The book develops a novel approach to understanding social situations as emergent, empirical phenomena. It advocates a methodology that integrates insights from process philosophy (especially Whitehead and Deleuze) and non-anthropocentric perspectives with phenomenology and ethnomethodology. Introducing the framework of post-praxeology, the book expands upon traditional ethnomethodological praxeology by embracing process philosophy’s foundational concepts, such as flat ontology, distributed agency, and diverse assemblages comprising humans, nonhumans, and other material elements. The ‘post’ in post-praxeology signifies this shift beyond conventional praxeological concerns, presenting a comprehensive methodological stance that emphasises the emergent, situated nature of social phenomena without privileging any specific type of agent or material beforehand. The book promotes video ethnography as a principal methodological tool, uniquely enabling the detailed capture and analysis of ongoing, dynamic processes of becoming. It addresses scholars and researchers engaged in qualitative empirical research, providing a robust, innovative approach to exploring social situations across diverse empirical contexts.
