In his interesting paper, Duca argues that even though people don't apply a logical rule of inference – contraposition- when they try to solve the Wason task, they may be using another kind of formal strategy in terms of probabilistic relations between the antecedent and the consequent. It is suggested that there are two ways of intepreting this task – one logical and apriori, the other hypothetical and data driven. Taking a probabilistic interpretation of the conditional rule for subjects' card selections in the Wason task seems much more justified in this second reading. If this is true, new questions arise: how does a subject recognize which method is contextually appropriate, and what makes a solution contextually rational?

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.

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.

What is a person, and how can a person come to know that she is a person identical to herself over time ? The article defends the view that the sense of being oneself in this sense consists in the ability to consciously affect oneself : in the memory of having affected oneself, joint to the consciousness of being able to affect oneself again. In other words, being a self requires a capacity for metacognition (control and monitoring of one's own internal states). This view is compatible with the hypothesis that the self is a dynamic representation emerging out of a higher level control system, - valuation control - whose articulation with control of plans and perceptual/motor control is discussed in the context of normal and pertrubed agency

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.

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'

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

The abilities to attribute an action to its proper agent and to understand its meaning when it is produced by someone else are basic aspects of human social communication. Several psychiatric syndromes, such as schizophrenia, seem to lead to a dysfunction of the awareness of one’s own action as well as of recognition of actions performed by other. Such syndromes offer a framework for studying the determinants of agency, the ability to correctly attribute actions to their veridical source. Thirty normal subjects and 30 schizophrenic patients with and without hallucinations and/or delusional experiences were required to execute simple finger and wrist movements, without direct visual control of their hand. The image of either their own hand or an alien hand executing the same or a different movement was presented on a TV-screen in real time. The task for the subjects was to discriminate whether the hand presented on the screen was their own or not. Hallucinating and deluded schizophrenic patients were more impaired in discriminating their own hand from the alien one than the non-hallucinating ones, and tended to misattribute the alien hand to themselves. Results are discussed according to a model of action control. A tentative description of the mechanisms leading to action consciousness is proposed.

What I propose is to reconsider the interpretation of Bolzano’s concept of analytic propositions which was offered thirty years ago by Bar-Hillel. The claim of Bar-Hillel was that, in a late addition to his book, The Theory of Science, Bolzano actually had been radically improving his concept of analyticity, thus creating some inconsistencies with the previous, uncorrected version. This allows us to equate the new Bolzanian definition of analytic with what was to be defined, a century later, as logical truth by W. V. Quine. Bar-Hillel’s interpretation has been uncritically accepted by commentators, although the historical issue has been rightly challenged by J. Berg. What I want to show is that, in spite of a surface analogy between Bolzano’s phrasing of the definition of ‘logical analytic’ and Quine’s definition, certain considerations should lead us to call that parallel into question. Attractive as it may be for a Quinian, such a view of Bolzano’s analytic can be shown as incompatible with the leading ideas of his philosophy of logic. Furthermore, there is enough evidence in other sections of the Theory of Science to show that Bolzano’s criterion of analyticity is grounded on purely semantical properties and is part of a general account of logical properties in terms of the mapping of propositions to corresponding models.

This book deals with the experience of externality, i.e. an experience, common in schizophrenia, present both in verbal hallucination and in thought insertion. The view defended is that thought insertion is a case of failed agency, experienced by the agent at the personal level as an intelligible thought with which she cannot identify. Such a case in which sense of agency and sense of subjectivity come apart reveals the existence of two dimensions in self-consciousness. Several difficulties of the solution offered are discussed, in connection with the causal-explanatory role of the phenomenological features of the experience and with the view that thinking is a variety of acting.

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.

Granted that a given species is able to entertain beliefs and desires, i.e. to have (epistemic and motivational) internal states with semantically evaluable contents, one can raise the question of whether the species under investigation is, in addition, able to represent properties and events that are not only perceptual or physical, but mental, and use the latter to guide their actions, not only as reliable cues for achieving some output, but as mental cues (that is: whether it can 'read minds'). The main aim of this article is to suggest that mindreading depends on two prior capacities : exercising simulation, as when one actively disengages from the present environment to imagine a counterfactual situation, and exploiting simulation, which implies that an imaginary situation is relocated within the real world. It is claimed that although apes have the first capacity, they don't have the second one, and therefore do not have access to mental attribution
