   Beyond the critique of functional explanations, Elster does not advance any original argument in support of methodological individualism. He does, however, return to the earlier Weberian formulation of the position, with its emphasis on intentional action (Elster 1982, 463): “The elementary unit of social life is the individual human action,” he argues. “To explain social institutions and social change is to show how they arise as the result of the actions and interaction of individuals. This view, often referred to as methodological individualism, is in my view trivially true” (Elster, 1989, 13). Here one must assume that when he says “trivially true,” he is using the term in the vernacular sense of “platitudinous” rather than the philosophical sense of “tautologous,” since he goes on to derive a number of very substantive doctrines from his commitment to methodological individualism. For example, he goes on to claim at various points that methodological individualism commits him to psychologistic reductionism with respect to sociology (although he does not offer an argument for this claim).
