Any well-structured argumentative exchange must be preceded by some preparatory stages. In the pragma-dialectical four-stage model of critical discussion, the clarification of issues and positions is relegated to the confrontation stage and the other preparatory matters are dealt within the opening stage. In the opening stage, the parties involved come to agree to discuss their differences and to do so by an argumentative exchange rather than by, say, a sequence of bids and offers. They should also come to agree on (...) the rules of dialogue, on roles, on logical principles, on types of argument, and on the propositions that can be used as basic premises. All in all, a lot of work needs to be done before the first topical argument can be put forward. Especially the opening stage seems prone to further disagreements and protracted discussions, e.g., about the admissibility of particular kinds of argument or particular basic premises. There is also the problem that a successful opening stage threatens to settle matters beforehand and thus put the argumentation stage out of business. The paper suggests some measures that could alleviate the workload of the opening stage, without making the argumentation stage otiose. (shrink)

Argumentative discussion is successful only if, at the concluding stage, both parties can agree about the result of their enterprise. If they can not, the whole discussion threatens to start all over again. Dialectical ruling should prevent this from happening. The paper investigates whether dialectical rules may enforce a decision one way or the other; either by recognizing some arguments as conclusive or some criticisms as devastating. At the end the pragma-dialectical model appears more successful than even its protagonists have (...) claimed. (shrink)

This paper makes an independent start with formalizing the rules for the argumentation stage of critical discussions. It does not deal with the well-known code of conduct consisting of ten rules but with the system consisting of fifteen rules on which the code of conduct is based. The rules of this system are scrutinized and problems they raise are discussed. Then a formal dialectical system is defined that reflects most of the contents of these rules. The aim is to elucidate (...) the way the rules work and to show how a formal approach can be useful to achieve this. It is also shown how the present method can be used to study the nature of circular argumentation. While, generally, the formalization follows closely the original rules for the argumentation stage of critical discussions, there will also be proposed some modifications of the original protocol.

In many contexts a retraction of commitment isfrowned upon. For instance, it is not appreciated,generally, if one withdraws a promise or denies anearlier statement. Critical discussion, too, caneasily be disrupted by retractions, if these occur toofrequently and at critical points. But on the otherhand, the very goal of critical discussion –resolution of a dispute – involves a retraction,either of doubt, or of some expressed point of view.A person who never retracts, not even under pressureof cogent arguments, would hardly qualify as (...) areasonable discussant. Also, inconsistencies in one'sposition, once they have been pointed out, must bedealt with by some kind of retraction. The problem ofretraction is to find a suitable model of dialoguethat allows retractions where they seem reasonable, oreven required, and rules them out (or puts sanctionsupon them) whenever they would become disruptive of awell-organized process of dialogue.The present paper tries to point to a solution basedon the following principles: (1) Retraction rulesdetermine what retractions are permissible, and (2) ifpermissible what the consequences of retraction are.(3) Retraction rules vary according to the type ofdialogue and (4) according to the type of commitmentretracted. For instance, assertions and mereconcessions need to be distinguished, as well aslight-side and dark-side commitments. (5) To accountfor our contradictory intuitions on the issue ofretractions, one may best resort to a complex type ofdialogue in which different retraction rules hold fordifferent parts.The paper explains, summarizes, and expands upon thediscussion of retraction in Commitment inDialogue by Douglas Walton and the present author(cf. Walton and Krabbe 1995). (shrink)

We shall investigate the similarities and dissimilarities between old and new dialectic. For the ‘old dialectic’, we base our survey mainly on Aristotle’s Topics and Sophistical Refutations, whereas for the ‘new dialectic’, we turn to contemporary views on dialogical interaction, such as can, for the greater part, be found in Walton’s The New Dialectic. Three issues are taken up: types of dialogue, fallacies, and strategies. Though one should not belittle the differences in scope and outlook that obtain between the old (...) and the new dialectic, the paper will show that in many respects the old dialectic foreshadows the new dialectic.

The book revives the neutral monism of Mach, James, and Russell and applies the updated view to the problem of redefining physicalism, explaining the origins of sensation, and the problem of deriving extended physical objects and systems from an ontology of events.

Criticism may degenerate into quibbling or nitpicking. How can discussants keep quibblers under control? In the paper we investigate cases in which a battle about words replaces a discussion of the matters that are actually at issue as well as cases in which a battle about minor objections replaces a discussion of the major issues. We survey some lines of discussion dealing with these situations in profiles of dialogue.

A look at Mach's contributions to psychology in historical context and his elimination of metaphysical problems (in psychology).

Empirical Logic and Public Debate supplies a large number of previously unpublished papers that together make up a survey of recent developments in the field of empirical logic. It contains theoretical contributions, some of a more formal and some of an informal nature, as well as numerous contemporary and historical case studies. The book will therefore be attractive both to those who wish to focus upon the theory and practice of discussion, debate, arguing, and argument, as well as to those (...) readers who are primarily interested in applications to a particular field, such as ethics, political philosophy, feminist philosophy, or the history of philosophy.

This paper discusses several types of relevance criticism within dialogue. Relevance criticism is a way one could or should criticize one's partner's contribution in a conversation as being deficient in respect of conversational coherence. The first section tries to narrow down the scope of the subject to manageable proportions. Attention is given to the distinction between criticism of alleged fallacies within dialogue and such criticism as pertains to argumentative texts. Within dialogue one may distigguish tenability criticism, connection criticism, and narrow-type (...) relevance criticism. Only the last of these three types of criticism constitutes a charge of fallacy and carries with it a burden of proof. In the second it is observed that a full study of narrow-type relevance criticism would require the construction of complicated, many-layered, dialogue systems. Such a study can, however, be profitably preceded by setting up profiles of dialogue that help us discuss the ins and outs of certain types of move. This is illustrated with an example. (shrink)

Bertrand Russell claimed in the Analysis of Matter that physics is purely structural or relational and so leaves out intrinsic properties of matter, properties that, he said, are evident to us at least in one case: as the internal states of our brains. Russell's hypothesis has figured in recent discussions of physicalism and the mind body problem, by Chalmers, Strawson and Stoljar, among others, but I want to reject two popular interpretations: 1. a conception of intrinsic properties of matter as (...) categorical properties and 2. a fallacious line of descent argument that attributes pan-psychist or proto-experientialist properties to matter by analogy with human minds. Instead, I think Russell's hypothesis points us toward 1. a doctrine of concretely instantiated dispositions in matter and 2. selectively instantiated relations. (shrink)

Aristotle's illustrations of the fallacy of Figure of Speech (or Form of Expression) are none too convincing. They are tied to Aristotle's theory of categories and to peculiarities of Greek grammar that fail to hold appeal for a contemporary readership. Yet, upon closer inspection, Figure of Speech shows many points of contact with views and problems that inhabit 20th-century analytical philosophy. In the paper, some Aristotelian examples will be analyzed to gain a better understanding of this fallacy. The case of (...) the Third Man argument and some modern cases lend plausibility to the claim that Figure of Speech is of more interest as a type of fallacy than has generally been assumed. Finally, a case is made for the view that Figure of Speech, though listed among the fallacies dependent upon language, is not properly classified as a fallacy of ambiguity. More likely, it should be looked upon as a type of non sequitur. This has important consequences for the profile of dialogue associated with this fallacy. (shrink)

Sometimes pernicious circularities appear in definitions of fundamental concepts of argumentation theory. For instance, in pragma-dialectical theory, the concept of a fallacy and that of a critical discussion aiming at resolving a difference of opinion mutually presuppose one another. A similar relationship obtains, in argumentation theory at large, between the concept of argumentation and that of rationality. Again, the concept of an argumentative dialogue presupposes a concept of statement. Yet, statementhood is sometimes claimed to be determined by a locution’s function (...) in dialogue. Similarly, for the concepts of proof and argument. Are these circularities really objectionable? Are they resolvable? If they are not, how can we live with them? It will be argued that some of these problems can be neglected some of the time, but not all of them all of the time. Though there may be no royal road towards resolution, several strategies can be applied. But sometimes patience is what is needed. (shrink)

Systems of formal dialectics articulate methods of conflict resolution. To this end they provide norms to regulate verbal exchanges between the Proponent of a thesis and an Opponent. These regulated exchanges constitute what are known as formal discussions.One may ask what moves, if any, in formal discusions correspond to arguing for or against the thesis. It is claimed that certain moves of the Proponent's are properly designated as arguing for the thesis, and that certain moves of the Opponent purport to (...) criticize the tenability or the relevance of the reasons advanced. Thus the usefulness of formal dialectic systems as models for reasonable argument is vindicated.It is then proposed to make these systems more realistic by incorporating in them a norm of Creative Reasoning that removes the severe restrictions to which the Proponent's arguing was hitherto subject. As a consequence, a certain type of irrelevant reason is no longer automatically excluded. Therefore, it is proposed to extend the Opponent's rights to exert relevance criticism. The new dialectic systems are shown to be strategically equivalent to the original ones. Finally, it is stressed that the Opponent's criticism should not be designated as arguing against the thesis. The Opponent criticizes, but does not argue. (shrink)

A full appreciation for Ernst Mach's doctrine of the economy of thought must take account of his direct realism about particulars (elements) and his anti-realism about space-time laws as economical constructions. After a review of thought economy, its critics and some contemporary forms, the paper turns to the philosophical roots of Mach's doctrine. Mach claimed that the simplest, most parsimonious theories economized memory and effort by using abstract concepts and laws instead of attending to the details of each individual event (...) or experiment. For Mach, the individual case never truly repeated in all of its uniqueness, nor was all of the individual detail of a physical element adequately captured in abstract laws and schemata, however necessary these were for the pursuit of science. As can be shown from specific passages, some already published, some not, Mach's elements included physical qualia in nature similar to Russell's unsensed sensibilia, which existed even where there were no conscious observers. An argument will be presented to make the case that Mach believed in the mind-independent elements from the 1870s on, while other aspects of his thought evolved over time; I have thus dated the references to reflect this historical progression. I concentrate on Mach's ontology, as it bears on economy of thought, not his epistemology per se, which might well have been restricted to observable elements/sensations. After his own conversion to neutral monism, in the 1920s, Bertrand Russell echoed Mach's call for a 'future science' capable of handling the 'intrinsic character' of qualitative data directly without the excessive abstraction of physics.

The purpose of this paper is to briefly describe and compare the original goals and perspectives of both rhetoric and dialectic in theory and in practice. Dialectic is the practice and theory of conversations; rhetoric that of speeches. For theory of dialectic, this paper will turn to Aristotle's Topics and Sophistical Refutations; for theory of rhetoric, to his Rhetoric. Thus it will appear that rhetoric and dialectic are pretty close. Yet, on the other hand, there is a long tradition of (...) mutual antagonism. The paper tries to summarize the common features of, as well as the differences between, the two. To get a taste of both dialectic and rhetoric in practice the reader is invited to enter the House of Callias, as we know it from Plato's Protagoras. After this visit there remains no doubt that rhetoric and dialectic are intertwined on the level of practice. Moreover, we may look forward to their integration on the level of theory. (shrink)

This paper explores applications of concepts from argumentation theory to mathematical proofs. Note is taken of the various contexts in which proofs occur and of the various objectives they may serve. Examples of strategic maneuvering are discussed when surveying, in proofs, the four stages of argumentation distinguished by pragma-dialectics. Derailments of strategies (fallacies) are seen to encompass more than logical fallacies and to occur both in alleged proofs that are completely out of bounds and in alleged proofs that are at (...) least mathematical arguments. These considerations lead to a dialectical and rhetorical view of proofs. (shrink)

Neutral monism is a position in metaphysics defended by Mach, James, and Russell in the early twentieth century. It holds that minds and physical objects are essentially two different orderings of the same underlying neutral elements of nature. This paper sets out some of the central concepts, theses and the historical background of ideas that inform this doctrine of elements. The discussion begins with the classic neutral monism of Mach, James, and Russell in the first part of the paper, then (...) considers recent neo-Russellian versions in the second half. The chances for a revival of neutral monism are probably slight; its key ideas and starting points lie far from those in contemporary philosophy of mind. A better route might be through the philosophy of science and a deeper understanding of causation. (shrink)

The situationally disqualifying ad hominem attack is an argumentative move in critical dialogue whereby one participant points out certain features in his adversary's personal situation that are claimed to make it inappropriate for this adversary to take a particular point of view, to argue in a particular way, or to launch certain criticisms. In this paper, we discuss some examples of this way of arguing. Other types of ad hominem argumentation are discussed as well and compared with the situationally disqualifying (...) type. The socalled Houtlosser Dilemma highlights the danger of unconditionally condoning ad hominem arguments. We propose a classification of ad hominem, and a more restrictive use of the term 'circumstantial'. Finally, we discuss whether ad hominem arguments are (always?) to be rejected as fallacious.

This paper attempts to systematically characterize critical reactions in argumentative discourse, such as objections, critical questions, rebuttals, refutations, counterarguments, and fallacy charges, in order to contribute to the dialogical approach to argumentation. We shall make use of four parameters to characterize distinct types of critical reaction. First, a critical reaction has a focus, for example on the standpoint, or on another part of an argument. Second, critical reactions appeal to some kind of norm, argumentative or other. Third, they each have (...) a particular illocutionary force, which may include that of giving strategic advice to the other. Fourth, a critical reaction occurs at a particular level of dialogue (the ground level or some meta-level). The concepts here developed shall be applied to discussions of critical reactions by Aristotle and by some contemporary authors. (shrink)

Inconsistent Commitments and Commitment to Inconsistencies.

Grete Hermann’s essay “Die naturphilosophischen Grundlagen der Quantenmechanik” has received much deserved scholarly attention in recent years. In this paper, I follow the lead of Elise Crull who sees in Hermann’s work the general outlines of a neo-Kantian interpretation of quantum theory. In full support of this view, I focus on Hermann’s central claim that limited spatio-temporal, and even analogically causal, representations of events exist within an overall relational structure of entangled quantum mechanical states that defy any unified spatio-temporal description. (...) In my view, Hermann also advances an important transcendental argument that perspectival spatio-temporal representations of nature have their foundations in general relational networks that are not spatio-temporal. The key point is that the adoption of a perspectival system within the general network induces the representation but only for that context. These ideas are consistent with a perspectival subject–object principle in Kant and also with Weyl’s work on Lie groups and their representations. (shrink)

Should we regard Jennifer Lackey’s ‘Creationist Teacher’ as understanding evolution, even though she does not, given her religious convictions, believe its central claims? We think this question raises a range of important and unexplored questions about the relationship between understanding, factivity and belief. Our aim will be to diagnose this case in a principled way, and in doing so, to make some progress toward appreciating what objectual understanding—i.e., understanding a subject matter or body of information—demands of us. Here is the (...) plan. After some ground clearing in §1, §2 outlines and motivates a plausible working model—moderate factivity—for characterising the sense in which objectual understanding should be regarded as factive. §3 shows how the datum that we can understand false theories can, despite initial suggestions to the contrary, be assimilated straightforwardly within the moderate factivity model. §4 highlights how the inverse kind of case to that explored in §3—viz., a variant of Lackey’s creationist teacher case—poses special problems for moderate factivity. With reference to recent work on moral understanding by Hills, §5 proposes a solution to the problem, and §6 attempts to diagnose why it is that we might originally have been led to draw the wrong conclusion.

A look at the dynamical concept of space and space-generating processes to be found in Kant, J.F. Herbart and the mathematician Bernhard Riemann's philosophical writings.

Formal dialectic has its roots in ancient dialectic. We can trace this influence in Charles Hamblin’s book on fallacies, in which he introduced his first formal dialectical systems. Earlier, Paul Lorenzen proposed systems of dialogical logic, which were in fact formal dialectical systems avant la lettre, with roles similar to those of the Greek Questioner and Answerer. In order to make a comparison between ancient dialectic and contemporary formal dialectic, I shall formalize part of the Aristotelian procedure for Academic debates. (...) The resulting system will be compared (1) with Van Eemeren and Grootendorst’s system of rules of Critical Discussion (the pragma-dialectical discussion procedure), which must, however, first itself be reconstructed as a formal dialectical system, and (2) with a Hamblin-type system, and (3) a Lorenzen-type system. When drawing comparisons, it will become clear that there is a line to be drawn from Aristotle to formal dialectic and pragma-dialectics, extending to contemporary computational models of argument.

Extension is probably the most general natural property. Is it a fundamental property? Leibniz claimed the answer was no, and that the structureless intuition of extension concealed more fundamental properties and relations. This paper follows Leibniz's program through Herbart and Riemann to Grassmann and uses Grassmann's algebra of points to build up levels of extensions algebraically. Finally, the connection between extension and measurement is considered.

What if in discussion the critic refuses to recognize an emotionally expressed argument of her interlocutor as an argument, accusing him of having presented no argument at all. In this paper, we shall deal with this reproach, which taken literally amounts to a charge of having committed a fallacy of non-argumentation. As such it is a very strong, if not the ultimate, criticism, which even carries the risk of abandonment of the discussion and can, therefore, not be made without burdening (...) oneself with correspondingly strong obligations. We want to specify the fallacies of non-argumentation and their dialectic, i.e., the proper way to criticize them, the appropriate ways for the arguer to react to such criticism, and the appropriate ways for the critic to follow up on these reactions. Among the types of fallacy of non-argumentation, the emphasis will be on the appeal to popular sentiments. Our aim is to reach, for cases of non-argumentation, a survey of dialectical possibilities. By making the disputants themselves responsible for the place of emotion in their dialogues, we hope to contribute to a further development of the theory of dialectical obligations. (shrink)
