Phenomenal consciousness can be conceptualized innocently enough that its existence should be accepted even by philosophers who wish to avoid dubious epistemic and metaphysical commitments such as dualism, infallibilism, privacy, inexplicability, or intrinsic simplicity. Definition by example allows us this innocence. Positive examples include sensory experiences, imagery experiences, vivid emotions, and dreams. Negative examples include growth hormone release, dispositional knowledge, standing intentions, and sensory reactivity to masked visual displays. Phenomenal consciousness is the most folk-psychologically obvious thing or feature that the (...) positive examples possess and that the negative examples lack, and which preserves our ability to wonder, at least temporarily, about antecedently unclear issues such as consciousness without attention and consciousness in simpler animals. As long as this concept is not empty, or broken, or a hodgepodge, we can be phenomenal realists without committing to dubious philosophical positions. (shrink)

The consciousness studies are unavoidably linked to the mind-body problem, as most of the researchers are trying to investigate how a physical system generates mental property. To get around this problem the researchers often seem to endorse physicalism and identity theory but it is not clear to what extent, if any, does the research practice or the evidence based theories of consciousness depend on such assumptions. Here, we provide a few examples of studies investigating the so-called Neural Correlates of Consciousness. (...) Based on these examples and the contents of the methodological papers addressing the problem of identifying the NCCs, we provide a novel, operational definition of the NCC. This allows us to shed some light on the meaning of various claims about the causal role of consciousness within the field of empirical studies. We also provide an inference rule for identifying the NCCs and the exhaustive list of the NCC confounders in the typical research paradigms. (shrink)

Introspection used to be excluded from science because it isn?t public--for any question about mental states, only the person whose states are in question can answer by introspecting. However, we often use introspective reports to gauge each other?s minds, and contemporary psychologists generate data from them. I argue that some uses of introspection are as public as any scientific method.

Functionalists in philosophy of mind traditionally raise two major arguments against the type identity theory: (1) psychological states are _multiply realizable_ so that there are no one-to-one mappings of psychological states onto neural states and (2) the most that evidence could ever establish is the _correlation_ of psychological and neural states, not their identity. We defend a variant on the traditional type identity theory which we call _heuristic identity theory_ (HIT) against both of these objections. Drawing its inspiration from scientific (...) practice, heuristic identity theory construes identity claims as hypotheses that guide subsequent inquiry, not as conclusions of the research. (shrink)
