Nothing personal.

As an artist, Avedon told the truth about lies, and why we need them or metaphors to survive, and how people fit into their self-
mythologizing like body bags, and die in them if they’re not careful. Look at his portrait of Marilyn Monroe in “Nothing Personal,” perhaps one of the most difficult pictures in the book. In an interview, Dick said Monroe had given a performance as Marilyn Monroe earlier in the shoot, laughing and giggling and dancing. But then the shoot was over, and where was she? Who was she? “Nothing Personal” is riddled with these questions of identity—what makes a self?—a question that gave a certain thirteen-year-old ideas about the questions he might ask in this world: Who are we? To each other? And why? If Avedon’s 1959 book, “Observations” (with text by Truman Capote), was, by and large, about the certainty of the self and that self’s show-business finish or fake but felt truthfulness, Avedon’s work in “Nothing Personal” was about the breakdown of that certainty; indeed, it was about the breakdown of the social structure Americans like Avedon had grown up in along with all those borrowed dogs. “Nothing Personal” was his chance to move beyond what he had made his name as—a fashion photographer, a theatre portraitist—and to show what he didn’t know but felt.
