The phenomenal concept strategy is considered a powerful response to anti-physicalist arguments. This physicalist strategy aims to provide a satisfactory account of dualist intuitions without being committed to ontological dualist conclusions. In this paper I first argue that physicalist accounts of phenomenal concepts fail to explain their cognitive role. Second, I develop an encapsulation account of phenomenal concepts that best explains their particularities. Finally, I argue that the encapsulation account, which features self-representing experiences, implies non-physical referents. Therefore, the account of (...) phenomenal concepts that has strong explanatory power does not explain away dualist intuitions—rather, it reinforces dualism. (shrink)

The aim of this paper is to assess the relationship between anti-physicalist arguments in the philosophy of mind and anti-naturalist arguments in metaethics, and to show how the literature on the mind-body problem can inform metaethics. Among the questions we will consider are: (1) whether a moral parallel of the knowledge argument can be constructed to create trouble for naturalists, (2) the relationship between such a "Moral Knowledge Argument" and the familiar Open Question Argument, and (3) how naturalists can respond (...) to the Moral Twin Earth argument. We will give particular attention to recent arguments in the philosophy of mind that aim to show that anti-physicalist arguments can be defused by acknowledging a distinctive kind of conceptual dualism between the phenomenal and the physical. This tactic for evading anti-physicalist arguments has come to be known as the Phenomenal Concept Strategy. We will propose a metaethical version of this strategy, which we shall call the `Moral Concept Strategy'. We suggest that the Moral Concept Strategy offers the most promising way out of these anti-naturalist arguments, though significant challenges remain. (shrink)

This paper advances a version of physicalism which reconciles the “a priori entailment thesis” (APET) with the analytic independence of our phenomenal and physical vocabularies. The APET is the claim that, if physicalism is true, the complete truths of physics imply every other truth a priori. If so, “cosmic hermeneutics” is possible: a demon having only complete knowledge of physics could deduce every truth about the world. Analytic independence is a popular physicalist explanation for the apparent “epistemic gaps” between phenomenal (...) and physical truths. The two are generally seen as incompatible, since the demon’s deductions seem to presuppose analytic connections between physical and phenomenal terms. I begin by arguing, in support of the APET, that implications from the complete truths of physics to phenomenal truths cannot be a posteriori. Such implications are (according to the physicalist) necessarily true. But they cannot be Kripke-style a posteriori necessities, since (according to the physicalist) the complete truths of physics fix any relevant a posteriori facts about the reference of terms. I then show how the physicalist can turn the tables: the demon can exploit the physical fixing of reference to bridge the gap between the vocabularies, by deducing when phenomenal and physical terms co-refer. This opens the way for a “type-C” physicalism, which accepts in-principle deducibility while still appealing to analytic independence to explain why we (who are not demons) find it impossible to see phenomenal-physical connections a priori.

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

During the last two decades, several different anti-physicalist arguments based on an epistemic or conceptual gap between the phenomenal and the physical have been proposed. The most promising physicalist line of defense in the face of these arguments – the Phenomenal Concept Strategy – is based on the idea that these epistemic and conceptual gaps can be explained by appeal to the nature of phenomenal concepts rather than the nature of non-physical phenomenal properties. Phenomenal concepts, on this proposal, involve unique (...) cognitive mechanisms, but none that could not be fully physically implemented. David Chalmers has recently presented a Master Argument to show that the Phenomenal Concept Strategy – not just this or that version of it, but any version of it – fails. Chalmers argues that the phenomenal concepts posited by such theories are either not physicalistically explicable, or they cannot explain our epistemic situation with regard to qualia. I argue that it is his Master Argument that fails. My claim is his argument does not provide any new reasons to reject the Phenomenal Concept Strategy. I also argue that, although the Phenomenal Concept Strategy is successful in showing that the physicalist is not rationally compelled to give up physicalism in the light of the anti-physicalist arguments, the anti-physicalist is not rationally compelled to give up the anti-physicalist argument in the light of the Phenomenal Concept Strategy either.

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

The German word Destruktion was used by Heidegger in the sense that philosophy should destroy some ontological concepts and the everyday meanings of certain words. Tradition allows the transmission of knowledge and sensations of continuity and connection with the past, but it must be critically evaluated so that it does not perpetuate certain prejudices. According to Heidegger, tradition transmits, but it also conceals. Tradition induces self-evidence and prevents us from accessing the origin of concepts. It makes us believe that we (...) do not need to return to that origin. Making tradition transparent dissolves the concealments it has provoked. Here I will apply this idea to the mental and the physical by suggesting that the mind-body problem has inherited occultations that are born in Descartes himself. As a result, what could be a new philosophical framework for the research in consciousness emerges: That as an individual cognitive being I cannot avoid splitting reality into what I am and what I am not, extending then the individual duality to a collective error transmitted culturally.

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)

This paper will be concerned with the role acquaintance plays in contemporary theories of introspection. Traditionally, the relation of acquaintance has been conceived in analytic epistemology and philosophy of mind as being only epistemically relevant inasmuch as it causes, or enables, or justifies a peculiar kind of propositional knowledge, i.e., knowledge by acquaintance. However, in recent years a novel account of the role of acquaintance in our introspective knowledge has been offered. According to this novel constitutive approach, acquaintance is, in (...) itself, a sui generis—i.e., non-propositional—kind of knowledge. As we will suggest, a stalemate between David Chalmers’ account of direct phenomenal concepts—as a prototypical example of a causal view—and Anna Giustina’s account of primitive introspection—as a prototypical example of a constitutive view—is looming in the current controversy between the two families of theories. Towards the end of the essay, we will point to some possible ways for a constitutive theorist to break the stalemate. (shrink)

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

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

This paper is a defense of the so-called phenomenal-concept strategy, based on a new view of phenomenal concepts as special de re modes of presentation of the phenomenal character of experience. Phenomenal concepts can be explained in physical terms as mental particulars (as phenomenal files) created in the individual’s mind to pick out the phenomenal character of experience by representing certain physical properties as those represented by the experiences themselves (metarepresentation). They are individuated by two fundamental relations: the perceptual (acquaintance) (...) relation the creature bears to the physical properties represented by its own experience and the relation the creature bears to itself (self-acquaintance) as the subject undergoing those experiences. Mary’s newly acquired phenomenal file presents the phenomenal character of her new experience of red by means of the new relation she bears to herself as the creature standing in the experiential relation to the color red.

Making an adequate aesthetic judgment about an object or an aesthetic property requires first-hand experience of that object or property. Many have suggested that this principle is a valid epistemic norm in the epistemology of the aesthetic. However, some recent philosophers have argued that certain works of conceptual art and other counterexamples disprove the principle in question, even suitably modified. In this paper, I argue that these philosophers are mistaken and that, when properly qualified, the acquaintance principle (in some of (...) its versions) is not threatened by their examples and arguments.

Panqualityism, recently defended by Sam Coleman, is a variety of Russellian monism on which the categorical properties of fundamental physical entities are qualities, or, in Coleman’s exposition, unconscious qualia. Coleman defends a quotationalist, higher-order thought version of panqualityism. The aim of this paper is, first, to demonstrate that a first-order representationalist panqualityism is also available, and to argue positively in its favor. For it shall become apparent that quotationalist and first-order representationalist panqualityism are, in spite of their close similarities, radically (...) different theories: quotationalist panqualityism locates qualities in the subject of an experience, while first-order panqualityism locates qualities in the world. I argue that this makes quotationalist panqualityism implausible and first-order, representationalist panqualityism a highly natural, elegant, and intuitive theory. (shrink)

Introspection is the capacity by which we know our own conscious mental states. Several theories aim to explain it. According to acquaintance theory, we know our experiences by being acquainted with them. Acquaintance is non-causal, non-inferential, and non-observational. I present a dilemma for the acquaintance theory of introspection. Either subjects are always acquainted with all their experiences; or some attentional mechanism selects the relevant experiences (or aspects of experiences) for introspection. The first option is implausible: it implies that subjects are (...) omniscient about their own experiences. The second option is also implausible: if acquaintance is a non-causal relation, introspection cannot target specific (aspects of) experiences without violating the principle of causal closure of the physical. (shrink)

Most recent philosophical theories of consciousness account for it in terms of representation, the bulk of the debate revolving around whether (suitably) representing something is sufficient for consciousness (as per first-order representationalism) or some further (meta-)representation is needed (as per higher-order representationalism and self-representationalism). In this paper, I explore an alternative theory of consciousness, one that aims to explain consciousness not in terms of representation but in terms of the epistemically and metaphysically direct relation of acquaintance. I call this the (...) Inner Acquaintance Theory of consciousness (IAT). Roughly, on IAT, what makes a mental state conscious is its subject being acquainted with it. Though not wholly unprecedented, IAT is still at the fringe of consciousness debates and remains largely underexplored. The main goal of this paper is to take some steps toward developing the details of IAT, illustrate its potential explanatory power, and put it forward as a plausible alternative to representational theories, with the hope that this will contribute to shifting IAT closer to the center of the debate. Here is how I proceed. In §2 I introduce a notion—inner awareness—that is crucial both to contextualize and to understand IAT. In §3 I provide some preliminary motivation for exploring IAT. In §4 I explain the notion of acquaintance and illustrate some of the features that are typically attributed to it in the literature. The details of IAT are then shaped through four main decision points. I address them in §§5-8, where I suggest a particular choice at each decision point, thereby progressively building up a view that I consider particularly promising. (shrink)

The primary goal of this paper is to provide substantial motivation for exploring an Acquaintance account of phenomenal consciousness, on which what fundamentally explains phenomenal consciousness is the relation of acquaintance. Its secondary goal is to take a few steps towards such an account. Roughly, my argument proceeds as follows. Motivated by prioritizing naturalization, the debate about the nature of phenomenal consciousness has been almost monopolized by representational theories. Among them, Self-Representationalism is by far the most antecedently promising. However, on (...) thorough inspection, Self-Representationalism turns out not explanatorily or theoretically better than the Acquaintance account. Indeed, the latter seems to be superior in at least some important respects. Therefore, at the very least, there are good reasons to take the Acquaintance account into serious consideration as an alternative to representational theories. The positive contribution of this paper is a sketch of an account of consciousness on which phenomenal consciousness is explained partly in representationalist terms, but where a crucial role is played by the relation of acquaintance.

In this paper, I present a two-pronged argument devoted to defending the type-identity theory of mind against the argument presented by Kripke in _Naming and Necessity_. In the first part, the interpersonal case, I show that since it is not possible to establish the metaphysical conditions for phenomenal identity, it is not possible to argue that there can be physical differences between two subjects despite their phenomenal identity. In the second part, the intrapersonal case, I consider the possibility of imagining (...) one and the same individual having the same phenomenal state while counterfactually being in very different physical states. I argue that this case should respect Kripke’s implicit theory of personal identity—but this proves to be a very difficult task to accomplish, thus preventing the argument from getting off the ground. Therefore, I maintain, that the type-identity theory is still the better option to solve the mind–body problem. (shrink)

Frank Jackson's case of Mary the colour scientist, and the knowledge argument against physicalism built upon it, are well known. This paper starts from Jackson's other, more neglected, thought experiment, about Fred, who sees a unique shade of red. It explores two senses in which properties are said to be 'objective', roughly corresponding to the ideas of a property's being intersubjectively accessible, on the one hand, and its being knowable without the need for special experiences, on the other. These senses (...) of the objective are contrasted, and their links to the doctrine of physicalism explored, and it is argued that, in the sense of objectivity we should embrace, mental qualities come out as objective and physical properties. The paper ends up by proposing a novel theory about how mental qualities fit into the world—as determinates of determinable physical properties, a view that is distinguished from the closely related 'Russellian monism'.

This paper is primarily about metaphysics; specifically, about a Cartesian view of the self, according to which it is a simple, enduring, non-material entity.I take a critical look at Nida-Rümelin’s novel conceptual arguments for this view and argue that they don’t give us decisive reasons to uphold the Cartesian view. But in Nida-Rümelin’s view, what is at stake in these arguments is not merely theoretical: the truth – and our beliefs about it – has practical consequences as well. In her (...) view, if the Cartesian simple view of the self were false, we would have no reason to love and care for family and friends, and our special interest in our own future would be pointless. In the last section of this paper, I will say something about the sense in which it is right and the sense in which it is wrong to think that the metaphysics of the self has broader relevance for our lives.

Epiphenomenalist dualists hold that certain physical states give rise to non-physical conscious experiences, but that these non-physical experiences are themselves causally inefficacious. Among the most pressing challenges facing epiphenomenalists is the so-called “paradox of phenomenal judgment”, which challenges epiphenomenalism’s ability to account for our knowledge of our own conscious experiences. According to this objection, we lack knowledge of the very thing that epiphenomenalists take physicalists to be unable to explain. By developing an epiphenomenalist theory of subjects and mental states, this (...) paper argues that there is nothing paradoxical or problematic about the epiphenomenalist’s understanding of phenomenal judgments or phenomenal self-knowledge. The appearance of paradox emerges from inconsistently combining (epiphenomenalist) dualism about qualia with a physicalistic conception of subjects of experience. The lesson we should take from this is not that there is anything wrong with epiphenomenalism, but that epiphenomenalist dualists should be “dualists all the way down”—embracing a picture of mind that gives phenomenology a central place, in its understanding of both subjects and their knowledge of their own minds. Epiphenomenalist-friendly accounts of reference and memory are also developed, showing that neither of these issues creates a paradox for the epiphenomenalist. (shrink)

Illusionism is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Many opponents to the thesis take it to be obviously false. They think that they can reject illusionism, even if they conceded that it is coherent and supported by strong arguments. David Chalmers has articulated this reaction to illusionism in terms of a “Moorean” argument against illusionism. This argument contends that illusionism is false, because it is obviously true that we have phenomenal experiences. I argue (...) that this argument fails by showing that its defenders cannot maintain that its crucial premise has the kind of support needed for the argument to work, without begging the question against illusionism.

Is it possible to build a conscious machine, an artifact that has qualitative experiences such as feeling pain, seeing the redness of a flower or enjoying the taste of coffee ? What makes such experiences conscious is their phenomenal character: it is like something to have such experiences. In contemporary philosophy of mind, the question of the qualitative aspect of conscious experiences is often addressed in terms of qualia. In a pre-theoretical and intuitive sense, qualia refer to the phenomenal character (...) or “what-it’s-like-ness” of a conscious experience: the painfulness of a pain experience or the redness of a visual experience of a red object. The problem of artificial qualia is the question of the theoretical possibility of the realization of qualia by artifacts. In this work, this problem will serve as a methodological tool to address what is arguably the most fundamental question of philosophy of mind: what exactly is consciousness? (shrink)

Introspective knowledge by acquaintance is knowledge we have by being directly aware of our phenomenally conscious states. In this paper, I argue that introspective knowledge by acquaintance is a sui generis kind of knowledge: it is irreducible to any sort of propositional knowledge and is wholly constituted by a relationship of introspective acquaintance. My main argument is that this is the best explanation of some epistemic facts about phenomenal consciousness and introspection. In particular, it best explains the epistemic asymmetry between (...) a subject who has never had a certain phenomenal state and one who has. I also consider two theoretical objections to my claim: an objection from disunity and an objection from mysteriousness. I show that these objections can be answered and that introspective knowledge by acquaintance being sui generis remains a live option on the table. (shrink)

In recent literature on the metaphysics of consciousness, and in particular on the prospects of physicalism, there are two interesting strands of discussion. One strand concerns the so-called ‘thesis of revelation’, the claim that the essences of phenomenal properties are revealed in experience. The other strand concerns the intuition of dualism, the intuition that consciousness is nonphysical. With a particular focus on the former, this paper advances two main arguments. First, it argues that the thesis of revelation is intuitive; it (...) is part of our ordinary, implicit conception of experience. Second, it brings the two strands of discussion together and puts forward a rational explanation of the intuition of dualism in terms of the intuitiveness of the thesis of revelation. (shrink)

In this paper, I develop a new version of the acquaintance view of the nature of introspection of phenomenal states. On the acquaintance view, when one introspects a current phenomenal state of one's, one bears to it the relation of introspective acquaintance. Extant versions of the acquaintance view neglect what I call the phenomenal modification problem. The problem, articulated by Franz Brentano in his Psychology from an Empirical Standpoint, is that drawing introspective attention to one's current conscious experience may modify (...) its phenomenology. Failing to take phenomenal modification into account affects the adequacy of extant versions of the acquaintance view. The purpose of this paper is to develop a better version, the integration account, that meets the phenomenal modification challenge while preserving the merits of other versions. (shrink)

Physicalism demands an explication of what it means for something to be physical. But the most popular way of providing one—viz., characterizing the physical in terms of the postulates of a scientifically derived physical theory—is met with serious trouble. Proponents of physicalism can either appeal to current physical theory or to some future physical theory (preferably an ideal and complete one). Neither option is promising: currentism almost assuredly renders physicalism false and futurism appears to render it indeterminate or trivial. The (...) purpose of this essay is to argue that attempts to characterize the mental encounter a similar dilemma: currentism with respect to the mental is likely to be inadequate or contain falsehoods and futurism leaves too many significant questions about the nature of mentality unanswered. This new dilemma, we show, threatens both sides of the current debate surrounding the metaphysical status of the mind. (shrink)

Why do we tend to think that phenomenal consciousness poses a hard problem? The answer seems to lie in part in the fact that we have the impression that phenomenal experiences are presented to us in a particularly immediate and revelatory way: we have a sense of acquaintance with our experiences. Recent views have offered resources to explain such persisting impression, by hypothesizing that the very design of our cognitive systems inevitably leads us to hold beliefs about our own experiences (...) with certainty. I argue against this kind of “designed certainty” views. First, I claim that it is doubtful that we really hold beliefs about our own experiences with certainty—in any sense of certainty that would make our phenomenal beliefs special. Second, I claim that, even if it were the case that we hold beliefs about experiences with certainty, this would fall short of explaining our sense of acquaintance. (shrink)

To be acquainted with something (in the philosophical sense of “acquainted” discussed here) is to be directly aware of it. The idea that we are acquainted with certain things we experience has been discussed throughout the history of Western Philosophy, but in the early 20th century it gained especially focused attention among analytic philosophers who drew their inspiration from Bertrand Russell's work on acquaintance. Since then, many philosophers—particularly those working on self‐knowledge or perception—have used the notion of acquaintance to explain (...) various facts about human experience and knowledge. In this paper, I offer an overview of this work, with particular focus on the resurgent literature on acquaintance in contemporary analytic philosophy. After more fully explaining what acquaintance is (or is supposed to be), I describe some reasons for thinking that we are indeed acquainted with certain things we experience, and then I survey some of the facts about experience and knowledge that acquaintance may help explain.

The aim of the paper is to recall Frank Jackson's 1982 knowledge argument and some prominent objections that were brought against it. Is there a new path we can take in order to bring something new to the table? Is the debate on the argument and its powerful conclusion over?

According to panqualityism, a form of Russellian monism defended by Sam Coleman and others, consciousness is grounded in fundamental qualities, i.e. unexperienced qualia. Despite panqualityism’s significant promise, according to David Chalmers panqualityism fails as a theory of consciousness since the reductive approach to awareness of qualities it proposes fails to account for the specific phenomenology associated with awareness. I investigate Coleman’s reasoning against this kind of phenomenology and conclude that he successfully shows that its existence is controversial, and so Chalmers’s (...) critique is inconclusive. I then present a critique of panqualityism that avoids this controversial posit, arguing that the panqualityist treatment of awareness faces an explanatory gap, failing to account for the intimate cognitive access to qualities which we are afforded, i.e. for our ‘strong awareness’ of qualities. The real worry for panqualityists is thus not the contested phenomenology of awareness, which Chalmers relies on, but rather the special way in which we are aware of qualities. (shrink)

Revelation, or the view that the essence of phenomenal properties is presented to us, is as intuitively attractive as it is controversial. It is notably at the core of defences of anti-physicalism. I propose in this paper a new argument against Revelation. It is usually accepted that low-level sensory phenomenal properties, like phenomenal red, loudness or brightness, stand in relation of similarity and quantity. Furthermore, these similarity and quantitative relations are taken to be internal, that is, to be fixed by (...) what their relata are. I argue that, under some plausible additional premises, no account of what grounds these relations in the essence of their relata is consistent with Revelation, at least if we take common phenomenological descriptions for granted. As a result, the plausibility of Revelation is undermined. One might however resist this conclusion by weakening the epistemic relation postulated between subjects and their phenomenal properties. (shrink)

In the philosophy of mind, revelation is the claim that the nature of qualia is revealed in phenomenal experience. In the literature, revelation is often thought of as intuitive but in tension with physicalism. While mentions of revelation are frequent, there is room for further discussion of how precisely to formulate the thesis of revelation and what it exactly amounts to. Drawing on the work of David Lewis, this paper provides a detailed discussion on how the thesis of revelation, as (...) well as its incompatibility with physicalism, is to be understood. (shrink)

According to the scrutability argument against physicalism, an a priori gap between the physical and conscious experience entails a lack of necessitation and the falsity of physicalism. This paper investigates the crucial premise of the scrutability argument: the inference from an a priori gap to a lack of necessitation. This premise gets its support from modal rationalism, according to which there are important, potentially constitutive, connections between a priori justification and metaphysical modality. I argue against the strong form of modal (...) rationalism that underwrites the scrutability argument and suggest a more moderate rationalist view. I offer a novel demonstrative reply to the scrutability argument, according to which demonstratives play a vital role in the generation of meaning for our representations of conscious experience. This connection between conscious experience and demonstratives, rather than a metaphysical gap generated by the truth of dualism, is the source of the epistemic gap between consciousness and the physical.

This is the introductory essay to the collection of essays: 'Acquaintance: New Essays' (eds. Knowles & Raleigh, forthcoming, OUP). In this essay I provide some historical background to the concept of acquaintance. I examine various Russellian theses about acquaintance that contemporary acquaintance theorists may wish to reject. I consider a number of questions that acquaintance theorists face. I provide a survey of current debates in philosophy where acquaintance has recently been invoked. And I also provide brief summaries of the other (...) essays in this volume. (shrink)

Illusionism about phenomenal consciousness is the thesis that phenomenal consciousness does not exist, even though it seems to exist. This thesis is widely judged to be uniquely counterintuitive: the idea that consciousness is an illusion strikes most people as absurd, and seems almost impossible to contemplate in earnest. Defenders of illusionism should be able to explain the apparent absurdity of their own thesis, within their own framework. However, this is no trivial task: arguably, none of the illusionist theories currently on (...) the market is able to do this. I present a new theory of phenomenal introspection and argue that it might deal with the task at hand. (shrink)

Many philosophers have tried to defend physicalism concerning phenomenal consciousness, by explaining dualist intuitions within a purely physicalist framework. One of the most common strategies to do so consists in interpreting the alleged “explanatory gap” between phenomenal states and physical states as resulting from a fallacy, or a cognitive illusion. In this paper, I argue that the explanatory gap does not rest on a fallacy or a cognitive illusion. This does not imply the falsity of physicalism, but it has consequences (...) on the kind of physicalism we should embrace. (shrink)

The majority of physicalists are type-B physicalists – believing that the phenomenal-physical truths are only knowable a posteriori. This paper aims to show why this view is misguided. The strategy is to design an agent who (1) has full general physical knowledge, (2) has phenomenal concepts, and yet (3) is wired such that she would be in a position to immediately work out the phenomenal-physical truths. I argue that this derivation yields a priori knowledge. The possibility of such a creature (...) entails that – contrary to type-B physicalism – there is not an ideal epistemic gap between the phenomenal and the physical truths. Out of this argument against type-B physicalism emerges a positive result: a new and compelling version of type-A physicalism, roughly a type-A phenomenal concept strategy. (shrink)

It is often said that normative properties are “just too different” to reduce to other kinds of properties. This suggests that many philosophers find it difficult to believe reductive theses in ethics. I argue that the distinctiveness of the normative concepts we use in thinking about reductive theses offers a more promising explanation of this psychological phenomenon than the falsity of Reductive Realism. To identify the distinctiveness of normative concepts, I use resources from familiar Hybrid views of normative language and (...) thought to develop a Hybrid view of normative concepts. In addition to using this new Hybrid view to explain why reductive theses are difficult to believe, I show how to preserve several patterns of inference involving normative concepts that, intuitively, it is possible to make, and hence answer an important recent challenge to Hybrid views from Mark Schroeder.

Illusionism about consciousness is the thesis that phenomenal consciousness does not exist, but merely seems to exist. Embracing illusionism presents the theoretical advantage that one does not need to explain how consciousness arises from purely physical brains anymore, but only to explain why consciousness seems to exist while it does not. As Keith Frankish puts it, illusionism replaces the “hard problem of consciousness” with the “illusion problem.” However, a satisfying version of illusionism has to explain not only why the illusion (...) of consciousness arises, but also why it arises with its particular strength: Notably, why we are so deeply reluctant to recognize the illusory nature of consciousness. Explaining our strong intuitive resistance to illusionism means solving what I call the “illusion meta-problem,” which I think is a part of the illusion problem. In this paper, I argue that current versions of illusionism are unable to solve the illusion meta-problem. I focus on two of the most promising recent illusionist theories of consciousness, and I show why they fail to explain the peculiar reluctance we encounter whenever we try to accept that consciousness is an illusion.

This dissertation contains four independent essays addressing a cluster of related topics in the philosophy of mind. Chapter 1: “Fundamentality Physicalism” argues that physicalism can usefully be conceived of as a thesis about fundamentality. The chapter explores a variety of other potential formulations of physicalism (particularly modal formulations), contrasts fundamentality physicalism with these theses, and offers reasons to prefer fundamentality physicalism over these rivals. Chapter 2:“Modal Rationalism and the Demonstrative Reply to the Master Argument Against Physicalism” introduces the Master Argument (...) Against Physicalism and investigates its crucial premise: the inference from an a priori gap between the physical and consciousness to a lack of necessitation between the two. I argue against the strong form of modal rationalism that underwrites the master argument and offer a more moderate rationalist view. I offer a novel demonstrative reply to the master argument, according to which a connection between conscious experience and demonstratives, not dualism, is the source of the epistemic gap between consciousness and the physical. Chapter 3: “Conceptual Mastery and the Knowledge Argument” argues that Frank Jackson’s famous anti-physicalist knowledge argument featuring Mary, a brilliant neuroscientist raised in a black and white room, founders on a dilemma. Either (i) Mary cannot know the relevant experiential truths because of trivial obstacles that have no bearing on the truth of physicalism or (ii) once the obstacles have been removed, Mary can know the relevant truths. Chapter 4: “Toward a Theory of Conceptual Mastery” investigates the question “Under what conditions does a thinker fully understand, or have mastery of, a concept?” I argue against three views of conceptual mastery, according to which conceptual mastery is a matter of holding certain beliefs, being disposed to make certain inferences, or having certain intuitions. I propose and respond to objections to my own “meaning postulate view” of the conditions under which a thinker has mastery of a concept. (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)

This article aims to show that Williamson's anti-luminosity argument does not succeed if we presuppose a constitutive connection between the phenomenal and the doxastic. In contrast to other luminists, however, my strategy is not to critically focus on the refined safety condition in terms of degrees of confidence that anti-luminists typically use in this context. Instead, I will argue that, given a certain conception of what Chalmers calls ‘direct phenomenal concepts,’ luminosity is guaranteed even if the refined safety condition in (...) terms of degrees of confidence is taken for granted.
