This book presents post-praxeology, an approach that brings process philosophy and ethnomethodology together to study social life as ongoing processes. Rather than explaining action through individuals or structures alone, it examines how heterogeneous elements come together within concrete situations. Brian L. Due develops post-praxeology as a way of studying process-in-practice grounded in process ontology and operationalised through ethnographic methods. The result is both a conceptual orientation and a methodological toolkit for analysing social phenomena as continuously unfolding formations.
