6. Throughout, I ignore the distinction between narrow and wide content (i.e., individualism vs. externalism, etc.) because I believe that issue is mostly orthogonal to the present set of issues (with the exception of the view criticized in fn. 15.) Functional role theorists who think that most content is wide include Block's (1986, 1987) "two-factor" theory, and Harman's (1987) "non-solipsistic" theory. [Personally, I'm an individualist.]
