This paper controverts the ability of intentionalism about perception to account for unique epistemic significance of phenomenal consciousness. More specifically, the intentionalist cannot explain the latter without denying two well-founded claims: the transparency of experience, and the possibility of unconscious perception. If they are true, intentionality of perception entails that phenomenal consciousness has no special epistemic role to play. Although some intentionalists are ready to bite this bullet, by doing so they effectively undermine one of the standard motivations of their (...) view, i.e. the claim that perceptual experiences justify beliefs. Consequently, whatever reason might there be to think that phenomenal consciousness has unique epistemic import, it is also a reason to reject intentionalism. I recommend replacing the latter with an unorthodox formulation of relationalism about perception. (shrink)

Brain activity determines which relations between objects in the environment are perceived as differences and similarities in colour, smell, sound, etc. According to selectionism, brain activity does not create those relations; it only selects which of them are perceptually available to the subject on a given occasion. In effect, selectionism entails that perceptual experience is diaphanous, i.e. that sameness and difference in the phenomenal character of experience is exhausted by sameness and difference in the perceived items. It has been argued (...) that diaphaneity is undermined by phenomenological considerations and empirical evidence. This paper considers five prominent arguments of this sort and shows that none of them succeeds. (shrink)

The present paper was written as a contribution to ongoing methodological debates within the NCC project. We focus on the neural correlates of conscious perceptual episodes. Our claim is that the NCC notion, as applied to conscious perceptual episodes, needs to be reconceptualized. It mixes together the processing related to the perceived contents and the neural substrate of consciousness proper, i.e. mechanisms making the perceptual contents conscious. We thus propose that the perceptual NCC be divided into two constitutive subnotions. The (...) main theoretical idea that emerges as a consequence of this reconceptualization is that the neural correlate of a perceptual episode is formed in the neural interaction between content-processing and consciousness-conferring mechanisms. The paper elaborates this distinction, marshals some initial arguments in its favour, and tests it against some of the most debated theories of consciousness. (shrink)

Even after many years of empirical and conceptual research there are underlying controversies which lead scholars to dispute identity theory. One of the most influential examples is Kripke’s modal argument leading to the rejection of the claim that pain and C-fibres firing are identical. The aim of the first part of the paper is to expose that Kripke does not rigorously distinguish the meaning of individual relata entering the identity relation, and therefore his claim about the faultiness of the analogy (...) between propositions “heat is molecular motion”, and “pain is C-fibres firing”, is mistaken. Moreover, whilst much emphasis within metaphysics of mind-brain relations has been placed upon conscious phenomenal states, it might be worthwhile to also consider cases of unconscious phenomenal states. If one admits the unconscious phenomenal states, such as unconscious pain, then, Kripke’s claim is further discredited by the fact that even pain can be individuated through its contingent property. Identity statements about pain could therefore be analogous to any other identity statements. The second part of the paper focuses on the relevance of the modal argument in confrontation with empirical evidence. It argues against the assumption embedded in the modal argument that an identical neurobiological pattern occurs regardless of whether conscious pain is present or completely absent. (shrink)

The paper argues that a coherent strong Phenomenal Intentionality Theory (sPIT) needs to adopt the concept of unconscious phenomenality. sPIT is based on the thesis that phenomenal properties constitute intentional episodes. But if “constitutive” means that without these phenomenal properties, intentional episodes break down, then this poses a serious problem for so-called unconscious intentional occurrent episodes. The dilemma is that sPIT either preserves unconscious intentional states, but then must reject constitutiveness, or conversely, sPIT accepts constitutiveness but must acknowledge unconscious phenomenality. (...) It is argued that the second option – i.e. accepting unconscious phenomenality – offers an interesting way to preserve sPIT. This counterintuitive solution is labeled a “dual model” here. Accepting the dual model not only as a conceptual possibility but as a factual case – supported by conceptual and empirical arguments – could be a plausible proposal for solving the dilemma.

According to unconscious perception hypothesis (UP), mental states of the same fundamental kind as ordinary conscious seeing can occur unconsciously. The proponents of UP often support it with empirical evidence for a more specific hypothesis, according to which colours can be seen unconsciously (UPC). However, UPC is a general claim that admits of many interpretations. The main aim of this paper is to determine which of them is the most plausible. To this end, I investigate how adopting various conceptions of (...) colour and perceptual phenomenal character affects UPC’s resilience to objections. This brings me to the conclusion that the most plausible reading of UPC is the one according to which the phenomenal character of colour perception (i) is constituted by colours qua primitive mind-independent qualities of the environment and (ii) is not essentially tied to consciousness. My conclusion not only identifies the most plausible interpretation of UPC, but also highlights and supports an unorthodox version of the relational theory of perception, which is a perfectly viable yet so far overlooked stance in the debate about unconscious perception.

One of the greatest challenges of consciousness research is to understand the relationship between consciousness and its implementing substrate. Current research into the neural correlates of consciousness regards the biological brain as being this substrate, but largely fails to clarify the nature of the brain-consciousness connection. A popular approach within this research is to construe brain-consciousness correlations in causal terms: the neural correlates of consciousness are the causes of states of consciousness. After introducing the notion of the neural correlate of (...) consciousness, we argue (see Against Causal Accounts of NCCs) that this causal strategy is misguided. It implicitly involves an undesirable dualism of matter and mind and should thus be avoided. A non-causal account of the brain-mind correlations is to be preferred. We favor the theory of the identity of mind and brain, according to which states of phenomenal consciousness are identical with their neural correlates. Research into the neural correlates of consciousness and the theory of identity (in the philosophy of mind) are two major research paradigms that hitherto have had very little mutual contact. We aim to demonstrate that they can enrich each other. This is the task of the third part of the paper in which we show that the identity theory must work with a suitably defined concept of type. Surprisingly, neither philosophers nor neuroscientists have taken much care in defining this central concept; more often than not, the term is used only implicitly and vaguely. We attempt to open a debate on this subject and remedy this unhappy state of affairs, proposing a tentative hierarchical classification of phenomenal and neurophysiological types, spanning multiple levels of varying degrees of generality. The fourth part of the paper compares the theory of identity with other prominent conceptions of the mind-body connection. We conclude by stressing that scientists working on consciousness should engage more with metaphysical issues concerning the relation of brain processes and states of consciousness. Without this, the ultimate goals of consciousness research can hardly be fulfilled. (shrink)
