Abstract
The debate about Habermas' use of the system and lifeworld distinction has not focused on the explanation of social pathologies that he offers, but rather only on conceptual problems with the theories that he uses. Twill argue that the explanation offered by his thesis that "systems colonize the lifeworld" fits the main criterion for adequacy for macro-micro explanation: because it establishes macro-micro linkage, it is at least potentially complete. Such an analysis fits the empirical approach to traditional debates between collectivists and individualists among macrosociologists. I shall apply this approach here in three steps. First, I shall use the controversy about functionalist explanation in the social sciences to develop the criterion of completeness for macrosociological explanations (1). Second, I shall generalize the conditions of adequacy for functionalist explanations to macrosociology as a whole and show that Habermas'explanation of the colonization of the lifeworld is at least potentially complete, as an explanation sketch that lacks empirical detail (2). Third, I shall show that this approach also requires that Habermas modify his overly Weberian claims about the effects of bureaucracy, since his stronger notion of reification is based on the incompletness in his explanation of this aspect of the micromacrolinkage (3). Moreover; a more complete account has clearer practical consequences for agency in the form of collective action.
