One can understand well enough how human beings may struggle and murder for good material reasons - reasons connected, for instance, with their physical survival. It is much harder to grasp how they may come to do so in the name of something as apparently abstract as ideas. Yet ideas are what men and women live by, and will occasionally die for.

From the viewpoint of political power, culture is absolutely vital. So vital, indeed, that power cannot operate without it. It is culture, in the sense of the everyday habits and beliefs of a people, which beds power down, makes it appear natural and inevitable, turns it into spontaneous reflex and response.
