Trying to understand better the role played by epistemic artifacts in our quest for reliable knowledge, it is interesting to compare their contribution with the one made by the epistemic organs or systems with which we are naturally endowed. This comparative approach may yield the further benefit of an improved understanding of the nature and epistemic functions of our natural epistemic equipment. In this paper, I shall concern myself with comparing the role of a family of instruments, microscopes, with that of visual systems and with assessing the similarities and dissimilarities in accounts of their epistemic contributions

Cet article examine un problème particulier posé par une approche naturaliste et représentationnaliste de la perception: lui est-il ou non possible de rendre compte d'une caractéristique que Husserl considérait comme constitutive de la perception, à savoir le fait que l'objet dans la perception est comme donné en personne (leibhaftig). La première section donne un bref aperçu des motivations qui sont à l'origine de l'intérêt actuellement suscité dans les sciences cognitives par l'intentionnalité perceptive. La deuxième section aborde le problème de la Leibhaftigkeit de l'objet dans la perception et examine les raisons pour lesquelles celle-ci peut paraître constituer une difficulté pour une approche représentationnelle de la perception. La dernière section examine les moyens dont une telle approche dispose pour résoudre ce problème. This paper examines the problem whether a naturalistic and representational approach to perception can account for a feature that Husserl considers as a fundamental caracteristic of perception, namely the fact that the object in perception appears as if given in person (leibhaftig). The first section briefly sketches the reasons why perceptual intentionality is presently the focus of a lot of attention in cognitive science. The second section is concerned with the problem of the Leibhaftigkeit of the object in perception and with the reasons why this may constitute a difficulty for a representational approach to perception.The last section considers the moves available to such an approach in order to solve the problem

In this paper, we evaluate the proposal that a central function of commitments within joint action is to reduce various kinds of uncertainty, and that this accounts for the prevalence of commitments in joint action. While this idea is prima facie attractive, we argue that it faces two serious problems. First, commitments can only reduce uncertainty if they are credible, and accounting for the credibility of commitments proves not to be straightforward. Second, there are many other ways in which uncertainty is commonly reduced within joint actions, which raises the possibility that commitments may be superfluous. Nevertheless, we argue that the existence of these alternative uncertainty reduction processes does not make commitments superfluous after all but, rather, helps to explain how commitments may contribute in various ways to uncertainty reduction.

My main thesis is this paper is that, although Dretske's distinction between simple perception and cognitive perception constitutes an important milestone in contemporary theorizing on perception, it remains too coarse to account for a number of phenomena that do not seem to fall squarely on either side of the divide. I argue that what is needed in order to give a more accurate account of perceptual phenomena is not a twofold distinction of the kind advocated by Dretske but a threefold distinction allowing for an intermediate level of perceptual content that is structured and yet non-conceptual. In the first section, I discuss Dretske's distinction between sensory perception and cognitive perception as well as a number of attendant notions. In section 2, two sets of phenomena that seem neither to constitute instances of sensory perception nor instances of cognitive perception as defined by Dretske are presented. I argue that they are evidence in favor of the existence of an intermediate level of perception. In section 3, I defend the view that this intermediate level of content is a level of structured non-conceptual perceptual content and I attempt to provide criteria for distinguishing among the three levels of content.

Holophobia can be defined as the 'neurotic' fear that semantic holism, if not instantly extirpated by the most radical means, might be a deadly threat to intentional realism. I contend that Fodor exaggerates the threat that meaning holism poses to intentional realism and to a viable account of narrow content in terms of conceptual roles. He particular, he overestimates the relevance for intentional psychology of Quine's demonstration that a substantial analytic/synthetic distinction is out of reach.I argue that all that is needed to defeat the more radical varieties of meaning holism is a weaker distinction than the full-blown and allegedly inexistent analytic/synthetic distinction - namely, a distinction between what is treated as if it were analytic by a cognitive system and what is treated as if it were synthetic

La question du statut ontologique des attitudes propositionnelles et, corrélativement, celle de l'efficacité causale des contenus mentaux sont parmi les principaux problèmes actuellement débattus en philosophie de la psychologie. La théorie des systèmes intentionnels de Dennett, tout en accordant une valeur prédictive aux attributions d'attitudes propositionnelles, refuse aux croyances et désirs droit d'entrée dans une ontologie scientifique. Le but de cet article est de proposer une analyse critique de cette théorie et des arguments darwiniens qui la sous-tendent. The question of the ontologicul status of propositional attitudes, and, closely related to it, the question of the causal efficacy of mental contents are among the main issues currently discussed in the philosophy of psychology. Dennett's theory of intentional systems, while acknowledging the predictive value of intentional attributions, denies beliefs and desires a full ontological status. This paper proposes a critical analysis of Dennett's theory and of the Darwinian arguments he appeals to in support of it.

Two main approaches can be discerned in the literature on agentive self-awareness: a top-down approach, according to which agentive self-awareness is fundamentally holistic in nature and involves the operations of a central-systems narrator, and a bottom-up approach that sees agentive self-awareness as produced by lowlevel processes grounded in the very machinery responsible for motor production and control. Neither approach is entirely satisfactory if taken in isolation; however, the question of whether their combination would yield a full account of agentive self-awareness remains very much open. In this paper, I contrast two disorders affecting the control of voluntary action: the anarchic hand syndrome and utilization behavior. Although in both conditions patients fail to inhibit actions that are elicited by objects in the environment but inappropriate with respect to the wider context, these actions are experienced in radically different ways by the two groups of patients. I discuss how top-down and bottom-up processes involved in the generation of agentive self-awareness would have to be related in order to account for these differences.

We argue that thought insertion primarily involves a disruption of the sense of ownership for thoughts and that the lack of a sense of agency is but a consequence of this disruption. We defend the hypothesis that this disruption of the sense of ownership stems from a fail- ure in the online integration of the contextual information related to a thought, in partic- ular contextual information concerning the different causal factors that may be implicated in their production. Loss of unity of consciousness, manifested by incoherent subjective experiences is a general phenomenal characteristic of schizophrenia. This loss of coherence has been hypothesized to reflect a generalized deficit of contextual information integration not conveyed by, but related to, a target event. This deficit is manifested across many cog- nitive domains. We argue that it is also manifested in the process of thinking itself, result- ing in causally decontextualized thoughts that are experienced as inserted thoughts.

In this paper I argue that, to make intentional actions fully intelligible, we need to posit representations of action the content of which is nonconceptual. I further argue that an analysis of the properties of these nonconceptual representations, and of their relation- ships to action representations at higher levels, sheds light on the limits of intentional control. On the one hand, the capacity to form nonconceptual representations of goal-directed movements underscores the capacity to acquire executable concepts of these movements, thus allowing them to come under intentional control. On the other hand, the degree of autonomy these nonconceptual representations enjoy, and the specific temporal constraints stemming from their role in motor control, set limits on intentional control over action execution.

It is widely assumed, both in philosophy and in the cognitive sciences, that perception essentially involves a relative or egocentric frame of reference. Levinson has explicitly challenged this assumption, arguing instead in favour of the 'neo-Whorfian' hypothesis that the frame of reference dominant in a given language infiltrates spatial representations in non-linguistic, and in particular perceptual, modalities. Our aim in this paper is to assess Levinson's neo-Whorfian hypothesis at the philosophical level and to explore the further possibility that perception may not just use frames of reference other than the relative one but may also, in some cases at least, be perspective-free

The purpose of this paper is to explore the question whether and in what sense emotions might be said to provide reasons for actions or to rationalize them. This requires that one have a picture of the causal structure of actions that is sufficiently detailed for one to see how emotions can impinge on the proc-ess of action production. I present a two-tiered model of action explanation and try to exploit this model in a tentative account of the modes of in-volvement of emotions in the explanation of action. In particular, I examine in what sense emotions can be said not just to explain actions, but also to rationalize them
