Even though September 11 hovers over this mesmerizing look into the nature of eventsit was the fall of the Twin Towers that inspired Robin Wagner-Pacifici initiallythe richly evocative and thoughtful story she tells scales up to the level of major historical events and it scales down to the micro-level of ruptures in individual lives. Wagner-Pacifici moves back and forth between events experienced with all their vivid, pulsating, and demanding realities, and events understood systematically and conceptually. It is an astonishing achievement: a book that works with events, and a book that builds a model for analyzing them. She makes contact with specific eventful ruptures and turning-points; she analyzes how events erupt and take off from the ground of ongoing, everyday life, and how they move across time and landscapes. What Is an Event gives us a crystalline condensation of idea, image, analysis, and act, teasing out multiple possibilities for conceiving of events in series, in ruptures, in causal mechanisms, in short and long duration, and in their reception by the public. Wagner-Pacifici peppers each chapter with brilliant, vivifying examples: from 9/11 (four air hijackings, with multiple target sites, propelling the event from rupture, to accident, to incident, to attack, to war in rapid fashion, and on to the trial of Khalid Sheikh Mohammed and the memorial museum at ground zero, and so much else) to the shooting in Camus s The Stranger to the shooting of Trayvon Martin. There is much in between. These examples take on the form of exemplars, models, paradigms. They show the productive pathways that keep events alive and coherent, and uncover the mechanisms by which forces and agents attempt to shape and move events. This book changes the conversation about how history is made."
