We address the problems of localization, mapping, and guidance for robots with limited computational resources by combining vision with the metrical information given by the robot odometry. We propose in this article a novel light and robust topometric simultaneous localization and mapping framework using appearance-based visual loop-closure detection enhanced with the odometry. The main advantage of this combination is that the odometry makes the loop-closure detection more accurate and reactive, while the loop-closure detection enables the long-term use of odometry for (...) guidance by correcting the drift. The guidance approach is based on qualitative localization using vision and odometry, and is robust to visual sensor occlusions or changes in the scene. The resulting framework is incremental, real-time, and based on cheap sensors provided on many robots. This approach is, moreover, particularly well suited for low-power robots as it is not dependent on the image processing frequency and latency, and thus it can be applied using remote processing. The algorithm has been validated on a Pioneer P3DX mobile robot in indoor environments, and its robustness is demonstrated experimentally for a large range of odometry noise levels. (shrink)

La question de Dieu dans la pensée de Husserl fut très tôt un objet d'attention pour la recherche phénoménologique, mais la diversité des textes est telle qu'il était nécessaire d'établir le dossier historique relatif à cette question. Bien évidemment, la mise en lumière de l'unité et de la continuité des analyses de Husserl sur Dieu est animée par une interrogation proprement spéculative : quelle place pour Dieu dans une philosophie descriptive qui se veut méthodologiquement athée? A partir du "je" transcendantal, (...) quel est l'accès possible à la pure phénoménalité de Dieu? Si Husserl décrit la transcendance de Dieu comme celle d'une Idée théorique, éthique et téléologique, il ne s'agit pas pour lui de s'en tenir aux reconstructions abstraites de la métaphysique, niais de revenir à l'expérience originaire de Dieu. La réduction phénoménologique ne demande pas de cesser de croire, mais elle rend possible une purification éthique de l'expérience religieuse qui permet d'élucider son sens. En cela, tout le projet contemporain d'un concept non ontologique de Dieu est redevable à Husserl d'avoir fait le premier pas décisif en affranchissant de tout en soi " et en montrant que la transcendance de Dieu ne peut être séparée de la vie intentionnelle dans laquelle elle s'annonce. Husserl ne confond pas pour autant philosophie et théologie, et la compréhension de Dieu comme évidence d'une Idée pratique infinie laisse ouverte la possibilité de la Révélation sans vouloir parler pour elle.

Suszko’s problem is the problem of finding the minimal number of truth values needed to semantically characterize a syntactic consequence relation. Suszko proved that every Tarskian consequence relation can be characterized using only two truth values. Malinowski showed that this number can equal three if some of Tarski’s structural constraints are relaxed. By so doing, Malinowski introduced a case of so-called mixed consequence, allowing the notion of a designated value to vary between the premises and the conclusions of an argument. (...) In this article we give a more systematic perspective on Suszko’s problem and on mixed consequence. First, we prove general representation theorems relating structural properties of a consequence relation to their semantic interpretation, uncovering the semantic counterpart of substitution-invariance, and establishing that mixed consequence is fundamentally the semantic counterpart of the structural property of monotonicity. We use those theorems to derive maximum-rank results proved recently in a different setting by French and Ripley, as well as by Blasio, Marcos, and Wansing, for logics with various structural properties. We strengthen these results into exact rank results for nonpermeable logics. We discuss the underlying notion of rank, and the associated reduction proposed independently by Scott and Suszko. As emphasized by Suszko, that reduction fails to preserve compositionality in general, meaning that the resulting semantics is no longer truth-functional. We propose a modification of that notion of reduction, allowing us to prove that over compact logics with what we call regular connectives, rank results are maintained even if we request the preservation of truth-functionality and additional semantic properties.

The presupposition triggered by an expression E is generally satisfied by information that comes before rather than after E in the sentence or discourse. In Heim’s classic theory (1983), this left-right asymmetry is encoded in the lexical semantics of dynamic connectives and operators. But several recent analyses offer a more nuanced approach, in which presupposition satisfaction has two separate components: a general principle (which varies from theory to theory) specifies under what conditions a presupposition triggered by an expression E is (...) satisfied; and an ‘incremental’ component specifies that the principle must be checked on the basis of information that comes before E. Several researchers take this incremental component to be a processing bias, which can be overcome at some cost. If so, it should be possible, though costly, to satisfy presuppositions ‘symmetrically’, i.e. by taking into account linguistic material that comes both before and after the presupposition trigger. We test this claim with experimental means. Using inferential (and to some extent acceptability) tasks involving the anaphoric trigger aussi (‘too’) in French, we argue that symmetric readings are indeed possible (albeit degraded) in environments involving the connectives if, or, and unless.

La philosophie de la nature de l'Encyclopedie des sciences philosophiques fut, jusqu'a une date recente, presque ignoree par les etudes hegeliennes. Hegel s'y serait rendu coupable d'une pretention a concurrencer les sciences positives sur leur propre terrain et a rivaliser avec elles, en revelant a la fois son incomprehension de la scientificite la mieux etablie et la faible rationalite de son propre projet. Une lecture attentive permet de rectifier ces prejuges, en montrant non seulement que Hegel s'y trouve attentif et (...) respectueux du savoir positif de son temps, mais encore qu'il tente d'y definir les modalites d'une collaboration methodologiquement reglee entre philosophie et sciences. En quoi consiste le projet d'une science speculative? En quoi consiste chez Hegel la deduction speculative de la verite? En quoi consiste la comprehension hegelienne du statut et des formes du discours des sciences de la nature? Quelle attitude la speculation doit-elle adopter face aux controverses scientifiques? C'est a ces questions que s'efforce de repondre cet ouvrage. (shrink)

Over the last decade, businesses, policymakers, and researchers alike have advocated the need for value creation through inter-organizational collaboration. Researchers have widely argued that organizations that are engaged in collaborative processes create value. Because researchers have tended to focus on the identification of organizational motivations and on key success factors for collaboration, however, both the nature and processes of value creation in inter-organizational collaboration have yet to be examined. A recent theory by Austin and Seitanidi :726–758, 2012a; Nonprofit Volunt Sect (...) Q 41:929–968, 2012b) has proposed an analytical framework for analyzing value creation in inter-organizational collaboration, based on four types of value. The purpose of this current study is to empirically test this framework, and to provide key pointers for analyzing the nature of value, particularly in relation to learning. Our detailed empirical research is based on a 6-year retrospective case study of an inter-organizational partnership within an international development project for local economic development in Guatemala. The study’s contributions are twofold. First, it provides evidence of the critical path of the creation of diverse types of values in a collaborative process; second, it links the different types of value creation with the types of learning that occur in an inter-organizational process.

Emmanuel Levinas (1906–1996) has exerted a profound influence on 20th-century continental philosophy. This anthology, including Levinas's key philosophical texts over a period of more than forty years, provides an ideal introduction to his thought and offers insights into his most innovative ideas. Five of the ten essays presented here appear in English for the first time. An introduction by Adriaan Peperzak outlines Levinas's philosophical development and the basic themes of his writings. Each essay is accompanied by a brief introduction (...) and notes. This collection is an ideal text for students of philosophy concerned with understanding and assessing the work of this major philosopher. (shrink)

Since the beginning of the new millennium, initiatives known as roundtables have been developed to create voluntary sustainability standards for agricultural commodities. Intended to be private and voluntary in nature, these initiatives claim their legitimacy from their ability to ensure the participation of all categories of stakeholders in horizontal participatory and inclusive processes. This article characterizes the political and material instruments employed as the means of formulating agreement and taking a variety of voices into consideration in these arenas. Referring to (...) the specific case of the “Roundtable on Sustainable Palm Oil”, I undertake a detailed analysis of the tensions relating to different forms of participation, which create a gap between “local minority voices” and international stakeholders—either non-governmental organizations or industries. Local communities and small-scale farmers face difficulties when making their voices heard in the form of debate proposed. Firstly, some participants attempt to re-impose a vertical hierarchical relationship between small-scale farmers or affected communities and company managers/directors in order to deprive the former of their powers of representation and of being able to transform reality. Secondly, the liberalism of interest groups in the roundtable accords value to experts, global knowledge, strategy, and detachment, at the expense of other capabilities of rooted or attached people who come to defend their real lives with a desire to raise critical issues of injustice. In this context, I highlight the capacity of local NGOs to relieve some of those tensions and to help locally affected communities and small-scale farmers introduce public stages for debates, by accommodating other forms of participation apart from the liberal one. By being close to and by restoring their dignity through a specific work of solicitude and care, local NGOs prepare affected people for public speaking. (shrink)

La théorie critique de la société, telle qu'elle s'est développée dans le cadre de ce qu'on appelle parfois l'école de Francfort, se caractérise notamment par le fait qu'elle donne toute son importance aux dominations et aux conflits dans son analyse du monde contemporain. L'une de ses figures aujourd'hui centrales, Axel Honneth, est aussi l'auteur de la théorie de la reconnaissance sans doute la plus systématique et riche en perspectives théoriques et critiques. C'est de cette théorie qu'Emmanuel Renault part dans (...) cc livre, tout en lui apportant des inflexions justifiées d'une part par l'histoire de la théorie critique, d'autre part par l'analyse du temps présent. L'analyse de l'imbrication de la reconnaissance, de la domination et du conflit demande une approche spécifique : l'apport du pragmatisme américain et les débats sociologiques contemporains, en particulier Dewey et Bourdieu, complètent ici le modèle hégélien et les intuitions de Marx. Quelques exemples choisis parmi des objets souvent délaissés par les sciences sociales la conduite oppositionnelle d'un groupe de punks squatters, le langage protestataire de jeunes de banlieues populaires mettent à l'épreuve la capacité d'analyse de l'approche proposée par l'auteur, celle d'une philosophie sociale conçue comme une hybridation de la philosophie et des sciences sociales.

As Emmanuel Levinas states in the preface to Existence and Existents, "this study is a preparatory one. It examines . . . the problem of the Good, time, and the relationship with the other [person] as a movement toward the Good." First published in 1947, and written mostly during Levinas's imprisonment during World War II, this work provides the first sketch of his mature thought later developed fully in Totality and Infinity and Otherwise than Being, or Beyond Essence. This (...) new edition marks the first time this important work has been made available in an inexpensive paperback edition. Levinas's project in Existence and Existents is to move from anonymous existence to the emergence of subjectivity; to subjectivity's practice, theory and morality; to its encounter with the alterity of the other person. He is concerned here primarily with the time of the solitary subject; time is the inner structure of subjectivity, of the movement of existing. "Levinas's work," says Alphonso Lingis, "contains not only wholly new analyses of the forms of time of the present, the past, the future but also a new conception of the work of time." Beginning with Existence and Existents, then, it is possible to begin tracing the progressive "alterization" of time as it unfolds across the development of Levinas's entire philosophy. As a "preparatory" study, Existence and Existents introduces the major themes and concerns that occupied Levinas throughout his career. This is essential reading for understanding both Levinas's own philosophy and the developments in philosophical thought in the twentieth century. (shrink)

Albert Lautman,.philosophe, juif, fusillé par les Nazis pour faits de Résistance comme son ami et collègue Jean Cavaillès, a laissé inachevée une œuvre puissante et dont l'influence s'est fait sentir au-delà de son domaine. Lautman est une figure rare : un philosophe souverain, capable de mobiliser les grands noms de la tradition philosophique, de Platon à Heidegger, et suffisamment averti des mathématiques pour proposer une intelligence de leur développement acceptée des savants. Les membres du groupe Bourbaki ont reconnu en Lautman (...) un auteur exposant adéquatement les mathématiques auxquelles ils contribuaient ; Deleuze se réfère à lui de manière élogieuse ; Badiou, Petitot et Salanskis, notamment, lui font écho ou tentent de le prolonger. On examine ici cette œuvre dense, depuis Essai sur les notions de structure et d'existence en mathématiques et Essai sur l'unité des sciences mathématiques dans leur développement actuel aux textes posthumes, Symétrie et dissymétrie en mathématiques et en physique suivi du Problème du temps, après l'avoir située dans son contexte historique-scientifique. On espère ainsi montrer la profondeur et l'actualité d'une pensée singulière, celle d'un grand rationaliste qui était aussi un métaphysicien. (shrink)

For a long time, Gilbert Simondon’s work was known only as either a philosophy restricted to the problem of technology or as an inspirational source for Gilles Deleuze’s philosophy of difference. As Simondon’s thinking is now finally in the process of being recognized in its own right as one of the most original philosophies of the twentieth century, this also entails that some critical work needs to be done to disentangle it from an all too hasty identification with Deleuzian categories. (...) While both Simondon and Deleuze have made crucial contributions towards a theory of differential individuation that significantly diverges from other authors associated with French poststructuralism insofar as they insist on the dynamic and vital dimension of difference, they also differ on crucial points. Whereas Simondon sees the process of becoming as transductive amplification, Deleuze theorizes it as intensifying involution, leading to two notably distinct concepts of difference. (shrink)

A number of multi-stakeholder initiatives and commodity roundtables have been created since the 1990s to respond to the growing criticism of agriculture’s environmental and social impacts. Driven by private and global-scale actors, these initiatives are setting global standards for sustainable agricultural practices. They claim to follow the new standard-making virtues of inclusiveness and consensus and base their legitimacy on their claim of balanced representation of, and participation by, all categories of stakeholders. This principle of representing a wide range of interests (...) with a balance of power is at the heart of a new type of action that forms part of a broader political liberal model for building coalitions of interest groups. The intention of this symposium is to assess the nature of processes and outcomes of this model while paying particular attention to the forms of inclusion and exclusion they generate. In this introduction, we highlight the differences in theoretical approaches to analyzing MSIs and the manifestation of power through them. We distinguish between more traditional political–economy approaches and approaches concerned with ideational and normative power, such as convention theory. We discuss some of the main paradoxes of MSIs related to their willingness to be “inclusive” and at the same time their exclusionary or “closure” effects due in part to interactions with existing political economic contexts and embedded power inequalities, as well as more subtle manifestations of power linked to the favoring of some forms of knowledge and engagement over others.

Linguists often sharply distinguish the different modules that support linguistics competence, e.g., syntax, semantics, pragmatics. However, recent work has identified phenomena in syntax (polarity sensitivity) and pragmatics (implicatures), which seem to rely on semantic properties (monotonicity). We propose to investigate these phenomena and their connections as a window into the modularity of our linguistic knowledge. We conducted a series of experiments to gather the relevant syntactic, semantic and pragmatic judgments within a single paradigm. The comparison between these quantitative data leads (...) us to four main results, (i) Our results support a departure from one element of the classical Gricean approach, thus helping to clarify and settle an empirical debate. This first outcome also confirms the soundness of the methodology, as the results align with standard contemporary accounts of scalar implicature (SI), (ii) We confirm that the formal semantic notion of monotonicity underlies negative polarity item (NPI) syntactic acceptability, but (iii) our results indicate that the notion needed is perceived monotonicity. We see results (ii) and (iii) as the main contribution of this study: (ii) provides an empirical interpretation and confirmation of one of the insights of the model-theoretic approach to semantics, while (iii) calls for an incremental, cognitive implementation of the current generalizations, (iv) Finally, our results do not indicate that the relationship between NPI acceptability and monotonicity is mediated by pragmatic features related to Sis: this tells against elegant attempts to unify polarity sensitivity and Sis (pioneered by Krifka and Chierchia). These results illustrate a new methodology for integrating theoretically rigorous work in formal semantics with an experimentally-grounded cognitively-oriented view of linguistic competence.

BackgroundThe safety of sleeping pills has increased dramatically during the last 100 years, from barbiturates to bensodiazepines to modern day so-called Z-drugs.MethodsThe circumstances of prescribing sleeping pills in the early 20th century are illustrated by summarizing the main storyline of a novel by Swedish writer Vilhelm Moberg. This is followed by a thought experiment and a theoretical discussion.ResultsIn his 1937 novel Sömnlös (Swedish for sleepless) Vilhelm Moberg portrayed existential and relational distress in relation to insomnia. In a thought experiment, past (...) progresses in sleeping pills safety are projected into the future. Thereby, it is claimed that important issues in the area of philosophy of medicine come to the fore. This leads to a theoretical discussion about broader questions concerning the role of the physician, the goals of medicine (as described by Lennart Nordenfelt), the concept of pharmaceuticalisation (as described notably by sociologist of sleep Simon J. Williams and co-workers), and health enhancement (c.f. Carl Elliott and the alleged wish to be better than well).ConclusionInsomnia is a prism through which important philosophical and sociological questions related to the practice of medicine can be asked.

According to Wiredu, the Akan profess secular esteem rather than religious worship to supra-natural beings, who they perceive in an empirical sense. He backs this up by re-reading what he sees as the Akan general ontology in a way that denies them of the concepts of the supernatural, the transcendental, the mental, the spiritual, and an ontologically distinct mind. At the end of denying the three criteria of worship as well as all of these other concepts which might otherwise be (...) available to the Akan, one might struggle to find any evidence that the Akan even had a religion. I dispute this secular reading, and I more generally demonstrate that the characterizations of the Akan attitude to divinity as non-worshipping, non-supernatural, non-transcendent, and non-spiritual, are either conceptually flawed, factually incorrect, or both.

Shareholder activism has become a force for good in the extant corporate governance literature. In this article, we present a case study of Nigeria to show how shareholder activism, as a corporate governance mechanism, can constitute a space for unhealthy politics and turbulent politicking, which is a reflection of the country’s brand of politics. As a result, we point out some translational challenges, and suggest more caution, in the diffusion of corporate governance practices across different institutional environments. We contribute to (...) the literature on corporate governance in Africa, whilst creating an understanding of the political embeddedness of shareholder activism in different institutional contexts—i.e. a step closer to a political theorising of shareholder activism.

This book starts off from a philosophical premise: nobody can be in the world unless they are born into the world.

Images have always stirred ambivalent reactions. Yet whether eliciting fascinated gazes or iconoclastic repulsion from their beholders, they have hardly ever been seen as true sources of knowledge. They were long viewed as mere appearances, placeholders for the things themselves or deceptive illusions. Today, the traditional critique of the spectacle has given way to an unconditional embrace of the visual. However, we still lack a persuasive theoretical account of how images work. -/- Emmanuel Alloa retraces the history of Western (...) attitudes toward the visual to propose a major rethinking of images as irreplaceable agents of our everyday engagement with the world. He examines how ideas of images and their powers have been constructed in Western humanities, art theory, and philosophy, developing a novel genealogy of both visual studies and the concept of the medium. Alloa reconstructs the earliest Western media theory—Aristotle’s concept of the diaphanous milieu of vision—and the significance of its subsequent erasure in the history of science. Ultimately, he argues for a historically informed phenomenology of images and visual media that explains why images are not simply referential depictions, windows onto the world. Instead, images constantly reactivate the power of appearing. As media of visualization, they allow things to appear that could not be visible except in and through these very material devices.

Wiredu’s call for democracy by consensus is illustrated by his description of traditional African consensual rationality. This description contains the attribution of immanence to African consensual rationality. This paper objects to this doctrine of immanence. More importantly, the doctrine of immanence has led to the attribution of pure rationality to traditional African consensual practices. With reference to Aristotle’s three components of persuasion, I object to deliberation as purely rational and impervious to extraneous factors. I further argue that it is because (...) deliberation is not always perfectly rational that the process of consensus can suffer three forms of social conformity: conformity to dominant players, to numerical opinion majority, and to group-centrism. These forms of conformity mean that a consensus task order could lead to decisions of more inclusive value, but not necessarily decisions of more epistemic value. The concept of agonistic inquiry is employed to tackle what I see as the dangers of conformity and complacency in the project of inclusivity, and this is to strike a crucial balance between too-consensual and purely adversarial forms of deliberation.

A la fin du XVIIIe siècle, la philosophie, dans un débat autour de l'héritage de Kant, s'autodétermine comme système de la liberté, pour achever la révolution copernicienne, et accéder, dans le système du savoir, au concept, à la conscience de soi. La liberté s'affirme comme identité du penser et de l'être. Schelling est alors inspiré d'une part par Spinoza, et d'autre part par Kant et Fichte.

Les religions sont-elles condamnées à s'opposer et à être source de conflits en raison de la diversité et du caractère souvent contradictoire de leurs doctrines? Lorsqu'elles sont missionnaires et prétendent détenir la vérité sur Dieu, le monde et l'homme, le caractère systématique de leurs énoncés théologiques et juridiques qui excluent les autres systèmes ne redouble-t-il pas ces conflits? Comment dans ces conditions le dialogue interreligieux pourrait-il aller au-delà des rencontres et du dialogue de vie? Peut-on penser du point de vue (...) théologique une ouverture à l'autre qui assoie l'unité entre les religions, leur communion et leur réconciliation au niveau de la doctrine sans obliger chacune à renoncer aux énoncés de sa foi?0Pour envisager ces questions fondamentales qui concernent tous les acteurs impliqués dans le dialogue interreligieux ou la théologie du pluralisme religieux, plusieurs théologiens ont interrogé George Lindbeck afin d'évaluer si les principes qu'il avance pour repenser l'oecuménisme sont transposables au niveau de l'interreligieux. En effet, conscient de l'enjeu des différences doctrinales entre les Églises chrétiennes, Lindbeck a questionné la nature d'une doctrine et a proposé un modèle post-libéral privilégiant la praxis, l'articulation entre l'action et le langage, la réactivation et la réadaptation constante des identités. Ces recherches montrent qu'en dépit de bien des limites de son modèle, on trouve chez le théologien luthérien une approche originale et féconde pour répondre à bien des défis contemporains. (shrink)

This article examines the controversy that has arisen in the last decade about Michel Foucault’s supposed “fascination” with neoliberalism, especially around the contributions of Daniel Zamora and Michael C. Behrent. Their theses are contrasted with Foucauldian writings and reconsidered from a different approach to the historical, political and intellectual context of the French 1970s, which, in our opinion, shows a lack of complexity in the studies of those authors. Thus, this paper tries to establish that the limitations of Michel Foucault’s (...) approach to neoliberalism do not respond to any sort of neoliberal “sympathies”, but to another kind of problems-mainly analytical-.

Preoccupation with multiparty aggregative democracy in Africa has produced superficial forms of political/electoral choice-making by subjects that deepen pre-existing ethnic and primordial cleavages. This is because the principles of the multiparty system presuppose that decision-making through voting should be the result of a mere aggregation of pre-existing, fixed preferences. To this kind of decision-making, I propose deliberative democracy as a supplementary approach. My reason is that deliberation, beyond mere voting, should be central to decisionmaking and that, for a decision to (...) be legitimate, it must be preceded by deliberation, not merely the aggregation of pre-existing fixed preferences. I agree with arguments that when adequate justifications are made for claims/demands/conclusions, deliberation has the potential to have a salutary effect on people’s opinions, transform/evolve preferences, better inform judgments/voting, lead to increasingly ‘common good’ decisions, have moral educative power, place more burden of account-giving on public officers, and furnish subjects/losers/outvoted with justifications for collectively binding decisions. I argue that a deliberative turn in politics in Africa will have a mitigating effect on tribal and money politics. (shrink)

This article examines new patterns of workplace inequality that emerge as transgender people are incorporated into the global labor market. Drawing on in-depth interviews with 41 transgender call center employees in the Philippines, I develop the concept “purple-collar labor” to describe how transgender workers—specifically trans women—are clustered, dispersed, and segregated in the workplace and how their patterned locations in social organizational structures serve a particular value-producing function. These patterned inclusions, I argue, come with explicit and implicit interactional expectations about how (...) “trans” should be put to work in the expansion and accumulation of global capital. In this way, the study examines the production and extraction of queer value and the folding of trans women’s gendered performances into commercial exchange. Data show how the affective labor of transgender employees is used to help foster productivity, ease workplace tensions, and boost employee morale. This study of transgender employment experiences opens new lines of inquiry for understanding gender inequalities at work, and it builds on scholarship that combines political economy approaches with transgender studies.

Kant’s emphasis on the immorality of lying even to a murderer at the door who is asking about a victim hidden inside has drawn criticism ever since. The example originally given by Constant has been read as the thread of morality by totalitarian ruthlessness.

Nonetheless, this article tries to argue that Kant is right, (...) especially since the rise of post-truth politics.

ObjectivesIn 2015, the Province of Quebec, Canada passed a law that allowed voluntary active euthanasia. Palliative care stakeholders in Canada have been largely opposed to euthanasia, yet there is little research about their views. The research question guiding this study was the following: How do palliative care physicians in Quebec position themselves regarding the practice of VAE in the context of the new provincial legislation?MethodsWe used interpretive description, an inductive methodology to answer research questions about clinical practice. A total of (...) 18 palliative care physicians participated in semistructured interviews at two university-affiliated hospitals in Quebec.ResultsParticipants positioned themselves in opposition to euthanasia. Their justifications were framed within their professional commitment to not hasten death, which sat in tension with the value of patients’ autonomy to choose how to die. Participants described VAE as unacceptable if it impeded opportunities to evaluate and alleviate suffering. Further, they contested government rhetoric that positioned VAE as a way to improve end-of-life care. Participants felt that VAE would diminish the potential of palliative care to relieve suffering. Dilemmas were apparent in their narratives, about reconciling respect for patient autonomy with broader palliative care values, and the value of accompanying and not abandoning patients who make requests for VAE while being committed to neither prolonging nor hastening death.ConclusionsThis study provides insight into nuanced positions of experienced palliative care physicians in Quebec and confirms expected tensions between an important stakeholder and the practice of VAE as guided by the new legislation.

Given a consequence relation in many-valued logic, what connectives can be defined? For instance, does there always exist a conditional operator internalizing the consequence relation, and which form should it take? In this paper, we pose this question in a multi-premise multi-conclusion setting for the class of so-called intersective mixed consequence relations, which extends the class of Tarskian relations. Using computer-aided methods, we answer extensively for 3-valued and 4-valued logics, focusing not only on conditional operators, but also on what we (...) call Gentzen-regular connectives. For arbitrary N-valued logics, we state necessary and sufficient conditions for the existence of such connectives in a multi-premise multi-conclusion setting. The results show that mixed consequence relations admit all classical connectives, and among them pure consequence relations are those that admit no other Gentzen-regular connectives. Conditionals can also be found for a broader class of intersective mixed consequence relations, but with the exclusion of order-theoretic consequence relations. (shrink)

Aunque fueron muchos los intentos en la modernidad de superar el dualismo cuerpo y mente, las teorías filosóficas del lenguaje en muchos casos lo reintrodujeron de manera sutil pero no menos eficaz. El artículo discute varios teoremas para pensar la materialidad del signo y muestra la preponderancia, desde Kierkegaard hasta el estructuralismo post-Saussuriano, de pensar la materialización como algo necesario, pero arbitrario en su modalidad. En esta concepción, el cuerpo del lenguaje no es solamente aquello que se puede sino aquello (...) que se debe poder modificar: la corporalidad de la expresión es lo que debe poder ser absolutamente sustituible para conservar la unidad del sentido. Sin embargo, en muchos casos, el sentido emerge precisamente de la singularidad insustituible, de la configuración de los signos en la poesía o de la gestualidad inimitable del actor. El articulo argumenta en favor de introducir, en esta discusión, la distinción fenomenológica entre Kó'rper y Leib, que - como Husserl sugirió - también puede pueden pensarse según la diferencia entre lo representable y lo irrepresentable, entre lo que no tiene papel constituyente y que desde luego puede ser sustituido, y lo que permite ser representado por otro porque es insustituible. Although in the modern age there were plenty of attempts to overcome the mind-body dualism, its philosophical theories of languages reintroduced it in a subtle but not less effective way. In this article several theorems to think on the materiality of the sign are discussed, and the preponderance, from Kierkegaard to the post-Saussurean structuralism, of thinking the materialization as something necessary but arbitrary in its modality, is shown. The body of language under this understanding is not only that which can be modified, but that which must be modifiable: the corporeality of the utterance must be substitutable in order to preserve the unit of meaning. Nevertheless, in many cases, the meaning comes precisely from the unsubstitutable singularity, from the configuration of the signs in poetry or from the inimitable actor's gestures. The article argues for introducing in this discussion the phenomenological distinction between Kórper and Leib, which - as Husserl suggested - may also be thought from the difference between the representable and the irrepresentable, between what does not have a constituent role and hence can be substituted, and what allows to be represented by another because it is unsubstitutable.

In The Experience of Injustice, the French philosopher Emmanuel Renault opens an important new chapter in critical theory. He brings together political theory, critical social science, and a keen sense of the power of popular movements to offer a forceful vision of social justice. Questioning normative political philosophy’s conception of justice, Renault gives an account of injustice as the denial of recognition, placing the experience of social suffering at the heart of contemporary critical theory. Inspired by Axel Honneth, Renault (...) argues that a radicalized version of Honneth’s ethics of recognition can provide a systematic alternative to the liberal-democratic projects of such thinkers as Rawls and Habermas. Renault reformulates Honneth’s theory as a framework founded on experiences of injustice. He develops a complex, psychoanalytically rich account of suffering, disaffiliation, and identity loss to explain these experiences as denials of recognition, linking everyday injustice to a robust defense of the politicization of identity in social struggles. Engaging contemporary French and German critical theory alongside interdisciplinary tools from sociology, psychoanalysis, socialist political theory, social-movement theory, and philosophy, Renault articulates the importance of a theory of recognition for the resurgence of social critique.

L’argument de base de cet article est que le débat consensuel n’a pas été une notion très significative jusqu’à présent parce que le consensus n’a pas été étudié de manière approfondie en tant que concept et que la délibération n’a pas été étudiée précisément en termes de sa propension à parvenir à un accord commun. En particulier, la délibération et les problèmes qui en découlent n’ont pas été classées en plusieurs niveaux afin d’exposer les différents défis qui se posent lorsque (...) l’on tente de parvenir à un accord et les types d’approches délibératives impliquées dans chaque catégorie. La présente recherche propose une telle catégorisation dans le but de clarifier davantage le débat. (shrink)

Several factors have been put forward to explain the variability of moral judgments for superficially analogous moral dilemmas, in particular in the paradigm of trolley cases. In this paper we elaborate on Mikhail's view that (i) causal analysis is at the core of moral judgments and that (ii) causal judgments can be quantified by linguistic methods. According to this model, our moral judgments depend both on utilitarian considerations (whether positive effects outweigh negative effects) and on a representation of the causal (...) structure of the action (whether the negative effects are essentially side-effects rather than main goals). However, the exact contribution of each factor, as well as the precise way in which causal considerations interact with utilitarian considerations, has yet to be quantified and investigated. We present several variations on trolley dilemmas in which subjects had to assess the morality of the action and to evaluate their preference between two competing descriptions of the scene (..

ABSTRACT While the first generation of the so-called Frankfurt School has promoted a strong interconnection between social critique and knowledge of the social world, contemporary critical theory seems to consider that epistemological issues don’t deserve anymore consideration. Is it really possible to elaborate a convincing theory of social critique without taking seriously the various links between social critique and knowledge? This article argues that the answer is no. In a first step, it recalls the ways in which the philosophical debate (...) about social critique is currently articulated and how it disconnects social critique and knowledge. One of the reasons for such a disconnection relates to a vision of politics as consisting mainly in a conflict between normative principles, notably between conceptions of social justice. This vision of politics is criticized in the second step of this paper. A second reason, examined in the third part of the paper, relates to the risk of epistemic violence. The shared but questionable assumption is that any sociological or philosophical attempt to produce knowledge would necessarily lead to epistemic violence rather than to epistemic empowerment.

In this essay, I will argue that the discourse over the existence of the Devil/Satan has no place among the religious cultures in sub-Saharan Africa. This may be contrasted with the numerous efforts in the dominant philosophy of religion tradition in the Anglo-American sphere, where efforts toward the establishing grounds for the existence of God have occupied and commanded so much attention. On the other hand, it seems to have been taken for granted that Devil, the One who is antagonistic (...) of God, among the Abrahamic monotheisms, is assumed to exist and does not require serious intellectual elaboration. For my aim, I explore the traditional Yorùbá and Igbo religious cultures to foreground that God. In the traditional belief system of these two religious cultures, there is no place to entertain the idea of a necessarily antagonistic entity, popularly called the Devil.Whereas I recognise previous scholarships that have served to show that Èṣù and Ekwensu in each of these religious cultures are not synonymous with Devil in the Abrahamic monotheisms, I move beyond these to establishing the ontological framework which endorses the absence of a Devil, even when evil lingers in the world. If the argument that there is no Devil/Satan in these religious cultures is proved valid, then it is pertinent to tender the origin and persistence of evil in the world. For this task, I explore the process-relational character of Yorùbá and Igbo theology to reinforce my conviction concerning the peoples’ belief in the existence of God in Chukwu and Olódùmarè, the presence of evil in the world, without encountering the philosophical problem of evil.

In 20th century thinking, few concepts have provoked as many misunderstandings as Merleau-Ponty’s notion of ‘Flesh’. Such misunderstandings (of which the article sketches the outline of an archaeology) rest on the initial assumption that the Flesh has to be derived from the body. The article suggests that the dominant readings of the Flesh can be organized along what could respectively be called the scenario of propriety and the scenario of expansion, beyond which a third way comes into view which does (...) not think Flesh as plenitude, but as an interstitial fabric. In this sense, the genesis of the last ontology of the Flesh is neither to be found in Husserl or in a simple anti-Sartrianism, but in a fecund and still underestimated reading of Saussure’s notion of the diacritics. The ontological turn of the last writings can thus only be understood on the grounds of the expressive turn from the intermediate period. (shrink)

Recent debates about aesthetics are characterized by a partly intentional, but also partly involuntary, vagueness. Whether it be aestheticisation or anesthetisation, articisation or desartification: what is upheld or deplored under one and the same label in fact designates rather different things. The paper makes a suggestion as to how the field could be reorganized. Taking heed of what political theory discusses as the “political difference” between “politics” and “the political”, the aim is to examine what would be gained by working (...) with an “aesthetic difference” that does not straightforwardly equate “the aesthetic” with “art”, and “the aesthetic” with the totality of sensuous-aisthetic processes. An aesthetic thinking would then amount to a thinking that does justice to these inner polarities and remains faithful to the ambiguity of its objects. (shrink)

In his plea for consensual democracy in Africa, Kwasi Wiredu recommends unanimity about what is to be done, not what ought to be done, or unanimity on action rather than unanimity of values, beliefs and opinion. I caution the use of this procedural instrument by showing that some issues are so value-laden that a group decision cannot be value-neutral. It may sometimes be more productive to entertain value differences to keep them from going underground and becoming dangerous. However, the ability (...) to locate some common interest or ground seems to be crucial for such value confrontation. (shrink)
