A truly common culture is not one in which we all think alike, or in which we all believe that fairness is next to godliness, but one in which everyone is allowed to be in on the project of cooperatively shaping a common way of life.
The frontier between public and private shifts from time to time and culture to culture.
Ivory towers are as rare as bowling alleys in tribal cultures.
It is easy to see why a diversity of cultures should confront power with a problem. If culture is about plurality, power is about unity. How can it sell itself simultaneously to a whole range of life forms without being fatally diluted?
Men and women do not easily submit to a power that does not weave itself into the texture of their daily existence - one reason why culture remains so politically vital. Civilisation cannot get on with culture, and it cannot get on without it.
