 It is plain that there is nothing deeply problematic about functionally-definable notions of mental-state consciousness, from a naturalistic perspective. For mental functions and mental representations are the staple fare of naturalistic accounts of the mind. But this leaves plenty of room for dispute about the form that the correct functional account should take. Some claim that for a state to be conscious in the relevant sense is for it to be poised to have an impact on the organism’s decision-making processes (Kirk 1994; Dretske 1995; Tye 1995, 2000), perhaps also with the additional requirement that those processes should be distinctively rational ones (Block 1995). Others think that the relevant requirement for access-consciousness is that the state should be suitably related to higher-order representations—experiences and/or thoughts—of that very state (Armstrong 1968, 1984; Rosenthal 1986, 1993, 2005; Dennett 1978a, 1991; Carruthers 1996, 2000, 2005; Lycan 1987, 1996; Gennaro 2012).
