Because of the difficulty posed by the contrast between the search for truth and truth itself, Michael Polanyi believes that we must alter the foundation of epistemology to include as essential to the very nature of mind, the kind of groping that constitutes the recognition of a problem. This collection of essays, assembled by Marjorie Grene, exemplifies the development of Polanyi's theory of knowledge which was first presented in Science, Faith, and Society and later systematized in Personal Knowledge. Polanyi believes (...) that the dilemma of the modern mind arises from the peculiar relation between the positivist claim for total objectivity in scientific knowledge and the unprecedented moral dynamism characterizing the social and political aspirations of the last century. The first part of Knowing and Being deals with this theme. Part two develops Polanyi's idea that centralization is incompatible with the life of science as well as his views on the role of tradition and authority in science. The essays on tacit knowing in Part Three proceed directly from his preoccupation with the nature of scientific discovery and reveal a pervasive substructure of all intelligent behavior. Polanyi believes that all knowing involves movement from internal clues to external evidence. Therefore, to explain the process of knowing, we must develop a theory of the nature of living things in general, including an account of that aspect of living things we call "mind." Part Four elaborates upon this theme. (shrink)

We are even less aware of our internal organs and the physiological processes that keep us alive. In this fascinating work, Drew Leder examines all the ways in which the body is absent—forgotten, alien, uncontrollable, obscured.

Madness and Modernism provides a phenomenological study of schizophrenic disorders, criticizing some standard conceptions of these disorders. Sass argues that many aspects of this group of disorders can actually involve more sophisticated (albeit dysfunctional) forms of mind and experience.

This paper concerns how motor actions are neurally represented and coded. Action planning and motor preparation can be studied using a specific type of representational activity, motor imagery. A close functional equivalence between motor imagery and motor preparation is suggested by the positive effects of imagining movements on motor learning, the similarity between the neural structures involved, and the similar physiological correlates observed in both imaging and preparing. The content of motor representations can be inferred from motor images at a (...) macroscopic level, based on global aspects of the action and the motor rules and constraints which predict the spatial path and kinematics of movements. A more microscopic neural account calls for a representation of object-oriented action. Object attributes are processed in different neural pathways depending on the kind of task the subject is performing. During object-oriented action, a pragmatic representation is activated in which object affordances are transformed into specific motor schemas. Animal as well as human clinical data implicate the posterior parietal and premotor cortical areas in schema instantiation. A mechanism is proposed that is able to encode the desired goal of the action and is applicable to different levels of representational organization. (shrink)

Memory. There may be nothing more important to human beings than our ability to enshrine experience and recall it. While philosophers and poets have elevated memory to an almost mystical level, psychologists have struggled to demystify it. Now, according to Daniel Schacter, one of the most distinguished memory researchers, the mysteries of memory are finally yielding to dramatic, even revolutionary, scientific breakthroughs. Schacter explains how and why it may change our understanding of everything from false memory to Alzheimer's disease, from (...) recovered memory to amnesia with fascinating firsthand accounts of patients with striking—and sometimes bizarre—amnesias resulting from brain injury or psychological trauma.

How can we better understand and treat those suffering from schizophrenia and manic-depressive illnesses? This important new book takes us into the world of those suffering from such disorders. Using self descriptions, its emphasis is not on how mental health professionals view sufferers, but on how the patients themselves experience their disorder. A new volume in the International Perspectives in Philosophy and Psychiatry series, this book will be of great interest to all those working with sufferers from such disorders - (...) helping them to better understand their mental lives, and providing important insights into how best to treat them.

This paper offers a framework for consciousness of internal reality. Recent PET experiments are reviewed, showing partial overlap of cortical activation during self-produced actions and actions observed from other people. This overlap suggests that representations for actions may be shared by several individuals, a situation which creates a potential problem for correctly attributing an action to its agent. The neural conditions for correct agency judgments are thus assigned a key role in self/other distinction and self-consciousness. A series of behavioral experiments (...) that demonstrate, in normal subjects, the poor monitoring of action-related signals and the difficulty in recognizing self-produced actions are described. In patients presenting delusions, this difficulty dramatically increases and actions become systematically misattributed. These results point to schizophrenia and related disorders as a paradigmatic alteration of a ''Who?'' system for self-consciousness. (shrink)

My initial scope will be limited: starting from a neurobiological standpoint, I will analyse how actions are possibly represented and understood. The main aim of my arguments will be to show that, far from being exclusively dependent upon mentalistic/linguistic abilities, the capacity for understanding others as intentional agents is deeply grounded in the relational nature of action. Action is relational, and the relation holds both between the agent and the object target of the action , as between the agent of (...) the action and his/her observer . Agency constitutes a key issue for the understanding of intersubjectivity and for explaining how individuals can interpret their social world. This account of intersubjectivity, founded on the empirical findings of neuroscientific investigation, will be discussed and put in relation with a classical tenet of phenomenology: empathy. I will provide an 'enlarged' account of empathy that will be defined by means of a new conceptual tool: the shared manifold of intersubjectivity. (shrink)

Suitable for students and scholars, this title challenges the assumption that skepticism, rather than established belief, lies at the heart of scientific discovery.

These lectures are the first extensive application of Husserl's newly developed genetic phenomenology to perceptual experience & to the way in which it is connected to judgments & cognition. Students of phenomenology will find this work indispensable.

This paper clarifies the notion of "contact with reality" by investigating one way in which lack of such contact can be expressed: the interrogative attitude. The case of a socially withdrawn, seventeen-year-old schoolboy is examined. Paul C. had long been overly logical and precise in his style of thinking. An acute disturbance began with mental fatigue along with apparent obsessive symptoms (e.g., extreme monitoring of his own actions) to the point that simple, everyday actions became very time-consuming; he also developed (...) a tendency to ask endless questions even about trivial phenomena. However, unlike those of the true obsessive, Paul's monitoring, doubting, and querying seemed to lack any emotional or personal element; he was not anxious but, rather, apathetic. Also, Paul lacked real curiosity: To him, everything had the same level of importance, and his attention was not directed by any precise or personal goal. This paper argues that Paul's interrogative attitude was actually a form of autistic-schizophrenic thinking characterized by "pragmatic weakening" and a loss of vital contact with reality, which are consequences of a weakening of the "élan vital" with its "vital propulsion toward the future." Such patients retain their intellectual powers but do not use these powers in accord with the requirements of reality. The interrogative attitude can be seen as a compensation mechanism—a way to maintain some minimal contact with the world. The paper ends with psychotherapeutic recommendations.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 8.4 (2001) 323-326 [Access article in PDF] The Tacit Dimension Thomas Fuchs Thirty years after its appearance, Blankenburg's "Psychopathology of common sense" has not lost its relevance. In my commentary I will try to illustrate the fruitfulness of his approach by pointing to some connections with the phenomenology of the body as well as with recent memory and infant research.As Blankenburg himself indicates, the notion (...) of common sense developed by a shift of meaning from the classical sensus communis and thus has its original basis in the sensual-bodily experience. By the koinè aísthesis, Aristoteles meant a central sense organ integrating all single modalities of sensation (which he localized in the heart). In German physiology and psychiatry of the nineteenth century, the sensus communis was still translated as "Gemeingefühl" ("common feeling") or "cenesthesia" (Fuchs 1995). This term denoted the inner, proprioceptive bodily sensations, but also an original unity of the senses, which has been rediscovered by recent infant research as intermodal sensory perception. The affection of the body was thus regarded as the common basis of all sensation.Looking on this track for a bodily basis of the common sense, we find it in the habitual structure of the lived-body as analysed by Merleau-Ponty (1945). The body is the primary "matter-of-course," namely, the tacitly functioning medium of our everyday being-in-the-world prior to any subject-object split. The body schema, in Merleau-Ponty's view, is not only a system of familiar units of movement or "kinetic melodies," it also incorporates the surrounding things, tools, and spaces that are familiar to us and that we "inhabit." Thus, the musician "does not only manipulate the instrument like a separate object, but lives in it like a limb and inhabits the expressive musical space it opens" (Behnke 1997). But for Merleau-Ponty, the body schema is also the basis of "intercorporeity," i.e., a prepersonal sphere of reciprocal comportment and understanding prior to any explicit consensus and symbolic communication. In this sphere of elementary contact, the "atmospheric" senses play a major role: The sense of smell (as shown, e.g., by the expression "to scent treason" or in German, "jemand nicht riechen können" [not be able to "smell" or stand someone]) as well as the sense of taste whose ambiguous meaning, mentioned by Blankenburg, points to the bodily basis of the feeling for what is suitable, decent, or aesthetically pleasing. Even the designation of homo sapiens that we give to ourselves is derived from the latin sapere (to taste/to know), and thus shows that the knowledge characteristic for man is not an explicit one, but an intuitive, implicit knowing or "feel" for his surroundings, or as Kant says, an "aesthetic rather than intellectual judgment" (cited by Blankenburg).Polanyi (1967) has analysed this knowledge at the roots of common sense as "tacit knowledge." It is based on processes of Gestalt formation that enable us to grasp unified wholes through their constituting elements without still being aware of the latter. Thus, we understand the facial expression of others immediately but cannot tell from which details. Or we know how [End Page 323] to waltz without knowing the single movements or being able to explain it. Tacit knowledge implies all the taken-for-granted that we have forgotten once it has become our second nature and part of our bodily habits. It is mainly based on the neuronal coupling of single sensori-motor units by repeated perception or action. This unconscious knowing has only recently come to be explored by psychology under the heading of "implicit" or "procedural memory" (Schacter 1987, 1996). It contains familiar styles or "melodies" of moving, perceiving, and being-with-others in which our whole bodily and emotional experience is engaged. There is an atmospheric, "felt" quality about them that cannot be analysed into single elements. Implicit knowledge may, therefore, never be wholly expressed by words—it is only realized in the concrete situation. It may only be circumscribed by expressions such as "how it feels...," "how it is...," e.g., how it is... (shrink)

In the past dozen years a number of theoretical models of schizophrenic symptoms have been proposed, often inspired by advances in the cognitive sciences, and especially cognitive neuroscience. Perhaps the most widely cited and influential of these is the neurocognitive model proposed by Christopher Frith (1992). Frith's influence reaches into psychiatry, neuroscience, and even philosophy. The philosopher John Campbell (1999a), for example, has called Frith's model the most parsimonious explanation of how self-ascriptions of thoughts are subject to errors of identification. (...) "On reflection, it also seems that this is not just one possible theory; it is the simplest theory which has any prospect of explaining the sense of agency, and we ought to work from it, introducing complications only as necessary" (1999a, p. 612). Not everyone agrees. In their recent analysis of alien voices and inserted thoughts in schizophrenia, Stephens and Graham (2000) offer a critique of Frith. Their criticism, however, although serious, is neither deep nor extensive. They outline three points. First, Frith fails to provide an adequate account of why a subject who experiences thought insertion would misattribute that thought to some other agent. Second, Frith does not clarify the distinction between thought insertion and thought influence. And third, Frith fails to explain how a subject can claim both that he is thinking the thought and that the thought is someone else's thought (Stephens and Graham.. (shrink)

Je lui ai associÉ un court extrait d'une revue de questions portant sur le même thème. Implicit memory is revealed when previous experiences facilitate perf on a task that does not require conscious or intentional recollection of those expces. Explicit memory is revealed when perf on a task requires conscious recolelction of previous expces. Il s'agit de defs descriptives qui n'impliquent pas l'existence de deux systs de mÉmo sÉparÉs. Historiquement Descartes est le premier ˆ faire mention de phÉnomènes de mÉmo (...) implicites, Leibniz, Maine de Biran, Bergson en ont Également parlÉ. Korsakoff (1889) avec ses travaux sur les amnÉsiques montre qu'ils sont capables d'utiliser de l'info qu'ils ont acquises dans des Épisodes rÉcents sans pour autant manifester le moindre souvenir de l'Épisode. L'interprÉtation de ces phÉnomènes Était alors que ça renvoyait ˆ des traces en mÉmoire trop tÉnues pour accèder jusqu'au champ de la conscience. Cette interprÉtation va pouvoir être ÉcartÉe par les travaux rÉcents. Thorndike a Également conduit un nbre important de travaux sur MI. Les trauvaux un peu plus rÉcents ont montrÉ qu'un apprentissage antÉrieur pouvait faciliter une perfce sans qu'il y ait ref explicite à l'Épisode d'apprentissage. On a montrÉ aussi l'effet de stimuli subliminaux, qui en tant que tels ne peuvent pas être rappelÉs consciemment, mais qui influencent la conduite ou les jugts ultÉrieurs. Par ex, la prÉsentation de formes sur des temps très courts qui excluent la possibilitÉ d'une perception consciente influence significativement lechoix de formes dans une pÉreuve ultÉrieure de choix forcÉs où les sjts doivent indiquer la forme qu'il prÉfère entre deux. Ils choisissent prÉfÉrentiellement celles qui leur ont ÉtÉ prÉsentÉes de manière subliminale. De même Bargh et al. ont montrÉ que des sjts soumis de manière subliminale ˆ des mots hostiles portent ultÉrieurement des jugts plus nÉgatifs sur une personne target. Il ya Également eu des travaux sur l'apprsge ou le condt without awareness en particulier apprsge implicite de règles de grammaire (ie le sjt peut construire de nouvelles phrases conformes ˆ la syntaxe de celles qui lui ont ÉtÉ prÉsentÉes sans pour autant petre capables d'noncer les règles de grammaire qu'il utilise) Rem: N'est ce pas un pbe de typemÉtacognition??? Enfin, tous les travaux sur le priming sont des elts en faveur de MI: Facilitation in the processing of a stimulus as a function of a recent encounter with the same stimulus. Type de perfce sur lesquels les effets de priming ont ÉtÉ dÉmontrÉs: -T‰ches de dÉcision lexicale: Le sjt doit dire si la cha"ne de caractères qu'on lui prÉsente est un mot ou pas: Le temps de latence est beaucoup plus court si la cha"ne a dÉjˆ ÉtÉ prÉsentÉe une première fois. -Mesures de temps d'identification de mots en rpÉsentation tachitoscopiques -ComplÉmentation de mots: les sjts ont tendance ˆ complÉter pour crÉer les mots qui leur ont ÉtÉ prÉsentÉs antÉrieurement. L'intÉrêt pour le paradigme de priming se retouve chez les gens qui s'intÉressent ˆ: -reconnaissance de mots et organisation lexicale. les effets de priming permettent de faire des hyps sur l'accès lexical et la reprÉsentation. -M. Épisodique: travux sur les amnÉsiques qui ne se souviennent pas qu'on vient de leur prÉsenter des mots mais qui manifestent une mÉmoire implicite lorsqu'on leur fait faire de la complÉmentation de mots. DISSOCIATION ENTRE M.I. ET M EXPLICITE 1-Si de nombreux travaux montrent que la M explicite est influencÉe par le travail d'Élaboration (profondeur de traitement) en jeu pendant la première phase d'Étude des stimuli, il semble que la MI ne le soit pas. 2-Le changt de modalitÉ (par ex auditif -> visuel) entre la phase d'Étude et la phase de test provoque une attÉnuation importante de l'effet de priming si le test est un test de MI mais pas si c'est un test de ME. 3-Les effets de primings persistent assez largement sur plusieurs jours ce qui n'est pas le cas des perfces ˆ une Épreuve de reconnaissance. 4-Les perfces sur des tests de MI ne semblent pas influencÉes par des manipulations d'interfÉrences proactives ou rÉtroactives dont on sait qu'elles influencent les perfces en ME. 5-Absce de corrÉlation entre perfces ˆ des tests de reconnaissance et perfces ˆ une Épreuve de complÉmentation de mots. SIMILARITES ENTRE PRIMING ET REMEMBERING 1- A certaines conditions les durÉes de rÉtention on des effets parallèles sur les effets de priming et les mesures de ME (REm: en partie contradictoire avec 3 ci dessus) 2-La manipulation du contexte de la liste lors de la phase d'Étude affecte ˆ la fois les perfces en reconnaissance et en identification de mots. 3- ME et MI sont influencÉes par des associations nouvellement acquises entre des paires de mots non reliÉes (Rem: contradictoires avec 4 ci dessus ??) 4- Rem: Le contraire de 1 du pt "dissociation" !!!! dans une manip particulière 5-Johnston et al. ont montrÉ que des mots identifÉs plus rapidement Étaient plus svt jugÉs comme 'old' dans une t‰che de reconnaissance que les mots identifiÉs plus lentement. Il n'est pas exclu que les phÉnomènes que l'on interprètent comme relevant de MI soient parfois de la ME involontaire cad des cas o les cues fournis dans le test conduisent ˆ un souvenir involontaire mais totalement conscient. LES INTERPRETATIONS THEORIQUES DE MI 1-Les effets de priming sur des test de MI sont attribuables ˆ l'activation temporaires de reprÉsentations ou structures de K prÉ-existantes . Cette activation est supposÉe avoir lieu de manière automatique, indÉpendamment des processus d'Élaboration nÉcessaires pour Établir de nouvelles traces Épisodiques. 2- les difÉrences entre ME et MI sont dues ˆ la nature et aux relations entre les processus d'encodage et de rÉcupÉration. Une version de cette approche est celle qui s'appuie sur la distinction entre processus dirigÉs par les donnÉes et processus dirigÉs par les concepts. Ces derniers reflètent des activitÉs initiÉes par le sjt comme l'Élaboration, l'organisation et la reconstruction, c'est sur ce type de processus que reposerait la ME alors que la MI reposerait sur des processus data-driven. 3-ME et MI renvoient ˆ des systs sous jacents diffÉrents. Pour Cohen & Squire (1984), la ME est supportÉe par une M DECLARATIVE , syst qui est en jeu dans la formation de nouvelles reprÉsentations. La MI repose sur un syst PROCEDURAL dans lequel la M se manifeste par des modifications on line de procÉdures ou opÉrations de traitement. Le syst de M Épisodique est vu comme la base pour le souvenir explicite d'evts rÉcents tandis que la M sÉmantique est responsable des perfces sur des tests de MI. Chacune de ces approches est conforme ˆ certaines des donnÉes recueillies mais pas ˆ d'autres. (shrink)

Most cognitive scientists are committed to some version of representationalism, the view that intelligent behavior is caused by internal processes that involve computations over representations. Phenomenologists, however, argue that certain types of intelligent behavior, engaged coping skills, are nonrepresentational. Recent neuroscientific work on multiple memory systems indicates that while many types of intelligent behavior are representational, the types of intelligent behavior cited by phenomenologists are indeed nonrepresentational. This neuroscientific research thus vindicates a key phenomenological claim about the nature of intelligent (...) behaviour. It also provides a framework for the ongoing reconciliation of cognitive science and phenomenology. (shrink)
