Argumentation as the public exchange of reasons is widely thought to enhance deliberative interactions that generate and justify reasonable public policies. Adopting an argumentation-theoretic perspective, we survey the norms that should govern public argumentation and address some of the complexities that scholarly treatments have identified. Our focus is on norms associated with the ideals of correctness and participation as sources of a politically legitimate deliberative outcome. In principle, both ideals are mutually coherent. If the information needed for a correct deliberative (...) outcome is distributed among agents, then maximising participation increases information diversity. But both ideals can also be in tension. If participants lack competence or are prone to biases, a correct deliberative outcome requires limiting participation. The central question for public argumentation, therefore, is how to strike a balance between both ideals. Rather than advocating a preferred normative framework, our main purpose is to illustrate the complexity of this theme. (shrink)

In this paper, we use a pseudo-algorithmic procedure for assessing an AI-generated text. We apply the Comprehensive Assessment Procedure for Natural Argumentation (CAPNA) in evaluating the arguments produced by an Artificial Intelligence text generator, GPT-3, in an opinion piece written for the Guardian newspaper. The CAPNA examines instances of argumentation in three aspects: their Process, Reasoning and Expression. Initial Analysis is conducted using the Argument Type Identification Procedure (ATIP) to establish, firstly, that an argument is present and, secondly, its specific (...) type in terms of the argument classification framework of the Periodic Table of Arguments (PTA). Procedural Questions are then used to test the acceptability of the argument in each of the three aspects. The analysis shows that while the arguments put forward by the AI text generator are varied in terms of their type and follow familiar patterns of human reasoning, they contain obvious weaknesses. From this we can conclude that the automated generation of persuasive, well-reasoned argumentation is a far more difficult task than the generation of meaningful language, and that if AI systems producing arguments are to be persuasive, they require a method of checking the plausibility of their own output.

In this paper, we formulate a procedure for assessing reasoning as it is expressed in natural arguments. The procedure is a specification of one of the three aspects of argumentation assessment distinguished in the Comprehensive Assessment Procedure for Natural Argumentation that makes use of the argument categorisation framework of the Periodic Table of Arguments. The theoretical framework and practical application of both the CAPNA and the PTA are described, as well as the evaluation procedure that combines the two. The procedure (...) is illustrated through an evaluation of the reasoning of two example arguments from a recently published text. (shrink)

In this paper I describe the apparent differences between the views of Mizrahi and Seidel on the strength of arguments from expert opinion. I show that most of Seidel's objections rely on an understanding of the words 'expert' and 'opinion' different from those which Mizrahi employs. I also discuss certain inconsistencies found in both papers over the use of these key terms. The paper concludes by noting that Mizrahi is right to suggest that evidence shows expert predictions to be unreliable, (...) but Seidel is correct to observe that this finding should not be used to claim that expert opinion in general is not to be trusted.

As more and more sophisticated software is created to allow the mining of arguments from natural language texts, this paper sets out to examine the suitability of the well-established and readily available methods of corpus linguistics to the study of argumentation. After brief introductions to corpus linguistics and the concept of meta-argument, I describe three pilot-studies into the use of the terms Straw man, Ad hominem, and Slippery slope, made using the open access News on the Web corpus. The presence (...) of each of these phrases on internet news sites was investigated and assessed for correspondence to the norms of use by argumentation theorists. All three pilot-studies revealed interesting facts about the usage of the terms by non-specialists, and led to numerous examples of the types of arguments mentioned. This suggests such corpora may be of use in two different ways: firstly, the wider project of improving public debate and educating the populace in the skills of critical thinking can only be helped by a better understanding of the current state of knowledge of the technical terms and concepts of argumentation. Secondly, theorists could obtain a more accurate picture of how arguments are used, by whom, and to what reception, allowing claims on such matters to be evidence, rather than intuition, based.

ABSTRACTIn order to properly understand how expert disagreement should be dealt with, it is essential to grasp how expert opinion is used in the reasoning process by which humans reach conclusions and make decisions. This paper utilises the tools of argumentation theory, specifically Douglas Walton’s argument schemes, and variations upon them, in order to examine how patterns of reasoning are affected by the presence of conflicting testimony. This study suggests that although it may be supplemented with the construction of epistemic (...) hierarchies, the scheme of reasoning for the appeal to expert opinion provides no mechanism for establishing a preference for one expert statement over another, making it impossible to reach any rational conclusion as to the likely truth of the matter. Further, it is also argued that other schemes for presumptive argumentation are either unhelpful in themselves or lead to unwanted consequences. (shrink)

Conceptual Engineering, the practice of stipulating a change in the meaning of a word in order to improve it in some fashion, for some end, has proved a popular topic among philosophers of language in recent times. Deutsch (Philos Stud 177:3935–3957, 2020) has argued that it has received an undue degree of interest since its implementation falls onto one of the horns of a dilemma: either the change to be effected is in the global semantic meaning of the given word/concept, (...) in which case it is infeasible, or it is merely in the local speaker-meaning, in which case it is largely trivial. I suggest, however, that there is a deeper, more troubling, objection to Conceptual Engineering. My criticism does not strictly take the form of a dilemma, since some cases may fall upon both horns at once and others may be able to squeeze through the gap, but it does involve highlighting two potential weaknesses of the project: one of those, as with Deutsch, is the danger of triviality, although it is not concerned only with the division between semantic and speaker meaning. It seems clear that there are cases where a particular authority or legislature has the capacity to alter a word’s legal meaning; others where certain groups may discuss the best way to use a technical term, each putting forward their preferred suggestions; and individual speakers are at liberty to choose to use a word with a particular intention. None of this is new, nor controversial, and, thus, is largely trivial. In all cases, but particularly where meanings are manipulated without due authority, inexplicitly, or in order to further a particular theoretical conception, however, there is a strong chance that the engineer will be led to commit one of the fallacies of language to which philosophy is particularly vulnerable (Hinton Evaluating the language of argument, Springer, Cham, 2021). These include fallacies of vagueness, equivocation, and persuasive definition. In this paper, I use examples to illustrate the likely fallaciousness of conceptual redefinitions and highlight in particular the ‘Philosophical Fallacy’, outlined by Nelson (A theory of philosophical fallacies.Translated by Leal F, Carus D. Springer, Cham 2016). I conclude that, as a method for philosophers, Conceptual Engineering is, in broad terms, either trivial or fallacious. (shrink)

The purpose of this paper is twofold: to give a good account of the argument from ignorance, with a presumptive argumentation scheme, and to raise issues on the work of Walton, the nature of abduction and the concept of epistemic closure. First, I offer a brief disambiguation of how the terms 'argument from ignorance' and 'argumentum ad ignorantiam' are used. Second, I show how attempts to embellish this form of reasoning by Douglas Walton and A.J. Kreider have been unnecessary and (...) unhelpful. Lastly, I offer a full and effective account of the argument from ignorance and discuss the lessons of the analysis.Le but de cet article est double: donner un bon compte rendu de l'argument par l'ignorance, avec un schème d'argumentation présomptif, et soulever des questions sur certains aspects de l’œuvre de Walton, la nature des raisonnements abductifs et le concept de fermeture épistémique. Premièrement, j'offre une brève désambiguïsation de la façon dont les termes «argument par l'ignorance» et «argumentum ad ignorantiam» sont utilisés. Deuxièmement, je montre comment les tentatives de Douglas Walton et de A.J. Kreider d'embellir cette forme de raisonnement ont été ni nécessaires et ni utiles. Enfin, j'offre un compte-rendu complet et utile de l'argument par l'ignorance et je discute des leçons de l'analyse. (shrink)

This paper begins with an assessment of the origin of the term ‘deep disagreement’ to reflect fundamental differences in argument procedure and suggests an alternative explanation of such stalemates that may apply in many cases and does lead to a possible resolution strategy, through discussion of the ordering of certain principles, rather than their acceptance or rejection. Similarities are then drawn with disputes which are supported by conflicting expert opinions and I lay out the advantages of seeking to resolve them (...) through the construction of an epistemic hierarchy. It is noted that while such hierarchies may not be easy to build, and are certainly not fool-proof, their importance is in the provision of a mechanism by which an apparently stalled debate can move forward, leading to a better understanding of the conflicting positions, if not full resolution.

The aim of this paper is to illustrate where previous attempts at the characterisation of Slippery Slope Arguments (SSAs) have gone wrong, and to provide an analysis which better captures their true nature. The first part describes Walton’s [10] arguments in support of his views on SSAs and also considers the characterisations put forward by other researchers. All of these are found wanting due to their failure to capture the essence of the slippery slope and their inability to distinguish SSAs (...) from other consequentialist forms of argument. The second part puts forward a clearer analysis of what is special about SSAs and proposes an argumentation scheme which allows them to be easily distinguished from other arguments from consequences.

Herein, I consider arguments resting on an appeal to a non-existent authority as a species of argument from authority, and ultimately show them to be reliant on arguments from analogy in their inferential force. Three sub-types of argument are discussed: from authorities as yet unborn, no longer living, or incapable of ever doing so. In each case it is shown that an element of arguing from analogy is required since there can be no direct evidence of any assertions of the (...) source. In conclusion, it is suggested that such steps of analogy are employed frequently in traditional arguments from authority. (shrink)

In this paper, I consider a number of philosophical critiques of language and describe how their criticisms compare. In particular, I discuss how the current trend in the philosophy of language known as conceptual engineering fits into this tradition and to what extent it can be considered a critique of language per se, rather than a method of addressing dissatisfactions with certain individual terms. I suggest that criticisms can be divided allegations of two types of shortcoming: dangers and deficiencies. In (...) the category of dangers, I consider some well-known examples from the history of philosophy, and suggest that they partly rely on an unexpressed from of Linguistic Determinism. I then move on to the deficiencies highlighted in the critiques offered by Wittgenstein in the Tractatus Logico-Philosophicus, and Mauthner in his Contributions to a Critique of Language. These form a pair of apparently opposite ways of considering the flaws in language, but I shall argue that they have much in common. I then describe the conceptual engineering movement and its mission to provide ‘improved’ meanings of certain terms. I show that implicit in the assumptions behind conceptual engineering are criticisms of language of both varieties – current meanings are seen as dangerous as they represent a threat to social justice, and the system of allocation of meaning is seen as flawed and in need of external intervention.

Arguments may sometimes be advanced with a non-standard function. One such function, it is suggested, is the expression of identity, a practice which may play a significant role in political representation. This paper sets out to examine a number of short addresses given at the High-Level segment of the Cop26 conference, which are considered to contain instances of such argumentation. Their content is analysed and evaluated by means of the Comprehensive Assessment Procedure for Natural Argumentation (CAPNA), and an attempt is (...) made to highlight the purposes of the delegates in addressing the conference. At a more fundamental level, the goal of this work is to assess the possibility of identifying arguments as being meant largely as statements of identity or representation, and the suitability of the CAPNA or other norm-based systems for evaluating such discourse. The speakers studied include representatives from OPEC, the Trade Unions, and the leaders of Vietnam and Liechtenstein. Ultimately, the study concludes that while further work is necessary both on understanding the relationship between argument and identity in the political arena, and on the application of argument norms to representational discourse, evaluations of this kind are meaningful and informative.

I then go on to introduce the works which contribute to this spe-cial issue and explain how they assist in the fulfilment of my hopes.

In September 2018, the ArgDiaP association, along with colleagues from Germany and the UK, organised one of the longest and most interdisciplinary series of events ever dedicated to argumentation - Warsaw Argumentation Week, WAW 2018. The eleven-day ‘week’ featured a five day graduate school on computational and linguistic perspectives on argumentation (3rd SSA school); five workshops: on systems and algorithms for formal argumentation (2nd SAFA), argumentation in relation to society (1st ArgSoc), philosophical approaches to argumentation (1st ArgPhil), legal argumentation (2ndMET-ARG) (...) and argumentation in rhetoric (1st MET-RhET); and two conferences: on computational models of argumentation (7th COMMA conference) and on argumentation and corpus linguistics (16th ArgDiaP conference). WAW hosted twelve tutorials and eight invited talks as well as welcoming over 130 participants. All the conferences and workshops publish pre- or post-proceedings in the top journals and book series in the field. (shrink)
