 Another example of a view positing multiple contents for multiple explanatory purposes is Shoemaker’s theory of color experience, according to which experience represents both color properties, partly in virtue of representing associated ‘appearance properties’ (see  Section 4.1  for discussion). The representation of appearance properties is supposed to explain the phenomenal sameness of certain experiences with inverted qualia; whereas the representation of color properties is supposed to underlie intuitions about the veridicality of the experiences. (This is explained more fully in  Section 4.1).  A somewhat similar rationale is given for a form of ‘two-dimensionalism’ about experience contents, which holds that experiences have both indexical Fregean contents, and non-Fregean contents (either Russellian or unstructured) determined by the Fregean contents in conjunction with select facts about the environment in which the experience is had (Chalmers 2004, Thompson 2003). The indexical Fregean contents are supposed to reflect the inferential role and phenomenology of experience, while the non-Fregean contents are supposed to reflect the properties that we take experiences to attribute to objects. A related two-dimensionalist position (Chalmers 2006) adds a third kind of Russellian content to experience, ‘Edenic’ content, involving special non-instantiated ‘Edenic’ properties, which are supposed to reflect phenomenology perfectly—unlike indexical Fregean content, which is supposed to reflect it only imperfectly.
