ABSTRACT. In this paper I argue that David Chalmers' argument against John Searle concerning the sorts of physical systems in which consciousness can emerge is a new version of an old objection-one that has already been convincingly responded to by Searle-namely, the "brain-simulator" objection. Moreover, I believe Chalmers' argument, although interesting, ultimately fails to address his question, namely "What sort of physical systems can give rise to conscious experience?"
