A biography of Alcoholics Anonymous founder Bill Wilson leaves Daniel Asa Rose distrustful of biographer Susan Cheever. “Can a biographer be said to have so much understanding that she overidentifies with her subject? Is the biographer’s function to plead her subject’s case (“he was not a perfect man, but he was the perfect man for the job,” his “humanness does not diminish him, it makes him a writer, guide, and teacher,” etc.), or to let the unvarnished facts speak for themselves? When does discretion become a veil? Is there such a thing, in a biographer, as too much heart?”
