David Lewis—famously—never tasted vegemite. Did he have any knowledge of what it's like to taste vegemite? Most say 'no'; I say 'yes'. I argue that knowledge of what it’s like varies along a spectrum from more exact to more approximate, and that phenomenal concepts vary along a spectrum in how precisely they characterize what it’s like to undergo their target experiences. This degreed picture contrasts with the standard all-or-nothing picture, where phenomenal concepts and phenomenal knowledge lack any such degreed structure. (...) I motivate the degreed picture by appeal to (1) limits in epistemic abilities such as recognition, imagination, and inference, and (2) the semantics of ‘knows what it’s like’ expressions. I argue that approximate phenomenal knowledge cannot be explained merely via determinable or vague phenomenal concepts. I develop a framework for systematizing approximate knowledge of phenomenal character. And I explain how my view challenges some standard assumptions about the acquisition conditions, requirements for mastery, and referential mechanisms of phenomenal concepts. (shrink)

In this paper, I focus on an influential account of phenomenal concepts, the recognitional account, and defend it from some recent challenges. According to this account, phenomenal concepts are recognitional concepts that we use when we recognize experiences as “another one of those.” Michael Tye has argued that this account is viciously circular because the relevant recognitional abilities involve descriptions of the form “another experience of the same type,” which is also a phenomenal concept. Tye argues that we avoid the (...) circularity worry if we explain the reference-fixing of phenomenal concepts in terms of dispositions to re-identify tokens of the same type without appealing to any further phenomenal concepts. However, he argues, this account is incompatible with the intuitive claim that phenomenal concepts seem to involve rich modes of presentation of their referents. Philip Goff and others have similarly argued that a recognitional account of phenomenal concepts would make phenomenal concepts opaque, that is, unable to reveal anything about their referents, which seems problematic. In this paper, I present a new version of the recognitional account that avoids the circularity worry without entailing that phenomenal concepts are opaque. (shrink)

In this paper I develop an argument against a type of Non-Analytic Normative Naturalism. This argument, the Normative Property Dualism Argument, suggests that, if Non-Analytic Normative Naturalists posit that normative properties are identical to natural properties and that such identities are a posteriori, they will be forced to posit that these properties which are both normative and natural have higher-order normative properties of their own.

There is a difference between merely thinking that P and really grasping that P. For example, Jackson's (1982) black-and-white Mary cannot (before leaving her black-and-white room) fully grasp what it means to say that fire engines are red, but she can perfectly well entertain the thought that fire engines are red. The contrast between merely thinking and grasping is especially salient in the context of certain moral decisions. For example, an individual who grasps the plight of starving children thanks to (...) evocative images seems much more likely to donate for the children's benefit than someone who is merely told about their plight. This paper offers a phenomenal account of grasping according to which grasping a content (whether a proposition or concept) consists in one's thoughts about the content being constituted by phenomenal experiences of constituents of the content. This account improves on earlier phenomenal accounts of grasping (Bourget 2017a, 2018) by allowing for partial grasping and generalizing to concepts. The paper also addresses objections to phenomenal accounts of grasping, including the objection that recent developments in AI technology show that consciousness is irrelevant to grasping and understanding.

Many contemporary physicalists concede to dualists that conscious subjects have distinctive “phenomenal concepts” of the phenomenal qualities of their experiences. Indeed, they contend that idiosyncratic characteristics of these concepts facilitate responses to influential anti-physicalist arguments. Like some some other critics of this approach, James Tartaglia maintains that phenomenal concepts express contents that conflict with physicalism, but as a physicalist, the moral he distinctively draws from this is that phenomenal concepts misrepresent. He contends further that the contemporary physicalists’ account cannot accommodate (...) this feature, and that in consequence, physicalists should abandon phenomenal concepts and return to the identity theory championed by Place and Smart in the 1950s. I respond to Tartaglia by identifying lacunae in his interpretation of contemporary physicalism and arguing that phenomenal concepts as conceived by the contemporary physicalists do not express content...

The paper addresses a prima facie tension between two popular views about concepts. The first is the doctrine that some concepts are constitutively perceptual/experiential, so that they can be possessed only by suitably experienced subjects. This is a classic empiricist theme, but its most conspicuous recent appearance is in literature on phenomenal concepts. The second view is anti-individualism: here, the view that concept possession depends not only on a thinker’s internal states and relations to the concepts’ referents, but also on (...) certain of her relations to sociolinguistic peers. In recent works, Derek Ball and Michael Tye have in effect argued that the doctrines are incompatible, and their conclusion is that no concepts depend on experience. In reply, Bénédicte Veillet endorses those authors’ incompatibilism, but argues that it is anti-individualism that we should reject. I develop an approach to reconciliation that is more promising than any considered by these theorists. Against Veillet, I defend a version of anti-individualism about phenomenal concepts, but against Ball and Tye, I argue that they can be possessed only by suitably experienced thinkers. (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)

Many epistemological problems can be solved by the objective Bayesian view that there are rationality constraints on priors, that is, inductive probabilities. But attempts to work out these constraints have run into such serious problems that many have rejected objective Bayesianism altogether. I argue that the epistemologist should borrow the metaphysician’s concept of naturalness and assign higher priors to more natural hypotheses.

An attractive picture of the world is that some features are metaphysically fundamental and others are derivative, with the derivative features grounded in the fundamental features. But how do we have justified beliefs about which features are fundamental? What is the epistemology of fundamentality? I sketch a response in this paper. The guiding idea is that the same properties cause the same experiences. I argue that a probabilistic connection between epistemic fundamentality and metaphysical fundamentality is sufficient for justified beliefs about (...) the metaphysically fundamental. (shrink)

Russellian physicalism is becoming increasingly popular because it promises to deliver what everybody wants, realism and physicalism about consciousness. But Russellian physicalists are not the first to swear on “the promise”, standard Type-B physicalism is a less fanciful view that also claims to give everything and take nothing. In this paper, I argue that our hopes should not be placed on Russellian physicalism because, unlike Type-B physicalism, it cannot explain how phenomenal concepts can reveal the nature of phenomenal properties without (...) weakening its physicalist credentials. The revelation challenge shows that Russellian physicalism is either committed to an anti-realist and self-defeating view of phenomenal concepts or it is physically unacceptable. (shrink)

The question of how properties are individuated is extremely important. Consider the following proposals. To be in pain is to be in a certain neurological state. To be red is to appear red to normal observers in standard conditions. To be obligatory is to maximize the good. Each makes a claim of property identity. Each is a substantive metaphysical thesis of wide interest. None can be studied with due scrutiny in the absence of a general account of property identity. Here, (...) I will survey existing accounts and suggest a new account in terms of grounding that has some advantages over the other candidates. (shrink)

In this paper, I argue for a version of panpsychist idealism on first-person experiential grounds. As things always appear in my field of consciousness, there is prima facie empirical support for idealism. Furthermore, by assuming that all things correspond to a conscious perspective or perspectives (i.e., panpsychism), realism about the world is arguably safeguarded without the need to appeal to God (as per Berkeley’s idealism). Panpsychist idealism also has a phenomenological advantage over traditional panpsychist views as it does not commit (...) perceptual experience to massive error by denying that perceived colours are properties of things. Finally, I argue that the subject combination problem for panpsychism has been motivated by the problematic assumption that consciousness is in things. Thinking about subject combination from the first-person perspective is fruitful for reframing the subject combination problem and for seeing how subjects could potentially combine for the idealist.

Few these days dispute that the knowledge argument demonstrates an epistemic gap between the physical facts and the facts about experience. It is much more contentious whether that epistemic gap can be used to demonstrate a metaphysical gap of a kind that is inconsistent with physicalism. In this paper I will explore two attempts to block the inference from an epistemic gap to a metaphysical gap – the first from the phenomenal concept strategy, the second from Russellian monism – and (...) suggest how the proponent of the knowledge argument might respond to each of these challenges. In doing so, I will draw on recent discussions of grounding and essence in the metaphysics literature. (shrink)

A review of recent work on physicalism, focusing on what it means to say nothing exists over and above the physical, how "the physical" should be defined, and the causal argument for physicalism.

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)

In his Consciousness and Fundamental Reality (2017) Philip Goff defends his anti-physicalist argument against what he calls the "Dual Carving" objection—the idea that two representations of the very same fact could both be conceptually independent and "transparent," that is, revealing of the essences of the entities in question. His defense invokes a thesis he calls "Minimal Rationalism." I explore exactly how Minimal Rationalism is supposed to turn aside the objection and argue that the formulation of Minimal Rationalism on offer is (...) ambiguous between stronger and weaker readings. Goff needs the stronger reading to use it in defense of his argument, but only the weaker reading is warranted by the considerations he brings to bear in favor of his rationalism. His minimal rationalism is, in sum, insufficiently minimal. The upshot is not only that Goff is deprived of a way of turning back an important objection to his case against physicalism; we also gain a better sense of what kind of rationalist thesis is properly invoked in metaphysics.

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

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

As a first pass, physicalism is the doctrine that there is nothing over and above the physical. Much recent philosophical work has been devoted to spelling out what this means in more rigorous terms and to assessing the case for the view. What follows is a survey of such work. I begin by looking at competing accounts of what is meant by nothing over and above and then turn to how the physical should be understood. Once we are clear on (...) the options for formulating the physicalist thesis, we will look at the leading argument for the view. Along the way, I will suggest avenues for further exploration.

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

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

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

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

According to a widely held physicalist view, consciousness is identical with some physical or functional phenomenon just as liquidity is identical with loose molecular connection. To many of us, this claim about consciousness seems more problematic than the claim about liquidity. To many—including many physicalists—the identification of consciousness with some physical phenomenon even seems “absurd” or “crazy”. A full defence of physicalism should explain why the allegedly correct hypothesis comes across this way. If physicalism is true and we have reason (...) to accept it, why does it seem “absurd”? One possibility is that this is fully explained by the fact that we have an erroneous understanding of consciousness or its physical basis. This explanation is embraced by few if any physicalists. It is rejected by many, including proponents of the “phenomenal concept strategy”, which lately has become the dominant strategy for defending physicalism. But the “error explanation” is clearly the most plausible explanation that is available to physicalists. So this paper argues. (shrink)

This paper is a critique of the radical enactivism of Daniel Hutto, Erik Myin, and their collaborators, insofar as their approach pertains to the hard problem of consciousness. I argue that their valiant attempt to discard the hard problem is ultimately unsuccessful. More specifically, I argue that the hard problem of consciousness is best construed as a transcendental challenge and that no phenomeno-physical identity theory, and no “logic of identity”, successfully eliminate this challenge. Finally, I argue that the theoretical stance (...) adopted by Hutto, Myin, and their colleagues is inherently unstable in that it inadvertently blends strong deflationary currents with an implicit commitment to substantive metaphysical revisionism. Since deflationism and revisionism are discordant partners their forced union results in a position whose overall coherence is compromised. Such disequilibrium, I believe, is a general characteristic of radical enactivist approaches to consciousness, of which the position discussed on the present occasion is one prominent representative.

Materialism/physicalism that generally dominates in the contemporary analytic philosophy is challenged by fairly powerful anti-materialist arguments, notably the zombie argument (most influentially defended by David Chalmers) and the knowledge argument (the most widely discussed version of which was advanced and defended by Frank Jackson). These arguments highlight the explanatory gap from the physical (which, if materialism is true, should constitute everything that exists, including consciousness) to phenomenal mental states, the principal impossibility to explain the latter by the former, and from (...) this conclude that phenomenal consciousness is not physical, and so materialism is false. Materialist philosophers attempt to neutralize these arguments in several ways, the most influential of which is the strategy of phenomenal concepts. This article analyzes the main points of this debate with a focus on the knowledge argument, examines and responds to the main objections to the knowledge argument — that it should be mistaken because the alternative is epiphenomenalism, which is unacceptable; that no new knowledge but only new capacities and/or acquaintance are involved; that the knowledge is the same but in different forms; that the knowledge argument affects only type physicalism but not token physicalism. The case is made that psychophysical identities assumed by a posteriori physicalism are unexplainable in principle, and the postulation of brute unexplainable psychophysical identities glossed over by the strategy of phenomenal concepts amounts to dogmatic commitment (motivated by scientism) to a view despite its apparent falsity and its unintelligibility (the impossibility to explain how it can be true), made less unpalatable by offering an ad hoc theory about the mindbrain arrangement that makes us unable to see how the view can be true. As opposed to this, the position of the supporters of the knowledge argument and the zombie argument can be seen as guided by the principle of rational trust in obviousness and our capacities of judgement. (shrink)

Hidden nature physicalists hold that an experiential quality and its hidden nature are the same property – even though they agree that our experiences are of experiential qualities but are not, in the same sense, experiences of their hidden natures. This paper argues that physicalists must be committed to ultimately giving accounts that involve no non-extensional relations, and that this commitment leads to an inability to explain how our experiences could be of experiential qualities, but not of their hidden natures.

Materialism is the view according to which a zombie world is metaphysically impossible. Assuming that zombies are conceivable in the sense that we cannot rule out a priori that our world is a zombie world, materialists must hold that a zombie world is metaphysically impossible despite being conceivable. There are no good reasons to think that this view (type-B materialism) is false, since there are no good reasons to think that the corresponding phenomenal and physical/functional concepts cannot be distinct concepts (...) of the same thing. Nonetheless, we cannot understand how type-B materialism can be true. We cannot understand this, because we cannot in principle explain how a zombie world could be impossible despite being conceivable. (shrink)

It is widely agreed among contemporary philosophers of mind that science leaves us with an ‘explanatory gap’—that even after we know everything that science can tell us about the conscious mind and the brain, their relationship still remains mysterious. I argue that this agreed view is quite mistaken. The feeling of a ‘explanatory gap’ arises only because we cannot stop ourselves thinking about the mind–brain relation in a dualist way.

I shall argue in this article that there are certain objectual and methodological boundaries imposed by the nature of physics that all formulations of physicalism based on physical theories should respect. Therefore, empirical physicalism – i.e., the sort of physicalism that is eager to accept all the entities included in some future, ideal and complete physical theory and all entities dependent on them (see Jeffrey Poland and Janice Dowell) – is already committed to the exclusion of certain sorts of entities (...) from its ontological inventory and it is far less tolerant than one might expect. After having presented my argument, I shall describe four plausible boundaries to what can be studied by physics. The boundaries will contribute to constructing a new version of physicalism, i.e., physics physicalism, whose acceptance is entailed by the acceptance of empirical physicalism. Finally, I shall briefly deal with three objections against my strategy and I shall evaluate the consequences of the acceptance of my conclusions for both physicalists and non-physicalists. (shrink)

Is a subject who undergoes an experience necessarily aware of undergoing the experience? According to the view here developed, a positive answer to this question should be accepted if ‘awareness’ is understood in a specific way, - in the sense of what will be called ‘primitive awareness’. Primitive awareness of being experientially presented with something involves, furthermore, being pre-reflectively aware of oneself as an experiencing subject. An argument is developed for the claims that pre-reflective self-awareness is the basis of our (...) understanding of what it is to be an experiencing subject and that that understanding reveals what being an experiencing subject consists in and what it is for experiences to belong to one single experiencer. Claim is used in an argument in favor of the so-called simple view with respect to synchronic and diachronic unity of consciousness. (shrink)

According to the experience property framework qualia are properties of experiences the subject undergoing the experience is aware of. A phenomenological argument against this framework is developed and a few mistakes invited by the framework are described. An alternative to the framework, the framework of experiential properties is presented and defended as preferable. It is argued that the choice between these two frameworks makes a substantial difference for theoretical purposes.

I aim to show that, contrary to standard deflationary or eliminativist theories of the self, we can argue from the phenomenology of pre-reflective self-awareness for the thesis that subjects of experience are substances. The phenomenological datum of subjectivity points to a specific metaphysical structure of our experience, that is, towards the substance view rather than the bundle or the minimal self view. Drawing on modern philosophical accounts of pre-reflective self-awareness, mineness and (self-) acquaintance, I will argue that a subject is (...) aware of being the one individual who has many experiences and that it is revealed to the subject that it is the bearer of experiences and their unifier. The subject is present in pre-reflective awareness and known as the subject of experiences, and even this minimal self-awareness gives us reason to favour the substance view. Thus, one can demonstrate how the debates on the phenomenology of pre-reflective self-awareness and the metaphysics of selfhood intersect. (shrink)

We distinguish between different problems of “aboutness”: the “hard” problem of explaining the everyday phenomenon of intentionality and three less challenging “easy” sets of problems concerning the posits of folk psychology, the notions of representation invoked in the mind‐brain sciences, and the intensionality (with an “s”) of mental language. The problem of intentionality is especially hard in that, as is the case with the hard problem of phenomenal consciousness, there is no clear path to a solution using current methods. We (...) argue that naturalistic theories of mental representation do not address the hard problem—either they are only intended to address the easy problems, or the claims they make help address the problem of intentionality only under undefended and prima facie implausible assumptions to the effect that the hard problem reduces to some combination of the easy problems. We offer a positive account of what would be required to properly face up to the problem of intentionality. (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)

We more or less understand how composition works in the case of objects. We cement bricks together to build a wall. We stir together red paint and yellow paint to get orange paint. In both cases, one way or another, A = B + C. This paper examines composition in the case of concrete natural properties. It explains why property composition is so much less straightforward than object composition. Then it distinguishes strictly basic properties , compositely basic properties , and (...) fully non-basic properties . It shows how strictly basic properties compose, or result in, compositely basic and fully non-basic properties, which differ from, yet depend for their natures on, the strictly basic properties they result from. It explains the characteristics and differences of these types of properties. It notes that the existence of compositely basic and non-basic properties grounds an argument for the genuine existence of co.. (shrink)

ABSTRACTType B, or a posteriori, physicalism is the view that phenomenal-physical identity statements can be necessarily true, even though they cannot be known a priori—and that the key to understanding their status is to understand the special features of our phenomenal concepts, those concepts of our experiential states acquired through introspection. This view was once regarded as a promising response to anti-physicalist arguments that maintain that an epistemic gap between phenomenal and physical concepts entails that phenomenal and physical properties are (...) distinct. More recently, however, many physicalists have lost confidence in the view, and have proposed less promising defences of physicalism—or have become outright sceptical about its prospects. I argue here that these physicalists have underestimated the resources of Type B physicalism and are thereby retreating too quickly—or fighting battles that have already been won. (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)

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. (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)

How could perceptual experiences reveal matters of essentiality? Answering this question is crucial for vindicating a thesis about the epistemic import of experience, commonly known as Revelation. The thesis comes in a weak and a strong version. Only on the strong one could it make up an authoritative piece of common sense. But this version also seems to demand too much of our experiences, namely that they can reveal essentiality. However, the impression that our experiences are not suited for this (...) turns out to be due to a non-mandatory assumption about how the revelation of essentiality would work. (shrink)

According to conceptual reductive accounts, if properties of one domain can be conceptually reduced to properties of another domain, then the former properties are ontologically reduced to the latter properties. I will argue that conceptual reductive accounts face problems: either they do not recognise that many higher-level properties are correlated with multiple physical properties, or they do not clarify how we can discover new truthmakers of sentences about a higher-level property. Still, there is another way to motivate ontological reduction, the (...) truthmaker reductive explanations (TRE). TRE can be given by using resources from John Heil’s truthmaker theory and the a priori entailment view or the a posteriori entailment view. I will argue that we can give these truthmaker reductive explanations if there are various less-than-perfectly similar physical properties that can be the truthmakers of sentences about higher-level properties and the physical similarity between them can explain why an irreducible higher-level property is not needed. (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)

Zombies are bodies without minds: creatures that are physically identical to actual human beings, but which have no conscious experience. Much of the consciousness literature focuses on considering how threatening philosophical reflection on such creatures is to physicalism. There is not much attention given to the converse possibility, the possibility of minds without bodies, that is, creatures who are conscious but whose nature is exhausted by their being conscious. We can call such a ‘purely conscious’ creature a ghost.

In the recent metaphysics literature, a number of philosophers have independently endeavoured to marry sparse ontology to abundant truth. The aim is to keep ontological commitments minimal, whilst allowing true sentences to quantify over a vastly greater range of entities than those which they are ontologically committed to. For example, an ontological commitment only to concrete, microscopic simples might be conjoined with a commitment to truths such as ‘There are twenty people working in this building’ and ‘There are prime numbers (...) greater than 5.’ I argue that a significant challenge to this project comes from the philosophy of mind. As Theodore Sider has pointed out, anti-physicalism is consistent with a sparse ontology. However, I will try to show that the premises of the standard anti-physicalist arguments can be used to form an argument to the conclusion that sentences which quantify over subjects of experience ontologically commit us to subjects of experience. Truths about consciousness cannot be bought more cheaply than their superficial grammar suggests. (shrink)

Introspection presents our phenomenal states in a manner otherwise than physical. This observation is often thought to amount to an argument against physicalism: if introspection presents phenomenal states as they essentially are, then phenomenal states cannot be physical states, for we are not introspectively aware of phenomenal states as physical states. In this article, I examine whether this argument threatens a posteriori physicalism. I argue that as along as proponents of a posteriori physicalism maintain that phenomenal concepts present the nature (...) of their referents in a partial and incomplete manner, a posteriori physicalism is safe.
