Book excerpt: Engaging with several emerging and interconnected approaches in the social sciences, including pragmatism, system theory, processual thinking and relational thinking, this book leverages John Dewey and Arthur Bentley’s often misunderstood concept of trans-action to revisit and redefine our perceptions of social relations and social life. The contributors gathered here use trans-action in a more specific sense, showing why and how social scientists and philosophers might use the concept to better understand our social life and social problems. As the first collective sociological attempt to apply the concept of trans-action to contemporary social issues, this volume is a key reference for the growing audience of relational and processual thinkers in the social sciences and beyond.
