The purpose of this paper is to address a well-known dilemma for physicalism. If mental properties are type identical to physical properties, then their causal efficacy is secure, but at the cost of ruling out mentality in creatures very different to ourselves. On the other hand, if mental properties are multiply realizable, then all kinds of creatures can instantiate them, but then they seem to be causally redundant. The causal exclusion problem depends on the widely held principle that realized properties (...) inherit their causal powers from their realizers. While this principle holds for functional realization, it fails on a broader notion of realization that permits the realization of complex qualitative properties such as spatial and temporal patterns. Such properties are best seen as dependent powerful qualities, which have their causal roles in virtue of being the qualities they are, and do not inherit powers from their realizers. Recent studies have identified one such property—neural synchrony—as a correlate of consciousness. If synchrony is also partially constitutive of consciousness, then phenomenal properties are both multiply realizable and causally novel. I outline a version of representationalism about consciousness on which this constitution claim holds. (shrink)

Normal perception involves conscious experience of the world. What I call the Content View, (CV), attempts to account for this in terms of the representational content of perception (Brewer, 2011, esp. ch. 4). I offer a new argument here against this view. Ascription of personal level content, either conceptual or nonconceptual, depends on the idea that determinate predicational information is conveyed to the subject. This determinate predication depends upon the exercise of certain personal level capacities for categorization and discrimination. Exercise (...) of such personal level capacities depends in turn upon conscious selective attention. Yet conscious visual acquaintance with the world is the prior ground for the possibility of any such conscious selective attention. Acquaintance obtains throughout the visual field: where conscious attention is not actually directed as well as where it is. So acquaintance does not depend upon conscious selective attention. Thus, acquaintance is not sufficient for the exercise of the relevant personal level capacities. Exercise of these capacities is nevertheless necessary for personal level content. Therefore visual acquaintance cannot be understood in terms of perceptual content: basic conscious experience of the world is not a matter of anything like the predication involved in perceptual content. It is rather the relational ground for the possibility of such predication. (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). (shrink)

I use an old challenge to motivate a new view. The old challenge is due to variation in our perceptions of secondary qualities. The challenge is to say whose perceptions are accurate. The new view is about how we manage to perceive secondary qualities, and thus manage to perceive them accurately or inaccurately. I call it perceptual structuralism. I first introduce the challenge and point out drawbacks with traditional responses. I spend the rest of the paper motivating and defending a (...) structuralist response. While I focus on color, both the challenge and the view generalize to the other secondary qualities. (shrink)

Intermodal representationalists hold that the phenomenal characters of experiences are fully determined by their contents. In contrast, intramodal representationalists hold that the phenomenal characters of experiences are determined by their contents together with their intentional modes or manners of representation, which are nonrepresentational features corresponding roughly to the sensory modalities. This paper discusses a kind of experience that provides evidence for an intermodal representationalist view: intermodal experiences, experiences that unify experiences in different modalities. I argue that such experiences are much (...) easier to explain on the intermodal view. (shrink)

Bertrand Russell [1912] argued that we are acquainted with our experiences. Although this conclusion has generated a lot of discussion, very little has been said about Russell's actual arguments for it. This paper aims to remedy that. I start by spelling out two Russellian arguments for acquaintance. Then I show that these arguments cannot both succeed. For if one is sound, the other isn't. Finally, I weigh our options with respect to these arguments, and defend one option in particular. I (...) argue that we have good reason to believe that we can be, and sometimes are, acquainted with our experiences. (shrink)

This review provides an overview of Eva Schmidt's impressively thorough and detailed book on the Conceptualist/Nonconceptualist debate in the philosophy of perception, and briefly sketches two objections to Schmidt. First, I suggest that a certain dilemma for the Conceptualist Schmidt raises in the context of her discussion of the fineness of grain argument is surmountable. Second, I question whether Schmidt's response to the epistemological motivation for Conceptualism is sound.

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.

To believe is to possess a wide variety of dispositions pertinent to the proposition believed. Among those dispositions are self-ascriptive dispositions. Consequently, being disposed to self-ascribe belief that P is partly constitutive of believing that P. Such self-ascriptive dispositions can be underwritten by any of a variety of mechanisms, acting co-operatively or competitively. But since self-ascriptive dispositions are only partly constitutive of belief, there can be cases in which the self-ascriptive dispositions splinter away from the remaining dispositions. It is then (...) an empirical question how often our self-ascriptive dispositions diverge from the remaining dispositions constitutive of belief. The dispositions will tend to align reliably when possession of the belief in question is normatively neutral, straightforwardly connected to behavior, and most centrally manifested in explicit assertions or judgments. When these three conditions are not met, self-ascription, self-conscious avowal, sincere utterance, and explicit judgment will often diverge from the various other dispositions constitutive of belief. Even self-knowledge of explicit judgment can be problematic when we are attracted to half-empty forms of words or when we are not entirely persuaded of what we are saying. (shrink)

I distinguish two ways of explaining our capacity for ‘transparent’ knowledge of our own present beliefs, perceptions, and intentions: an inferential and a reflective approach. Alex Byrne (2011) has defended an inferential approach, but I argue that this approach faces a basic difficulty, and that a reflective approach avoids the difficulty. I conclude with a brief sketch and defence of a reflective approach to our transparent self-knowledge, and I show how this approach is connected with the thesis that we must (...) distinguish between a kind of self-knowledge that is of oneself as agent and another kind that is of oneself as patient.

According to the phenomenal intentionality research program, a state’s intentional content is fixed by its phenomenal character. Defenders of this view have little to say about just how this grounding is accomplished. I argue that without a robust account of representation, the research program promises too little. Unfortunately, most of the well-developed accounts of representation – asymmetric dependence, teleosemantics, and the like – ground representation in external relations such as causation. Such accounts are inconsistent with the core of the phenomenal (...) intentionality program. I argue that, however counter-intuitive it may seem, the best prospect for explaining how phenomenal character represents appeals to resemblance. (shrink)

It’s a familiar fact that there is something it is like to see red, eat chocolate or feel pain. More recently philosophers have insisted that in addition to this objectual phenomenology there is something it is like for me to eat chocolate, and this for-me-ness is no less there than the chocolatishness. Recognizing this subjective feature of consciousness helps shape certain theories of consciousness, introspection and the self. Though it does this heavy philosophical work, and it is supposed to be (...) relatively obvious to anyone who introspects, it is rather difficult to see just what this phenomenal me-ness is supposed to be; indeed, many philosophers deny it exists. In this paper we try to provide a clear sense of what phenomenal me-ness involves, and then then consider some arguments for the existence of phenomenal me-ness experience as well as some accounts of what gives rise to it. In the end, we argue that the plausible senses of me-ness are a good deal thinner than what often seems to be claimed. (shrink)

Color relationalism holds that the colors are constituted by relations to subjects. The introspective rejoinder against this view claims that it is opposed to our phenomenally-informed, pre-theoretic intuitions. The rejoinder seems to be correct about how colors appear when looking at how participants respond to an item about the metaphysical nature of color but not when looking at an item about the ascription of colors. The present article expands the properties investigated to sound and taste and inspects the mentioned asymmetry, (...) with a particular focus on the principle of charity. Using a metaphysical item, we find that color and sound are no different from shape, our control for a clearly anti-relational property. Taste, on the other hand, is no different from likability, our control for a clearly relational property. Importantly, we find that the disparity between metaphysical and ascription items is due to participants using a principle of charity to interpret disagreement cases such that both parties can be correct.

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.

Call the idea that states of perceptual awareness have intentional content, and in virtue of that aim at or represent ways the world might be, the ‘Content View.’ I argue that though Kant is widely interpreted as endorsing the Content View there are significant problems for any such interpretation. I further argue that given the problems associated with attributing the Content View to Kant, interpreters should instead consider him as endorsing a form of acquaintance theory. Though perceptual acquaintance is controversial (...) in itself and in attribution to Kant, it promises to make sense of central claims within his critical philosophy. (shrink)

Propositional attitudes are often classified as non-phenomenal mental states. I argue that there is no good reason for doing so. The unwillingness to view propositional attitudes as being essentially phenomenal stems from a biased notion of phenomenality, from not paying sufficient attention to the idioms in which propositional attitudes are usually reported, from overlooking the considerable degree to which different intentional modes can be said to be phenomenologically continuous, and from not considering the possibility that propositional attitudes may be transparent, (...) just like sensations and emotions are commonly held to be: there may be no appropriate way of describing their phenomenal character apart from describing the properties and objects they represent. (shrink)

One popular approach to theorizing about phenomenal consciousness has been to connect it to representations of a certain kind. Representational theories of consciousness can be further sub-divided into first-order and higher-order theories. Higher-order theories are often interpreted as invoking a special relation between the first-order state and the higher-order state. However there is another way to interpret higher-order theories that rejects this relational requirement. On this alternative view phenomenal consciousness consists in having suitable higher-order representations. I call this ‘HOROR’ (‘Higher-Order (...) Representation Of a Representation’) theory to distinguish it from relational versions of higher- order theory. In this paper I make the case that HOROR theory is a plausible account of the real nature of phenomenal consciousness whatever one’s views are about whether it is physical/reducible or not. I first clarify HOROR theory and compare it to the more traditional same-order and higher-order thought theories. Afterwards I move to presenting some considerations in favor of HOROR theory.

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.

Contemporary phenomenal externalists are motivated to a large extent by the transparency of experience and by the related doctrine of representationalism. On their own, however, transparency and representationalism do not suffice to establish externalism. Hence we should hesitate to dismiss phenomenal internalism, a view shared by many generations of competent philosophers. Rather, we should keep both our options open, internalism and externalism. It is hard, however, to see how to keep open the internalist option, for although transparency and representationalism have (...) not yet definitively established externalism, they have indeed made it quite intuitive. Internalism, by comparison, comes across at first sight as antiquated and ridden with difficulties. This is why I propose the Stained Glass model of consciousness. I do so with the following two aims: first, to make internalism intuitive in the age of transparency, and second, to show how to resist the many recent anti-internalist arguments. In particular, I argue that phenomenal internalism need not be epistemically worrisome, that it is compatible at once with transparency, representationalism, and content externalism, and that although it requires an error theory, this error theory is a harmless one.

Abstract In recent debates, both physicalist and anti-physicalist philosophers of mind have come to agree that understanding the nature of phenomenal concepts is key to understanding the nature of phenomenal consciousness itself. Recently, however, Derek Ball (2009) and Michael Tye (2009) have argued that there are no such concepts. Their case is especially troubling because they make use of a type of argument that proponents of phenomenal concepts have typically found persuasive in other contexts; namely, arguments much like those that (...) Tyler Burge used to motivate a certain form of externalism about mental content. The goal of this paper is to defend phenomenal concepts against this line of attack. Burge-style arguments, I contend, cannot be successfully used to make the case that there are no phenomenal concepts. As such, phenomenal concepts must remain central to understanding the nature of phenomenal consciousness. (shrink)

According to social externalism, it is possible to possess a concept not solely in virtue of one’s intrinsic properties but also in virtue of relations to one’s linguistic community. Derek Ball (2009) argues, in effect, that (i) social externalism extends to our concepts of colour experience and (ii) this fact undermines both the knowledge argument against physicalism and the most popular physicalist response to it, known as the phenomenal concept strategy. I argue that Ball is mistaken about (ii) even granting (...) (i). The knowledge argument and the phenomenal concept strategy might have to be modified to make them consistent with social externalism, but not in fundamental or detrimental ways. (shrink)

In the philosophy of perception, typically, everything is illuminated. Discussions of perceptual experience primarily focus on subjects situated in illuminated environs. Rarely do we see treatment of putative perceptual experience involving darkness. In this paper, I will carefully canvas and characterize the nature of experiences of darkness, marking a substantive distinction between two such kinds of experiences. Crucially, I give an account of the distinctive phenomenology of experiences of darkness, and show that neither of the two broad kinds of experiences (...) of darkness requires, as Roy Sorensen has recently suggested, the reification of unfamiliar entities to serve as objects of perceptual awareness. I will also offer potential candidates for the proper representational contents of experiences of darkness. This exploration not only reveals that such experiences pose no threat to a view like representationalism, but also demonstrates how experiences of darkness can be given their rightful place in a naturalistic theory of perceptual awareness. Atlast, darkness will be brought out from the shadows.

It's a common idea in philosophy that we possess a peculiar kind of "phenomenal concept" by which we can think about our conscious states in "inner" and "direct" ways, as for example, when I attend to the way a current pain feels and think about this feeling as such. Such phenomenal ways of thinking figure in a variety of theoretical contexts. The bulk of this article discusses their use in a certain strategy – the phenomenal concept strategy – for defending (...) the physicalist view that conscious states are reducible to brain states. It also considers, more briefly, how phenomenal concepts have been used to defend dualism about consciousness, and how they have been used to explain our special access to our consciousness. It concludes with a discussion about whether, and in what more precise sense of the term, we at all possess "phenomenal concepts" of our conscious states. (shrink)

Abstract: In philosophy, perceptual constancy refers to the puzzling phenomenon of the perception of properties of objects despite our changing experience of those properties. Husserl developed a sophisticated description of perceptual constancy. In this paper I sketch Husserl's approach, which focuses on the suggestion that perception is partly constituted by the continuous interplay of intention and fulfilment. Unlike many contemporary theories, this framework gives us a way to understand the relationship between different appearances of the same object. I will show (...) how Husserl's work connects with contemporary theories which emphasize perceptual constancy from particular perspectives. These theories include appeals to perspectival properties and Cohen's counterfactual theory. Also, I show how Husserl's account shares important themes with Kelly's recent interpretation of Merleau-Ponty on perceptual constancy. (shrink)

It has long been widely agreed that some concepts can be possessed only by those who have undergone a certain type of phenomenal experience. Orthodoxy among contemporary philosophers of mind has it that these phenomenal concepts provide the key to understanding many disputes between physicalists and their opponents, and in particular offer an explanation of Mary’s predicament in the situation exploited by Frank Jackson's knowledge argument. I reject the orthodox view; I deny that there are phenomenal concepts. My arguments exploit (...) the sort of considerations that are typically used to motivate externalism about mental content. Although physicalists often appeal to phenomenal concepts to defend their view against the knowledge argument, I argue that this is a mistake. The knowledge argument depends on phenomenal concepts; if there are no phenomenal concepts, then the knowledge argument fails. (shrink)

Frank Jackson endorses epiphenomenalism because he thinks that his knowledge argument undermines physicalism. One of the most interesting criticisms of Jackson's position is what I call the 'inconsistency objection'. The inconsistency objection says that Jackson's position is untenable because epiphenomenalism undermines the knowledge argument. The inconsistency objection has been defended by various philosophers independently, including Michael Watkins, Fredrik Stjernberg, and Neil Campbell. Surprisingly enough, while Jackson himself admits explicitly that the inconsistency objection is 'the most powerful reply to the knowledge (...) argument' he knows of, it has never been discussed critically. The aim of this paper is to evaluate the objection and to identify and consider its implications. The objection is alleged to be based on a causal theory of knowledte. I argue that the objection fails by showing that any causal theory of knowledge is such that it is either false or does not support the inconsistency objection. In order to defend my argument, I offer a hypothesis concerning phenomenal knowledge. (shrink)

One popular materialist response to the explanatory gap identifies phenomenal concepts with type-demonstrative concepts. This kind of response, however, faces a serious challenge: that our phenomenal concepts seem to provide a richer characterization of their referents than just the demonstrative characterization of 'that quality'. In this paper, I develop a materialist account that beefs up the contents of phenomenal concepts while retaining the idea that these contents contain demonstrative elements. I illustrate this account by focusing on our phenomenal concepts of (...) phenomenal colour. The phenomenal colours stand in a similarity space relative to one another in virtue of being complex qualities—qualities that contain saturation, lightness, and various aspects of hue as component elements. Our phenomenal concepts, in turn, provide a demonstrative characterization of each of these component elements as well as a description of how much of that element is present in a given phenomenal colour. The result is an account where phenomenal concepts contain demonstrative elements and yet provide a significantly richer characterization of the intrinsic nature of their referents than just 'that quality'.

Kripke's argument against the identity theory in the philosophy of mind runs as follows. Suppose some psychophysical identity statement S is true. Then S would seem to be contingent at least in the sense that S seems possibly false. And given that seeming contingency entails genuine contingency when it comes to such statements S is contingent. But S is necessary if true. So S is false. This entry considers responses to each of the three premises. It turns out that each (...) response does not fully withstand scrutiny, and so Kripke's conclusion is hard to resist. Section 1 lays out Kripke's argument, and Sections 2 to 4 then discuss responses to each of the three premises respectively. (shrink)

Representationalists argue that phenomenal states are intentional states of a special kind. This paper offers an account of the kind of intentional state phenomenal states are: I argue that they are underived intentional states. This account of phenomenal states is equivalent to two theses: first, all possible phenomenal states are underived intentional states; second, all possible underived intentional states are phenomenal states. I clarify these claims and argue for each of them. I also address objections which touch on a range (...) of topics, including meaning holism and concept empiricism. I conclude with a brief discussion of the consequences of the proposed view for the project of naturalizing consciousness. (shrink)

This essay is a sustained attempt to bring new light to some of the perennial problems in philosophy of mind surrounding phenomenal consciousness and introspection through developing an account of sensory and phenomenal concepts. Building on the information-theoretic framework of Dretske (1981), we present an informational psychosemantics as it applies to what we call sensory concepts, concepts that apply, roughly, to so-called secondary qualities of objects. We show that these concepts have a special informational character and semantic structure that closely (...) tie them to the brain states realizing conscious qualitative experiences. We then develop an account of introspection which exploits this special nature of sensory concepts. The result is a new class of concepts, which, following recent terminology, we call phenomenal concepts: these concepts refer to phenomenal experience itself and are the vehicles used in introspection. On our account, the connection between sensory and phenomenal concepts is very tight: it consists in different semantic uses of the same cognitive structures underlying the sensory concepts, such as the concept of red. Contrary to widespread opinion, we show that information theory contains all the resources to satisfy internalist intuitions about phenomenal consciousness, while not offending externalist ones. A consequence of this account is that it explains and predicts the so-called conceivability arguments against physicalism on the basis of the special nature of sensory and phenomenal concepts. Thus we not only show why physicalism is not threatened by such arguments, but also demonstrate its strength in virtue of its ability to predict and explain away such arguments in a principled way. However, we take the main contribution of this work to be what it provides in addition to a response to those conceivability arguments, namely, a substantive account of the interface between sensory and conceptual systems and the mechanisms of introspection as based on the special nature of the information flow between them.

This paper defends a non-reductive realist view of the sensible qualities—roughly, the view that the sensible qualities are really instantiated by the external objects of perception, and not reducible to response-independent physical properties or response-dependent relational properties. I begin by clarifying and motivating the non-reductive realist view. I then consider some familiar difficulties for the view. Addressing these difficulties leads to the development and defence of a general theory, inspired by Russellian Monist theories of consciousness, of how the sensible qualities (...) relate to physical reality. I conclude by showing how this theory, which I call ‘Secondary Quality Russellian Monism’, resolves the most significant difficulties for the non-reductive realist view of the sensible qualities.

Currently, one of the most influential theories of consciousness is Rosenthal's version of higher-order-thought (HOT). We argue that the HOT theory allows for two distinct interpretations: a one-component and a two-component view. We further argue that the two-component view is more consistent with his effort to promote HOT as an explanatory theory suitable for application to the empirical sciences. Unfortunately, the two-component view seems incapable of handling a group of counterexamples that we refer to as cases of radical confabulation. We (...) begin by introducing the HOT theory and by indicating why we believe it is open to distinct interpretations. We then proceed to show that it is incapable of handling cases of radical confabulation. Finally, in the course of considering various possible responses to our position, we show that adoption of a disjunctive strategy, one that would countenance both one-component and two-component versions, would fail to provide any empirical or explanatory advantage.

P.F. Strawson argued that ‘mature sensible experience (in general) presents itself as … an immediate consciousness of the existence of things outside us’ (1979: 97). He began his defence of this very natural idea by asking how someone might typically give a description of their current visual experience, and offered this example of such a description: ‘I see the red light of the setting sun filtering through the black and thickly clustered branches of the elms; I see the dappled deer (...) grazing in groups on the vivid green grass…’ (1979: 97). In other words, in describing experience, we tend to describe the objects of experience – the things which we experience – and the ways they are when we are experiencing them. Some go further. According to Heidegger. (shrink)

In this paper, I consider a view that explains colour experience by the independent representation of surface and illumination. This view implies that surface colour is a phenomenal perceptual content. I argue from facts of colour phenomenology to the conclusion that surface colour is not a phenomenal perceptual content. I then argue from results of surface-matching experiments to the conclusion that surface colour is neither a perceptual content of any kind nor any sort of computational output of the perceptual system. (...) These conclusions contradict widely accepted views in both the philosophy of perception and colour science. I finish by considering and rejecting a competing account of the surface-matching results, according to which surface colour is represented indeterminately in perception. (shrink)

Colour relationalism holds that the colours are constituted by relations to subjects. Anti-relationalists have claimed that this view stands in stark contrast to our phenomenally-informed, pre-theoretic intuitions. Is this claim right? Cohen and Nichols’ recent empirical study suggests not, as about half of their participants seemed to be relationalists about colour. Despite Cohen and Nichols’ study, we think that the anti-relationalist’s claim is correct. We explain why there are good reasons to suspect that Cohen and Nichols’ experimental design skewed their (...) results in favour of relationalism. We then run an improved study and find that most of our participants seem to be anti-relationalists. We find some other interesting things too. Our results suggest that the majority of ordinary people find it no less intuitive that colours are objective than that shapes are objective. We also find some evidence that when those with little philosophical training are asked about the colours of objects, their intuitions about colour and shape cases are similar, but when asked about people’s colour ascriptions, their intuitions about colour and shape cases differ.

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

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)

Cohen, Hardin, and McLaughlin (2006) complain that my solution to the puzzle of true blue (Tye 2006) depends upon my assuming that 'all variation in colour experience among standard perceivers in standard circumstances is at the level of fine-grained hues (4)'. That assumption, they say, is false: 'there is in fact variation in colour experience among.

Representationalists who hold that phenomenal character can be explained in terms of representational content currently cannot explain counter-examples that involve indeterminate perceptual content, such as in the case of objects seen blurrily by someone with poor eyesight, or objects seen vaguely in misty conditions. But this problem can be resolved via provision of a more sophisticated double content (DC) view, according to which the representational content of perception is structured in two nested levels. I start by outlining the DC view (...) via consideration of four closely related cases of perceptual imprecision. Then, after a demonstration that the DC view can also explain imprecise photographic content, inadequacies in the more standard single content (SC) view are demonstrated. The results are then generalized so as to apply to the content of any kinds of non-conventional representation. The paper continues with evidence that a DC account provides a moderate rather than extreme realist account of perception, and it concludes with an initial analysis of the failure of nomic covariance accounts of information in indeterminacy cases.

Eric Schwitzgebel (2011) argues that phenomenal judgments are in general less reliable than perceptual judgments. This paper distinguishes two versions of this unreliability thesis. The process unreliability thesis says that unreliability in phenomenal judgments is due to faulty domain-specific mechanisms involved in producing these judgments, whereas the statistical unreliability thesis says that it is simply a matter of higher numbers of errors. Against the process unreliability thesis, I argue that the main errors and limitations in making phenomenal judgments can be (...) accounted for by domain-general factors: attention, working memory limits and conceptualization. As these factors are shared with the production of perceptual judgments, errors in phenomenal judgments are not due to faulty domain-specific processes. Furthermore, this account defends phenomenal judgments against general scepticism by providing criteria for distinguishing between reliable and unreliable phenomenal judgments. (shrink)

We perceive a world of mind-independent macroscopic material objects such as stones, tables, trees, and animals. Our experience is the joint upshot of the way these things are and our route through them, along with the various relevant circumstances of perception; and it depends on the normal operation of our perceptual systems. How should we characterise our perceptual experience so as to respect its basis and explain its role in grounding empirical thought and knowledge? I offered an answer to this (...) question in Perception and its objects. Here I aim to clarify some of my central arguments and to develop and defend the position further in the light of subsequent critical discussion. (shrink)

Existentialist accounts maintain that visual phenomenal content takes the logical form of an existentially quantified sentence. These accounts do not make phenomenal content specific enough. Singularist accounts posit a singular content in which the seen object is a constituent. These accounts make phenomenal content too specific. My account gets the specificity of visual phenomenal content just right. My account begins with John Searle's suggestion that visual experience represents an object as seen, moves this relation outside the scope of the existential (...) quantifier and then replaces it with the relation of objects being ‘present as accessible’, as described by Alva Noë.

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

Is phenomenal consciousness a problem for the brain sciences? An increasing number of researchers hold not only that it is but that its very existence is a deep mystery. That this problematic phenomenon exists is generally taken for granted: It is asserted that phenomenal consciousness is just phenomenologically obvious. In contrast, I hold that there is no such phenomenon and, thus, that it does not pose a problem for the brain sciences. For this denial to be plausible, however, I need (...) to show that phenomenal consciousness is not phenomenologically obvious.

I defend externalism about color experiences and color thoughts, which I argue color objectivism requires.

From the work of Ned Block, David Velleman, Paul Boghossian, Michael Tye, and Fiona Macpherson, I extract problems facing those who answer “Yes” and problems facing those who answer “No.” I show how these problems can be overcome, leaving (...) externalism available to the color objectivist.

This paper expands on the discussion in the first section of 'Beyond phenomenal naivete'. Let Phenomenal Naivete be understood as the doctrine that some phenomenal characters of veridical experiences are factive properties concerning the external world. Here I present in detail a phenomenological case for Phenomenal Naivete and an argument from hallucination against it. I believe that these arguments show the concept of phenomenal character to be defective, overdetermined by its metaphysical and epistemological commitments together with the world. This does (...) not establish a gappish eliminativism, but a gluttish pluralism, on which there are many imperfect deservers of the name 'phenomenal character'. Different projects in the philosophy of mind -- phenomenology, philosophy of conscious, metaphysics and epistemology of perception -- are concerned with different deservers of the name. (shrink)

David Enoch, in his paper “Why Idealize?”, argues that theories of normative reasons that hold that normative facts are subject or response-dependent and include an idealization condition might have a problem in justifying the need for idealization. I argue that at least some response-dependence conceptions of normative reasons can justify idealization. I explore two ways of responding to Enoch’s challenge. One way involves a revisionary stance on the ontological commitments of the normative discourse about reasons. To establish this point, I (...) argue by analogy with the case of color perception. To make the analogy, it suffices to show that even if colors are response-dependent properties, it does not follow that some kind of idealization cannot be introduced to specify the truth conditions of color ascriptions. The second route involves the denial of Enoch’s contention that our normative discourse is implicitly committed to a realist ontology. I adduce reasons for thinking that our normative discourse only presupposes a possibility of misrepresentation. However, this feature of the normative discourse does not favor robustly objectivist as opposed to response-dependence accounts of normative reasons. Thus, I argue that proponents of response-dependence accounts can use this feature to answer the question of why to idealize. (shrink)
