How can phenomenal consciousness exist as an integral part of a physical universe? How can the technicolour phenomenology of our inner lives be created out of the complex neural activities of our brains? Many have despaired of finding answers to these questions; and many have claimed that human consciousness is inherently mysterious. Peter Carruthers argues, on the contrary, that the subjective feel of our experience is fully explicable in naturalistic (scientifically acceptable) terms. Drawing on a variety of interdisciplinary resources, he develops and defends a novel account in terms of higher-order thought. He shows that this can explain away some of the more extravagant claims made about phenomenal consciousness, while substantively explaining the key subjectivity of our experience. Written with characteristic clarity and directness, and surveying a wide range of extant theories, this book is essential reading for all those within philosophy and psychology interested in the problem of consciousness.

Following a short introduction, this chapter begins by contrasting two different forms of higher-order perception (HOP) theory of phenomenal consciousness - inner sense theory versus a dispositionalist kind of higher-order thought (HOT) theory - and by giving a brief statement of the superiority of the latter. Thereafter the chapter considers arguments in support of HOP theories in general. It develops two parallel objections against both first-order representationalist (FOR) theories and actualist forms of HOT theory. First, neither can give an adequate account of the distinctive features of our recognitional concepts of experience. And second, neither can explain why there are some states of the relevant kinds that are phenomenal and some that aren.

I have very little disagreement with Carruthers' article, for our views are very similar. I think he is terminologically a bit hard on Michael Tye. I think that in invoking Swampman he is in danger of conflating teleological theories of representation with etiological theories of teleology. In response to his criticism of my own higher-order experience (HOE) view, I argue that there is good reason to believe that we human beings sport as great a degree of computational complexity as is needed for HOEs. If other animals do not exhibit a comparable degree, we should deny that they have "phenomenal-consciousness" in the strong sense of that term.

Higher-order theories of consciousness, such as those of Armstrong, Rosenthal and Lycan, typically distinguish sharply between consciousness and phenomenal character, or qualia. The higher-order states posited by these theories are intended only as explanations of consciousness, and not of qualia. In this paper I argue that the positing of higher-order perceptions may help to explain qualia. If we are realists about qualia, conceived as those intrinsic properties of our experience of which we are introspectibly aware, then higher-order perception might have an explanatory role as the means by which we are aware of these properties. This would also allow us to treat qualia as the inner appearances resulting from inner perceptions, and therefore to treat them as intentional objects.

be realized. Whatever gets access to phenomenal awareness (to consciousness and P-consciousness are almost always present or P-consciousness as described by Block) is represented within this absent together.

In this paper we present a two-stage argument against Peter Carruthers' theory of phenomenal consciousness. The first stage shows that Carruthers' main argument against first-order representational theories of phenomenal consciousness applies with equal force against his own theory. The second stage shows that if Carruthers can escape his own argument against first-order theories, it will come at the cost of wedding his theory to certain unwelcome implausibilities. discusses Carruthers' argument against first-order representationalism. presents Carruthers' theory of consciousness. presents our argument against Carruthers' theory. sums up.

I want to present a puzzle for the higher-order thought theory as presented by David Rosenthal in his Consciousness and Mind (Rosenthal 2005; all quotes will be to this book). I do not want to consider whether Rosenthal’s view is correct or not or the advantages that it may have over other versions of higher-order theories. Rather what I want to do is grant all of the assumptions of Rosenthal’s version of the theory and then argue that it commits us to a rather startling result. In short form; if we have really explained phenomenal consciousness, or phenomenology –by which I mean the distinctive property of there being something that it is like for the creature that has the conscious experience—, then it should turn out that conscious thoughts have a phenomenology as well. Put slightly differently the puzzle is this. Once one comes to understand and accept Rosenthal’s account of how and why phenomenal consciousness is non-mysterious it then becomes strange that thoughts do not get the same treatment.

In this paper I consider recent discussions within the representationalist theories of phenomenal consciousness, in particular, the discussions between first order representationalism (FOR) and higher order representationalism (HOR). I aim to show that either there is only a terminological dispute between them or, if the discussion is not simply terminological, then HOR is based on a misunderstanding of the phenomena that a theory of phenomenal consciousness should explain. First, I argue that we can defend first order representationalism from Carruthers' attacks and ignore higher order thoughts in our account of phenomenal consciousness. Then I offer a diagnostic of Carruthers' misunderstanding. In the last section I consider further reasons to include mindreading abilities in an explanation of phenomenal consciousness.

Relying on a range of now-familiar thought-experiments, it has seemed to many philosophers that phenomenal consciousness is beyond the scope of reductive explanation. (Phenomenal consciousness is a form of state-consciousness, which contrasts with creature-consciousness, or perceptual-consciousness. The different forms of state-consciousness include various kinds of access-consciousness, both first-order and higher-order--see Rosenthal, 1986; Block, 1995; Lycan, 1996; Carruthers, 2000. Phenomenal consciousness is the property that mental states have when it is like something to possess them, or when they have subjectively-accessible feels; or as some would say, when they have qualia (see fn.1 below).) Others have thought that we can undermine the credibility of those thought-experiments by allowing that we possess purely recognitional concepts for the properties of our conscious mental states. This paper is concerned to explain, and then to meet, the challenge of showing how purely recognitional concepts are possible if there are no such things as qualia--in the strong sense of intrinsic (non-relational, non-intentional) properties of experience. It argues that an appeal to higher-order experiences is necessary to meet this challenge, and then deploys a novel form of higher-order thought theory to explain how such experiences are generated.
