Co-published with the Weatherhead Center for International Affairs, this book offers a critical assessment of European Union developments since 1994. It combines the texts of the five Paul-Henri Spaak lectures given at Harvard University in the 1994-2000 period, and a cogent analysis of the successes and failures of the EU by Professor Andrew Moravcsik, entitled "Europe without Illusions." The European Union is the most successful voluntary international organization in world history. Europe without Illusions explores the paradox that the EU recently completed perhaps the most successful decade of integration in its history, yet it continues to be widely perceived as unstable and undemocratic. The Center for International Affairs was founded in 1958 and was renamed the Weatherhead Center for International Affairs in 1998 in gratitude for the endowment established by Albert and Celia Weatherhead and the Weatherhead Foundation. The Center was created as a means of confronting global problems. The Center is the largest international research center within Harvard University's Faculty of Arts and Sciences. It is distinctive in its recognition that knowledge is a product not only of individual academic research, but also of vigorous, sustained intellectual dialogue among scholars and nonacademic experts. To stimulate this dialogue, the Center sponsors a wide array of seminars, research programs, workshops, and conferences.
