Abstract: It is argued that it is important for cognitive scientists to understand both the precise nature of RTM, and the challenges to it. The biggest foundational challenge is to develop an adequate naturalistic theory of how representational content is determined. Philosophers have proposed several ingenious theory-sketches of content determination but none accounts for the full range of semantic features mental representations arguably have. Another major challenge is the existence of non-representational competitor research programs. A likely future scenario is that we will be able to explain certain 'low-level' aspects of cognition without resort to representations but that representational hypotheses will still be needed to account for the intentionality-based features of cognition and 'representation hungry' higher-level processes.

Abstract: The Explanatory Gap' is a label for the idea that we cannot explain consciousness in terms of brain activity. There are many different formulations of the explanatory gap, but all discussion about it assumes that there is only one gap, which consists of the absence of a deductive explanation. This assumption is mistaken. In this paper, I show that the position that deductive explanation is privileged in this case is unmotivated. I argue that whether or not there is an explanatory gap depends on the kind of explanation in question, so there is no single, unified explanatory gap but only the absence and (perhaps) presence of different sorts of explanation.

Abstract: Representationalist solutions to the qualia problem are motivated by two fundamental ideas: first, that having an experience consists in tokening a mental representation; second, that all one is aware of in having an experience is the intentional content of that representation. In particular, one is not aware of any intrinsic features of the representational vehicle itself. For example, when you visually experience a red object, you are aware only of the redness of the object, not any redness or red quale of your experience. You are aware of outer red without being aware of inner red. According to the representationalist, the phenomenal character of your experience is just (an element of) the intentional content of your representation. In effect, inner red just is outer red. For her part, the defender of qualia, or anyway the defender of qualia who will figure in the present discussion, grants that experiencing a red object involves mentally representing it, and that when you have such an experience you are aware of its intentional content. But she denies that that intentional content exhausts your awareness. The defender of qualia (call her 'Quale') contends that your mental vehicle is itself mentally or phenomenally red, and that in addition to the outer redness of the object, you are aware of this inner redness, the intrinsic phenomenal character of your representational vehicle. Thus, contra the representationalist (call him 'Rep'), you are not aware of the content of your representation without being aware of its intrinsic features

Abstract: Dretske has recently offered a representational theory of perceptual experience - considered as paradigmatic of the qualitative and phenomenal aspects of our mental life. This theory belongs, as do his previous works, to a naturalistic approach to mental representation

Abstract: When I look at a colored object I have an experience of a specific phenomenal kind. Let us suppose I have an experience of pure blue. The blueness I see appears to be instantiated on the surface of the object. When I focus upon the specific phenomenal kind of visual experience I am having (on my having an experience of pure blue) I continue to carefully attend to the property the object appears to have and I do not direct my attention into some inner space. I do not get aware - by attending to my own experience - of the instantiation of any property I was not already aware of before I focused attention upon my own experience. These insights have been associated with the idea that perceptual experience is 'transparent' or 'diaphanous' and they have been taken to support a number of substantial philosophical claims about the nature of phenomenal states and about our capacity to attend to these states. It has been argued that these phenomenological insights support the claim that the phenomenal character of experiences consists in their representing objects as having specific properties (where representation is understood in a naturalistic manner). It also has appeared obvious to some philosophers that the so?called transparency of experience supports the following claim: either our experiences do not have an intrinsic phenomenal character or we are unable to attend to these intrinsic features. I will argue in this paper that the phenomenological insights associated with the term 'transparency of experience' do not support the philosophical consequences just mentioned. I will try to show that the contrary impression is a cognitive illusion that can be explained by reference to what one may call the perceptual model of phenomenal awareness and phenomenological reflection. This model is just a bad and misleading metaphor as everybody will agree when consciously considering the issue. Nonetheless, or so I claim, the metaphor is at work in the background of people's mind. If we assume that a philosopher is either him? or herself in the grip of that metaphor or implicitly interprets the view he wishes to attack along the lines of that metaphor, then we can see how it may appear obvious to him that the phenomenological insights associated with 'transparency' lead quite naturally to the strong philosophical claims they have been taken to support.1

Abstract: According to the experience property framework qualia are properties of experiences the subject undergoing the experience is aware of. A phenomenological argument against this framework is developed and a few mistakes invited by the framework are described. An alternative to the framework, the framework of experiential properties is presented and defended as preferable. It is argued that the choice between these two frameworks makes a substantial difference for theoretical purposes.

Abstract: Is it possible that a person who behaves just like you and me in normal life situations and applies colour words to objects just as we do and makes the same colour discriminations and colour similarity judgements that we make, see green where we see red and red where we see green? Many philosophers assert that the description of such a case is somehow incoherent. Often the motivation for this assertion is "that they suspect that admitting that claim [the possibility of such a case] will put one on a slippery slope which will eventually land one in skepticism about other minds".1 Among philosophers, however, it does not seem to be common knowledge that there is scientific evidence for the existence of such cases. Theories about the physiological basis of colour vision deficiencies together with theories about the genetics of colour vision deficiencies lead to the prediction that some people are 'pseudo- normal' (according to an estimation of Piantanida (1974) this occurs in around 14 of 10 000 males). 2 Pseudonormal people "would be expected to have normal colour vision except that the sensations of red and green would be reversed - something that would be difficult, if not impossible, to prove. ''3 Any philosophical theory of mind or more specifically about colour, colour appearances or colour concepts should meet the following plausible prima facie constraint: No hypotheses accepted or seriously considered in colour vision science should be regarded according to a philosophical theory to be either incoherent or unstatable or false. Therefore - regardless of whether the hypothesis of the existence of pseudonormal people is correct- the mere fact that the hypothesis is seriously considered in colour vision science, is philosophically relevant. Central claims of colour vision science when combined with specific empirical assumptions lead to the prediction that there are red-green-inverted people. Therefore any philosophical theory which excludes such a case does not meet the above formulated constraint. The failure to meet this prima facie constraint does not in itself justify the rejection of a philosophical proposal, but it does represent a serious objection. This kind of criticism will be advanced against some widely held philosophical proposals in the present paper. But let me begin with a short sketch of the relevant parts of colour vision science.

Abstract: Is a subject who undergoes an experience necessarily aware of undergoing the experience? According to the view here developed, a positive answer to this question should be accepted if 'awareness' is understood in a specific way, - in the sense of what will be called 'primitive awareness'. Primitive awareness of being experientially presented with something involves, furthermore, being pre-reflectively aware of oneself as an experiencing subject. An argument is developed for the claims that pre-reflective self-awareness is the basis of our understanding of what it is to be an experiencing subject and that that understanding reveals what being an experiencing subject consists in and what it is for experiences to belong to one single experiencer. Claim is used in an argument in favor of the so-called simple view with respect to synchronic and diachronic unity of consciousness.

Abstract: Free action and microphysical determination are incompatible but this is so only in virtue of a genuine conflict between microphysical determination with any active behavior. I introduce active behavior as the veridicality condition of agentive experiences and of perceptual experiences and argue that these veridicality conditions are fulfilled in many everyday cases of human and non-human behavior and that they imply the incompatibility of active behavior with microphysical determination. The main purpose of the paper is to show that the view proposed about active behavior leads to a natural compromise between libertarianism and compatibilism, which avoids the flaws of both positions while preserving their central insights.

Introduction: Everyone familiar with the current mind-body debate has probably heard about Frank Jackson's neurophysiologist Mary. So I tell her story very briefly. Mary knows everything there is to know about the neurophysiological basis of human colour vision but she never saw colours herself (she always lived in a black-and-white environment). When Mary is finally released into the beauty of the coloured world, she acquires new knowledge about the world and - more specifically - about the character of the visual experiences of others. This appears clear at first sight. In the ongoing philosophical debate, however, there is no agreement about whether Mary really gains new knowledge and about whether this would, if it were so, represent a problem for physicalism. Those who defend the so-called argument from knowledge (or 'knowledge argument') think that it does.
