Quantum mechanics without the collapse postulate, the bare theory, was
proposed by Albert (1992) as a way of understanding Everett's relativ
e-state formulation of quantum mechanics. The basic idea is to try to
account for an observer's beliefs by appealing to a type of illusion p
redicted by the bare theory. This paper responds to some recent object
ions to the bare theory by providing a more detailed description of th
e sense in which it can and the sense in which it cannot account for o
ur experience.
