One of the main dividing lines within the debate on the problem of consciousness comes between representationalist separatism and phenomenalist inseparatism. According to the former, representational mental states are possible in the absence of phenomenal consciousness, and furthermore, an adequate naturalistic theory of representation is necessary and sufficient for the explanation of phenomenal consciousness. According to the later, phenomenal consciousness is necessary for the existence and the explanation of any representational state and, indeed, of any mental state. Several arguments have (...) tried to offer support to this inseparatist thesis. Those proposed by Galen Strawson and John Searle summarize this kind of argument, which is based on the introduction of implicit premises. In addition to this failure, inseparatism faces the problems of its empirical inoperativeness and inadequacy, as well as its lack of phylogenetic verisimilitude. (shrink)

Responsible Research and Innovation (RRI) is an important ethical, legal, and political theme for the European Commission. Although variously defined, it is generally understood as an interactive process that engages social actors, researchers, and innovators who must be mutually responsive and work towards the ethical permissibility of the relevant research and its products. The framework of RRI calls for contextually addressing not just research and innovation impact but also the background research process, specially the societal visions underlying it and the (...) norms and priorities that shape scientific agendas. This requires the integration of anticipatory, inclusive, and responsive dimensions, and the nurturing of a certain type of reflexivity among a variety of stakeholders, from scientists to funders. In this paper, we do not address potential limitations but focus on the potential contribution of philosophical reflection to RRI in the context of the Ethics and Society subproject of the Human Brain Project (HBP). We show how the type of conceptual analysis provided by philosophically oriented approaches theoretically and ethically broadens research and innovation within the HBP. We further suggest that overt inclusion of philosophical reflection can promote the aims and objectives of RRI. (shrink)

The idea to utilise cognitive neuroscientific research for educational purposes is known as Mind-Brain Education or Educational Neuroscience. Despite some calls for an uncritical endorsement of such an agenda, a growing number of educational scholars argue that it must remain impossible to translate neurological descriptions into mental or educationally relevant descriptions. This paper takes these well-established arguments further by not only focusing upon these different levels of description but going beyond this issue to assess the theoretical foundations of cognitive science (...) as a functional theory of the mind. With relevance to education it is argued that because of its functional character a cognitive-psychological approach to education suffers from an inherent blind spot regarding the actor’s feelings and motivations. The paper concludes with the claim that, because of this experiential poverty, any cognitive neuroscientific approach must face severe limitations when utilised for educational purposes. (shrink)

In this essay we argue that the notion of machine necessarily includes its being designed for a purpose. Therefore, being a mechanical system is not enough for being a machine. Since the experimental scientific method excludes any consideration of finality on methodological grounds, it is then also insufficient to fully understand what machines are. Instead in order to understand a machine it is first required to understand its purpose, along with its structure, in clear parallel with Aristotle’s final and formal (...) causes. Obviously, purpose and structure are not machine components that can physically interact with other components; nonetheless they are essential to understanding their operation. This casts an interesting light on the relationship between mind and body: for just as an artifact’s finality and structure explain its operation, so also consciousness is the explanation—not the efficient cause—of specifically human behavior. What machines and human beings have in common is that, in order to understand them, it is necessary to appeal to the principle of finality. Yet while finality is given and extrinsic in the case of machines, we human beings are characterized by the ability to self-propose our own ends. Since the principle of finality is essential to understanding the production of machines, the traditional view in modern Western philosophy that finality lies beyond the scope of objective/scientific knowledge should be rectified to allow for a genuine science of the artificial. We think a correct understanding of final causality will overcome current resistance to this principle. (shrink)

Barry Allen, in his 2005 Knowledge and Civilization and his 2008 Artifice and Design, argues in favor of an epistemic system that is both praxical and performative; knowledge, rather than being expressed propositionally, is a kind of performance that is expressed in artifacts of all kinds, of which propositions are but an example. However, although he makes a compelling case, it is rather less clear the extent to which we are able to make judgments about the world beneath the artifacts. (...) That is to say: it seems clear that we need to provide some account of how the world is, if only so that we have some kind of coherent characterization of what it is exactly that an artifact captures. Accordingly, if we are to buy into Allen’s model, what can we subsequently say about Allen’s metaphysics? This paper is an attempt to tease out some of these concerns. (shrink)

Weak emergence has been offered as an explication of the ubiquitous notion of emergence used m complexity science After outlining the problem of emergence and comparing weak emergence with the two other weak objectivist approaches to emergence, the paper explains a version of weak emergence and illustrates at with cellular automata Then it explains the sort of downward causation and explanatory autonomy involved m weak emergence.

A glass couldn't contain water unless it contained H2O-molecules. Likewise, a man couldn't be a bachelor unless he was unmarried. Now, the latter is what we would call a conceptual or analytical truth. It's also what we would call a priori. But it's hardly a conceptual or analytical truth that if a glass contains water, then it contains H2O-molecules. Neither is it a priori. The fact that water is composed of H2O-molecules was an empirical discovery made in the eighteenth century. (...) The fact that all bachelors are unmarried was not. But neither is a logical truth, so how do we explain the difference? Two-dimensional semantics is a framework that promises to shed light on these issues. The main purpose of this thesis is to understand and evaluate this framework in relation to various alternatives, to see whether some version of it can be defended. I argue that it fares better than the alternatives. However, much criticism of two-dimensionalism has focused on its alleged inability to provide a proper semantics for certain epistemic operators, in particular the belief operator and the a priori operator. In response to this criticism, a two-dimensional semantics for belief ascriptions is developed using structured propositions. In connection with this, a number of other issues in the semantics of belief ascriptions are addressed, concerning indexicals, beliefs de se, beliefs de re, and the problem of logical omniscience.

In this article, I present a novel approach to the scientific understanding of consciousness. It is based on the hypothesis that the full range of phenomenal qualities is built into the frequency spectrum of a ubiquitous background field and proceeds on the assumption that conscious systems employ a universal mechanism by means of which they are able to extract phenomenal nuances selectively from this field. I set forth that in the form of the zero-point field (ZPF) physics can offer a (...) promising candidate that is qualified for playing the dual role as both the carrier of energy and consciousness. The appropriate mechanism, which rests upon the principle of dynamical coupling of ZPF modes, is a unique feature of quantum systems, suggesting that the dividing line between conscious and non-conscious systems is defined by the differentiation between quantum systems and classical systems. The presence of this mechanism in the brain is supported by the neurophysiological body of evidence, leading to a consistent explanation of the dynamical properties of the neural correlates of consciousness. Building on these findings, I lay the foundations for the conceptually coherent integration of consciousness into the physical worldview, derive an indicator for the quantity of consciousness of a given system, and outline the further steps toward a theory of consciousness.

Reduction and reductionism have been central philosophical topics in analytic philosophy of science for more than six decades. Together they encompass a diversity of issues from metaphysics and epistemology. This article provides an introduction to the topic that illuminates how contemporary epistemological discussions took their shape historically and limns the contours of concrete cases of reduction in specific natural sciences. The unity of science and the impulse to accomplish compositional reduction in accord with a layer-cake vision of the sciences, the (...) seminal contributions of Ernest Nagel on theory reduction and how they strongly conditioned subsequent philosophical discussions, and the detailed issues pertaining to different accounts of reduction that arise in both physical and biological science (e.g., limit-case and part-whole reduction in physics, the difference-making principle in genetics, and mechanisms in molecular biology) are explored. The conclusion argues that the epistemological heterogeneity and patchwork organization of the natural sciences encourages a pluralist stance about reduction. (shrink)

This paper argues that emergent conscious properties can't bestow emergent causal powers. It supports this conclusion by way of a dilemma. Necessarily, an emergent conscious property brings about its effects actively or other than actively. If actively, then, the paper argues, the emergent conscious property can't have causal powers at all. And if other than actively, then, the paper argues, the emergentist finds himself committed to incompatible accounts of causation.

We tend to think that our concepts are stable in the sense that, whilst their extensions may vary across distinct epistemic scenarios, the reference-fixing conditions by which we discover these extensions remain fixed. This paper challenges this orthodoxy. In particular, it aims to motivate the position that some concepts are unstable in that their reference-fixing conditions themselves vary across distinct epistemic scenarios. Furthermore, it aims to draw out the implications such instability has for epistemic possibility and apriority. I shall argue (...) that when unstable concepts are concerned epistemic space will be widened, which in turn will restrict our a priori knowledge; and in ways that might be salient to solving certain familiar philosophical problems.

Jeffrey Gray’s Consciousness: Creeping up on the Hard Problem will be enjoyed by everyone interested in consciousness. Gray, a neuropsychologist, eloquently summarizes significant experimental results on consciousness and, more importantly, explains both how these results interrelate and how they constrain potential theories of consciousness. He also uses these results to build a novel, fascinating theory of what consciousness does and does not do. Throughout the work Gray’s accessible presentation remains deeply respectful of psychologists, neuroscientists, and philosophers’ approaches to consciousness. In (...) this respect, Gray’s book is an ideal work for an interdisciplinary audience. Sadly, Gray died three months before the publication of this excellent work. (shrink)

Attempts to elucidate the kinds of “thing” or “things” to which the term shamanic journeying image is referentially linked must grapple with two related questions: what is the fundamental nature of shamanic journeying images, and how might the origin of a shamanic journeying image be found? The first question is ontological, concerned with the nature and essence of shamanic journeying images. In contrast, the second is epistemological and methodolgical, concerned with how to acquire knowledge of shamanic journeying images. We demonstrate (...) how inductive and deductive reasoning, the private language argument, and reification render problematic the resolution of both. Finally, we present a method to preliminarily formulate an ontology and epistemology of shamanic journeying imagery. (shrink)

Many debates about consciousness appear to be endless, in part because of conceptual confusions preventing clarity as to what the issues are and what does or does not count as evidence. This makes it hard to decide what should go into a machine if it is to be described as 'conscious'. Thus, triumphant demonstrations by some AI developers may be regarded by others as proving nothing of interest because the system does not satisfy *their* definitions or requirements specifications.

In an earlier paper (Biggs, 2007) I argue that those attributing mental states sometimes simulate the phenomenal states of those to whom they are making attributions (i.e., targets). In this paper I argue that such phenomenal simulation plays an important role in some third-person mental state attributions. More specifically, I identity three important roles that phenomenal simulation could play in third-person mental state attributions: phenomenal simulation could cause attributions, facilitate attributions, or deepen simulators' understanding of targets. I then argue that (...) phenomenal simulation sometimes deepens simulators' understanding of targets, regardless of whether it causes or facilitates any attributions. Accordingly, I conclude that phenomenal simulation plays an important role some third-person mental state attributions. I close by briefly considering how this conclusion relates to the theory-theory versus simulation-theory debate. (shrink)

Zombies make trouble for physicalism. Intuitively, they seem conceivable, and many take this to support their metaphysical possibility – a result that, most agree, would refute physicalism. John Hawthorne (2002) [Philosophical Studies 109, 17–52] and David Braddon-Mitchell (2003) [The Journal of Philosophy 100, 111–135] have developed a novel response to this argument: phenomenal concepts have a conditional structure – they refer to non-physical states if such states exist and otherwise to physical states – and this explains the zombie intuition. I (...) argue that this strategy fails. The considerations Hawthorne and Braddon-Mitchell adduce in support of their analysis in fact do no such thing. Further, their main argument for the analysis is self-defeating: exactly similar reasoning would undermine the view it is meant to establish. Finally, on closer inspection the conditional analysis is incompatible with the zombie intuition. Thus, not only is the analysis incapable of explaining the intuition: the intuition’s plausibility indicates that the analysis is incorrect. I also suggest that the allure of the conditional-analysis strategy may derive from a questionable view about what explaining the intuition would require. (shrink)

Rosenberg does not provide arguments for some crucial premises in his argument against physicalism. In particular, he gives no independent argument to show that physicalists must accept the entry-by-entailment thesis. The arguments provided establish weaker premises than those that are needed. As a consequence, Rosenberg.

Boghossian argued that externalism is incompatible with a transparency thesis according to which we can know a priori whether any two of our occurrent thoughts have the same or distinct content, and that this transparency thesis is integral to our commonsense conception of rationality, which requires the apriority of our logical abilities. Stalnaker offered a detailed compatibilist response to Boghossian. Boghossian criticized this response, and Stalnaker replied. But the outcome of that important discussion remained unclear, partly because it was unclear (...) how to understand the amended transparency thesis at which Stalnaker was gesturing. My aim in this paper is to settle the matter. I wish to clarify the terms of the debate, also by highlighting the relevant commitments of Stalnaker’s two-dimensionalist account, and to show that his compatibilist response, which appeals to diagonal propositions, is unsuccessful.

This thesis contextualises academic writing in EAP (English for Academic Purposes) and subjects it to an interdisciplinary (educational and philosophical) analysis in order to argue that what makes writing academic are its socio-academic practices and values, not its conventional forms. In rejecting dominant discourses that frame academic writing as a transferable skill which can be reduced to conventional forms, I show that academic writings are varied and evolve alongside changing writer agencies and textual environments. This accounts for the emergence of (...) a diverse academic writing landscape that enacts diverse socio-academic practices and that does not reduce writing to predictable static surface features. My methodology resists traditional disciplinary classifications and is in line with the reflective and interpretative approaches associated with the humanities. Rather than ‘filling a gap’ in academic writing research, I challenge writing conventions in EAP by questioning assumptions. This is because EAP is influential in shaping discourses about academic writing and, as such, it must not mislead students and practitioners about the evolving purposes, forms and possibilities for academic expression. The thesis is divided into three parts, each containing two chapters. Part 1 is concerned with explaining what academic writing is in EAP and how EAP can misrepresent it. Part 2 delves into the history of writing and literacy to tease out the ideologies shaping writing practices. Part 3 proposes a model based on philosophical theories of mind and sociology that lays the foundation for a macro theory of academic writing and a future writing pedagogy. The model re-imagines academic writing as an affordance within a non-linear, emergent and complex social open system. This system can be referred to as an organic unity and requires a shift from conceiving writing as a ‘transferable skill’. When re-imagined as an affordance, change and diversity in academic writing practices become possible. (shrink)

Mental causation is vitally important to the integrated information theory (IIT), which says consciousness exists since it is causally efficacious. While it might not be directly apparent, metaphysical commitments have consequential entailments concerning the causal efficacy of consciousness. Commitments regarding the ontology of consciousness and the nature of causation determine which problem(s) a view of consciousness faces with respect to mental causation. Analysis of mental causation in contemporary philosophy of mind has brought several problems to the fore: the alleged lack (...) of psychophysical laws, the causal exclusion problem, and the causal pairing problem. This article surveys the threat each problem poses to IIT based on the different metaphysical commitments IIT theorists might make. Distinctions are made between what I call reductive IIT, non-reductive IIT, and non-physicalist IIT, each of which make differing metaphysical commitments regarding the ontology of consciousness and nature of causation. Subsequently, each problem pertaining to mental causation is presented and its threat, or lack thereof, to each version of IIT is considered. While the lack of psychophysical laws appears unthreatening for all versions, reductive IIT and non-reductive IIT are seriously threatened by the exclusion problem, and it is difficult to see how they could overcome it while maintaining a commitment to the causal closure principle. Yet, non-physicalist IIT denies the principle but is therefore threatened by the pairing problem, to which I have elsewhere provided a response that is briefly outlined here. This problem also threatens non-reductive IIT, but unlike non-physicalist IIT it lacks an evident response. The ultimate aim of this survey is to provide a roadmap for IIT theorists through the maze of mental causation, by clarifying which commitments lead to which problems, and how they might or might not be overcome. Such a survey can aid IIT theorists as they further develop and hone the metaphysical commitments of IIT. (shrink)

Jaegwon Kim maintains that his ‘exclusion argument’ forces us to accept reductive physicalism, which identifies mental and other high-level properties of the world with lower-level properties, over nonreductive physicalism, which avoids such identifications. According to Kim, the exclusion argument shows that any nonreductive view leads to either epiphenomenalism or unacceptable overdetermination of physical effects by physical causes. However, a popular nonreductive physicalist approach called ‘compatibilism’ aims to show that physicalism need not collapse high-level properties into lower-level physical. Compatibilism attempts to (...) block the exclusion argument by attending to the tight modal relationship between higher and lower properties required by nonreductive physicalism. Unfortunately, a similarly tight modal relationship will be embraced by any dualists who hold that natural laws are metaphysically necessary. Despite its increasingly widespread popularity among nonreductive physicalists, it thus seems that the compatibilist’s proposed solution cannot be upheld without removing the barriers to dualists of this sort.

I look at some central positions in the mental causation debate – reductionism, emergentism, and nonreductive physicalism – on the hypothesis that mental causation is intelligible. On this hypothesis, mental causes and their effects are internally related so that they intelligibly “fit”, analogous to the way puzzle pieces interlock, or shades of red fall into order within a color sphere. The assumption of intelligibility has what I take to be a welcome consequence: deciding among rivals in the mental causation debate (...) could end up to be largely an empirical matter. (shrink)

The enactive approach to cognition and consciousness offers a valuable alternative to the standard approaches dominant in the sciences of mind. As an embodied account, enactivism incorporates theoretical perspectives on the body from phenomenology, cognitive science, and biology, which provides a unique interpretation of embodiment with critical insight into the embodied nature of cognition and consciousness. Nonetheless, I argue that several revisions are required to make enactivism viable within the context of the sciences of mind. The enactive account of subjectivity (...) is problematic, in light of arguments developed in Maurice Merleau-Ponty’s later texts, because it is implicitly dualistic. I demonstrate that this implicit dualism can be resolved by incorporating the conceptual framework of flesh that Merleau-Ponty introduces in his later works. However, this new framework presents a challenge of understanding how body can break with world in experience. I provide a solution to this problem by way of developing revisions to the enactive account of cognition, which I argue is problematic in its generality. I offer a new interpretation of enactive cognition modelled on structural flexibility that overcomes the difficulties of the previous account. These revisions to enactive cognition provide a way of understanding how body can break with world, resulting in an account of the enactive body as expressing a massive integration of its different ways of being in the world, as cognitive, conscious, affective, and agentive. These revisions provide a more consistent and plausible articulation of the enactive approach that is more amenable to guiding the sciences of mind. (shrink)

This is not surprising, given that vision holds for us a certain prestige. Our visual experience is incredibly rich, offering up a mosaic (...) of apparent three-dimensional objects. For this reason, it is commonplace to suppose that visual experience is world-directed, with the view taking its most popular form in the representational, or content, view. World-directed views contrast with what we might call subjectivist views — views according to which experiences are raw feels or mere sensations. (shrink)

Jaegwon Kim’s (2005) most recent formulation of the so-called Supervenience Argument against Non-Reductive Physicalism is discussed. The two stages of Kim’s argument can be seen as instances of, what I will call, the Generalized Exclusion Argument.

There is a tension or even contradiction between mental causation - the belief that some mental events or properties are causally relevant for some physical events or properties - and the irreducibility of mental features to physical ones, the causal closure of the physical, and the assumption that there is no overdetermination of the physical. To reconcile these premises was a promise of nonreductive physicalism, but a closer inspection shows that it is, on the contrary, a source of the problem (...) - namely, the unintelligibility of mental causation. This has to do with the widely-held assumption that the mental supervenes on the physical. How can the mental be causally relevant, then? And what is the relationship of the mental and the physical? There are many options, including identity, realizationism, emergence, or some kind of reducibility. But they all have their own problems, e.g. they threaten mental reality, the causal closure of the physical, or scientific explanations. All these aspects are covered in Jaegwon Kim's book Mind in a Physical World. This paper is a detailed introduction to it, discussing and critically commenting it and those still intriguing, but also confusing and complicated issues of the mind-body problem, especially the ontology of mental causation.

Recent advances in our understanding of complex dynamical systems may be of interest to philosophers seeking the best metaphysical grounds for understanding the qualitative character of subjective experience (qualia). In this thesis I will propose that qualia are not specifically brain processes, but are instead best thought of as world processes that can be characterized as distributed self-organizing networks of Whiteheadian actual entities. On this Whiteheadian model, different aspects of a quale that a subject experiences as a specific shade of (...) blue, might be contributed by entities that are, contemporaneously, also contributing other aspects of other qualia to other subjects widely distributed throughout time and space. Cellular automata and network models will be used to help clarify this proposal. (shrink)

My focus here is on what Hegel has to say about nature and natural kinds, in ‘Observing Reason’ from the Phenomenology, and also in similar material from the Logic and Encyclopedia. I intend to argue that this material suggests a surprising way of stepping beyond the fundamental debate. There can of course be no question of elaborating and defending here a complete interpretation of Hegel’s entire theoretical philosophy. I will have to restrict myself to arguing for the unlikely conclusion that (...) there is an approach that can combine and integrate the strongest points made by both sides in the most basic debate shaping recent Hegel interpretation. What needs explaining is how there could be any single coherent position that in any philosophical sense both cancels and preserves metaphysics. (shrink)

The explosive growth over the last two decades of neuroscience, cognitive science, and “consciousness studies” as generally conceived, remains as yet unaccompanied by a corresponding development in the establishment of an explicitly semiotic understanding of how the relations of sign exchange at the neuronal level function in the larger network of psychologically accessible sign exchange. This article attempts a preliminary foray into the establishment of just such a neurosemiotic. It takes, as its test case and as its point of departure, (...) recent discoveries from the neurobiological research on viuso-motor transformations and on the widespread cortical phenomena of selectively tuned, single-neuron response to argue for a vision of “intersubjectivity” whereby the ens rationis arising as a function of the neuronal semiosphere may be abstracted, constructed, and shared mutually across agents.

Antihaecceitists believe that all facts about specific individuals—such as the fact that Fred exists, or that Katie is tall—globally supervene on purely qualitative facts. Haecceitists deny that. The issue is not only of interest in itself, but receives additional importance from its intimate connection to the question of whether all fundamental facts are qualitative or whether they include facts about which specific individuals there are and how qualitative properties and relations are distributed over them. Those who think that all fundamental (...) facts are qualitative are arguably committed to antihaecceitism. The goal of this paper is to point out some problems for antihaecceitism (and therefore for the thesis that all fundamental facts are qualitative). The article focuses on two common assumptions about possible worlds: (i) Sets of possible worlds are the bearers of objective physical chance. (ii) Counterfactual conditionals can be defined by appeal to a relation of closeness between possible worlds. The essay tries to show that absurd consequences ensue if either of these assumptions is combined with antihaecceitism. Then it considers a natural response by the antihaecceitist, which is to deny that worlds play the role described in (i) and (ii). Instead, the reply continues, we can introduce a new set of entities that are defined in terms of worlds and that behave the way worlds do on the haecceitist position. That allows the antihaecceitist to formulate antihaecceitist friendly versions of (i) and (ii) by replacing the appeal to possible worlds with reference to the newly introduced entities. This maneuver invites an obvious reply, however. If the new entities are the things that play the role we typically associate with worlds, as partially described by (i) and (ii), then it is natural to conclude that they really are the entities we talk about when we speak of worlds, so that haecceitism is true after all.

The paper responds to criticisms of *Ignorance and Imagination* offered by Torin Alter and Karen Bennett.

A recent issue of Time magazine (March 29, 1999) was devoted to the twenty greatest "thinkers" of the twentieth century -- scientists, inventors, and engineers. There is one interesting omission: there are no cognitive psychologists or cognitive scientists. (Cognitive science is an amalgam of cognitive, neuro, and developmental psychology, artificial intelligence, philosophy, linguistics, biology, and anthropology.) Freud is there, to be sure. But, while he was very influential, it is not even clear that he was a scientist, let alone a (...) cognitive scientist. There are those who regard Freud as somewhere between incompetent and a charlatan (see Glymour, 1988). In any case, though Freud's positive proposal for the mind's architecture -- namely, that it contains the unconscious -- seems correct as far as it goes, it does appear that all the details are wrong. For example: (1) there is a lot more to the mind than the mere unconscious; (2) it is doubtful that there is an id, ego, and superego; (3) most dreams may very likely be meaningless; and (4) human motivation, even unconscious motivation, is about a lot more than sex. In the end, because he was most interested in certain kinds of human mental malfunctioning, Freud is probably best thought of as a physician, a proponent and early explorer of human mental health; he was not an experimental cognitive psychologist.

ABSTRACT: Qualia, the subjectively known qualities of conscious experience, are judged by many philosophers and scientists to lie beyond the domain of scientific explanation, thus making the conscious mind partly incomprehensible to the objective physical sciences. Some, like Kripke and Chalmers, employ modal logic to argue that explanations of qualia are impossible in principle. I argue that there already exist perfectly normal scientific explanations of qualia, and rebut the arguments of those who deny this possibility.

The question about the potential for consciousness of artificial systems has often been addressed using thought experiments, which are often problematic in the philosophy of mind. A more promising approach is to use real experiments to gather data about the correlates of consciousness in humans, and develop this data into theories that make predictions about human and artificial consciousness. A key issue with an experimental approach is that consciousness can only be measured using behavior, which places fundamental limits on our (...) ability to identify the correlates of consciousness. This paper formalizes these limits as a distinction between type I and type II potential correlates of consciousness (PCCs). Since it is not possible to decide empirically whether type I PCCs are necessary for consciousness, it is indeterminable whether a machine that lacks neurons or hemoglobin, for example, is potentially conscious. A number of responses have been put forward to this problem, including suspension of judgment, liberal and conservative attribution of the potential for consciousness and a psychometric scale that models our judgment about the relationship between type I PCCs and consciousness.

Even if spectrum inversion of various sorts is possible, spectrum inversion without a difference in representation is not. So spectrum inversion does not pose a challenge for the intentionalist thesis that, necessarily, within a given sense modality, if two experiences are alike with respect to content, they are also alike with respect to their phenomenal character. On the contrary, reflection on variants of standard cases of spectrum inversion provides a strong argument for intentionalism. Depending on one’s views about the possibility (...) of spectrum inversion, the impossibility of spectrum inversion without a difference in representation can also be used as an argument against a variety of reductive theories of mental representation.

The existence of quantum correlates of consciousness (QCC) is doubtful from a scientific perspective. But even if their existence were verified, philosophical problems would remain. On the other hand, there could be more to QCC than meets the sceptic's eye: • QCC might be useful or even necessary for a better understanding of conscious experience or quantum physics or both. The main reasons for this are: the measurement problem (the nature of observation, the mysterious collapse of the wave function, etc.), (...) ostensibly shared features of quantum phenomena and conscious phenomena (e.g., complementarity, nonspatiality, acausality, spontaneity, and holism) and connections (ontology, causation, and knowledge), the qualia problem (subjectivity, explanatory gap etc.). But there are many problems, especially questions regarding realism and the nature and role of conscious observers; • QCC are conceptually challenging, because there are definitory problems and some crucial ontological and epistemological shortcomings. It is instructive to compare them with recent proposals for understanding neural correlates of consciousness (NCC). QCC are not sufficient for a quantum theory of mind, nor might they be necessary except perhaps in a very broad sense; • QCC are also empirically challenging. Nevertheless, QCC could be relevant and important for the mindbody problem: QCC might reveal features that are necessary at least for behavioral manifestations of human consciousness. But QCC are compatible with very different proposals for a solution of the mind-body problem. This seems to be both advantageous and detrimental. QCC restrict accounts of nomological identity. The discovery of QCC cannot establish a naturalistic theory of mind alone. But there are also problems with QCC in the framework of other ontologies. (shrink)

It has been suggested, on the one hand, that quantum states are just states of knowledge; and, on the other, that quantum theory is merely a theory of correlations. These suggestions are confronted with problems about the nature of psycho-physical parallelism and about how we could define probabilities for our individual future observations given our individual present and previous observations. The complexity of the problems is underlined by arguments that unpredictability in ordinary everyday neural functioning, ultimately stemming from small-scale uncertainties (...) in molecular motions, may overwhelm, by many orders of magnitude, many conventionally recognized sources of observed ``quantum'' uncertainty. Some possible ways of avoiding the problems are considered but found wanting. It is proposed that a complete understanding of the relationship between subjective experience and its physical correlates requires the introduction of mathematical definitions and indeed of new physical laws.

Although they may differ on the reason why, many philosophers hold that it is a priori that an object is red if and only if it is such as to look red to normal observers in normal conditions.
