Your co-hosts chat about hyperloops, hydrarails and that time Newt Gingrich flirted with Cymene. Then (16:54) renowned sociologist Saskia Sassen joins us to share her thinking about our contemporary environmental predicament. We talk about finance as the steam engine of our era, the reasons for its recent rise, and whether Saskia feels that finance can contribute to reversing environmental degradation. We then turn to her most recent book Expulsions: Brutality and Complexity in the Global Economy (Harvard UP, 2014), in particular to her discussion of the impacts of mining, and explore her argument that we need new concepts to replace the American-centric categories of mid 20th century social science. Saskia shares her thoughts on the Anthropocene and the Chthulucene and why she is interested in the problem of the “systemic edge” where our categories of analysis cease to capture the intensity of contemporary social and environmental conditions. We turn from there to the current crises of liberalism, water, and immigration and Saskia explains why she thinks that political classes across the world seem so checked out now. She details the unremarkable instruments that have scaled to produce planet-wide environmental destruction and asks whether it’s possible to imagine equally simple instruments for doing good in the world, perhaps by thinking and acting more like the biosphere itself. Finally we return to one of Saskia’s favorite topics—cities—and how urban space contains our future frontiers of politics and life. What are the ethics of the city? What’s it like to walk the city with Saskia Sassen? Listen on and find out!
