Hugh - "Do you take Taoism to commit one to the view that ‘phenomenal consciousness’ is everywhere –something like that?"
 
Something like that, yes, but it needn't be such a deep point. There are various ways in which the existence of zombies would be counterevidence for mysticism's view of human nature. For instance, human behaviour would be motivated by desires and moderated by beliefs (as for Popper), while a zombie would know nothing of desires and beliefs.    

I also don't think that Chalmers rejects the possibility that the Taoist view is correct. In fact I read him as saying that it is correct, since it is the only view by which there would be the extra ingredient in the mind-matter problem that he proposes would be necessary for a solution. Thus there is no mind-matter dilemma in mysticism. This may be an issue that deserves more of his attention, given his conclusion that neither mind or matter is fundamental. Only for mysticism would they have a dependent and contingent existence. Hence Barkin calls this view 'relative phenomenalism'. 

Sorry if this is OT here.
