Several subjects are fully convinced that they are brains in vats whose experiences are hallucinatory. They confront a ‘skeptic’ who raises the possibility that they are not brains in vats who lack and hallucinate hands but ‘brains in skulls’ who have hands and see them. Familiar responses to skepticism are offered in support of the claim that the subjects know they do not have hands. The philosophical significance of this looking-glass approach to skepticism is also discussed. It is suggested that these familiar responses to skepticism do not achieve anything because, if we begin from the assumption that we are brains in vats, we can employ those same responses to skepticism to support the claim that we know we do not have hands. One interlocutor argues that things are not so dismal. The main conversation is framed by a discussion among night watchmen at some sort of skepticism laboratory.

Sorensen raises the issue of whether it is logically possible to fake Munchausen's syndrome by way of a fictional exchange between a physician and an insurance company. In this paper, it is shown that it is possible to fake Munchausen's syndrome and to fake faking Munchausen's syndrome. The implications of this on deeper philosophical issues such as Lewis' puzzle of iterated pretence and “internalist” versus “externalist” accounts of faking are discussed. An externalist account of faking is defended and offered as a solution to Lewis' puzzle as it arises in this context
