A former science and technology editor for The Economist magazine, Matt Ridley is a journalist and best-selling author whose books include Genome: The Autobiography of a Species in 23 Chapters. His most recent book is The Rational Optimist: How Prosperity Evolves.
Matt Ridley discusses the evolutionary process of "ideas having sex," calling it the secret behind human progress. He asserts that "barter was the trick that changed the world" and outlines his argument that life for the average human being is richer, healthier, and kinder than ever. Finally, he discusses whether limited government and rational optimism go hand in hand.
