From a Flaw in the Knowledge Argument to a Physicalist Account of Qualia

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.
