???Ridley writes with panache, wit, and humor and displays remarkable ingenuity in finding ways to present complicated materials for the lay reader.??? ??? Los Angeles Times In a bold and provocative interpretation of economic history, Matt Ridley, the New York Times-bestselling author of Genome and The Red Queen, makes the case for an economics of hope, arguing that the benefits of commerce, technology, innovation, and change???what Ridley calls cultural evolution???will inevitably increase human prosperity. Fans of the works of Jared Diamond (Guns, Germs, and Steel), Niall Ferguson (The Ascent of Money), and Thomas Friedman (The World Is Flat) will find much to ponder and enjoy in The Rational Optimist.
