 A similar example is used for the same purpose and discussed in more detail by Raymont 1999. Raymont argues that mnemic, recognitional and imaginative abilities neither separately nor conjointly amount to knowing of what it is like to have a particular kind of experience. He first argues that none of these abilities is necessary and sufficient for knowing what it is like: (a) Mnemic abilities are not necessary, since someone can learn what an experience is like when first having it without already remembering an experience of the relevant kind. (b) Imaginative abilities are not sufficient since someone can have the ability to imagine a particular kind of experience without exercising it (see the example cited above). (c) To show that recognitional abilities are not sufficient either, Raymont cites empirical data “in support of the view that one can have the ability to noninferentially recognize a certain type of visual experience without ever having had it, and thus without knowing what it is like to have it”. But then these three kinds of abilities cannot conjointly amount to knowing what it is like either: if they did, then – contrary to (a) – each of them would have to be a necessary condition for knowing what it is like.
