UPDATE: From Overcoming Bias Zombies! Zombies? and Zombie Responses.

We first had the dispute over “zombies” in this post at his blog. It has now continued in this one and this one. HA has said he likes to frame every dispute by asking how to make it an empirical question, and that is what I have done in the last link. Completely coincidentally, in his latest post on reductionism at Overcoming Bias, Eliezer Yudkowsky tangles in the comments with Richard from Philosophy Etc over the conceptual/logical possibility of zombie worlds. I think Daniel Dennet’s position is the same as mine, although I like to phrase it as “Our world is a zombie world”.
