The Knowledge argument based on the grey Mary thought experiment cannot be claimed as a basis for rejecting physicalism. First, because it is flawed, being so formulated as to predetermine the outcome of the thought experiment in favour of a refutation of physicalism. Second, because, once this is recognised, it becomes clear that there is one - and only one - account of the qualia-physical relationship that will permit physicalism to survive the thought experiment itself. It is suggested that the (...) position in question is worthy of further consideration as a reasonable candidate theory for a physicalist account of qualia. (shrink)

It is widely accepted that conscious experience has a physical basis. That is, the properties of experience (phenomenal properties, or qualia) systematically depend on physical properties according to some lawful relation. There are two key questions about this relation. The first concerns the strength of the laws: are they logically or metaphysically necessary, so that consciousness is nothing "over and above" the underlying physical process, or are they merely contingent laws like the law of gravity? This question about the strength (...) of the psychophysical link is the basis for debates over physicalism and property dualism. The second question concerns the shape of the laws: precisely how do phenomenal properties depend on physical properties? What sort of physical properties enter into the laws' antecedents, for instance; consequently, what sort of physical systems can give rise to conscious experience? It is this second question that I address in this paper. (shrink)
