Sorting of membrane proteins is generally mediated by cytosolic coats, which create a scaffold to form coated buds and vesicles and to selectively concentrate cargo by interacting with cytosolic signals. The classical paradigm is the interaction between clathrin coats and associated adaptor proteins, which cluster receptors with characteristic tyrosine and dileucine motifs during endocytosis. Clathrin in association with different sets of adaptors is found in addition at the trans-Golgi network and endosomes. Sequences similar to internalization signals also direct lysosomal and (...) basolateral sorting, which implicates related clathrin-adaptor coats in the respective sorting pathways. This review concentrates on the recognition of sorting signals by clathrin-associated adaptor proteins, an area of significant recent progress due to new methodological and conceptual approaches.

Normative accounts of the correctness of belief have often been misconstrued. The norm of truth for belief is a constitutive norm which regulates our beliefs through ideals of reason. I try to show that this kind of account can meet some of the main objections which have been raised against normativism about belief: that epistemic reasons enjoy no exclusivity, that the norm of truth does not guide, and that normativism cannot account for suspension of judgement.

Belief is not a unified phenomenon. In this paper I argue, as a number of other riters argue, that one should distinguish a variety of belief-like attitudes: believing proper - a dispositional state which can have degrees - holding true - which can occur without understanding what one believes - and accepting - a practical and contextual attitude that has a role in deliberation and in practical reasoning. Acceptance itself is not a unified attitude. I explore the various relationships and (...) differences between these doxastic attitudes, and claim that although acceptance is distinct from belief, it rests upon it, and is therefore a species of belief.

The thesis that mental content is normative is ambiguous and has many forms. This article deals only with the thesis that normativity is connected to our mental attitudes rather than with the content of the attitudes, and more specifically with the view that it is connected to belief. A number of writers have proposed various versions of a ‘norm of truth’ attached to belief. I examine various versions of this claim, and defend it against recent criticisms according to which this (...) norm lacks normative force, that it violates the principle that ‘ought implies can,’ and that it is viciously circular. I defend the view that we should distinguish the statement of the objective norm and the way it is regulated, and that this distinction can answer most of the criticisms of the norm of truth for belief.

The knowledge account of assertion (KAA) is the view that assertion is governed by the norm that the speaker should know what s/he asserts. It is not the purpose of this article to examine all the criticisms nor to try to give a full defence of KAA, but only to defend it against the charge of being normatively incorrect. It has been objected that assertion is governed by other norms than knowledge, or by no norm at all. It seems to (...) me, however, that a number of these criticisms are based on a number of misunderstandings of the notion of a norm and of the way it can regulated a given practice. Once we spell out in what sense knowledge can play a normative role in this context, the KAA appears much more plausible. (shrink)

This article discusses the arguments against associating epistemic responsibility with the ordinary notion of agency. I examine the various 'Kantian' views which lead to a distinctive conception of epistemic agency and epistemic responsibility. I try to explain why we can be held responsible for our beliefs in the sense of obeying norms which regulate them without being epistemic agents.

The identity theory of truth, according to which true thoughts are identical with facts, is very hard to formulate. It oscillates between substantive versions, which are implausible, and a merely truistic version, which is difficult to distinguish from deflationism about truth. This tension is present in the form of identity theory that one can attribute to McDowell from his views on perception, and in the conception defended by Hornsby under that name.

Religions “in the wild” are the varied set of religious activities that occurred before the emergence of organized religions with doctrines, or that persist at the margins of those organized traditions. These religious activities mostly focus on misfortune; on how to remedy specific cases of illness, accidents, failures; and on how to prevent them. I present a general model to account for the cross-cultural recurrence of these particular themes. The model is based on features of human psychology—namely, epistemic vigilance, the (...) set of systems whereby we evaluate the quality of information and of sources of information, and threat-detection psychology, the set of evolved systems geared at detecting potential danger in the environment. Given these two sets of systems, the dynamics of communication will favor particular types of messages about misfortune. This makes it possible to predict recurrent features of religious systems, such as the focus on nonphysical agents, the focus on particular cases rather than general aspects of misfortune, and the emergence of specialists. The model could illuminate not just why such representations are culturally successful, but also why people are motivated to formulate them in the first place. (shrink)

Sosa takes epistemic normativity to be kind of performance normativity: a belief is correct because a believer sets a positive value to truth as an aim and performs aptly and adroitly. I object to this teleological picture that beliefs are not performances, and that epistemic reasons or beliefs cannot be balanced against practical reasons. Although the picture fits the nature of inquiry, it does not fit the normative nature of believing, which has to be conceived along distinct lines.

This article examines Keith Lehrer's distinction between belief and acceptance and how it differs from other accounts of belief and of the family of doxastic attitudes. I sketch a different taxonomy of doxastic attitudes. Lehrer's notion of acceptance is mostly epistemic and at the service of his account of the "loop of reason", whereas for other writers acceptance is mostly a pragmatic attitude. I argue, however, that his account of acceptance underdetermines the role that the attitude of trust plays in (...) his analysis of reason. (shrink)

Le sceptique nous demande " Comment sais-tu que tu as deux mains? Peut-être rêves-tu, ou es-tu trompé par quelque Malin Génie? Peut-on même définir ce que c'est que la connaissance? Va savoir! " Lui rétorquer, comme le faisaient G.E. Moore et la tradition de la philosophie du sens commun : " Mais je sais bien que j'ai deux mains! " semble à la fois une pétition de principe et une bien mauvaise réponse. Le mieux, depuis que nous avons perdu le (...) souci de fonder nos croyance sur des raisons ultimes, serait, tout simplement, de ne pas se soucier des questions du sceptique. Ce que l'on sait dépend, nous dit-on, des circonstances, et toutes nos connaissances sont faillibles. N'y a-t-il pas plutôt des savoirs, dont l'histoire nous montre combien leurs modes de validations sont variés? Ce livre entend refuser ce type de réponse contextualiste et relativiste. Il propose de revenir à la réponse de sens commun de Moore, à partir des reformulations contemporaines des raisonnements sceptiques issues de la philosophie analytique de la connaissance. Personne ne peut nous envoyer savoir quelque chose que nous ne pourrions pas savoir. De fait, nous savons, mais notre savoir n'est pas transparent : nous n'avons pas besoin de savoir que nous savons. Pour parvenir à cette réponse, il faut replacer la notion de connaissance, plutôt que celle de croyance justifiée ou rationnelle, au centre de l'épistémologie, et reformuler des questions traditionnelles comme celles de la nature de la perception, du témoignage, et de la connaissance a priori. On peut aussi reprendre le vieux projet d'une enquête sur la nature de la connaissance en général. (shrink)

The doxastic zoo contains many animals: belief, acceptance, belief in, belief that, certainty, conjecture, guess, conviction, denial, disbelief in, disbelief that, judgment, commitment, etc. It also contains belief’s “strange bedfellows”: credences, partial beliefs, tacit beliefs, subdoxastic states, creedal feelings, feelings of knowing, in-between believings, pathological beliefs, phobias, aliefs, delusions, biases, besires. How to order the zoo? I propose to distinguish doxastic attitudes from non-doxastic epistemic attitudes. The criterion is the existence of correctness conditions. Most bedfellows do not have such normative (...) conditions. So they should not be allowed in the Doxastic Club. (shrink)

Résumé Considéré comme l’action individuelle par excellence, le dribble renvoie le plus souvent à l’exercice d’une maîtrise technique que seuls quelques protagonistes d’exceptions sont à même d’exécuter. Cette image purement descriptive, centrée sur le seul pratiquant, n’entretient qu’un lointain rapport avec la réalité de ce qui constitue la raison d’être profonde de cette action motrice. Le dribble, entendue comme un acte qui consiste à conduire un objet, – une balle, un palet –, en alternant des temps de contact et de (...) non contact, est avant tout à envisager dans sa dimension collective. Là est le point aveugle des analyses menées à son propos. Dans cette étude, on considérera le dribble comme un type de conduite motrice porteur d’intentions auxquelles sont attachées des significations de nature essentiellement sociale. Fondamentalement le dribble est relation, c’est-à-dire interaction. Il doit être envisagé sous l’angle de la sémiotricité, autrement dit des significations que les pratiquants lui accordent. Sa fonction est essentiellement d’annoncer les actions futures. À ce titre, il renvoie à une classe de comportements tactiques dont les significations relèvent d’une interprétation en situation sous la dépendance directe des règles du jeu sportif considéré. Loin d’être univoque, le dribble doit être envisagé comme un « signe » qui doit être décodé par les pratiquants en fonction de la grammaire du jeu considéré selon un double axe ; syntagmatique et sémantique. Ce travail à pour objectif de repérer les différentes significations possibles du « signe-dribble », considéré comme un praxème. (shrink)

I raise a dilemma for an epistemology based on the idea that there are hinge propositions or primitive certainties: either such propositions are norms or rules in the 'grammatical' sense, but they cannot regulate our inquiries since they are not genuine propositions obeying truth or evidential standards, or they are epistemic norms, but compete with the classical norms of belief and knowledge. Either there are hinges, but they have nothing to do with epistemology, or hinges are part of our knowledge, (...) and their epistemology is part of ordinary epistemology. (shrink)

Zeki and co-workers recently proposed that perception can best be described as locally distributed, asynchronous processes that each create a kind of microconsciousness, which condense into an experienced percept. The present article is aimed at extending this theory to metacognitive feelings. We present evidence that perceptual fluency—the subjective feeling of ease during perceptual processing—is based on speed of processing at different stages of the perceptual process. Specifically, detection of briefly presented stimuli was influenced by figure-ground contrast, but not by symmetry (...) or the font of the stimuli. Conversely, discrimination of these stimuli was influenced by whether they were symmetric and by the font they were presented in , but not by figure-ground contrast. Both tasks however were related with the subjective experience of fluency . We conclude that subjective fluency is the conscious phenomenal correlate of different processing stages in visual perception. (shrink)

There are mental actions, and a number of epistemic attitudes involve activity. But can there be epistemic agency? I argue that there is a limit to any claim that we can be epistemic agents, which is that the structure of reasons for epistemic attitudes differs fundamentally from the structure of reasons for actions. The main differences are that we cannot act for the wrong reasons although we can believe for the wrong reasons, and that reasons for beliefs are exclusive in (...) a sense in which our reasons for actions are not. Epistemic agency is possible in the weak sense that we can be active, but not in the strong one in which we could have some elbow room for our epistemic reasons in reasoning leading to beliefs and other epistemic states.

Presumption is often discussed in law, less often in epistemology. Is it an attitude? If so where can we locate it within the taxonomy of epistemic attitudes? Is it a kind of belief, a judgment, an assumption or a supposition? Or is it a species of inference? There are two basic models of presumption: judgmental, as a kind of judgment, and legal, taken from the use of presumptions in law. The legal model suggests that presumption is a practical inference, whereas (...) the judgmental model suggests that presumption is an epistemic attitude. I argue that presumption is neither a practical inference nor a merely epistemic attitude: it involves both, within the category of what we may call the inquiring attitudes. (shrink)

This paper argues that emotional inferences about characters in a text are not as specific as previously assumed.

This paper argues that the normative dimension in mental and semantic content is not a categorical feature of content, but an hypothetical one, relative to the features of the interpretation of thoughts and meaning. The views of Robert Brandom are discussed. The thesis defended in this paper is not interpretationist about thought. It implies that the normative dimension of content arises from the real capacity of thinkers and speakers to self ascribe thoughts to themselves and to reach self knowledge of (...) their own thoughts.

Dans cet article, je défends la position évidentialiste à propos des croyances religieuses, à la suite de la fameuse maxime de Clifford et contre l'interprétation pragmatiste de l'éthique des croyances. Je défends, en suivant Shah que le test de transparence est mieux expliqué par l'existence d'une norme de correction de la croyance. Les croyances religieuses, si elles sont des croyances, doivent obéir à cette norme. Si elles n'y obéissent pas, ce ne sont pas des croyances. Et la non croyance est (...) une attitude parfaitement légitime. (shrink)

This chapter analyzes stupidity as a problem for epistemology. Its proper home belongs to virtue epistemology, as a specific epistemic vice, which has to be studied along the lines of both reliabilist virtue epistemology and of responsibilist virtue epistemology. The author distinguishes between two kinds of stupidity: stupidity proper and foolishness. The former is a defect in the competence of an agent, as well as in the performance of judgment, and it is generally studied as a failure of rationality along (...) intellectualist lines. The second is a failure to evaluate properly the nature of the epistemic goal, and is a form of epistemic indifference, which involves an insensitivity to epistemic values and norms. This chapter analyzes their varieties, and suggest that the boundaries between stupidity and foolishness are often less clear than it is suggested by the author’s taxonomy. (shrink)

The diversity of interpretations of Aristotle’s treatment of chance and luck springs from an apparent contradiction between the claims that “chance events are for the sake of something” and that “chance events are not for the sake of their outcome.” Chance seems to entail the denial of an end. Yet Aristotle systematically refers it to what is for the sake of an end. This paper suggests that, in order to give an account of chance, a reference to “per accidens causes” (...) is not sufficient. Chance occurs as a parody of teleology; it is a“for-no-purpose” that looks like a purpose. The notion of “irony” is suggested as a way of accounting for a situation that keeps an ambiguity open. The fact that chance is thought of in relation to teleology does not mean that it is “reappropriated” by teleology. Rather,chance reveals a hiatus that betrays the limitation of a language concerned with substances to account for events. (shrink)

Psycholinguistic investigations of the way readers and speakers perceive gender have shown several biases associated with how gender is linguistically realized in language. Although such variations across languages offer interesting grounds for legitimate cross linguistic comparisons, pertinent characteristics of grammatical systems – especially in terms of their gender asymmetries – have to be clearly identified. In this paper, we present a language index for researchers interested in the effect of grammatical gender on the mental representations of women and men. Our (...) index is based on five main language groups (i.e., grammatical gender languages, languages with a combination of grammatical gender and natural gender, natural gender languages, genderless languages with few traces of grammatical gender and genderless languages) and three sets of specific features (morphology, masculine-male generics and asymmetries). Our index goes beyond existing ones in that it provides specific dimensions relevant to those interested in psychological and sociological impacts of language on the way we perceive women and men. We also offer a critical discussion of any endeavor to classify languages according to grammatical gender. (shrink)

In reply to commentary on our target article, we supply further evidence and hypotheses in the description of ritualized behaviors in humans. Reactions to indirect fitness threats probably activate specialized precaution systems rather than a unified form of danger-avoidance or causal reasoning. Impairment of precaution systems may be present in pathologies other than obsessive-compulsive disorder (OCD), autism in particular. Ritualized behavior is attention-grabbing enough to be culturally transmitted whether or not it is associated with group identity, cohesion, or with any (...) other social aspect of collective ceremonies.

A commonplace in contemporary philosophy is that mental content has normative properties. A number of writers associate this view to the idea that the normativity of content is essentially connected to its social character. I agree with the first thesis, but disagree with the second. The paper examines three kinds of views according to which the norms of thought and content are social: Wittgenstein’s rule following considerations, Davidson’s triangulation argument, and Brandom’s inferential pragmatics, and criticises each. It is argued that (...) there are objective conceptual norms constitutive of mental content, but that these are not essentially social. (shrink)

The author recalls some of the reasons why analytical philosophy has been foreign to contemporary fre philosophical tradition. Presenting some recent work by contemporary fre philosophers influenced by analytic philosophy, He shows that most of them share the view that philosophy is a kind of transcendental inquiry on the nature and limits of language, And that recent trends in analytical philosophy, Such as scientific realism and "naturalised epistemology" are not well represented in france.

In order to study the relationship between genes and diseases, the increasing availability and sharing of phenotypic and genotypic data have been promoted as an imperative within the scientific community. In parallel with data sharing practices by clinicians and researchers, recent initiatives have been observed in which individuals are sharing personal genomic data. The involvement of individuals in such initiatives is facilitated by the increased accessibility of personal genomic data, offered by private test providers along with availability of online networks. (...) Personal webpages and on-line data sharing platforms such as Consent to Research, Free the Data, and Genomes Unzipped are being utilized to host and share genotypes, electronic health records and family history uploaded by individuals. Although personal genomic data sharing initiatives vary in nature, the emphasis on the individuals’ control on their data in order to benefit research and ultimately health care has seen as a key theme across these initiatives. In line with the growing practice of personal genomic data sharing, this paper aims to shed light on the potential challenges surrounding these initiatives. As in the course of these initiatives individuals are solicited to individually balance the risks and benefits of sharing their genomic data, their awareness of the implications of personal genomic data sharing for themselves and their family members is a necessity. Furthermore, given the sensitivity of genomic data and the controversies around their complete de-identifiability, potential privacy risks and harms originating from unintended uses of data have to be taken into consideration.

What is the relationship between logic and reasoning? How do logical norms guide inferential performance? This paper agrees with Gilbert Harman and most of the psychologists that logic is not directly relevant to reasoning. It argues, however, that the mental model theory of logical reasoning allows us to harmonise the basic principles of deductive reasoning and inferential perfomances, and that there is a strong connexion between our inferential norms and actual reasoning, along the lines of Peacocke’s conception of inferential role.

Among recent theories of the nature of self-knowledge, the rationalistic view, according to which self-knowledge is not a cognitive achievement—perceptual or inferential—has been prominent. Upon this kind of view, however, self-knowledge becomes a bit of a mystery. Although the rationalistic conception is defended in this article, it is argued that it has to be supplemented by an account of the transparency of belief: the question whether to believe that P is settled when one asks oneself whether P.

The master argument posits a metaphysical thesis: Diodorus does away with Aristotle’s dunamis understood as a power simultaneously oriented toward being and non-being and proclaims that possibilities that fail to actualize are simply nothing. My contention is that this claim is not a mere application of Diodorus’ contribution to modal logic. Rather, Diodorus creates an ontologico-temporal concept of possibility and impossibility. Diodorus envisions the future as the past that the future will become. Since what will have been can never be (...) the accomplishment of a possibility that did not obtain, and since the future is destined to become past, any futural possibility that doesn’t actualize is neither futural nor even possible.

Une relecture de ce philosophe anglais (1676-1729), à la lumière de ce que disaient de et contre lui ses adversaires théologiens (Clarke, Berkeley), et surtout, de ce qu'il disait de lui-même.

This chapter evaluates Davidson's influence on contemporary philosophy. Although a number of his views on meaning, truth, interpretation, action, and mind have often been rejected within contemporary philosophy, most of most his central themes and basic concepts are still with us and have had a lasting influence. The heritage of Davidson's philosophy lies in the capacity of contemporary philosophers to modify his views and to expand them in new directions.

Many contemporary writers (and Richard Rorty in particular) have attempted to define an "ecumenistic" position, according to which "continental" and "analytic" philosophy should join forces and work together. This has been claimed on behalf of supposed similarities between hermeneutics and interpretation theory. The author tries to show, comparing Gadamer and Davidson on interpretation, that there are, on the contrary, huge differences between these respective approaches.

In ethology, and more generally in the study of animal behavior, observations are _theory-laden_. A review of theories of animal behavior reveals that the animal is a variable _object_, shaped by variable levels of causality. This approach to animal behavior, which differs radically from the way psychology studies human behavior, is a consequence of the difficulty of treating animals as _subjects_ in ethology, where they are most often studied _in the third person_. However, there is a subjectivist tradition in the (...) study of animal behavior, influenced by a phenomenological background. Our aim to promote a _at first person_ approach has led us to propose an etho-phenomenology based on Merleau-Ponty’s phenomenology, Francisco Varela’s enaction theory and constructivist psychology. However, in order to legitimize this approach to animal behavior, we apply it here to behaviors that seem abnormal according to traditional explanatory frameworks, such as actospatiality, tail carrying in mice or expressing ambivalence displayed through color in octopuses. Furthermore, to explore issues such as human-animal communication, the etho-phenomenological perspective is combined with the notion of participatory sense-making, leading us to propose a theory of emotional hybridization.

It is surprisingly difficult to justify private property. Two questions are at stake: (a) a metaphysical and juridical one concerning the nature of property and (b) an ethical one concerning our attitude toward wealth. This issue reached an unprecedented importance during the 12th and 13th centuries as a new moral ideal emerged. This essays analyses the controversy (with emphasis on Bonaventure’s Defense of the Mendicants) by first locating it in relation to the philosophical and theological authorities as well as the (...) Roman law. It argues that the dispute between the defenders of paupertas altissima and their opponents concerns the limit of the law. Gerard of Abbeville and John XXII saw a contradiction in a right to use that would exclude ownership. Yet, what the Franciscans were seeking was use without right. To relate to the world as something that is essentially inappropriable is to seek a form of life (a rule) prior to the law. Centuries after, such a possibility remains to be discovered. (shrink)

The historiography on the concept of race in the post-war sciences has focused predominantly on the UNESCO campaign against scientific racism and on the Anglo-American research community. By way of contrast, this article highlights the history of the concept of race from a thus far unexplored angle: from Swiss research centres and their global interconnections with racial researchers around the world. The article investigates how the acceptance, resonance, and prestige of racial research changed during the post-war years. It analyses what (...) resources could be mobilised that enabled researchers to carry out and continue scientific studies in the field of racial research or even to expand them and link them to new contexts. From this perspective, the article looks at the dynamics, openness, and contingency of the European post-war period, which was less stable, anti-racist, and spiritually renewed than retrospective success stories often suggest. The pronounced internationality of Swiss racial science and its close entanglement with the booming field of human genetics in the early 1950s point to the ambiguities of the period’s political and scientific development. I argue that the impact of post-war anti-racism on science was more limited than is frequently assumed: it did not drain the market for racial knowledge on a continent that clung to imperialism and was still shaped by racist violence. Only from the mid 1950s onwards did a series of unforeseen events and contingent shifts curtail the importance of the race concept in various sectors of the human sciences. (shrink)

This paper examines the “pluralist” conception of truth defended by Crispin Wright, and stresses its difficulties and its dangerous flirtation with relativsm. A solution to these difficulties, which Wright himself contemplates, consists in embracing a functionalist theory of truth, according to which truth is a kind of formal property “realised” differently in various domains. But this view, it is argued, does not get rid of the difficulties of pluralism. It is then argued that we have to accept that truth is (...) one, not many, and a kind of realism about truth, on an epistemological basis. (shrink)
