The focus of this paper are Dummett's meaning-theoretical arguments against classical logic based on consideration about the meaning of negation. Using Dummettian principles, I shall outline three such arguments, of increasing strength, and show that they are unsuccessful by giving responses to each argument on behalf of the classical logician. What is crucial is that in responding to these arguments a classicist need not challenge any of the basic assumptions of Dummett's outlook on the theory of meaning. In particular, I (...) shall grant Dummett his general bias towards verificationism, encapsulated in the slogan 'meaning is use'. The second general assumption I see no need to question is Dummett's particular breed of molecularism. Some of Dummett's assumptions will have to be given up, if classical logic is to be vindicated in his meaning-theoretical framework. A major result of this paper will be that the meaning of negation cannot be defined by rules of inference in the Dummettian framework. (shrink)

In this paper, we closely examine the various ways in which a multi-party argumentative discussion—argumentative polylogue—can be analyzed in a dialectical framework. Our chief concern is that while multi-party and multi-position discussions are characteristic of a large class of argumentative activities, dialectical approaches would analyze and evaluate them in terms of dyadic exchanges between two parties: pro and con. Using as an example an academic committee arguing about the researcher of the year as well as other cases from argumentation literature, (...) we scrutinize the advantages and pitfalls of applying a dialectical framework to polylogue analysis and evaluation. We recognize two basic dialectical methods: interpreting polylogues as exchanges between two main camps and splitting polylogues into a multitude of dual encounters. On the basis of this critical inquiry, we lay out an argument expressing the need for an improved polylogical model and propose its basic elements. (shrink)

Digressions in argumentative discussion are a kind of failure of relevance. Examination of what actual cases look like reveals several properties of argumentative relevance: (1) The informational relevance of propositions to the truth value of a conclusion should be distinguished from the pragmatic relevance of argumentative acts to the task of resolving a disagreement. (2) Pragmatic irrelevance is a collaborative phenomenon. It does not just short-circuit reasoning; it encourages a failure to take up the demands of an argumentative task. (3) (...) Pragmatic irrelevance can occur not simply by the absence of a connection between what is said and some standpoint in dispute, but also by the presence of a connection between what is said and a competing use of the information. (4) Pragmatic relevance must be accomplished through communicative action. (shrink)

The common view is that no novel IS an argument, though it might be reconstructed as one. This is curious, for we almost always feel the need to reconstruct arguments even when they are uncontroversially given as arguments, as in a philosophical text. We make the points as explicit, orderly, and (often) brief as possible, which is what we do in reconstructing a novel’s argument. The reverse is also true. Given a text that is uncontroversially an explicit, orderly, and brief (...) argument, in order to enhance plausibility, our first instinct is to flesh it out with illustrations and relationships to everyday life. If this process is fictive (e.g., with “thought experiments”) and orderly, it is story-telling. This paper investigates whether there is a principled way of determining a novel’s argument, which should contribute as much to understanding arguments as to understanding novels. (shrink)

Modern empiricism has been conditioned in large part by two dogmas. One is a belief in some fundamental cleavage between truths which are analytic, or grounded in meanings independently of matters of fact, and truth which are synthetic, or grounded in fact. The other dogma is reductionism: the belief that each meaningful statement is equivalent to some logical construct upon terms which refer to immediate experience. Both dogmas, I shall argue, are ill founded. One effect of abandoning them is, as (...) we shall see, a blurring of the supposed boundary between speculative metaphysics and natural science. Another effect is a shift toward pragmatism. (shrink)

A compact, coherent introduction to the study of rational belief, this text provides points of entry to such areas of philosophy as theory of knowledge, methodology of science, and philosophy of language. The book is accessible to all undergraduates and presupposes no philosophical training.

In what does the sense of a sentential connective consist? Like many others, I hold that its sense lies in rules that govern deductions. In the present paper, however, I argue that a classical logician should take the relevant deductions to be arguments involving affirmative or negative answers to yes-or-no questions that contain the connective. An intuitionistic logician will differ in concentrating exclusively upon affirmative answers. I conclude by arguing that a well known intuitionistic criticism of classical logic fails if (...) the answer "No" is accorded parity with the answer "Yes". (shrink)

The “ultimate objective” of this book, says David Schmidtz, “is to examine the degree to which being moral is co-extensive with being rational”. For Schmidtz, an “end” gives us a reason for action provided that its pursuit is not undercut by some other end. Morality has a two-part structure. A person’s goal is “moral” if “pursuing it helps [her] to develop in a reflectively rational way,” provided its pursuit does not violate “interpersonal moral constraints”. Interpersonal constraints are imposed by “collectively (...) rational” social institutions, institutions that “make people in general better off by nonexploitative means”. Schmidtz’s view is a form of “actualism.” Our reasons are given by our actual goals, subject to the qualification mentioned above, and moral constraints are given by actually existing collectively rational institutions. Schmidtz concedes that this framework cannot guarantee that it is rational for every agent to be moral, and he concedes that his moral theory might be incomplete. Nevertheless, he argues, “morality and rationality make room for each other in a variety of ways”. (shrink)

He further argues that it is necessary to rethink traditional conceptions of argument, and to find a position that avoids the limitations of both the highly abstract approach of formal logic and the highly contextualized approaches of rhetoric and communication theory.".

A critical examination of the dialectical approach, focusing on a comparison ofthe illative and the dialectical definitions of argument. I distinguish a moderate, a strong and a hyper dialectical conception of argument. I critique Goldman's argument for the moderate conception and Johnson's argument for the strong conception, and argue that the moderate conception is correct.

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)

This paper gives an account of the differences between polar and alternative questions, as well as an account of the division of labor between compositional semantics and pragmatics in interpreting these types of questions. Alternative questions involve a strong exhaustivity presupposition for the mentioned alternatives. We derive this compositionally from the meaning of the final falling tone and its interaction with the pragmatics of questioning in discourse. Alternative questions are exhaustive in two ways: they exhaust the space of epistemic possibilities, (...) as well as the space of discourse possibilities (the Question Under Discussion). In contrast, we propose that polar questions are the opposite: they present just one alternative that is necessarily non-exhaustive. The account explains a range of response patterns to alternative and polar questions, as well as differences and similarities between the two types of questions. (shrink)

The paper's thesis is that dialogue is not an adequate model for all types of argument. The position of Walton is taken as the contrary view. The paper provides a set of descriptions of dialogues in which arguments feature in the order of the increasing complexity of the argument presentation at each turn of the dialogue, and argues that when arguments of great complexity are traded, the exchanges between arguers are turns of a dialogue only in an extended or metaphorical (...) sense. It argues that many of the properties of engaged back-and-forth exchanges of paradigmatic argument dialogues are not found in ‘solo’ arguments, and that at least some of the norms appropriate to the former type of argument, such as some of the pragma-dialectical rules of van Eemeren and Grootendorst's model, do not apply to the latter.

In this paper it is shown how tools developed in argumentation theory and artificial intelligence can be applied to the development of a new dialectical analysis of the speech act of making a proposal in a deliberation dialogue. These tools are developed, modified and used to formulate dialogue pre-conditions, defining conditions and post-conditions for the speech act of making a proposal in a deliberation dialogue. The defining conditions set out what is required for a move in a dialogue to count (...) as the making of a proposal by one of the parties. What is required are the conditions that (1) the move fit the requirements of the argumentation scheme for practical reasoning, and (2) the premises are propositions describing common goals of both parties or propositions that they reasonably consider means to achieve these goals. The analysis goes beyond the standard speech act approach by specifying not only the normative requirements for making a well-formed proposal, but also the requirements for responding to it by questioning or criticizing it, and the requirements for defending it.

Starting from a concept of reasonableness as well-consideredness, it is discussed in what way science could serve as a model for reasonable argumentation. It turns out that in order to be reasonable two requirements have to be fulfilled. The argumentation should comply with rules which are both problem-valid and intersubjectively valid. Geometrical and anthropological perspectives don't meet these criteria, but a critical perspective does. It is explained that a pragma-dialectical approach to argumentation which agrees with this critical perspective is indeed (...) problem-valid and that strong pragmatic and utilitarian arguments can be given for its intersubjective validity. Thus, conventional validity is promoted for a code of conduct for discussants who want to resolve their disputes reasonably by way of a critical discussion. (shrink)

This article proposes a way of connecting two levels at which scholars have studied discursive practices from a normative perspective: on the one hand, local transactions-face-to-face arguments or dialogues-and broadly dispersed public debates on the other. To help focus my analysis, I select two representatives of work at these two levels: the pragmadialectical model of critical discussion and Habermas's discourse theory of politicallegal deliberation. The two models confront complementary challenges that arise from gaps between their prescriptions and contexts of actual (...) discourse. In response, I propose a theory of argument cogency that distinguishes three kinds of merit: content, transactional, and public. Normative links between the two levels arise through the ways argument contents spread across multiple transactions in a social space whose structure and composition favor collective reasonableness.

'What exactly is knowledge?' The Theaetetus is a seminal text in the philosophy of knowledge, and is acknowledged as one of Plato's finest works. Cast as a conversation between Socrates and a clever but modest student, Theaetetus, it explores one of the key issues in philosophy: what is knowledge? Though no definite answer is reached, the discussion is penetrating and wide-ranging, covering the claims of perception to be knowledge, the theory that all is in motion, and the perennially tempting idea (...) that knowledge and truth are relative to different individuals or states. The inquirers go on to explore the connection between knowledge and true judgement, and the famous threefold definition of knowledge as justified true belief. Packed with subtle arguments, the dialogue is also a work of literary genius, with an unforgettable portrait of Socrates as a midwife of wisdom. This new edition uses the acclaimed translation by John McDowell. It includes a valuable introduction that locates the work in Plato's oeuvre, and explains some of the competing interpretations of its overall meaning. The notes elucidate Plato's arguments and draw connections within the work and with other philosophical discussions. ABOUT THE SERIES: For over 100 years Oxford World's Classics has made available the widest range of literature from around the globe.

Dialectical approaches traditionally conceptualize argumentation as a discussion in which two parties debate on “two sides of an issue”. However, many political issues engender multiple positions. This is clear in multi-party online deliberations in which often an array of competing positions is debated in one and the same discussion. A proponent of a given position thus addresses a number of possible opponents, who in turn may hold incompatible opinions. The goal of this paper is to shed extra light on such (...) “polylogical” clash of opinions in online deliberation, by examining the multi-layered participation in actual online debates. The examples are drawn from the readers’ discussions on Osama bin Laden’s killing in online versions of two British newspapers: The Guardian and The Telegraph. As a result of the analysis, a distinction between sides, positions, and cases in argumentative deliberation is proposed. (shrink)

Dialectical fallacies are typically defined as breaches of the rules of a regulated discussion between two participants. What if discussions become more complex and involve multiple parties with distinct positions to argue for? Are there distinct argumentation norms of polylogues? If so, can their violations be conceptualized as polylogical fallacies? I will argue for such an approach and analyze two candidates for argumentative breaches of multi-party rationality: false dilemma and collateral straw man.

Seneca in his Moral Epistles to Lucilium ridicules Protagoras’ claim that both sides of any position can be equally well argued. Cicero, on the contrary, in the surviving fragments of his dialogue, the Republic, maintains in the person of Laelius that the thorough exploration of the strengths and weaknesses of any position pro and con is the best and often the only dialectical avenue to the discovery of difficult truths. There are therefore at least two sides to the issue of (...) whether philosophers ought to address their arguments to the two sides of any issue. This paper examines the epistemic advantages and disadvantages of the same reasoning agent playing both roles of advocate and critic, as opposed to encouraging only distinct independently minded reasoning agents each to consider any of the opposing sides of an issue in dispute. The question in argumentation theory posed by this inquiry in simplest terms is whether a single thinker considering both sides of an issue is more able to arrive at truth, or whether, as the popular adage has it, two minds are inherently dialectically better than one. The answer proposed here is that it does not matter provided that the conflict of opposing views are in some manner resolved with the sincere intention of arriving at the truth. (shrink)

Normative pragmatics can bridge the differences between dialectical and rhetorical theories in a way that saves the central insights of both. Normative pragmatics calls attention to how the manifest strategic design of a message produces interpretive effects and interactional consequences. Argumentative analysis of messages should begin with the manifest persuasive rationale they communicate. But not all persuasive inducements should be treated as arguments. Arguments express with a special pragmatic force propositions where those propositions stand in particular inferential relations to one (...) another. Normative pragmatics provides a framework within which varieties of propositional inference and pragmatic force may be kept straight. Normative pragmatics conceptualizes argumentative effectiveness in a way that integrates notions of rhetorical strategy and rhetorical situation with dialectical norms and procedures for reasonable deliberation. Strategic effectiveness should be seen in terms of maximizing the chances that claims and arguments will be reasonably evaluated, whether or not they are accepted. Procedural rationality should be seen in terms of adjustment to the demands of concrete circumstances. Two types of adjustment are illustrated: rhetorical strategies for framing the conditions for dialectical deliberation and rhetorical strategies for making do with limitations to dialectical deliberation.

In normative pragmatics, a kind of empirical discourse analysis organized by normative theory, the analysis of any communication process begins with an idealized model of the discourse that can be compared with actual practices. Idealizations of argumentation can be found, among other places, in theoretical descriptions of ‘critical discussion’ and other dialogue types. Comparing ideal models with actual practices can pinpoint defects in the models (leading to theoretical refinements), but it can also identify deficiencies in practice. This latter possibility invites (...) redesign around well-justified idealizations. This paper outlines an approach to the design of discourse processes and illustrates the approach with contrastive analysis of several recently developed protocols for discussion and debate on the worldwide web.

A specific issue for argumentation theory is whether information and communication technologies play any role in governing argument — that is, as parties engage in practical activities across space and time via ICTs, does technology matter for the interplay of argumentative content and process in managing disagreement? The case made here is that technologies do matter because they are not merely conduits of communication but have a role in the pragmatics of communication and argumentation. In particular, ICTs should be recognized (...) as communication-information services that are delegated degrees of responsibility for managing disagreements arising from practical activities. These services are organized around practical theories for designing disagreement space. However, recognizing this relationship between argument and technology requires accounting for procedures, techniques, or rules and speech acts that are not argumentative propositions in any strict sense but that are consequential for what becomes argumentation in any setting. An account about designing disagreement space, grounded in Jackson and Jacobs’s theory of Disagreement Management, is put forward to address these issues while more generally contributing to understanding argument in context.

I want to discuss them, first, to show how they acknowledge in exemplary fashion a pair of challenges I think we should all be (...) addressing; and next to consider their specific responses.

This article challenges the view that rhetoric, dialectic and logic are three perspectives on argument, relating respectively to its process, its procedure, and its product. It also questions the view that rhetorical arguments represent a distinctive type. It suggests that, as related to argument, rhetoric is the theory of arguments in speeches, dialectics the theory of arguments in conversations, and logic the theory of good reasoning in each.
