This book offers a range of perspectives on European integration from different scientific disciplines. It aims to give its readers the opportunity to look at European integration from various scientific angles, such as history, political science, philosophy of science, economics, legal theory, social ontology, and evolutionary psychology. By bringing together these disciplines, European Integration: A Theme hopes to contribute to the education of scientists who are able to place topics like European integration in a wider context and consider it from numerous perspectives. European Integration: A Theme takes this approach because European integration is a topic that can be given content from these several angles and about which several scientific disciplines have something to say. Also – and more importantly – it takes this approach because in an increasingly globalized and complex world, it is important to educate scientists who are able to address these complexities from more than one perspective.
