From its publication amid the social upheavals of the 1960s up to the present, the volatile theses of this book have decisively transformed debates on the shape of modernity, capitalism and everyday life in the late twentieth century. Now finally available in a superb English translation approved by the author, Debord's text remains as crucial as ever for understanding the contemporary effects of power, which are increasingly inseparable from the new virtual worlds of our rapidly changing image/information culture.
