“Ideally, a biography should penetrate into the subject’s psychology, and provide insight into the subject’s society and times; it should tell us what drives and fuels, what angers and scares, what pleases and pains the subject, and what makes him relevant and meaningful to the people and culture around him. Failing that, a biography should be a compelling and interesting narrative, employing fictional devices to render a subject knowable and human. Failing that, a biography ought to be sexy and scandalous, revealing shocking and disturbing details that show how perverted and perverting money, fame, and power really are. Failing that, it should be at least well-written. Failing all of these things, a biography should choose at the very least to be short.”
