I guess I don't really have a clear picture of why the fact that any  
computation can be mapped onto a physical state should lead to the  
belief that (say) those mappings somehow support consciousnesses. I'm  
not very comfortable with the idea that a stone implements all  
computations. It may in fact be the case that those views are  
functionally equivalent to my suggestion that mathematical facts of  
the matter play the role that physical existence is supposed to play  
for the materialist, but I'm sticking with the latter formulation,  
because that's the one I actually understand.
