[C]onfessional memoirs have been irresistible to both writers and readers for a very long time, and, pretty much from the beginning, people have been complaining about the shallowness, the opportunism, the lying, the betrayals, the narcissism. This raises the question of just why the current spate of autobiography feels somehow different, somehow “worse” than ever before—more narcissistic and more disturbing in its implications. And it may well be that the answer lies not with the genre—which has, in fact, remained fairly consistent in its aims and its structure for the past millennium and a half or so—but with something that has shifted, profoundly, in the way we think about our selves and our relation to the world around us.
