O objetivo deste trabalho é desafiar as correntes tradicionais da bioética, que fundamentam ideais abstratos de imparcialidade, cidadania universal e autonomia absoluta; confrontá-los a partir do conhecimento situado e do reconhecimento da matriz de dominação interseccional vigente na América Latina. Procura investigar como transformar múltiplas desigualdades, repolitizando a justiça interseccional, a agência política em momentos críticos de progresso e colonização dos nossos bens comuns. Nossa proposta final é uma bioética crítica interseccional, representativa e participativa, que inclua de forma não subordinada (...) as vozes e os conhecimentos dos outros, focada em nossas necessidades regionais, promovendo nossa autonomia relacional e o cuidado com a vida, em e para nossos territórios, comunidades e as gerações futuras.

A ideia da primeira parte deste e-book surgiu durante a disciplina de Tópicos Especiais em Políticas Linguísticas ministrada por mim no Programa de Pós-Graduação em Estudos de Linguagens (PPGEL) da Faculdade de Artes Letras de Comunicação (FAALC) da Universidade Federal de Mato Grosso do Sul (UFMS) durante o segundo semestre de 2023. A segunda parte da obra surgiu de afinidades teóricas e metodológicas entre as professoras do curso de Letras da UFMS (Campo Grande) que orientam os capítulos 7, 8 e (...) 9 e traz diferentes questões relacionadas ao ensino de línguas. [...] Por fim, espero que esta obra possa contribuir para ampliar e qualificar as reflexões acerca das temáticas aqui levantadas e que possa suscitar novas propostas de pesquisa ou de intervenção no ensino de línguas e nas Políticas Linguísticas.

This paper analyzes selected examples of uses of argumentation tactics that exploit emotive language, many of them criticized as deceptive and even fallacious by classical and recent sources, including current informal logic textbooks. The analysis is based on six argumentation schemes, and an account of the dialectical setting in which these schemes are used. The three conclusions are (1) that such uses of emotive language are often reasonable and necessary in argumentation based on values, (2) but that they are defeasible, (...) and hence need to be seen as open to critical questioning (3) and that when they are used fallaciously, it is because they interfere with critical questioning or conceal the need for it. The analysis furnishes criteria for distinguishing between arguments based on the use of emotive words that are reasonable tools of persuasion, and those that are fallacious tactics used to conceal and distort information.

This paper argues for a reinterpretation of Aristotle's concept of an enthymeme and also his wider informal logic in terms of arguments that are defeasible. They are represented by forms of argument that are called argumentation schemes, considered to be similar to forms of argument found in deductive logic, but different from the foregoing in virtue of their being defeasible. Indeed, the most interesting schemes have been put forward as a helpful way of characterizing structures of human reasoning that have (...) proved troublesome to model deductively. The paper sheds new light on Aristotle's topics and how to dene `enthymeme'. If the traditional denition of an enthymeme in logic accepted for over two thousand years is a misnomer, the question is raised whether we ought to redene it as a defeasible argumentations scheme or leave things as they are.

In this chapter, I investigate the imaginary boundary between the actual world and fictional gameworlds by focusing on videogame situations in which this fourth wall is foregrounded or broken. For this purpose, I first define the videogame experience as a self-involving, interactive fiction experience, based on Kendall Walton’s account of fiction (1990). I then describe how, in the current academic discourse on games, it is often claimed that the concept of fourth wall breaks cannot be applied to videogames due (...) to their inherent interactivity. Within game studies, the consensus seems to be that the boundaries between the real and the fictional world are always already blurred in videogame experiences. This chapter instead shows how using interactive, digital technologies to represent fictional worlds does not necessarily complicate the conceptualization of the fourth wall, but rather reveals new ways in which it can be broken. More precisely, this chapter discusses how appreciators of videogames can not only actively participate in fourth wall breaks, but are also uniquely able to initiate these breaks themselves. -/- .

Kendall Walton argues that photographs, like mirrors and microscopes, meet sufficient conditions to be considered a kind of prosthesis for seeing. Well aware of the controversiality of this claim, he offers three criteria for perception met by photographs like other perceptual aids which makes them transparent –that is, we see through them.1(II) Jonathan Cohen and Aaron Meskin attempt to refute the transparency thesis by arguing that photographs cannot be genuine prostheses for seeing because they fail to meet another necessary (...) condition, namely that of egocentric spatial information (ESI). Only devices that belong to a process type that carries ESI are, in principle, genuine prostheses for seeing.2 (III) I will offer a two- part refutation of the proposed disqualification of photographs by 1) offering an example of a case where another instance of the process-type to which photographs belong carries ESI, establishing the reliability of the process type that allegedly precluded photographs from qualifying (IV) and 2) offering another example to illustrate how photographs can meet the ESI condition.

Las soluciones a la paradoja de la ficción propuestas por Kendall Walton y Gregory Currie, a pesar de diferir en puntos de detalle importantes, suponen dos movimientos conceptuales comunes para entender la situación de quien está inmerso en una obra de ficción, a través del recurso a la noción de “cuasi-emociones” y de la idea de construcción de escenarios imaginarios. Aquí propondré que sus propuestas fallan en sus dos puntos centrales, a partir de problemas que son, sin embargo, independientes. (...) Por un lado, sus ideas sobre las emociones que sentimos al estar atrapados por una obra de ficción fallan al suponer una versión inaceptable de la tesis cognitivista acerca de las emociones. Por otro, sus ideas sobre la construcción de mundos imaginarios por parte de los “consumidores de ficción” fallan al suponer una dicotomía entre mundos de ficción y realidad. Finalmente, discutiré brevemente el modo en que ambos tipos de problemas repercuten sobre la viabilidad del planteo de la paradoja misma. (shrink)

Kendall Walton explains pictures in terms of games of perceptual make-believe. Pictures or depictions are props that draw us to participate in games of make-believe where we imagine seeing what a picture depicts. Walton proposes that one imagines of one’s perceptual experience of the coloured canvas that it is a different perceptual experience. The issue is whether perception and imagination can combine the way Walton suggests. Can one imagine a perception to be different? To get a clearer (...) understanding of the unified perceptual-imaginative experience Walton posits, the paper turns to competing theories that explain perceptual experience in terms of contents, relations to objects, or both contents and relations. Walton appeals to theories of perceptual content and cognitive penetration. But it is also important to examine whether his view fits with recent theories that explain perception only in terms of relations or in terms of both contents and relations. The paper argues that Walton’s view is compatible with content theories of perception and can be defended from some objection once we look at the detail these theories offer. Walton’s view is not compatible with pure relational theories of perception but it can be explained by hybrid content-relational theories of perception that posit de re senses. (shrink)

The aim of this article is to present the disagreement between Moran and Walton on the nature of our affective responses to fiction and to defend a view on the issue which is opposed to Moran’s account and improves on Walton’s. Moran takes imagination-based affective responses to be instances of genuine emotion and treats them as episodes with an emotional attitude towards their contents. I argue against the existence of such attitudes, and that the affective element of such (...) responses should rather be taken to be part of what is imagined. In this respect, I follow Walton; and I also agree with the latter that our affective responses to fiction are, as a consequence, not instances of real emotion. However, this gives rise to the challenge to be more specific about the nature of our responses and explain how they can still involve a phenomenologically salient affective element, given that propositionally imagining that one feels a certain emotion is ruled out because it may be done in a dispassionate way. The answer —already suggested, but not properly spelled out by Walton— is that affectively responding to some fictional element consists in imaginatively re-presenting an experience of emotional feeling towards it. The central thought is that the conscious and imaginative representation of the affective character of an instance of genuine emotion itself involves the respective phenomenologically salient affective element, despite not instantiating it.

This paper proposes an argumentation-based procedure for legal interpretation, by reinterpreting the traditional canons of textual interpretation in terms of argumentation schemes, which are then classified, formalized, and represented through argument visualization and evaluation tools. The problem of statutory interpretation is framed as one of weighing contested interpretations as pro and con arguments. The paper builds an interpretation procedure by formulating a set of argumentation schemes that can be used to comparatively evaluate the types of arguments used in cases of (...) contested statutory interpretation in law. A simplified version of the Carneades Argumentation System is applied in a case analysis showing how the procedure works. A logical model for statutory interpretation is finally presented, covering pro-tanto and all-things-considered interpretive conclusions. (shrink)

The aim of the paper is to present a typology of argument schemes. In first place, we found it helpful to define what an argument scheme is. Since many argument schemes found in contemporary theories stem from the ancient tradition, we took in consideration classical and medieval dialectical studies and their relation with argumentation theory. This overview on the main works on topics and schemes provides a summary of the main principles of classification. In the second section, Walton’s theory (...) is briefly explained to introduce the schemes classification and its different levels. At least, the final part shows the main application of the schemes in computing and AI. -/- . (shrink)

This chapter proposes a dialectical approach to legal interpretation, consisting of three dimensions: a formalization of the canons of interpretation in terms of argumentation schemes; a dialectical classification of interpretive schemes; and a logical and computational model for comparing the arguments pro and contra an interpretation. The traditional interpretive maxims or canons used in both common and civil law are translated into defeasible patterns of arguments, which can be evaluated through sets of corresponding critical questions. These interpretive argumentation schemes are (...) classified in general categories and a distinction is drawn between schemes supporting and rebutting an interpretation. This framework allows conceiving statutory interpretation as a dialectical procedure consisting in weighing arguments pro and contra an interpretation. This procedure is formalized and represented computationally through tools from formal argumentation systems. (shrink)

This paper explains the importance of classifying argumentation schemes, and outlines how schemes are being used in current research in artificial intelligence and computational linguistics on argument mining. It provides a survey of the literature on scheme classification. What are so far generally taken to represent a set of the most widely useful defeasible argumentation schemes are surveyed and explained systematically, including some that are difficult to classify. A new classification system covering these centrally important schemes is built.

Understanding everyday behavior relies heavily upon understanding our ability to improvise, how we are able to continuously anticipate and adapt in order to coordinate with our environment and others. Here we consider the ability of musicians to improvise, where they must spontaneously coordinate their actions with co-performers in order to produce novel musical expressions. Investigations of this behavior have traditionally focused on describing the organization of cognitive structures. The focus, here, however, is on the ability of the time-evolving patterns of (...) inter-musician movement coordination as revealed by the mathematical tools of complex dynamical systems to provide a new understanding of what potentiates the novelty of spontaneous musical action. We demonstrate this approach through the application of cross wavelet spectral analysis, which isolates the strength and patterning of the behavioral coordination that occurs between improvising musicians across a range of nested time-scales. Revealing the sophistication of the previously unexplored dynamics of movement coordination between improvising musicians is an important step towards understanding how creative musical expressions emerge from the spontaneous coordination of multiple musical bodies.

Statutory interpretation involves the reconstruction of the meaning of a legal statement when it cannot be considered as accepted or granted. This phenomenon needs to be considered not only from the legal and linguistic perspective, but also from the argumentative one - which focuses on the strategies for defending a controversial or doubtful viewpoint. This book draws upon linguistics, legal theory, computing, and dialectics to present an argumentation-based approach to statutory interpretation. By translating and summarizing the existing legal interpretative canons (...) into eleven patterns of natural arguments - called argumentation schemes - the authors offer a system of argumentation strategies for developing, defending, assessing, and attacking an interpretation. Illustrated through major cases from both common and civil law, this methodology is summarized in diagrams and maps for application to computer sciences. These visuals help make the structures, strategies, and vulnerabilities of legal reasoning accessible to both legal professionals and laypeople. (shrink)

This paper uses argument diagrams, argumentation schemes, and some tools from formal argumentation systems developed in artificial intelligence to build a graph-theoretic model of relevance shown to be applicable as a practical method for helping a third party judge issues of relevance or irrelevance of an argument in real examples. Examples used to illustrate how the method works are drawn from disputes about relevance in natural language discourse, including a criminal trial and a parliamentary debate.

I propose a way of understanding empathy on which it does not necessarily involve any-thing like thinking oneself into another’s shoes, or any imagining at all. Briefly, the empa-thizer uses an aspect of her own mental state as a sample, expressed by means of a phenomenal concept, to understand the other person. This account does a better job of explaining the connection between empathetic experiences and the objects of empathy than most traditional ones do. And it helps to clarify the (...) relations among different varieties of empathy and empathy-like experiences, including empathy with fictional characters. -/- . (shrink)

Using tools like argument diagrams and profiles of dialogue, this paper studies a number of examples of everyday conversational argumentation where determination of relevance and irrelevance can be assisted by means of adopting a new dialectical approach. According to the new dialectical theory, dialogue types are normative frameworks with specific goals and rules that can be applied to conversational argumentation. In this paper is shown how such dialectical models of reasonable argumentation can be applied to a determination of whether an (...) argument in a specific case is relevant are not in these examples. The approach is based on a linguistic account of dialogue and text from congruity theory, and on the notion of a dialectical shift. Such a shift occurs where an argument starts out as fitting into one type of dialogue, but then it only continues to makes sense as a coherent argument if it is taken to be a part of a different type of dialogue.

A problem for dialogue models of argumentation is to specify a set of conditions under which an opponent’s claims, offered in support of a standpoint under dispute, ought to be challenged. This project is related to the issue of providing a set of acceptability conditions for claims made in a dialogue. In this paper, we consider the conditions of suspicion and trust articulated by Jacobs (Alta, 2003), arguing that neither are acceptable as general conditions for challenge. We propose a third (...) condition that attempts to mark a middle ground between suspicion and trust. (shrink)

Religious disagreement is an emerging topic of interest in social epistemology. Little is known about how philosophers react to religious disagreements in a professional context, or how they think one should respond to disagreement. This paper presents results of an empirical study on religious disagreement among philosophers. Results indicate that personal religious beliefs, philosophical training, and recent changes in religious outlook have a significant impact on philosophers' assessments of religious disagreement. They regard peer disagreement about religion as common, and most (...) surveyed participants assume one should accord weight to the other's opinion. Theists and agnostics are less likely to assume they are in a better epistemic position than their interlocutors about religious questions compared with atheists, but this pattern only holds for participants who are not philosophers of religion. Continental philosophers think religious beliefs are more like preferences than analytic philosophers, who regard religious beliefs as fact-like. (shrink)

Speculative fiction, such as science fiction and fantasy, has a unique epistemic value. We examine similarities and differences between speculative fiction and philosophical thought experiments in terms of how they are cognitively processed. They are similar in their reliance on mental prospection, but dissimilar in that fiction is better able to draw in readers (transportation) and elicit emotional responses. By its use of longer, emotionally poignant narratives and seemingly irrelevant details, speculative fiction allows for a better appraisal of the consequences (...) of philosophical ideas than thought experiments.

This article analyses the fallacy of wrenching from context, using the dialectical notions of commitment and implicature as tools. The data, a set of key examples, is used to sharpen the conceptual borderlines around the related fallacies of straw man, accent, misquotation, and neglect of qualifications. According to the analysis, the main characteristics of wrenching from context are the manipulation of the meaning of the other’s statement through devices such as the use of misquotations, selective quotations, and quoting out of (...) context. The theoretical tools employed in the analysis are pragmatic theories of meaning and a dialectical model of commitment, used to explain how and why a standpoint is distorted. The analysis is based on a conception of fallacies as deceptive strategic moves in a game of dialogue. As a consequence, our focus is not only on misquotations as distortions of meaning, but on how they are used as dialectical tools to attack an opponent or win a dispute. Wrenching from context is described as a fallacy of unfairly attributing a commitment to another party that he never held. Its power as a deceptive argumentation tactic is based on complex mechanisms of implicit commitments and on their misemployment to improperly suggest an attribution of commitment. (shrink)

In this paper we analyze the uses and misuses of argumentation schemes from verbal classification, and show how argument from definition supports argumentation based on argument from verbal classification. The inquiry has inevitably included the broader study of the concept of definition. The paper presents the schemes for argument from classification and for argument from definition, and shows how the latter type of argument so typically supports the former. The problem of analyzing arguments based on classification is framed in a (...) structure that reveals the crucial role it plays in the persuasion process. The survey of the literature includes the work of Hastings, Perelman, Kienpointner and Schiappa, but still finds much of value in Aristotle. Lessons drawn from Aristotle’s Topics are shown to be useful for developing new tools for assessing definitions and arguments from definition. (shrink)

Value Sensitive Design (VSD) is an established method for integrating values into technical design. It has been applied to different technologies and, more recently, to artificial intelligence (AI). We argue that AI poses a number of challenges specific to VSD that require a somewhat modified VSD approach. Machine learning (ML), in particular, poses two challenges. First, humans may not understand how an AI system learns certain things. This requires paying attention to values such as transparency, explicability, and accountability. Second, ML (...) may lead to AI systems adapting in ways that ‘disembody’ the values embedded in them. To address this, we propose a threefold modified VSD approach: 1) integrating a known set of VSD principles (AI4SG) as design norms from which more specific design requirements can be derived; 2) distinguishing between values that are promoted and respected by the design to ensure outcomes that not only do no harm but also contribute to good; and 3) extending the VSD process to encompass the whole life cycle of an AI technology in order to monitor unintended value consequences and redesign as needed. We illustrate our VSD for AI approach with an example use case of a SARS-CoV-2 contact tracing app. (shrink)

With the advent of the semantic web, the problem of ambiguity is becoming more and more urging. Semantic analysis is necessary for explaining and resolving some sorts of ambiguity by inquiring into the relation between possibilities of predication and definition of a concept in order to solve problems such as interpretation and ambiguity. If computing is now approaching such problems of linguistic analysis, what is worth inquiring into is how the development of linguistic studies can be useful for developing the (...) theoretical background of ontologies. Our proposal is to develop a theory of definition alternative to the traditional metaphysical approach and the modern relativistic account. We interpret the ancient notion of essential definition in a dialectical perspective, and show how the dialectical definition by genus and difference corresponds to the semantic analysis of the definiendum. The dialectical definition is shown to be grounded on the deepest endoxa (shared knowledge) of a community, and to be the argumentatively strongest definition. After presenting the most common types of definition used in argumentation, the linguistic and logical characteristics of the notion of definition by genus and difference are set out in a pragmatic framework.

Depression is vastly heterogeneous in its symptoms, neuroimaging data, and treatment responses. As such, describing how it develops at the network level has been notoriously difficult. In an attempt to overcome this issue, a theoretical “negative prediction mechanism” is proposed. Here, eight key brain regions are connected in a transient, state-dependent, core network of pathological communication that could facilitate the development of depressive cognition. In the context of predictive processing, it is suggested that this mechanism is activated as a response (...) to negative/adverse stimuli in the external and/or internal environment that exceed a vulnerable individual’s capacity for cognitive appraisal. Specifically, repeated activation across this network is proposed to update an individual’s brain so that it increasingly predicts and reinforces negative experiences over time—pushing an individual at-risk for or suffering from depression deeper into mental illness. Within this, the negative prediction mechanism is poised to explain various aspects of prognostic outcome, describing how depression might ebb and flow over multiple timescales in a dynamically changing, complex environment.

Hume was a cognitive scientist of religion avant la lettre. His Natural History of Religion (1757 [2007]) locates the origins of religion in human nature. This paper explores similarities between some of his ideas and the cognitive science of religion, the multidisciplinary study of the psychological origins of religious beliefs. It also considers Hume’s distinction between two questions about religion: its foundation in reason (the domain of natural theology and philosophy of religion) and its origin in human nature (the domain (...) of cognitive science of religion).

Defenders of moral perception have famously argued that seeing value is relevantly similar to seeing color. Some critics think, however, that the analogy between color-seeing and value-seeing breaks down in several crucial respects. Defenders of moral perception, these critics say, have not succeeded in providing examples of non-moral perception that are relevantly analogous to cases of moral perception. Therefore, it can be doubted whether there is such a thing as moral perception at all. I argue that, although the analogy between (...) color perception and moral perception does indeed break down in several crucial respects, that conclusion does not weaken the case of defenders of moral perception, because better analogies are available. If defenders of moral perception seek to draw support from an analogy, then seeing emotion will protect them better against criticisms than will seeing color. (shrink)

Manipulation of quotation, shown to be a common tactic of argumentation in this paper, is associated with fallacies like wrenching from context, hasty generalization, equivocation, accent, the straw man fallacy, and ad hominem arguments. Several examples are presented from everyday speech, legislative debates and trials. Analysis using dialog models explains the critical defects of argumentation illustrated in each of the examples. In the formal dialog system CB, a proponent and respondent take turns in making moves in an orderly goal-directed sequence (...) of argumentation in which the proponent tries to persuade the respondent to become committed to a conclusion by asking questions and offering arguments. Analyzing quotation by using the notion of commitment in dialog, it is shown (a) how an arguer’s previous assertions can be brought to light in the course of a dialog to deal with problems arising from misquotation, (b) how the profile of dialog model allows a critic to analyse the fundamental effects misquotation brings about in a dialog, and (c) how the critic can use such an analysis to correct the problem.

Many virtual communities that rely on user-generated content (such as social news sites, citizen journals, and encyclopedias in particular) offer unrestricted and immediate ‘write access’ to every contributor. It is argued that these communities do not just assume that the trust granted by that policy is well-placed; they have developed extensive mechanisms that underpin the trust involved (‘backgrounding’). These target contributors (stipulating legal terms of use and developing etiquette, both underscored by sanctions) as well as the contents contributed by them (...) (patrolling for illegal and/or vandalist content, variously performed by humans and bots; voting schemes). Backgrounding trust is argued to be important since it facilitates the avoidance of bureaucratic measures that may easily cause unrest among community members and chase them away. (shrink)

In this paper, we introduce an enactive account of loving as participatory sense-making inspired by the “I love to you” of the feminist philosopher Luce Irigaray. Emancipating from the fusionist concept of romantic love, which understands love as unity, we conceptualise loving as an existential engagement in a dialectic of encounter, in continuous processes of becoming-in-relation. In these processes, desire acquires a certain prominence as the need to know (the other, the relation, oneself) more. We build on Irigaray’s account of (...) love to present a phenomenology of loving interactions and then our enactive account. Finally, we draw some implications for ethics. These concern language, difference, vulnerability, desire, and self-transformation. (shrink)

The paper considers contemporary models of presumption in terms of their ability to contribute to a working theory of presumption for argumentation. Beginning with the Whatelian model, we consider its contemporary developments and alternatives, as proposed by Sidgwick, Kauffeld, Cronkhite, Rescher, Walton, Freeman, Ullmann-Margalit, and Hansen. Based on these accounts, we present a picture of presumptions characterized by their nature, function, foundation and force. On our account, presumption is a modal status that is attached to a claim and has (...) the effect of shifting, in a dialogue, a burden of proof set at a local level. Presumptions can be analysed and evaluated inferentially as components of rule-based structures. Presumptions are defeasible, and the force of a presumption is a function of its normative foundation. This picture seeks to provide a framework to guide the development of specific theories of presumption. (shrink)

This book analyzes the uses of emotive language and redefinitions from pragmatic, dialectical, epistemic and rhetorical perspectives, investigating the relationship between emotions, persuasion and meaning, and focusing on the implicit dimension of the use of a word and its dialectical effects.

Information is a central notion for cognitive sciences and neurosciences, but there is no agreement on what it means for a cognitive system to acquire information about its surroundings. In this paper, we approximate three influential views on information: the one at play in ecological psychology, which is sometimes called information for action; the notion of information as covariance as developed by some enactivists, and the idea of information as minimization of uncertainty as presented by Shannon. Our main thesis is (...) that information for action can be construed as covariant information, and that learning to perceive covariant information is a matter of minimizing uncertainty through skilled performance. We argue that the agent’s cognitive system conveys information for acting in an environment by minimizing uncertainty about how to achieve her intended goals in that environment. We conclude by reviewing empirical findings that support our view and by showing how direct learning, seen as instance of ecological rationality at work, is how mere possibilities for action are turned into embodied know-how. Finally, we indicate the affinity between direct learning and sense-making activity. (shrink)

This paper investigates agents’ blameworthiness when they are part of a group that does harm. We analyse three factors that affect the scope of an agent’s blameworthiness in these cases: shared intentionality, interpersonal influence, and common knowledge. Each factor involves circumstantial luck. The more each factor is present, the greater is the scope of each agent’s vicarious blameworthiness for the other agents’ contributions to the harm. We then consider an agent’s degree of blameworthiness, as distinct from her scope of blameworthiness. (...) We suggest that an agent mostly controls her degree of blameworthiness—but even here, luck constrains what possible degrees of blameworthiness are open to her. (shrink)

The paper uses two historical examples, public health (1840-1880) and town planning (1945-1975) in Britain, to analyse the challenges faced by goal-driven research, an increasingly important trend in science policy, as exemplified by the prominence of calls for addressing Grand Challenges. Two key points are argued. (1) Given that the aim of research addressing social or global problems is to contribute to improving things, this research should include all the steps necessary to bring science and technology to fruition. This need (...) is captured by the idea of practical integration, which brings this type of research under the umbrella of collective practical reason rather than under the aegis of science. Achieving practical integration is difficult for many reasons: the complexity of social needs, the plurality of values at stake, the limitation of our knowledge, the elusive nature of the skills needed to deal with uncertainty, incomplete information and asymmetries of power. Nevertheless, drawing from the lessons of the case studies, it is argued that (2) practical integration needs a proper balance between values, institutions and knowledge: i.e. a combination of mutual support and mutual limitation. Pursuing such a balance provides a flexible strategy for approximating practical integration. (shrink)

Argumentation schemes can be described as abstract structures representing the most generic types of argument, constituting the building blocks of the ones used in everyday reasoning. This paper investigates the structure, classification, and uses of such schemes. Three goals are pursued: 1) to describe the schemes, showing how they evolved and how they have been classified in the traditional and the modern theories; 2) to propose a method for classifying them based on ancient and modern developments; and 3) to outline (...) and show how schemes can be used to describe and analyze or produce real arguments. To this purpose, we will build on the traditional distinctions for building a dichotomic classification of schemes, and we will advance a modular approach to argument analysis, in which different argumentation schemes are combined together in order to represent each step of reasoning on which a complex argument relies. Finally, we will show how schemes are applied to formal systems, focusing on their applications to Artificial Intelligence, AI & Law, argument mining, and formal ontologies. (shrink)

The occasion for this dialogue on Elisabeth Anscombe’s legacy for twenty-first-century ethics came with the publication in Italian of the collection of her ethical writings (G. E. M. Anscombe, Scritti di etica con un saggio di Peter Geach, a cura di S. Cremaschi, Morcelliana, Brescia 2022). In addition to making Anscombe’s ethical writings accessible to the Italian public, the book brings together her contribution to practical philosophy to its full extent for the first time. Vaccarezza's essay discusses Anscombe’s critique of (...) the modern law-based view of ethics. Magri’s contribution focuses on Anscombe’s anti-anti-naturalism, aiming to unearth the twofold agenda in her project of meta-critique of modern moral philosophy. De Anna's paper sets out to examine the role of Wittgensteinian ways of thinking in Anscombe’s proposed restructuring of modern ethics. (shrink)

In this paper, we use concepts, structure and tools from argumentation theory to show how conversational implicatures are triggered by conflicts of presumptions. Presumptive implicatures are shown to be based on defeasible forms of inference used in conditions of lack of knowledge, including analogical reasoning, inference to the best explanation, practical reasoning, appeal to pity, and argument from cause. Such inferences are modelled as communicative strategies to knowledge gaps that shift the burden of providing the missing contrary evidence to the (...) other party in a dialogue. Through a series of illustrative examples, we show how such principles of inference are based on common knowledge about the ordinary course of events shared by participants in a structured dialogue setting in which they take turns putting forward and responding to speech acts.

English - language Wikipedia is constantly being plagued by vandalistic contributions on a massive scale. In order to fight them its volunteer contributors deploy an array of software tools and autonomous bots. After an analysis of their functioning and the ‘ coactivity ’ in use between humans and bots, this research ‘ discloses ’ the moral issues that emerge from the combined patrolling by humans and bots. Administrators provide the stronger tools only to trusted users, thereby creating a new hierarchical (...) layer. Further, surveillance exhibits several troubling features : questionable profiling practices, the use of the controversial measure of reputation, ‘ oversurveillance ’ where quantity trumps quality, and a prospective loss of the required moral skills whenever bots take over from humans. The most troubling aspect, though, is that Wikipedia has become a Janus - faced institution. One face is the basic platform of MediaWiki software, transparent to all. Its other face is the anti - vandalism system, which, in contrast, is opaque to the average user, in particular as a result of the algorithms and neural networks in use. Finally it is argued that this secrecy impedes a much needed discussion to unfold ; a discussion that should focus on a ‘ rebalancing ’ of the anti - vandalism system and the development of more ethical information practices towards contributors.

Robert Kimball, in “What’s Wrong with ArgumentumAd Baculum?” (Argumentation, 2006) argues that dialogue-based models of rational argumentation do not satisfactorily account for what is objectionable about more malicious uses of threats encountered in some ad baculum arguments. We review the dialogue-based approach to argumentum ad baculum, and show how it can offer more than Kimball thinks for analyzing such threat arguments and ad baculum fallacies.

Prop oriented make-believe is make-believe utilized for the purpose of understanding what I call “props,” actual objects or states of affairs that make propositions “fictional,” true in the make-believe world. I, David Hills, and others have claimed that prop oriented make-believe lies at the heart of the functioning of many metaphors, and one variety of fictionalism in metaphysics invokes prop oriented make-believe to explain away apparent references to entities some find questionable or problematic (fictional characters, propositions, moral properties, numbers). Elisabeth (...) Camp has argued against my and David Hills’ views of metaphor. Her arguments, many of them echoed by Catharine Wearing, demolish a very implausible account of metaphor, but leave entirely untouched the views that Hills and I actually proposed. Clarifying what we say about metaphor serves also as a defense of fictionalist theories that invoke prop oriented make-believe. (shrink)

An interesting question is whether deflationism about truth (and falsity) extends to related properties and relations on truthbearers. Lionel Shapiro (2011) answers affirmatively by arguing that a certain deflationism about truth is as plausible as an analogous version of deflationism about logical consequence. I argue that the argument fails on two counts. First, it trivializes to any relation between truthbearers, including substantive ones; in other words, his argument can be used to establish that deflationism about truth is as plausible as (...) deflationism about an arbitrary sentential relation. Second, the alleged analogy between the arguments for deflationism about truth and deflationism about consequence fails. Along the way I consider what implications the failure of the equiplausibility thesis has for deflationism about falsity. (shrink)

An ancient argument attributed to the philosopher Carneades is presented that raises critical questions about the concept of an all-virtuous Divine being. The argument is based on the premises that virtue involves overcoming pains and dangers, and that only a being that can suffer or be destroyed is one for whom there are pains and dangers. The conclusion is that an all-virtuous Divine (perfect) being cannot exist. After presenting this argument, reconstructed from sources in Sextus Empiricus and Cicero, this paper (...) goes on to model it as a deductively valid sequence of reasoning. The paper also discusses whet her the premises are true. Questions about the possibility and value of proving and disproving the existence of God by logical reasoning are raised, as well as ethical questions about how the cardinal ethical virtues should be defined.

Ambiguity occurs insofar as a reasoner lacks information about the relevant physical probabilities. There are objections to the application of standard Bayesian inductive logic and decision theory in contexts of significant ambiguity. A variety of alternative frameworks for reasoning under ambiguity have been proposed. Two of the most prominent are Imprecise Bayesianism and Dempster–Shafer theory. We compare these inductive logics with respect to the Ambiguity Dilemma, which is a problem that has been raised for Imprecise Bayesianism. We develop an agent-based (...) model comparison that isolates the difference between the two inductive logics in their updating methods. We find that Dempster–Shafer theory does not avoid the Ambiguity Dilemma. We discuss the implications of this result. (shrink)

This special issue on what some regard as a crisis of replicability in cognitive science (i.e. the observation that a worryingly large proportion of experimental results across a number of areas cannot be reliably replicated) is informed by three recent developments. -/- First, philosophers of mind and cognitive science rely increasingly on empirical research, mainly in the psychological sciences, to back up their claims. This trend has been noticeable since the 1960s (see Knobe, 2015). This development has allowed philosophers to (...) draw on a wider range of relevant resources, but it also makes them vulnerable to relying on claims that may not survive further scrutiny. If we have reasons to believe that a large proportion of findings in the psychological sciences cannot be reliably replicated, this would be a problem for philosophers who use such findings in their work. Second, philosophers are increasingly designing and carrying out their own experiments to back up claims, or to test claims earlier made from the armchair, for example, on the perceived permissibility of diverting trolleys or on the nature of free will. This growing field of experimental philosophy has diversified the intellectual field in philosophy, but may also be vulnerable to issues of replicability that philosophers did not face before. -/- Third, the recent evidence of apparently widespread non-replicability in the social sciences (and other fields) has forced philosophers of science to grapple with long standing questions from their field from a new perspective. To what extent does replicability matter for theory construction? How do the notions of replicability and scientific progress interact? How can normative insights from philosophy of science be used in order to improve scientific practice? -/- It is with these three developments in mind—the increasing importance of empirically-informed philosophy, of experimental philosophy, and of philosophy of science around replicability—that this special issue has been conceived.

We contend that it is possible to argue reasonably for and against arguments from classifications and definitions, provided they are seen as defeasible (subject to exceptions and critical questioning). Arguments from classification of the most common sorts are shown to be based on defeasible reasoning of various kinds represented by patterns of logical reasoning called defeasible argumentation schemes. We show how such schemes can be identified with heuristics, or short-cut solutions to a problem. We examine a variety of arguments of (...) this sort, including argument from abductive classification, argument from causal classification, argument from analogy-based classification and arguments from classification based on generalizations.
