A common objection to sense-datum theories of perception is that they cannot give an adequate account of the fact that introspection indicates that our sensory experiences are directed on, or are about, the mind-independent entities in the world around us, that our sense experience is transparent to the world. In this paper I point out that the main force of this claim is to point out an explanatory challenge to sense-datum theories.

The aim for this thesis is to motivate, critically evaluate and defend the claim that subjects are able to consciously perceive the affordances of objects. I will present my protagonist, the ‘Conscious Affordance Theorist’, with what are two main obstacles to this claim. The first of these is that affordance perception correctly understood refers only to a kind of subpersonal visual processing, and not to a kind of conscious visual experience. I claim that this results in an explanatory gap at (...) the level of intentional action, which in order to correct we need to redefine the notion of affordance perception to include conscious as well as subpersonal affordance perception. Precisely, I claim that ‘affordance awareness’ has a crucial epistemological role to play, and that subjects must be able to consciously experience affordances in order to gain this awareness. In answer to this claim, I supplement the objection that affordance perception is defined as subpersonal perception to include the claim that any awareness subjects have of the affordances of objects they visually experience is due to them having thoughts about those affordances, and not visual experience of them. I then consider the Conscious Affordance Theorist’s response to this supplemented account. The second obstacle is the claim that conscious visual affordance perception is an impossible notion given that affordances are dispositional properties, and the dispositional properties of objects cannot be ‘seen’. In facing this objection I look to the supporting claims and motivations that lie behind it, in order to find a way for the Conscious Affordance Theorist to challenge its central claim that affordances cannot be seen. I end this thesis with an account of the Conscious Affordance Theorist’s own positive position, and a consideration of how his account has the ability to provide for conscious affordance perception in the case of non-human animals.

There are now various approaches to understand where and how in the brain consciousness arises from neural activity, none of which is universally accepted. Difficulties among these approaches are reviewed, and a missing ingredient is proposed here to help adjudicate between them, that of ''perspectivalness.'' In addition to a suitable temporal duration and information content of the relevant bound brain activity, this extra component is posited as being a further important ingredient for the creation of consciousness from neural activity. It (...) guides the development of what is termed the ''Central Representation,'' which is supposed to be present in all mammals and extended in humans to support self-consciousness as well as phenomenal consciousness. Experimental evidence and a theoretical framework for the existence of the central representation are presented, which relates the extra component to specific buffer working memory sites in the inferior parietal lobes, acting as attentional coordinators on the spatial maps making up the central representation. The article closes with a discussion of various open questions. (shrink)

The objectives of this article are twofold. First, by denying the dualism inherent in attempts to load metaphysical significance on the inner/outer distinction, it defends the view that scientific investigation can approach consciousness in itself, and is not somehow restricted in scope to the outward manifestations of a private and hidden realm. Second, it provisionally endorses the central tenets of global workspace theory, and recommends them as a possible basis for the sort of scientific understanding of consciousness thus legitimised. However, (...) the article goes on to argue that global workspace theory alone does not constitute a fully worked-out objective account of the conscious subject. This requires additional attention to be paid to the issue of embodiment, and to the possibility of indexicality that arises when an instantiation of the global workspace architecture inhabits a spatially localised body.

This paper is trying to show that it is not possible to use the Knowledge argument as independent evidence for the form of non-reductionism the Modal argument argues for. To show this, Jackson's famous 'Mary' thought experiment is imagined in a zombie world. This leads to the result that there are many problems in the Mary experiment, which cannot have anything to do with phenomenal Qualia, because the Zombie-Mary would encounter them as well, and once all these problems are accounted (...) for, it is no longer clear whether a Zombie-Mary is conceivable at all. Finally, an alternative explanation for the strong non-reductive intuitions of the Mary experiment is discussed. (shrink)

Situation theorists such as John Barwise, John Etchemendy, John Perry and François Recanati have put forward the hypothesis that linguistic representations are situated in the sense that they are true or false only relative to partial situations which are not explicitly represented as such. Following Recanati's lead, I explore this hypothesis with respect to mental representations. First, I introduce the notion of unarticulated constituent, due to John Perry. I suggest that the question of whether there really are such constituents should (...) divide in two issues, one concerning language and the other concerning thought. Then I formulate a dilemma that any friend of cognitive unarticulated constituents must face: alleged unarticulated constituents seem to be either articulated or non-constituents after all. The dilemma is strengthened by the fact that unarticulated constituents cannot be inferentially relevant. In §4, three constraints on entertaining situated representations are spelled out. First, although the situation within which one is immersed is not represented as such, there must be cognitive facts that make immersion possible, and explain why one is implicitly related to a particular situation as opposed to another. Second, the move from a given representation to one which articulates the situation requires the capacity to contrast the latter with others in the same range. Third, I suggest that conceptual representations differ from non-conceptual ones in the permanent possibility of detachment that they allow. I then illustrate how these constraints work in three sorts of cases. In the first, thoughts like It's raining and It's over are implicitly related to their situations via some practical capacity of keeping track of particular places or times. In the second sort of cases, the relevant situations are not given, but stipulated, like in In Constance, it's raining. Cases of the third sort are those in which an unarticulated constituent is relevant to a whole system of representations, for instance the perceptual system. In the last section, I use the notion of ad hoc representation to defend the cognitive application of situation semantics against an important objection. (shrink)
