Twenty-five years ago, Edward Said's Orientalism spawned a generation of scholarship on the denigrating and dangerous mirage of "the East" in the Western colonial mind. But "the West" is the more dangerous mirage of our own time, Ian Buruma and Avishai Margalit argue, and the idea of "the West" in the minds of its self-proclaimed enemies remains largely unexamined and woefully misunderstood. Occidentalism is their groundbreaking investigation of the demonizing fantasies and stereotypes about the Western world that fuel such hatred in the hearts of others. We generally understand "radical Islam" as a purely Islamic phenomenon, but Buruma and Margalit show that while the Islamic part of radical Islam certainly is, the radical part owes a primary debt of inheritance to the West. Whatever else they are, al Qaeda and its ilk are revolutionary anti-Western political movements, and Buruma and Margalit show us that the bogeyman of the West who stalks their thinking is the same one who has haunted the thoughts of many other revolutionary groups, going back to the early nineteenth century. A work of extraordinary range and erudition, 'Occidentalism' will permanently enlarge our collective frame of vision.
