Gray extrapolates from circuit models of psychopathology to propose neural substrates for the contents of consciousness. I raise three concerns: knowledge of synaptic arrangements may be inadequate to fully support his model; latent inhibition deficits in schizophrenia, a focus of this and related models, are complex and deserve replication; and this conjecture omits discussion of the neuropsychological basis for the contents of the unconscious.

The new methods of modern sciences can contribute to understand the genesis of mental illness, the disturbances in brain chemistry, physiology, anatomy or genetical information underlying different diseases of the nervous system. Understanding mental illness is not only challenging to science, but is also of great social importance. Moreover, the new developments of neurosciences put new lights on discussions such as brain-mind concepts, unity of mind, definition of consciousness and even definition of the person.For the majority of the scientists, it (...) is clear today that the mind can not be conceived any more as unique and indivisible. For philosophers, it is clear also that neuroscience influenced their vision of life and death: neurosciences are not strange to the debate whole-body death versus whole-brain death for instance. Modern scientific achievements have expanded our vision, allowing us to percieve previously unanticipated interrelationships between biological and psychological phenomena. The boundary between some behavioural and higher neural function studies and biology is arbitrary and changing. It has been imposed not by the natural contours of the disciplines, but by lack of knowledge. (shrink)

In the physical sciences a rigorous theory is a hierarchy of descriptions in which causal relationships between many general types of entity at a phenomenological level can be derived from causal relationships between smaller numbers of simpler entities at more detailed levels. The hierarchy of descriptions resembles the modular hierarchy created in electronic systems in order to be able to modify a complex functionality without excessive side effects. Such a hierarchy would make it possible to establish a rigorous scientific theory (...) of consciousness. The causal relationships implicit in definitions of access consciousness and phe- nomenal consciousness are made explicit, and the corresponding causal relationships at the more detailed levels of perception, memory, and skill learning described. Extension of these causal relationships to physiological and neural levels is discussed. The general capability of a range of current consciousness models to support a modular hierarchy which could generate these causal relationships is reviewed, and the specific capabilities of two models with good general capabilities are compared in some detail.

In this essay, the authors describe human consciousness as an embodied experience that emerges from a complex relationship of the biological and the phenomenological. Following arguments made by ) and ), they argue that one primary way that human beings develop self‐awareness of their own minds is by becoming aware of other minds. These mind‐reading abilities become fundamental to the continual adaptations that human beings must make in their daily lives. The authors offer descriptions of two literary texts to illustrate (...) how these texts participate with other forms of culture and with human biology to produce experiences of self‐conscious awareness. They argue that if consciousness is understood as an emergent property of biology and culture, and if human beings develop self‐awareness of their own minds by becoming cognisant of other minds, then it follows that literary experiences create productive mind‐reading practices that contribute to the ongoing development and emergence of consciousness and, as such, are important for education. They conclude that extended opportunities to critically inquire into readers’ imagined identifications with characters and their situations can support the development of empathic understanding of others.

In recent years, there has been increasing discussion of whether philosophy actually makes progress. This discussion has been prompted, in no small part, by the depth and persistence of disagreement among philosophers on virtually every major theoretical issue in the field. In this paper, I examine the role that the Method of Cases – the widespread philosophical method of testing and revising theories by comparing their verdicts against our intuitions in particular cases – plays in creating and sustaining theoretical disagreements (...) in philosophy. Drawing on work from cognitive psychology, I argue that there is a fundamental incompatibility between the structure of the theories that philosophers seek to construct using the MoC and the structure of the concepts on which our case-specific intuitions are based. This incompatibility renders MoC-based philosophical theorizing unable ever to succeed by the very standards of adequacy that it sets for itself. And this, in turn, helps to explain the depth and persistence of theoretical disagreements – and, in certain ways, the lack of progress – in the many areas of philosophy where the MoC plays an important role.

The connection between early yogācāras, or practitioners of yoga, and later Yogācāra-vijñānavāda philosophy has long preoccupied scholars. But these connections remain obscure. This article suggests that a text that has received little attention in modern scholarship, the Saddharmasmṛtyupasthānasūtra, may shed light on aspects of early yogācāra contemplative cultures that gave rise to some of the formative dynamics of Yogācāra-vijñānavāda thought. I show how traditional Buddhist meditative practice and engagement with Abhidharma theoretics come together in the Saddharmasmṛtyuasthānasūtra to produce a novel (...) theory of mind that mirrors many of the philosophical problematics that early and late Yogācāra-vijñānavādins confronted and attempted to work out in śāstric detail.

It is sometimes said that reasoning, thought and judgment essentially involve action. It is sometimes said that they involve spontaneity, where spontaneity is taken to be connected in some constitutive way with action—intentional, voluntary and indeed free action. There is, however, a fundamental respect in which reason, thought and judgment neither are nor can be a matter of action. Any spontaneity that reason, thought and judgment involve can be connected with freedom only when the word 'freedom' is used in the (...) Spinozan-Kantian sense according to which freedom is a matter of 'rational necessitation', determination by reason. (shrink)

Two theories dominate the current debate on group agency: functionalism, as endorsed by Bryce Huebner and Brian Epstein, and interpretivism, as defended by Deborah Tollefsen, and Christian List and Philip Pettit. In this paper, I will give a new argument to favour functionalism over interpretivism. I discuss a class of cases which the former, but not the latter, can accommodate. Two features characterise this class: First, distinct groups coincide, that is numerically distinct groups share all their members at all time. (...) Second, we have access to the inner mechanisms of the groups agents, because members know what they have decided on. I construct a counterexample with these features allowing me to reject interpretivism about group agency in favour of functionalism. (shrink)

Gray unwisely melds together two distinguishable contributions of consciousness: one to epistemology, the other to evolution. He also renders consciousness needlessly invisible behaviorally.

Understanding how conceptual structures inform stone tool production and use would help us resolve the issue of a pongid-hominid dichotomy in brain organisation and cognitive ability. Evidence from ideational apraxia suggests that the planning of linguistic and manipulative behaviours is not colocalized in homologous circuits. An alternative account in terms of the evolutionary expansion of the whole prefrontal-premotor area may be more plausible.

Until relatively recently, it was often supposed that changes in the material record of hominin life indexed advances in hominin cognitive sophistication in a relatively direct way. In particular, the “Upper Paleolithic Transition”—an apparently abrupt increase in the complexity and disparity of our material culture—was thought to signal the arrival of the fully human mind. While the idea of a direct relationship between material complexity and cognitive sophistication still has some defenders, this view has largely been abandoned. It is now (...) widely appreciated that aspects of ancient hominins’ demographic and social organization have a powerful influence both on the material culture they need and the material culture they can sustain. But if this more nuanced view is right, what does the deep material record tell us about the evolution of hominin cognition? I explore that question in this article. (shrink)

Natural myside bias is the tendency to evaluate propositions from within one's own perspective when given no instructions or cues (such as within-participants conditions) to avoid doing so. We defined the participant's perspective as their previously existing status on four variables: their sex, whether they smoked, their alcohol consumption, and the strength of their religious beliefs. Participants then evaluated a contentious but ultimately factual proposition relevant to each of these demographic factors. Myside bias is defined between-participants as the mean difference (...) in the evaluation of the proposition between groups with differing prior status on the variable. Whether an individual difference variable (such as cognitive ability) is related to the magnitude of the myside bias is indicated by whether the individual difference variable interacts with the between-participants status variable. In two experiments involving a total of over 1400 university students ( n = 1484) and eight different comparisons, we found very little evidence that participants of higher cognitive ability displayed less natural myside bias. The degree of myside bias was also relatively independent of individual differences in thinking dispositions. We speculate that ideas from memetic theory and dual-process theory might help to explain why natural myside bias is quite dissociated from individual difference variables. (shrink)

The cognitive critique of the goals and desires that are input into the implicit calculations that result in instrumental rationality is one aspect of what has been termed broad rationality (Elster, 1983). This cognitive critique involves, among other things, the search for rational integration (Nozick, 1993)—that is, consistency between first-order and second-order preferences. Forming a second-order preference involves metarepresentational abilities made possible by mental decoupling operations. However, these decoupling abilities are separable from the motive that initiates the cognitive critique itself. (...) I argue that Velleman (1992) has identified that motive (“the desire to act in accordance with reasons”), and that it might be operationalisable as a thinking disposition at a very superordinate cognitive level. This thinking disposition, the Master Rationality Motive, is likely to be of particular importance in explaining individual differences in the tendency to seek rational integration. Preliminary research on related constructs suggests that this construct is measurable. (shrink)

A recurring claim in a number of behavioural, cognitive and neuro-scientific literatures is that there is, or must be, a unidimensional ‘common currency’ in which the values of different available options are represented. There is striking variety in the quantities or properties that have been proposed as determinants of the ordering in motivational strength. Among those seriously suggested are pain and pleasure, biological fitness, reward and reinforcement, and utility among economists, who have regimented the notion of utility in a variety (...) of ways, some of them incompatible. This topic deserves philosophical attention for at least the following reasons. Repeated invocation of the ‘common currency’ idiom isn’t merely terminological coincidence because most of the claims are competing explanations either of manifest pattern in choices, or of order in the processes producing choice. We can’t suppose that the different currency claims within each area are compatible, because there are significant obstacles to identifying pairs of members of either the ‘pattern’ or ‘process’ group. There are, finally, seriously opposed positions about the relationships between the pattern facts and the process facts. There are philosophical positions both favouring and opposing a common currency. But direct consideration of the abstract relationships between claims about common currencies across scientific settings, and the arguments for and against these claims, is relatively rare. There is, though, much of philosophical interest to be found here. (shrink)

Berkeleyan idealism, or ‘immaterialism,’ has had an enormous impact on the history of philosophy during the last three centuries. In recent years, Christian scholars have been especially active in exploring ways that Berkeley's thesis may be fruitfully applied to a variety of issues in philosophy and theology. This essay provides an overview of some of the ways Christian philosophers have deployed immaterialism to solve problems and generate insights in metaphysics, philosophy of mind, philosophy of science, philosophy of religion, and philosophical (...) theology.

El presente trabajo se propone analizar la posición de Daniel Dennett con respecto a la realidad y naturaleza del yo. El autor considera que la concepción del yo humano propia del sentido común, en tanto que un elemento único, simple, idéntico y continuo, es fundamentalmente una ficción. A partir de este diagnóstico, Dennett se propone ofrecer una explicación de este fenómeno ilusorio desde una doble perspectiva: la heterofenomenología y la memética. La primera y segunda parte de este trabajo estarán destinadas (...) a desarrollar respectivamente estos dos enfoques. En la tercera parte serán analizadas las afirmaciones hechas por el autor dentro de los mencionados marcos teóricos, con el objetivo de mostrar que ambos desarrollos no se complementan entre sí, sino que, por el contrario, presentan ciertas contradicciones a la hora de reconstruir la postura dennettiana global con respecto al yo humano.

In Gray's conjecture, mismatches in the subicular comparator and matches have equal prominence in consciousness. In rival cognitive views novelty and difficulty especially elicit more conscious modes of cognition and higher levels of self-regulation. The mismatch between Gray's conjecture and these views is discussed.

This article argues that Durkheim’s founding insight – uniquely social phenomena – presents us with both a foundation for the discipline of sociology and the risk that the discipline will become isolated. This, we argue, has happened. Our contention is that the emergent social phenomena need to be understood in relation to, but not reduced to, their biological and psychological substrates. Similarly, there are a number of other characteristics, notably of self-organization, which are distinguishing properties of social phenomena but also (...) of quite different phenomena. The comparison is instructive. We therefore argue for an ecological approach to sociological theory, which has important relationships to the general theories and philosophy of ecology and biology. We explore a number of terminological and conceptual parallels that may inform our understanding of the relation of social theory to these and other disciplines. (shrink)

This article contributes to understanding the effect of complexity theory on the social sciences. It analyses the relationships between complex processes of self-organization and the environment or ecology in which these dynamics take place. Two factors are prioritized: the role of information in the formation of complex structure and the development of ‘landscapes’ or topologies of possibility. The authors argue for an ontology that founds both material and informational structures, and for a radical continuity between the general thermodynamics of emergent (...) complex orders, cognitive theory and the complex structures of human thought and culture.

This is not a scholarly research paper, but a ‘position paper’ outlining an approach to the study of mind which has been gradually evolving since about 1969 when I first become acquainted with work in Artificial Intelligence through Max Clowes. I shall try to show why it is more fruitful to construe the mind as a control system than as a computational system.

Robert Cummins [(1996) Representations, targets and attitudes, Cambridge, MA: Bradford/MIT, p. 1] has characterized the vexed problem of mental representation as "the topic in the philosophy of mind for some time now." This remark is something of an understatement. The same topic was central to the famous controversy between Nicolas Malebranche and Antoine Arnauld in the 17th century and remained central to the entire philosophical tradition of "ideas" in the writings of Locke, Berkeley, Hume, Reid and Kant. However, the scholarly, (...) exegetical literature has almost no overlap with that of contemporary cognitive science. I show that the recurrence of certain deep perplexities about the mind is a systematic and pervasive pattern arising not only throughout history, but also in a number of independent domains today such as debates over visual imagery, symbolic systems and others. Such historical and contemporary convergences suggest that the fundamental issues cannot arise essentially from the theoretical guise they take in any particular case. (shrink)

In response to widespread doubts among professional philosophers (Russell, Horwich, Dietrich, McGinn, Chalmers), Stoljar argues for a ‘reasonable optimism’ about progress in philosophy. He defends the large and surprising claim that ‘there is progress on all or reasonably many of the big questions.’ However, Stoljar’s caveats and admitted avoidance of historical evidence permits overlooking persistent controversies in philosophy of mind and cognitive science that are essentially unchanged since the 17th Century. Stoljar suggests that his claims are commonplace in philosophy departments (...) and, indeed, the evidence I adduce constitutes an indictment of the widely shared view among professional analytic philosophers.

If phenomenal consciousness is distinct from the computationally based access-consciousness that controls overt behavior, how can I tell which things (other than myself) enjoy phenomenal consciousness? And if phenomenal consciousness 'plays no role in controlling overt behavior, how do human bodies come to write target articles arguing for the existence of phenomenal consciousness?

This paper takes five different perspectives on kinesthesia, beginning with its evolution across animate life and its biological distinction from, and relationship to proprioception. It proceeds to document the historical derivation of “the muscle sense,” showing in the process how analytic philosophers bypass the import of kinesthesia by way of “enaction,” for example, and by redefinitions of “tactical deception.” The article then gives prominence to a further occlusion of kinesthesia and its subduction by proprioception, these practices being those of well-known (...) phenomenologists, practices that exemplify an adultist perspective supported in large part by the writings of Merleau-Ponty. Following this extended critical review, the article shows how Husserl’s phenomenology enlightens us about kinesthesia and in doing so offers us substantive clues to the phenomenology of learning as it takes place in the development and acquisition of skillful movement. It shows further how phenomenological methodology contrasts markedly with existential analysis, most significantly in its recognition of, and its ability to set forth a developmental history, a veritable genetic phenomenology that is basically a phenomenology of learning anchored in kinesthesia. After showing how that phenomenology of learning finds mutual validation in a classic empirical study of infant movement, the article ends by highlighting how human “I cans” are grounded in “I move,” specifically, in the pan-human ability to learn one’s body and learn to move oneself.
