In a topic as controversial as the Turin Shroud, it is always surprising to note that there remains a large area of consensus among scholars who hold opposite opinions on the origin of this piece of fabric. According to the consensus view, neither science nor history can prove that the Turin Shroud shows signs of the Resurrection of Jesus of Nazareth. However, the reasons provided for this important claim are not convincing, especially in light of recent developments in historiography and (...) analytic philosophy. (shrink)

What happened to the theories of Europe developed by the Enlightenment? Following a pluridisciplinary perspective, this book examines the way in which the projects conceived in the 18th century were reinvested both in the founding texts of the European Union and in contemporary political theory.

É bem sabido que a estética de Kant está estruturada intersubjetivamente, porque ele honra a reivindicação do gosto pela universalidade. No entanto, o fundamento transcendental desta universalidade compartilhada é uma base suprasensível tida por certa, mas que não pode ser trazida diretamente para dentro da experiência comunicativa. O apelo kantiano à estrutura sintética a priori do juízo estético também remove-o da esfera da interação pessoal observável. Esta estratégia argumentativa expõe-no a desafios céticos e gera referências inacessíveis às representações internas (sejam (...) elas intuições, categorias do entendimento ou idéias racionais). Não é suficiente, como faz Kant, propor uma descrição da experiência estética que seja subjetivamente plausível e, a partir disso, reivindicar sua validade intersubjetiva. É indispensável encarnar a intersubjetividade no comportamento e na linguagem. Na intersubjetividade prática, lida-se com as atitudes estéticas em um modo concreto e acessível, sem depender de pressupostos mentalistas como fundamento. Termos conceituais como 'agradável', 'belo', 'sublime', 'feio', 'universalidade' adquirem novo significado em um contexto interativo e reivindicações estéticas são testadas em um modelo dialógico de jogo semântico.

This volume is dedicated to the topic of the human evaluation and interpretation of animals in ancient and medieval cultures. From a transcultural perspective contributions from Assyriology, Byzantine Studies, Classical Archaeology, Egyptology, German Medieval Studies and Jewish History look into the processes and mechanisms behind the transfer by people of certain values to animals, and the functions these animal-signs have within written, pictorial and performative forms of expression.

Significant disagreement remains in ethics about the duties we have towards wild animals. This paper aims to mediate those disagreements by exploring how they are supported by, or diverge from, the common-sense ethical principles of non-maleficence, beneficence, autonomy and justice popular in medical ethics. We argue that these principles do not clearly justify traditional conservation or a ‘hands-off ’ approach to wild-animal welfare; instead, they support natural negative duties to reduce the harms that we cause as well as natural positive (...) duties to promote the welfare of wild animals.

Viewing emotion from an evolutionary perspective, researchers have argued that simple responses to affective stimuli can be triggered without mediation of cognitive processes. Indeed, findings suggest that positively and negatively valenced stimuli trigger approach and avoidance movements automatically. However, affective stimulus–response compatibility phenomena share so many central characteristics with nonaffective stimulus–response compatibility phenomena that one may doubt whether the underlying mechanisms differ. We suggest an “affectively enriched” version of the theory of event coding (TEC) that is able to account for (...) both affective and nonaffective compatibility, and that can account for the observation that both types of compatibility seem to be modulated by goals and intentions. Predictions from the model are tested in an experiment where participants carried out approach and avoidance responses to either the valence or the orientation of emotionally charged pictures. Under affective instruction the positive-approach/negative-avoid mapping yielded faster responses than the positive-avoid/negative-approach mapping, but no such effect was observed under spatial instruction. Conversely, spatial compatibility effects were obtained under spatial, but not under affective instruction. We conclude that affective and nonaffective compatibility effects reflect the same mechanism. (shrink)

Political philosophy was once dominated by discussion of the virtues of character and their importance to the good life and the good society. Contemporary political philosophers, however, following the towering influence of John Rawls, have primarily focused on a single virtue of institutions: justice, while largely avoiding controversial claims about the good life. As a result, political philosophy lacks a unified account of the virtues of institutions and the virtues of character. More importantly, we lack an understanding of the connection (...) between the just society and the good life. This book begins to mend this broken seam, which, on reflection, lies at the heart of our deepest political problems. The book’s central argument is that the virtues of character require institutions, while good institutions enable persons to live together virtuously. Political institutions are a necessary precondition for the moral agency exhibited by the virtues. But good institutions enable virtue to grow, while helping to constrain the excesses of vice. On this view, justice emerges primarily as a virtue of character, not institutions. The just person balances conformity to existing institutional norms with practically wise reforms. Ultimately, this book concludes that the just society and the good life are linked through the common good of virtuous activity within the shared institutions of a political community. (shrink)

Georges Palante, figure oubliée de la sociologie naissante, fut le théoricien d'une révolte intransigeante de l'individu face aux mécanismes oppressifs déployés par la société. Lecteur de Nietzsche et de Schopenhauer, ennemi déclaré des durkheimiens, socialiste non marxiste, farouche défenseur de l'individu, Georges Palante est un penseur iconoclaste qui n'a eu de cesse de développer une éthique individualiste et libertaire en vue du plein épanouissement des facultés et des potentialités individuelles. Cependant, par un étrange paradoxe, l'éthique palantienne prend sa source dans (...) une philosophie pessimiste qui offre à la révolte un caractère tragique et indompté : elle doit avoir lieu et ce, malgré la certitude de sa défaite. C'est précisément ce paradoxe que cet ouvrage entend questionner tout en offrant une introduction à l'oeuvre de Georges Palante. Interroger la possibilité d'une révolte pessimiste, c'est interroger ce moment de l'insoumission et de la désobéissance propre à la condition humaine. Palante ouvre la voie qui inscrit la révolte et le mouvement du refus dans la constitution même de l'homme. Avec Albert Camus, Palante pourrait affirmer : "Qu'est-ce qu'un homme révolté? Un homme qui dit non. Mais s'il refuse, il ne renonce pas : c'est aussi un homme qui dit oui dès son premier mouvement.". (shrink)

Over the years, phenomenology has provided illuminating descriptions of discrimination, with its mechanisms and effects being thematised at the most basic levels of embodiment, (dis)orientation, selfhood, and belonging. What remains somewhat understudied is the lived experience of the discriminator. In this paper I draw on Husserl's phenomenological account of normality to reflect on the ways in which we discriminate at the prereflective levels of perceptual experience and bodily being. By critically reflecting on the intentional structures undergirding discriminatory practices, I argue (...) that discrimination is characteristic of a naïve normalising attitude which is habitually interested in securing a familiar experience of a static normality. I first demonstrate how this attitude problematically tends to reproduce, enforce, and further sediment discriminatory and exclusionary norms. Further, I provide an internal critique which problematises discrimination—without recourse to external normative standards—on three fronts: as epistemically unproductive, experientially obscuring, and normatively non-instantiating. In discriminatory acts we see an abnormal refusal to enrich, revise, and genetically establish new normative commitments, new ways of seeing, and a new normality. (shrink)

Our lives today are oppressed by the demand that we live, feel and experience with ever greater intensity. We are enticed to try exotic flavours and smells; urged to enjoy a wide range of sexual experiences; pushed to engage in extreme sports and recreational drugs - all in the pursuit of some new, unheard-of intensity. Tristan Garcia argues that such intensity rarely lives up to its promise. It always comes at a price: one that defines the ethical predicament of (...) contemporary life. The notion of intensity was the hidden key to Garcia's landmark book Form and Object. In The Life Intense, the first part of his ambitious Letting Be trilogy, he begins to develop it in detail. This first book focuses on ethics; the forthcoming two books look at politics and metaphysics respectively."--Publisher's description. (shrink)

In this paper we develop a differential analogue of o-minimal cell decomposition for the theory CODF of closed ordered differential fields. Thanks to this differential cell decomposition we define a well-behaving dimension function on the class of definable sets in CODF. We conclude this paper by proving that this dimension is closely related to both the usual differential transcendence degree and the topological dimension associated, in this case, with a natural differential topology on ordered differential fields.

Kosmopolitismus wird oft als elitäre Geisteshaltung angesehen. Diese Studie geht allerdings von der These aus, dass er auch ein gesellschaftliches und politisches Engagement begründet hat. Es wird untersucht, wie Weltbürger grenzüberschreitend gemeinsame Positionierungen entwickelten und umsetzten. Im Fokus steht der Umgang mit dem kosmopolitischen Erbe der Aufklärung im 19. und frühen 20. Jahrhundert zwischen Deutschland und Frankreich. 0Auf der Suche nach Transferphänomenen, Spannungen und Verflechtungen werden entscheidende Umbruchsphasen beleuchtet: die Debatten des Revolutionszeitalters, die Erneuerung des Internationalismus nach 1848/1849, das Wechselverhältnis (...) von Nationalismus und Universalismus um 1871, die Friedensbewegung vor 1914 und der Versuch, nach dem Krieg eine friedliche Weltordnung weltbürgerlich zu begründen. Die Aufarbeitung kosmopolitischer Einstellungen bietet Einsicht in einen deutsch-französischen Lernprozess, der die Durchsetzung einer geteilten Demokratieauffassung begünstigt hat. (shrink)

It is well known that Kant’s aesthetics is framed intersubjectively because he upholds the claim of taste to universality. However, the transcendental foundation of this shared universality is a supersensible ground which is taken for granted but which cannot be brought directly into communicative experience. Kant’s reliance on the synthetic a priori structure of aesthetic judgment also removes it from the sphere of observable personal interaction. This argumentative strategy exposes it to skeptical challenge and generates inaccessible references to inner representations (...) (be they intuitions, categories of the understanding or rational ideas). It is not sufficient, as Kant did, to propose a description of aesthetic experience that is subjectively plausible and thereby claim its intersubjective validity. It is indispensable to embody intersubjectivity in behavior and language. In practical intersubjectivity, aesthetic attitudes are dealt with in a concrete and accessible manner without relying on mentalistic assumptions as a foundation. Conceptual terms such as ‘agreeable’, ‘beauty’, ‘sublime’, ‘ugly’, ‘universality’ acquire new meaning. (shrink)

Criteria of historical assessment are applied to the Turin Shroud to determine which hypothesis relating to the image formation process is the most likely. To implement this, a ‘Minimal Facts’ approach is followed that takes into account only physicochemical and historical data receiving the widest consensus among contemporary scientists. The result indicates that the probability of the Shroud of Turin being the real shroud of Jesus of Nazareth is very high; historians and natural theologians should therefore pay it increased attention.

Les logiciels d’aide à la décision basés sur des techniques d’intelligence artificielle sont de plus en plus utilisés dans le domaine de la justice. Or ces techniques nécessitent souvent d’accéder à de grandes quantités d’informations personnelles afin de réaliser un apprentissage de qualité. En France, le cadre légal semble aujourd’hui favorable à l’ouverture des jugements, pourvu que la vie privée des personnes concernées soit respectée. Cependant, la protection des données personnelles destinées à être publiées reste difficile techniquement. Cet article a (...) pour objectif de décrire une attaque minimaliste qui a été réalisée en 2014 sur un jeu de données protégé par l’application d’un algorithme de pseudonymisation.

L'objectif de cet article est de montrer dans quelle mesure, depuis la fin des années 1980, les théories de la mondialisation culturelle, nées d'une convergence dans le champ académique anglo-saxon entre certains tenants des Cultural Studies, de l'anthropologie et de la sociologie, ont marqué une rupture dans la façon d'appréhender les enjeux de l'internationalisation des médias. Nous appuyant sur quelques-uns des principaux textes ayant donné corps à ces théories de la mondialisation, nous retraçons les principaux déplacements du centre de gravité (...) de l'analyse qu'elles opèrent. Prenant acte des apports de ces théories pour la compréhension des processus d'appropriation des flux transnationaux, cet article souligne aussi leurs limites et conclut à la nécessité d'inclure les perspectives de l'économie politique dans l'étude des processus de transnationalisation pour que ceux-ci soient appréhendés dans toute leur complexité.The objective of this paper is to show how, since the late 1980s, theories of cultural globalization, born of a convergence in the Anglo-Saxon academic field between some proponents of cultural studies, anthropology and sociology, marked a break in the way of understanding issues of internationalization of the media. Drawing on some of the main texts that gave substance to these theories of globalization, we trace the main movements of center of gravity analysis they operate. Acknowledging the contributions of these theories for understanding the process of appropriation of transnational flows, this article also highlights limitations and concludes with the need to include the perspectives of political economy in the study of transnational processes that they are apprehended in all their complexity.

Hydraulic fracturing ('fracking') has enabled the recovery of previously inaccessible resources and rendered new areas of the underground 'productive'. While a number of studies in the US and UK have examined public attitudes toward fracking and its various impacts, how people conceptualise the deep underground itself has received less attention. We argue that views on resources, risk and the deep underground raise important questions about how people perceive the desirability and viability of subterranean interventions. We conducted day-long deliberation workshops (two (...) in each country), facilitating discussions among diverse groups of people on prospective shale extraction in the US and UK. Themes that emerged in these conversations include seeing the Earth as a foundation; natural limits (a greater burden than the subsurface can withstand versus simply overuse of natural resources); and ideas about the fragility, instability and opacity of the deep underground. We find that concerns in both countries were not limited to specific, localised impacts but also addressed ecosystem links between surface and subsurface environments and broader questions about the use, identification and value of natural resources.

Gillian Russell has recently proposed counterexamples to such elementary argument forms as Conjunction Introduction and Identity. These purported counterexamples involve expressions that are sensitive to linguistic context—for example, a sentence which is true when it appears alone but false when embedded in a larger sentence. If they are genuine counterexamples, it looks as though logical nihilism—the view that there are no valid argument forms—might be true. In this paper, I argue that the purported counterexamples are not genuine, on the grounds (...) that they equivocate. Having defused the threat of logical nihilism, I argue that the kind of linguistic context sensitivity at work in Russell’s purported counterexamples, if taken seriously, far from leading to logical nihilism, reveals new, previously undreamt-of valid forms. By way of proof of concept I present a simple logic, Solo-Only Propositional Logic, designed to capture some of them. Along the way, some interesting subtleties about the fallacy of equivocation are revealed. (shrink)

Cet article décrit et analyse du point de vue de leurs évolutions majeures, les finalités des formations en alternance des maisons familiales rurales, une des principales institutions privées de l’enseignement agricole technique en France. Cette pédagogie de l’alternance est issue du syndicalisme agricole qui a défini les modes d’intervention des agents de formation, appelés les moniteurs. L’alternance, construite au départ contre l’enseignement primaire public, avait pour principal but de restaurer la famille paysanne en tant qu’instance éducative légitime, considérée comme détentrice (...) du monopole de la transmission des savoirs agricoles. Toutefois, à partir des années 1960, cette finalité initiale disparaît. Avec la massification scolaire, les formations en alternance jouent désormais un rôle d’école de la seconde chance oscillant entre une fonction de professionnalisation et une fonction de remédiation scolaire. Au cours d’une troisième période, identifiée à partir des années 1990, au moment de la création des maisons familiales urbaines, ces deux fonctions vont se rejoindre, ce dont témoigne l’évolution du rôle de moniteur : il devient un adulte référent et un « tuteur » pour des jeunes en difficulté se préparant à entrer dans la vie d’adulte.

Traditional whistleblowing theories have purported that whistleblowers engage in a rational process in determining whether or not to blow the whistle on misconduct. However, stressors inherent to whistleblowing often impede rational thinking and act as a barrier to effective whistleblowing. The negative impact of these stressors on whistleblowing may be made worse depending on who engages in the misconduct: a peer or advisor. In the present study, participants are presented with an ethical scenario where either a peer or advisor engages (...) in misconduct, and positive and the negative consequences of whistleblowing are either directed to the wrongdoer, department, or university. Participant responses to case questions were evaluated for whistleblowing intentions, moral intensity, metacognitive reasoning strategies, and positive and negative, active and passive emotions. Findings indicate that participants were less likely to report the observed misconduct of an advisor compared to a peer. Furthermore, the findings also suggest that when an advisor is the source of misconduct, greater negative affect results. Post-hoc analyses were also conducted examining the differences between those who did and did not intend to blow the whistle under the circumstances of either having to report an advisor or peer. The implications of these findings for understanding the complexities involved in whistleblowing are discussed. (shrink)

Cultural capital and hegemonic masculinity are two concepts that have received intense attention. While both have received serious consideration, critique and analysis, the context or field-specificity of each is sometimes ignored. They have been used in a diversity of ways. Using ethnographic and interview data from a US male bodybuilding community, this study highlights one useful employment. Hegemonic masculinity takes different shapes in different fields of interaction, acting as a form of cultural capital: gender capital. Inherent in this discussion are (...) the cultural contradictions apparent among individuals striving for either physical or ideological embodiments of gender capital. Individuals can attempt to embody hegemonic idealizations, but bodies are not only inscribed with gender, inscriptions are read, and read differently by different social actors and in different settings. The capacity of gender capital to remain elusive is precisely what enables gender practices and projects like bodybuilding to retain passionate participation. (shrink)

Data subject rights provide data controllers with obligations that can help with transparency, giving data subjects some control over their personal data. To date, a growing number of researchers have used these data subject rights as a methodology for data collection in research studies. No one, however, has gathered and analysed different academic research studies that use data subject rights as a methodology for data collection. To this end, we conducted a systematic literature review that searched, compiled, and analysed 32 (...) academic studies that use data subject rights as a data collection method. We find that the right of access is the most commonly-used data subject right by researchers, most studies are interested in measuring data subject rights compliance, and that a variety of difficulties exist in conducting research studies with data subject rights. We conclude that researchers should explore other data subject rights for alternative purposes, ease the process of exercising data subject rights, and improve the scalability of these studies.

A great need for systematic evaluation of ethics training programs exists. Those tasked with developing an ethics training program may be quick to dismiss the value of training evaluation in continuous process improvement. In the present effort, we use a case study approach to delineate how to leverage formative and summative evaluation measures to create a high-quality ethics education program. With regard to formative evaluation, information bearing on trainee reactions, qualitative data from the comments of trainees, in addition to empirical (...) findings, can ensure that the training program operates smoothly. Regarding summative evaluation, measures examining trainee cognition, behavior, and organization-level results provide information about how much trainees have changed as a result of taking the ethics training. The implications of effective training program evaluation are discussed. (shrink)

What is the relationship between justice as an individual virtue and justice as an institutional virtue? The latter has been exhaustively explored by political philosophers, whereas the former remains underexplored in the literature on virtue ethics. This article defends the view that individual justice is logically prior to institutional justice, and argues that this view requires a conception of individual justice I call ‘justice as lawfulness’. The resulting view consists of three claims. First, just institutions are composed of the relations (...) between just persons. Second, the just person has a disposition to act in accordance with the legal and social norms (collectively, thenomoi) of the existing political tradition. Third, departures from thenomoirequire that the just person act with practical wisdom to reform thenomoiaccording to an implicit standard of justice in the political tradition. (shrink)

This article demonstrates how instructors of professionalism and ethics training programs can integrate a professional decision-making tool in training curricula. This tool can help trainees understand how to apply professional decision-making strategies to address the threats posed by a variety of psychological and environmental factors when they are faced with complex professional and ethical situations. We begin by highlighting key decision-making frameworks and discussing factors that may undermine the use of professional decision-making strategies. Then, drawing upon findings from past research, (...) we present the “SMART” professional decision-making framework: seeking help, managing emotions, anticipating consequences, recognizing rules and context, and testing assumptions and motives. Next, we present a vignette that poses a complex ethical and professional challenge and illustrate how each professional decision-making strategy could or should be used by characters in the case. To conclude, we review a series of educational practices and pedagogical tools intended to help trainers facilitate trainee learning, retention, and application of “SMART” decision-making strategies.

I present two counterexamples to the recently back-in-favour truth-tracking account of knowledge: one involving a true belief resting on a counterfactually robust delusion, one involving a true belief acquired alongside a bunch of false beliefs.

The notion of rigidity looms large in philosophy of language, but is beset by difficulties. This paper proposes a simple theory of rigidity, according to which an expression has a world-relative semantic property rigidly when it has that property at, or with respect to, all worlds. Just as names, and certain descriptions like The square root of 4, rigidly designate their referents, so too are necessary truths rigidly true, and so too does cat rigidly have only animals in its extension. (...) After spelling out the theory, I argue that it enables us to avoid the headaches that attend the misbegotten desire to have a simple rigid/non-rigid distinction that applies to expressions, giving us a simple solution to the problem of generalizing the notion of rigidity beyond singular terms.
