George Makari at Literary Hub:
George Makari: I heard you say in an interview that as you’re starting to think about writing a book, you write a note to yourself, saying, “Write a book that no one else could write.”
Geoff Dyer: Yeah, it’s a little piece of self-encouragement. Because, you know, sometimes I’m sort of worried about my take on a given subject. Do I know enough about it? Take for example, my history of photography called The Ongoing Moment. I wrote that book because I wanted to find out about the history of photography. I wrote the book for the same reason that readers might later go to it.
I think one of the features of nonfiction today is that, to a degree, a book could be written by anyone possessed of a certain level of knowledge. The area of expertise might change, but quite often, there’s nothing particularly distinct about the writing or the thought. With my books, for good or ill, they could only be written by me.
