Zombie wars

the zombie wars are well and truely reignighted the following seem to be the main points

1) P and NP should be expanded out so that htey are 'de re" as opposed ot 'de dicto' RB qwould like this to be done to the base facts and RC would prefer it jsut to stop at an arbitrary common moddle ground

Problem is I dont think (and I presume RB would agree) there is any possible meaningful middle ground. Under Reductionism if the "ultimate truthmakers" say Q is impossible so to does any other list of complete facts. that is why knowing that the UT disprove P~Q would be useful.
RC on the other hand would take that as long as there was some tension there between the apparent description at the mid level and the UT description he might get a little intuitive leverage and thus give his argument some sort of 'dialectic effectiveness'.

2) The Zombie argument seems to be stronger when phrased as a reducitonist argument

This might be an illusion of the fact that Richard is a hard core non-reducitonist, but he seems to reject the standard zombie argument which is a interesting development in itself.

To take the metaphore of a war a bit further the argument seems to feature RC retreating from all the usual psoitions and drawing RB to follow him down a narrow path. If the strategy works I suppose you catch the enemy over extended fighthing a battle they didnt expect to fight at the beginning. Dont know if that would happen or not.
