In this paper we try to diagnose one reason why the debate regarding the Hard Problem of consciousness inevitably leads to a stalemate: namely that the characterisation of consciousness assumed by the Hard Problem is unjustified and probably unjustifiable. Following Dennett : 4–6, 1996, Cognition 79:221–237, 2001, J Conscious Stud 19:86, 2012) and Churchland :402–408, 1996, Brainwise: studies in neurophilosophy. MIT Press, Cambridge, MA, 2002), we argue that there is in fact no non-question begging argument for the claim that consciousness (...) is a uniquely Hard Phenomenon. That is; there is no non-question begging argument for the claim that consciousness is necessarily in explicable in terms of the structure and function of mental states. Unfortunately the debate has not moved on because the majority of materialists feel the pull of the at least one of, what we call, the ‘key’ intuitions that supposedly support dualism and the existence of a Hard Phenomenon and so try to accommodate them rather than denying them. Although this a possible response to the intuitions it tends to mask the fact that there is in fact no argument for the existence of a Hard Phenomenon. So we end up participating in our own hornswoggling :402–408, 1996) and chasing our tails trying to answer a question we should in fact ignore. We have no reason to think there is a Hard Problem of consciousness because we have no reason to think the Hard Phenomenon exists. (shrink)

This paper examines the possibility of finding evidence that phenomenal consciousness is independent of access. The suggestion reviewed is that we should look for isomorphisms between phenomenal and neural activation spaces. It is argued that the fact that phenomenal spaces are mapped via verbal report is no problem for this methodology. The fact that activation and phenomenal space are mapped via different means does not mean that they cannot be identified. The paper finishes by examining how data addressing this theoretical (...) question could be obtained. (shrink)

Recently a number of authors have responded to the knowl-edge argument by suggesting that Mary could learn about new physi-cal facts upon release (Flanagan, 1992; Mandik, 2001; Stoljar, 2001; Van Gulick, 1985). A key step in achieving this is a demonstration that there are facts that can be known via colour experience that cannot be learnt scientifically. In this paper I develop an account of scientific and visual knowledge on which there is a difference between the knowledge provided by science (...) and that provided by vision. (shrink)

If Australasian philosophers constitute the kind of group to which a collective identity or broadly shared self-image can plausibly be ascribed, the celebrated history of Australian materialism rightly lies close to its heart. Jack Smart’s chapter in this volume, along with an outstanding series of briefer essays in A Companion to Philosophy in Australia and New Zealand (Forrest 2010; Gold 2010; Koksvik 2010; Lycan 2010; Matthews 2010; Nagasawa 2010; Opie 2010; Stoljar 2010a), effectively describe the naturalistic realism of Australian philosophy (...) of mind. In occasional semi-serious psychogeographic speculation, this long-standing and strongly-felt intellectual attitude has been traced back to the influences of our light, land, or lifestyle (Devitt 1996, x; compare comments by Chalmers and O’Brien in Mitchell, 2006). Australasian work in philosophy of mind and cognition has become more diverse in the last 40 years, but is almost all still marked, in one way or another, by the history of these debates on materialism.

Despite a wealth of data we still have no clear idea what color experiences represent. In fact, color experiences vary with so many factors that it has been claimed that they do not represent anything at all. The primary challenge for any representational account of color experience is to accommodate the various psychophysical results that demonstrate that color appearance depends not only on the spectral nature of the target but also on the spectral, spatial and figural nature of the surround. (...) A number of theorists have proposed that this dependence is an aspect of the visual system's constancy mechanism. However this does not in and of itself tell us what, if anything, is represented in color experience. Ultimately the answer to this question will be informed by one's theory of representational content. I will argue that adopting a molecular scheme of representation enables the development of an account of the represented object of color experience that can do justice to the psychophysical data.

Objective To review the way consciousness is operationalised in contemporary research, discuss strengths and weaknesses of current approaches and propose new measures. Method We first reviewed the literature pertaining to the phenomenal character of visual and self-consciousness as well as awareness of visual stimuli. We also reviewed more problematic cases of dreams and animal consciousness, specifically that of octopuses. Results Despite controversies, work in visual and self consciousness is highly developed and there are notable successes. Cases where experiences are not (...) induced, such as dreams, and where no verbal report is possible, such as when we study purported experiences of octopuses, are more challenging. It is difficult to be confident about the reliability and validity of operationalisations of dreams. Although this is a general concern about the measuring consciousness, it is not a sufficiently severe concern to completely undermine the work reviewed on vision and self-consciousness. It is more difficult to see how the good work on human psychology can be applied to non-human animals, especially those with radically different nervous systems, such as octopuses. Given the limitations of report-based operationalisations of consciousness, it is desirable to develop non-report-based measures, particularly for phenomenal qualities. We examine a number of possibilities and offer two possible approaches of varying degrees of practicality, the first based on combining quality space descriptions of phenomenal qualities and the notion of a “neural activation space” inherited from connectionist A.I., the second being a novel match to target approach Conclusion Consciousness is a multifacted phenomenon and requires a variety of operationalisations to be studied.

Proponents of the hard problem of consciousness argue that the zombie and inverted spectrum thought experiments demonstrate that consciousness cannot be physical. They present scenarios designed to demonstrate that it is conceivable that a physical replica of someone can have radically different or no conscious experiences, that such an experience-less replica is possible and therefore that materialism is false. I will argue that once one understands the limitations that the physics of this world puts on cognitive systems, zombies and the (...) inverted spectrum are not conceivable. (shrink)

Kim (1998) has argued that a genuine robust physicalism does not leave any room for real, causally efficacious mental properties. Despite all of his concerns about the reality and causal efficacy of mental phenomena Kim does not eliminate all higher-level macro causation. Kim’s problem with the mental is that most current cognitive theories imply that the mind is not higher-level but higher-order. In this paper I argue that connectionism makes meaning higher-level and therefore by Kim’s own standards puts meaning on (...) the same footing as other real causally efficacious higher-level properties. The upshot is that we can side-step the current debate about mental causation by moving the mind to the shared uncontroversially real and physical common-ground. (shrink)

The goal of the symposium 'Integrating Perspectives on the Relation between Mind and Brain' was to get people with different views and from different disciplines to open up a dialogue by focusing on answering a set of questions. In this paper I present a view of the relation between the mind and the brain that is informed by recent work in the philosophy of science. The basic idea is that the mind is more than the brain because mental states are (...) identical to the activity of groups of organized neurons. Unlike the standard non-reductive materialism irreducibility is not seen as related to multiple realisability. The upshot is that we can bring the relation between the mind and the brain in line with other clear cases of ontological emergence, we can see how psychology can be an independent science, and yet how important explanatory connections can be made between psychology and neuroscience.
