Ethnomethodology is in trouble, its conceptual apparatus prone to indifference or misunderstanding both from "conventional" sociologists and from its own practitioners. This article describes some of these loci of confusion and suggests that they have a common root in the relationship between ethnomethodology and conventional sociology. Ethnomethodologists' desire to find a principled theoretical framework for dealing with this relationship is shown to be the common basis for subsequent confusion, and some of the corollaries of their putative solution(s) are elaborated with (...) regard to their philosophical and programmatic implications. Key Words: ethnomethodology • social constructionism • situated action • social structures. (shrink)
