In this speculative paper I would like to show how important the integration of mental content is for a theory of phenomenal consciousness. I will draw the reader's attention to two manifestations of this problem which already play a role in the empirical sciences concerned with consciousness: The binding problem and the superposition problem. In doing so I hope to be able to leave the welltrodden paths of the debate over consciousness. My main concern is to gain a fresh access (...) to the familiar theoretical difficulties associated with the concept of 'consciousness'. (shrink)

Sommario. Prima che di definire un modello della coscienza e comprendere che cosa sia un fenomeno soggettivo, è necessario sviluppare una teoria della prospettiva in prima persona. Questa teoria deve essere concettualmente con- vincente, empiricamente plausibile e, soprattutto, aperta a nuovi sviluppi. Il quadro di riferimento concettuale deve essere coerente con il progresso scienti- fico. Le sue ipotesi fondamentali devono essere adattabili in modo da permette- re a nuovi risultati sperimentali di essere inseriti nel modello teorico. Questo ar- ticolo tenta (...) di definire le linee generali di una teoria in grado di offrire un’analisi rappresentazionale della prospettiva in prima persona. Tre proprietà fenomeniche sono centrali a quest’analisi: “egoicità” (la proprietà fenomenica; il senso di possesso di una sensazione), “selfhood” (l’esperienza cosciente di essere qualcuno) e la prospetticità (una caratteristica strutturale: il fatto che lo spazio fenomenico appaia organizzato attorno a un centro, una prospettiva su- per-modale). Questo articolo analizza queste proprietà da un punto di vista sia rappresentazionale che funzionale. Introdurrò nuovi vincoli concettuali per le rappresentazioni fenomeniche e due entità teoriche necessarie per capire che cosa sia la prospettiva in prima persona: “il modello fenomenico del sé” (PSM: phenomenal self model) e il “modello fenomenico della relazione intenzionale” (PMIR: phenomenal model of intentional relation). Un modello fenomenico del sé è una struttura rappresentazionale plurimodale, il cui contenuto costituisce il contenuto dell’esperienza del sé cosciente. Ha due caratteristiche importanti. Primo, è l’unica struttura rappresentazionale ancorata nel cervello da un colle- gamento funzionale permanente. Secondo, parti consistenti del PSM sono fe- nomenicamente trasparenti: non posso essere identificate come rappresentazioni all’interno del sistema. Sono intrappolate in quello che è stato definito un “in- genuo realismo auto-ingannevole”.. (shrink)

differences between dreaming and waking consciousness as well. In this chapter, we will argue that these differences mainly concern the subjective quality of the dreaming experience. The interesting question, from a philosophical point of view, is not so much whether or not dreams are conscious experiences at all. Rather, one must ask in what sense dreams can be considered as conscious experiences, and what happens to the experiential subject during the dream state. Finally, in order to arrive at a more (...) differentiated understanding of dream consciousness, we will contrast our analysis of ordinary dreams with lucid dreams, as well as with the varying degrees of lucidity and cognitive clarity seen in semi-lucid and prelucid dreams.

Of all the current philosophical attempts to rescue the concept of “self” by working out a weaker version, one that does not imply an ontological substance or an individual in the metaphysical sense, Marcello Ghin’s is clearly my favorite. His reconstruction of the original theory is absolutely accurate and without any major misunderstandings. Enriching the concept of a “SMT-system” with the notions of “autocatalysis” and “self- sustainment,” and adding the intriguing idea that we are systems reflecting these processes on a (...) new level of complexity, namely with the help of an integrated PSM on the level of conscious experience, seems the way to go if one wants to keep the concept of “self.” I have great difficulties in writing a reply to Ghin’s commentary, simply because I agree with so much in it. Let us see where his approach leads us. (shrink)

Gallagher is right in pointing out that scientific realism is an implicit background assumption of BNO, and that I did not give an independent argument for it. He is also right in saying that science does not _demonstrate_ the existence of certain entities, but that it assumes those entities in a process of explanation and theory formation. However, it is not true that science, as Gallagher writes (p.2), “simply” assumes the reality of certain things: such assumptions are embedded in the (...) context of an attempt to find the_ minimal _ set of ontological assumptions one has to make relative to a set of explanatory goals and relative to a specific data set in a certain domain. This parsimonious spirit is also the <blockquote> PSYCHE: http://psyche.cs.monash.edu.au/ </blockquote> spirit of SMT, which can be seen as a search for the minimal conditions under which a phenomenal self and a consciously experienced first-person perspective can emerge.

Contemporary philosophical and scienti .c discussions of mind developed from a 'proto-concept of mind ',a mythical,tradition- alistic,animistic and quasi-sensory theory about what it means to have a mind. It can be found in many di .erent cultures and has a semantic core corresponding to the folk-phenomenological notion of a 'soul '.It will be argued that this notion originates in accurate and truthful .rst-person reports about the experiential content of a special neurophenomenological state-class called 'out-of-body experiences '.They can be undergone by (...) every human being and seem to possess a culturally invariant cluster of functional and phenomenal core properties similar to the proto-concept of mind. The common causal factor in the emergence and development of the notion of the soul and the proto-concept of mind may consist in a yet to be determined set of properties realized by the human brain, underlying the cluster of phenomenal properties described in the relevant first-person reports. This hypothesis suggests that such a neurofunctional substrate ed human beings at different times, and in widely varying cultural contexts, to postulate the existence of a soul and to begin developing a theory of mind.

This is a short sketch of some central ideas developed in my recent book _Being No One_ (BNO hereafter). A more systematic summary, which focuses on short answers to a set of specific, individual questions is already contained _in _the book, namely as BNO section 8.2. Here, I deliberately and completely exclude all work related to semantically differentiating and empirically constraining the philosophical concept of a "quale" (mostly Chapter 2, 3 & 8), all proposals regarding conceptual foundations for the overall (...) theory (2 & 5), all of the neurophenomenological case-studies used to test and refine it (4 & 7), and all remarks of a more general or methodological character (1 & 8).

To speak of “inferences,” “interpretations,” and so forth is just folk psychology. It creates new homunculi, and it is also implausible from a purely phenomenological perspective. Phenomenal volition must be described in the conceptual framework of an empirically plausible theory of mental representation. It is a non sequitur to conclude from dissociability that the functional properties determining phenomenal volition never make a causal contribution.

Before one can even begin to model consciousness and what exactly it means that it is a subjective phenomenon one needs a theory about what a first-person perspective really is. This theory has to be conceptually convincing, empirically plausible and, most of all, open to new developments. The chosen conceptual framework must be able to accommodate scientific progress. Its ba- sic assumptions have to be plastic as it were, so that new details and empirical data can continuously be fed into (...) the theoretical model as it grows and becomes more refined. This paper makes an attempt at sketching the outlines of such a theory, offering a representationalist analysis of the phenomenal first-person perspective. Three phenomenal target properties are centrally relevant:. (shrink)

The representational dynamics of the brain is a subsymbolic process, and it has to be conceived as an "agent-free" type of dynamical self-organization. However, in generating a coherent internal world-model, the brain decomposes target space in a certain way. In doing so, it defines an "ontology": to have an ontology is to interpret a world. In this paper we argue that the brain, viewed as a representational system aimed at interpreting the world, possesses an ontology too. It decomposes target space (...) in a way that exhibits certain invariances, which in turn are functionally significant. A challenge for empirical research is to determine which are the functional regularities guiding this decomposition process. What are the explicit and implicit assumptions about the structure of reality, which at the same time shape the causal profile of the brain's motor output and the representational deep structure of the conscious mind arising from it (its "phenomenal output")? How do they constrain high-level phenomena like conscious experience, the emergence of a first-person perspective, or social cognition? By reviewing a series of neuroscientific results, we focus on the contribution the motor system makes to this process. As it turns out, the motor system constructs goals, actions, and intending selves as basic constituents of the world it interprets. It does so by assigning a single, unified causal role to them. Empirical evidence now clearly shows how the brain actually codes movements and action goals in terms of multimodal representations of organism-object relations. Under a representationalist analysis, this process can be interpreted as an internal representation of the intentionality relation itself. We try to show how such a more complex form of representational content, once it is in place, can later function as the building block for social cognition and a for more complex, consciously experienced representation of the first-person perspective as well. The motor system may therefore play a decisive role in understanding how the functional ontology of the human brain could be gradually extended into the subjective and social domains. (shrink)

Dies ist kein wissenschaftlicher Text im engeren Sinne. Im Gegenteil: Das erste Ziel dieses Beitrags besteht zuerst darin, auf möglichst kurze und allgemeinverständliche Weise eine neue Problemlage zu skizzieren, die mit zunehmender Geschwindigkeit an Bedeutung gewinnt. Zweitens möchte ich einen vorläufigen Arbeitsbegriff anbieten, den Begriff einer „Bewusstseinskultur“. Dieser neue Begriff soll dazu dienen, eine Reihe von ganz unterschiedlichen theoretischen und praktischen Strategien zusammenzufassen, die wir meiner Meinung nach benötigen werden, um der fraglichen Herausforderung gerecht zu werden. Der Begriff „Bewusstseinskultur“ soll (...) also zunächst nur eine Diskussionsgrundlage schaffen. Deshalb werde ich an dieser Stelle den schwierigen philosophischen Detailproblemen, die mit der Idee einer Bewusstseinskultur verbunden sind, auch nicht im Ansatz gerecht werden können. Ich hoffe aber, dass die Relevanz des Problems dieses etwas unanalytische und populäre Vorgehen am Ende auch in den Augen meiner eher kritischen Leser rechtfertigt. (shrink)

A representationalist analysis of strong first-person phenomena is developed (Baker 1998), and it is argued that conscious, cognitive self-reference can be naturalized under this representationalist analysis. According to this view, the phenomenal first-person perspective is a condition of possibility for the emergence of a cognitive first-person perspective. Cognitive self-reference always is reference to the phenomenal content of a transparent self-model. The concepts of phenomenal transparency and introspection are clarified. More generally, I suggest that the concepts of phenomenal opacity and phenomenal (...) transparency are interesting instruments for analyzing conscious, self-representational content, and that their relevance in understanding reflexive, i.e., cognitive subjectivity may have been overlooked in the past.

In this contribution I will argue that our traditional, folk-phenomenological concept of a "soul� may have its origins in accurate and truthful first-person reports about the experiential content of a specific neurophenomenological state-class. This class of phenomenal states is called the "Out-of-body experience� (OBE hereafter), and I will offer a detailed description in section 3 of this paper. The relevant type of conscious experience seems to possess a culturally invariant cluster of functional and phenomenal core properties: it is (...) a specific kind of conscious experience, which can in principle be undergone by every human being. I propose that it probably is one of the most central semantic roots of our everyday, folk-phenomenological idea of what a soul actually is. (shrink)

“Identity disorders” constitute a large class of psychiatric disturbances that, due to deviant forms of self-modeling, result in dramatic changes in the patients’ phenomenal experience of their own personal identity. The phenomenal experience of selfhood and transtemporal identity can vary along an extremely large number of dimensions: There are simple losses of content (for example, complete losses of proprioception, resulting in a “bodiless” state of self-consciousness, see Cole 1995, Gallagher and Cole 1995, Sacks 1998). There are also various typologies of (...) phenomenal disintegration as in schizophrenia, in depersonalization disorders and in_ Dissociative Identity Disorder_ (DID), sometimes accompanied by multiplications of the phenomenal self within one and the same physical system. It is important to not only analyze these state-classes in terms of functional deficits or phenomenology alone, but as _self-representational _content as well. For instance, in the second type of cases just mentioned, we confront major redistributions of the phenomenal property of "mineness” in representational space, of what is sometimes also called the “sense of ownership”. Finally, there are at least four different delusions of misidentification (DM1; namely Capgras syndrome, Frégoli syndrome, intermetamorphosis, reverse intermetamorphosis and reduplicative paramnesia). Being a philosopher, I will discuss two particular types of identity disorder

To have an ontology is to interpret a world. In this paper we argue that the brain, viewed as a representational system aimed at interpreting our world, possesses an ontology too. It creates primitives and makes existence assumptions. It decomposes target space in a way that exhibits a certain invariance, which in turn is functionally significant. We will investigate which are the functional regularities guiding this decomposition process, by answering to the following questions: What are the explicit and implicit assumptions (...) about the structure of reality, which at the same time shape the causal profile of the brain's motor output and its representational deep structure, in particular of the conscious mind arising from it (its ''phenomenal output'')? How do they constrain high-level phenomena like conscious experience, the emergence of a first-person perspective, or social cognition? By reviewing a series of neuroscientific results and integrating them with a wider philosophical perspective, we will emphasize the contribution the motor system makes to this process. As it will be shown, the motor system constructs goals, actions, and intending selves as basic constituents of the world it interprets. It does so by assigning a single, unified causal role to them. Empirical evidence demonstrates that the brain models movements and action goals in terms of multimodal representations of organism-object-relations. Under a representationalist analysis, this process can be conceived of as an internal, dynamic representation of the intentionality-relation itself. We will show how such a complex form of representational content, once it is in place, can later function as a functional building block for social cognition and for a more complex, consciously experienced representation of the first-person perspective as well.

Zoltan Jakab has presented an interesting conceptual analysis of the ineffability of qualia in a functionalist and classical cognitivist framework. But he does not want to commit himself to a certain metaphysical thesis on the ontology of consciousness or qualia. We believe that his strategy has yielded a number of highly relevant and interesting insights, but still suffers from some minor inconsistencies and a certain lack of phenomenological and empirical plausibility. This may be due to some background assumptions (...) relating to the theory of mental representation employed. Jakab. (shrink)

Was genau ist eigentlich eine Ich-Störung? Ich werde auf den folgenden Seiten dafür argumentieren, daß man die Natur dieses Typs von psychiatrischen Störungsbildern besser verstehen kann, indem man einen Blick über die medizinischen Fachgrenzen hinweg in die analytische Philosophie des Geistes [1] und in die Kognitionswissenschaft [2] wirft. Beiden Disziplinen ist gemeinsam, daß mentale Zustände dort häufig einer funktionalen Analyse unterzogen und als Informationsverarbeitungsereignisse beschrieben werden. Das bedeutet, daß mentale Zustände dabei zunächst mit Blick auf die kausale Rolle untersucht werden, (...) die sie im System spielen. Das System selbst wird als natürlich entstandenes Informationsverarbeitungssystem mit einer langen biosozialen Geschichte analysiert, welches Repräsentationen der Welt und von sich selbst in ihr erzeugt. Psychiatrische Störungsbilder sind unter dieser Perspektive Störungen des Informationsflusses, insbesondere Störungen in der Art und Weise, in der es die Welt und sich selbst.. (shrink)

The contributions to this book are original articles, representing a cross-section of current philosophical work on consciousness and thereby allowing students and readers from other disciplines to acquaint themselves with the very latest debate, so that they can then pursue their own research interests more effectively.

Metzinger. (shrink)

The article presents a critical survey of the philosophical discussion of the mind-body-problem since the collapse of Rylean behaviourism. The major theories (identity theories, supervenience, emergentist materialism, dualist interactionism and functionalism) are sketched and briefly evaluated with regard to their advantages and disadvantages. The conclusion is that no satisfactory theory about the relation between mental and neurophysiological states exists today, but considerable progress has been made regarding the contours of this cluster of problems. A catalogue of criteria which every future (...) theory concerning the mind-body problem must fulfill is given at the end. (shrink)

As Flanagan remarks at the outset, many philosophers and researchers in the cognitive and neurosciences today believe that a naturalistic solution to the mind-body problem will eventually be found. Optimistic attitudes of this sort are usually inspired by the remarkable theoretical success so far achieved under the information-processing approach. The information-processing approach rests on a number of ubiquitous background assumptions. The most central of these is that treating human beings and their brains as information-processing systems may open precisely those levels (...) of description under which the classical philosophical questions can be reformulated and finally answered. Many philosophers today try to treat traditional puzzles in this field - like the mind-brain-relationship, intentionality or self-awareness - by analyzing them in a top-down-fashion, i.e. by reformulating them in an information-processing terminology. In doing so one of their goals, usually, is eventually to naturalize those theoretical problems, to transform them into problems tractable by empirical science. (shrink)

This is a bibliography of books and articles on consciousness in philosophy, cognitive science, and neuroscience over the last 30 years. There are three main sections, devoted to monographs, edited collections of papers, and articles. The first two of these sections are each divided into three subsections containing books in each of the main areas of research. The third section is divided into 12 subsections, with 10 subject headings for philosophical articles along with two additional subsections for articles in cognitive (...) science and neuroscience. Of course the division is somewhat arbitrary, but I hope that it makes the bibliography easier to use. This bibliography has first been compiled by <span class='Hi'>Thomas</span> Metzinger and David Chalmers to appear in print in two philosophical anthologies on conscious experience (Metzinger 1995a, b). From 1995 onwards it has been continuously updated by <span class='Hi'>Thomas</span> Metzinger, and now is freely available as a PDF-, RTF-, or HTML-file. This bibliography mainly attempts to cover the Anglo-Saxon and German debates, in a non-annotated, fully formatted way that makes it easy to "cut and paste" from the original file. To a certain degree this bibliography also contains items in other languages than English and German - all submissions in other languages are welcome. Last update of current version: July 13th, 2001.
