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.

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)

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.

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” face an instance of the puzzle. In §5 I suggest that everyone faces a form of the puzzle. (shrink)

I argue for three claims. First, there is a strong argument for identity physicalism (Lewis, Sider, Dorr) over dualism. It does achieve the physicalist dream of a maximally simple and uniform view of reality. However, there are also strong arguments against identity physicalism concerning the special nature of conscious experiences. Second, although nonidentity "ground" physicalism (Campbell, Johnston, Schaffer) is a possible fallback position, there is no reason to prefer to property dualism. It provides an equally complex and unattractive picture of (...) nature. Third, assuming identity physicalism fails, we also should not much care about which of these options is right. In fact, it becomes difficult to understand the difference. The upshot is that, when it comes to the metaphysics of consciousness, the “big divide” is between identity physicalism (Lewis, Sider, Dorr) and all the rest. This is where the debate should focus.

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 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)

I raise a series of basic question about what the integrated information theory of consciousness comes to.

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. 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)

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'.

It's not clear what integrated information theorists (Koch, Tononi) are saying. And their view lacks the resources to explain even very rudimentary facts about experiences.

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.

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.

This is a chapter from my forthcoming 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 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)

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.

Philosophical theories of color divide over two issues. First, there is the issue of Reductionism versus Primitivism. _Reductionism_ holds that colors are identical with physical properties, dispositional properties, or other properties specifiable in non-chromatic terms.

I raise some objections to the theory presented in *Outside Color*.

Does it matter whether we perceptually represent tomato-hood?
