OF

I have a friend in cultural geography. Whenever he talks about some project in his field, whether his or a colleague's or grad student's, he almost always uses the preposition "of." "The Geography of _____ " There is nothing wrong with that, but it is the equivalent of the anxiety in Cultural studies. Each field has its givens that are hard to see from inside. I don't even know what mine are though I have been trying to figure it out in the past few months.
