Alexander L. George is a paragon of scholarship-an academic who successfully crosses boundaries between theory and policy, political science and several different disciplines, and case study analysis and theory building. Most of all, he bridges the gap between the ivory tower of research and the world of people, power, and politics. In these original essays, former students, colleagues, and admirers collaborate in portraying the research program of Alexander George’s scholarship in all its diversity and complexity, examining subjects ranging from the role of beliefs in foreign policy-making to the factors involved in diplomacy and the use of force. Taken together, these essays offer strong testimony to Alexander George’s extraordinary vision, erudition, and humanity.
