13 - The King Is Dead, Now What? The 250-Year Struggle for Democracy (Part 2)
In the The King Is Dead, Now What? we're exploring the history of the left / right political spectrum and the 250 year struggle for democracy. In Part 1 we started telling the story that began with the French Revolution of 1789, when those in favor of monarchy sat on the right wing of the national assembly room and those in favor of revolution sat on the left wing. In the wake of the 1848 revolutions, the struggle between left and right gave rise to three major political ideologies—conservatism, liberalism, and radicalism—each offering a distinct vision for society. These competing forces would ignite a global struggle for power. In this episode, we trace the ongoing clash between these ideologies, imagining them as bickering gods, each vying for control of the human realm. From the Russian Revolution and the collapse of monarchies after World War I to the rise of fascism, the global conflict of World War II, the Cold War standoff between the U.S. and Soviet Union, and the global youth protests of 1968, we explore how these powerful ideas collided, evolved, and continue to shape the struggle for power, equality, and freedom.

Astrophysics for a New Stone Age with Tom Murphy
What will happen to our scientific knowledge if civilization collapses? Will astrophysics survive a future stone age? In this episode, we rest from our journey to talk with astrophysicist Tom Murphy, who’s been on an odyssey of his own—moving from academia to a growing concern about the collapse of civilization, to an ever expanding appreciation of the cosmos. Together we’ll gaze at the grandeur of the stars and marvel at the complexity of one of our oldest cousins: the amoeba. If you’re seeking a moment to marvel at the interconnectedness of life on Earth and the universe its interwoven with, this is the episode for you. Tom Murphy is an Emeritus Professor of Physics and Astronomy/Astrophysics at the University of California, San Diego. After a career studying colliding galaxies and testing General Relativity using lasers to the moon, Murphy retired early to shift focus onto Planetary Limits and the intrinsic incompatibility between modernity and ecological longevity. Creator of a textbook on energy, the Do the Math blog, and the Metastatic Modernity video series, his main plea is that you bypass these resources and read the book Ishmael, by Daniel Quinn.

11 - Capitalism & Monopoly: Why The Best Board Games Make The Worst Reality
Looking for a game to play over the holidays? Why not try the real world global economy? Too late, you’re already playing it! Have you ever noticed how the most popular board games just so happen to reflect core components of our civilization? Settlers of Catan involves the extraction of raw materials. Risk is the imperialism and war between nations. Monopoly demonstrates the pitfalls of capitalism. Now in the real world, I rarely celebrate resource extraction, imperialism, or capitalism. But the board game versions are so much fun. Maybe that’s why we’re all playing it at a global level. As horrible as the side effects of these things are, enough people are having so much fun playing. And not just those winning. Sure, winning is awesome. But don’t count out how much fun it is to be down just enough to think if you keep trying you can get back in it. Your competitiveness takes over and you can’t put the game down. And then for even more people, they have no choice in the matter, they have to play, even though there’s no hope for winning, they’re just trying to survive and stay in the game. At this point, most of the world has been roped into this game of conquering, exploitation, and finance. We’re so convinced this is just normal life, most people don’t even think they’re playing a game. But unlike most board games, it doesn't come with an instruction manual. That is… until now. In this episode, we use sociologist Immanuel Wallerstein’s seminal text, World-Systems Analysis, as our instruction manual to the game of colonization and exploitation. We explore how dominant countries rise and fall, the dance between capitalism and the state, and the unexpected truth about what real power looks like. Join us for a deep dive into empires, markets, mafias, and everyone’s favorite Monopoly piece: the thimble. Macro-economics has never been this entertaining and fun for the whole family.

9 - Out of Society and Into the Wild: The Legend of Christopher McCandless
In the spring of 1992, twenty-four-year-old Christopher McCandless left society behind, hitchhiking 3,000 miles into the Alaskan wilderness. Two years earlier, Chris had donated his entire life savings to Oxfam, burned his social security card, and headed west seeking life on his own terms - without telling a soul, particularly his parents. In this episode, we delve into Into the Wild's larger cultural implications, exploring the conflict between self and society, community and solitude. Philosophers like Henry David Thoreau, John Muir, and John Locke will weigh in. As well as George Carlin and Malcolm and the Middle. We’ll investigate the concept of “wilderness” - how Euro-American settlers viewed it versus their Native American counterparts. And for those of us who dream of escaping the troubles of society, we’ll explore McCandless as an inspiration and cautionary tale.

Can We Escape Modern Civilization? A Conversation with the Hosts of Crazy Town
Is it possible to escape industrialism, capitalism, imperialism or are we trapped?

Death in the Regenerative Garden: Rethinking Food, Farming, and the Cycle of Life
What death is required for life to grow? In our culture’s resistance to death we seem to have caused so much of it. And what if humans aren't inherently a destructive force on the planet? How might we actually be another symbiotic part of our ecosystems?

Mandy Magill is a regenerative agriculture educator and cofounder of the Earth Regeneration Alliance. In this episode we’re sharing exerpts from both these conversations to explore our culture’s aversion to death, how food is the nexus of civilization, and alternatives to conventional farming that can regenerate ecosystems and recreate our relationship with nature.
