Abstract

The definition of zombies is clarified, and the main arguments for the alleged possibility of zombies are examined. The ‘conceivability argument’ is influential: zombies are conceivable; whatever is conceivable is possible; therefore zombies are possible. Chalmers’s arguments for conceivability are given special attention, notably his use of Block’s homunculus-head; the apparent gap between physical information and facts about experiences; Jackson’s ‘knowledge argument’; and the argument from the ‘absence of analysis’. It is argued that none of the arguments is conclusive.
