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)

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.

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)

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.

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'.

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.

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

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.

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.

Does metacognition--the capacity to self-evaluate one's cognitive performance--derive from a mindreading capacity, or does it rely on informational processes? Joëlle Proust draws on psychology and neuroscience to defend the second claim. She argues that metacognition need not involve metarepresentations, and is essentially related to mental agency.

This book chapter aims at exploring how intentional a piece of behavior should be to count as an action, and how a minimal view on action, not requiring a richly intentional causation, may still qualify such a behavior as voluntary.

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.

Peter Carruthers correctly claims that metacognition in humans may involve self-directed interpretations (i.e., may use the conceptual interpretative resources of mindreading). He fails to show, however, that metacognition cannot rely exclusively on subjective experience. Focusing on self-directed mindreading can only bypass evolutionary considerations and obscure important functional differences.

This chapter examines whether, and in what sense, one can speak of agentive mental events. An adequate characterization of mental acts should respond to three main worries. First, mental acts cannot have pre-specified goal contents. For example, one cannot prespecify the content of a judgment or of a deliberation. Second, mental acts seem to depend crucially on receptive attitudes. Third, it does not seem that intentions play any role in mental actions. Given these three constraints, mental and bodily actions appear (...) to have a significantly different structure. A careful analysis of the role of normative requirements, distinguishing them from instrumental reasons, allows the distinction between mental and bodily forms of action to be clarified. Two kinds of motives must be present for a mental act to develop. The first kind is instrumental: a mental act is performed because of some basic informational need, such as the need to "remember the name of that play". The second kind is normative: given the specific type of mental action performed, there is a specific epistemic norm relevant to that act. These two motives actually correspond to different phases of a single mental act. The first motivates the mental act, i.e. makes salient the corresponding goal. The second offers an evaluation of the feasibility of the act, on the basis of its constitutive normative requirement. Conceived in this way, a characterization of mental acts avoids the three difficulties mentioned above. The possibility of pre-specifying the outcome of epistemic mental acts is blocked by the fact that such acts are constituted by strict normative requirements. That mental acts include receptive features is shown to be a necessary architectural constraint for mental agents to be sensitive to epistemic requirements. Finally, the phenomenology of intending is shown to be absent in most mental acts; the motivational structure of mental acts is, rather, associated with error- signals and self-directed doubtings. Mental acts need to be recognized as a natural kind of action meant to normatively control and enhance cognitive efficiency according to current processing needs. (shrink)

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)

This paper examines the response offered by Robert Gordon to the question how an interpreter can reach the correct content of others'psychological states. It exposes the main problems raised by Gordon's proposal, and provides a tentative solution that emphasizes the structuring role of counterfactual reasoning in embedding simulations and deriving facts that are holding across them.

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)

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.

Phil Gerrans comments on Proust's paper entitled 'Thinking of oneself as the same' raise two points; one has to do with the value of sceptical arguments about self-knowledge, the other with what a self can know of him/herself. These two comments are discussed. It is shown first that metacognition operates on content as well as on vehicles, which leaves every replica with her own numerical identity. Second, the homuncular fallacy is discussed as part of a response to the second (...) point. (shrink)

Metacognition is often defined as thinking about thinking. It is exemplified in all the activities through which one tries to predict and evaluate one’s own mental dispositions, states and properties for their cognitive adequacy. This article discusses the view that metacognition has metarepresentational structure. Properties such as causal contiguity, epistemic transparency and procedural reflexivity are present in metacognition but missing in metarepresentation, while open-ended recursivity and inferential promiscuity only occur in metarepresentation. It is concluded that, although metarepresentations can redescribe metacognitive (...) contents, metacognition and metarepresentation are functionally distinct. (shrink)

This chapter aims to relate two fields of research that have been rarely – if ever – associated, namely embodied communication and metacognition. Exploring this relationship offers a new perspective for understanding the relationship between self-knowledge and mindreading. "Embodied communication" refers to the process of conveying information to one or several interlocutors through speech and associated bodily gestures, or through gestures only. It is prima facie plausible that embodied communication crucially involves metacognitive interventions. Let the term ‘conversational metacognition’ refer to (...) the set of abilities that allow an embodied speaker to make available to others and to receive from them specific markers concerning his/her "conversing adequacy". The hypothesis explored is that embodied communication in humans involve metacognitive gestures. Examples are offered from manual gesturing and from orofacial expressions. A final discussion examines the respective roles of altruistic and Machiavellian pressures in conversational metacognition. (shrink)

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.
