Depuis la fin de la guerre froide, les recherches sur la gauche américaine se sont multipliées, parmi lesquelles différents ouvrages consacrés aux militantes africaines-américaines, qui démontrent combien le rôle qu’elles ont joué au sein du mouvement noir de libération américain a été trop longtemps passé sous silence. Keisha N. Blain, professeure d’histoire et d’Africana Studies à Brown University est l’auteure de Set the World on Fire: Black nationalist women and the global struggle for fr...

This paper defends the view that Newtonian forces are real, symmetrical and non-causal relations. First, I argue that Newtonian forces are real; second, that they are relations; third, that they are symmetrical relations; fourth, that they are not species of causation. The overall picture is anti-Humean to the extent that it defends the existence of forces as external relations irreducible to spatio-temporal ones, but is still compatible with Humean approaches to causation (and others) since it denies that forces are a (...) species of causation.

The academic path of Jean Gayon (1949–2018) follows in the wake of the “French style” in epistemologyEpistemology, but he is also one of the first representatives of philosophy of biology in France. In the light of this double philosophical heritage, this chapter re-examines the relations between the works of Gayon, the tradition in which he first studied, and the one he later adopted, but not without reservations. Tracing his intellectual journey, this article explores why he naturally appears as a Canguilhemian, (...) a view against which he defends himself. Attending to the connexions that he established with the philosophers of biology will bring to light the growing tension that inhabits him, from the middle of the 1980s onwards, and which led him to identify some of the limits inherent to theHistorical epistemology matrix of historical epistemologyGayon, JeanOn historical epistemology, without disowning his first philosophical tradition. Finally, in an attempt to reconcile two approaches, I will underline the emergence in the thought of Jean Gayon of a third way seeking to overcome the opposition between a “unitarian” style that seeks to make a clear break with the history of scienceHistory of science and its philosophical past, and the “dualist” style which tends to stay above scientific debates, and which accepts a clear distinction between the work of science and the work of philosophy. Reuniting the history and the philosophy of the sciences, privileging the long durée and depths of history, where the problems of biology unfold, while also recognizing the value of analysing the conceptual puzzles which structure the contemporary life sciences, the oeuvre of Jean Gayon illustrates the complementary character of these disciplines.

The relativistic revolution led to varieties of neo-Kantianism in which constitutive principles define the object of scientific knowledge in a domain-dependent and historically mutable manner. These principles are a priori insofar as they are necessary premises for the formulation of empirical laws in a given domain, but they lack the self-evidence of Kant’s a priori and they cannot be identified without prior knowledge of the theory they purport to frame. In contrast, the rationalist endeavors of a few masters of theoretical (...) physics have led to comprehensibility conditions that are easily admitted in a given domain and yet suffice to generate the theory of this domain. The purpose of this essay is to compare these two kinds of relativized a priori, to discuss the nature of the comprehensibility conditions, and to demonstrate their effectiveness in a modular conception of physical theories.

This article presents, an analysis of the opinions of assurance providers regarding the quality and the limitations of sustainability reports and their recommendations to improve them using the Global Reporting Initiative as a framework. The qualitative content analysis of 301 assurance statements for sustainability reports from mining and energy companies provides a comprehensive view of the main outcomes of the assurance process, including its limitations, the application of the GRI principles and suggestions for improving sustainability reports. Taking into account the (...) perceptions of practitioners a priori well informed on the quality of sustainability reports—namely assurance providers—this paper complements the current literature on sustainability reporting and its assurance, including critical approaches that question the reliability of sustainability reports, stakeholder engagement and the accountability of reporting practices. This study contributes to the debates surrounding the quality of sustainability reports, the added value of assurance statements and the ethical issues underlying the assurance process. It also contains important practical implications for auditors, standardization organizations and stakeholders. (shrink)

This paper supports the personal data platform cooperative as a means of bringing about John Rawls’s favoured institutional realisation of a just society, the property-owning democracy. It describes personal data platform cooperatives and applies Rawls’s political philosophy to analyse the institutional forms of a just society in relation to the economic power deriving from aggregating personal data. It argues that a society involving a significant number of personal data platform cooperatives will be more suitable to realising Rawls’s principle of fair (...) equality of opportunity. (shrink)

The paper aims at clarifying the distinctions and relations between pain and suffering. Three negative theses are defended: 1. Pain and suffering are not identical. 2. Pain is not a species of suffering, nor is suffering a species of pain, nor are pain and suffering of a common (proximate) genus. 3. Suffering cannot be defined as the perception of a pain’s badness, nor can pain be defined as a suffered bodily sensation. Three positive theses are endorsed: 4. Pain and suffering (...) are categorically distinct: pain is a localised bodily episode, suffering is a non-localised affective attitude. 5. Suffering can be expressed, pains cannot. As a consequence, we can have compassion for the suffering of others, not for their pains. 6. The relation between pain and suffering is akin to the relation between danger and fear, injustice and indignation, wrongdoing and guilt: suffering is the correct reaction to pain. One upshot is that both the influential view that the experience of pain is incorrigible and the influential view that the ordinary conception of pain is paradoxical are false. (shrink)

In French mechanical treatises of the nineteenth century, Newton’s second law of motion was frequently derived from a relativity principle. The origin of this trend is found in ingenious arguments by Huygens and Laplace, with intermediate contributions by Euler and d’Alembert. The derivations initially relied on Galilean relativity and impulsive forces. After Bélanger’s Cours de mécanique of 1847, they employed continuous forces and a stronger relativity with respect to any commonly impressed motion. The name “principle of relative motions” and the (...) very idea of using this principle as a constructive tool were born in this context. The consequences of Poincaré’s and Einstein’s awareness of this approach are analyzed. Lastly, the legitimacy and significance of a relativity-based derivation of Newton’s second law are briefly discussed in a more philosophical vein. (shrink)

We study shared intentions in what we call “loose groups”. These are groups that lack a codified organizational structure, and where the communication channels between group members are either unreliable or not completely open. We start by formulating two desiderata for shared intentions in such groups. We then argue that no existing account meets these two desiderata, because they assume either too strong or too weak an epistemic condition, that is, a condition on what the group members know and believe (...) about what the others intend, know, and believe. We propose an alternative, pooled knowledge, and argue that it allows formulating conditions on shared intentions that meet the two desiderata. (shrink)

In this paper we study substantive assumptions in social interaction. By substantive assumptions we mean contingent assumptions about what the players know and believe about each other’s choices and information. We first explain why substantive assumptions are fundamental for the analysis of games and, more generally, social interaction. Then we show that they can be compared formally, and that there exist contexts where no substantive assumptions are being made. Finally we show that the questions raised in this paper are related (...) to a number of issues concerning “large” structures in epistemic game theory. (shrink)

We agree that external validity of social psychological experiments is a concern, we disagree these models are useless. Experiments, reconsidered from a situated cognition perspective and non-linearly combined with other methods allow grasping decision dynamics beyond bias outcomes. Dynamic insights regarding these processes are key to understand missing forces and bias in real-world social groups.

The theoretical literature on vertical relationships usually assumes that beliefs about secret contracts take specific forms. In a recent paper, Eguia et al. (Games Econ Behav 109:465–483,2018) propose a new selection criterion that does not impose any restriction on beliefs. In this article, we extend their criterion by generalizing it to risk-averse retailers, and we show that risk aversion modifies the size of the belief subsets that support each equilibrium. We conduct an experiment which revisits that of Eguia et al. (...) (Games Econ Behav 109:465–483,2018). We design a new treatment effect on equilibrium selection depending on the retailers’ risk sensitivity. Experimental results confirm the treatment effect: the more sensitivity there is towards risk, the more the equilibrium played is consistent with passive beliefs. In addition, extending Eguia et al.’s (Games Econ Behav 109:465–483,2018) criterion to risk-averse retailers improves its predictive power on the equilibria played, especially for a population of retailers with moderate to extreme risk aversion.

Apprendre, c'est d'abord élever et s'élever puisque, en français, apprendre a toujours le sens passif (s'instruire) et actif (instruire). Apprendre, c'est ensuite enseigner : il s'agit d'une éducation, intentionnelle, méthodique, programmée. Apprendre, c'est aussi former. Ce verbe correspond avant tout à l'apprentissage d'un métier. Apprendre, c'est enfin échanger, imiter, s'initier, apprendre à être. Tels sont les enjeux de cette réflexion sur les valeurs de l'éducation conçue comme apprentissage de l'humanité.

En dépit de sept lois intervenues entre 1988 et 2013 en matière de transparence dans la vie publique et de lutte contre la corruption, la France est caractérisée par un sentiment de banalisation des scandales politiques. Ces derniers, qui conduisent parfois à la démission ou à la condamnation d’un responsable politique, semblent d’abord revêtir une dimension « sacrificielle ». Or cette situation, qui aboutit à ne plus voir dans certains manquements éthiques des scandales politiques ou qui prive ceux-ci, lorsqu’ils éclatent, (...) de leur effet utile pour la construction de l’État de droit, est révélatrice d’une culture juridique française fondée sur une croyance en une « incarnation » du pouvoir. L’objet de l’article est dès lors d’expliquer les raisons de cette spécificité, avant de montrer que le système français promeut lui-même une distinction entre la fonction politique et son titulaire, et l’instauration d’un « censeur » au service de la première.

L'actualité sociolinguistique des Départements français de la Caraïbe et de l'Océan indien illustre les contradictions internes qui agitent les sociétés créoles. Elle souligne également la difficulté que rencontrent ces territoires pour envisager leurs rapports entre eux. L'action de l'État destinée à valoriser les langues et cultures régionales dans la République, a relancé le débat public sur la question linguistique dans les aires créolophones françaises. L'existence d'un ou plusieurs créoles, les modalités de son écriture, les critères de sa généralisation dans le (...) cadre de son enseignement comme langue, sont au coeur du débat. Les défenseurs du créole écrit chercheraient à substituer une langue déviante et savante aux langues vernaculaires, niant de fait les particularités linguistiques de chaque territoire au profit d'un espéranto créole. L'analyse du développement d'un mouvement de revendications linguistique et culturelle dans les aires créoles françaises montre l'existence d'une dynamique identitaire revisitée à partir de la diversité culturelle de ces territoiresFrom a sociolinguistic standpoint the French “Departments” of the Caribbean and the Indian Ocean currently illustrate internal contradictions within Creole societies. These territories are also confronted with difficulties in establishing relationships between themselves. State action destined to promote regional languages and cultures in France has renewed public debate on the linguistic issue in French Creole speaking areas. The existence of one or several varieties of Creole, their modes of writing, the criteria of their generalisation in the context of how they are taught as a language, are all at the very centre of the debate. It is possible that the defenders of written Creole try to substitute a deviant and academic language for vernacular languages thus denying in fact the linguistic particularities of each territory in favour of a kind of Creole esperanto. The analysis of the development of a linguistic and cultural movement claiming a better status in French Creole areas shows the existence of revisited identity dynamics from the cultural diversity in those territories.

The description of vision occurs in the Timaeus in 45b-47b, following a double pattern characteristic of this dialogue: The physicist first gives a mechanical explanation of sight that involves two fluxes of light, that of the eye and that of the body in the field of vision. He then goes on to give a functionalist explanation that puts vision at the source of the sciences of astronomy, mathematics, and even philosophy. In this complex passage of the Timaeus, vision is a (...) power that informs us how an affection, that gives rise to sensations, could give rise to knowledge. This article begins by investigating the main ideas in passage 45b-47b of the Timaeus and goes on to explain what is at stake in competing interpretations concerning the role of vision in thought in this particular passage. It argues that, through a constitutive dualism between the sensible and the intelligible – implying an epistemological gap – vision is an instrument towards the intelligible. (shrink)

L’œuvre majeure de Johannes Weiss, Die Predigt Jesu vom Reiche Gottes (1892) n’est le plus souvent mentionnée qu’à titre d’exemple d’une découverte exégétique qui n’aurait eu aucune conséquence, chez son auteur, en théologie dogmatique. Après avoir présenté dans leur contexte les thèses principales de cet écrit, l’article critique la représentation – héritée de Schweitzer – d’une « redécouverte » de l’eschatologie, et précise la limite de la proposition théologique de Weiss : si on ne saurait lui reprocher une réinterprétation des (...) représentations du Royaume de Dieu dans la prédication de Jésus, on peut regretter qu’il ne traite celui-ci que comme un thème de la prédication de Jésus, et non comme une relation constituant son identité même.

In biological systematics, as well as in the philosophy of biology, species and higher taxa are individuated through their unique evolutionary origin. This is taken by some authors to mean that monophyly is a (relational) property not only of higher taxa, but also of species. A species is said to originate through speciation, and to go extinct when it splits into two daughter species (or through terminal extinction). Its unique evolutionary origin is said to bestow identity on a species through (...) time and change, and to render species names rigid designators. Species names are thus believed to function just like names of supraspecific taxa. However, large parts of the Web of Life are composed of species that do not have a unique evolutionary origin from a single population, lineage or stem-species. Further, monophyly is an ambiguous concept if it is defined simply in terms of ‘unique evolutionary origin’. Disambiguating the concept by defining a monophyletic taxon as ‘a taxon that includes the ancestor and all, and only, its descendant’ renders monophyly inapplicable to species. At the heart of the problem lies a fundamental distinction between species and monophyletic taxa, where species form mutually exclusive reticulated systems, while higher taxa form inclusive hierarchical systems. Examples are given both at the species level and below to illustrate the problems that result from the application of the monophyly criterion to species. The conclusion is that the concepts of exclusivity and monophyly should be treated as non-overlapping: exclusivity marks out a species synchronistically, i.e. in the present time. Monophyly marks out clades (groups of species) diachronistically, i.e. within an historical dimension. (shrink)

We consider ω n -automatic structures which are relational structures whose domain and relations are accepted by automata reading ordinal words of length ω n for some integer n ≥ 1. We show that all these structures are ω-tree-automatic structures presentable by Muller or Rabin tree automata. We prove that the isomorphism relation for ω 2 -automatic (resp. ω n -automatic for n > 2) boolean algebras (respectively, partial orders, rings, commutative rings, non commutative rings, non commutative groups) is not (...) determined by the axiomatic system ZFC. We infer from the proof of the above result that the isomorphism problem for ω n -automatic boolean algebras, n ≥ 2, (respectively, rings, commutative rings, non commutative rings, non commutative groups) is neither a ${\mathrm{\Sigma }}_{2}^{1}-\mathrm{s}\mathrm{e}\mathrm{t}$ nor a ${\mathrm{\Pi }}_{2}^{1}-\mathrm{s}\mathrm{e}\mathrm{t}$ . We obtain that there exist infinitely many ω n -automatic, hence also ω-tree-automatic, atomless boolean algebras $\mathcal{B}_{n}$ , n ≥ 1, which are pairwise isomorphic under the continuum hypothesis CH and pairwise non isomorphic under an alternate axiom AT, strengthening a result of [14].

En tout généralité, le concept d’émergence capture une relation entre deux entités, un « émergent » E et sa « base d’émergence » B, de telle manière que l’on puisse affirmer que E dépend de B et que, malgré cette dépendance, E s’avère irréductible à B. Une façon classique de concrétiser cette idée est de considérer E comme un « tout » et B comme les « parties » de ce tout. Dans l’esprit de la maxime classique selon laquelle « (...) Le tout est plus que la somme de ses parties », l’émergence cristallise ainsi un double refus : celui de la simple assimilation du tout à ses parties, ainsi que celui de la radicale déconnexion entre le tout et ses parties. À cet égard, affirmer par exemple qu’une cellule vivante émerge d’une base moléculaire inerte sous-jacente revient à considérer que, d’une part, la nature de la cellule est bien dépendante de la nature des molécules qui la composent et que, d’autre part et malgré cette dépendance, certaines propriétés de la cellule ne peuvent être réduites aux propriétés de ces molécules. Ainsi posée, l’émergence se révèle un outil philosophique prometteur pour constituer et défendre une voie médiane entre le réductionnisme et le dualisme, positions selon lesquelles, respectivement, « le tout n’est que la somme de ses parties » et « le tout est hétérogène à ses parties ». Elle permet alors de faire droit à l’intuition selon laquelle les sciences comme la biologie ou la psychologie, ainsi que les objets que ces sciences étudient – par exemple les organismes ou l’« esprit » – témoignent d’une relative autonomie par rapport aux sciences étudiant les constituants élémentaires de la réalité naturelle. -/- Dans la présente entrée, après avoir introduit à l’idée générale de l’émergence et au projet philosophique initiateur de l’émergentisme, et après avoir fait recension de différents phénomènes possiblement émergents, nous tâchons d’élucider les déterminants historiques des différentes théories contemporaines de l’émergence. Dans un effort ensuite plus conceptuel, nous nous attachons à distinguer les différents sens dans lesquels une entité peut être considérée comme émergente. Nous concluons cette entrée en identifiant les apories majeures de l’émergentisme actuel dans sa version dominante. (shrink)
