 On the other hand, the externalist individuation of intentional states may fail to capture some important psychological commonalities between ourselves and our counterparts that are relevant to the explanation of behavior. If my Twin Earth counterpart and I have both come in from a long hike, declare that we're thirsty, say “I want some water” and head to the kitchen, it seems that our behavior can be explained by citing a common desire and belief. Some theorists, therefore, have suggested that functional theories should attempt merely to capture what has been called the “narrow content” of beliefs and desires — that is, whichever representational features individuals share with their various Twin Earth counterparts. There is no consensus, however, about just how functionalist theories should treat these “narrow” representational features (Block 1986; Loar 1987, Yli-Vakkuti and Hawthorne, 2018), and some philosophers have expressed skepticism about whether such features should be construed as representations at all (Fodor 1994; also see entry on Narrow Content). Even if a generally acceptable account of narrow representational content can be developed, however, if the intuitions inspired by “Twin Earth” scenarios remain stable, then one must conclude that the full representational content of intentional states cannot be captured by “narrow” functional characterizations alone (and this will be true as well for certain sorts of qualitative states, e.g. color experiences, if they too have representational content).
