The aim of this paper is to reinforce anti-physicalism by extending the hard problem to a specific kind of intentional states. For reaching this target, I investigate the mental content of the new intentional states of Jackson’s Mary. I proceed in the following way: I start analyzing the knowledge argument, which highlights the hard problem tied to phenomenal consciousness. In a second step, I investigate a powerful physicalist reply to this argument: the phenomenal concept strategy. In a third step, I (...) propose a constitutional account of phenomenal concepts that captures the Mary scenario adequately, but implies anti-physicalist referents. In a last step, I point at the ramifications constitutional phenomenal concepts have on the constitution of Mary’s new intentional states. Therefore, by focusing the attention on phenomenal concepts, the so-called hard problem of consciousness will be carried over to the alleged easy problem of intentional states as well. (shrink)

The central attempt of this paper is to explain the underlying intuitions of Frank Jackson’s “Knowledge Argument” that the epistemic gap between phenomenal knowledge and physical knowledge points towards a corresponding ontological gap. The first step of my analysis is the claim that qualia are epistemically special because the acquisition of the phenomenal concept of a quale x requires the experience of x. Arguing what is so special about phenomenal concepts and pointing at the inherence-relation with the qualia they pick (...) out, I give compelling reasons for the existence of ontologically distinct entities. Finally I conclude that phenomenal knowledge is caused by phenomenal properties and the instantiation of these properties is a specific phenomenal fact, which can not be mediated by any form of descriptive information. So it will be shown that phenomenal knowledge must count as the possession of very special information necessarily couched in subjective, phenomenal conceptions. (shrink)

I argue that an experience’s sensuous elements play an ineliminable role in our being intentionally directed upon an entity through perception. More specifically, I argue that whenever we appreciate a sensuous element in experience, we appreciate an intrinsic and irreducibly phenomenal aspect of experience that I call phenomenal presence – an aspect of experience that I show is central to its presentational character – and that the appreciation of phenomenal presence is necessary for perceptual intentionality. If an experience is to (...) possess intentionality, the experience itself must make an entity available as an object of perceptually-based singular beliefs and the experiencing subject, by virtue of undergoing the experience, must in some sense be able to appreciate that it has done so. Phenomenal presence is necessary for perceptual intentionality because it plays an ineliminable role in making an entity available to its subject in this way. (shrink)

In recent years the 'zombie argument' has come to occupy a central role in the case against physicalist views of consciousness, in large part because of the powerful advocacy it has received from David Chalmers.1 In this paper I seek to neutralize it by showing that a parallel argument can be run for physicalism, an argument turning on the conceivability of what I shall call anti-zombies. I shall argue that the result is a stand-off, and that the zombie argument offers (...) no independent reason to reject physicalism. (shrink)

Howell Pacific Philosophical Quarterly, 89, 348–358 and Mizrahi and Morrow Ratio, 28, 1–13 offer a group of reductio arguments to rebut the CP thesis, i.e., the hypothesis that ideal conceivability entails possibility. Each of them has a conceivability premise: it is ideally conceivable that CP is false. According to the same CP, one can infer that CP’s being false is possible, from which it follows that CP is false. In other words, CP is shown to be self-defeating and therefore false (...) if any of these reductio arguments is proved sound. In this paper, I aim to disprove these arguments. I first show that neither Howell nor Mizrahi & Morrow provide adequate justification for their conceivability premises. I go on to argue that these reductio arguments face a dilemma: either their conceivability premises cannot be adequately justified, or they are redundant. Finally, I argue that, although this dilemma resists the reductio arguments against CP, on the other hand, it also reveals that CP lacks epistemic fruitfulness: it is of no practical use in the realm of apriority as well as necessity.

This paper makes and defends four interrelated claims. First: most conscious experiences are complex in the sense that they have discernible constituent structure with discernible parts that can feature as parts of other experiences, and might occur as standalone experiences. Second: complex experiences have simple constituents that have no further discernible parts. Third: the phenomenal quality of having a complex experience is jointly determined by the phenomenal quality of its simple constituents plus the phenomenal structure simple constituents are organised into. (...) And fourth: physical descriptions can convey all the relevant information about the discernible phenomenal structure of conscious experiences. The combination of these four claims tells us that there is no further explanatory gap related to the phenomenal quality of complex experiences given that one is familiar with the phenomenal qualities of the simple parts constituting the complex experience in question, and that it is possible to acquire knowledge about the phenomenal quality of yet unexperienced complex experiences on the basis of previous acquaintances with constituent parts plus structural information. That is, the paper argues for a ‘summation’ model of phenomenal qualities. (shrink)

The phenomenal character of conscious experience has long been regarded as the major problem for physicalist accounts of consciousness. In recent years, defenders of physicalism have typically been relying on the so-called Phenomenal Concept Strategy to avoid dualism. In this paper, we argue with PCS that cognitive-physicalistic explanations can account for the peculiarities of phenomenal character. However, we think that the conceptual features PCS investigates are not the genuine causes of the special characteristics of phenomenal consciousness but only symptoms, which (...) can themselves be explained in terms of the features of the sensory-perceptual representations underlying conscious experiences, namely that some, but not all, of these states are representationally unstructured. (shrink)

The novel approach presented in this paper accounts for the occurrence of the epistemic gap and defends physicalism against anti-physicalist arguments without relying on so-called phenomenal concepts. Instead of concentrating on conceptual features, the focus is shifted to the special characteristics of experiences themselves. To this extent, the account provided is an alternative to the Phenomenal Concept Strategy. It is argued that certain sensory representations, as accessed by higher cognition, lack constituent structure. Unstructured representations could freely exchange their causal roles (...) within a given system which entails their functional unanalysability. These features together with the encapsulated nature of low level complex processes giving rise to unstructured sensory representations readily explain those peculiarities of phenomenal consciousness which are usually taken to pose a serious problem for contemporary physicalism. I conclude that if those concepts which are related to the phenomenal character of conscious experience are special in any way, their characteristics are derivative of and can be accounted for in terms of the cognitive and representational features introduced in the present paper.

Introspection presents our phenomenal states in a manner otherwise than physical. This observation is often thought to amount to an argument against physicalism: if introspection presents phenomenal states as they essentially are, then phenomenal states cannot be physical states, for we are not introspectively aware of phenomenal states as physical states. In this article, I examine whether this argument threatens a posteriori physicalism. I argue that as along as proponents of a posteriori physicalism maintain that phenomenal concepts present the nature (...) of their referents in a partial and incomplete manner, a posteriori physicalism is safe. (shrink)

I defend the claim that physicalism is not committed to the view that non-phenomenal macrophysical truths are a priori entailed by the conjunction of microphysical truths , basic indexical facts , and a 'that's all' claim . I do so by showing that Chalmers and Jackson's most popular and influential argument in support of the claim that PIT ⊃ M is a priori, where 'M' stands for any ordinary, non-phenomenal, macroscopic truth, falls short of establishing its conclusion. My objection to (...) Chalmers and Jackson's argument takes the form of a nested dilemma. Let 'Conceptual Competence Principle ' stand for the following claim: for any complete microphysical description D of a world w, a subject who is in possession of and competent with a macrophysical concept C is capable of determining a priori the extension of C. Either Jackson and Chalmers accept CCP or not. If the latter, then they cannot demonstrate that the conditional PIT ⊃ M is a priori. If the former, then they have a choice: they can either cite reasons that support the principle or argue that the principle should be taken for granted since it is entailed by the very notion of conceptual competence. But both alternatives are problematic. In regard to the first horn of this latter dilemma, I show not only that there are no good reasons to support the principle, but that there are also reasons to reject it. In regard to the second horn, I show that it cannot be the case that CCP is part of the very notion of conceptual competence. The conceptual capacity expressed by CCP requires that certain bridge principles or conditionals, which link the microphysical level to the macroscopic level, are either implicitly or explicitly given to the subject. But, as I argue, Chalmers and Jackson have no way of accounting for these bridge principles or conditionals in a manner that does not trivialize their position. (shrink)

I respond to Chalmers’ (2006, 2010) objection to the Phenomenal Concept Strategy (PCS) by showing that his objection is faced with a dilemma that ultimately undercuts its force. Chalmers argues that no version of PCS can posit psychological features that are both physically explicable and capable of explaining our epistemic situation. In response, I show that what Chalmers calls ‘our epistemic situation’ admits either of a phenomenal or of a topic-neutral characterization, neither of which supports Chalmers’ objection. On the one (...) hand, if our epistemic situation is characterized phenomenally, then Chalmers’ demand that PCS should explain our epistemic situation is misplaced. PCS can explain our epistemic situation only if there is a reductive explanation of consciousness. But according to PCS, no reductive explanation of consciousness can be given. On the other hand, if our epistemic situation is characterized topic-neutrally, then PCS is not only physically explicable, but it also explains our epistemic situation. Either way, PCS is safe.

A celebrated problem for representationalist theories of phenomenal character is that, given externalism about content, these theories lead to externalism about phenomenal character. While externalism about content is widely accepted, externalism about phenomenal character strikes many philosophers as wildly implausible. Even if internally identical individuals could have different thoughts, it is said, if one of them has a headache, or a tingly sensation, so must the other. In this paper, I argue that recent work on phenomenal concepts reveals that, contrary (...) to appearances, this standard conjunction of externalism about content and internalism about phenomenal character is ultimately untenable on other models of phenomenal character as well, including even “qualia realism.” This would be significant for a number of reasons. The first is patent: it would undermine a primary objection to representationalism. The fact that representationalism is incompatible with the conjunction would be no serious problem for representationalism if no other plausible model of phenomenal character is compatible with it. The second is that the many philosophers who embrace the conjunction would be forced to abandon one of the two views; externalism would be true either of both content and phenomenal character, or of neither. Likewise, those philosophers who have taken a stance on only one of the two internalism/externalism debates would have to be seen as thereby committed to a particular stance on the other. The third reason stems from the fact that qualia realism typically goes hand in hand with internalism about phenomenal character. To the extent that it does, my argument would reveal that qualia realism is itself in tension with externalism about content. This would perhaps be the most surprising result of all. (shrink)

The Phenomenal Concept Strategy offers the physicalist perhaps the most promising means of explaining why the connection between mental facts and physical facts appears to be contingent even though it is not. In this article, we show that the large body of evidence suggesting that our concepts are often embodied and grounded in sensorimotor systems speaks against standard forms of the PCS. We argue, nevertheless, that it is possible to formulate a novel version of the PCS that is thoroughly in (...) keeping with embodied cognition, focuses on features of physical concepts, and succeeds in explaining the appearance of contingency.

One of the main strategies against conceivability arguments is the so-called phenomenal concept strategy, which aims to explain the epistemic gap between physical and phenomenal truths in terms of the special features of phenomenal concepts. Daniel Stoljar has recently argued that the phenomenal concept strategy has failed to provide a successful explanation of this epistemic gap. In this paper my aim is to defend the phenomenal concept strategy from his criticisms. I argue that Stoljar has misrepresented the resources of the (...) strategy, which can indeed accomplish the required explanatory task, once it is properly understood. (shrink)

What is the mind? Is consciousness a process in the brain? How do our minds represent the world? Philosophy of Mind: Classical and Contemporary Readings is a grand tour of writings on these and other perplexing questions about the nature of the mind. The most comprehensive collection of its kind, the book includes sixty-three selections that range from the classical contributions of Descartes to the leading edge of contemporary debates. Extensive sections cover foundational issues, the nature of consciousness, and the (...) nature of mental content. Three of the selections are published here for the first time, while many other articles have been revised especially for this volume. Each section opens with an introduction by the editor. Philosophy of Mind is suitable for students at all levels and also for general readers. (shrink)

Two-dimensional (2D) semantics is a formal framework that is used to characterize the meaning of certain linguistic expressions and the entailment relations among sentences containing them. 2D semantics has also been applied to thought contents. In contrast with standard possible worlds semantics, 2D semantics assigns extensions and truth-values to expressions relative to two possible world parameters, rather than just one. So a 2D semantic framework provides finer-grained semantic values than those available within standard possible world semantics, while using the same (...) basic model-theoretic resources. The 2D framework itself is just a formal tool. To develop a semantic theory for someone’s language, a proponent of 2D semantics must do three things: (i) explain what exactly the two possible world parameters represent, (ii) explain the rules for assigning 2D semantic values to a person’s words and sentences, and (iii) explain how 2D semantic values help in understanding the meanings of the person’s words and sentences.

One of the leading concerns animating current philosophy of mind is that, no matter how good a scientific account is, it will leave out what its like to be conscious. The challenge has thus been to study or at least explain away that qualitative dimension. Pursuant with that aim, I investigate how philosophy of signs in the Peircean tradition can positively reshape ongoing debates. Specifically, I think the account of iconic or similarity-based reference we find in semiotic theory offers a (...) more promising variant of the phenomenal concept strategy. Philosophers who endorse this strategy think that the difficulties we have fitting conscious qualia into a scientific picture may owe to the peculiar nature of indexical concepts. They point to the fact that, when we try to convey the feel of our experiences, we employ context-dependent gestures and/or utterances that are indexed to perspectives unique to each person. However, according to the theory I defend, there are three ways signs can refer, namely by convention, causal contact, and similarity. Since similarity is not reducible to proximity, I argue that a theory of reference that turns on shared quality can bypass some of the implausible consequences that plague indexical accounts. In the first chapter, I describe the apparatus needed to make sense of this claim. In the second chapter, I present my account of iconic reference. In the third chapter, I justify my reliance on a distinction that is less than real yet more than nominal. In the fourth chapter, I sketch a trinitarian metaphysics well-suited to house the foregoing account of qualia. (shrink)

This paper is a new defense of type-B materialism against Jackson’s knowledge argument (1982) inspired by the Kantian main opposition between concepts and sensible intuitions. Like all materialists of type B, I argue that on her release from her black-and-white room, Mary makes cognitive progress. However, contrary to the so-called phenomenal concept strategy (henceforth PCS), I do not think that such progress can be accounted for in terms of the acquisition of new concepts. I also reject Tye’s recent account of (...) Mary’s cognitive progress as the acquisition of a “thing-knowledge.” What is crucial is not the Russellian opposition between knowing things and knowing truths but rather the Kantian opposition between conceptual and nonconceptual representations of the same thing (property). Mary’s phenomenal knowledge is here accounted for as the result of the cooperation of her newly acquired nonconceptual representation of the same phenomenal redness (the same thing) she had a conceptual representation before. As that new nonconceptual representation carries information about the same physical property she already represented but is now coded in analog rather than in digital form (Dretske, 1981), that nonconceptual representation can be accounted for in physical terms as Chalmers’s Master argument requires. Nevertheless, that representation can account for Mary’s cognitive progress since it carries information coded in analog form, something that the imprisoned she could never possess. (shrink)

This paper is both systematic and historical in nature. From a historical viewpoint, I aim to show that to establish Wittgenstein’s claim that “an ‘inner process’ stands in need of outward criteria” (PI §580) there is an enthymeme in Wittgenstein’s private language argument (henceforth PLA) overlooked in the literature, namely Wittgenstein’s suggestion that both perceptual and bodily experiences are transparent in the relevant sense that one cannot point to a mental state and wonder “What is that?” From a systematic viewpoint, (...) I aim to show that Wittgenstein’s PLA teaches us that the prevailing picture of the nature of phenomenal concepts (henceforth PCs) is upside down: we can only introspectively know what is going on inside our heads after we learn of what is going on outside (PI §580). In this regard, I aim to defend two associate claims against the prevailing view of PCs on the basis of PLA. First, by means of transparency, I aim to show that there is no de re awareness of our private sensation that could determine the meaning of sensation words; for example, I am never aware of the phenomenal blueness of my experience of something blue. The second associated claim is that introspective self-knowledge of our private sensations is always de dicto. We can only know introspectively that phenomenal blueness is the phenomenal character of the experience we are undergoing after we have learned that (de dicto knowledge) blue is the color that usually causes us that kind of experience. Likewise, we can only introspectively know that pain is the phenomenal character of the experience we are undergoing after we have learned that pain is what usually causes some typical pain behavior.

How does one know the phenomenal character of one’s own experience? I aim to present and defend a new view of the epistemology of qualia that addresses this issue. My view results from a reworking of Dretske’s displaced perception model. The guiding line is the key Wittgensteinian insight of his Private Language Argument, namely the claim that no inner perception of qualia can justify our corresponding qualia beliefs. My reworking of the original model starts with the rejection of Dretske’s representationalism, (...) as well as any other metaphysical views about the ultimate nature of qualia. The reworking of the displaced perception model I am proposing is supposed to be compatible with any available metaphysical view on qualia. The second step consists of rejecting the epistemological misgivings of the original model, namely the view that knowing qualia requires “connecting beliefs” along with “meta-representations.” Yet, Dretske’s crucial mistake has been to force knowledge of qualia into the “belief-box.” As a matter of fact, there is only one belief involved in introspecting qualia, namely the qualia-belief itself. The third final step is this. Assuming the key Wittgensteinian insight, I argue that introspection of qualia is a process that is both epis- temically reliable and automatic. It is reliable because it dispenses with justification of any beliefs whatsoever. Moreover, it is automatic because it also dispenses with reflexive connecting beliefs. For example, it takes nonconceptual awareness of the color blue as an input and automatically yields the belief that phenomenal blue is the conscious character of my experience of the sky as an output just by employing the concept BLUE.

This thesis explores attempts to characterise the structure of reality. Three notions stand out: Lewisian naturalness, Sider’s ‘structure’, and grounding, where the latter has become the most popular way to characterise the structure of reality in the contemporary literature. I argue that none of these notions, as they are currently understood, are suited for limning the metaphysical structure of reality. In the first part of the thesis I argue that, by the lights of the relevant theories, both naturalness and structure (...) fall short of the theoretical role carved out for those posits. In the second part of the thesis I present two challenges to the ‘orthodox’ conception of grounding. The first contests the standard assumption that grounding is asymmetric, both by citing what I take to be best described as symmetric instances of grounding, and by developing and arguing for a new theory of metaphysical structure – ‘metaphysical interdependence’ – which takes grounding to be nonsymmetric. The second challenge concerns the relationship between grounding and explanation, and leads to a dilemma for the grounding theorist. My proposed resolution to the dilemma is to adopt an antirealist approach to grounding, which I further motivate and develop in the final chapter. (shrink)

If I am aware that p, say, that it is raining, is it the case that I must be aware that I am aware that p? Does introspective or object-awareness entail the apprehension of mental states as being of some kind or another: self-monitoring or intentional? That is, are cognitive events implicitly self-aware or is “self-awareness” just another term for metacognition? Not surprisingly, intuitions on the matter vary widely. This paper proposes a novel solution to this classical debate by reframing (...) the problem of self-knowledge in terms of the relation between phenomenal concepts and phenomenal knowledge. Concepts of consciousness such as “introspective awareness” and “reflexive self-awareness” are grounded in phenomenal experiences rather than physical events and processes. As such they yield a different kind of self-knowledge than what can be gained by applying externalist conceptual schemas to understanding the mind. I argue that Dharmakīrti’s theory of content can be seen as endorsing the efficacy of phenomenal experience as a vehicle for self-knowledge. (shrink)

Williamson’s anti-luminosity argument has been thought to be in tension with the doctrine that we enjoy privileged epistemic access to our own mental states. In this paper, I will argue that the tension is only apparent. Friends of privileged access who accept the conclusion of the argument need not give up the claim that our beliefs about our own mental states are mostly or invariably right, nor the view that mental states are epistemically available to us in a way that (...) renders everything within our mind ‘open to view’ – arguably, two main pillars of their doctrine. What they need to reject is the idea that the mental is a realm whose ’determinacy’ or ’fineness of grain’ never escapes our appreciation. This idea – I will suggest – is not essential to privileged access and defenders of the doctrine should not be afraid to give it up. (shrink)

In this paper, I examine the relationship between physicalism and property dualism in the light of the dialectic between anti-physicalist arguments and physicalist responses. Upon rehearsing the moves of each side, it is hard not to notice that there is a puzzling symmetry between dualist attacks on physicalism and physicalist replies. Each position can be developed in a way to defend itself from attacks from the other position, and it seems that there are neither a priori nor a posteriori grounds (...) to choose between the two. I suggest that the reason for the intractability of the disagreement, perhaps surprisingly, is they are both true: physicalism and dualism are formulated in terms of different conceptual schemes, each involving basic metaphysical concepts such as possibility, necessity, law and property. My proposal is that this means that there is no real disagreement in fact; both schemes get at the same reality, in different ways. -/- . (shrink)

To make progress on the problem of consciousness, we have to confront it directly. In this paper, I first isolate the truly hard part of the problem, separating it from more tractable parts and giving an account of why it is so difficult to explain. I critique some recent work that uses reductive methods to address consciousness, and argue that such methods inevitably fail to come to grips with the hardest part of the problem. Once this failure is recognized, the (...) door to further progress is opened. In the second half of the paper, I argue that if we move to a new kind of nonreductive explanation, a naturalistic account of consciousness can be given. I put forward my own candidate for such an account: a nonreductive theory based on principles of structural coherence and organizational invariance, and a double-aspect theory of information.

Abstract. The dissertation defends the thesis that the mind-body problem arises against the background of the elimination of the manifest physical world, and that the only satisfactory response to it is to take back that elimination and thus to dissolve the problem. Various materialist and dualist responses are shown to be inadequate. They are only different forms of ontological fundamentalism – physics fundamentalism and consciousness fundamentalism – that lead to ultimately meaningless metaphysical constructions. By contrast, on the ontologically pluralist view (...) outlined here, the fact that the entire spatiotemporal world has a physical microstructure is compatible with a naive realism with regard to both the manifest physical world and to consciousness. We only need to ascribe physical microstructures to both while identifying neither with these structures. After an introduction that identifies the elimination of the manifest physical world in modernity as the metaphysical background of the mind-body problem and describes the dilemmatic situation created by the typical reactions to it, the first chapter attempts to clarify what consciousness is. The second chapter then discusses some of the standard formulations of the so-called “puzzle” or “mystery” of consciousness. It is shown that these cannot be transformed into a genuine, answerable question. The notion that other macrophenomena can be explained much better than consciousness, perhaps even in a completely transparent way, is revealed to be an illusion, an artefact of the tacit elimination of the manifest physical world. In the third chapter, the thesis that consciousness has spatial properties is defended against various forms of skepticism. The fourth chapter begins the debate with the mind-body identity theory by discussing various positions on identity statements in the philosophy of language. This discussion leads to the conclusion that the idea of informative identity statements is meaningless. On this basis, the notion of an empirically contentful so-called “scientific identification” of consciousness phenomena with their neuronal correlates is criticized in the fifth chapter. The sixth chapter argues that it is possible to dissolve the problem of mental causation if a physiological and ultimately also a microphysical structure is ascribed to consciousness. In a concluding reflection it is explained what it means that the present suggestion amounts to a dissolution rather than a solution of the traditional mind-body problem. Zusammenfassung. In dieser Arbeit wird die These vertreten, dass das Leib-Seele- Problem vor dem Hintergrund der Elimination der manifesten physischen Welt entsteht und die einzig befriedigende Reaktion darauf nur sein kann, diese Elimination wieder rückgängig zu machen und das Problem damit aufzulösen. Materialistische und dualistische Reaktionen werden als unzulänglich erwiesen. Sie sind nur verschiedene Formen eines ontologischen Fundamentalismus – Physikfundamentalismus und Bewusstseinsfundamentalismus – der zu letztlich sinnlosen metaphysischen Konstruktionen führt. Dagegen ist nach dem hier vertretenen ontologischen Pluralismus die Tatsache, dass die gesamte raumzeitliche Welt eine physikalische Mikrostruktur hat, mit einem naiven Realismus sowohl in Bezug auf die manifeste physische Welt als auch in Bezug auf das Bewusstsein vereinbar. Wir müssen nur beiden eine physikalische Mikrostruktur zuschreiben ohne sie mit dieser zu idenfizieren. Nachdem in der Einleitung die Elimination der manifesten physischen Welt in der Neuzeit als der metaphysische Hintergrund des Leib-Seele-Problems identifiziert und die durch die typischen Reaktionen darauf entstehende dilemmatische Aus- gangssituation beschrieben worden ist, klärt das erste Kapitel, was Bewusstsein ist. Im zweiten Kapitel werden dann einige gängige Formulierungen des so genannten „Bewusstseinsrätsels“ vorgestellt. Es wird gezeigt, dass diese sich nicht in eine wirklich beantwortbare Frage transformieren lassen. Die Vorstellung, dass sich andere Makrophänomene wesentlich besser erklären lassen als das Bewusstsein, oder gar in vollständig transparenter Weise, wird als Illusion, als Artefakt der stillschweigenden Elimination der manifesten Welt erwiesen. Im dritten Kapitel wird die These, dass das Bewusstsein räumliche Eigenschaften hat, gegen verschiedene Formen der Skepsis verteidigt. Im vierten Kapitel beginnt die Auseinandersetzung mit der Identitätstheorie mit einer Diskussion sprachphilosophischer Positionen zu Identitätsaussagen, die die These begründet, dass die Vorstellung informativer Identitätsaussagen sinnlos ist. Auf dieser Grundlage wird im fünften Kapitel die Vorstellung einer empirisch gehaltvollen so genannten „wissenschaftlichen Identifikation“ von Bewusstseinsphänomenen mit ihren neuronalen Korrelaten kritisiert. Im sechsten Kapitel wird gezeigt, dass sich das Problem mentaler Verursachung auflösen lässt, wenn man Bewusstseinsphänomenen eine physiologische und letztlich auch physikalische Mikrostruktur zuschreibt. In einer Schlussbetrachtung wird erläutert, warum der Vorschlag in dieser Arbeit eine Auflösung statt einer Lösung des Leib-Seele-Problems darstellt. (shrink)

In contemporary philosophy of mind, the conceivability argument against physicalism is often used to support a form of dualism, which takes consciousness to be ontologically fundamental and distinct from physical matter. Recently, some proponents of the conceivability argument have also shown interest in panpsychism, which is the view that mentality is ubiquitous in the natural world. This paper examines the extent to which panpsychism can be sustained if the conceivability argument is taken seriously. I argue that panpsychism’s ubiquity claim permits (...) a strong reading or a weak reading. This presents a dilemma. On the one hand, the strong reading, which is typically characterised as a form of monism, is undermined by the conceivability argument. On the other hand, the weak reading, while compatible with the conceivability argument, turns out just to be a special case of dualism. I also show that the related position of panprotopsychism cannot provide a tenable monist position because it too cannot withstand the challenge of the conceivability argument. Therefore, if the conceivability argument is taken seriously, then we are committed to a dualist metaphysics, regardless of whether or not we accept the ubiquity claim. (shrink)

I elaborate and defend a set of metaphysical and epistemic claims that comprise what I call the acquaintance approach to introspective knowledge of the phenomenal qualities of experience. The hallmark of this approach is the thesis that, in some introspective judgments about experience, (phenomenal) reality intersects with the epistemic, that is, with the subject’s grasp of that reality. In Section 1 of the paper I outline the acquaintance approach by drawing on its Russellian lineage. A more detailed picture of the (...) approach emerges in succeeding sections, which respond to a range of objections. Some critics charge that approaches of this sort are overly idealized, in that they ignore the cognitive flaws and limitations of actual human beings. I begin to address these worries in Section 2, by arguing that the epistemic commitments of the acquaintance approach are in fact relatively modest. In Section 3, I sketch a picture of introspective reference that explains how phenomenal reality can intersect with the epistemic in a phenomenal judgment, as the acquaintance approach requires. Drawing on this picture of introspective reference, Section 4 sets out a practical strategy for achieving knowledge by acquaintance. Some contemporary acquaintance theorists (BonJour 2003, Fumerton 1996) employ demanding epistemic standards for knowledge by acquaintance, standards beyond those mandated by the acquaintance approach. In Section 5 I show that instances of introspective knowledge that meet less demanding standards can satisfy the acquaintance approach’s epistemic commitments. The final sections concern the most direct challenges to the acquaintance approach, which target the claim that phenomenal reality intersects with the epistemic. According to one such challenge, this claim is belied by the fact that possessing a phenomenal concept is a matter of having certain dispositions. Section 6 draws on a discussion by Sosa (2003) to articulate this challenge, and responds to it on behalf of the acquaintance approach. Section 7 addresses Stalnaker’s (2008) worry that, if phenomenal reality intersected with the epistemic, phenomenal information would be incommunicable. (shrink)

The idea of representation has been central in discussions of intentionality for many years. But only more recently has it begun playing a wider role in the philosophy of mind, particularly in theories of consciousness. Indeed, there are now multiple representational theories of consciousness, corresponding to different uses of the term "conscious," each attempting to explain the corresponding phenomenon in terms of representation. More cautiously, each theory attempts to explain its target phenomenon in terms of _intentionality_, and assumes that intentionality (...) is representation. (shrink)

Frank Jackson’s famous Knowledge Argument moves from the premise that complete physical knowledge about experiences is not complete knowledge about experiences to the falsity of physicalism. Some physicalists (e.g., John Perry) have countered by arguing that what Jackson’s Mary, the perfect scientist who acquires all physical knowledge about experiencing red while being locked in a monochromatic room, lacks before experiencing red is merely a piece of recognitional knowledge of an identity, and that since lacking a piece of recognitional knowledge of (...) an identity does not entail lacking any pieces of knowledge of worldly facts, physicalism is safe. I will argue that what Mary lacks in her room is not merely a piece of recognitional knowledge of an identity and that some physicalists have failed to see this because of a failure to appreciate that Mary’s epistemic progress when she first experiences red has two different stages. While the second epistemic stage can perhaps be plausibly considered as acquiring merely a piece of recognitional knowledge of an identity, there is good reason to think that the first epistemic stage cannot be thus considered.

This compilation of references includes all references for the knowledge-how chapters included in Bengson & Moffett's edited volume. The volume and the compilation of references may serve as a good starting point for people who are unfamiliar with the philosophical literature on knowledge-how.

Feelings and experiences vary widely. For example, I run my fingers over sandpaper, smell a skunk, feel a sharp pain in my finger, seem to see bright purple, become extremely angry. In each of these cases, I am the subject of a mental state with a very distinctive subjective character. There is something it is like for me to undergo each state, some phenomenology that it has. Philosophers often use the term ‘qualia’ (singular ‘quale’) to refer to the introspectively accessible, (...) phenomenal aspects of our mental lives. In this standard, broad sense of the term, it is difficult to deny that there are qualia. Disagreement typically centers on which mental states have qualia, whether qualia are intrinsic qualities of their bearers, and how qualia relate to the physical world both inside and outside the head. The status of qualia is hotly debated in philosophy largely because it is central to a proper understanding of the nature of consciousness. Qualia are at the very heart of the mindbody problem.

1 Non-reductive physicalists deny that there is any explanation of mentality in purely physical terms, but do not deny that the mental is entirely determined by and constituted out of underlying physical structures. There are important issues about the stability of such a view which teeters on the edge of explanatory reductionism on the one side and dualism on the other (see Kim 1998). 2 Save perhaps for eliminative materialism (see Churchland 1981 for a classic exposition). In fact, however, while.

The notion of a "mental representation" is, arguably, in the first instance a theoretical construct of cognitive science. As such, it is a basic concept of the Computational Theory of Mind, according to which cognitive states and processes are constituted by the occurrence, transformation and storage (in the mind/brain) of information-bearing structures (representations) of one kind or another.

Functionalism in the philosophy of mind is the doctrine that what makes something a mental state of a particular type does not depend on its internal constitution, but rather on the way it functions, or the role it plays, in the system of which it is a part. This doctrine is rooted in Aristotle's conception of the soul, and has antecedents in Hobbes's conception of the mind as a “calculating machine”, but it has become fully articulated (and popularly endorsed) only (...) in the last third of the 20th century. Though the term ‘functionalism’ is used to designate a variety of positions in a variety of other disciplines, including psychology, sociology, economics, and architecture, this entry focuses exclusively on functionalism as a philosophical thesis about the nature of mental states.

Qualia inversion thought experiments are ubiquitous in contemporary philosophy of mind. The most popular kind is one or another variant of Locke's hypothetical case of.

Frankish positions his view, illusionism about qualia (a.k.a. eliminativist physicalism), in opposition to what he calls radical realism (dualism and neutral monism) and conservative realism (a.k.a. non-eliminativist physicalism). Against radical realism, he upholds physicalism. But he goes along with key premises of the Gap Arguments for radical realism, namely, 1) that epistemic/explanatory gaps exist between the physical and the phenomenal, and 2) that every truth should be perspicuously explicable from the fundamental truth about the world; and he concludes that because (...) physicalism is true, there could be no phenomenal truths, and no qualia. I think he is wrong to accept 2); and even if he was right to accept it, the more plausible response would be not to deny the existence of qualia but to deny physicalism. In either case, denying the existence of qualia is the wrong answer. I present a physicalist realist alterative that refutes premise 2 of the Gap Argument; I also make a general case against the scientism that accompanies Frankish’s metaphysics. (shrink)

This article is about the special, subjective concepts we apply to experience, called “phenomenal concepts”. They are of special interest in a number of ways. First, they refer to phenomenal experiences, and the qualitative character of those experiences whose metaphysical status is hotly debated. Conscious experience strike many philosophers as philosophically problematic and difficult to accommodate within a physicalistic metaphysics. Second, PCs are widely thought to be special and unique among concepts. The sense that there is something special about PCs (...) is very closely tied up with features of the epistemic access they afford to qualia. When we deploy phenomenal concepts introspectively to some phenomenally conscious experience as it occurs, we are said to be acquainted with our own conscious experiences. Accounts of PCs either have to explain the acquaintance relation, or acquaintance with our phenomenal experiences has to be denied. PCs have received much attention in recent philosophy of mind mainly because they figure in arguments for dualism and in physicalist responses to these arguments. The main topic of this article is to explore different accounts of phenomenal concepts and their role in recent debates over the metaphysical status of phenomenal consciousness. (shrink)

In this paper I begin to develop an account of the acquaintance that each of us has with our own conscious states and processes. The account is a speculative proposal about human mental architecture and specifically about the nature of the concepts via which we think in first personish ways about our qualia. In a certain sense my account is neutral between physicalist and dualist accounts of consciousness. As will be clear, a dualist could adopt the account I will offer (...) while maintaining that qualia themselves are non-physical properties. In this case the non-physical nature of qualia may play no role in accounting for the features of acquaintance. But although the account could be used by a dualist, its existence provides support for physicalism. (shrink)

This chapter defends Terence Horgan's claim that any genuinely physicalist position must distinguish itself from (what has been traditionally known as) emergentism. It argues that physicalism is necessarily reductive in character — it must either give a reductive account of apparently non‐physical entities, or a reductive explanation of why there are non‐physical entities. It contends that many recent ‘non‐reductive’ physicalists do not do this, and that because of this they cannot adequately distinguish their view from emergentism. The conclusion is that (...) this is the real challenge posed by Joseph Levine's ‘explanatory gap’ argument: if physicalists cannot close the explanatory gap in Levine's preferred way, they must find some other way to do it. Otherwise their view is indistinguishable from emergentism. (shrink)

Tim Crane's ‘Cosmic Hermeneutics vs. Emergence: The Challenge of the Explanatory Gap’ claims that non‐reductive physicalism must either close the explanatory gap, addressing the challenge famously posed by Levine's argument, or become identical to emergentism. Since no way to close the gap is available, the result is that there can be no interesting philosophical position intermediate between physicalism and emergentism. This chapter argues that if we look at the relation between physicalism and emergentism from the vantage point of reduction, Crane's (...) analysis is rather persuasive. However, if we switch from reduction to causality, its conclusions appear more disputable. In particular, if we shift from ‘novelty and explanation’ to ‘novelty and causality’ as key features of emergent properties, we may introduce a distinction between two kinds of emergentism (moderate and radical) based on their attitude towards the causal inheritance principle. If the causal inheritance principle is accepted (some versions of) moderate emergentism may be considered as non‐trivial forms of non‐reductive physicalism. (shrink)

A central problem in the mind-body debate is the generation problem: how consciousness occurs in a universe understood as primarily non-conscious. This problem is particularly bothersome for physicalists. I argue that the generation problem stems from a non-critical presupposition about the nature of reality, namely, that the mental is an exception in the universe, a non-fundamental property. I call this presupposition mental specialism. Despite the fact that mental specialism dogmatically ingrained in the debate, there has been little reason offered either (...) to accept or reject it. And doing so would dissolve the generation problem. But rejecting mental specialism, though it would dissolve the generation problem, would mean accepting another anathema presupposition: panpsychism. The resistance to panpsychism stems from the perception that panpsychism runs counter to science, that it is based on dogmatic metaphysical (even transcendental) arguments, and that it entails doctrines that cannot be accepted by science, such as mysteriousness. This perception is misguided and here I argue that a naturalized panpsychism, one that does not run contrary to science in these ways, can be developed and defended. I argue that consciousness emerges from proto-consciousness, the fundamental property that is disposed to give rise to consciousness. Proto-consciousness is not an arbitrarily posited property; following an important contemporary approach in neuroscience (the integrated information account), I understand proto-consciousness as information. The thesis that consciousness emerges from proto-consciousness elicits a fatal problem with panpsychic theories, the combination problem. This problem is how to account for higher-order conscious properties emerging from proto-conscious properties. I solve the combination problem that by adopting Giuolio Tononi’s Integrated Information Theory of Consciousness and demonstrating emerging higher-order conscious properties just is a system integrating information. Thus information is the fundamental property that, when integrated in a system such as a human being, is consciousness. Proto-consciousness is thus a natural property and the formulated panpsychic theory based upon information is a naturalized panpsychism. (shrink)

Phenomenal Concepts and Phenomenal Knowledge is an edited volume of new essays relating to the debates around phenomenal experience in philosophy of mind. Alter and Walter provide an excellent introduction to the volume, producing a well edited collection of papers that represent some of the most interesting and cutting edge work in the field, and together provide a subtle and complex overview of the contemporary theoretical landscape. In addition, as many of the papers refer to others within the volume, they (...) provide an excellent opportunity for in depth and complex debate between some of the leading theorists at work today. This review concentrates on ways in which papers in the volume further debates around the construal of phenomenal consciousness as physical or non-physical, and also on new responses to the infamous knowledge argument.
