This is a genuinely groundbreaking book. It not only provides an introduction to the potential of Jacques Derrida for International Politics scholars and students, but is highly significant and lucidly written and will be sure to appeal to a wide audience.Dillon is an absolutely central figure here, internationally regarded for his contributions by political philosophers, international relations scholars and security studies experts, as well as by philosophers more broadly. It is difficult to over-rate his importance to the development of critical deconstructive approaches not only in challenging traditional scholarship and addressing contemporary politics, but in articulating new approaches and new thinking.This volume will provide an invaluable resource for teaching at undergraduate and postgraduate levels on traditional international relations courses and on the increasing number of specialised courses in critical approaches. It is well designed and structured to be accessible to the novice as well as challenging for the specialist, and will have a broad market.
