 An advantage of many-minds theory over DeWitt’s original version of the many-worlds theory is that there is no need for a physically preferred basis here. One must choose a preferred basis in order to specify the mental dynamics completely but this choice has nothing to do with any physical facts; rather, it can simply be thought of as part of the description of the relationship between physical and mental states. Another advantage of the many-minds theory is that, unlike the standard variety of many-worlds theories where worlds and observers split and are copied in measurement-like interactions, the many-minds theory simply predicts the standard forward-looking quantum probabilities for the future experiences of each particular mind. This, of course, requires one to understand the minds as having transtemporal identities, which Albert and Loewer clearly do as part of their unabashed commitment to a strong mind-body dualism. Finally, the many-minds theory is one of the few formulations of quantum mechanics that are manifestly compatible with special relativity. (For a discussion of why it is difficult to solve the quantum measurement problem under the constraints of relativity see Barrett 2000 and 2002, for discussions of locality in the many minds theory, see Hemmo and Pitowski 2003, and Bacciagaluppi 2002, and for the relationship between relativity and the many worlds theory see Bacciagaluppi 2002.)
