At the very heart of the mind-body problem is the question of the nature of consciousness. It is consciousness, and in particular _phenomenal_ consciousness, that makes the mind-body relation so deeply perplexing. Many philosophers hold that no defi nition of phenomenal consciousness is possible: any such putative defi nition would automatically use the concept of phenomenal consciousness and thus render the defi nition circular. The usual view is that the concept of phenomenal consciousness is one that must be explained by (...) means of specifi c examples and associated comments. (shrink)

Dennett provides a much discussed argument for the nonexistence of qualia, as conceived by philosophers like Block, Chalmers, Loar and Searle. My goal in this paper is to vindicate Dennett's argument, construed in a certain way. The argument supports the claim that qualia are constitutively representational. Against Block and Chalmers, the argument rejects the detachment of phenomenal from information-processing consciousness; and against Loar and Searle, it defends the claim that qualia are constitutively representational in an externalist understanding of this. The (...) core of the argument is contained in section 3. In the first part, I contrast a minimal conception of qualia, relative to which their existence is not under dispute, with the sort of view to which I will object. In the second part I set the stage by presenting the facts about qualia on which a Dennett-like argument can be based. (shrink)

Relying on a range of now‐familiar thought‐experiments, it has seemed to many philosophers that phenomenal consciousness is beyond the scope of reductive explanation. (Phenomenal consciousness is a form of state‐consciousness, which contrasts with creature‐consciousness, or perceptual ‐consciousness. The different forms of state‐consciousness include various kinds of access‐consciousness, both first‐order and higher‐order–see Rosenthal, 1986; Block, 1995; Lycan, 1996; Carruthers, 2000. Phenomenal consciousness is the property that mental states have when it is like something to possess them, or when they have subjectively‐accessible (...) feels; or as some would say, when they have qualia (see fn. l below).) Others have thought that we can undermine the credibility of those thought‐experiments by allowing that we possess purely recognitional concepts for the properties of our conscious mental states. This paper is concerned to explain, and then to meet, the challenge of showing how purely recognitional concepts are possible if there are no such things as qualia–in the strong sense of intrinsic (non relational, non‐intentional) properties of experience. It argues that an appeal to higher‐order experiences is necessary to meet this challenge, and then deploys a novel form of higher‐order thought theory to explain how such experiences are generated.

This paper develops an adverbial theory of consciousness. Adverbialism is described and endorsed and defended from its near rival, an identity thesis in which conscious mental states are those that the mental subject self-knows immediately that he or she is "in". The paper develops an account of globally supported self-ascription to embed this neo-Brentanian view of experiencing consciously within a more general account of the relation between consciousness and self-knowledge. Following O'Shaughnessy, person level consciousness is explained as a feature of (...) the bundle of mental capacities characteristic of persons: person level consciousness involves a capacity holism. Drawing on Kant, it is argued that if a person is in a mental state intentionally directed to an object then such a subject can "self token" such knowledge. The content of that self-knoweldge supervenes on the possession of a global set of capacities, and this capacity for self-ascription depends on the fact that our experience has a perspectival character with, as it were, nothing at the vanishing point of this perspective. The fact that one can attach the cogito to any one of one's representation shows a truth about the unity of the conscious life of a person that cannot be stated and this capacity is distinguished from self-conscious thinking about oneself. This approach is contrasted to Shoemaker's functionalist treatment of the self-tokening of conscious states and of "self-blindness". It is argued that to be fully consistent, Shoemaker has to abandon the claim that introspectionism is guilty of a self-scanning model or rational control as he seems committed to that model too.

In this lucid, deep, and entertaining book, John Perry supposes that type-identity physicalism is antecedently plausible, and that rejecting this thesis requires good reason. He aims to show that experience gap arguments, as given by Jackson, Kripke, and Chalmers, fail to provide such reason, and moreover that each failure stems from an overly restrictive conception of the content of thought.

This paper was chosen by The Philosopher’s Annual as one of the ten best articles appearing in print in 2000. Reprinted in Volume XXIII of The Philosopher’s Annual. In his very influential book David Chalmers argues that if physicalism is true then every positive truth is a priori entailed by the full physical description – this is called “the a priori entailment thesis – but ascriptions of phenomenal consciousness are not so entailed and he concludes that Physicalism is false. As (...) he puts it, “zombies” are metaphysically possible. I attempt to show that this argument is refuted by considering an analogous argument in the mouth of a zombie. The conclusion of this argument is false so one of the premises is false. I argue at length that this shows that the original conceivability argument also has a false premise and so is invalid.

Investigation and analysis of the history of the concepts employed in contemporary philosophy of mind could significantly change the contemporary debate about the explainability of consciousness. Philosophical investigation of the history of the concept of qualia and the concept of scientific explanation most often presupposed in contemporary discussions of consciousness reveals the origin of both concepts in some of the most interesting philosophical debates of the twentieth century. In particular, a historical investigation of the inheritance of concepts of the elements (...) of experience and the nature of scientific explanation from C. I. Lewis and Rudolf Carnap to contemporary theorists like David Chalmers shows the profound continuity of these concepts throughout the analytic tradition, despite important changes in the dimensions of philosophical relevance and significance that have characterized the emerging debate. I argue that, despite the significant methodological shift from the foundationalist epistemology of the 1920s to today's functionalist explanations of the mind, the problem of explaining consciousness has remained the problem of analysing or describing the logical and relational structure of immediate, given experience. Appreciation of this historical continuity of form recommends a more explicit discussion of the philosophical reasons for the underlying distinction between structure and content, reasons that trace to Lewis and Carnap's influential but seldom-discussed understanding of the relationship between subjectivity, conceived as the realm of private, ineffable contents, and objectivity, understood as public, linguistic expressibility. With this historical background in mind, the contemporary debate about the explanation of consciousness can be re-interpreted as a debate about the relationship between ineffable experience and structurally conceived meaning.

A general trend in recent philosophical and empirical work aims to undermine various traditional claims regarding the distinctive nature of self-knowledge. So far, however, this work has not seriously threatened the Cartesian claim that (at least some) self-knowledge is immune to the sort of sceptical problem that seems to afflict our knowledge of the external world. In this paper I carry this trend further by arguing that the Cartesian claim is false. This is done by showing that a familiar sceptical (...) argument that targets my knowledge of the external world can be adapted to target my belief that I exist, along with any of my self-knowledge that I know entails my own existence. Thus, my self-knowledge and my knowledge of the external world are subject to the same sort of sceptical problem. (shrink)

According to a posteriori physicalism, phenomenal properties are physical properties, despite the unbridgeable cognitive gap that holds between phenomenal concepts and physical concepts. Current debates about a posteriori physicalism turn on what I call “the perspicuity principle”: it is impossible for a suitably astute cognizer to possess concepts of a certain sort—viz., narrow concepts—without being able to tell whether the referents of those concepts are the same or different. The perspicuity principle tends to strike a posteriori physicalists as implausibly rationalistic; (...) further, a posteriori physicalists maintain that even if the principle is applicable to many narrow concepts, phenomenal concepts have unique features that render them inferentially isolated from other narrow concepts ). I argue, on the contrary, that the case for the perspicuity principle is quite strong. Moreover, not only have versions of the PCS repeatedly failed, likely, all versions will, given the strange combination of lucidity and opacity that the PCS has to juggle. I conclude that a posteriori physicalists currently lack a principled objection to classic anti-physicalist arguments. (shrink)

Chalmers’ meta-problem of consciousness is the problem of explaining “problem reports”; i.e. reports to the effect that phenomenal consciousness has the various features that give rise to the hard problem. Chalmers suggests that solving the meta-problem will likely “shed significant light on the hard problem.” Against this, I argue that work on the meta-problem will likely fail to make the hard problem any easier. For each of the main stances on the hard problem can provide an account of problem reports, (...) and we have no way of deciding which of these accounts gives the correct explanation of an individual’s problem reports without presupposing a stance on the hard problem. We thus cannot determine which of the available solutions to the meta-problem is correct without having already solved the hard problem. (shrink)

How do we know about other minds on the basis of perception? The two most common answers to this question are that we literally perceive others’ mental states, or that we infer their mental states on the basis of perceiving something else. In this paper, I argue for a different answer. On my view, we don’t perceive mental states, and yet perceptual experiences often immediately justify mental state attributions. In a slogan: other minds are neither seen nor inferred. I argue (...) that this view offers the best explanation of our deeply equivocal intuitions about perception-based mental state attributions, and also holds substantial interest for the epistemology of perception more generally.

Knowledge of what it’s like to have perceptual experiences, e.g. of what it’s like to see red or taste Turkish coffee, is phenomenal knowledge; and it is knowledge the substantial or significant nature of which is widely assumed to pose a challenge for physicalism. Call this the New Challenge to physicalism. The goal of this paper is to take a closer look at the New Challenge. I show, first, that it is surprisingly difficult to spell out clearly and neutrally what (...) the New Challenge is in fact urging the physicalist to explain. What initially look like plausible or promising ways of making sense of it turn out to be either question begging or insufficient to generate a challenge to physicalism at all. I go on to suggest that what the New Challenge may be asking the physicalist to explain may be the fact that we come to token certain higher-order judgments about the significance of phenomenal knowledge. I end with a discussion of the implications of this interpretation of the New Challenge—which turns out to be as much a challenge for the anti-physicalist as it is for the physicalist. (shrink)

This paper discusses Husserl’s theory of intentionality and compares it to contemporary debates about intentionalism. I first show to what extent such a comparison could be meaningful. I then outline the structure of intentionality as found in Ideas I. My main claims are that – in contrast with intentionalism – intentionality for Husserl covers just a region of conscious contents; that it is essentially a relation between act-processes and presented content; and that the side of act-processes contains non-representational contents. In (...) the third part, I show that Husserl also offers resources against intentionalism’s exclusive concern with propositional content. (shrink)

This paper introduces a new approach to the study of Paleolithic minds. It is developed on the basis of the phenomenological concept of intentionality: the mind's central characteristic of being about or directed at something. In phenomenology, the world is considered not qua fact, but qua appearance, as a correlate of the mind's intentional activity. Both world-appearance and the mind's directedness are further considered from a first-person viewpoint, and in a scaffolding fashion, with more complex acts disclosing new types of (...) objects or aspects of them. This paper develops a framework for applying intentional analysis to minds of the past. This way, the subjective “world-having” of past subjects can be systematically reconstructed in a manner consistent with the empirical data available. This discloses a new field of inquiry that thus far has not been clearly grasped, even though the questions belonging to it are everywhere recognized as being of the greatest importance to the discipline. The intentional analysis of the scaffolding of acts and what they disclose can help to clarify essential concepts in cognitive archaeological debates, and to better understand the evolution of the hominin mind.

1) There is widespread agreement that consciousness must be a physical phenomenon, even if it is one that we do not yet understand and perhaps may never do so fully. There is also widespread agreement that the way to defend physicalism about consciousness against a variety of well known objections is by appeal to phenomenal concepts (Loar 1990, Lycan 1996, Papineau 1993, Sturgeon 1994, Tye 1995, 2000, Perry 2001) . There is, alas, no agreement on the nature of phenomenal concepts.

The argument at Phaedo 74 B 4‐C 6 that the equal itself is ‘something different from’ sets of physical equals depends on Leibniz's Law: there is a property that perceptible equals have that the equal itself does not have. What I call the ‘epistemic interpretation’ holds that the property is an epistemic one: having appeared unequal. The ‘ontological interpretation’ holds that the property is not epistemic, but simply the property of being unequal. The most natural reading of the text favours (...) the epistemic interpretation; scholarly support for the ontological interpretation is based on the widely held view that on the epistemic interpretation the argument is manifestly invalid. But this view implicitly relies on an impoverished sense of ‘appearing’ as equivalent to ‘being thought’. Drawing on an analogy with colour perception, I elaborate an experiential sense of ‘appearing’ which makes Plato's argument on the epistemic interpretation philosophically defensible. (shrink)

Dispositional realism, as we shall use the term, is a non-reductive, anti-Humean approach to dispositions which says that natural properties confer certain dispositions as a matter of metaphysical necessity. A strong form of dispositional realism is known as pan-dispositionalism, which is typically interpreted as the view that all natural properties are identical with, or essentially dependent on, dispositions. One of the most serious problems facing pan-dispositionalism is the conceivability objection, and the solution commonly offered by essentialists employs the so-called redescription (...) strategy. In this paper I argue that this orthodox strategy fails in certain cases. This argument, in turn, shows that essentialist forms of dispositional realism are implausible. The discussion points us towards an improved version of dispositional realism. According to this new version, natural properties are not essentially dispositional but necessarily ground dispositions. (shrink)

Notoriously, the dispositional view of natural properties is thought to face a number of regress problems, one of which points to an epistemological worry. In this paper, I argue that the rival categorical view is also susceptible to the same kind of regress problem. This problem can be overcome, most plausibly, with the development of a structuralist epistemology. After identifying problems faced by alternative solutions, I sketch the main features of this structuralist epistemological approach, referring to graph-theoretic modelling in the (...) process. Given that both the categoricalists and dispositionalists are under pressure to adopt this same epistemological approach in light of the regress problem, this suggests that the categoricalist versus dispositionalist debate is best fought on metaphysical rather than epistemological grounds.

Discussion of the challenge that acquaintance with the nature of experience poses to physicalism.

Most philosophers who have endorsed the idea that there is such a thing as phenomenal content—content that supervenes on phenomenal character—have also endorsed what I call Standard Russellianism. According to Standard Russellianism, phenomenal content is Russellian in nature, and the properties represented by perceptual experiences are mind-independent physical properties. In agreement with Sydney Shoemaker [Shoemaker, S. (1994). Philosophy and Phenomenological Research, 54 249–314], I argue that Standard Russellianism is incompatible with the possibility of spectrum inversion without illusion. One defense of (...) (...) Standard Russellianism is to hold that spectrum inversion without illusion is conceivable but not in fact possible. I argue that this response fails. As a consequence, either phenomenal content is not Russellian, or experiences do not represent mind-independent physical properties. (shrink)

Defenders of the phenomenal concept strategy have to explain how both physical and phenomenal concepts provide a substantive grasp on the nature of their referents, whilst referring to the very same experience. This is the ‘new challenge’ to physicalism. In this paper, I argue that if the physicalist adopts the powerful qualities ontology of properties then a new and powerful version of the phenomenal concept strategy can be developed, which answers the new challenge.

Though physicalism remains the most popular position in the metaphysics of mind today, there is still considerable debate over how to retain a plausible account of mental concepts consistently with a physicalistic world view. Philip Goff (Australasian Journal of Philosophy 89(2), 191–209, 2011) has recently argued that physicalism cannot give a plausible account of our phenomenal concepts, and that as such, physicalism should be rejected. In this paper I hope to do three things, firstly I shall use some considerations from (...) ontology to rebut Goff’s argument and consider some objections and replies. Secondly, I shall outline a version of a posteriori physicalism about phenomenal consciousness which draws on this particular ontology. Thirdly, I shall give support to this version of physicalism by arguing that it marries well with prominent theories in cognitive science, and has important advantages over other versions of a posteriori physicalism.

The ontology of ‘powerful qualities’ is gaining an increasing amount of attention in the literature on properties. This is the view that the so-called categorical or qualitative properties are identical with ‘dispositional’ properties. The position is associated with C.B. Martin, John Heil, Galen Strawson and Jonathan Jacobs. Robert Schroer ( 2012 ) has recently mounted a number of criticisms against the powerful qualities view as conceived by these main adherents, and has also advanced his own (radically different) version of the (...) view. In this paper I have three main aims: firstly, I shall defend the ontology from his critique, arguing that his criticisms do not damage the position. Secondly, I shall argue that Schroer’s own version of the view is untenable. Thirdly, the paper shall serve to clear up some conceptual confusions that often bedevil the powerful qualities view.

Imagism about Phenomenal Thought is (roughly) the view that there is some concept *Q* (for some sensory quality Q) that we can employ only while we experience the quality Q. I believe this view is theoretically significant, is or can be made intuitively appealing, and is explicitly or implicitly accepted by many contemporary philosophers However, there is no good reason to accept it. Or so I argue.

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)

A number of philosophers have recently argued that consciousness properties are identical with some set of physical or functional properties and that we can explain away the frequently felt puzzlement about this claim as a delusion or confusion generated by our different ways of apprehending or thinking about consciousness. This paper examines David Papineau’s influential version of this view. According to Papineau, the difference between our “phenomenal” and “material” concepts of consciousness produces an instinctive but erroneous intuition that these concepts (...) can’t co-refer. I claim that this account fails. To begin with, it is arguable that we are mystified about physicalism even when the account predicts that we shouldn’t be. Further, and worse, the account predicts that an “intuition of distinctness” will arise in cases where it clearly does not. In conclusion, I make some remarks on the prospects for, constraints on, and alternatives to, a successful defence of the claim. (shrink)

HOST is the theory that to be conscious of a mental state is totarget it with a higher-order state (a `HOS'), either an innerperception or a higher-order thought. Some champions of HOSTmaintain that the phenomenological character of a sensory stateis induced in it by representing it with a HOS. I argue that thisthesis is vulnerable to overwhelming objections that flow largelyfrom HOST itself. In the process I answer two questions: `What isa plausible sufficient condition for a quale's belonging to aparticular (...) mental state?' and `What is the propositional contentof HOSs that target sensory states?'.

The debate over physicalism in philosophy of mind can be seen as concerning an inconsistent tetrad of theses: (1) if physicalism is true, a priori physicalism is true; (2) a priori physicalism is false; (3) if physicalism is false, epiphenomenalism is true; (4) epiphenomenalism is false. This paper argues that one may resolve the debate by distinguishing two conceptions of the physical: on the theory‐based conception, it is plausible that (2) is true and (3) is false; on the object‐based conception, (...) it is plausible that (3) is true and (2) is false. the paper also defends and explores the version of physicalism that results from this strategy.

A phenomenal concept is the concept of a particular type of sensory or perceptual experience, where the notion of experience is understood phenomenologically. A recent and increasingly influential idea in philosophy of mind suggests that reflection on these concepts will play a major role in the debate about conscious experience, and in particular in the defense of physicalism, the thesis that psychological truths supervene on physical truths. According to this idea—I call it the phenomenal concept strategy —phenomenal concepts are importantly (...) different from other concepts, and arguments against physicalism fatally neglect to take this difference into account. This paper divides the phenomenal concept strategy into a number of different versions, and argues that no version of the strategy is successful. The paper ends by contrasting the phenomenal concept strategy with a rival strategy—I call it the missing concept strategy . I suggest that the missing concept strategy presents a more plausible response to the issues about physicalism and experience. (shrink)

This chapter reviews four elements of David Lewis's account of materialism and experience. These elements include: materialism for which Lewis gave a distinctive and well‐known characterization; an account of what experience is; an account of the source of the tension between experience and materialism; and a strategy for resolving the tension. Lewis did not just give a distinctive and well‐known characterization of materialism, he gave two: one in terms of fundamental properties, and one in terms of supervenience. The chapter considers (...) two recent objections to that account. The first argues that knowledge‐how is a certain kind of knowledge‐that and in consequence Lewis's well‐known “ability hypothesis” fails. The second argues that if Lewis's contextualist approach to epistemology is correct, his rejection of the identification thesis is impossible. The author suggests that Lewis has the resources to answer both objections, but he ends by stating the real problems for Lewis's lie. (shrink)

Much recent work on empathy assumes that one cannot give non-question-begging reasons for empathizing with others. In this article I argue that there are epistemic reasons for cultivating empathy. After sketching a brief general account of empathy, I proceed to argue that empathic information is user-friendly, fostering the achievement of widely held cognitive goals. It can also contribute to social knowledge and the satisfaction of democratic ideals. The upshot of my analysis is that there are strong, but defeasible, epistemic reasons (...) for empathizing with others. (shrink)

In this paper I critically examine uses of introspection in present-day philosophy of perception. First, I introduce a distinction between two different meanings of the term ‘introspection’: introspective access and introspective method. I show that they are both at work in the philosophy of perception but not adequately distinguished. I then lay out some concerns about the use of introspection to collect data about consciousness that were raised in over a hundred years ago, by some early experimentalist psychologists, part of (...) so-called ‘Introspectionist Psychology’. As I argue, these concerns apply to current philosophical uses of introspection but they are not acknowledged, much less addressed. I explain this by applying the distinction between introspective access and introspective method. As a result, extant arguments relying on introspection-based phenomenal descriptions are methodologically problematic. These problems do not call into question the use of introspection in theorising altogether. But we need to take more care in how we use it. (shrink)

I present a novel objection to fine-tuning arguments for God's existence. On any values of the physical constants, the psychophysical laws could be set to permit intelligent and happy beings, so the specific values of the physical constants in our world provide little evidence for God's existence. For example, even if the physical constants didn't allow carbon or any atoms larger than hydrogen, the psychophysical laws could be set so that charge is sufficient to realize romantic desire. Then every hydrogen (...) atom would be a proton and electron in love. (shrink)

Plain phenomenology explains theoretically salient mental or psychological distinctions with an appeal to their first-person applications. But it does not assume that warrant for such first-person judgment is derived from an explanatory theory constructed from the third-person perspective. Discussions in historical phenomenology can be treated as plain phenomenology. This is illustrated by a critical consideration of Brentano’s account of consciousness, drawing on some ideas in early Husserl. Dennett’s advocacy of heterophenomenology on the grounds of its supposed “neutrality” does not show (...) it is preferable to plain phenomenology. In fact the latter is more neutral in ways we ought to want, and permits a desirable use of first-person reflection that finds no place in the former. (shrink)

Humans can think about their conscious experiences using a special class of ?phenomenal? concepts. Psychophysical identity statements formulated using phenomenal concepts appear to be contingent. Kripke argued that this intuited contingency could not be explained away, in contrast to ordinary theoretical identities where it can. If the contingency is real, property dualism follows. Physicalists have attempted to answer this challenge by pointing to special features of phenomenal concepts that explain the intuition of contingency. However no physicalist account of their distinguishing (...) features has proven to be satisfactory. Leading accounts rely on there being a phenomenological difference between tokening a physical-functional concept and tokening a phenomenal concept. This paper shows that existing psychological data undermine that claim. The paper goes on to suggest that the recalcitrance of the intuition of contingency may instead by explained by the limited means people typically have for applying their phenomenal concepts. Ways of testing that suggestion empirically are proposed. (shrink)

Block’s well-known distinction between phenomenal consciousness and access consciousness has generated a large philosophical literature about putative conceptual connections between the two. The scientific literature about whether they come apart in any actual cases is rather smaller. Empirical evidence gathered to date has not settled the issue. Some put this down to a fundamental methodological obstacle to the empirical study of the relation between phenomenal consciousness and access consciousness. Block (2007) has drawn attention to the methodological puzzle and attempted to (...) answer it. While the evidence Block points to is relevant and important, this paper puts forward a more systematic framework for addressing the puzzle. To give it a label, the approach is to study phenomenal consciousness as a natural kind. The approach allows consciousness studies to move beyond the initial means of identifying instances of the kind, like verbal report, and to find its underlying nature. It is wellrecognised that facts about an underlying kind may allow identification of instances of the kind that do not match the initial means of identification (cp. non-liquid samples of water). This paper shows that the same method can be deployed to investigate phenomenal consciousness independently of access consciousness. (shrink)
