In a review of two new biographies about Ayn Rand, Charles Murray explains what made her books – particularly Atlas Shrugged – so powerful and persuasive:
In 1991, the book-of-the-month club conducted a survey asking people what book had most influenced their lives. The Bible ranked number one and Ayn Rand’s Atlas Shrugged was number two. In 1998, the Modern Library released two lists of the top 100 books of the 20th century. One was compiled from the votes of the Modern Library’s Board, consisting of luminaries such as Joyce Carol Oates, Maya Angelou, Edmund Morris, and Salman Rushdie. The two top-ranked books on the Board’s list were Ulysses and The Great Gatsby. The other list was based on more than 200,000 votes cast online by anyone who wanted to vote. The top two on that list were Atlas Shrugged (1957) and The Fountainhead (1943). The two novels have had six-figure annual sales for decades, running at a combined 300,000 copies annually during the past ten years. In 2009, Atlas Shrugged alone sold a record 500,000 copies and Rand’s four novels combined (the lesser two are We the Living  and Anthem ) sold more than 1,000,000 copies. And yet for 27 years after her death in 1982, we haven’t had a single scholarly biography of Ayn Rand. Who was this woman? How did she come to write such phenomenally influential novels? What are we to make of her legacy? These are the questions that finally have been asked and answered splendidly, with somewhat different emphases, in two new biographies published within weeks of each other: Goddess of the Market: Ayn Rand and the American Right by Jennifer Burns, an assistant professor of history at the University of Virginia, and Ayn Rand and the World She Made by Anne C. Heller, a former executive editor at Condé Nast Publications. …Why then has reading these biographies of a deeply flawed woman—putting it gently—made me want to go back and reread her novels yet again? The answer is that Rand was a hedgehog who got a few huge truths right, and expressed those truths in her fiction so powerfully that they continue to inspire each new generation. They have only a loose relationship with Objectivism as a philosophy (which was formally developed only after the novels were written). Are selfishness and greed cardinal virtues in Objectivism? Who cares? Does Objectivist aesthetics denigrate Bach and Mozart? Who cares? Objectivism has nothing to do with what mesmerizes people about The Fountainhead or Atlas Shrugged. What does mesmerize us? Fans of Ayn Rand will answer differently. Part of the popularity of the books derives from the many ways their themes can be refracted. Here is what I saw in Rand’s fictional world that shaped my views as an adolescent and still shapes them 50 years later.
