Why do civilizations rise and fall? What are the origins and purpose of art? How does technology shape society? Did culture direct human evolution? Is the Internet an agent of democracy or dictatorships? An immensely powerful but little-understood force that impacts society, art, politics, and even human biological development, culture is the very stage on which human experience plays out.
