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)

Let's be externalists about perceptual consciousness and think the form of veridical perceptual consciousness includes /seeing this or that mind-independent particular and its colors/. Let's also take internalism seriously, granting that spectral inversion and hallucination can be "phenomenally" the same as normal seeing. Then perceptual consciousness and phenomenality are different, and so we need to say how they are related. It's complicated!<br><br>Phenomenal sameness is (against all odds) /reflective indiscriminability/. I build a "displaced perception" account of reflection on which indiscriminability stems (...) from shared "qualia". Qualia are compatible with direct realism: while they generate an explanatory gap (and colors do not), so does /seeing/; qualia are excluded from perceptual consciousness by its "transparency"; instead, qualia are aspects of thought about the perceived environment. <br><br>The asymmetry between my treatments of color and seeing is grounded in the asymmetry between ignorance and error: while inversion shows that normal subjects are ignorant of the natures of the colors, hallucination shows not that perceivers are ignorant of the nature of seeing but that hallucinators are prone to error about their condition. Past literature has treated inversion and hallucination as on a par: externalists see error in both cases, while internalists see mutual ignorance. My account is so complicated because plausible results require mixing it up. (shrink)

Grounding-theoretic reformulation of Fodor's theory of content that addresses recalcitrant Quinean concerns.

Projectivism is the thesis that we project at least some subjective aspects of perception into what we experience as the world outside ourselves. It is familiar from various phantom pains, afterimages, and hallucinations. Strong Projectivism asserts that all perceptual experiences involve and only involve direct awareness of projected elements. Strong Projectivism is an unpopular and I argue underappreciated variety of intentionalism (or representationalism). It straightforwardly explains the transparency of experience (section 2) and phenomena qualia theorists offer to avoid intentionalism such (...) as blurry vision and spectrum inversion (section 3). Finally, projectivism illuminates residual qualia-friendly cases involving imagination and emotion (section 4). Ultimately, instances of non-projected, non-intentional aspects of experience are hard to identify. Thus, the notion of phenomenal presence drawn from projectivism does justice to a great many of the forces at play in debates surrounding qualia and intentionalism. We should bound toward Strong Projectivism. (shrink)

Saying that psychological states are functional states, the functionalist claims more than that psychological states have functions. Rather, functionalism is the theory that psychological states are defined and constituted by their functions. On this view, what it is to be a psychological state of a certain sort just is and consists entirely of having a certain function. Anything that has that function in a suitable system would therefore be that psychological state. If storing information for later use is the essential (...) function of memory, then anything that has that function counts as a memory. Similarly, one might say that anything that traps or kills mice counts as a mouse trap. (shrink)

Bissell offers a new interpretation and clarification of Rand's definition of art, maintaining that an artwork, like language, functions as a "tool of cognition," and that it does so more specifically as a special kind of microcosm which presents an imaginary world. In particular, he argues that architecture and music are aesthetic microcosms and tools of cognition that re-create reality and embody fundamental abstractions and, thus, contrary to assertions by certain Objectivist writers, are forms of art consistent with Rand's definition (...) and concept.

In this article, I defend the view that we can acquire factual knowledge – that is, contingent propositional knowledge about certain (perceivable) aspects of reality – on the basis of imaginative experience. More specifically, I argue that, under suitable circumstances, imaginative experiences can rationally determine the propositional content of knowledge-constituting beliefs – though not their attitude of belief – in roughly the same way as perceptual experiences do in the case of perceptual knowledge. I also highlight some philosophical consequences of (...) this conclusion, especially for the issue of whether imagination can help us to learn something from fictions. (shrink)

Much of computational cognitive science construes human cognitive capacities as representational capacities, or as involving representation in some way. Computational theories of vision, for example, typically posit structures that represent edges in the distal scene. Neurons are often said to represent elements of their receptive fields. Despite the ubiquity of representational talk in computational theorizing there is surprisingly little consensus about how such claims are to be understood. The point of this chapter is to sketch an account of the nature (...) and function of representation in computational cognitive models. (shrink)

For patients under anesthesia, it is extremely important to be able to ascertain from a scientific, third person point of view to what extent consciousness is correlated with specific areas of brain activity. Errors in accurately determining when a patient is having conscious states, such as conscious perceptions or pains, can have catastrophic results. Here, I argue that the effects of (at least some kinds of) anesthesia lend support to the notion that neither basic sensory areas nor the prefrontal cortex (...) (PFC) is sufficient to produce conscious states. I also argue that it this is consistent with and supportive of the higher-order thought (HOT) theory of consciousness. I therefore disagree in some ways with Mehta and Mashour (2013), who argue that evidence from anesthesia mainly favors a first-order representational (FOR) theory, as opposed to HOT theory (and many other theories, for that matter).

The Problem of Perception is a pervasive and traditional problem about our ordinary conception of perceptual experience. The problem is created by the phenomena of perceptual illusion and hallucination: if these kinds of error are possible, how can perceptual experience be what we ordinarily understand it to be: something that enables direct perception of the world? These possibilities of error challenge the intelligibility of our ordinary conception of perceptual experience; the major theories of experience are responses to this challenge.

Suppose that consciousness is a natural feature of biological organisms, and that it is a capacity or property or process that resides in a single organ. In that case there is a straightforward question about the consciousness organ, namely: How did the consciousness organ come to be formed and why is its presence maintained in those organisms that have it? Of course answering this question might be rather difficult, particularly if the consciousness organ is made of soft tissue that leaves (...) at best indirect fossil records, or if it has been fixed in the populations for such a long time that there are few available examples of organisms that lack the consciousness organ on which to conduct comparative experiments. No doubt there are other confounding practical obstacles as well. But these are just the complications that face biologists and natural historians on a regular basis, and they do not reflect any special problems about the study of consciousness. This is just to say that if consciousness is a natural feature of biological organisms then its origins and history can be studied in the same manner as other features of the biological world. It’s a hard business, but biologists are pretty good at it. (shrink)

This is the Stanford Encyclopedia of Philosophy entry on the contents of perception.

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.

Pain is the most prominent member of a class of sensations known as bodily sensations, which includes itches, tickles, tingles, orgasms, and so on. Bodily sensations are typically attributed to bodily locations and appear to have features such as volume, intensity, duration, and so on, that are ordinarily attributed to physical objects or quantities. Yet these sensations are often thought to be logically private, subjective, self-intimating, and the source of incorrigible knowledge for those who have them. Hence there appear to (...) be reasons both for thinking that pains (along with other similar bodily sensations) are physical objects or conditions that we perceive in body parts, and for thinking that they are not. This apparent paradox is one of the main reasons why philosophers are especially interested in pain. One increasingly popular but still controversial way to deal with this apparent paradox is to defend a perceptual or representational view of pain, according to which feeling pain is in principle no different from undergoing other standard perceptual processes like seeing, hearing, touching, etc. But there are many who think that pains are not amenable to such a treatment. Although it was the treatment of pain as a sensory-discriminative experience that had dominated the philosophical discussions throughout most of the twentieth century, attention to pains’ affective-motivational dimension has gained prominence in recent years.

Doxasticism about our awareness of normative (i.e. justifying) reasons – the view that we can recognise reasons for forming attitudes or performing actions only by means of normative judgements or beliefs – is incompatible with the following triad of claims: -/- (1) Being motivated (i.e. forming attitudes or performing actions for a motive) requires responding to and, hence, recognising a relevant reason. -/- (2) Infants are capable of being motivated. -/- (3) Infants are incapable of normative judgement or belief. -/- (...) It should be clear that (3) is true, given that infants lack the required reflective and conceptual capacities. So doxasticists have to reject either (1) or (2) (or both). But this forced choice may be understood as a dilemma for doxasticism. On the hand, doxasticists may adopt a Kantian approach and reject (2), precisely because they think that motivation presupposes the doxastic recognition of reasons, and because infants lack the capacity to doxastically recognise reasons. But this choice seems to wrongly reduce the responses of infants to mere reflexes or instinctive reactions. On the other hand, doxasticists may choose a Humean route and deny (1) by espousing a purely causal or teleological account of motivation. But this would mean detrimentally ignoring the normative nature of (some instances of) motivation. -/- One elegant way of avoiding this dilemma is to give up doxasticism and instead endorse experientialism – the view that we enjoy some experiential access to reasons, which is independent of, and perhaps more fundamental than, our capacity to form normative judgements and beliefs. In this talk, I would like to provide an argument for the existence of such a non-doxastic form of access to reasons. More specifically, I aim to defend the claim that our basic awareness of reasons is phenomenal in nature. What this means is that it forms part of our access from the inside to those of our mental episodes that provide us with access to reasons. In other words, when we introspectively attend to reason-giving mental episodes and what they are about, we have the impression of the presence of a reason for us. My defence of this experientialist alternative to doxasticism will primarily focus on perceptual reasons for first-order beliefs about the external world. (shrink)

This text aims at presenting a general characterization of the act of perceiving a particular object, in a framework in which perception is conceived of as a mental and cognitive faculty having specific functions that other faculties such as imagination and memory do not possess. I introduce the problem of determining the occurrence of singular perception of a physical object, as opposed to the occurrence of other mental states or attitudes. I propose that clarifying this occurrence problem requires making explicit (...) the conditions of perceptual competence/faculty so as to explain the occurrence of each perceptual performance on the basis of the use of this competence. I argue then for a direct relational model according to which the singular perception of an object depends on a competence of connecting the perceiver directly with each target object. This model is compatible with a disjunctive approach to perception according to which each particular experience of an object corresponds either to a direct perceptual relation with this object or to the illusion of having the experience of this object. The arguments in favour of this relational model rest on the idea that the faculty of perception grounds the capacity to demonstratively identify physical objects. (shrink)

Part 1 of the thesis questions the traditional relation model of intentionality. After fixing reference on the target phenomenon, intentionality, and explaining my interest in it, I ask what sorts of things intentionality might be a relation to. I consider ordinary objects, properties, propositions and hybrid views, and conclude all make the intentional relation appear rather mysterious. From there, I move on to examine the relation view’s most prominent proponents, the tracking theorists—pointing out some challenges such views face, and concluding (...) that it might be worthwhile looking into alternatives to the relation view. Part 2 asks whether the newly emerging phenomenal intentionality movement can provide a viable alternative to the relation model of intentionality. After focusing on a specific kind of phenomenal intentionality theory—something I call modificationism—I examine three such accounts. From there I go on to discuss some common complaints/challenges these kinds of views face, and consider how they might be addressed within the modificationist framework. In Part 3, I address what I call the problem of cognitive contact: how do our contentful mental states manage to make cognitive contact with the ordinary objects (e.g. tables and chairs) that they appear to. The problem is particularly acute for any version of phenomenal intentionality that denies the relation view, and has been given very little attention in the literature. I consider how a modificationist might address this problem, and conclude that though some avenues appear promising, there is nevertheless a great deal of work to be done if modificationism, and phenomenal intentionality theory, is to overcome this problem.

This dissertation consists of three independent papers, each defending the Higher-Order Thought (HOT) Theory of Consciousness against a different objection. First the HOT theory is defended against the Theory of Mind (TOM) Objection. Since the HOT theory requires that a subject be able to represent mental states in thought in order to have mental states that are conscious, objectors argue from empirical evidence that few creatures pass TOM tests to the conclusion that few creatures must be capable of having conscious (...) mental states according to the HOT theory. The counter-intuitiveness of this claim is then taken as reason for rejecting the HOT theory. I argue that this objection is based on a false assumption - that the requirements of successful TOM test performance parallel the requirements outlined by the HOT theory. Since this assumption is false, we can reject the objection. In the second paper, I defend the HOT theory against the Phenomenal Character Argument. Objectors argue that the HOT theory must be rejected because it incorrectly characterizes the phenomenal character affiliated with basic state consciousness as necessarily involving a consciousness of the fact that one has a particular mental state. I argue that the theory cannot provide this characterization of phenomenal character because the theory cannot say that someone becomes conscious of what her unconscious HOTs represent. Since the objection rests on an incorrect interpretation of the theory, we can reject the objection. In the final paper, I defend the HOT theory against the Misrepresentation Objection. Here objectors accuse the HOT theory of presenting necessary and sufficient conditions for conscious states that turn out to be incompatible in empty HOT cases (cases wherein one’s HOT misrepresents the states one is instantiating). I argue that the conditions are actually each part of separate explanations of separate sorts of consciousness, that neither of the separate explanations has internally incompatible conditions, and hence that the objection is based on an equivocation on two senses of the phrase ‘conscious state’. Since the objection is based on this error, we can reject the objection. (shrink)

A widespread assumption in current philosophy of mind is that a conscious state’s phenomenal properties vary with its representational contents. In this paper, I present (rather dogmatically) an alternative picture that recognizes two kinds of phenomenal properties that do not vary concomitantly with content. First, it admits phenomenal properties that vary rather with attitude: what it is like for me to see rain is phenomenally different from what it is like for me to remember (indistinguishable) rain, which is different again (...) from what it is like for me to visualize (indistinguishable) rain – where these differences cannot be traced back to variations in content. Secondly, there is a kind of phenomenal property that varies neither with content nor with attitude but is altogether invariant across all conscious states: a substantive phenomenal commonality among what it is like for me to see, remember, and visualize rain, cats, or dogs. This substantive commonality, I will suggest, is the for-me-ness component of what it is like for me to have any of these experiences. I will close by discussing the interrelations among these three concentric layers of phenomenality: content-based, attitude-based, and for-me-ness. (shrink)

Consciousness fits uneasily into our conception of the natural world. On the most common conception of nature, the natural world is the physical world. But on the most common conception of consciousness, it is not easy to see how it could be part of the physical world. So it seems that to find a place for consciousness within the natural order, we must either revise our conception of consciousness, or revise our conception of nature. In twentieth-century philosophy, this dilemma is (...) posed most acutely in C. D. Broad’s The Mind and its Place in Nature . The phenomena of mind, for Broad, are the phenomena of consciousness. The central problem is that of locating mind with respect to the physical world. Broad’s exhaustive discussion of the problem culminates in a taxonomy of seventeen different views of the mental-physical relation.1 On Broad’s taxonomy, a view might see the mental as nonexistent , as reducible, as emergent, or as a basic property of a substance . The physical might be seen in one of the same four ways. So a four-by-four matrix of views results. At the end, three views are left standing: those on which mentality is an emergent characteristic of either a physical substance or a neutral substance, where in the latter case, the physical might be either emergent or delusive.

This article is devoted to the description of the experience associated with listening to a sound. In the first part, we describe the method we used to gather descriptions of auditory experience and to analyse these descriptions. This work of explicitation and analysis has enabled us to identify a threefold generic structure of this experience, depending on whether the attention of the subject is directed towards the event which is at the source of the sound, the sound in itself, considered (...) independently from its source, the felt sound. In the second part of the article, we describe this structure. The third part is devoted to a discussion of these results and the paths they open up in various fields of theoretical and applied research. (shrink)

This dissertation defends the reliability of first-person methods for studying consciousness, and applies first-person experiments to two philosophical problems: the experience of size and of the self. In chapter 1, I discuss the motivations for taking a first-person approach to consciousness, the background assumptions of the dissertation and some methodological preliminaries. In chapter 2, I address the claim that phenomenal judgements are far less reliable than perceptual judgements (Schwitzgebel, 2011). I argue that the main errors and limitations in making phenomenal (...) judgements are due to domain-general factors, which are shared in the formation of perceptual judgements. Phenomenal judgements may still be statistically less reliable than perceptual judgements, though I provide reasons for thinking that Schwitzgebel (2011) overstates the case for statistical unreliability. I also provide criteria for distinguishing between reliable and unreliable phenomenal judgements, hence defending phenomenal judgements against general introspective scepticism. Having identified the main errors in making phenomenal judgements, in chapter 3, I discuss how first-person experiments can be used to control for these errors. I provide examples, and discuss how they overcome attentional and conceptual errors, minimise biases, and exhibit high intersubjective reliability. In chapter 4, I investigate size experience. I use first-person experiments and empirical findings to argue that distant things looking smaller cannot be explained as an awareness of instantiated objective properties (visual angle or retinal image size). I also discuss how an awareness of uninstantiated objective properties cannot adequately account for the phenomenal character of size experience. This provides support for a subjectivist account of variance in size experience. In chapter 5, I investigate the sense of self. I distinguish between a weak sense of self (for-me-ness) and a strong sense of self in which there is a polarity between subject and object. I use first-person experiments from Douglas Harding to demonstrate an explicit strong sense of self, specifically when I point at where others see my face. I also argue that this sense of self is not explained by inference, thoughts, feelings, imagination nor the viewpoint. Rather, it is part of the structure of experience that I seem to be looking from here. Even if there is a sense of self, there may be no self. The question of chapter 6 is whether there can be a direct experience of the self. I argue that to function as a bearer of experience the subject must be single and lack sensory qualities in itself. I use Harding’s first-person experiments to investigate the visual gap where I cannot see my head. I argue that it conforms to the above criteria, and hence is a candidate for being the subject. This finding, in conjunction with the fact that I seem to be looking from the same location, provides prima facie evidence for the reality of the subject. I hold then that contrary to Hume and most philosophers since, that there can be a direct self-experience, if one knows which direction to attend. (shrink)

In this chapter, Pautz raises a puzzle about spatial experience for phenomenal internalists like Ned Block. If an accidental, lifelong brain-in-the-void (BIV) should have all the same experiences as you, it would have an experience as of items having various shapes, and be able to acquire concepts of those shapes, despite being cut off from real things with the shapes. Internalists cannot explain this by saying that BIV is presented with Peacocke-style visual field regions having various shapes, because these would (...) have to be non-physical sense data. They might instead explain this by saying that BIV “phenomenally represents” various shape properties. But since BIV lacks any interesting physical relations to shapes, this would imply that phenomenally representation is an irreducible relation. (shrink)

In “Radical Interpretation” (1974), David Lewis asked: by what constraints, and to what extent, do the non-intentional, physical facts about Karl determine the intentional facts about him? There are two popular approaches: the reductive externalist program and the phenomenal intentionality program. I argue against both approaches. Then I sketch an alternative multistage account incorporating ideas from both camps. If we start with Karl's conscious experiences, we can appeal to Lewisian ideas to explain his other intentional states. This account develops the (...) multistage Lewisian approach presented at the end of my earlier "Does Phenomenology Ground Mental Content?" (2013). (shrink)

O modelo causal de introspecção tem recebido muitas críticas e, de fato, nos últimos anos, tem caído em desuso no mundo filosófico. Neste artigo defendo o modelo e sustento que ele é um excelente candidato, dado um compromisso realista para com o mental, para explicar o nosso acesso introspectivo peculiar, mas contingente, às crenças.

By what empirical means can a person determine whether he or she is presently awake or dreaming? Any conceivable test addressing this question, which is a special case of the classical metaphysical doubting of reality, must be statistical (for the same reason that empirical science is, as noted by Hume). Subjecting the experienced reality to any kind of statistical test (for instance, a test for bizarreness) requires, however, that a set of baseline measurements be available. In a dream, or in (...) a simulation, any such baseline data would be vulnerable to tampering by the same processes that give rise to the experienced reality, making the outcome of a reality test impossible to trust. Moreover, standard cryptographic defenses against such tampering cannot be relied upon, because of the potentially unlimited reach of reality modification within a dream, which may range from the integrity of the verification keys to the declared outcome of the entire process. In the face of this double predicament, the rational course of action is to take reality at face value. The predicament also has some intriguing corollaries. In particular, even the most revealing insight that a person may gain into the ultimate nature of reality (for instance, by attaining enlightenment in the Buddhist sense) is ultimately unreliable, for the reasons just mentioned. At the same time, to adhere to this principle, one has to be aware of it, which may not be possible in various states of reduced or altered cognitive function such as dreaming or religious experience. Thus, a subjectively enlightened person may still lack the one truly important piece of the puzzle concerning his or her existence. (shrink)

I defend a theory of mental representation that satisfies naturalistic constraints. Briefly, we begin by distinguishing (i) what makes something a representation from (ii) given that a thing is a representation, what determines what it represents. Representations are states of biological organisms, so we should expect a unified theoretical framework for explaining both what it is to be a representation as well as what it is to be a heart or a kidney. I follow Millikan in explaining (i) in terms (...) of teleofunction, explicated in terms of natural selection. -/- To explain (ii), we begin by recognizing that representational states do not have content, that is, they are neither true nor false except insofar as they both “point to” or “refer” to something, as well as “say” something regarding whatever it is they are about. To distinguish veridical from false representations, there must be a way for these separate aspects to come apart; hence, we explain (ii) by providing independent theories of what I call f-reference and f-predication (the ‘f’ simply connotes ‘fundamental’, to distinguish these things from their natural language counterparts). -/- Causal theories of representation typically founder on error, or on what Fodor has called the disjunction problem. Resemblance or isomorphism theories typically founder on what I’ve called the non-uniqueness problem, which is that isomorphisms and resemblance are practically unconstrained and so representational content cannot be uniquely determined. These traditional problems provide the motivation for my theory, the structural preservation theory, as follows. F-reference, like reference, is a specific, asymmetric relation, as is causation. F-predication, like predication, is a non-specific relation, as predicates typically apply to many things, just as many relational systems can be isomorphic to any given relational system. Putting these observations together, a promising strategy is to explain f-reference via causal history and f-predication via something like isomorphism between relational systems. -/- This dissertation should be conceptualized as having three parts. After motivating and characterizing the problem in chapter 1, the first part is the negative project, where I review and critique Dretske’s, Fodor’s, and Millikan’s theories in chapters 2-4. Second, I construct my theory about the nature of representation in chapter 5 and defend it from objections in chapter 6. In chapters 7-8, which constitute the third and final part, I address the question of how representation is implemented in biological systems. In chapter 7 I argue that single-cell intracortical recordings taken from awake Macaque monkeys performing a cognitive task provide empirical evidence for structural preservation theory, and in chapter 8 I use the empirical results to illustrate, clarify, and refine the theory.

My main aim is to clarify what we mean by ‘look’ sentences such as (1) below – ones that we use to talk about visual experience: -/- (1) The ball looked red to Sue -/- This is to help better understand a part of natural language that has so far resisted treatment, and also to help better understand the nature of visual experience. -/- By appealing to general linguistic principles I argue for the following account. First, we use (1) to (...) talk about an event. Second, we use the verb ‘look’ to specify the kind of event about which we are talking – it is a looking event. Third, we use the subject ‘the ball’ to specify a stimulus of the event – something that looks some way in the event. Fourth, we use the adjunct ‘to Sue’ to specify an experiencer of the event – someone to whom things look some way in the event. Finally, we use the complement ‘red’ to specify a way of the event – a way in which the event occurs (I take ways of occurring to be properties of events). Which way do we use ‘red’ in (1) to specify? I argue: the maximally specific way w such that the following is generically true: looking events whose stimulus is red occur in way w (it is important that this is understood generically: this is what does much of the work in explaining our use of (1) and other ‘look’ sentences). Putting this together, what we mean by (1) is: there was a looking event whose stimulus was the ball, whose experiencer was Sue, and which occurred in the maximally specific way that looking events occur when their stimulus is red. -/- This account of how we use ‘red’ in (1) is one of the most interesting aspects of my thesis. It extends to an account of how we use ‘proud’ in ‘John walks proud’, ‘as if he is American’ in ‘John talks as if he is American’, ‘like a duck’ in ‘John sounds like a duck’, and so on. In each case we use the expression in question to specify a way: the maximally specific way proud people walk, the maximally specific way American people talk, and so on. So the study of ‘look’ sentences has much to tell us about the functioning of many other English language constructions, and suggests that ways have a significant role to play in the semantics of natural language – a fact that has not yet been sufficiently recognised by linguists or philosophers of language. -/- My thesis also has implications for the philosophy of perception. One of the central questions about perception is: What is the nature of visual experience? What is it, for example, for a ball to look red to Sue? My thesis offers an answer: What it is for the ball to look red to Sue is for whatever it is that we mean by ‘The ball looks red to Sue’ to be the case, and what we mean by ‘The ball looks red to Sue’ is that there is a looking event whose stimulus is the ball, whose experiencer is Sue, and which is occurring in a certain way. It thus delivers an adverbial account of visual experience, one that has the resources to better deal with problems that are traditionally thought to be decisive against adverbial accounts. (shrink)

This paper examines the epistemic status of the reflective belief about the content of one’s own conscious mental state, with emphasis on perceptual experience. I propose that the process that gives a special epistemic status to a reflective belief is not observation, inference, or conceptual articulation, but semantic ascent similar to the transition from a sentence in the object language to a sentence in the meta-language that affirms the truth of the original sentence. This account of the process of reflection (...) explains why a reflective belief is (subject to some qualification) infallible. (shrink)

Here I present a sympathetic but critical analysis of Damasio's latest book. I begin with a brief exposition of his neurobiological theory of emotion and then take issue with him on the cognitive and representational nature of emotional states. I discuss his view of consciousness as a second-order set of neural activations, which are allegedly intimately related to, and even necessary for, elementary emotional and homeodynamic processes. I find Damasio's account wanting in at least two respects. First, the relationship between (...) emotional states and the consciousness thereof is left ambiguous. Second, Damasio lacks a clear psychological hypothesis about the hierarchy of first-, second-, and possibly third-order mental/neural states. The result is that a wealth of neurobiological information fails to be organized in a coherent conceptual scheme, and the whole account is ultimately unsatisfactory. (shrink)

Our conscious experiences are said to possess a unique property called phenomenal consciousness. Why these and only these states of us have this property has proved to be an exceedingly difficult question for philosophers and scientists to answer. In fact, some have claimed that this question constitutes the hard problem of the mind-body problem, one which cannot be solved by the standard methods of contemporary science. In his most recent book, Phenomenal Consciousness, Peter Carruthers offers a bold, original and scientifically (...) acceptable solution to this hard problem: the dispositional higher-order thought theory. I describe the main line of argument in Phenomenal Consciousness for Carruthers' dispositional HOT theory and present three places where the argument seems most vulnerable. I end the review with a very positive endorsement of Phenomenal Consciousness, recommending it as compulsory reading for anyone interested in the contemporary philosophical and scientific debate over the nature of phenomenal consciousness.

Chapter 1 is devoted to taking care of some preliminary issues. I begin by distinguishing those states of awareness in virtue of which we’re acquainted with the phenomenal characters of our experiences from those states of awareness some claim are at the very nature of experience. Then I reconcile the idea that experience is transparent with the claim that we can be acquainted with phenomenal character. -/- In Chapter 2 I set up a dilemma that is the primary focus of (...) the dissertation. In the first part of this chapter I argue that phenomenal acquaintance has three key features, what I call its ‘directness’, ‘thickness’, and ‘infallibility’. In the second part I argue, however, that it’s really quite puzzling how thoughts about phenomenal character (or any thoughts, for that matter) could have them. In the next two chapters I consider how we might resolve the dilemma described above. -/- I begin in Chapter 3 by considering an account of phenomenal acquaintance inspired by Bertrand Russell’s discussion of acquaintance. The general idea here is to excise mental representation from phenomenal acquaintance, and I ultimately reject the proposal. -/- Chapter 4 is the core chapter of the dissertation. In it I propose an account of phenomenal acquaintance that doesn’t excise mental representation. My account is comprised of three theses. First, token experiences are complex and have instances of phenomenal properties as components. Second, instances of phenomenal properties are mental representations, and they represent themselves. Third, the attention relevant to phenomenal acquaintance is underwritten by self-representation. I argue that my account explains how phenomenal acquaintance is direct, thick, and infallible, thereby resolving our dilemma. -/- I argue in Chapter 5 that my account of phenomenal acquaintance explains why there is an explanatory gap between the phenomenal and non-phenomenal truths. Accordingly, I conclude that the explanatory gap doesn’t pose a problem for physicalism. Here I implement what has come to be called the ‘phenomenal concept strategy’ for responding to the challenge posed by the explanatory gap. (shrink)

This paper overviews the current status of debates on tracking representationalism, the view that phenomenal consciousness is a matter of tracking features of one's environment in a certain way. We overview the main arguments for the view and the main objections and challenges it faces. We close with a discussion of alternative versions of representationalism that might overcome the shortcomings of tracking representationalism.

Higher-Order Representational theories of consciousness — HORs — primarily seek to explain a mental state’s being conscious in terms of the mental state’s being represented by another mental state. First-Order Representational theories of consciousness — FORs — primarily seek to explain a property’s being phenomenal in terms of the property being represented in experience. Despite differences in both explanans and explananda, HORs and FORs share a reliance on there being such a property as being represented. In this paper I develop (...) an argument — the Unicorn Argument — against both HORs and FORs. The core of the Unicorn is that since there are mental rep- resentations of things that do not exist, there cannot be any such prop- erty as being represented, and thus no such property with which to identify either being conscious or being phenomenal.

This chapter analyzes aspects of the relationship between consciousness and intentionality. It focuses on the phenomenal character and the intentional content of perceptual states, canvassing various possible relations among them. It argues that there is a good case for a sort of representationalism, although this may not take the form that its advocates often suggest. By mapping out some of the landscape, the chapter tries to open up territory for different and promising forms of representationalism to be explored in the (...) future. In particular, it argues for a nonreductive, narrow, and Fregean variety of representationalism, which contrasts strongly with more widely explored varieties. It concludes with some words about the fundamental relationship between consciousness and intentionality. (shrink)

Evolutionary explanations of psychological phenomena have become widespread. This paper examines a recent attempt by Nichols and Grantham (2000) to circumvent the problem of epiphenomenalism in establishing the selective status of consciousness. Nichols and Grantham (2000) argue that a case can be made for the view that consciousness is an adaptation based on its complexity. I set out this argument and argue that it fails to establish that phenomenal consciousness is a complex system. It is suggested that the goal of (...) establishing consciousness as an adaptation may be better served by rejecting the distinction between access consciousness and phenomenal consciousness.

Before one can even begin to model consciousness and what exactly it means that it is a subjective phenomenon one needs a theory about what a first-person perspective really is. This theory has to be conceptually convincing, empirically plausible and, most of all, open to new developments. The chosen conceptual framework must be able to accommodate scientific progress. Its ba- sic assumptions have to be plastic as it were, so that new details and empirical data can continuously be fed into (...) the theoretical model as it grows and becomes more refined. This paper makes an attempt at sketching the outlines of such a theory, offering a representationalist analysis of the phenomenal first-person perspective. Three phenomenal target properties are centrally relevant. (shrink)
