In this paper I aim to develop a largely non-empirical case for the compatibility of phenomenology and naturalism. To do so, I will criticise what I take to be the standard construal of the relationship between transcendental phenomenology and naturalism, and defend a ‘minimal’ version of phenomenology that is compatible with liberal naturalism in the ontological register and with weak forms of methodological naturalism, the latter of which is understood as advocating ‘results continuity’, over the long haul, with the relevant (...) empirical sciences. Far from such a trajectory amounting to a Faustian pact in which phenomenology sacrifices its soul, I contend that insofar as phenomenologists care about reigning in the excesses of reductive versions of naturalism, the only viable way for this to be done is via the impure and hybrid account of phenomenology I outline here.

Block's P-/A-consciousness distinction rules out P's involving a specific kind of cognitive access and commits him to a “strong” Pconsciousness. This not only confounds plausible research in the area but betrays an anosognosia about Wittgenstein's diagnosis about our philosophical “introspection” of mysterious inner processes.

In this commentary, I point out some weaknesses in Gray's target article and, in the light of that discussion, I attempt to delineate the kinds of problem a cognitive neuroscience of consciousness faces on its way to a scientific understanding of subjective experience.

I criticize Block's examples of P-consciousness and A-consciousness for being flawed and the notion of A-consciousness for not being a notion of consciousness at all. I argue that an empirically important distinction can be made between behavior that is supported by an underlying conscious experience and behavior that is brought about by nonconscious action-control mechanisms. This distinction is different from that made by Block.

Several contemporary philosophical theories of introspection have been offered, yet each faces a number of difficulties in providing an explanation of the exact nature of introspection. I contrast the inner-sense view that argues for a causal awareness with the acquaintance view that argues for a non-causal or direct awareness. After critically examining the inner-sense and the acquaintance views, I claim that these two views are complementary and not mutually exclusive, and that both perspectives, conceived of as modes of introspective access, (...) actually broaden the notion of introspection. I then propose a useful distinction between stimuli-induced introspection—i.e., a receptive process whereby some specific mental states induce introspection—and self-triggered introspection—i.e., a selective process whereby the individual’s own interest and volition initiates introspection. I argue that that distinction may eliminate the false dichotomy which claims that only one of those types of awareness, either the causal one or the direct one, is conducive to introspection or is defined as introspection.

This analysis explores theories of recollective memories and their shortcomings to show how certain recollective memories are to some extent the initial experiencing of past conscious mental states. While dedicated memory theorists over the past century show remembering to be an active and subjective process, they usually make simplistic assumptions regarding the experience that is remembered. Their treatment of experience leaves unexplored the notion that the truth of memory is a dynamic interaction between experience and recollection. The argument's seven sections (...) examine how experience, consciousness, and the self produce memories in odd but actual situations. Examples are presented that are either actual or technologically possible, and they pose a challenge for some theories of memory. Showing that an experience and a memory must be bound by psychological continuity, the sections build upon each other to challenge aprioristic beliefs about the self and consciousness. The later sections examine the lack of available accounts of memory that acknowledge consciousness, dissociation, and "selfhood" to be matters of degree, thus rendering memory theories next to useless when trying to effectively incorporate the notions of experience and reality.

Gray, like other recent authors, seeks a scientific approach to consciousness, but fails to provide a biologically convincing description, partly because he implicitly bases his model on a computationalist foundation that embeds the contents of thought in irreducible symbolic representations. When patterns of neural activity instantiating conscious thought are shorn of homuncular observers, it appears most likely that these patterns and the circuitry that compares them with memories and plans should be found distributed over large regions of neocortex.

Color vision provides accurate measures of the phase and intensity of daylight, and also a means of discriminating between objects. Neither property implies that objects are colored.

Some dichotomies related to modeling electrocortical activities are analyzed. Attractor neural networks versus biologically motivated models, near-equilibrium versus nonequilibrium processes, linear and nonlinear dynamics, stochastic and chaotic patterns, local and global scale simulation of cortical activities are discussed.

I examine the way in which Daniel Dennett (1987, 1995) uses his 'intentional' and 'design' stances to make the claim that intentionality is derived from design. I suggest that Dennett is best understood as attempting to supply an objective, nonintentional, naturalistic rationale for our use of intentional concepts. However, I demonstrate that his overall picture presupposes prior application of the intentional stance in a preconditional, ineliminable,'sense-giving' role. Construed as such, Dennett's account is almost identical to the account of biological teleology (...) offered by Kant in The Critique of Judgement, with the consequence that Dennett's naturalism is untenable. My conclusions lead to doubts concerning the legitimacy of any account attempting to naturalise intentionality by extracting normativity from biology and also point to a novel account of biological function.

The accurate measurement of the level of consciousness of a creature remains a major scientific challenge, nevertheless a number of new accounts that attempt to address this problem have been proposed recently. In this paper we analyze the principles of these new measures of consciousness along with other classical approaches focusing on their applicability to Machine Consciousness (MC). Furthermore, we propose a set of requirements of what we think a suitable measure for MC should be, discussing the associated theoretical and (...) practical issues. Using the proposed requirements as a framework for the design of an integrative measure of consciousness, we explore the possibility of designing such a measure in the context of current state of the art in consciousness studies.

If sensations were behaviorally conceived, as they should be, as complex functional patterns of interaction between overt behavior and the environment, there would be no point in searching for them as instantaneous psychic elements within the brain or as internal products of the brain.

In this article, I develop an account of the use of intentional predicates in cognitive neuroscience explanations. As pointed out by Maxwell Bennett and Peter Hacker, intentional language abounds in neuroscience theories. According to Bennett and Hacker, the subpersonal use of intentional predicates results in conceptual confusion. I argue against this overly strong conclusion by evaluating the contested language use in light of its explanatory function. By employing conceptual resources from the contemporary philosophy of science, I show that although the (...) use of intentional predicates in mechanistic explanations sometimes leads to explanatorily inert claims, intentional predicates can also successfully feature in mechanistic explanations as tools for the functional analysis of the explanandum phenomenon. Despite the similarities between my account and Daniel Dennett's intentional-stance approach, I argue that intentional stance should not be understood as a theory of subpersonal causal explanation, and therefore cannot be used to assess the explanatory role of intentional predicates in neuroscience. Finally, I outline a general strategy for answering the question of what kind of language can be employed in mechanistic explanations. (shrink)

What is a person, and how can a person come to know that she is a person identical to herself over time ? The article defends the view that the sense of being oneself in this sense consists in the ability to consciously affect oneself : in the memory of having affected oneself, joint to the consciousness of being able to affect oneself again. In other words, being a self requires a capacity for metacognition (control and monitoring of one's own (...) internal states). This view is compatible with the hypothesis that the self is a dynamic representation emerging out of a higher level control system, - valuation control - whose articulation with control of plans and perceptual/motor control is discussed in the context of normal and pertrubed agency.

Intentionalism is the view that the phenomenal character of a conscious experience is wholly determined by, or even reducible to, its representational content. In this essay I put forward a version of intentionalism that allows (though does not require) the reduction of phenomenal character to representational content. Unlike other reductionist theories, however, it does not require the acceptance of phenomenal externalism (the view that phenomenal character does not supervene on the internal state of the subject). According the view offered here, (...) phenomenal characters essentially represent subject-environment relations that are relevant to the possibilities for causal interaction between the subject and the environment; relations of the kind that J. J. Gibson dubbed affordances. I argue for this view chiefly through an examination of spatial perception, though other cases are also considered. The view assumes that a phenomenal character has an essential functional role; though it need not be assumed that a functional role is sufficient for a phenomenal character. (shrink)

Wright & Liley contrast their theory that the global dynamics of the EEG are linear with that of Freeman, who hypothesizes an EEG governed by (nonlinear) deterministic-chaotic dynamics. A “call for further discussion” on the part of the authors is made as to how either theory fits with experimental findings indicating that EEG dynamics are non-linear but stochastic.

The nature of the relationship between mind and body is one of the greatest remaining mysteries. As such, the historical origin of the current dominant belief that mind is a function of the brain takes on especial significance. In this article I aim to explore and explain how and why this belief emerged in early 19th-century Britain. Between 1815 and 1819 two brain-based physiologies of mind were the subject of controversy and debate in Britain: the system of phrenology devised by (...) Franz Joseph Gall, and William Lawrence’s lectures at the Royal College of Surgeons. Both owed a profound intellectual debt to continental comparative anatomy. In the final quarter of the 18th-century, Johann Friedrich Blumenbach, Petrus Camper and Johann Gottfried von Herder had broken away from the traditional doctrine of the Great Chain of Being by allowing for a clear anatomical distinction between ‘man’ and beast based on the morphology of the skull. This reconceptualization of man as an anatomically distinct being gave Gall and Lawrence grounds to propose that the peculiarities of the human mind were dependent on mankind’s unique cerebral size and structure.

For some years there has been a controversy about whether brain state variables such as EEG or neuronal spike trains exhibit chaotic behaviour. Wright & Liley claim that the local dynamics measured by spike trains or local field potentials exhibit chaotic behaviour, but global measures like EEG should be governed by linear dynamics. We propose a different scheme. Based on simulation studies and various experiments, we suggest that the pointwise dimension of EEG time series may provide some valuable information about (...) underlying neuronal generators.

There is a tendency in both scientific and humanistic disciplines to think of biological evolution in humans as significantly impeded if not completely overwhelmed by the robust cultural and technological capabilities of the species. The aim of this article is to make sense of and evaluate this claim. In Section 2 , I flesh out the argument that humans are ‘insulated’ from ordinary evolutionary mechanisms in terms of our contemporary biological understandings of phenotypic plasticity, niche construction, and cultural transmission. In (...) Section 3 , I consider two obvious objections to the above argument based on the growing literatures related to gene-culture coevolution and recent positive selection on the human genome, as well as a pair of less common objections relating to the connection between plasticity, population size and evolvability. In Section 4 , I argue that both the ‘human evolutionary stasis argument’ and its various detractor theories are premised on a fundamental conceptual flaw: they take evolutionary stasis for granted, since they fail to conceive of stabilizing selection as a type of evolution and drift as a universal tendency that dominates in the absence of selection. Without the continued operation of natural selection, the very properties that are purported to reduce the evolutionary response to selection in humans would themselves drift into non-functionality. I conclude that properly conceived, biological evolution is a permanent and ineradicable fixture of any species, including Homo sapiens. (shrink)

The meaning and significance of Benjamin Libet’s studies on the timing of conscious will have been widely discussed, especially by those wishing to draw sceptical conclusions about conscious agency and free will. However, certain important correctives for thinking about mental states and processes undermine the apparent simplicity and logic of Libet’s data. The appropriateness, relevance and ecological validity of Libet’s methods are further undermined by considerations of how we ought to characterise intentional actions, conscious intention, and what it means to (...) act with conscious intent. Recent extensions of Libet’s paradigm using fMRI and decision-based tasks suffer from similar limitations. The result is that these sorts of laboratory studies of isolated, trivial, decontextualized bodily movements, in a context of extended (conscious) intentional experimental participation and cooperation, are of dubious and potentially misleading relevance to the study of agency.

This article presents and analyses a social-practice contextualist version of meaning holism, whose main root lies in American pragmatism. Proposing that beliefs depend on systems of language-use in social practices, which involve communities of people and worldly objects, such meaning holism effectively breaks down the Enlightenment tradition’s philosophical subject–object dualism. It also opens the human mind up for empirical research – in a ‘sociologizing’, ‘anthropologizing’ and ‘historicizing’ vein. The article discusses the implications of this approach for the human sciences, for (...) instance certain parallel developments in anthropology and archaeology. (shrink)

Epistemic divergence occurs when different investigators give different answers to the same question using evidence-collecting methods that are not public. Without following the principle that scientific methods must be public, scientific communities risk epistemic divergence. I explicate the notion of public method and argue that, to avoid the risk of epistemic divergence, scientific communities should (and do) apply only methods that are public.

Philosophers have long struggled to understand our perceptual experience of temporal properties such as succession, persistence and change. Indeed, strikingly, a number have felt compelled to deny that we enjoy such experience. Philosophical puzzlement arises as a consequence of assuming that, if one experiences succession or temporal structure at all, then one experiences it at a moment. The two leading types of theory of temporal awareness—specious present theories and memory theories—are best understood as attempts to explain how temporal awareness is (...) possible within the constraints of this principle. I argue that the principle is false. Neither theory of temporal awareness can be made workable unless it is rejected. Our experience of temporal phenomena cannot be understood if we attempt to break experience down into instantaneous slices. In order to understand the perception of temporal properties we must look beyond the instant. (shrink)
