13. Taking Stock of Integration Theory
This volume has examined the state of the art in European integration theorizing with chapters which have presented and reflected upon the core theoretical contributions that have been developed since the early stages of studying European integration and governance. This concluding chapter provides a historical overview of the type and focus of each theoretical approach to European integration. It compares the respective strengths and weaknesses of each approach according to the definitions of ‘theorizing’ and ‘integration’ developed in the introduction. It also considers the first edition’s outlook on constitutional development and identifies current challenges that lie ahead. It argues that the different theoretical perspectives discussed in this edition demonstrate an emerging robustness of European integration theory. It suggests that the variation in approaching the respective ‘test cases’ of European enlargement reveals the need for both rigorously prescriptive and normative approaches to European integration.
