  The problem that this creates for the doctrine of methodological individualism is readily apparent. A social science that aims at interpretation, or that uses interpretation as part of the centerpiece of its explanatory strategy, has a very clear methodological reason for privileging explanations that refer to individual actions – since it is precisely the underlying intentional states that serve as the object of interpretation. But if social scientists are merely in the business of providing causal explanations, just like natural scientists, then what is the rationale for privileging individual actions in these explanations? There no longer appears to be any methodological reason for doing so.  Thus critics like Leon Goldstein (1958), and later Steven Lukes (1968), would argue that methodological individualism was actually just an oblique way of asserting a commitment to metaphysical or ontological individualism. In other words, Popper’s “methodological individualism” was actually a claim about what the world “really” consisted of, little more than a fancy way of saying “there is no such thing as society.” Watkins went on to reinforce this impression by reformulating the thesis as the claim that the “ultimate constituents of the social world are individual people” (1957, 105).
