Standard responses to the knowledge argument grant that Mary could know all of the physical facts even while trapped inside her black‐and‐white room. What they deny is that upon leaving her black‐and‐white room and experiencing red for the first time, Mary learns a genuinely new fact. This paper develops an alternate response in a grounding physicalist framework, on which Mary does not know all of the physical facts while trapped inside the room. The main thesis is that Mary does not (...) know certain phenomenal facts while trapped inside the room, whereby these facts classify as physical due to being wholly and fully metaphysically grounded in the underlying fundamental facts which are themselves entirely physical.

According to orthodox views of philosophical methodology, when philosophers appeal to intuitions, they treat them as evidence for their contents. Call this “descriptive evidentialism.” Descriptive evidentialism is assumed both by those who defend the epistemic status of intuitions and by those, including many experimental philosophers, who criticize it. This article shows, however, that the idea that philosophers treat intuitions as evidence struggles to account for the way philosophers treat intuitions in a variety of philosophical contexts. In particular, it cannot account (...) for philosophers' treatment of a priori intuitions, for nonpropositional uses of intuition, and for philosophers' failure to use intuition to exclude the counterintuitive. The article concludes that alternatives to descriptive evidentialism (some of which are sketched) must be developed, and that much of the recent debate between traditionalists and skeptics from, for example, experimental philosophy is probably based on a false presupposition.

In this paper I discuss a variant of the knowledge argument which is based upon Frank Jackson's Mary thought experiment. Using this argument, Jackson tries to support the thesis that a purely physical – or, put generally: an objectively scientific – perspective upon the world excludes the important domain of `phenomenal' facts, which are only accessible introspectively. Martine Nida-Rümelinhas formulated the epistemological challenge behind the case of Mary especially clearly. I take her formulation of the problem as a starting-point and (...) present a solution which is based solely on the concepts of capability and of metalinguistic beliefs. References to epiphenomenal facts, phenomenal knowledge etc. will be avoided completely. I specify my proposal against the backdrop of Burge's critical reflections about metalinguistic reinterpretation of expressions of belief and the externalist thesis held by Burge, Putnam and others that meanings and mental states are dependent upon the environment. My solution is then compared with Lewis' and Nemirow's ability objection. Finally I argue that the much discussed ``knowing what it is like'' has in its ordinary meaning nothing much to do with `phenomenal knowledge' or knowledge of `epiphenomenal' facts. (shrink)

The analogy between gustatory taste and critical or aesthetic taste plays a recurring role in the history of aesthetics. Our interest in this article is in a particular way in which gustatory judgments are frequently thought to be analogous to critical judgments. It appears obvious to many that to know how a particular object tastes we must have tasted it for ourselves; the proof of the pudding, we are all told, is in the eating. And it has seemed just as (...) obvious to many philosophers that aesthetic judgment requires first-person experience. In this article we argue that, despite its initial appeal, the claim that gustatory and critical judgments are analogous in this way is mistaken. The two sorts of judgments are, as a matter of fact, similar in their epistemology, but earlier theorists have got things entirely backward—neither gustatory judgment nor aesthetic judgment requires first-hand acquaintance with their objects. Our particular focus in this article is on arguing that first-person experience is not required to know how an item of food or drink tastes. In fact, there are a wide variety of ways in which we can acquire this knowledge. (shrink)

I assume that there exists a general phenomenon, the phenomenon of the explanatory gap, surrounding consciousness, normativity, intentionality, and more. Explanatory gaps are often thought to foreclose reductive possibilities wherever they appear. In response, reductivists who grant the existence of these gaps have offered countless local solutions. But typically such reductivist responses have had a serious shortcoming: because they appeal to essentially domain-specific features, they cannot be fully generalized, and in this sense these responses have been not just local but (...) parochial. Here I do better. Taking for granted that the explanatory gap is a genuine phenomenon, I offer a fully general diagnosis that unifies these previously fragmented reductivist responses. (shrink)

Three big philosophical problems about consciousness are: Why does it exist? How do we explain and understand it? How can we explain brain-consciousness correlations? If functionalism were true, all three problems would be solved. But it is false, and that means all three problems remain unsolved (in that there is no other obvious candidate for a solution). Here, it is argued that the first problem cannot have a solution; this is inherent in the nature of explanation. The second problem is (...) solved by recognizing that (a) there is an explanation as to why science cannot explain consciousness, and (b) consciousness can be explained by a different kind of explanation, empathic or “personalistic” explanation, compatible with, but not reducible to, scientific explanation. The third problem is solved by exploiting David Chalmers“principle of structural coherence”, and involves postulating that sensations experienced by us–visual, auditory, tactile, and so on–amount to minute scattered regions in a vast, multi dimensional “space” of all possible sensations, which vary smoothly, and in a linear way, throughout the space. There is also the space of all possible sentient brain processes. There is just one, unique one-one mapping between these two spaces that preserves continuity and linearity. It is this which provides the explanation as to why brain processes and sensations are correlated as they are. I consider objections to this unique-matching theory, and consider how the theory might be empirically confirmed. (shrink)

Qualia are phenomenal properties of sensations and perceptual states: they are whatever it is that gives such states their “felt,” qualitative character. (In speaking of sensations, I speak of course not of mental objects or mental contents, but of mental events—of sensings, not sensa.).

This essay interrogates recent materialist monisms, be they based on contingency, eliminativism, or objective phenomenology, on account of their metaphilosophical ramifications. It is argued that certain dualities must be retained, at least nominally, in order to have any explanatory purchase and escape velocity from philosophical circularity. Dyads such as “spirit” and “matter,” “manifest” and “scientific,” “living” and “dead,” or even “illusion” and “reality” are given an immanentist reading that treats them as equal parts of the Real. Following this revisionary metaphysics (...) that reviews the meaning of such terms as optical realities, the matter–spirit couple is specifically used to explain why reality cannot appear as just one thing, even if only in virtue of the illusion of at least two things. The consequences for philosophical monisms of all types, and for anthropocentric thought in general, are then examined in the light of the ethical effects of recent attempts to explain every thing through one medium alone.

O'Brien & Opie's (O&O's) theory demands a view of unconscious processing that is incompatible with virtually all current PDP models of neural activity. Relative to the alternatives, the theory is closer to an AI than a parallel distributed processing (PDP) perspective, and its treatment of phenomenology is ad hoc. It raises at least one important question: Could features of network relaxation be the “switch” that turns an unconscious into a conscious network?

Many have urged that the biggest obstacles to a physicalistic understanding of consciousness are the problems raised in connection with the subjectivity of consciousness. These problems are most acutely expressed in consideration of the knowledge argument against physicalism. I develop a novel account of the subjectivity of consciousness by explicating the ways in which mental representations may be perspectival. Crucial features of my account involve analogies between the representations involved in sensory experience and the ways in which pictorial representations exhibit (...) perspectives or points of view. I argue that the resultant account of subjectivity provides a basis for the strongest response physicalists can give to the knowledge argument. (shrink)

Unlike those with type 1 blindsight, people who have type 2 blindsight have some sort of consciousness of the stimuli in their blind field. What is the nature of that consciousness? Is it visual experience? I address these questions by considering whether we can establish the existence of any structural—necessary—features of visual experience. I argue that it is very difficult to establish the existence of any such features. In particular, I investigate whether it is possible to visually, or more generally (...) perceptually, experience form or movement at a distance from our body, without experiencing colour. The traditional answer, advocated by Aristotle, and some other philosophers, up to and including the present day, is that it is not and hence colour is a structural feature of visual experience. I argue that there is no good reason to think that this is impossible, and provide evidence from four cases—sensory substitution, achomatopsia, phantom contours and amodal completion—in favour of the idea that it is possible. If it is possible then one important reason for rejecting the idea that people with type 2 blindsight do not have visual experiences is undermined. I suggest further experiments that could be done to help settle the matter. (shrink)

The human enhancement debate has over the last few decades been concerned with ethical issues in methods for improving the physical, cognitive, or emotive states of individual people, and of the human species as a whole. Arguments in favour of enhancement defend it as a paradigm of rationality, presenting it as a clear-eyed, logical defence of what we stand to gain from transcending the typical limits of our species. If these arguments are correct, it appears that adults should in principle (...) be able to make rational and informed decisions about enhancing themselves. In this paper, however, we suggest that a rational and informed choice to enhance oneself may in some cases be impossible. Drawing on L. A. Paul’s work on ‘transformative experience’, we argue that some enhancements—such as certain moral or cognitive modifications—may give rise to unbridgeable epistemic gaps in key domains. Importantly, such gaps could prove to be not merely contingently unbridgeable due to a lack of information at a given moment, but radically unbridgeable, making someone in a non-enhanced state inherently unable to conceive of what it would be like to be enhanced in a particular way. Where this experience is key to understanding what values are being pursued by the enhancement itself, it may prove impossible for a person to be sufficiently informed, and to make a rational decision about whether or not to enhance herself. This poses a challenge for human enhancement proponents in general, and for transhumanists in particular. (shrink)

In two recent publications I argued against Nemirow and Lewis that there is distinctive, irreducibly phenomenal and perspectival information of the sort alleged by Jackson; but I gave an account of such information that is entirely compatible with a materialist view of human subjects. Hershfield argues that the latter account is inadequate, in that it fails to support the claim that the information it characterizes is irreducibly phenomenal or perspectival. I reply that Hershfield's conclusion does not follow from his argument's (...) premises. (shrink)

Intentionality is a mark of the mental, as Brentano (1874) noted. Any representation or conception of anything has the feature of intentionality, which informally put, is the feature of being about something that may or may not exist. Visual artworks are about something, whether something literal or abstract. The artwork is a mentalized physical object. Aesthetic experience of the artwork illustrates the nature of intentionality as we focus attention on the phenomenology of the sensory exemplar. This focus of attention on (...) the exemplar in aesthetic experience simultaneously exhibits what the intentional object is like and what our conception of it is like. The exemplar is Janus-faced, looking in one direction outward toward the objects conceived and in the other direction inward toward our conceiving of them. It shows us what intentionality is like and how we know it. (shrink)

In this paper, we describe four broad ‘meta-methods’ employed in scientific and philosophical research of qualia. These are the theory-centred metamethod, the property-centred meta-method, the argument-centred meta-method, and the event-centred meta-method. Broadly speaking, the theory-centred meta-method is interested in the role of qualia as some theoretical entities picked out by our folk psychological theories; the property-centred meta-method is interested in some metaphysical properties of qualia that we immediately observe through introspection ; the argument-centred meta-method is interested in the role of (...) qualia in some arguments for non-physicalism; the event-centred metamethod is interested in the role of qualia as some natural events whose nature is hidden and must be uncovered empirically. We will argue that the event-centred metamethod is the most promising route to a comprehensive scientific conception of qualia because of the flexibility of ontological and methodological assumptions it can provide. We also reveal the hidden influences of the different meta-methods and in doing so show why consideration of meta-methods has value for the study of consciousness. (shrink)

L. A. Paul’s Transformative Experience makes the claim that many important life decisions are epistemically and personally transformative in a way that does not allow us to assign subjective values to their outcomes. As a result, we cannot use normative decision theory to make such decisions rationally, or when we modify it to do so, decision theory leads us to choose in a way that is in tension with our authenticity. This paper examines Paul’s version of decision theory, and whether (...) this version in fact admits of the challenge she wants to raise. I focus on her psychological realist view of utilities and beliefs and her notion of rational, authentic preferences as informed by imaginative acquaintance. I argue that Paul fails to engage critically with traditional accounts of decision theory and, on closer inspection, it is not clear that her version of decision theory entails a tension between rational and authentic choice. More importantly, I argue that if her contribution is instead to bring to light the importance of authenticity alongside rational decision-making, the definition she provides of authenticity in fact undermines her argument.

The hard problem of consciousness has held center stage in the philosophy of mind for the past two decades. It claims that the phenomenal character of conscious experiences—what it’s like to be in them—cannot be explained by appeal to the operation of physiological subsystems. The hard problem arises, however, only given the assumption that hylomorphism is false. Hylomorphism claims that structure is a basic ontological and explanatory principle. A human is not a random collection of physical materials, but an individual (...) composed of physical materials with a structure that accounts for what it is and what it can do—the powers it has. What is true of humans is true of their activities as well. The latter are not random physiological changes, but structured ones: we engage in them by coordinating the ways our parts manifest their powers. Structured activities include perceptual experiences. Consequently, everything about a perceptual experience, including its phenomenal character, can be explained by describing the perceiver’s perceptual subsystems, the powers of those subsystems, and the coordination that unifies their activities into the activity of the perceiver as a whole. Conscious experiences thus fit unproblematically into the natural world—just as unproblematically as the phenomenon of life. Even exponents of the hard problem of consciousness agree that there is no hard problem of life. Consequently, if hylomorphism is true, there can be no hard problem of consciousness. To insist that there is such a problem, then, is implicitly to reject hylomorphism. The concept of consciousness that motivates the hard problem is as much a theoretical construct, therefore, as the concept of life that motivates an obstinate vitalist. (shrink)

In the book, I provide an account of what it is for an agent to have an ability. According to the Success View, abilities are all about success across possible situations. In developing and applying the view, the book elucidates the relation between abilities on the one hand and possibility, counterfactuals, and dispositions on the other; it sheds light on the distinction between general and specific abilities; it offers an understanding of degrees of abilities; it explains which role intentions and (...) performances play for the having of an ability, how abilities relate to success and failure, and gives an outlook at how the view might be applied to the free will debate and time travel.

Most ?theories of consciousness? are based on vague speculations about the properties of conscious experience. We aim to provide a more solid basis for a science of consciousness. We argue that a theory of consciousness should provide an account of the very processes that allow us to acquire and use information about our own mental states ? the processes underlying introspection. This can be achieved through the construction of information processing models that can account for ?Type-C? processes. Type-C processes can (...) be specified experimentally by identifying paradigms in which awareness of the stimulus is necessary for an intentional action. The Shallice (1988b) framework is put forward as providing an initial account of Type-C processes, which can relate perceptual consciousness to consciously performed actions. Further, we suggest that this framework may be refined through the investigation of the functions of prefrontal cortex. The formulation of our approach requires us to consider fundamental conceptual and methodological issues associated with consciousness. The most significant of these issues concerns the scientific use of introspective evidence. We outline and justify a conservative methodological approach to the use of introspective evidence, with attention to the difficulties historically associated with its use in psychology. (shrink)

Both a priori physicalism and a posteriori physicalism combine a metaphysical and an epistemological thesis. They agree about the metaphysical thesis: our world is wholly physical. Most agree that this requires everything that there is must be necessitated by the sort of truths described by physics. If we call the conjunction of the basic truths of physics P, all physicalists agree that P entails for any truth Q. Where they disagree is whether or not this entailment can be known a (...) priori. The a priori physicalist says it can, the a posteriori physicalist says it cannot. Though a posteriori physicalism is probably the dominant view, it is really a surprising and somewhat unlikely stance. In this article, the nature of the view is discussed, and two arguments are presented that should cause us to look again at the potential of a priori physicalism. (shrink)

The paper argues that Jackson's knowledge argument fails to undermine physicalist ontology. First, it is argued that, as this argument stands, it begs the question. Second, it is suggested that by supplementing the argument , this flaw can be remedied insofar as the argument is taken to be an argument against type-physicalism; however, this flaw cannot be remedied insofar as the argument is taken to be an argument against token-physicalism. The argument cannot be supplemented so as to show that experiences (...) have properties which are illegitimate from a physicalist perspective. (shrink)

David Lewis's account of the de se has two parts. The first part involves treating the objects of the attitudes, not as propositions but as properties. The second part involves treating our attitude to these properties as that of self‐ascription. In particular, much recent literature has tried to incorporate his account simply by treating the objects of the attitudes as centered worlds, where a centered world is an ordered pair of a possible world together with a spatiotemporal location. The explanation (...) of the account in terms of centered worlds originates with Lewis himself, in his development of some comments from Quine. This chapter examines some of other potential costs of Lewis's approach, those that stem from the idea of primitive self‐ascription. Lewis's account of the de se is both more radical, and more unintuitive, than has been appreciated. (shrink)

A popular defense of physicalist theories of consciousness against anti-physicalist arguments invokes the existence of ‘phenomenal concepts’. These are concepts that designate conscious experiences from a first person perspective, and hence differ from physicalistic concepts; but not in a way that precludes co-referentiality with them. On one version of this strategy phenomenal concepts are seen as (1) type demonstratives that have (2) no mode of presentation. However, 2 is possible without 1-call this the ‘bare recognitional concept’ view-and I will argue (...) that this avoids certain recent criticisms while retaining the virtue of finessing the ‘mode of presentation’ problem for phenomenal concepts. But construing phenomenal concepts this way seems to not do justice to the phenomenology of conscious experience. In this paper I examine whether or not this impression can be borne out by a good argument. As it turns out, it is harder to do so than one might think. It can be done, but it involves somewhat more convoluted reasoning than one might have supposed necessary. Having shown that, I will end with a few brief remarks on what my argument means for attempts to preserve a physicalist account of consciousness. (shrink)

Any position that promises genuine progress on the mind-body problem deserves attention. Recently, Daniel Stoljar has identified a physicalist version of Russells notion of neutral monism; he elegantly argues that with this type of physicalism it is possible to disambiguate on the notion of physicalism in such a way that the problem is resolved. The further issue then arises of whether we have reason to believe that this type of physicalism is in fact true. Ultimately, one needs to argue for (...) this position by inference to the best explanation, and I show that this new type of physicalism does not hold promise of more explanatory prowess than its relevant rivals, and that, whether it is better than its rivals or not, it is doubtful whether it would furnish us with genuine explanations of the phenomenal at all.

I identify one particular strand of thought in Thomas Nagel's ‘What Is It Like to Be a Bat?’, which I think has helped shape a certain conception of perceptual consciousness that is still prevalent in the literature. On this conception, perceptual consciousness is to be explained in terms of a special class of properties perceptual experiences themselves exhibit. I also argue that this conception is in fact in conflict with one of the key ideas that supposedly animates Nagel's argument in (...) ‘What Is It Like to Be a Bat?', which is the idea of an intimate connection between the idea of consciousness and that of a point of view.

This paper aims to outline, and argue for, an approach to episodic memory broadly in the spirit of knowledge-first epistemology. I discuss a group of influential views of epsiodic memory that I characterize as ‘two-factor accounts’, which have both proved popular historically and have also seen a resurgence in recent work on the philosophy of memory. What is common to them is that they try to give an account of the nature of episodic memory in which the concept of knowledge (...) plays no explanatory role. I highlight some parallels between these two-factor accounts and attempts to give a reductive definition of knowledge itself. I then discuss some problems two-factor accounts of episodic memory face in explaining the distinctive sense in which episodic recollection involves remembering personally experienced past events, before sketching an alternative approach to episodic memory, which takes as basic the idea that episodic memory involves the retention of knowledge. I argue that we can give an exhaustive constitutive account of what episodic memory is, and how it differs from other types of mental states, by considering what particular type of knowledge is retained in episodic memory, and what exactly having that knowledge consists in.

I discuss the meaning of 'There's something e is like', in the context of a reply to Eric Lormand's 'The explanatory stopgap'. I argue that Lormand is wrong to think it has a specially perceptual meaning. Rather, it has one of at least four candidate meanings: e is some way as regards its subject; e is some way and e's being that way is in the possession of its subject; e is some way in the awareness of its subject; e's (...) subject is the "experiencer" of e. I provide additional argumentation for the view in this paper that in the context, 'like this' functions as a predicate variable. (shrink)

The debate about the nature of knowledge-how is standardly thought to be divided between intellectualist views, which take knowledge-how to be a kind of propositional knowledge, and anti-intellectualist views, which take knowledge-how to be a kind of ability. In this paper, I explore a compromise position—the interrogative capacity view—which claims that knowing how to do something is a certain kind of ability to generate answers to the question of how to do it. This view combines the intellectualist thesis that knowledge-how (...) is a relation to a set of propositions with the anti-intellectualist thesis that knowledge-how is a kind of ability. I argue that this view combines the positive features of both intellectualism and anti-intellectualism. (shrink)

Emotions, I will argue, involve two kinds of feeling: bodily feeling and feeling towards. Both are intentional, in the sense of being directed towards an object. Bodily feelings are directed towards the condition of one's body, although they can reveal truths about the world beyond the bounds of one's body – that, for example, there is something dangerous nearby. Feelings towards are directed towards the object of the emotion – a thing or a person, a state of affairs, an action (...) or an event; such emotional feelings involve a special way of thinking of the object of the emotion, and I draw an analogy with Frank Jackson's well-known knowledge argument to show this. Finally, I try to show that, even if materialism is true, the phenomenology of emotional feelings, as described from a personal perspective, cannot be captured using only the theoretical concepts available for the impersonal stance of the sciences.

This paper calls into question the viability of materialist reduction of the phenomenal. I revisit the 'Knowledge Argument', which claims that there is information about the phenomenal which is not reducible to, nor even inferable from, information about the physical. I demonstrate the failure of the two chief strategies for blocking the Knowledge Argument: analyzing phenomenal knowledge as an ability, and construing it as knowledge of facts which are ontologically reducible to physical facts. Materialist reduction of the phenomenal is, thus, (...) untenable; materialists must adopt a more extreme, eliminativist view about the phenomenal. (shrink)

The aim of this paper is to reinforce anti-physicalism by extending the hard problem to a specific kind of intentional states. For reaching this target, I investigate the mental content of the new intentional states of Jackson’s Mary. I proceed in the following way: I start analyzing the knowledge argument, which highlights the hard problem tied to phenomenal consciousness. In a second step, I investigate a powerful physicalist reply to this argument: the phenomenal concept strategy. In a third step, I (...) propose a constitutional account of phenomenal concepts that captures the Mary scenario adequately, but implies anti-physicalist referents. In a last step, I point at the ramifications constitutional phenomenal concepts have on the constitution of Mary’s new intentional states. Therefore, by focusing the attention on phenomenal concepts, the so-called hard problem of consciousness will be carried over to the alleged easy problem of intentional states as well. (shrink)

In recent years the 'zombie argument' has come to occupy a central role in the case against physicalist views of consciousness, in large part because of the powerful advocacy it has received from David Chalmers.1 In this paper I seek to neutralize it by showing that a parallel argument can be run for physicalism, an argument turning on the conceivability of what I shall call anti-zombies. I shall argue that the result is a stand-off, and that the zombie argument offers (...) no independent reason to reject physicalism. (shrink)

Ambitious higher-order theories of consciousness aim to account for conscious states when these are understood in terms of what-it-is-like-ness. This paper considers two arguments concerning this aim, and concludes that ambitious theories fail. The misrepresentation argument against HO theories aims to show that the possibility of radical misrepresentation—there being a HO state about a state the subject is not in—leads to a contradiction. In contrast, the awareness argument aims to bolster HO theories by showing that subjects are aware of all (...) their conscious states. Both arguments hinge on how we understand two related notions which are ubiquitous in discussions of consciousness: those of what-it-is-like-ness and there being something it is like for a subject to be in a mental state. This paper examines how HO theorists must understand the two crucial notions if they are to reject the misrepresentation argument but assert the awareness argument. It shows that HO theorists can and do adopt an understanding—the HO reading—which seems to give them what they want. But adopting the HO reading changes the two arguments. On this reading, the awareness argument tells us nothing about those states there is something it is like to be in, and so offers no support to ambitious HO theories. And to respond to the misrepresentation understood according to the HO reading is to simply ignore the argument presented, and so to give no response at all. As things stand, we should deny that HO theories can account for what-it-is-like-ness. (shrink)

The purpose of this paper is to discuss Stanley and Williamson’s take on Ryle’s argument against know-how being know-that. For this, I provide an initial consideration of the possibility of isolating Ryle’s argument from his overall philosophical outlook and Stanley and Williamson’s purpose in their discussion of Ryle. I then examine in detail Stanley and Williamson’s reconstruction of Ryle’s argument with the specific aim of showing where they have introduced extraneous elements: I examine what they take to bes additional assumptions (...) needed for the argument to be valid and how they construct the premises in order to attempt to show that Ryle's argument is not sound. I end the paper showing the limits of Stanley and Williamson’s attack, suggesting how the extraneous elements Stanley and Williamson introduce already bias the discussion against Ryle. The main aim is not to defend a form of Ryle’s regress but rather advocate the need for a deeper discussion of Ryle’s views of mind and action when discussing his views on know-how. (shrink)

In an influential paper, L. A. Paul argues that one cannot rationally decide whether to have children. In particular, she argues that such a decision is intractable for standard decision theory. Paul's central argument in this paper rests on the claim that becoming a parent is ``epistemically transformative''---prior to becoming a parent, it is impossible to know what being a parent is like. Paul argues that because parenting is epistemically transformative, one cannot estimate the values of the various outcomes of (...) a decision whether to become a parent. In response, we argue that it is possible to estimate the value of epistemically transformative experiences. Therefore, there is no special difficulty involved in deciding whether to undergo epistemically transformative experiences. Insofar as major life decisions do pose a challenge to decision theory, we suggest that this is because they often involve separate, familiar problems. (shrink)

Strawson (1994) and Peacocke (1992) introduced thought experiments that show that it seems intuitive that there is, in some way, an experiential character to mental events of understanding. Some (e.g., Siewert 1998, 2011; Pitt 2004) try to explain these intuitions by saying that just as we have, say, headache experiences and visual experiences of blueness, so too we have experiences of understanding. Others (e.g., Prinz 2006, 2011; Tye 1996) propose that these intuitions can be explained without positing experiences of understanding. (...) Call this the debate between Realism and Anti-Realism about experiences of understanding. This paper aims to advance that debate in two ways. In the first half, I develop more precise characterizations of what Realists and Anti-Realists propose. In the second half, I distinguish the four most plausible versions of Anti-Realism and argue that Realism better explains the target intuition than any of them does. (shrink)

The aim of this paper is to critically assess and respond to two objections advanced by Daniel Stoljar against the so-called phenomenal concept strategy. My goal is to defend the physicalist response to both the knowledge argument and the conceivability argument against Stoljar’s objections. Regarding the conceivability argument, I want to show that the distinction mobilized by Stoljar between a priori and a priori synthesizable does not help us to elucidate the psychophysical condition for that is a clear disanalogy between (...) the cases presented by Stoljar. Regarding the knowledge argument, I want to show that Stoljar’s argument about experienced Mary undermines the fundamental premise of the knowledge argument and therefore it cannot be mobilized to deflate the phenomenal concept strategy against the knowledge argument. My conclusion will be that Stoljar’s points are ineffective against the phenomenal concept strategy. (shrink)

This paper defends the hypothesis that phenomenal experiences may be very complex information states. This can explain some of our most perplexing anti-physicalist intuitions about phenomenal experience. The approach is to describe some basic facts about information in such a way as to make clear the essential oversight involved, by way illustrating how various intuitive arguments against physicalism (such as Frank Jackson.

This paper presents a new response to the colour similarity argument, an argument that many people take to pose the greatest threat to colour physicalism. The colour similarity argument assumes that if colour physicalism is true, then colour similarities should be scrutable under standard physical descriptions of surface reflectance properties such as their spectral reflectance curves. Given this assumption, our evident failure to find such similarities at the reducing level seemingly proves fatal to colour physicalism. I argue that we should (...) dispense with this assumption, and thus endorse the inscrutability of colour similarity. This strategy is inspired by parallels between the colour similarity argument and the explanatory gap between mind and body made vivid by Jackson’s (1986) knowledge argument, and in particular by type-B physicalist responses to that argument. This inscrutability response is further motivated by cases in chemistry and biochemistry in which analogous scrutability theses fail to hold. Along the way, I present a challenge to standard formulations of the colour similarity argument based on the extreme context sensitivity of the similarity relation. Most presentations of the argument fail to control for such contextual variation, which raises the distinct possibility that the argument equivocates on the similarity relation across its premises. Although ultimately inconclusive, this context challenge forces a significant reformulation of the colour similarity argument, and highlights the need for much greater care in handling claims about colour similarity.

The Knowledge Argument of Frank Jackson has not persuaded physicalists, but their replies have not dispelled the intuition that someone raised in a black and white environment gains genuinely new knowledge when she sees colors for the first time. In what follows, we propose an explanation of this particular kind of knowledge gain that displays it as genuinely new, but orthogonal to both physicalism and phenomenology. We argue that Mary’s case is an instance of a common phenomenon in which something (...) new is learned as the result of exploiting representational resources that were not previously exploited, and that this results in gaining genuinely new information.

At first glance, the properties being omniscient and being worthy of worship might appear to be perfectly co-instantiable. But there are reasons to be worried about this co-instantiability, as it turns out that, depending on our commitments with respect to certain kinds of knowledge and notions of personhood, it might be the case that no being—God included—could instantiate both. In this paper, I lay out and motivate this claim before going on to consider a variety of responses—some more plausible than (...) others—that may be offered by the theist. (shrink)

The philosophy of time travel is a sub-field of metaphysics – the study of what there is and what things are like – that considers questions about the possibility of time travel and what a world in which time travel is possible looks like. These questions range from whether time travel is actually possible, to how time travellers can act in the past or future. This thesis delves into a particularly interesting, yet historically undertreated theme: the abilities of time travellers (...) and relatedly their freedom as well. The abilities and freedom of time travellers has been the source of a lot of recent discussion with some polarising views. The minority (which includes Lewis (1976), but also Ted Sider (2002)) argue for the affirmative – that time travellers are free and have the same (or perhaps more) abilities as non-time travellers. The majority (which includes Kadri Vihvelin (1996), Michael Rea (2005), Stephanie Rennick (2015), Alison Fernandes (2020), amongst others) argue for the negative, that time travellers do not have exactly the same freedoms and abilities as non-time travellers. I think that it is a mistake to be so pessimistic about the abilities and freedom of time travellers. I treat concerns about the freedom of time travellers and concerns about the abilities of time travellers as two sides of the same coin. Therefore, in what follows, I argue for two related conclusions. First, I argue that time travellers have all sorts of abilities. Second, I argue that time travellers are just as free as non-time travellers. In arguing for these conclusions, I first produce a novel analysis of ability which reveals important details about how abilities track inputs rather than outputs. Second, I use this new analysis of ability to present a new compatibilist account of free will. If I am right in arguing positively for the abilities and freedoms of time travellers, then this has large implications for both the current time travel discourse and the general debate surrounding freedom. Significantly, I am arguing against some prominent views about time travel and in suggesting that these views are mistaken, I am presenting new ideas about ability and freedom: specifically, that time travellers have the ability and are free to do impossible things.

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'.

I argue that one central resource for ethical thinking, seriously under-explored in contemporary anglophone philosophy, is moral phenomenology, the exploration of the texture and quality of moral experience. Perhaps a barrier that has prevented people from using this resource is that it’s hard to talk about experience. But such knowledge can be communicated, e.g. by poetry and drama. In having such experiences, either in real life or at second-hand through art, we can gain moral knowledge, rather as Mary the colour (...) scientist can gain knowledge of colours; such knowledge is a real cognitive gain, but it is not knowledge of the propositional kind that philosophers have usually focused on.

I develop the relatively familiar idea of a variety of forms of knowledge —not just propositional knowledge but also knowledge -how and experiential knowledge —and show how this variety can be used to make interesting sense of Plato’s and Aristotle’s philosophy, and in particular their ethics. I then add to this threefold analysis of knowledge a less familiar fourth variety, objectual knowledge, and suggest that this is also interesting and important in the understanding of Plato and Aristotle.
