The new edition of What Do We Know about War? will be a great asset to students and scholars of international conflict. The chapters provide perceptive overviews of the current state of the discipline and in some cases even provide additional insights. This book is perfect for courses in international conflict and for scholars who want a good overview of an area of scholarship before beginning their own research.

The second edition of What Do We Know about War? is far more than just an update of the excellent first edition. The expansion of topics and consideration of new research not only masterfully answer the question the title asks but also give tremendous insight into both how the knowledge has been gained and where future work is likely to take us. The chapters offer great summaries of each facet of war's causes and consequences and will be tremendously useful in both undergraduate and graduate courses.

Douglas Lemke, Pennsylvania State University

By providing an excellent summary of scientific research findings on interstate wars during the past thirty-five or so years, this volume makes a valuable contribution.
