 Wollheim interprets Gombrich as claiming that a spectator cannot be simultaneously conscious of the marks on a picture’s surface and the scene it represents, and that these can only be objects of alternating perceptions, although Gombrich does not say this explicitly (Wollheim 1963; cf. Bantinaki 2007). But according to Wollheim himself, simultaneous awareness of surface and content is precisely what is distinctive about the experience of seeing a picture. Furthermore, these are two distinguishable but “inseparable” aspects of a single visual experience, and not two experiences somehow combined (Wollheim 1987, 1998, 2003a,b; Wollheim does not attempt to define a criterion of identity for experiences, so this claim is difficult to assess). Thus, the experience of seeing a picture has a sui generis phenomenology, which Wollheim calls “twofoldness”. The two aspects of this experience—its configurational aspect and its recognitional aspect—are held to be psychologically real and to be integrated in a way that also affects the phenomenal character of the experience as a whole.
