Perfected science is but an idealization that provides a useful contrast to highlight the limited character of what we do and can attain. This lies at the core of various debates in the philosophy of science and Rescher’s discussion focuses on the question: how far could science go in principle—what are the theoretical limits on science? He concentrates on what science can discover, not what it should discover. He explores in detail the existence of limits or limitations on scientific inquiry, (...) especially those that, in principle, preclude the full realization of the aims of science, as opposed to those that relate to economic obstacles to scientific progress. Rescher also places his argument within the politics of the day, where "strident calls of ideological extremes surround us," ranging from the exaggeration that "science can do anything"—to the antiscientism that views science as a costly diversion we would be well advised to abandon. Rescher offers a middle path between these two extremes and provides an appreciation of the actual powers and limitations of science, not only to philosophers of science but also to a larger, less specialized audience.

The following points are discussed in response to the commentaries: (1) A taxonomy of perceptual completion phenomena should rely on both phenomenological and mechanistic criteria. (2) Certain forms of perceptual completion are caused by topographically organized neural processes the view that there must be a pictorial or spatial neural-perceptual isomorphism at the bridge locus – should be rejected. Although more abstract kinds of isomorphism are central to the neural-perceptual mapping, the perceptual cannot be exhaustively explained in terms of the neural, (...) and therefore the explanation of perception cannot be reduced to uncovering neural-perceptual isomorphisms. (5) The task of vision is to guide action in the world, not to construct a detailed world-model in the head. (6) Neural filling-in facilitates the integration of information and thereby helps the animal find out about its environment. (7) Perceptual content needs to be understood at the level of the person or animal interacting in the world. (shrink)

There are two fundamental aspects of the notion of a self: it is the owner of one's experiences, that to which one's experiences are properly attributed, and it perceives itself. is a condition on the self's being capable of attributing experiences to itself or being introspectively aware of its experiences, which constitutes a third, higher-order aspect of the self. I claim that it is a common sense assumption, enshrined in the use of 'I', that one's body satisfies the first two (...) aspects. I then argue that these two aspects are not really satisfied by one's body, which is essentially a human organism. Nor are they satisfied by anything of any other kind. So we are not identical to things of any kind, since one can be identical only to that which is one's self or is the referent of one's uses of, 'I'. (shrink)

This paper is about the neglected question of what sort of things we are metaphysically speaking. It is different from the mind-body problem and from familiar questions of personal identity. After explaining what the question means and how it differs from others, the paper tries to show how difficult it is to give a satisfying answer.

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.

A review of Andrew Melnyk's _A Physicalist Manifesto_ (Cambridge: CUP, 2003).

This book argues that we are not equipped to understand the workings of conciousness, despite its objective naturalness.

What are the most fundamental features of the world? Do minds stand outside the natural order? Is a unified picture of mental and physical reality possible? The Mind in Nature provides a staunchly realist account of the world as a unified system incorporating both the mental and the physical.

The Mind in Nature has two central aims. First, that of defending a ‘basic ontology’. Second, having advanced a plausible ontological framework, to appeal to it to cast light on the status of intentionality and the nature of consciousness, paying particular attention to the question of what distinguishes conscious systems from those that are vegetative.Central to Martin's basic ontology is his acceptance of a realist conception of dispositionality. Contrary to the view of David Lewis and others, talk about a thing's (...) dispositions cannot be analysed as talk about a thing's behaviour in a set of counterfactual circumstances. The account of dispositions that emerges from Martin's discussion is one according to which a specific disposition is either actual or it is not. To be actual a disposition need not be manifesting any manifestation. Unmanifesting dispositions are not, therefore, unactualized possibilia – a description which, he observes, is more fitting of unmanifested manifestations. In advancing a realist conception of dispositionality, Martin also opposes those who maintain that dispositional properties reduce to …. (shrink)

Beginning with a sustained argument against the tenseless theory of time and against McTaggart's A series/B series distinction, the author of this essay goes on to provide a non-paradoxical, tensed, phenomenologically-based account of the going on or taking place of events in time that escapes the paradoxes endemic to passage as understood via the A series/B series distinction.

Knowledge of many facts does not amount to understanding unless one also has a sense of how the facts fit together. This aspect of coherence among scientific observations and theories is usually overlooked in summaries of scientific method, since the emphasis is on justification and verification rather than on understanding. I argue that the inter-theoretic coherence, as the hallmark of understanding, is an essential and informative component of any accurate description of science.

Pain asymbolics feel pain, but act as if they are indifferent to it. Nikola Grahek argues that such patients present a clear counterexample to motivationalism about pain. I argue that Grahek has mischaracterized pain asymbolia. Properly understood, asymbolics have lost a general capacity to care about their bodily integrity. Asymbolics’ indifference to pain thus does not show something about the intrinsic nature of pain ; it shows something about the relationship between pains and subjects, and how that relationship might break (...) down. I explore the consequences of such a view for both motivationalism and the categorization of pain asymbolia as a syndrome, arguing for a close link between asymbolia and various forms of depersonalization.

Memory of past episodes provides a sense of personal identity — the sense that I am the same person as someone in the past. We present a neurological case study of a patient who has accurate memories of scenes from his past, but for whom the memories lack the sense of mineness. On the basis of this case study, we propose that the sense of identity derives from two components, one delivering the content of the memory and the other generating (...) the sense of mineness. We argue that this new model of the sense of identity has implications for debates about quasi-memory. In addition, articulating the components of the sense of identity promises to bear on the extent to which this sense of identity provides evidence of personal identity. (shrink)

In this paper we argue that autobiographical memory can be conceptualized as a mental state resulting from the interplay of a set of psychological capacities?self-reflection, self-agency, self-ownership and personal temporality?that transform a memorial representation into an autobiographical personal experience. We first review evidence from a variety of clinical domains?for example, amnesia, autism, frontal lobe pathology, schizophrenia?showing that breakdowns in any of the proposed components can produce impairments in autobiographical recollection, and conclude that the self-reflection, agency, ownership, and personal temporality are (...) individually necessary and jointly sufficient for autobiographical memorial experience. We then suggest a taxonomy of amnesic disorders derived from consideration of the consequences of breakdown in each of the individual component processes that contribute to the experience of autobiographical recollection.

In Mind and Body Robert Kirk offers an introduction to the complex tangle of questions and puzzles roughly labelled the mind-body problem.

This comprehensive reference provides an exhaustive guide to current scholarship on the perennial problem of Free Will--perhaps the most hotly and voluminously debated of all philosophical problems. While reference is made throughout to the contributions of major thinkers of the past, the emphasis is on recent research. The essays, most of which are previously unpublished, combine the work of established scholars with younger thinkers who are beginning to make significant contributions. Taken as a whole, the Handbook provides an engaging and (...) accessible roadmap to the state of the art thinking on this enduring topic. (shrink)

This book traces how such a seemingly immutable idea as measurement proved so malleable when it collided with the subject matter of psychology. It locates philosophical and social influences reshaping the concept and, at the core of this reshaping, identifies a fundamental problem: the issue of whether psychological attributes really are quantitative. It argues that the idea of measurement now endorsed within psychology actually subverts attempts to establish a genuinely quantitative science and it urges a new direction. It relates views (...) on measurement by thinkers such as Holder, Russell, Campbell and Nagel to earlier views, like those of Euclid and Oresme. Within the history of psychology, it considers contributions by Fechner, Cattell, Thorndike, Stevens and Suppes, among others. It also contains a non-technical exposition of conjoint measurement theory and recent foundational work by leading measurement theorist R. Duncan Luce. (shrink)

Although philosophical approaches to the self are diverse, several of them are relevant to cognitive science. First, the notion of a 'minimal self', a self devoid of temporal extension, is clarified by distinguishing between a sense of agency and a sense of ownership for action. To the extent that these senses are subject to failure in pathologies like schizophrenia, a neuropsychological model of schizophrenia may help to clarify the nature of the minimal self and its neurological underpinnings. Second, there is (...) good evidence to suggest that although certain aspects of the minimal self are primitive and embodied, other aspects may be accessed only in reflective consciousness. Employing a modified concept of the minimal self, it may be possible to construct a robotic form of non-conscious self-reference that depends on an interaction between the robotic body and its environment. In contrast to the minimal self, the narrative self involves continuity over time and is directly relevant to discussions of memory and personal identity. There is growing consensus among philosophers and cognitive scientists about the importance of narrative and its relation to episodic memory and left-hemisphere functions. There are, however, at least two different views of how the narrative self is structured. On one model it is nothing more than an abstract point. On a more extended view, proposed here, the self is a rich amalgam of narratives that allows for the equivocations, contradictions, and self-deceptions of personal life. Even in this case, however, neurocognitive models contribute to our understanding of how narrative identity is structured. (shrink)

Paul Feyerabend's globally acclaimed work, which sparked and continues to stimulate fierce debate, examines the deficiencies of many widespread ideas about scientific progress and the nature of knowledge. Feyerabend argues that scientific advances can only be understood in a historical context. He looks at the way the philosophy of science has consistently overemphasized practice over method, and considers the possibility that anarchism could replace rationalism in the theory of knowledge. -- Amazon.com.

In this paper I discuss the nature of the “I” (or “self”) and whether it is presupposed by the very existence of conscious experiences (as that which “has” them) or whether it is, instead, in some way constituted by them. I argue for the former view and try to show that the very nature of experience implies a non-constituted synchronic and diachronic transcendence of the experiencing “I” with regard to its experiences, an “I” which defies any objective characterization. Finally I (...) suggest that the self, though irreducible to inter-experiential relations, is not a “separately existing entity”, but should be conceived of as a dimension , namely the dimension of first-personal manifestation of the experiences.
