The theory of structuration is a social theory of the creation and reproduction of social systems that is based in the analysis of both structure and agents (see structure and agency), without giving primacy to either. Further, in structuration theory, neither micro- nor macro-focused analysis alone is sufficient. The theory was proposed by sociologist Anthony Giddens, most significantly in The Constitution of Society, which examines phenomenology, hermeneutics, and social practices at the inseparable intersection of structures and agents. Its proponents have adopted and expanded this balanced position. Though the theory has received much criticism, it remains a pillar of contemporary sociological theory....the essential recursiveness of social life, as constituted in social practices: structure is both medium and outcome of reproduction of practices. Structure enters simultaneously into the constitution of the agent and social practices, and 'exists' in the generating moments of this constitution.:5When I utter a sentence I draw upon various syntactical rules (sedimented in my practical consciousness of the language) in order to do so. These structural features of the language are the medium whereby I generate the utterance. But in producing a syntactically correct utterance I simultaneously contribute to the reproduction of the language as a whole. ...The relation between moment and totality for social theory... a dialectic of presence and absence which ties the most minor or trivial forms of social action to structural properties of the overall society, and to the coalescence of institutions over long stretches of historical time.:24 The theory of structuration is a social theory of the creation and reproduction of social systems that is based in the analysis of both structure and agents (see structure and agency), without giving primacy to either.

Its proponents have adopted and expanded this balanced position. Though the theory has received much criticism, it remains a pillar of contemporary sociological theory. Sociologist Anthony Giddens adopted a post-empiricist frame for his theory, as he was concerned with the abstract characteristics of social relations. This leaves each level more accessible to analysis via the ontologies which constitute the human social experience: space and time ('and thus, in one sense, 'history'.'):3 His aim was to build a broad social theory which viewed 'he basic domain of study of the social sciences... neither the experience of the individual actor, nor the existence of any form of societal totality, but social practices ordered across space and time.':189 His focus on abstract ontology accompanied a general and purposeful neglect of epistemology or detailed research methodology. Giddens used concepts from objectivist and subjectivist social theories, discarding objectivism's focus on detached structures, which lacked regard for humanist elements and subjectivism's exclusive attention to individual or group agency without consideration for socio-structural context. He critically engaged classical nineteenth and early twentieth century social theorists such as Auguste Comte, Karl Marx, Max Weber, Émile Durkheim, Alfred Schutz, Robert K. Merton, Erving Goffman, and Jürgen Habermas. Thus, in many ways, structuration was 'an exercise in clarification of logical issues.':viii Structuration drew on other fields, as well: 'He also wanted to bring in from other disciplines novel aspects of ontology that he felt had been neglected by social theorists working in the domains that most interested him. Thus, for example, he enlisted the aid of geographers, historians and philosophers in bringing notions of time and space into the central heartlands of social theory.':16 Giddens hoped that a subject-wide 'coming together' might occur which would involve greater cross-disciplinary dialogue and cooperation, especially between anthropologists, social scientists and sociologists of all types, historians, geographers, and even novelists. Believing that 'literary style matters', he held that social scientists are communicators who share frames of meaning across cultural contexts through their work by utilising 'the same sources of description (mutual knowledge) as novelists or others who write fictional accounts of social life.':285 Structuration differs from its historical sources. Unlike structuralism it sees the reproduction of social systems not 'as a mechanical outcome, rather ... as an active constituting process, accomplished by, and consisting in, the doings of active subjects.':121 Unlike Althusser's concept of agents as 'bearers' of structures, structuration theory sees them as active participants. Unlike the philosophy of action and other forms of interpretative sociology, structuration focuses on structure rather than production exclusively. Unlike Saussure's production of an utterance, structuration sees language as a tool from which to view society, not as the constitution of society—parting with structural linguists such as Claude Lévi-Strauss and generative grammar theorists such as Noam Chomsky. Unlike post-structuralist theory, which put similar focus on the effects of time and space, structuration does not recognise only movement, change and transition. Unlike functionalism, in which structures and their virtual synonyms, 'systems', comprise organisations, structuration sees structures and systems as separate concepts. Unlike Marxism, structuration avoids an overly restrictive concept of 'society' and Marxism's reliance on a universal 'motor of history' (i.e. class conflict), its theories of societal 'adaptation', and its insistence on the working class as universal class and socialism as the ultimate form of modern society. Finally, 'structuration theory cannot be expected to furnish the moral guarantees that critical theorists sometimes purport to offer.':16 Giddens observed that in social analysis, the term structure referred generally to 'rules and resources' and more specifically to 'the structuring properties allowing the 'binding' of time-space in social systems'. These properties make it possible for similar social practices to exist across time and space and that lend them 'systemic' form.:17 Agents—groups or individuals—draw upon these structures to perform social actions through embedded memory, called memory traces. Memory traces are thus the vehicle through which social actions are carried out. Structure is also, however, the result of these social practices. Thus, Giddens conceives of the duality of structure as being: Giddens uses 'the duality of structure' (i.e. material/ideational, micro/macro) to emphasize structure's nature as both medium and outcome. Structures exist both internally within agents as memory traces that are the product of phenomenological and hermeneutic inheritance:27 and externally as the manifestation of social actions. Similarly, social structures contain agents and/or are the product of past actions of agents. Giddens holds this duality, alongside 'structure' and 'system,' in addition to the concept of recursiveness, as the core of structuration theory.:17 His theory has been adopted by those with structuralist inclinations, but who wish to situate such structures in human practice rather than to reify them as an ideal type or material property. (This is different, for example, from actor–network theory which appears to grant a certain autonomy to technical artifacts.) Social systems have patterns of social relation that change over time; the changing nature of space and time determines the interaction of social relations and therefore structure. Hitherto, social structures or models were either taken to be beyond the realm of human control—the positivistic approach—or posit that action creates them—the interpretivist approach. The duality of structure emphasizes that they are different sides to the same central question of how social order is created. Gregor McLennan suggested renaming this process 'the duality of structure and agency', since both aspects are involved in using and producing social actions.:322 The duality of structure is essentially a feedback–feedforward process whereby agents and structures mutually enact social systems, and social systems in turn become part of that duality. Structuration thus recognizes a social cycle. In examining social systems, structuration theory examines structure, modality, and interaction. The 'modality' (discussed below) of a structural system is the means by which structures are translated into actions.
