Aron Gurwitsch’s theory of the structure and dynamics of consciousness has much to offer contemporary theorizing about consciousness and its basis in the embodied brain. On Gurwitsch’s account, as we develop it, the field of consciousness has a variable sized focus or "theme" of attention surrounded by a structured periphery of inattentional contents. As the field evolves, its contents change their status, sometimes smoothly, sometimes abruptly. Inner thoughts, a sense of one’s body, and the physical environment are dominant field contents. (...) These ideas can be linked with (and help unify) contemporary theories about the neural correlates of consciousness, inattention, the small world structure of the brain, meta-stable dynamics, embodied cognition, and predictive coding in the brain.

Evidence and theory ranging from traditional philosophy to contemporary cognitive research support the hypothesis that consciousness has a two-part structure: a focused region of articulated experience surrounded by a field of relatively unarticulated, vague experience.William James developed an especially useful phenomenological analysis of this "fringe" of consciousness, but its relation to, and potential value for, the study of cognition has not been explored. I propose strengthening James′ work on the fringe with a functional analysis: fringe experiences work to radically condense (...) context information in consciousness; are vague because a more explicit representation of context information would overwhelm consciousness′ limited articulation capacity; help mediate retrieval functions in consciousness; and contain a subset of monitoring and control experiences that cannot be elaborated in focal attention and are "ineffable." In general, the phenomenology of the fringe is a consequence of its cognitive functions, constrained by consciousness′ limited articulation capacity. Crucial to monitoring and control is the feeling of "rightness." Rightness functions as a summary index of cognitive integration, representing, in the fringe, the degree of positive fit between a given conscious content and its parallel, unconsciously encoded context. Rightness appears analogous to the connectionist metric of global network integration, known variously as goodness-of-fit, harmony, or minimum energy. (shrink)

61 subjects were given the task of solving a problem having four possible solutions. "Two cords were hung from the ceiling, and were of such length that they reached the floor. One hung near a wall, the other from the center of the room. The subject was told, 'Your problem is to tie the ends of these two strings together.' He soon learned that if he held either cord in his hand he could not reach the other. He was then (...) told that he could use or do anything he wished." A number of objects which might help in the solution of the problem were present in the room. After each solution had been mastered the subject was told to solve the problem in still another way until all of the solutions had been learned. The trials were timed and introspective reports concerning the means of solution were recorded. A number of hints were given from time to time when the subject failed to reach a solution. The author's conclusions are to the effect that "The perception of the solution of a problem is like the perceiving of a hidden figure in a puzzle-picture. In both cases the perception is sudden; there is no conscious intermediate stage; and the relationships of the elements in the final perceptions are different from those which preceded, i.e., changes in meaning are involved." The author feels that trial and error or association by similarity cannot explain his results. (shrink)

This paper explores whether consciousness can exist without attention. This is a hot topic in philosophy of mind and cognitive science due to the popularity of theories that hold attention to be necessary for consciousness. The discovery of a form of consciousness that exists without the influence of attention would require a change in the way that many global workspace theorists, for example, understand the role and function of consciousness. Against this understanding, at least three forms of consciousness have been (...) argued to exist without attention: perceptual gist, imagistic consciousness, and phenomenal consciousness. After first arguing that the evidence is inconclusive on the question of whether these forms of consciousness exist without attention, I here present a fourth form of consciousness that is likely to be more successful: conscious entrainment. I argue that conscious entrainment is a form of consciousness associated with skilled behavior in which attention is sometimes absent. (shrink)

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

First Published in 1999. Routledge is an imprint of Taylor & Francis, an informa company.

This collection explores the structure of consciousness and its place in the world, or inversely the structure of the world and the place of consciousness in it. Amongst the topics covered are: the phenomenological aspects of experience, dependencies between experience and the world and the basic ontological categories found in the world at large. Developing ideas drawn from historical figures such as Descartes, Husserl, Aristotle, and Whitehead, the essays together demonstrate the interdependence of ontology and phenomenology and its significance for (...) the philosophy of mind.

Phenomenology is the study of structures of consciousness as experienced from the first-person point of view. The central structure of an experience is its intentionality, its being directed toward something, as it is an experience of or about some object. An experience is directed toward an object by virtue of its content or meaning (which represents the object) together with appropriate enabling conditions.

This study explores the interface between conscious and nonconscious mental processes using phenomenological analysis, information processing cognitive psychology, connectionism and traditional aesthetic theories. It attempts to explain how global, evaluative information--especially the primitive feeling of 'rightness' or 'making sense'--is represented in consciousness. ;Many lines of evidence confirm and extend William James' nucleus/fringe model of consciousness: surrounding clear experience in focal attention is a fringe of vague experience. Context information in general, and the feeling of rightness in particular, occupy the fringe. (...) The fringe is vague because it works to finesse consciousness' limited capacity to articulate experience, and the fringe is elusive or 'ungraspable' because it helps to call new information into consciousness. The phenomenology of the fringe is thus a consequence of its cognitive functions. ;Meaningfulness is proposed to be a summary index of cognitive integration, signalling consciousness about the degree of global compatibility or 'fit' between a given content in the focus of attention and its nonconscious context. Though very similar to goodness-of-fit in a connectionist network, Meaningfulness is proposed to play an active feedback role in cognition, while goodness-of-fit, as currently used, is a passive measure of network integration. ;This analysis predicts that an intense feeling of Meaningfulness will have a characteristic 'profile,' and this profile is evident in many accounts of aesthetic experience: a feeling of unity and coherence that cannot be captured adequately in words, but which nevertheless seems to be a source of profound, and often "spiritual," knowledge. ;Many philosophical theories try to explain the unistic, ineffable, noetic, and transcendent aspects of the aesthetic. Platonic and Aristotelian traditions are considered, but the primary focus is on Kant. The Critique of Judgment created modern aesthetics, and in many ways it is remarkably compatible with current cognitive analysis. ;Beyond clarifying the cognitive foundation of aesthetic experience, this study offers new arguments against epiphenomenalism, provides further reason to doubt rule-based accounts of nonconscious processing, explains the isomorphism in aesthetic and mystical phenomenology, and develops a method to investigate consciousness called convergent phenomenology.

It is always risky to make sweeping statements about the development of philosophy, but if one were nevertheless asked to describe 20th century philosophy in broad strokes, one noteworthy feature might be the following: Whereas important figures at the beginning of the century, figures such as Frege and Husserl, were very explicit in their rejection of naturalism (both are known for their rejection of the attempt to naturalize the laws of logic, i.e., for their criticism of psychologism), the situation has (...) changed considerably. Today many philosophers – not the least within analytical philosophy – would subscribe to some form of naturalism. In fact, naturalism is seen by many as the default metaphysical position. If you don’t subscribe to naturalism you must be subscribing to some form of Cartesian substance dualism. Thus, whereas 20 or 30 years ago one might have been inclined to characterize the development of 20th century philosophy in terms of a linguistic turn, a turn from a philosophy of subjectivity to a philosophy of language, it might today be more apt to describe the development in terms of a turn from anti-naturalism to naturalism.

Non-sensory experiences represent almost all context information in consciousness. They condition most aspects of conscious cognition including voluntary retrieval, perception, monitoring, problem solving, emotion, evaluation, meaning recognition. Many peculiar aspects of non-sensory qualia (e.g., they resist being 'grasped' by an act of attention) are explained as adaptations shaped by the cognitive functions they serve. The most important nonsensory experience is coherence or "rightness." Rightness represents degrees of context fit among contents in consciousness, and between conscious and non-conscious processes. Rightness (not (...) familiarity) is the feeling-of-knowing in implicit cognition. The experience of rightness suggests that neural mechanisms "compute" signals indicating the global dynamics of network integration. (shrink)
