Ron and Ed are honored to welcome Virginia Postrel, author of The Fabric of Civilization: How Textiles Made the World. Virginia is also a columnist and speaker whose work spans a broad range of topics, from social science to fashion, concentrating on the intersection of culture, commerce, and technology. Writing in Vanity Fair, Sam Tanenhaus described her as a master D.J. who sequences the latest riffs from the hard sciences, the social sciences, business, and technology, to name only a few sources.
