"This book provides a rich and timely philosophical reflection on how thinkers from antiquity onwards have grappled with the nature of information, in its various forms, and with its socio-political consequences. In the midst of an information revolution, where new technology is transforming society in ways we have yet to grasp, it is urgent that we study the epistemic and ethical consequences of how information is stored and spread. This volume is the place to start." Åsa Wikforss, Stockholm University and The Swedish Academy
