“One day the day will come when the day will not come.” Bleak, but passionately political in its analysis of the social destruction wrought by modern technologies of communication and surveillance, <i>Open Sky</i> is Paul Virilio’s most far-reaching and radical book. Deepening and extending his earlier work, he explores the growing danger of what he calls a “generalized accident,” provoked by the breakdown of our collective and individual relation to time, space and movement in the context of global electronic media. But this is not merely a lucid and disturbing lament for the loss of real geographical spaces, distance, intimacy or democracy. <i>Open Sky</i> is also a call for revolt—against the insidious and accelerating manipulation of perception by the electronic media and repressive political power, against the tyranny of “real time,” and against the infantilism of cyberhype. Virilio makes a powerful case for a new ethics of perception, and a new ecology, one which will not only strive to protect the natural world from pollution and destruction, but will also combat the devastation of urban communities by proliferating technologies of control and virtuality.
