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 meta- physical 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 intro- specting 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 con- necting 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.

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)

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)

The idea of representation has been central in discussions of intentionality for many years. But only more recently has it begun playing a wider role in the philosophy of mind, particularly in theories of consciousness. Indeed, there are now multiple representational theories of consciousness, corresponding to different uses of the term "conscious," each attempting to explain the corresponding phenomenon in terms of representation. More cautiously, each theory attempts to explain its target phenomenon in terms of _intentionality_, and assumes that intentionality (...) is representation. (shrink)

Naive realism is one of the oldest theories of perception. To a first approximation, naive realism is the view that perception is a direct relation between a subject and an object. Many historical philosophers (from Locke to Russell) argued that naive realism must be rejected on the grounds that hallucinations are perceptual experiences without an object. Contemporary philosophers have resurrected the theory by insisting that genuine cases of perception have a different structure or a different metaphysical status than non-genuine ones. (...) This version of naive realism has come to be known as ‘disjunctivism’. Epistemological disjunctivism and disjunctivism about phenomenal belief, or what I shall call ‘Epistemological disjunctivism’, have also gained popularity in recent years. More recently disjunctivist accounts of bodily movements, abilities and reasons for action have entered the philosophical scene. This entry focuses on the contemporary debate about disjunctivism: its characterization, its motivation and its potential shortcomings. (shrink)

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)

This thesis explores the use of the concept 'realization' in the philosophy of mind. The primary focus is on the role realization plays in assessing or opposing identity theory. The history of the use of the concept of realization in the philosophy of mind is reviewed, and from that a set of desiderata to be used for assessing accounts of realization is extracted. The desiderata are applied to a sample account of realization proposed by Sydney Shoemaker. (2007) Next the application (...) of 'realization' in contemporary contexts is considered, focusing on the idea that mental kinds are, potentially, multiply realized. Based on interpretations of results from research in the relevant sciences this thesis considers two kinds of strategies used to object to multiple realization, (1) arguments against the concept of multiple realization: the Grain Argument (Bechtel and Mundale 1999), and Shapiro's Dilemma (Shapiro 2000), and (2) defeaters for alleged cases/examples of multiple realization proposed by Lawrence Shapiro and Thomas Polger: unification, individual differences, kind splitting, and abstraction and idealization. (Polger and Shapiro 2016) The thesis argues that, ultimately, these arguments hinge on the claim that there is no empirical evidence of multiply realized mental kinds. In response to this claim, the fourth chapter presents novel examples of multiple realization drawn from research in the cognitive neuroscience of language. There are three aspects from the study of language that are presented as examples of multiple realization: (1) language lateralization, (2) reading acquisition, and (3) second/multi- language learning. The analysis of these case studies applies Shoemaker's account of realization as a framework for describing the empirical data as cases of multiple realization. Objections to, and defeaters for, these cases are considered and rejected. The thesis concludes by raising the possibility that mental kinds are realized by mechanisms. This proposal involves drawing connections between traditional questions/views from the philosophy of mind with a current research program from the philosophy of science; the view is particularly important in the philosophy of neuroscience and the philosophy of biology, known as 'new mechanism'.

Frankish positions his view, illusionism about qualia (a.k.a. eliminativist physicalism), in opposition to what he calls radical realism (dualism and neutral monism) and conservative realism (a.k.a. non-eliminativist physicalism). Against radical realism, he upholds physicalism. But he goes along with key premises of the Gap Arguments for radical realism, namely, 1) that epistemic/explanatory gaps exist between the physical and the phenomenal, and 2) that every truth should be perspicuously explicable from the fundamental truth about the world; and he concludes that because (...) physicalism is true, there could be no phenomenal truths, and no qualia. I think he is wrong to accept 2); and even if he was right to accept it, the more plausible response would be not to deny the existence of qualia but to deny physicalism. In either case, denying the existence of qualia is the wrong answer. I present a physicalist realist alterative that refutes premise 2 of the Gap Argument; I also make a general case against the scientism that accompanies Frankish’s metaphysics. (shrink)

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.

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)

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)

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” there is an enthymeme in Wittgenstein’s private language argument 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 is upside down: we can only introspectively know what is going on inside our heads, after we learn of what is going on outside. 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 sensation 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 _ blue is the color that usually causes in 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.

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)

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)

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)

The Phenomenal Concept Strategy is a popular strategy used to support physicalism in the realm of conscious experience. This Strategy accounts for dualist intuitions but uses the ways in which we think about our experiences to explain these intuitions in a physicalist framework, without any appeal to ontological dualism. In this paper, I will raise two issues related to the currently available versions of the Phenomenal Concept Strategy. First, most of the theories belonging to the Phenomenal Concept Strategy posit that (...) phenomenal concepts are exceptional and sui generis concepts, and these theories can be shown to be largely ad hoc. Second, these theories may explain the existence of anti-physicalist intuitions, but they do not explain their persistence. My aim is to put forward a new theory of phenomenal concepts that can rise up to these challenges to the Phenomenal Concept Strategy. In my view, phenomenal concepts are not independent and sui generis concepts. On the contrary, they are closely related to our other epistemic concepts, especially our concepts of “justification”. Thinking about an experience means thinking about a specific kind of justification – an unjustified justification, or, in other words, an “ultimate seeming”. I will show why this explains the existence and the persistence of antiphysicalist intuitions in a non-ad hoc way. (shrink)
