• Introduction; 1. The meaning of 'security'; 2. What is worth securing, and why?; 3. Ecospheric security; 4. State security; 5. Cultural security; 6. Human security; Conclusion.

'This book offers a masterclass in understanding the meanings and implications of the concept of security, taking the reader on a deep intellectual journey into the underpinnings of this fundamental concern. Welch converses with the reader as he challenges convention and forces us to reconsider what it means to be 'secure' and therefore how to assess and understand insecurity. Beautifully written, the movement between philosophical and theoretical discussion and carefully rendered empirical materials provides the reader with remarkable insight into this most basic concept in both the scholarship and praxis of world politics.'
