This work is a selection of essays discussing the idea of a evolutionary paradigm in international relations. The works span the spectrum of thought from those who reject the proposition to those you accept it and believe that it is the answer to the static nature of realist and liberal theory. The debate is wonderful and includes some of the greatest minds in international relations, sociology, and history. A truly interdisciplinary work.
If you are not interested in the idea of this paradigm, it is still a read because of the discussions on the use of the word evolution in modern thought. The word is being used in quite arbitrary ways to describe changes in the world. Attributing observations to evolution when it has nothing to do with it. This is an excellent work, but it is not a light read. This work does not require an exstensive knowledge of international relations so even if you don't know anything, you can pick this work up and understand what the authors are discussing. Highly recommended.
