    It is a brilliant and elegant exercise in model building that provides new insights into some of the old questions about philosophy of history, historical narrative, and what is called straight history."-Hayden White, University of California, Santa CruzWho were the first people to inhabit North America? Does the West Bank belong to the Arabs or the Jews? Why are racists so obsessed with origins? Is a seventh cousin still a cousin? Why do some societies name their children after dead ancestors?As Eviatar Zerubavel demonstrates in Time Maps, we cannot answer burning questions such as these without a deeper understanding of how we envision the past. In a pioneering attempt to map the structure of our collective memory, Zerubavel considers the cognitive patterns we use to organize the past in our minds and the mental strategies that help us string together unrelated events into coherent and meaningful narratives, as well as the social grammar of battles over conflicting interpretations of history. Drawing on fascinating examples that range from Hiroshima to the Holocaust, from Columbus to Lucy, and from ancient Egypt to the former Yugoslavia, Zerubavel shows how we construct historical origins; how we tie discontinuous events together into stories; how we link families and entire nations through genealogies; and how we separate distinct historical periods from one another through watersheds, such as the invention of fire or the fall of the Berlin Wall.Most people think the Roman Empire ended in 476, even though it lasted another 977 years in Byzantium. Challenging such conventional wisdom, Time Maps will be must reading for anyone interested in how the history of our world takes shape.

    Reviews of new games and profiles of game designers now regularly appear in the New York Times and the New Yorker, and sales figures for games are reported alongside those of books, music, and movies. They are increasingly used for purposes other than entertainment, yet debates about videogames still fork along one of two paths: accusations of debasement through violence and isolation or defensive paeans to their potential as serious cultural works. In How to Do Things with Videogames, Ian Bogost contends that such generalizations obscure the limitless possibilities offered by the medium’s ability to create complex simulated realities.Bogost, a leading scholar of videogames and an award-winning game designer, explores the many ways computer games are used today: documenting important historical and cultural events; educating both children and adults; promoting commercial products; and serving as platforms for art, pornography, exercise, relaxation, pranks, and politics. Examining these applications in a series of short, inviting, and provocative essays, he argues that together they make the medium broader, richer, and more relevant to a wider audience.Bogost concludes that as videogames become ever more enmeshed with contemporary life, the idea of gamers as social identities will become obsolete, giving rise to gaming by the masses. But until games are understood to have valid applications across the cultural spectrum, their true potential will remain unrealized. How to Do Things with Videogames offers a fresh starting point to more fully consider games’ progress today and promise for the future.
