This two-volume collection showcases a wide range of modern approaches to the philosophical study of language. Contributions illustrate how these strands of research are interconnected and show the importance of such a broad outlook. The aim is to throw light upon some of the key questions in language and communication and also to inspire, inform, and integrate a community of researchers in philosophical linguistics. Volume one concentrates on fundamental theoretical topics. This means considering vital questions about what languages are and (...) how they relate to reality, and describing some of the key areas of thought in linguistics and the philosophy of language. Contributors also discuss how philosophy influences related fields such as translation, pragmatics, and argumentation. (shrink)

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)

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.

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.

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)

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.

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)

The disjunctive theory of perception claims that we should understand statements about how things appear to a perceiver to be equivalent to statements of a disjunction that either one is perceiving such and such or one is suffering an illusion (or hallucination); and that such statements are not to be viewed as introducing a report of a distinctive mental event or state common to these various disjoint situations. When Michael Hinton first introduced the idea, he suggested that the burden (...) of proof or disproof lay with his opponent, that what was needed was to show that our talk of how things look or appear to one..

Abstract Contemporary egalitarians often appeal to a distinction between inequalities issuing from choice as opposed to those stemming from brute luck. Inequalities of the second kind, they say, ought to be redressed, while those of the former may be allowed to stand. In this paper, I scrutinize the role played by the notion of brute luck in Ronald Dworkin's theory of equality. My intention is to show that Dworkin seeks to occupy what turns out to be an untenable middle position. (...) He is sandwiched unhappily between G. A. Cohen's radical brute luck egalitarianism, on the one side, and a non-egalitarian conception of justice that rejects entirely the appeal to brute luck, on the other. It follows from the untenable nature of Dworkin's position that egalitarians face a much starker choice than he realizes. They should either wholeheartedly embrace the brute luck story or else find another way of grounding their position. (shrink)

The mystery of existence and our place in that mystery--as expressed in a single Chinese landscape painting: a new work of meditative philosophy by the renowned translator of the Chinese classics and author of Hunger Mountain. Join David Hinton, the premier modern translator of the Chinese classics, as he stands before a single landscape painting, discovering in it the wondrous story of existence—and as part of that story, the magical nature of consciousness. What he coaxes from the image is (...) nothing less than a revelation: the dynamic interweaving of mind and Cosmos, and the glorious dance of Absence and Presence that is the secret of that Cosmos. The painting called Peaceful-Distance Pavilion by Shih-t'ao (1642-1707) is, like other paintings in that genre, mostly space: one tiny figure, accompanied by an attendant, looks out over a vast landscape of mountains and clouds. But start looking into that space and, with the right guidance, what you end up seeing is profound. David Hinton is the perfect guide. He uses his knowledge of Chinese philosophy, poetry, art, language, and writing system to illuminate this painting's message, which is ultimately the story of the glorious dance between nothing and everything, between emptiness and existence. It's an enthralling journey that can change the way you look at the world, a journey for which David is a wise and eloquent guide. (shrink)

Let the fact of the separateness of persons be that we are separate individuals, each with his or her own life to lead. This is to be distinguished from the doctrine of the separateness of persons: the claim that the fact of our separateness is especially deep and important, morally speaking. In this paper, I argue that we ought to reject this doctrine. I focus most of my attention on the suggestion that the separateness of persons best explains the importance (...) we attach to moral rights. After criticizing Nozick's use of the doctrine, I formulate an alternative account of the significance of rights. I then show how proponents of the doctrine of separateness have no principled way of distinguishing between egoism and moral libertarianism. I suggest that rejecting the doctrine of our separateness for the reasons I propose ensures that we need have no fear of having to embrace consequentialism as a result. (shrink)

A new translation of one of the great koan collections--by the premier translator of the Chinese classics--that reveals it to be a literary and philosophical masterwork beyond its association with Chan/Zen. Zen is famous for its koans, those seemingly confounding statements, questions, or stories that masters use to gauge their students' practice. Here, the lauded modern master of Chinese poetry translation asks us to reimagine one of the greatest of the koan collections in a new way: as a classic of (...) Chinese philosophical literature in the tradition of the Tao Te Ching or the Chuang Tzu. He presents the No-Gate Gateway (variously also familiar to readers as the Mumonkan, Wu-men Kuan, Gateless Gate, or Gateless Barrier), in a "bare bones" version, without the usual additional commentary, not intended to be studied in the usual case-by-case method, but to be read as a complete work in itself, one that leads the reader carefully on a path to the discovery of the deep nature of reality--an unconventional way of reading it that can be truly revelatory.

Michael Otsuka sets out to vindicate left-libertarianism, a political philosophy which combines stringent rights of control over one's own mind, body, and life with egalitarian rights of ownership of the world. Otsuka reclaims the ideas of John Locke from the libertarian Right, and shows how his Second Treatise of Government provides the theoretical foundations for a left-libertarianism which is both more libertarian and more egalitarian than the Kantian liberal theories of John Rawls and Thomas Nagel. Otsuka's libertarianism is founded on (...) a right of self-ownership. Here he is at one with 'right-wing' libertarians, such as Robert Nozick, in endorsing the highly anti-paternalistic and anti-moralistic implications of this right. But he parts company with these libertarians in so far as he argues that such a right is compatible with a fully egalitarian principle of equal opportunity for welfare. In embracing this principle, his own version of left-libertarianism is more strongly egalitarian than others which are currently well known. Otsuka argues that an account of legitimate political authority based upon the free consent of each is strengthened by the adoption of such an egalitarian principle. He defends a pluralistic, decentralized ideal of political society as a confederation of voluntary associations. Part I of Libertarianism without Inequality concerns the natural rights of property in oneself and the world. Part II considers the natural rights of punishment and self-defence that form the basis for the government's authority to legislate and punish. Part III explores the nature and limits of the powers of governments which are created by the consensual transfer of the natural rights of the governed. Libertarianism without Inequality is a book which everyone interested in political theory should read. (shrink)

DCPS is a connectionist production system interpreter that uses distributed representations. As a connectionist model it consists of many simple, richly interconnected neuron‐like computing units that cooperate to solve problems in parallel. One motivation for constructing DCPS was to demonstrate that connectionist models are capable of representing and using explicit rules. A second motivation was to show how “coarse coding” or “distributed representations” can be used to construct a working memory that requires far fewer units than the number of different (...) facts that can potentially be stored. The simulation we present is intended as a detailed demonstration of the feasibility of certain ideas and should not be viewed as a full implementation of production systems. Our current model only has a few of the many interesting emergent properties that we eventually hope to demonstrate: It is damage‐resistant, it performs matching and variable binding by massively parallel constraint satisfaction, and the capacity of its working memory is dependent on the similarity of the items being stored.

A long-standing theme in discussion of perception and thought has been that our primary cognitive contact with individual objects and events in the world derives from our perceptual contact with them. When I look at a duck in front of me, I am not merely presented with the fact that there is at least one duck in the area, rather I seem to be presented withthisthing (as one might put it from my perspective) in front of me, which looks to (...) me to be a duck. Furthermore, such a perception would seem to put me in a position not merely to make the existential judgment that there is some duck or other present, but rather to make a singular, demonstrative judgment, that that is a duck. My grounds for an existential judgment in this case derives from my apprehension of the demonstrative thought and not vice versa. (shrink)

This paper examines the role that attention to emotions around climate change can play for third sector climate change engagement initiatives, an area to which the literature on such initiatives has paid little attention. It focuses on Carbon Conversations, a programme that explicitly acknowledges the role of difficult emotions and underlying values in people's engagement with climate change. While there are limitations to this approach, results show that it can help certain audiences engage more deeply with issues around climate change (...) and carbon reduction. Important lessons can be drawn for other initiatives that aim to engage the public on climate change. (shrink)

Is it OK to lie to Siri? Is it bad to mistreat a robot for our own pleasure? Under what condition should we grant a moral status to an artificial intelligence (AI) system? This paper looks at different arguments for granting moral status to an AI system: the idea of indirect duties, the relational argument, the argument from intelligence, the arguments from life and information, and the argument from sentience. In each but the last case, we find unresolved issues with (...) the particular argument, which leads us to move to a different one. We leave the idea of indirect duties aside since these duties do not imply considering an AI system for its own sake. The paper rejects the relational argument and the argument from intelligence. The argument from life may lead us to grant a moral status to an AI system, but only in a weak sense. Sentience, by contrast, is a strong argument for the moral status of an AI system—based, among other things, on the Aristotelian principle of equality: that same cases should be treated in the same way. The paper points out, however, that no AI system is sentient given the current level of technological development. (shrink)

Over the past three decades, the philosophy of biology has emerged from the shadow of the philosophy of physics to become a respectable and thriving philosophical subdiscipline. The authors take a fresh look at the life sciences and the philosophy of biology from a strictly realist and emergentist-naturalist perspective. They outline a unified and science-oriented philosophical framework that enables the clarification of many foundational and philosophical issues in biology. This book will be of interest both to life scientists and philosophers.

We provide a battery of examples of delusions against which theoretical accounts can be tested. Then, we identify neuropsychological anomalies that could produce the unusual experiences that may lead, in turn, to the delusions in our battery. However, we argue against Maher’s view that delusions are false beliefs that arise as normal responses to anomalous experiences. We propose, instead, that a second factor is required to account for the transition from unusual experience to delusional belief. The second factor in the (...) aetiology of delusions can be described superficially as a loss of the ability to reject a candidate for belief on the grounds of its implausibility and its inconsistency with everything else that the patient knows. But we point out some problems that confront any attempt to say more about the nature of this second factor. (shrink)

What exactly is hope and how does it influence our decisions? In How We Hope, Adrienne Martin presents a novel account of hope, the motivational resources it presupposes, and its function in our practical lives. She contends that hoping for an outcome means treating certain feelings, plans, and imaginings as justified, and that hope thereby involves sophisticated reflective and conceptual capacities. Martin develops this original perspective on hope--what she calls the "incorporation analysis"--in contrast to the two dominant philosophical (...) conceptions of hope: the orthodox definition, where hoping for an outcome is simply desiring it while thinking it possible, and agent-centered views, where hoping for an outcome is setting oneself to pursue it. In exploring how hope influences our decisions, she establishes that it is not always a positive motivational force and can render us complacent. She also examines the relationship between hope and faith, both religious and secular, and identifies a previously unnoted form of hope: normative or interpersonal hope. When we place normative hope in people, we relate to them as responsible agents and aspire for them to overcome challenges arising from situation or character. Demonstrating that hope merits rigorous philosophical investigation, both in its own right and in virtue of what it reveals about the nature of human emotion and motivation, How We Hope offers an original, sustained look at a largely neglected topic in philosophy.

A ‘lottery belief’ is a belief that a particular ticket has lost a large, fair lottery, based on nothing more than the odds against it winning. The lottery paradox brings out a tension between the idea that lottery beliefs are justified and the idea that that one can always justifiably believe the deductive consequences of things that one justifiably believes – what is sometimes called the principle of closure. Many philosophers have treated the lottery paradox as an argument against the (...) second idea – but I make a case here that it is the first idea that should be given up. As I shall show, there are a number of independent arguments for denying that lottery beliefs are justified. (shrink)
