The first question should really be: what does the apparent conceivability of zombies by humans imply about their possibility?

Philosophers on your side of the debate seem to take it for granted (or at least end up believing) that it implies a lot, but those of us on the other side think that the answer to the cogsci question undermines that implication considerably, since it shows how we might think zombies are conceivable even when they are not.

It's been quite a while since I was actively reading philosophy, so maybe you can tell me: are there any reasons to believe zombies are logically possible other than people's intuitions?
