 Within this framework, it is easy to resolve the puzzles we addressed at the top of the section. If I believe that BW is a crook, I self-ascribe the property of inhabiting a world in which BW is a crook. (On Lewis’s theory, beliefs that are not explicitly self-locating will be beliefs about which world one is in.) If I believe I am not a crook, I self-ascribe the property of not being a crook. Since there are possible individuals who are (a) not crooks but (b) in worlds where BW is a crook, this is a consistent self-ascription. Indeed, I may even have strong evidence that I have both of these properties. So there is no threat of inconsistency, or even irrationality here.
