It shall be examined how anti-physicalist arguments give rise to the tension between those aspects of our everyday life and the thesis of physicalism. The debate over the subjective character of consciousness, or as it is sometimes called: “the hard problem of consciousness”, is considered to be the greatest challenge to physicalism. Many philosophers posit this as a matter that cannot be solved, regardless of scientific progress, for it is beyond the scope of what science can find out about the (...) world. If they are correct, the consequence is that the idea of physicalism itself fails. The paper is divided in two parts. For the first part we will deal with Chalmers’ version of the conceivability argument as well as the semantic apparatus of the two-dimensional framework required to make the appropriate link between conceivability and possibility. At the end of this we shall take a look at Kripke’s version of the conceivability argument against physicalism. (shrink)

Chalmers’s two-dimensional argument against materialism (aka the zombie argument) is arguably the most ingenious attempt to ground a view about fundamental reality on epistemic considerations. From the conceivability of a being that is physically identical to a conscious being but that is deprived of phenomenal consciousness (a zombie), the argument draws on the interplay of the primary and the second intensions of the zombie hypothesis to infer the metaphysical possibility of a zombie world, and thus the falsity of physicalism about (...) phenomenality. By means of a detailed reconstruction of the two-dimensional argument, the paper tries to isolate its most central assumption: that the role played by an epistemic scenario (an intentional object) in the verification of the zombie hypothesis is played by a nonintentionally individuated metaphysical world (the zombie world) considered as actual. The paper argues that no non-viciously circular case for this assumption has been made. Thus, the two-dimensional argument is at best inconclusive. (shrink)
