Based on 10 months of mixed ethnographic and archival research, this study is concerned with ways in which contemporary agro-environmental subjectivities and practices in a southwestern Oklahoma farming community are rooted in the massive state-level interventions of the New Deal era and their successors. We are likewise concerned with how those interventions have become interdigitated with moral discourses and community ethics, as simultaneous expressions of both farmers’ identities and the systems of power in which they practice farming. Through historic and (...) ethnographic evidence, we demonstrate the ways in which the localization of American agricultural conservation and the attendant, edificatory role of resource bureaucracies have shaped contemporary practices and ideologies of natural resource stewardship among conventional farmers and ranchers.

What were Shakespeare's final thoughts on history, tragedy, and comedy? Shakespeare's Last Plays focuses much needed scholarly attention on Shakespeare's "Late Romances." The work--a collection of newly commissioned essays by leading scholars of classical political philosophy and literature--offers careful textual analysis of Pericles, Prince of Tyre, Cymbeline, The Winter's Tale, The Tempest, All is True, and The Two Noble Kinsmen. The essays reveal how Shakespeare's thought in these final works compliments, challenges, fulfills, or transforms previously held conceptions of the playwright (...) and his political-philosophical views.

Sur le versant Sud d'une colline appelée Sténokorifi, non loin de Drama, de nombreux filons de marbre dolomitique, gris clair et de petite granulométrie, affleurent sur une étendue d'environ 19 000 m2 entre une végétation dense. Excepté le front de taille vertical d'une exploitation marbrière des années 1950 qui a fait des essais d'extraction en profondeur à l'aide du marteau-piqueur, il n'y a que des fronts de taille obliques (selon la pente) et les extractions sont superficielles. Dès lors que les (...) filons présentent une masse homogène et compacte, des traces d'extraction sont visibles ; certaines d'entre elles (canaux, emboîtures, entailles pour coins, négatifs de blocs extraits) sont conformes à celles des techniques d'extraction de l'époque romaine, alors que d'autres «enfonçures » sont les témoins de la technique d'extraction à l'époque proto-byzantine. Deux fours à chaux ont été identifiés, l'un d'époque byzantine et l'autre contemporain de l'exploitation moderne, d'où la rareté des blocs abandonnés. (shrink)

Stimuli such as surprised faces are ambiguous in that they are associated with both positive and negative outcomes. Interestingly, people differ reliably in whether they evaluate these and other ambiguous stimuli as positive or negative, and we have argued that a positive evaluation relies in part on a biasing of the appraisal processes via reappraisal. To further test this idea, we conducted two studies to evaluate whether increasing the cognitive accessibility of reappraisal through a brief emotion regulation task would lead (...) to an increase in positive evaluations of ambiguity. Supporting this prediction, we demonstrated that cuing reappraisal, but not in three other forms of emotion regulation (Study 1a-d; n = 120), increased positive evaluations of ambiguous faces. In a sign of robustness, we also found that the effect of reappraisal generalised from ambiguous faces to ambiguous scenes (Study 2; n = 34). Collectively, these findings suggest that reappraisal may play a key role in determining responses to ambiguous stimuli. We discuss these findings in the context of affective flexibility, and suggest that valence bias (i.e. the tendency to evaluate ambiguity more positively or negatively) represents a novel approach to measuring implicit emotion regulation.

In this paper, we introduce and defend the recurrent model for understanding bodily spatial phenomenology. While Longo, Azañón and Haggard (2010) propose a bottom-up model, Bermúdez (2017) emphasizes the top-down aspect of the information processing loop. We argue that both are only half of the story. Section 1 intro- duces what the issues are. Section 2 starts by explaining why the top- down, descending direction is necessary with the illustration from the ‘body-based tactile rescaling’ paradigm (de Vignemont, Ehrsson and Haggard, (...) 2005). It then argues that the bottom-up, ascending direction is also necessary, and substantiates this view with recent research on skin space and tactile field (Haggard et al., 2017). Section 3 discusses the model’s application to body ownership and bodily self-representation. Implications also extend to topics such as sense modality individuation (Macpherson, 2011), the constancy- based view of perception (Burge, 2010), and the perception/cognition divide (Firestone and Scholl, 2016).

Background Escalating levels of obesity place enormous and growing demands on Health care provision in the (U.K.) United Kingdom. Resources are limited with increasing and competing demands upon them. Ethical considerations underpin clinical decision making generally, but there is limited evidence regarding the relationship between these variables particularly in terms of treating individuals with obesity. Research aim To investigate the views of National Health Service (NHS) clinicians on navigating the ethical challenges and decision making associated with obesity management in adults (...) with chronic illness. Research design A cross-sectional, multi-site survey distributed electronically. Participants A consensus sample of nurses, doctors, dietitians and final year students in two NHS Trusts and two Universities. Ethical considerations Ethical and governance approvals obtained from a National Ethics Committee (11NIR035), two universities and two teaching hospitals. Results Of the total ( n = 395) participants, the majority were nurses (48%), female (79%) and qualified clinicians (59%). Participants strongly considered the individual to have primary responsibility for a healthy weight and an obligation to attempt to maintain that healthy weight if they wish to access NHS care. Yet two thirds would not withhold treatment for patients with obesity. Discussion While clinicians were clear about patient responsibility and obligations, the majority prioritised their duty of care and would not invoke a utilitarian approach to decision making. This may reflect awareness of obesity as a multi-faceted entity, with responsibility for support and management shared amongst society in general. Conclusions The attitudes of this sample of clinicians complemented the concept of the health service as being built on a principle of community, with each treated according to their need. However limited resources challenge the concept of needs-based decisions consequently societal engagement is necessary to agree a pragmatic way forward. (shrink)

À travers l’ouvrage Le Successeur de pierre par Jean-Michel Truong et à la lumière des théories de Félix Guattari, de Mark B. N. Hansen et de Brian Rotman relatives aux multiples virtualités de l’être humain, cet article étudiera la narration romanesque de l’imbrication des nouvelles technologies de l’information et de la communication dans les processus de matérialisation et d’agentivité du posthumain. Dans son roman, Truong nous invite en effet à repenser la contextualité du corps et de l’identité humaine en substituant (...) un point de vue anthropocentrique et dualiste à une ontologie de l’émergence. This paper investigates Jean-Michel Truong’s book Le Successeur de pierre with Felix Guattari’s, Mark B. N. Hansen’s and Brian Rotman’s theories related to the multiple potentialities of human beings. It focuses more precisely on the fictional narrative of the new information and communication imbrication of technologies into the processes of posthuman’s materialisation and agency. In his novel, Truong indeed invites us to think over the contextuality of the body and the human identity by substituting an anthropocentric and dualistic point of view with an ontology of emergence.

This essay is an inquiry into John McDowell’s thinking on ‘subjectivity.’ The project consists in two parts. On the one hand, I will discuss how McDowell understands and responds to the various issues he is tackling; on the other, I will approach relevant issues concerning subjectivity by considering different aspects of it: a subject as a perceiver, knower, thinker, speaker, agent, person and (self-) conscious being in the world. The inquiry begins by identifying and resolving a tension generated by the (...) very idea of ‘rational animal’: human beings are at the same time natural and rational. Later the inquiry proceeds by considering how McDowell’s notion of ‘second nature’ enables us to be human subjects with many faces. By going through the diagnoses and responses of McDowell, two central problems in modern and contemporary philosophy – the narrow conception of nature and the Cartesian inner space model – are identified and repelled. In Episode N I first urge that we should leave room for a certain notion of ‘world.’ I further argue that mentality has many aspects, and to understand those aspects is to understand the many faces of human subject. In Episode Ⅰ the Aristotelian notion of ‘second nature’ is discussed in order to resolve the tension in the very idea of ‘rational animal.’ Later I reply to some worries about this maneuver, including the objection from Crispin Wright. Hans-Georg Gadamer’s distinction between world and environment is introduced and related to McDowell’s thinking. Episode Ⅱ discusses perception and knowledge; McDowell’s main target – the Cartesian inner space – is introduced and criticized. Barry Stroud’s and Simon Blackburn’s positions are evaluated. Later I connect the main theme of Mind and World to the present context; in particular, I discuss McDowell’s invocation of Donald Davidson and Immanuel Kant. And then I discuss a common accusation of idealism, and Robert Brandom’s accusation of ‘residual individualism.’ Episode Ⅲ concentrates on Saul Kripke’s Wittgenstein, arguing that the master thesis behind the rule-following paradox is a version of the inner space model, and that Kripke’s Wittgenstein is not Wittgenstein. Martin Kusch’s objections are answered; Michael Dummett’s demand of reductionism is rebutted. After this, I turn to Davidson’s ‘no language’ claim, and discuss to what extent McDowell agrees with him. In Episode Ⅳ I evaluate objections from Hubert Dreyfus concerning action and agency. I discuss how Dreyfus and Maurice Merleau-Ponty commit ‘the Myth of the Disembodied Intellect’ identified by McDowell. I answer Michael Ayer’s charge of intellectualism in passing. Later I bring in McDowell’s objections to Derek Parfit on personhood and to Davidson on the mind-body relation. In Episode Ⅴ I focus on consciousness and self-consciousness. McDowell applies his argument against Parfit to Kant, but Maximilian de Gaynesford dissents. I reply to his objections on McDowell’s behalf. I further connect this to McDowell’s attacks on the dualism of scheme and content. This leads to my McDowellian rejection to the existence of qualia, and further brings me to the debate between intentionalism and disjunctivism in the context of the argument from illusion. I argue against Tim Crane’s ways of conceiving issues about intentionalism and the argument from illusion. Varieties of disjunctivism are also discussed. In my Epilogue, I express my worry about McDowell’s notion of ‘self-determining subjectivity.’ According to McDowell, human freedom consists in causations in the space of reason, but as Richard Gaskin points out, a satisfying story of it is yet to be provided. I close this essay with some rough ideas about how to fill in the details of the McDowellian picture. (shrink)

Résumé La recherche économique contemporaine a perdu (de) sa puissance explicative. Bien que cela transparaisse déjà depuis un bon moment, ce n’est que depuis la récente crise économique que cet état de fait est reconnu de manière plus générale. Cependant, plusieurs initiatives ont étés lancées dans l’espoir d’améliorer la situation. Une initiative phare fut celle qu’a lancée George Soros, à partir du constat suivant: si la réflexivité est une composante majeure de la réalité sociale, les contributions dominantes actuelles en économie (...) n’intègrent pas cette dimension. Le propos de mon article est de montrer que si Soros nous donne un éclairage pertinent, il ne pousse pas assez loin son raisonnement. L’essence de son message risque de se perdre en conséquence de certains propos qu’il faut mettre en doute et qui ne sont peut-être pas nécessaires à son argumentation centrale – des propos que l’on peut retrouver ailleurs dans la quête d’alternatives, et qui méritent à ce titre une attention particulière.

A major recurrent feature of the intellectual landscape in cognitive science is the appearance of a collection of essays by Noam Chomsky. These collections serve both to inform the wider cognitive science community about the latest developments in the approach to the study of language that Chomsky has advocated for almost fifty years now,1 and to provide trenchant criticisms of what he takes to be mistaken philosophical objections to this approach. This new collection contains seven essays, the earliest of which (...) were first published about ten years ago. So the linguistic work that is summarised is within the principles and parameters approach and some of the essays (particularly the first and last) provide an outline of the main ideas of the emerging minimalist programme.2 But this is not primarily a book about the details of recent linguistic theory. Rather, in these essays Chomsky offers a wealth of critical commentary on some of the most influential arguments in the philosophy of mind and language that have appeared over the past two decades or so. Indeed, Chomsky discusses a vast range of philosophical topics and reaches some radical conclusions – that many influential philosophical discussions on language and mind are utterly misconceived and that, for example, the traditional mind-body problem cannot even be coherently stated.

Dans cet article, on analyse des données nouvelles concernant l'histoire des nombres amiables. Les textes hébreux qui sont cités permettent d'éclairer la diffusion, dans l'Europe médiévale, des résultats établis par Tābit ibn Qurra au IXesiècle: en effet, le théorème sur les nombres amiables auquel est attaché son nom apparaît aussi bien dans une traduction effectuée à Saragosse, en 1395, d'un commentaire arithmétique d'Abū al-Ṣalt al-Andalusī (ca. 1068–1134), que dans une composition originale attribuée au savant juif provençal Qalonymos ben Qalonymos d'Arles (...)

Given the nature of the discipline, it might be assumed that clinical psychology is an ethical profession, within which effective ethical decision-making is integral. How then, does this ethical decision-making occur? This paper describes a systematic review of empirical research addressing this question. The paucity of evidence related to this question meant that the scope was broadened to include other professions who deliver talking therapies. This review could support reflective practice about what may be taken into account when making ethical (...) decisions and highlight areas for future research. Using academic search databases, original research articles were identified from peer-reviewed journals. Articles using qualitative ( n = 3), quantitative ( n = 8) and mixed methods ( n = 2) were included. Two theoretical models of aspects of ethical decision-making were identified. Areas of agreement and debate are described in relation to factors linked to the professional, which impacted ethical decision-making. Factors relating to ethical dilemmas, which impacted ethical decision-making, are discussed. Articles were appraised by two independent raters, using quality assessment criteria, which suggested areas of methodological strengths and weaknesses. Comparison and synthesis of results revealed that the research did not generally pertain to current clinical practice of talking therapies or the particular socio-political context of the UK healthcare system. There was limited research into ethical decision-making amongst specific professions, including clinical psychology. Generalisability was limited due to methodological issues, indicating avenues for future research. (shrink)

Working parents in are struggling to balance the demands of their occupation with those of childcare and homeschooling during the COVID-19 pandemic. Moreover, studies show that women are shouldering more of the burden and reporting greater levels of psychological distress, anxiety, and depression relative to men. However, research has yet to show that increases in psychological symptoms are linked to changes in stress during the pandemic. Herein, we conduct a small-N study to explore the associations between stress and psychological symptoms (...) during the pandemic among mothers using structural equation modeling, namely latent change score models. Thirty-three mothers completed questionnaires reporting current anxious and depressive symptoms, as well as stressful life experiences prior to-versus during the pandemic. Women endorsed significantly more stressful events during the pandemic, relative to the pre-pandemic period. Additionally, 58% of mothers scored as moderate-to-high risk for developing a stress-related physical illness in the near future because of their pandemic-level stress. Depressive symptoms were associated with the degree of change in life stress, whereas anxiety symptoms were more related to pre-pandemic levels of stress. The present study preliminarily sheds light on the nuanced antecedents to mothers’ experiences of anxious and depressive symptoms during the COVID-19 pandemic. Although further work is needed in larger, more diverse samples of mothers, this study highlights the potential need for appropriate policies, and prevention and intervention programs to ameliorate the effects of pandemics on mothers’ mental health.

To combat the OneHealth threat of antimicrobial resistance (AMR), the use of antibiotics in agriculture is subject to significant governance-led initiatives to change food system behaviours, including promoting more responsible use of antibiotics on farms through market-level interventions. To combat knowledge gaps about how consumers perceive risks associated with antibiotic use and AMR in farming, the current study carried out an in-depth qualitative focus group study incorporating a risk information exposure exercise with food consumers on the island of Ireland (_n_ (...) = 36). Using a theoretical lens of social representation theory, a thematic analysis of the collected data identified how participants made sense of, often new, information on agricultural antibiotic use and AMR. Participants displayed high awareness and concern for AMR but low understanding and misconceptions around AMR transmission from the agri-food sector. Social representations about antibiotics and food and farming systems shaped preferences for a movement away from antibiotics in farming, and in particular, prophylactic use. However, participants acknowledged the role of antibiotics to protect animal health and the integrity of the food supply chain. They debated the lack of a simple fix to antibiotics in the agri-food system and revealed preferences for preventive actions at farm level and supporting actions at market level. The study highlights the need to first tackle low levels of public understanding through effective risk communication including strategies such as targeted message framing and proactive, cross-sector OneHealth awareness campaigns, followed by the introduction of a trusted antibiotic use food labelling system.

Lower levels of news use are generally understood to be associated with less political engagement among citizens. But while some people simply have a low preference for news, others avoid the news intentionally. So far little is known about the relationship between active news avoidance and civic engagement in society, a void this study has set out to fill. Based on a four-wave general population panel survey in the Netherlands, conducted between April and July 2020 (N = 1,084) during a (...) crisis situation, this research-in-brief investigates the development of news avoidance and pro-social civic engagement over time. Results suggest that higher news topic avoidance results in higher levels of civic engagement. The study discusses different explanations for why less news can mean more engagement. (shrink)

Research on nursing ideology and the ethics of child and adolescent psychiatric nursing care is limited. The aim of this study was to describe and explore the ideological approaches guiding psychiatric nursing in child and adolescent psychiatric inpatient wards in Finland, and discuss the ethical, theoretical and practical concerns related to nursing ideologies. Data were collected by means of a national questionnaire survey, which included one open-ended question seeking managers' opinions on the nursing ideology used in their area of practice. (...) Questionnaires were sent to all child and adolescent psychiatric inpatient wards (n = 69) in Finland; 61 ward mangers responded. Data were analysed by qualitative and quantitative content analysis. Six categories - family centred care, individual care, milieu centred care, integrated care, educational care and psychodynamic care - were formed to specify ideological approaches used in inpatient nursing. The majority of the wards were guided by two or more approaches. Nursing models, theories and codes of ethics were almost totally ignored in the ward managers' ideological descriptions. (shrink)

Populist attributions of blame have important effects on citizens’ attitudes, cognitions, emotions, and behaviors. Extending previous studies that have mostly looked at populist messages blaming political elites, we use an online survey experiment (N = 805) to investigate the effects of blaming different elitist actors in populist and non-populist ways: (1) political elites, (2) corporate elites, (3) scientific elites, and (4) a combination of these elites. We compare mere causal responsibility attribution to populist blame attributions that highlight a central opposition (...) between “pure ordinary people” and “corrupt elites” to tease out the specific effect of populist rhetoric. Results suggest that populist messages blaming all elites have stronger effects than isolated cues. Furthermore, populist blame attribution leads to more negative perceptions of the elites than non-populist blame attribution. The finding that populist frames can – under some conditions – activate negative perceptions toward different elites is alarming in times of declining trust in societal institutions, and calls for a more encompassing understanding of populists’ scapegoats.

Abortion and euthanasia are still one of the greatest bioethical challenges. Previous studies have shown that there are differences in attitudes towards these issues depending on socio-demographic characteristics and socio-cultural environment (country of residence). As part of the scientific research project EuroBioMed, we compared the attitudes of students from three Mediterranean countries towards abortion and euthanasia and examined them from the perspective of Mediterranean bioethics. A pen-to-paper survey was conducted on a convenient sample of students (N = 1097) from five (...) universities and four fields of study (Medicine, Law, Theology and Philosophy) in Croatia, Greece and Italy to investigate their attitudes towards abortion and euthanasia. Three hypotheses were tested using t-test and ANOVA for differences in attitudes according to country, field of study, year of study, gender, religiosity, political orientation, financial status, and size of place of residence. While attitudes towards abortion were not statistically significantly different between students from different countries, the analysis showed that students from Italy had more liberal attitudes towards euthanasia. Theology students had more conservative attitudes towards both abortion and euthanasia, while there were no differences between the other groups. Women, final year students, non-religious and politically left-oriented students had more liberal attitudes. The results provided an insight into students’ attitudes towards abortion and euthanasia. Knowledge of the attitudes of these future experts can be valuable for the discussion of these issues. These results also provided a basis for a better understanding of the construct of Mediterranean bioethics. (shrink)

Misinformation perceptions related to global crises such as COVID-19 can have negative ramifications for democracy. Beliefs related to the prevalence of falsehoods may increase news avoidance or even vaccine hesitancy – a problematic context for successful interventions and policymaking. To explore how misinformation beliefs developed over a six-month pandemic period and how they corresponded to (digital) media preferences and selective exposure to the news, we rely on a five-wave panel survey conducted in the Netherlands (N =1,742). Our main findings show (...) that misinformation perceptions got more pronounced as the pandemic evolved. Social media use related to more pronounced misinformation beliefs within waves, whereas mainstream news use corresponded to less pronounced misinformation beliefs. An important implication for journalists and policymakers is to lower the over-time accumulation of misinformation perceptions, for example, by increasing transparency and acknowledging “honest mistakes.”.

This timely, well‐written book illuminates an aspect of Brazilian science that has long been neglected, for two major reasons. The first is that it is only in the past two decades that the scientific past of Latin America, including Brazil, seemed to merit systematic academic investigation, and only with this change have scholars discovered, or rediscovered, several important, but forgotten, developments, such as the one Julyan Peard analyzes in this study. The second reason is that, although there is a substantial (...) literature on late nineteenth‐ to early twentieth‐century colonial science and medicine—which is considered almost synonymous with tropical medicine—none of it treats Brazil or any of the other Latin American countries because, even though they fall within the tropical zone, they were formally independent nations from the early 1800s onward.Peard rejects this adherence to the old criterion for defining “tropical.” Drawing on a respectable collection of both primary and secondary sources, she tells the story of the Escola Tropicalista Bahiana , which was founded before the revolution in bacteriological knowledge and the great European colonial expansion. The idea for the school originated, Peard says, with “a group of nineteenth‐century doctors in Brazil who, in attempting to adapt Western medicine to more fully engage with the problems of their tropical country, sought novel answers to the age‐old question of whether diseases of warm climates were distinct from those of temperate Europe. In their search, they used the tools of Western medicine to confront European ideas about the fatalism of the tropics and its people, and to argue in favor of Brazilian expertise.”The text is organized into five chapters, whose titles clearly describe both the structure of the narrative and Peard's main points, as well as part of her conclusions: “The Escola Tropicalista Bahiana: A Creative Response in Adversity”; “The Politics of Disease”; “Race, Climate, Medicine: Framing Tropical Disorders”; “Physicians and Women in Bahia”; and “Moving into Mainstream.” In her introduction Peard presents a useful discussion of the earlier literature on her topic, pointing out her contribution to several relevant fields. Throughout, the text is structured to highlight the tension between the Tropicalistas and European science: “although they [the Tropicalistas] resisted aspects of European cultural authority that harped on Brazilian, and Latin American, inferiority, they wanted to gain the mantle of legitimacy that they believed only European science, as the leader in universal science, could bestow on them.” Peard shows, chapter by chapter, the Tropicalistas' sometimes conscious, sometimes intuitive strategies to build up an innovative scientific field, a project that entailed issues of national identity and the regional response to the centralized imperial authority of Rio de Janeiro. Almost half the volume is devoted to supplementary material: three useful appendixes, notes to all the chapters, a list of primary sources, the bibliography, and a well‐elaborated index—all of which testify to the quality of both Peard's research and her book as a whole.It is important to stress here that Peard relies on what one could call the “new” Brazilian history and sociology of science, particularly in the fields of medicine and public health. Despite its vigorous growth, both quantitatively and qualitatively, this historiography still remains more or less confined to Latin America, its wider dissemination impeded by language barriers. In using and commenting on the bibliography of this new historiography, Peard respects the local intellectual production while helping to enrich the traditional set of references. Nevertheless, and although I warmly recommend the book, I regret that she did not fully incorporate the conclusions reached by this recent historiography, preferring instead to present essentially the same picture drawn in previous works, a picture based on the view that “in the few instances of research work being carried out in Brazil before 1900 such work was sporadic, isolated … or incapable of being self‐sustaining.”.

We give an introductory tutorial to assumption-based argumentation (referred to as ABA) – a form of argumentation where arguments and attacks are notions derived from primitive notions of rules in a deductive system, assumptions and contraries thereof. ABA is equipped with different semantics for determining ‘winning’ sets of assumptions and – interchangeably and equivalently – ‘winning’ sets of arguments. It is also equipped with a catalogue of computational techniques to determine whether given conclusions can be supported by a ‘winning’ set (...) of arguments. These are in the form of disputes between (fictional) proponent and opponent players, provably correct w.r.t. the semantics. Albeit simple, ABA is powerful in that it can be used to represent and reason with a number of problems in AI and beyond: non-monotonic reasoning, preferences, decisions. While doing so, it encompasses the expressive and computational needs of these problems while affording the transparency and explanatory power of argumentation. (shrink)

There are two traditional ways to read Kant's claim that every event necessarily has a cause: the weaker every-event some-cause and the stronger same-cause same-effect causal principles. The focus of the debate about whether and where he subscribes to the SCP has been in the Analogies in the Critique of Pure Reason and in the Metaphysical Foundations of Natural Science. By analysing the arguments and conclusions of both the Analogies and the Postulates as well as the two Latin principles non (...) datur casus and non datur fatum that summarise their results, I will argue for the novel thesis that the SCP is actually demonstrated in the Postulates of the First Critique.

Dung’s abstract argumentation frameworks have had a very significant role in the rise in interest in argumentation throughout this century. In this paper we will explore the impact of this seminal idea on a specific application domain, AI and Law. Argumentation is central to legal reasoning and there had been a considerable amount of work on it in AI and Law before Dung’s paper. It had, however, been rather fragmented. We argue that the abstract argumentation frameworks had a unifying effect (...) by offering a means of relating previously diverse work. We also discuss how the particular demands of legal systems have led to developments building on the basic notions of abstract argumentation. (shrink)

dialectical frameworks (ADFs) are generalizations of Dung argumentation frameworks where arbitrary relationships among arguments can be formalized. This additional expressibility comes with the price of higher computational complexity, thus an understanding of potentially easier subclasses is essential. Compared to Dung argumentation frameworks, where several subclasses such as acyclic and symmetric frameworks are well understood, there has been no in-depth analysis for ADFs in such direction yet (with the notable exception of bipolar ADFs). In this work, we introduce certain subclasses of (...) ADFs and investigate their properties. In particular, we show that for acyclic ADFs, the different semantics coincide. On the other hand, we show that the concept of symmetry is less powerful for ADFs and further restrictions are required to achieve results that are similar to the known ones for Dung’s frameworks. A particular such subclass (support-free symmetric ADFs) turns out to be closely related to argumentation frameworks with collective attacks (SETAFs); we investigate this relation in detail and obtain as a by-product that even for SETAFs symmetry is less powerful than for AFs. We also discuss the role of odd-length cycles in the subclasses we have introduced. Finally, we analyse the expressiveness of the ADF subclasses we introduce in terms of signatures. (shrink)

Building on work by Popper, Schweber, Nozick, Sober, and others in a still-growing literature, I explore here the conceptual kinship between Adam Smith''s ''invisible hand'' and Darwinian natural selection. I review the historical ties, and examine Ullman -Margalit''s ''constraints'' on invisible-hand accounts, which I later re-apply to natural selection, bringing home the close relationship. These theories share a ''parent'' principle, itself neither biological no politico-economic, that collective order and well-being can emerge parsimoniously from the dispersed action of individuals. The invisible (...) hand operates on ''memes'' the way natural selection operates on genes. Like Darwin''s concept, it brings together traditional opposites, ''nature'' and ''selection,'' forming a saltation-mitigating transition between biological instinct and full-blown conscious design. Herschel''s criterion of confirmation, which Darwin long strove to satisfy, is itself an invisible hand-like meme – a ''Midas effect'' revealing and rewarding the fittest theories, Darwin''s and Smith''s emphatically among them.

La fraternidad es el pariente pobre de la tríada democrático-republicana moderna. No sólo políticamente. También filosóficamente: mientras que los conceptos de «igualdad" y "libertad" han sido concienzudamente explorados, "fraternidad», sigue pareciendo una noción amorfa. Este artículo presenta una reivindicación política, a la altura de finales del siglo XX, de la fraternidad, e intenta dibujar filosóficamente, tras un preámbulo histórico, un concepto algo preciso y proteico de ella.

In the presentation I will analyse Kant’s conception of modalities and consider its relevance to his critical metaphysics. With his Tables of Judgements and of Categories Kant makes an important division between two kinds of modality, of which the former is only logical and the latter transcendental, i.e., objective. Only judgements that are necessary in both ways are properly metaphysical. This distinction is important for Kant’s distinction between Transcendental Analytic and Transcendental Dialectic, i.e., between acceptable and unacceptable metaphysics. I submit (...) that not only is Kant’s theory of modality useful for properly understanding his arguments in the Dialectic, but that only by distinguishing between the two types of modality can one can make sense of his theory that the ideas of reason are simultaneously inevitable and erroneous. This modal analysis thus offers a new and important point of view to Kant’s metaphysics and its critique. (shrink)

The notion of similarity has been studied in many areas of Computer Science; in a general sense, this concept is defined to provide a measure of the semantic equivalence between two pieces of knowledge, expressing how “close” their meaning can be regarded. In this work, we study similarity as a tool useful to improve the representation of arguments, the interpretation of the relations between arguments, and the semantic evaluation associated with the arguments in the argumentative process. In this direction, we (...) present a novel mechanism to determine the similarity between two arguments based on descriptors representing particular aspects associated with these arguments. This mechanism involves a comparison process influenced by the context in which the process develops, where this context provides the relevant aspects that need to be analyzed in the application domain. Then, we use this similarity measure as a quantity to compute the result of attacks and supports in the argumentation process. These valuations, applied to a Bipolar Argumentation Frameworks, allowed us to refine the argument relations, providing the tools to establish a family of new argumentation semantics that considers the similarity between arguments as a crucial part for the argumentation process.

In The Value Gap, Toni Rønnow-Rasmussen addresses the distinction between what is finally good and what is finally good-for, two value notions that are central to ethics and practical deliberation. The first part of the book argues against views that claim that one of these notions is either faulty, or at best conceptually dependent on the other notion. Whereas these two views disagree on whether it is good or good-for that is the flawed or dependent concept, it is argued, (...) as against both approaches, that goodness and goodness-for are independent value notions that cannot be fully understood in terms of one another. The second part provides an analysis of good and good-for in terms of a fitting-attitude analysis. By elaborating a more nuanced understanding of the key elements of this analysis—reasons and pro-attitudes—Rønnow-Rasmussen challenges the widespread idea that there are no genuine practical and moral dilemmas. The result is that the gap between favouring for a reason what is good and favouring for a reason what is good for someone appears insurmountable. (shrink)

In the course of his philosophy, in various contexts, Kant comes to reject three theses about existence: (i) that the thoroughgoing determination of a thing implies its existence, (ii) that existence is a real predicate or determination of a thing, and (iii) that existence is the complement of inner possibility or essence. Kant’s target here is Baumgarten, who advocates these theses as the criterion, classification, and definition of existence. In this article I seek to clarify Kant’s elusive theory of existence (...) through its opposition to Baumgarten. I will show that Kant’s refutation of (i)–(iii) does not stand alone but is grounded on his own definition of existence as (absolute) positing. Thus contrary to common practice, Kant’s negative claims about what existence is not cannot be understood in isolation but must be taken as jointly dependent on Kant’s positive claim of what existence is. I will show that the theses (i)–(iii) fail because they presuppose that existence contributes to the intension or content of a concept, whereas according to Kant existence in fact posits a (non-empty) extension to the concept.
