Thanks for laying this out. I'm one of the people who thinks philosophical zombies don't make sense, and now I understand why-- they seem like insisting that a result is possible while eliminating the process which leads to the result.

This doesn't explain why it's so obvious to me that pz are unfeasible and so obvious to many other people that pz at least make enough sense to be a basis for argument. Does the belief or non-belief in pz correlate with anything else?
