Is openness beneficial or harmful to societies, past and present? Swedish author Johan Norberg joins the show to discuss his book Open: The Story of Human Progress and talk about openness throughout history.  We discuss how open exchange, free movement, and openness to new cultures and new ideas have been key to building some of the biggest empires throughout history - and how those same values can benefit us today. Recommended reading - Karl Popper, The Open Society. Friedrich Hayek, The Constitution of Liberty.  Virginia Postrel, The Future and Its Enemies.   To make sure you hear every episode, join our Patreon at https://www.patreon.com/neoliberalproject.
