Zombies
First published Mon Sep 8, 2003; substantive revision Mon Oct 9, 2006
Zombies are exactly like us in all physical respects but have no conscious experiences: by definition there is ‘nothing it is like’ to be a zombie. Yet zombies behave like us, and some even spend a lot of time discussing consciousness. This disconcerting fantasy helps to make the problem of phenomenal consciousness vivid, especially as a problem for physicalism.
Few people think zombies actually exist. But many hold they are at least conceivable, and some that they are ‘logically’ or ‘metaphysically’ possible. It is argued that if zombies are so much as a bare possibility, then physicalism is false and some kind of dualism must be accepted. For many philosophers that is the chief importance of the zombie idea. But the idea is also of interest for its presuppositions about the nature of consciousness and how the physical and the phenomenal are related. Use of the zombie idea against physicalism also raises more general questions about relations between imaginability, conceivability, and possibility. Finally, zombies raise epistemological difficulties: they reinstate the ‘other minds’ problem.
