Our world has always been one of walls, from the Great Wall of China to Hadrian’s Wall to the Berlin Wall. But now a new age of isolationism and economic nationalism is upon us, visible not just in Trump’s obsession with building a wall on the Mexico border or in Britain’s Brexit vote, but in many other places as well. And yet at the same time, large population movements are changing politics and culture as never before. What to make of these seemingly divergent trends? This discussion group will help us make sense of their impact on our national and global politics. First, Tim Marshall, in his book The Age of Walls (Scribner, 2018) will guide us through the maze of barriers, both physical and cultural, that continue to shape our world. Second, Robert P. Jones, in his book The End of White Christian America (Simon & Schuster, 2016), will tell us how changing demographics will forever alter the American political scene. We hope you will join us on this fascinating journey.
