In his recent work, Dretske offers a new account of what it is for a mental state, in particular, a sensory experience, to be conscious. According to Dretske’sproposal, subject S’s experience of object O is conscious if and only if it makes S aware of O. This proposal is argued to be open to only two serious interpretations. The first takes it to mean that S’s experience of O is conscious if and only if it constitutes S’s awareness of O, whereas the second takes it to mean that S’s experience of O is conscious if and only if it causes S’s awareness of O. It is argued that neither is a plausible way to understand the nature of state consciousness, because the constitutive interpretation implausibly denies the existence of unconscious veridical experiences, whereas the causal interpretation implausibly casts S’s veridical experience of O, rather than O or a certain external event involving O, as the relevant cause of S’s awareness of O.

Two aspects of consciousness are first considered: consciousness as awareness (phenomenological meaning) and consciousness as strategic control (functional meaning). As to awareness, three types can be distinguished: first, awareness as the phenomenal experiences of objects and events; second, awareness as meta-awareness, i.e., the awareness of mental life itself; third, awareness as self-awareness, i.e., the awareness of being oneself. While phenomenal experience and self-awareness are usually present during dreaming (even if many modifications are possible), meta-awareness is usually absent (apart from some particular experiences of self-reflectiveness) with the major exception of lucid dreaming. Consciousness as strategic control may also be present in dreams. The functioning of consciousness is then analyzed, following a cognitive model of dream production. In such a model, the dream is supposed to be the product of the interaction of three components: (a) the bottom-up activation of mnemonic elements coming from LTM systems, (b) interpretative and elaborative top-down processes, and (c) monitoring of phenomenal experience. A feedback circulation is activated among the components, where the top-down interpretative organization and the conscious monitoring of the oneiric scene elicitates other mnemonic contents, according to the requirements of the dream plot. This dream productive activity is submitted to unconscious and conscious processes.

In his recent book ‘Kant and the Mind’ Andrew Brook makes a distinction between two types of selfawareness. The first type, which he calls empirical self-awareness, is an awareness of particular psychological states such as perceptions, memories, desires, bodily sensations etc. One attains this type of self-awareness simply by having particular experiences and being aware of them. To be in possession of empirical self-awareness is, in short, simply to be conscious of one’s occurrent experience. The second type of self-awareness he calls apperceptive self-awareness. This type of self-awareness entails an awareness of oneself as the subject of experience. For this type of self-awareness to obtain, it would not be enough merely to be conscious of, say, an occurrent perception of a chair, one would also have to be aware that it was oneself who was perceiving the chair. And as Brook adds, when I am self-aware in this way, I am not only aware of being the subject of a single experience, but also aware of myself as the common subject of other psychological states (Brook, 1994: 55-57). I find Brook’s distinction illuminating, but it raises a question which I would like to pursue in this paper. When we speak of self-awareness, do we then necessarily also speak of a self, is there so to speak always a self involved in self-awareness, or is it rather the case, as Brook’s notion of empirical selfawareness might suggest, that there are types of self-awareness which are ‘selfless’, or to use two other related terms ‘subjectless’ or ‘non-egological’? Is self-awareness always to be understood as an awareness of a self, or can it be understood simply as the awareness which a specific experience has of itself? Ultimately, I believe an answer to these questions are important, both when it comes to an understanding of what exactly self-awareness amounts to, and also when it comes to a proper understanding of what a self is..

Two claims have been prominent in recent discussions of self-consciousness. One is that first-person reference or first-person thinking is irreducible (the Irreducibility Thesis), and the other is that an awareness of self accompanies all conscious states, at least those through which one refers to something. The latter--here termed the Ubiquity Thesis--has long been associated with philosophers like Fichte, Brentano, and Sartre, though each articulated his own version of the claim. More recently, variants have been defended by Dieter Henrich (1970) and Manfred Frank (1991, 1995a, 1995b). In Frank's words.

I question whether it is completely accurate to think of the philosophical meaning of consciousness as being switched-on or switched-off. It may be that, once consciousness is switched-on, it is then found in degrees in animals we deem conscious. In which case, consciousness is more like a switched-on rheostat, rather than a simple on-off switch. Christian de Quincey (2006) gives a list of what would be considered the marks of consciousness, including 'experience, subjectivity, sentience, feeling, or mentality of any kind'. He also seems to conflate awareness with experience when speaking about the light of consciousness being on. In keeping with de Quincey's desire to get clear about the meaning of consciousness, I will put forward an idea of consciousness as the experience of oneself as a being subject to past, present, and future events, and contrast this idea with a state of awareness. De Quincey claims that 'any entity that is a subject -- that feels its own being -- possesses consciousness'. I want to add to this meaning of consciousness by noting the subject's sense of temporality, so as to further qualify the meaning of consciousness and show how awareness is distinct from consciousness.

To adopt a first-person perspective on consciousness is typically understood as a matter of inwardly engaging one's awareness in such a way as to make one's conscious states and their properties into objects of awareness. When awareness is thus inwardly engaged, experience functions as both act and object of awareness. As objects of awareness, an experience-token and its various properties are items of which a subject is aware. As an act of awareness, an experience-token is that in virtue of which items - in this case, other experience-tokens and their properties - can appear, to a subject, as objects of awareness. The precise nature of the relation between experience functioning as act and as object is a matter of dispute. However, two broad possibilities can be distinguished: (1) as acts of awareness, experiences reveal other experiences to subjects by way of a form of direct, unmediated, acquaintance, (2) as acts of awareness experiences reveal other experiences to subjects by way of modes of presentation of those experiences. I shall argue against (1). Possibility (2), I shall argue, entails a form of representationalism about experiences: experiences are defined by their representational role. However, (2) also yields a crucial but largely neglected consequence of representationalism: necessarily, in any given experience, there is an aspect of this experience that must be understood in terms of its representational role but cannot be understood in terms of its representational content. I shall call this the ineliminable intentional core of the experience. The ineliminable intentional core of the experience is, necessarily, not an object of inwardly engaged awareness. This entails a significant revision in the way we think about the concept of the first-person perspective, and of what it is to study consciousness from the inside.

An evolutionary point of view is proposed to make more appropriate distinctions between experience, awareness and consciousness. Experience can be defined as a characteristic linked closely to specific pattern matching, a characteristic already apparent at the molecular level at least. Awareness can be regarded as the special experience of one or more central, final modules in the animal neuronal brain. Awareness is what experience is to animals.Finally, consciousness could be defined as reflexive awareness. The ability for reflexive awareness is distinctly different from animal and human awareness and depends upon the availability of a separate frame of reference, as provided by symbolic language. As such, words have made reflexive awareness.

One of the more refractory problems in contemporary discussions of consciousness is the problem of determining what a mental state's being conscious consists in. This paper defends the thesis that a mental state is conscious if and only if it has a certain reflexive character, i.e., if and only if it has a structure that includes an awareness of itself. Since this thesis finds one of its clearest expressions in the work of Brentano, it is his treatment of the thesis on which I initially focus, though I subsequently bring in Sartre where he addresses himself to an important point not considered by Brentano. As part of this investigation, the paper also, more specifically, aims to exhibit as perspicuously as possible the relationship between self-awareness and the phenomenal, or 'what-it- is-like', dimension of conscious experience. I attempt to show, in particular, that the phenomenal character of at least perceptual consciousness can be fully explained in terms of self-awareness, i.e., in terms of a low-level or 'implicit' self-awareness that is built into every conscious perceptual state.

Representationalism is a thesis about the phenomenal character of experiences, about their immediate subjective ‘feel’.1 At a minimum, the thesis is one of supervenience: necessarily, experiences that are alike in their representational contents are alike in their phenomenal character. So understood, the thesis is silent on the nature of phenomenal character. Strong or pure representationalism goes further. It aims to tell us what phenomenal character is. According to the theory developed in Tye 1995, phenomenal character is one and the same as representational content that meets certain further conditions. One very important motivation for this theory is the so-called ? transparency of experience.? The purpose of this paper is to elucidate the appeal to transparency more carefully than has been done hithertofore, to make some remarks about the introspective awareness of experience in light of this appeal, and to consider one problem case for transparency at some length, that of blurry vision. Along the way, I shall also address some of the remarks Stephen Leeds makes in his essay on transparency.

In this paper, a theoretical account of the functional role of consciousness in the cognitive system of normal subjects is developed. The account is based upon an approach to consciousness that is drawn from the phenomenological tradition. On this approach, consciousness is essentially peripheral self-awareness, in a sense to be duly explained. It will be argued that the functional role of consciousness, so construed, is to provide the subject with just enough information about her ongoing experience to make it possible for her to easily obtain as much information as she may need. The argument for this account of consciousness' functional role will proceed in three main stages. First, the phenomenological approach to consciousness as peripheral self-awareness will be expounded and endorsed. Second, an account of the functional role of peripheral perceptual awareness will be offered. Finally, the account of the functional role of peripheral self-awareness will be obtained by straightforward extension from the functional role of peripheral perceptual awareness.
