Some mental states are about themselves. Nothing is a cause of itself. So some mental states are not about their causes; they are about things distinct from their causes. If this argument is sound, it spells trouble for causal theories of mental content—the precise sort of trouble depending on the precise sort of causal theory. This paper shows that the argument is sound (§§1-3), and then spells out the trouble (§4).

This dissertation argues that mental representation is identical to phenomenal consciousness, and everything else that appears to be both mental and a matter of representation is not genuine mental representation, but either in some way derived from mental representation, or a case of non-mental representation.

Integrated information theory is a theory of consciousness that was originally formulated, and is standardly still expressed, in terms of controversial interpretations of its own ontological and epistemological basis. These form the orthodox interpretation of IIT. The orthodox epistemological interpretation is the axiomatic method, whereby IIT is ultimately derived from, justified by, and beholden to a set of phenomenological axioms. The orthodox ontological interpretation is panpsychism, according to which consciousness is fundamental, intrinsic, and pervasive. In this paper it is argued (...) that both components of the orthodox interpretation should be rejected. But IIT should not be rejected since an interpretation-neutral formulation is available. After explaining the neutral formulation, more plausible non-axiomatic epistemologies are defended. The neutral formulation is then shown to be consistent with various contemporary physicalist ontologies of consciousness, including the phenomenal concept strategy, representationalism, and even illusionism. Along the way, instructive connections between interpretations of IIT and interpretations of quantum mechanics are noted. (shrink)

This paper exploits the fact that the variability in the inter-spike intervals, in the spike train issuing from a neuron, carries substantial information regarding the input to the neuron. A framework for neuronal information processing is proposed which utilizes the above fact to distinguish phenomenal from non-phenomenal mental representation. In the process, an explanation is offered as to what is it, in the nature of conscious mental states, that imparts them a subjective feeling – there is something it is like (...) to be in those mental states. To give empirical support, it is shown how the proposed framework can neatly explain, the delay in eliciting conscious awareness as observed by Libet and the related backwards referral in time.

Annotated bibliography of works on externalism and internalism in the philosophy of mind.

I propose that there are two kind's of qualia realism, and that Harman's observations about the transparency of experience pose a threat to only one of these.

Naïve realism, often overlooked among philosophical theories of perception, has in recent years attracted a surge of interest. Broadly speaking, the central commitment of naïve realism is that mind-independent objects are essential to the fundamental analysis of perceptual experience. Since the claims of naïve realism concern the essential metaphysical structure of conscious perception, its truth or falsity is of central importance to a wide range of topics, including the explanation of semantic reference and representational content, the nature of phenomenal consciousness, (...) and the basis of perceptual justification and knowledge. One of the greatest difficulties surrounding discussions of naïve realism, however, has been lack of clarity concerning exactly what affirming or denying it entails. In particular, it is sometimes unclear how naïve realism is related to the claim that perceptual experience is in some sense direct or unmediated, and also to what extent the view is compatible with another widely discussed thesis in the philosophy of perception, the claim that perceptual experiences are states with representational content. In this essay, I discuss how recent work on these issues helps to clarify both the central commitments of naïve realism, as well as its relation to representationalist theories of perception. Along the way, I will attempt to shed light on the different ways in which each approach tries to address the various theoretical challenges facing a philosophical theory of perception, and also to assess the prospects for views that attempts to combine features of each approach.

Discourse containing the verb ‘feel’, almost without exception, purports to describe inner experience. Though this much is evident, the question remains what exactly is conveyed when we talk about what and how we feel? Does discourse containing the word ‘feel’ actually succeed in describing the content and phenomenology of inner experience? If so, how does it reflect the phenomenology and content of the experience it describes? Here I offer a linguistic analysis of ‘feels’ reports and argue that a subset of (...) ‘feels’ reports, when accurate, reflect the representational content of emotions, tactile experiences and bodily sensations. Because ‘feels’ reports may reflect the representational content of bodily experience, these types of report may be able to give us some insight into the structure of bodily experience. I argue that our descriptions of bodily experience, on the assumption that they are sometimes accurate, indicate that emotions and tactile experiences are experiences of bodily reactions to objects, whereas bodily sensations are partial descriptions of emotions and tactile experiences or other events of the body. At the end I address the concern that an adequate account of inner experience cannot be given in terms of an analysis of ordinary language. (shrink)

Most people find it obvious that concepts like APPLE, DOG, WATER, CACTUS, SWIM, CHIRP, FURRY, and SMOOTH are acquired from perceptual experiences along with some kind of inferential procedure. Models of how these concepts are inferentially acquired, however, force the acquired concepts to be representationally complex, built from, and composed by, the more primitive representations. Since at least the time of Plato, philosophers and psychologists have struggled to find complex sets of representations that have the same meanings, definitionally or probabilistically, (...) as these concepts. For example, to think about the property-kind being gold is not the same as to think about the complex property-kind being yellowish & shiny & malleable.... I call this Fodor's Challenge: Find an acquisition process that is genuinely inferential and yields a concept that genuinely is one of these lexical concepts. Rather than continue the pursuit of a complex representation that has the same meaning as our concept GOLD. I offer a model on which many lexical concepts are acquired from perception and inference, without being built up from, and composed by, the representations involved. The model, Baptizing Meanings for Concepts, is inspired in part by Saul Kripke's baptism process for assigning meanings to linguistic terms. Many lexical concepts, according to the BMC, are acquired by inferring the presence a new property-kind, picking out the property-kind in terms of those perceptible features, and then assigning a simple mental term, a concept, for that property-kind.

Imagine slicing your hand with a steak knife. Inevitably, this leads to a characteristic unpleasant sensation, and just as reliably, to a withdrawal of the wounded limb. But can this rather mundane fact--and other similar facts--shed any light on the mind-body problem or the issue of the role of experience in causing behavior? In my dissertation, I explore this issue head on, and in the process clarify and criticize the arguments of philosophers who have given an affirmative answer to this (...) question--philosophers such as William James and Herbert Spencer. These arguments have coupled evidence like the above with the fact that human beings have evolved, in order to make the case that epiphenomenalism with respect to qualia is false. My first task will be to formulate a rigorous version of a James-Spencer style argument, which will occupy us in Chapter 1. Chapter 2 is dedicated to answering a number of objections to the argument, in an effort to show that if there is a problem with it, this problem lies elsewhere. Chapter 3 explores alternative arguments in the spirit of the original one formulated in Chapter 1, and discusses any resulting effects on the plausibility of the conclusion. Chapter 4 is the capstone chapter of the dissertation. In it, I discuss a crucial objection to all arguments in the spirit of that given in the first chapter--namely, that physicalism has analogous flaws to epiphenomenalism where accommodating the relevant evidence is concerned. My conclusions in this final chapter are twofold. First, that even if there is no fatal flaw in the general strategy the evolutionary argument employs, it works against all forms of dualism, not just epiphenomenalism. And second, the accusations made in the objection are correct; physicalism suffers from problems analogous to those faced by epiphenomenalism. Although the primary findings of the dissertation are negative, there are many lessons we can take from them along the way. Most prominent among them is an improved perspective on the appropriate roles of empirical findings and armchair philosophical theorizing in debate over the mind-body problem. (shrink)

From the first-person point of view, seeing a red square is very different from thinking about a red square, hearing an alarm sound is very different from thinking that an alarm is sounding, and smelling freshly-roasted coffee is very different from thinking that there is freshly-roasted coffee in one’s vicinity. How might the familiar contrast between representing a fact in thought and representing it in perception be captured? One influential idea is that perceptual states are phenomenally conscious whereas thoughts are (...) not. However, those theorists who hold that thoughts have a distinctive kind of phenomenal character – often known as “cognitive phenomenology” – cannot account for the contrast between thought and perception in this manner. This paper examines the various options that are available to advocates of cognitive phenomenology for capturing the experiential contrast between thought and perception, and argues that each of them faces serious challenges.

The thesis is intended to contribute to the growing understanding of the indispensable role played by phenomenal consciousness in human cognition, and specifically in making our concepts of the external world available. The focus falls on so called observational concepts, a type of rudimentary, perceptually-based objective concepts in our repertoire — picking out manifest properties such as colors and shapes. A theory of such concepts gets provided, and, consequently, the exact role that perceptual consciousness plays in making concepts of this (...) sort available gets settled. In the first half of the thesis, observational concepts get construed as a special type of recognitional concepts. On an analogy with perceptual demonstratives, having such concepts would involve having non-trivial knowledge of their reference. The experiential basis of such concepts would, among other things, provide for such constitutive knowledge. The theoretical background relevant to the hypothesis gets provided in the first chapter. A defence of the hypothesis follows in the second. In the second half of the thesis, care is taken to distinguish among two ways in which the constitutive knowledge of the reference of an observational concept could be fleshed out. In the third chapter, perceptual experience is shown to provide the basis both for knowledge of observational properties by acquaintance, and for knowledge of the essence of such properties — provided that knowledge of essence gets construed in the right, modest way. It might be natural to take knowledge by acquaintance to be the sort relevant to observational concept possession, especially given that in the case of perceptual demonstratives this is the role likely played by experience. However, this initial impression proves to be mistaken. The constitutive knowledge of the referent of an observational concept turns out to consist in the capacity to determine a priori the essence of the respective property. To show this, an argument gets provided in the penultimate fourth chapter, based on the key role played by experiences of instances of observational properties in optimal viewing conditions in enabling the possession of the respective observational concept.

Relationalism claims that the phenomenal character of perception is constituted by the obtaining of a non-representational psychological relation to mind-independent objects. Although relationalism provides what seems to be the most straightforward and intuitive account of how experience strikes us introspectively, it is very often believed that the argument from hallucination shows that the view is untenable. The aim of this thesis is to defend relationalism against the argument from hallucination. The argument claims that the phenomenal character of hallucination and perception (...) deserves the same account, and that relationalism cannot be true for hallucinations, therefore relationalism must be rejected. This argument relies on the Indiscriminability Principle, the claim that two experiences that are introspectively indiscriminable from each other have the same phenomenal character. Before assessing the plausibility of this principle, I first consider and dismiss versions of the argument which wouldn’t depend on IND. Although widely accepted, no satisfactory support for IND has been presented yet. In this thesis I argue that defending IND requires that we understand the notion of ‘indiscriminability’ employed in IND in an impersonal sense. I then identify what underwrites IND: the intuition that, in virtue of its superficiality, the nature of a phenomenal character must be accessible through introspection, together with the claim that it is not possible to deny IND without denying the superficiality of phenomenal characters too. I argue that the relationalist can deny IND while preserving the superficiality of phenomenal characters. This can be done by adopting a negative view of hallucination and an account of introspection whereby the phenomenal character doesn’t exist independently of one’s introspective awareness of it and where having introspective access to our experience depends on our perceptual access to the world.

Does synesthesia undermine representationalism? Gregg Rosenberg (2004) argues that it does. On his view, synesthesia illustrates how phenomenal properties can vary independently of representational properties. So, for example, he argues that sound/color synesthetic experiences show that visual experiences do not always represent spatial properties. I will argue that the representationalist can plausibly answer Rosenberg.

Rosenberg’s general argumentative strategy in favour of panpsychism is an extension of a traditional pattern. Although his argument is complex and intricate, I think a model that is historically significant and fundamentally similar to the position Rosenberg advances might help us understand the case for panpsychism. Thus I want to begin by considering a Leibnizian argument for panpsychism.

When you look at a circular plate at an angle, it looks circular. But there also is a certain sense in which its look can be described as oval. When you move, the plate’s look changes with your perspective on it—nevertheless, it continues to look circular. This chapter investigates whether these “constancy in variation” phenomena can be explained in terms of the representational content of visual experience, and whether constancy in variation provides special, phenomenological, reasons to construe experience as having (...) centered contents. Concentrating on shape, it argues that due to warring phenomenological demands, all views construing constancy in variation as representation of both objective and perspectival properties or features have limited explanatory powers, and that centering does not provide any advantage. By contrast, adopting the non-standard intentionalism called phenomenal intentionalism, we get rather natural explanations of the phenomenology of constancy in variation. (shrink)

This dissertation examines representationalism about sensory phenomenology—the claim that for a sensory experience to have a particular phenomenal character is a matter of it having a particular representational content. I focus on a particular issue that is central to representationalism: whether reductive versions of the theory should be internalist or externalist. My primary goals are to demonstrate that externalist representationalism fails to provide a reductive explanation for phenomenal qualities, and to present a reductive internalist version of representationalism that utilizes the (...) empirical framework of psychophysics and neuroscience to develop a philosophical theory of content. The bulk of the project is an attempt to provide the outlines of what such an empirically-based representationalist theory would look like. In chapter 2, I argue that reductive externalist representationalism fails because it is vulnerable to the problem of bad structural correlation: the mismatch between the structure of phenomenal qualities and the structure of physical properties “tracked” by our sensory systems with which phenomenal qualities are identified. In chapter 3, I develop the outlines of a reductive internalist version of representationalism that characterizes phenomenal qualities as modes of presentation of sensory representations that can be reductively characterized in terms of a location in a psychophysically-defined quality space, which can in turn be given a neurophysiological interpretation. In addition, I argue that the neural mechanisms responsible for the representation of spatial locations and visual objects serve a referential role in sensory psychosemantics that grounds the intentionality of sensory states. In chapter 5 I provide a detailed account of the representation of spatial locations in sensory experience, and in chapter 6 I examine the “binding problem”, demonstrating how object-based sensory representations function to demonstratively pick out sensory individuals without explicitly representing any of their features. I describe the resulting view as methodological representationalism: an attempt to demonstrate how a particular philosophical theory of sensory phenomenology can be integrated into the empirical framework of cognitive science, and thereby provide an explanatory psychosemantic framework for sensory phenomenology that is valuable to both philosophers and cognitive scientists.

The purpose of this paper is to defend and further develop an account of the phenomenal character of perceptual experience. Rather than identify the phenomenal character with the intrinsic properties represented by perceptual experience (phenomenal externalism), my aim is to support the alternative claim that the phenomenal character of a perceptual experience is to be identified with the mode of presentation of environmental properties.

We maintain that no extant argument in favor of phenomenal external- ism is really convincing. PE is the thesis that the phenomenal properties of our experiences must be individuated widely insofar as they are constituted by worldly properties. We consider what we take to be the five best arguments for PE. We try to show that none of them really proves what it aims at proving. Unless better arguments in favor of phenomenal externalism show up in the debate, we see (...) no reason to relinquish an idea that seems intuitive and appeals to many cognitive sci- entists: that phenomenology is narrow, i.e., that phenomenal properties are intrinsic properties of our experiences. This idea grounds the opposite philosophical position, phenomenal internalism. (shrink)

I argue for a manipulationist-mechanistic framework for content-NCC research in the case of visual consciousness (Bechtel 2008; Neisser 2012). Reference to mechanisms is common in the NCC research. Furthermore, recent developments in non-invasive brain stimulation techniques (NIBS) lend support to a manipulationist standpoint. The crucial question is to understand what is changed after manipulation of a brain mechanism. In the second part of the paper I review the literature on intentionalism, and argue that intervention on the neural mechanism is likely (...) to change the intentional content of consciousness. This urges us to shift from content-NCC to what I call “intentional mechanisms”. Such mechanisms, it is argued, should be understood as neural prerequisites of conscious visual experience. (shrink)

Argues for a failure of correspondence between perceptual representation and what it is like to perceive. If what it is like to perceive is grounded in perceptual representation, then, using considerations of veridical representation, we can show that inattentive peripheral perception is less representationally precise than attentive foveal perception. However, there is empirical evidence to the contrary. The conclusion is that perceptual representation cannot ground what it is like to perceive.

The phenomenal particularity thesis says that if a mind-independent particular is consciously perceived in a given perception, that particular is among the constituents of the perception’s phenomenology. Martin, Campbell, Gomes and French and others defend this thesis. Against them are Mehta, Montague, Schellenberg and others, who have produced strong arguments that the phenomenal particularity thesis is false. Unfortunately, neither side has persuaded the other, and it seems that the debate between them is now at an impasse. This paper aims to (...) break through this impasse. It argues that we have reached the impasse because two distinct conceptions of phenomenology—a “narrow” conception and a “broad” conception—are compatible with our what-it-is-like characterizations of phenomenology. It also suggests that each of these two conceptions has its own theoretical value and use. Therefore, the paper recommends a pluralistic position, on which we acknowledge that there are two kinds of phenomenology: narrow phenomenology and broad phenomenology. The phenomenal particularity thesis is true only with respect to the latter. (shrink)

The aim of this thesis is to provide a theory of phenomenal consciousness which accords with both the science-friendly spirit of physicalism and the acknowledgement of panpsychism that phenomenal properties may be inextricably linked to entities, but with none of the problems associated with either type of model. Initially, physicalism and panpsychism are evaluated by the lights of their most serious problems, and solutions are offered to these problems from the point of view of a third kind of model: intrinsic (...) naturalism, presented in the final chapter. This model holds consciousness to be among the battery of a functional system’s intrinsic properties. A definition is given, and defence made for the existence of these properties, and their compatibility with an otherwise physicalist ontology. (shrink)

Jane’s fleeting glimpse of a mockingbird conscious is Jane’s taking a perspective on, or representing, that glimpse; or one might say that the specific feel of that fleeting glimpse can be understood by saying how things are from Jane’s perspective, or how Jane represented things to be (it was to Jane as if a mockingbird flashed by).
