern empiricist method, published in 1843 by Victorian England's foremost philosopher of political and social life.

This collection of essays examines the ways in which disputes and controversies about the application of scientific knowledge are resolved. Four concrete examples of public controversy are considered in detail: the efficacy of Laetrile, the classification of homosexuality as a disease, the setting of safety standards in the workplace, and the utility of nuclear energy as a source of power. The essays in this volume show that debates about these cases are not confined to matters of empirical fact. Rather, as (...) is seen with most scientific and technical controversies, they focus on and are structured by complex ethical, economic, and political interests. Drs. Engelhardt and Caplan have brought together a distinguished group of scholars from the sciences and humanities, who sketch a theory of scientific controversy and attempt to provide recommendations about the ways in which both scientists and the public ought to seek more informed resolutions of highly contentious issues in science and technology. Scientific Controversies is offered as a contribution to the better understanding of the roles of both science and nonscientific interests in disputes and controversies pertaining to science and technology.

In Ciceronis Topica and De topicis differentiis are Boethius's two treatises on Topics. Together these two works present Boethius's theory of the art of discovering arguments, a theory that was highly influential in the history of medieval logic.

A theory of analogy must describe how the meaning of an analogy is derived from the meanings of its parts. In the structure‐mapping theory, the interpretation rules are characterized as implicit rules for mapping knowledge about a base domain into a target domain. Two important features of the theory are (a) the rules depend only on syntactic properties of the knowledge representation, and not on the specific content of the domains; and (b) the theoretical framework allows analogies to be distinguished (...) cleanly from literal similarity statements, applications of abstractions, and other kinds of comparisons.Two mapping principles are described: (a) Relations between objects, rather than attributes of objects, are mapped from base to target; and (b) The particular relations mapped are determined by systematicity, as defined by the existence of higher‐order relations.
