Unproven but common understandings about the nature of reality develop, and these allow for daily discourse and social cohesion. The problems in Bosnia, for example, are fundamentally connected to the inability of its citizens to share some version of reality. In short, no culture, no society. They therefore must be important politically. For several reasons the subject is daunting, and this may account for the lack of attention to it.
Cultures are pervasive and evolving.
They cannot be described fully. There is no way to account for all of the cultural nuances relevant to an understanding of American political life, and nowhere to stand to see our culture wholly and clearly. Simultaneously, and ironically, culture is something that, by definition, we are all experts in. Because cultures bind members of a group, their characteristics must be palpable to them. Those who treasure the throne of expertise would be wise to look elsewhere for a subject.
