International Practice Theory is the definitive introduction to the practice turn in world politics, providing an accessible, up-to-date guide to the approaches, concepts, methodologies, and methods of the subject. It situates the study of practices in contemporary theory and reviews approaches ranging from Bourdieu's praxeology and communities of practice to actor-network theory and pragmatic sociology, documenting how they can be used to study international practices empirically. The book features a discussion of how scholars can navigate ontological challenges such as order and change, micro and macro, bodies and objects, and power and critique. Interpreting practice theory as a methodological orientation, it also provides an essential guide for the design, execution, and drafting of a praxiographic study.
