Unlike identity physicalism, ground physicalism does not achieve the physicalist dream. It faces the T-shirt problem for ground physicalism (Pautz 2014; Schaffer this volume; Rubenstein ms). In the case of insentient nature, it may be able to get by with small handful of very general ground laws to explain the emergence of nonfundamental objects and properties – for example, a few “principle of plenitude”. But I argue that for the case consciousness it will require a separate huge raft of (...) special, anomalous psychophysical ground laws. So it is just as complex and nonuniform as dualism. (shrink)

Phenomenal intentionality is irreducible. Empirical investigation shows it is internally-dependent. So our usual externalist (causal, etc.) theories do not apply here. Internalist views of phenomenal intentionality (e. g. interpretationism) also fail. The resulting primitivist view avoids Papineau's worry that terms for consciousness are highly indeterminate: since conscious properties are extremely natural (despite having unnatural supervenience bases) they are 'reference magnets'.

I develop several new arguments against claims about "cognitive phenomenology" and its alleged role in grounding thought content. My arguments concern "absent cognitive qualia cases", "altered cognitive qualia cases", and "disembodied cognitive qualia cases". However, at the end, I sketch a positive theory of the role of phenomenology in grounding content, drawing on David Lewis's work on intentionality. I suggest that within Lewis's theory the subject's total evidence plays the central role in fixing mental content and ruling out deviant interpretations. (...) However I point out a huge unnoticed problem, the problem of evidence: Lewis really has no theory of sensory content and hence no theory of what fixes evidence. I suggest a way of plugging this hole in Lewis's theory. On the resulting theory, which I call " phenomenal functionalism", there is a sense in which sensory phenomenology is the source of all determinate intentionality. Phenomenal functionalism has similarities to the theories of Chalmers and Schwitzgebel. (shrink)

These are some responses to an early version of Johnston's paper "The Personite Problem" (now published in Nous).

Develops an empirical argument against naive realism-disjunctivism: if naive realists accept "internal dependence", then they cannot explain the evolution of perceptual success. Also presents a puzzle about our knowledge of universals.

I begin with an initial sketch of French and Phillips’ brand of naive realism, which appeals to "ways of perceiving". Then I consider two arguments for it: their own argument concerning illusion, and another argument based on what I have called "internal dependence". Next I turn to criticism. I argue that their “quietism” about "ways of perceiving" is unmotivated; there are several possible positive accounts and it is unclear why French and Phillips reject them. I raise three phenomenological problems for (...) the view. Finally, I raise a problem about sensible qualities. (shrink)

Phenomenal intentionality is a singular form of intentionality. Science shows it is internally-determined. So standard externalist models for reducing intentionality don't apply to it.

This is a reply to Luke Roelof's comments (2017) on my paper "A Dilemma for Russellian Monists about Consciousness" (2015). On both Russellian monism and dualism, experiences are distinct from neural-functional states and they are correlated with some neural-functional states and not others. The only difference between them concerns the status of the extra-logical principles linking experiences with their neural-functional correlates (e. g. increasing S1 firing rates results in increasing pain): Russellian monists hold that they are a priori and necessary, (...) while dualists say that they are a posteriori and contingent. How are we to decide between them? Roelofs suggests that Russellian monism is simpler than dualism. I argue against this. Both face the "T-shirt problem": both require a swarm of extra-logical principles linking brain states with experiences. The Russellian monist might engage in some unbridled speculation: they are somehow derivable from small set of more basic extra-logical principles ("principles of combination"), even if we cannot supply the details. But the dualist can do the same. The only difference is that the dualist will speculate that those more basic principles are contingent rather than necessary a priori. Given our limited evidence, there is no reason (and in particular no simplicity-based reason) to prefer the Russellian monist's speculations to the dualist's parallel speculations. (shrink)

I reply to comments on my book Perception (Routledge 2021) by Umrao Sethi, Jeff Speaks and Brian Cutter. Sethi objects to my representational view of perception on the ground that that having an experience of a color or shape can enable you to know what that color or shape is like only if it is actually present in the experience. Speaks has a very interesting discussion of my puzzle of the laws of appearance for the representational view. And Cutter asks (...) what I have against 'neural sense datum theory'. In my responses, I try to take the discussion forward. At the end, I develop a new argument against reductive physicalist theories of sensible qualities based on a principle I call "qualitative closure". (shrink)

In “Radical Interpretation” (1974), David Lewis asked: by what constraints, and to what extent, do the non-intentional, physical facts about Karl determine the intentional facts about him? There are two popular approaches: the reductive externalist program and the phenomenal intentionality program. I argue against both approaches. Then I sketch an alternative multistage account incorporating ideas from both camps. If we start with Karl's conscious experiences, we can appeal to Lewisian ideas to explain his other intentional states. This account develops the (...) multistage Lewisian approach presented at the end of my earlier "Does Phenomenology Ground Mental Content?" (2013). (shrink)

The Significance Argument (SA) for the irreducibility of consciousness is based on a series of new puzzle-cases that I call multiple candidate cases. In these cases, there is a multiplicity of physical-functional properties or relations that are candidates to be identified with the sensible qualities and our consciousness of them, where those candidates are not significantly different. I will argue that these cases show that reductive materialists cannot accommodate the various ways in which consciousness is significant and must allow massive (...) vagueness in conscious experience. I also will argue that a nonreductive theory of the conscious-of relation can easily provide a very satisfying, unified explanation of the ways in which this relation is significant. (shrink)

In this paper, I do a few things. I develop a (largely) empirical argument against naïve realism (Campbell, Martin, others) and for representationalism. I answer Papineau’s recent paper “Against Representationalism (about Experience)”. And I develop a new puzzle for representationalists.

I address the question of whether phenomenology is "prior to" all intentionality. I also sketch a version of David Lewis's interpretationism in which phenomenal intentionality plays the role of source intentionality.

In this chapter, Pautz raises a puzzle about spatial experience for phenomenal internalists like Ned Block. If an accidental, lifelong brain-in-the-void (BIV) should have all the same experiences as you, it would have an experience as of items having various shapes, and be able to acquire concepts of those shapes, despite being cut off from real things with the shapes. Internalists cannot explain this by saying that BIV is presented with Peacocke-style visual field regions having various shapes, because these (...) would have to be non-physical sense data. They might instead explain this by saying that BIV “phenomenally represents” various shape properties. But since BIV lacks any interesting physical relations to shapes, this would imply that phenomenally representation is an irreducible relation. (shrink)

In the first instance, IIT is formulated as a theory of the physical basis of the 'degree' or ‘level’ or ‘amount’ of consciousness in a system. In addition, integrated information theorists have tried to provide a systematic theory of how physical states determine the specific qualitative contents of episodes of consciousness: for instance, an experience as of a red and round thing rather than a green and square thing. I raise a series of questions about the central explanatory target, the (...) 'degree' or ‘level’ or ‘amount’ of consciousness. I suggest it is not at all clear what scientists and philosophers are talking about when they talk about consciousness as gradable. I also raise some questions about the explanation of qualitative content. (shrink)

In “The Meta-Problem of Consciousness”, David Chalmers briefly raises a problem about how the connection between consciousness and our verbal and other behavior appears “lucky”. I raise a counterexample to Chalmers’s formulation of the problem. Then I develop an alternative formulation. Finally, I consider some responses, including illusionism about consciousness.

Perhaps more than any other philosopher of mind, Ned Block synthesizes philosophical and scientific approaches to the mind; he is unique in moving back and forth across this divide, doing so with creativity and intensity. Over the course of his career, Block has made groundbreaking contributions to our understanding of intelligence, representation, and consciousness. Blockheads! (the title refers to Block's imaginary counterexample to the Turing test—and to the Block-enthusiast contributors) offers eighteen new essays on Block's work along with substantive and (...) wide-ranging replies by Block.

In this paper I will present a puzzle about visual appearance. There are certain necessary constraints on how things can visually appear. The puzzle is about how to explain them. I have no satisfying solution. My main thesis is simply that the puzzle is a puzzle. I will develop the puzzle as it arises for representationalism about experience because it is currently the most popular theory of experience and I think it is along the right lines. However, everyone faces a (...) form of the puzzle, including the naïve realist. In §1 I explain representationalism about experience. In §§2-3 I develop the puzzle and criticize a response due to Ned Block and Jeff Speaks and another response based on a novel form of representationalism (“sensa representationalism”). In §4 I argue that defenders of “perceptual confidence” (Morrison, Munton, my earlier self) face an instance of the puzzle. In §5 I suggest that everyone faces a form of the puzzle. (shrink)

This paper (from 2006) is now defunct. I argue against "realist primitivism". One of my arguments is a kind of "evolutionary debunking argument". Some of the material of this was incorporated into “Can Disjunctivists Explain Our Access to the Sensible World?” and "How Does Color Experience Represent the World?".

Discusses recent work on representationalism, including: the case for a representationalist theory of consciousness, which explains consciousness in terms of content; rivals such as neurobiological type-type identity theory (Papineau, McLaughlin) and naive realism (Allen, Campbell, Brewer); John Campbell and David Papineau's recent objections to representationalism; the problem of the "laws of appearance"; externalist vs internalist versions of representationalism; the relation between representationalism and the mind-body problem.

I criticize some armchair arguments against phenomenal externalism due to Block, Hawthorne, Kriegel, Levine, Shoemaker and others. I conclude by discussing an overlooked armchair argument: the argument from phenomenal localism.

I develop a new argument against Russellian Monism about consciousness.

Many favor representationalism about color experience. To a first approximation, this view holds that experiencing is like believing. In particular, like believing, experiencing is a matter of representing the world to be a certain way. Once you view color experience along these lines, you face a big question: do our color experiences represent the world as it really is? For instance, suppose you see a tomato. Representationalists claim that having an experience with this sensory character is necessarily connected with representing (...) a distinctive quality as pervading a round area out there in external space. Let us call it “sensible redness” to highlight the fact that the representation of this property is necessarily connected with the sensory character of the experience. Is this property, sensible redness, really co-instantiated with roundness out there in the space before you? (shrink)

I begin by describing what I call simple naïve realism. Then I describe relevant empirical results. Next, I develop two new empirical arguments against simple naive realism. Then I briefly look at two new, more complex forms of naïve realism: one due to Keith Allen and the other due to Heather Logue and Ori Beck. I argue that they are not satisfactory retreats for naive realists. The right course is to reject naive realism altogether. My stalking horse is contemporary naive (...) realism but there is a larger, positive lesson: new empirical results support a brain-based theory of sensory consciousness. (shrink)

I develop a problem for the Fregean Reference Shift analysis of that-clause reference. The problem is discussed by Stephen Schiffer in his recent book The Things We Mean (2003). Either the defender of the Fregean Reference Shift analysis must count certain counterintuitive inferences as valid, or else he must reject a plausible Exportation rule. I consider several responses. I find that the best response relies on a Kaplan-inspired analysis of quantified belief reports. But I argue that this response faces some (...) serious problems. (shrink)

In his excellent book *The Metaphysics of Sensory Experience* (2021), David Papineau argues against standard theories of sensory experience: the sense datum view, representationalism, naïve realism, and so on. The only view left standing is his own “qualitative view”. On Papineau’s physicalist version, all experiences are nothing but neural states, and the only features essentially involved in experience are intrinsic neural properties (29-30, 95-97). In my book *Perception* (2021), I developed an argument from spatial experience against this kind of view (...) (also Pautz 2010, 2017). Here I elaborate on that argument in the light of Papineau’s discussion. (shrink)

An overview of the main positions on colour.

In this paper we investigate composition models of incarnation, according to which Christ is a compound of qualitatively and numerically different constituents. We focus on three-part models, according to which Christ is composed of a divine mind, a human mind, and a human body. We consider four possible relational structures that the three components could form. We argue that a ‘hierarchy of natures’ model, in which the human mind and body are united to each other in the normal way, and (...) in which they are jointly related to the divine mind by the relation of co-action, is the most metaphysically plausible model. Finally, we consider the problem of how Christ can be a single person even when his components may be considered persons. We argue that an Aristotelian metaphysics, according to which identity is a matter of function, offers a plausible solution: Christ's components may acquire a radically new identity through being parts of the whole, which enables them to be reidentified as parts, not persons.

This paper elaborates on an argument in my book *Perception*. It has two parts. In the first part, I argue against what I call "basic" naive realism, on the grounds that it fails to accommodate what I call "internal dependence" and it requires an empirically implausible theory of sensible properties. Then I turn Craig French and Ian Phillips’ modified naïve realism as set out in their recent paper "Austerity and Illusion". It accommodates internal dependence. But it may retain the empirically (...) implausible theory of sensible properties. And it faces other empirical problems. Representationalism about experiences avoids those problems and is to be preferred. (shrink)

This is a chapter from my introductory book *Perception* covering the representational view of experience. I use the Ramsey-Lewis method to define the theoretical term "experiential representation". I clarify and discuss various questions for representationalists, for instance, "how rich is the content of experience?" and "is the content of visual experience singular or general?" Finally, I address some objections to representationalism - in particular, that it cannot explain perceptual presence (John Campbell), and that it cannot explain the "laws of appearance" (...) (constraints on how things can appear). (shrink)

Social media has transformed how individuals handle their illnesses. While many patients increasingly use these online platforms to understand embodied information surrounding their conditions, healthcare professionals often frame these practices as negative and do not consider the expertise that patients generate through social media. Through a combination of insights from social epistemology and ignorance studies, this paper problematizes the distinctive understandings of social media between patients and healthcare professionals from a different perspective. A total of four ideas are introduced: (1) (...) healthcare professionals see embodied knowledge that arises from patients’ social media practices as uncomfortable knowledge; (2) healthcare professionals engage in several behaviours to preserve their authority and power in front of embodied knowledge created through these online platforms; (3) failing to consider embodied knowledge can have consequences not only in terms of trust between patients and healthcare professionals but also in connection with epistemological populism and the transition towards patient-centred care; and (4) media and digital health literacy could help healthcare professionals enhance the uses of social media in healthcare. Adopting this framework allows not only to offer valuable insights into how healthcare professionals manage patients’ social media practices, but also opens new avenues to improve healthcare digitisation.

A preview of my book *Perception*. Discusses the relationship between perception and the physical world and the issue of whether reality is as it appears. Useful examples are included throughout the book to illustrate the puzzles of perception, including hallucinations, illusions, the laws of appearance, blindsight, and neuroscientific explanations of our experience of pain, smell and color. The book covers both traditional philosophical arguments and more recent empirical arguments deriving from research in psychophysics and neuroscience. The addition of chapter summaries, (...) suggestions for further reading and a glossary of terms make Perception essential reading for anyone studying the topic in detail, as well as for students of philosophy of mind, philosophy of psychology and metaphysics.

Comments on Jane Friedman "Inquiry and Belief" (for 2015 Ranch Conference). Jane Friedman proposes DBI: One ought not to believe an (complete) answer to a question & at the same time inquire into that question – that’d be irrational. I raise some counterexamples. Then I propose an alternative principle which avoids the counterexamples and which has the further advantage of following from more general platitudes about knowledge. The general point is that even if one believes an answer to a question (...) it is not irrational to inquire as long as epistemic improvement is possible. (This is along the same lines as the principle of *Epistemic Improvement* more recently suggested by Arianna Falbo and Avery Archer.). (shrink)

In previous work (Nanay ed. 2017, Phil Issues 2020), I developed "the problem of the laws of appearance" for representationalism. There are metaphysically necessary constraints appearance and representationalists have difficulty explaining them. Here I develop the problem in a somewhat different way. Then I address the question of whether naive realist might be better placed than representationalists to answer the problem. Perhaps they can derive constraints on appearance from constraints on reality. If so, then the laws of appearance provide a (...) neglected argument for naive realism over representationalism. However, in the end I question whether naive realists really are better placed to answer the problem. (shrink)

Comments on an early version of Johnston's "The Problem with the Content View" (in Berit Brogaard ed. *Does Perception Have Content?*, 2014) delivered at a workshop on perception at NYU in 2010.

This is a chapter from my book Perception (Routledge). I explain the physical state view of sensory experience (Papineau, McLaughlin, others). I criticize an argument against it based on the "transparency observation". Then I develop two alternative arguments against it. The first is a Leibniz's Law argument based on the essentially externally directed character of some experiences. The second concerns "brains in vats". Finally I consider a recent response due to David Papineau, which involves rejecting essential external directedness.

In his superb book, The Metaphysics of Representation, Williams sketches biconditional reductive definitions of representational states in non-representational terms. The central idea is an extremely innovative variety of interpretationism about belief and desire. Williams is inspired by David Lewis but departs significantly from him. I am sympathetic to interpretationism for some basic beliefs and desires. However, I will raise three worries for Williams’s version (§2–4). It neglects the role of conscious experience, it makes beliefs and desire too dependent on "hidden (...) facts", and it commits to the unmotivated and problematic claim that mental content is always explanatorily prior to linguistic content. Then, I will suggest a modified version of interpretationism that avoids these problems (§5). I will conclude with a general question (§6). -/- . (shrink)

One of Jerry Fodor’s many seminal contributions to philosophy of mind was his inner sentence theory of belief and desire. To believe that p is to have a subpersonal inner sentence in one’s “belief-box” that means that p, and to desire that q is to have a subpersonal inner sentence in one’s “desire-box” that means that q. I will distinguish between two accounts of box-inclusion that exhaust the options: liberal and restrictive. I will show that both accounts have the mistaken (...) implication that in certain cases there can be radical but “secret” changes in a subject’s beliefs and desires. I will suggest that the correct moral to draw is that we should instead accept what Eric Schwitzgebel has called a “surface-level” theory of belief and desire. (shrink)

We take it that conscious acquaintance has great epistemic value. I develop a new problem for reductive physicalism concerning the epistemic value of acquaintance. The problem concerns "multiple candidate cases". (This develops a theme of my paper *The Significance Argument for the Irreducibility of Consciousness", Philosophical Perspectives 2017.).

This paper proposes a novel account of the contents of memory. By drawing on insights from the philosophy of perception, I propose a hybrid account of the contents of memory designed to preserve important aspects of representationalist and relationalist views. The hybrid view I propose also contributes to two ongoing debates in philosophy of memory. First, I argue that, in opposition to eternalist views, the hybrid view offers a less metaphysically-charged solution to the co-temporality problem. Second, I show how the (...) hybrid view conceives of the relationship between episodic memory and other forms of episodic thinking. I conclude by considering some disanalogies between perception and memory and by replying to objections. I argue that, despite there being important differences between memory and perception, those differences do not harm my project. (shrink)

1. IntroductionIn this superb book, Williams sets a very ambitious goal for himself: to sketch biconditionals that define representational conditions in non-representational terms (p. xvii). Representation is not a spooky, primitive capacity of the mind; it is built from more basic ingredients. At the centre is his radical interpretation theory of belief and desire, inspired by the work of David Lewis. To a first approximation: Basic radical interpretation theory. The correct assignment of beliefs and desires to an agent is the (...) most rationalizing assignment given her perceptual evidence and dispositions to act. (pp. 16, 97ff)Williams does not give a master argument for this account of belief and desire over rival accounts in which constitutive rationality plays no role. Rather, his main goal is the laudatory one of theory-building. In this respect, his book hearkens back to the decade or so from the early 80s to the early 90s that was the heyday for developing grand theories of representation. In particular, his main aim is to develop the details of the basic radical interpretation theory – something Lewis never fully did. The result is a unique, multi-stage theory of representation that departs importantly from Lewis in many places. (shrink)

Richard Bradley and others endorse Reverse Bayesianism as the way to model awareness growth. I raise a problem for Reverse Bayesianism—at least for the general version that Bradley endorses—and argue that there is no plausible way to restrict the principle that will give us the right results. To get the right results, we need to pay attention to the attitudes that agents have towards propositions of which they are unaware. This raises more general questions about how awareness growth should be (...) modelled. (shrink)

In this commentary on Nuno Venturinha’s Description of Situations, after highlighting what in my view are the most significant and innovative features of his work, I focus on Venturinha’s infallibilist approach to knowledge. This topic allows for a wider discussion concerning the pragmatist aspects of the later Wittgenstein’s philosophy. I discuss this in three steps: first, by describing the general similarity between Wittgenstein and the pragmatists with respect to the emphasis on contexts; second, by focusing on the kind of fallibilism (...) endorsed by the pragmatists and its compatibility with Charles S. Peirce’s concept of the “indubitables,” which I take as a precursor of Wittgenstein’s concept of hinges; and, finally, by advancing the hypothesis that it is possible to find a form of fallibilism in the later Wittgenstein too, notwithstanding his insistence on the impossibility of mistakes. My conclusion is that while Venturinha’s contextualism finds support in the later Wittgenstein’s writings, his infallibilism does not. (shrink)
