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)

Self-knowledge is based on several different forms of information, so distinct that each one essentially establishes a different 'self. The ecological self is the self as directly perceived with respect to the immediate physical environment; the interpersonal self, also directly perceived, is established by species-specific signals of emotional rapport and communication; the extended self is based on memory and anticipation; the private self appears when we discover that our conscious experiences are exclusively our own; the conceptual self or 'self-concept' draws (...) its meaning from a network of socially-based assumptions and theories about human nature in general and ourselves in particular. Although these selves are rarely experienced as distinct (because they are held together by specific forms of stimulus information), they differ in their developmental histories, in the accuracy with which we can know them, in the pathologies to which they are subject, and generally in what they contribute to human experience.

What makes this work so important is that it returned the body to the forefront of philosophy for the first time since Plato.

A bodily self is characterized by pre-reflective bodily self-consciousness that is.

Challenging and rewarding in equal measure, _Phenomenology of Perception_ is Merleau-Ponty's most famous work. Impressive in both scope and imagination, it uses the example of perception to return the body to the forefront of philosophy for the first time since Plato. Drawing on case studies such as brain-damaged patients from the First World War, Merleau-Ponty brilliantly shows how the body plays a crucial role not only in perception but in speech, sexuality and our relation to others.

Perhaps above all, Merleau-Ponty's (...) insights about the embodied mind are a bold and refreshing challenge to the new era of virtual reality and artificial intelligence, as scientists and psychologists discover the centrality of the body to mind and intelligence.

Reexamines the Western philosophical tradition, looking at the basic concepts of the mind, time, causation, morality, and the self.

Phenomenological psychiatry has suffered from a failure to translate its insights into terms specific enough to be applied to psychiatric diagnosis or to be used in contemporary research programs. This difficulty can be understood in light of the well-known tradeoff between reliability and validity. We argue, however, that with sufficient ingenuity, phenomenological concepts can be adapted and applied in a research context. Elsewhere, we have described a phenomenologically oriented conception of schizophrenia as a self- or ipseity-disorder with two main facets: (...) decline in the sense of existing as a subject of awareness (diminished self-affection) and heightened awareness of aspects of experience that would normally remain tacit or presupposed (hyperreflexivity). This approach is consistent with Minkowski, Blankenburg, and Kimura and offers one possible synthesis of their views. Here we describe two areas of empirical research that are congruent with, or actually inspired by, a phenomenological approach emphasizing such disorders of consciousness and self-experience: (1) Phenomenologically oriented, interview studies show that, whereas negative-symptom patients generally deny any diminishment of affect and thinking, they do describe qualitative alterations of experience suggestive of hyperreflexivity and diminished self-affection. (2) Another line of research suggests that the early detection of schizophrenic symptoms may be enhanced by adopting a phenomenological approach. (shrink)
