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.

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.

In O'Regan & Noë's (O&N's) account for the phenomenal experience of seeing, awareness is equated to what is within the current focus of attention. They find no place for a distinction between phenomenal and access awareness. In doing so, they essentially present a dualistic solution to the mind-brain problem, and ignore that we do have phenomenal experience of what is outside the focus of attention.

Siewert identifies a special kind of conscious experience, phenomenal consciousness, that is the sort of consciousness missing in a variety of cases of blindsight. He then argues that phenomenal consciousness has been neglected by students of consciousness when it should not be. According to Siewert, the neglect is based at least in part on two false assumptions: (i) phenomenal features are not intentional and (ii) phenomenal character is restricted to sensory experience. By identifying an essential tension in Siewert's characterization of phenomenal consciousness, I argue that his case for denying (i) and (ii) is at best incomplete.

It is one thing to have phenomenal states and another thing to think about phenomenal states. Thinking about phenomenal states gives us knowledge that we have them and knowledge of what they are like. But how do we think about phenomenal states? These days, the most popular answer is that we use phenomenal concepts. Phenomenal concepts are presumed to be concepts that represent phenomenal states in a special, intrinsically phenomenal, way. The special nature of phenomenal concepts is said to be important for defending materialism against epistemic arguments for dualism. In this paper I present an account of phenomenal knowledge that does not depend on phenomenal concepts. In fact, I argue that we have no phenomenal concepts. Instead my account appeals to mental pointing, a process that I explain in terms of phenomenal demonstratives. Phenomenal demonstratives are sometimes referred to as concepts in the literature, but I suggest that this is a mistake. I also present a theory of phenomenal demonstratives that equates them with attentional control structures in working memory. In a concluding section I describe how this theory can be used to defuse the knowledge argument for dualism. That is only a subsidiary goal, and my response to the knowledge argument echoes others in the literature. I think the project of developing a substantive, empirically informed theory of phenomenal knowledge has interest independent of debates about mental ontology. That is my central focus. Thinking about phenomenal knowledge can shed light on the relationship between consciousness, attention and memory. This paper has a philosophical agenda and an empirical agenda. Those who reject my philosophical claims about the nonexistence of phenomenal concepts, the conditions..

In an earlier paper (Biggs, 2007) I argue that those attributing mental states sometimes simulate the phenomenal states of those to whom they are making attributions (i.e., targets). In this paper I argue that such phenomenal simulation plays an important role in some third-person mental state attributions. More specifically, I identity three important roles that phenomenal simulation could play in third-person mental state attributions: phenomenal simulation could cause attributions, facilitate attributions, or deepen simulators' understanding of targets. I then argue that phenomenal simulation sometimes deepens simulators' understanding of targets, regardless of whether it causes or facilitates any attributions. Accordingly, I conclude that phenomenal simulation plays an important role some third-person mental state attributions. I close by briefly considering how this conclusion relates to the theory-theory versus simulation-theory debate.

The reduction of the concept of heat to that of molecular kinetic energy is recurrently presented as lending analogical support to the project of reduction of phenomenal concepts to physical concepts. The claimed analogy draws on the way the use of the concept of heat is attached to the experience in first person of a certain sensation. The reduction of this concept seems to prove the possibility to reduce discourse involving phenomenal concepts to a scientific description of neural activity. But is this analogy really justified? We will show that if there is an analogy, far from speaking for a reduction of phenomenal concepts, it rather stresses the necessity to integrate phenomenal reports in the scientific study of experience.

If one were to provide a reductive explanation of phenomenal experience one would explain why there could be a phenomenal experience that identifies itself as an individual that possesses ‘consciousness’. Although not a requirement of reduction, such an explanation would be consistent with our understanding of evolution and, consequently, explain the physical origins and purpose of phenomenal experience. However, this explanation would not explain why a particular conscious individual identifies itself as itself rather than any other individual - Why is ‘my’ consciousness ‘mine’ (materially, or otherwise, irrespective of experiential detail and content) rather than anyone else? What is consciousness outside of phenomenal experience and phenomenal conceptualization? In this paper, I argue that the indeterminacy of quantum mechanics makes it a suitable candidate for exploring the answers to these questions.
