Abstract

It is well known that, according to some, philosophical reflection on zombies (i.e., bodies without minds) poses a problem for physicalism. But what about ghosts, i.e., minds without bodies? Does philosophical reflection on them pose a problem for physicalism? Descartes, of course, thought so, and lately rumours have been surfacing that has was right after all, that ghosts pose a problem for both a priori and a posteriori physicalism, and for any kind of physicalism in between. This paper argues that physicalists have nothing to fear from ghosts, since the central consideration employed to motivate ghostly arguments against physicalism--viz., that ghosts are conceivable--is false: ghosts aren't conceivable.
