Manuel Castells highly-acclaimed trilogy, The Information Age, represents the most comprehensive attempt to develop a coherent social theory of the present day. From his early, groundbreaking work on urban change and social movements, to his current work on the social transformations in a globalized
world based on the use of new communication technologies, Castells has been at the forefront of contemporary debates for over three decades. At the heart of his theory lies the claim that we are witnessing a shift from vertically-integrated hierarchies to flexible, distributed networks which structure dominant social processes as well as the main challenges launched
against them. His scope, rigor and style have earned him favorable comparison with the great classics of sociology, particularly Max Weber. This book provides the first complete study of Castells theory of the network society. It is a critical examination of his analysis of informational
capitalism', of global social movements as the source of new values, and of networked governance. Felix Stalder also provides an original and in-depth
account of the theory of the space of flows and of Castells particular notion of the character of informational networks. The book serves as both an
excellent introduction to Castells wide-ranging theories and an innovative critique which contributes to ongoing debates in the field.
