This book is grounded in political philosophies, which underpin theories of European integration. The book argues that the reason states are prepared to involve themselves in the EU project can be explained through the Kantian civil constitution and Hegelian recognition. These concepts inform European integration theories and provide the basis for the paradoxical nature of the EU in terms of unity and diversity. Indeed, Europeanization deals with these paradoxes in terms of up-loading, downloading and its relationship with European integration theory. The text develops an understanding of Europeanization based on downloading and up-loading. Downloading is the means by which EU policy is combined with domestic legislation and institutions. Up-loading indicates the use of national governments or sub-national interests in the development of European integration processes. European integration takes place at the supranational level and in general, is distinct from Europeanization. Through a study of financial services regulation these processes are made explicit.
