Action and Interaction is divided into three parts. The first part focuses on the nature of action, starting with questions about action individuation, context, the notion of ?basic action? and the temporal structure of action. The importance of circumstance for understanding action is stressed. These topics lead to questions about intention and the sense of agency and ultimately to the idea that we need to consider action in the social contexts of interaction. The second part looks at the role of interaction in discussions of social cognition, building a contrast between standard theory- of-mind approaches and embodied/enactive accounts. Gallagher defends an enactive-interactionist account drawing on evidence from both phenomenology and empirical studies of development, ecological psychology, and studies of communicative and narrative practices, especially in more complex social practices. The third part transitions from considerations that focus on social-cognitive issues to understanding their implications for concepts that are basic to the development of a critical theory that addresses social and political issues, especially with respect to basic concepts of autonomy, recognition and justice, and the effects of norms and social institutions on our actions and interactions
