 There are other responses to analogous absent qualia arguments that are prominent in the literature, but the target of those arguments is broader. Block's argument was initially presented as a challenge exclusively to functionalist theories, both analytic and empirical, and not generally to physicalistic theories of experiential states; the main concern was that the purely relational resources of functional description were incapable of capturing the intrinsic qualitative character of states such as feeling pain, or seeing red. (Indeed, in Block's 1980b, p. 291, he suggests that qualitative states may best be construed as “composite state[s] whose components are a quale and a [functional state],” and adds, in an endnote (note 22) that the quale “might be identified with a physico-chemical state”.) But there are similar objections that have been raised against all physicalistic theories of experiential states that are important to consider in evaluating the prospects for functionalism. These will be discussed in the next two sections.
