RésuméCet article s'attaque au problème de l'indétermination fonctionnelle dans l'un de ses aspects, dit «intensif», celui où un indicateur interne peut répondre soit au stimulus proximal occasioné sur les récepteurs sensoriels par une propriété extérieure, soit au stimulus correspondant – cette propriété elle‐même. A près avoir montré pourquoi la solution de Dretske ne permet pas de rendre compte principiellement de ce qui distingue les deux types de fonction représentationnelle d'un indicateur, cet article procède à une analyse de ce qui distingue (...) un descripteur de stimulus proximal d'un descripteur de stimulus distal. Deux critères sont utilisés: 1) le graphe des fonctions de traitement de l'information d'entré est différent s'il s'agit d'un stimulus proximal‐cova‐recalibration de l'information par le recours à une modalité sensorielle dominante sont mises en œuvre quand le système est capable de former des descripteurs distaux. La capacité de rectifier l'information proximale pour maintenir la covariation avec la source distale de l'information constitue ainsi une condition néessaire et suffisante de l'existence d'une représentation distale contrôlant le comportement. Plusieurs conséquences de cette définition de la distalité sont examinées du point de vue de l'approche externaliste de l'intentionnalité. (shrink)

La connaissance de soi suppose que l'on puisse former des pensées vraies de la forme 'je Y que P', où 'Y' fait référence à une attitude propositionnelle, 'P' à son contenu, et 'je' au penseur de cette pensée. La question qui se pose est de savoir, ce qui, dans le contenu mental occurrent [P], justifie l'auto-attribution de cette pensée. Ce problème dit de la transition soulève trois difficultés ; celle de la préservation du contenu intentionnel entre la pensée de premier (...) et de second ordre ; celle de la reconnaissance de l'attitude ayant ce contenu intentionnel pour objet, et enfin la reconnaissance que ce qui est pensé l'est par le sujet qui pense. Le présent article se propose de montrer que la troisième difficulté résiste à une approche fondée sur l'expérience ou sur la signification cognitive de [P], et avance l'idée que la notion d'action mentale permet d'éclairer les conditions d'identité du penseur de [P] et du sujet de l'auto-attribution de l'attitude propositionnelle 'Y que P'.Self-knowledge requires the capacity to think true thoughts of the form 'I Y that P', where 'Y' refers to a propositional attitude, 'P' to a propositional content, and 'I' to the thinker of the thought of content P. The question that this requirement raises is to know what, in the occurrent mental content [P] , justifies the self-attribution of this thought. This problem, called the transition problem, includes three difficulties : how is intentional content stable across first- and second-order thoughts ? How is the attitude with this intentional content identified by the thinker ? And how is the thinker of the second-order thought able to claim truly that he himself is the thinker of the first-order thought ? The present paper's aim is to show that the third difficulty cannot be solved through an examination of the experience of having [P] or on the basis of the cognitive significance of P, and suggests that an analysis of mental actions in which propositional attitudes play a causal and feedback role give a better grasp on the conditions of identity of the thinker of [P] with the thinker of the propositional attitude 'Y that P'.

Dans son compte-rendu de mon livre, Les Animaux Pensent-ils?, Machery objecte que l'évolution n'étant ni hiérarchique ni linéaire, il n'et pas justifié de proposer une analyse hiérarchique des représentations. Je réponds à cette objection, en montrant qu'on peut en effet distinguer des types de représentation par leurs propriétés sémantiques et computationnelles. On peut reconnaître le caractère anagénétique du développement de la cognition sans pour autant légitimer une conception hiérarchique et continuiste de l'évolution des espèces.

A propos de 'Evolution et Rationalité' de Ronald de Sousa (2004).

Dans la psychose, les données cliniques montrent que dès l'apparition des premiers troubles aigus, une difficulté caractéristique se manifeste au niveau de l'attribution de la responsabilité causale des actions. Les patients se sentent poussés à agir par les autres tout en ayant aussi le sentiment de contrôler l'action d'autrui. Cette difficulté va souvent de pair chez les schizophrènes avec une modification du sentiment d'identité personnelle. Parmi les symptômes de l'autisme, on trouve des difficultés de contrôle de l'action, une réduction des (...) centres d'intérêts, des stéréotypies comportementales et une difficulté à comprendre les événements d'ordre mental. Des résultats expérimentaux récents permettent d'orienter la réflexion théorique sur l'origine fonctionnelle commune de ces perturbations. Ils indiquent l'importance du suivi de l'action dans l'acquisition par l'enfant d'une " théorie de l'esprit ", c'est-à-dire des connaissances nécessaires à l'interprétation de ses propres états mentaux et de ceux d'autrui. Dans le cas de l'adulte, un mauvais suivi de l'action pourrait porter atteinte à la capacité de reconnaître ses propres intentions d'agir, et modifier ainsi le sens de sa propre identité. Subjectivité et conscience d'agir rassemble des travaux de clinique psychiatrique (Henri Grivois), de psychologie du développement (James Russell), de neuroscience cognitive (Marc Jeannerod, Pierre Fourneret) et de philosophie de l'esprit (John Campbell, Pascal Engel, Elisabeth Pacherie, Joëlle Proust). Le point commun est d'élucider le rôle qui revient aux fonctions exécutives dans la compréhension de soi-même et d'autrui. L'ouvrage s'adresse aux étudiants, aux enseignants et aux chercheurs en psychologie, en neuroscience et en philosophie, mais aussi aux psychiatres et aux cliniciens, ainsi qu'à tous ceux qui s'intéressent aux progrès de la psychopathologie cognitive.

This articles examines three ways in which the connection between semantic and pragmatic representations of a single action can be tightened up in order to remedy the puzzle of deviant causation. A first move consists in making the feedback process, i.e. the dynamics of the relationship between both representational components, a central element in the definition of an action. A second step brings in the action-effect principle, emphasizing the teleological relation of each pragmatic representation type with its external effects. A (...) final step consists in elucidating the constitutive character of demonstrative reference for the contents of working memory states. (shrink)

Cet article résume l'ouvrage paru en 2005 et répond aux objections de Stéphane Chauvier, Daniel Laurier et Pierre Livet dans le cadre d'une disputatio organisée par la revue Philosophiques.

Le déterminisme implique que le libre arbitre n’existe pas, que nous ne pouvons pas faire autrement ; réciproquement, avoir la possibilité de faire autrement implique que le déterminisme ne s’applique pas à l’instant, s’il existe, où on l’exerce. Cependant, la question de la responsabilité rend difficile d’accepter que les agents ne puissent pas faire autrement et motive fortement à rendre compatibles déterminisme et libre arbitre ou à soutenir, dans une veine « incompatibiliste », que le cerveau humain n’est pas soumis (...) à la loi du déterminisme. Le libertarianisme, c’est-à-dire l’idée que, chez l’agent humain, il existe des exceptions au déterminisme causal lors de l’activité cérébrale, n’est pas défendable à la lumière des découvertes récentes sur la cognition humaine. Selon le compatibilisme, un agent n’ayant pas la possibilité de faire autrement jouit encore de son Libre Arbitre. La théorie de Harry Frankfurt d’une volonté à plusieurs niveaux est étudiée de manière critique. On présente la preuve neuroscientifique d’un modèle de volonté en cascade, dans l’esprit de Frankfurt. Ce modèle permet l’émergence d’une forme de comptabilisme dans lequel l’agent peut plus ou moins contrôler ce qu’elle fait, dépendre plus ou moins de son environnement et dispose donc plus ou moins de son libre arbitre.

Cet article recense et discute le récent livre de Joëlle Proust, Les animaux pensent-ils ?. Proust s'appuie sur les récents développements en psychologie animale et en éthologie pour fournir des réponses nouvelles à des questions philosophiques traditionnelles, comme « les animaux pensent-ils » ou « les animaux parlent-ils ? ». Ce livre est à recommander aussi bien aux étudiants qu'aux chercheurs confirmés. Toutefois, malgré son intérêt, je souligne une limite critique de l'approche de Proust : plusieurs (...) arguments souffrent du fait que les positions que Joëlle Proust défend sont insuffisamment inspirées par une perspective évolutionniste et écologique. Je mets en avant les mérites d'une approche évolutionniste et écologique de la cognition animale. (shrink)

A prominent but poorly understood domain of human agency is mental action, i.e., thecapacity for reaching specific desirable mental statesthrough an appropriate monitoring of one's own mentalprocesses. The present paper aims to define mentalacts, and to defend their explanatory role againsttwo objections. One is Gilbert Ryle's contention thatpostulating mental acts leads to an infinite regress.The other is a different although related difficulty,here called the access puzzle: How can the mindalready know how to act in order to reach somepredefined result? A (...) crucial element in the solutionof these puzzles consists in making explicit thecontingency between mental acts and mentaloperations, parallel to the contingency betweenphysical acts and bodily movements. The paper finallydiscusses the kind of reflexivity at stake in mentalacts; it is shown that the capacity to refer tooneself is not a necessary condition of the successfulexecution of mental acts.

Hence, this book's provocative claim: today's so-called logical empiricism owes much more to Kant's notion of science than to Hume's.

Granting that various mental events might form the antecedents of an action, what is the mental event that is the proximate cause of action? The present article reconsiders the methodology for addressing this question: Intention and its varieties cannot be properly analyzed if one ignores the evolutionary constraints that have shaped action itself, such as the trade-off between efficient timing and resources available, for a given stake. On the present proposal, three types of action, impulsive, routine and strategic, are designed (...) to satisfy the trade-off above when achieving goals of each type. While actions of the first two types depend on non-conceptual appraisals of a given intensity and valence, strategic intentions have a propositional format and guide action within longer-term executive frameworks involving prospective memory.

Given disagreement about the architecture of the mind, the nature of self‐knowledge, and its epistemology, the question of how to understand the function and the scope of metacognition – the control of one’s cognition – is still a matter of hot debate. A dominant view, the self‐ascriptive view, has been that metacognition necessarily requires representing one’s own mental states as mental states, and, therefore, necessarily involves an ability to read one’s mind. The main claims of this view are articulated, and (...) the difficulties that they raise are discussed. An alternative view of metacognition, the ‘self‐evaluative view’, is then examined. It is argued that this view provides an account of metacognition that is both empirically and conceptually more adequate than the self‐ascriptive model. Particular attention is given to the problem of transferring self‐evaluative judgments to the case of others. (shrink)

This paper discusses the content of agency awareness. It contrast three elements in content: what the goal is, how it is to be reached, and who is having the goal/performing the action ? Marc Jeannerod's claim that goal representations are self-other neutral is discussed. If goal representations are essentially sharable, then we do not understand other people by projecting a piece of internal knowledge on to them, as often assumed. The problem which our brain has to solve is the converse (...) problem : determining who the agent is, once a goal is identified. This view has interesting consequences on the theory of mentalization. One can plausibly speculate that observing action, with an additional simulatory component for action memory, form major building blocks in understanding other minds. Metarepresenting, in this perspective, would depend on additional executive capacities for maintaining distinct the inferences from diverse simulated contexts of action. (shrink)

The project of understanding rationality in non-human animals faces a number of conceptual and methodological difficulties. The present chapter defends the view that it is counterproductive to rely on the human folk psychological idiom in animal cognition studies. Instead, it approaches the subject on the basis of dynamic- evolutionary considerations. Concepts from control theory can be used to frame the problem in the most general terms. The specific selective pressures exerted on agents endowed with information-processing capacities are analysed. It is (...) hypothesized that metacognition offers an evolutionary stable response to the various demands of the internal and external flows of information in a competitive environment. Metacognition provides a form of process-reflexivity that can, but does not have to be redeployed through metarepresentations. Finally the claim that rationality so conceived involves normativity is discussed. (shrink)

Against the view that metacognition is a capacity that parallels theory of mind, it is argued that metacognition need involve neither metarepresentation nor semantic forms of reflexivity, but only process-reflexivity, through which a task-specific system monitors its own internal feedback by using quantitative cues. Metacognitive activities, however, may be redescribed in metarepresentational, mentalistic terms in species endowed with a theory of mind.

Experience of agency in patients with schizophrenia involves an interesting dissociation; these patients demonstrate that one can have a thought or perform an action consciously without being conscious of thinking or acting as the motivated agent, author of that thought or of that action. This chapter examines several interesting accounts of this dissociation, and aims at showing how they can be generalized to thought insertion phenomena. It is argued that control theory allows such a generalization; three different comparators need to (...) be distinguished: the sense of subjectivity relies on a comparator in which motivation and emotion play a structuring role. The sense of agency emerges in a system that delivers a rough categorization of self-generated – versus other- generated – actions and mental activities. A third system specializes in the social evaluation of the effects of an action, intention or other thought process, given certain goals in self or in others. (shrink)

Against the prior view that primate communication is based only on signal decoding, comparative evidence suggests that primates are able, no less than humans, to intentionally perform or understand impulsive or habitual communicational actions with a structured evaluative nonconceptual content. These signals convey an affordance-sensing that immediately motivates conspecifics to act. Although humans have access to a strategic form of propositional communication adapted to teaching and persuasion, they share with nonhuman primates the capacity to communicate in impulsive or habitual ways. (...) They are also similarly able to monitor fluency, informativeness and relevance of messages or signals through nonconceptual cues. (shrink)

This paper defends the view that knowledge about one's own intentions can be gained in part through perception, although not through introspection. The various kinds of misperception of one's intentions are discussed. The latter distinction is applied to the analysis of schizophrenic patients' delusion of control.

Controlling one's mental agency encompasses two forms of metacognitive operations, self-probing and post-evaluating. Metacognition so defined might seem to fuel an internalist view of epistemic norms, where rational feelings are available to instruct a thinker of what she can do, and allow her to be responsible for her mental agency. Such a view, however, ignores the dynamics of the mind–world interactions that calibrate the epistemic sentiments as reliable indicators of epistemic norms. A 'brain in the lab' thought experiment suggests that (...) an internalist view of epistemic feelings is unable to account for the contrast between norm-tracking, educated sentiments, and illusory feelings.

An area in the theory of action that has received little attention is how mental agency and world-directed agency interact. The purpose of the present contribution is to clarify the rational conditions of such interaction, through an analysis of the central case of acceptance. There are several problems with the literature about acceptance. First, it remains unclear how a context of acceptance is to be construed. Second, the possibility of conjoining, in acceptance, an epistemic component, which is essentially mind-to-world, and (...) a utility component, which requires a world-to-mind direction of fit, is merely posited rather than derived from the rational structure of acceptance. Finally, the norm of acceptance is generally seen as related to truth, which turns out to be inapplicable in a number of cases. We will argue, first, that the specific context-dependence of acceptances is derived from their being mental actions, each embedded in a complex hierarchy of acceptances composing, together, a planning sequence. Second, that acceptances come in several varieties, corresponding to the specific epistemic norm(s) that constitute them. The selection of a particular norm for accepting answers to considerations of utility – to the association of an epistemic goal with an encompassing world-directed action. Once a type of acceptance is selected, however, the epistemic norm constitutive for that acceptance strictly applies. Third, we argue that context-dependence superimposes a decision criterion on the output of the initial epistemic acceptance. Strategic acceptance is regulated by instrumental norms of expected utility, which may rationally lead an agent to screen off her initial epistemic acceptance. (shrink)
