 Once these two steps are clearly distinguished one may conclude that Marianna’s relevant epistemic progress at t3 (and Mary’s relevant progress after release) is not happily described by talk of knowing what it’s like. Rather, or so one may argue, Mary and Marianna acquire a particular kind of belief that the sky appears blue to normal perceivers, namely the phenomenal belief that it appears blue to normal perceivers, where phenomenal belief involves the application of the appropriate phenomenal concept. Both may have believed, in a sense (the non-phenomenal sense that does not require use of phenomenal concepts) that the sky appears blue to normal perceivers while still in their black-and-white environment (they may have been told so by their friends). (For the distinction between phenomenal and non-phenomenal belief see Nida-Rumelin 1996 and 1998).
