 However, though Raftopoulos and Müller attempt to argue that insulation from the propositional attitudes of the person is a necessary and sufficient condition for any representation to have nonconceptual content, this does not seem to be the case with representations in general and certain personal level representations in particular. At least with regards to personal level representations, Tye (1995) argues that one’s conceptual capacities often are involved in determining the content of a perceptual representation, and yet that the content of that representation is nonconceptual. This is the case, for example, in the process of perceptually disambiguating an ambiguous figure (e.g., the two faces/vase figure). Though the production of a disambiguated perceptual representation (e.g., experiencing the figure as a vase) might involve more than merely information recovered bottom-up (e.g., it might employ the concept vase), it does not follow that the resulting perception is conceptual. This is so since for the content of a representation to be nonconceptual it merely needs to be the case that one can undergo a state with such representational content without possessing the concepts that enter into a correct specification of its content, and it seems reasonable that one can undergo the same disambiguated experience of the figure without possessing any concepts (and in particular, without possessing the concept vase).
