Book excerpt: This volume presents a comprehensive analysis of global future scenarios and their impact on a growing, shared culture. Ever since the end of the Cold War, a diverse range of future concepts has emerged in various areas of academia—and even in popular journalism. A number of these key concepts—‘the end of history,’ ‘the clash of civilizations,’ ‘the coming anarchy,’ ‘the world is flat,’ ‘soft power,’ ‘the post-American century’—suggest what could become characteristic of this new, interconnected world. Ulf Hannerz scrutinizes these ideas, considers their legacy, and suggests further dialogue between authors of the ‘American scenario’ and commentators elsewhere.
