Abstract

We defend Laurence Nemirow’s and David Lewis’s Ability Hypothesis against Paul Raymont’s criticisms in defense of Jackson’s Knowledge Argument. According to the Ability Hypothesis, what Mary lacked when she was in her black-and-white room was a set of abilities; she did not know how to recognize or imagine certain types of experience. Her subsequent discovery of what it is like to experience color amounts to no more than her acquiring these abilities. Appealing to the Molyneux test, Raymont has argued that knowledge of what an experience is like cannot be equated with the possession of any set of abilities, since one can be in possession of a recognitional ability concerning a certain type of experience without knowing what that experience is like. We argue that the intermodal recognitional ability in the Molyneux test and similar ones depends on previous experience and thus makes an implicit appeal to knowledge of what it is like.
