The notion of social structure is intimately related to a variety of central topics in social science, including the relation of structure and agency. The most influential attempts to combine the concept of social structure with agency are Anthony Giddens' theory of structuration and Pierre Bourdieu's practice theory. Giddens emphasizes the duality of structure and agency, in the sense that structures and agency cannot be conceived apart from one another. This permits him to argue that structures are neither independent of actors nor determining of their behavior, but rather sets of rules and competencies on which actors draw, and which, in the aggregate, they reproduce. Giddens's analysis, in this respect, closely parallels Jacques Derrida's deconstruction of the binaries that underlie classic sociological and anthropological reasoning (notably the universalizing tendencies of Lévi-Strauss's structuralism). Bourdieu's practice theory also seeks a more subtle account of social structure as embedded in, rather than determinative of, individual behavior.
