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 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. (shrink)
