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.

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

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

_Questions of Form _was first published in 1989. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. In _Questions on Form_, Joelle Proust traces the concept of the analytic proposition from Kant's development of the notion down to its place in the work of Rudolf Carnap, a founder of logical empiricism and a key figure in contemporary analytic philosophy. Using a method known in France as _topique comparative_,she provides a rigorous exposition of analyticity, situating it within four major philosophical systems—those of Kant, Bolzano, Frege, and Carnap—and clearly delineating its development from one system to the next. Proust takes as her point of departure Kant's distinction between analytic and synthetic judgments. Though she makes clear that Kant drew on Locke, Hume, and Leibniz, she argues that his notion of analyticity was innovative, not simply an elaboration of something already found in their work. She shows that the analytic proposition unexpectedly (given its modest status in Kant) came to play an important part in efforts to convert problems considered "transcendental" into questions of belonging to formal logic. Ultimately, her comparison of their systems reveals that the concept of the analytic, however specific its rile in each, remains linked to a foundationalist strategy—in effect, to the transcendentalist questions Kant used when he reinterpreted the findings of his empiricist predecessors. 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.
