  There is considerable infelicity in Fodor’s choice of terms. He is able to offer a cogent account of why methodological individualism counts as a methodological constraint. He argues that the desire to align terminological distinctions with objects having different causal powers is “one which follows simply from the scientist’s goal of causal explanation and which, therefore, all scientific taxonomies must obey” (1987, 42). Thus it is a methodological precept. (Although one can see clearly here the stark contrast between Fodor’s use of the term and that of Weber or Hayek, for whom the ability of the social scientist to provide something beyond merely causal explanation was what imposed the methodological commitment to the action-theoretic level of analysis.) It is simply unclear why Fodor chooses to call it individualism. With methodological solipsism, on the other hand, one can see why he calls it solipsism, but it is unclear what makes it methodological. Indeed, Fodor goes on to state that “solipsism (construed as prohibiting the relational taxonomy of mental states) is unlike individualism in that it couldn’t conceivably follow from any general considerations about scientific goals and practices. ‘Methodological solipsism’ is, in fact, an empirical theory about the mind.”(1987, 43). Thus in Fodor’s use of the terms, “methodological individualism” is not really individualistic, and “methodological solipsism” is not really methodological.
