 Generally, those who, like informational theorists, think relations to one’s (natural or social) environment are (at least partially) determinative of the content of mental representations are externalists, or anti-individualists (e.g., Burge 1979, 1986b, 2010, McGinn 1977), whereas those who, like some proponents of functional theories, think representational content is determined by an individual’s intrinsic properties alone, are internalists (or individualists; cf. Putnam 1975, Fodor  1981c).[5]
