Revisiting the structure/agency debate, the article puts forward the broad position shared by Giddens’structuration theory and Bhaskar's transformational model. It defends Giddens’concept of structure as‘rules and resources’against charges of idealism, arguing that its strength is its focus on the interface of structure and agency. But both Giddens and Bhaskar emphasise social reproduction as an unintended consequence of social action. Taking issue with postmodern pessimism, the article goes on to consider the conditions of possibility, and requisite forms of knowledgeability, for deliberate (...) social transformation. (shrink)
