Developing a comprehensive framework for understanding these dangers and for planning a more cosmopolitan future, this book offers a radical and original theory of security for our times.What is real? What can we know? How might we act? This book sets out to answer these fundamental philosophical questions in a radical and original theory of security for our times. Arguing that the concept of security in world politics has long been imprisoned by conservative thinking, Ken Booth explores security as a precious instrumental value which gives individuals and groups the opportunity to pursue the invention of humanity rather than live determined and diminished lives. Booth suggests that human society globally is facing a set of converging historical crises.
