This penetrating book raises questions about how power operates in contemporary society. It explains how the speed of information flows has eroded the separate space needed for critical reflection. It argues that there is no longer an 'outside' to the global flows of communication and that the critique of information must take place within the information itself. The operative unit of the information society is the idea. With the demise of depth reflection, reflexivity through the idea now operates external to the subject in its circulation through networks of humans and intelligent machines. It is these ideas that make the critique of information possible. This book is a major testament to the prospects of culture, politics and theory in the global information society.
