 All part-whole self-representational accounts differ from the dual-content theory of Carruthers (2000, 2005) in the following way, however: on Carruthers’ account, the end-product can be entirely non-conceptual. And in particular, the higher-order content possessed by a conscious percept is a non-conceptual one, representing a seeming of the first-order content of the state by virtue of its availability to higher-order consumer systems. On all of the part-whole accounts sketched above, in contrast, a conscious perception is always partially conceptual, containing the higher-order concept experience (or something similar) as part of its content. There are probably multiple dimensions along which these two sorts of theory could be compared, and each may have its own advantages.
