 It is interesting to see that one version of the New Knowledge/Old Fact View is very similar in spirit to the Acquaintance Hypothesis. Bigelow and Pargetter (1990) argue that Mary’s progress after release consists in the fact that she now stands in a new acquaintance relation to color qualia, but their theory about the individuation of beliefs implies that she thereby acquires new factual knowledge. Different beliefs, according to Bigelow and Pargetter, can be distinguished appropriately only if one takes into consideration the way the subject is acquainted with the individuals and properties her belief is about (they use the technical term “modes of acquaintance” in that context).
