16 - How To Survive A Zombie Apocalypse
A horrific zombie apocalypse has ravaged the world—but hardly anyone seems to notice. One lone podcast sets out to interview those navigating this strange new reality: from people attending mindful zombie retreats and binging zombie media, to those stockpiling shotguns and fortifying bunkers, to others disappearing into the woods to build something entirely new.

Andor, Star Wars, Rebellion, and the Reality of Our Global Empire
This is the first 30 minutes of a longer conversation. The full conversation is available on the Human Nature Odyssey Patreon. === A long time ago, in a galaxy far, far away, there was an old Republic that, out of fear of a phantom menace, voted to consolidate authoritarian power—unknowingly sealing its own demise. It transformed into an Empire, bent on wielding its weapons of mass destruction to conquer all who dared resist. But don't worry—this is just a story. It has nothing to do with us. After all, it all happened a long time ago in a galaxy far, far away. Right? Jake Marquez and Maren Morgan are fellow podcasters, filmmakers, and friends. We continue our mid-month bonus series where we take something from the zeitgeist and view it through a broader civilizational lens.

15 - Are Hunter-Gatherers Liberals or Conservatives?
What insights can our ancient past shine on our political future? Were hunter-gatherers the ultimate traditionalists—or proto-communists? Is it possible hunter-gatherers lived with greater equality and more political freedom than most societies today? And why do both communism and capitalism, despite being sworn enemies, rest on the same assumption of endless growth? Psychologist Jonathan Haidt argues that humans are wired with both liberal and conservative tendencies—and that societies function best when those forces stay in balance. Where can we find the liberal and conservative elements in our hunter-gatherer past? And how might it reframe our political future? In The King Is Dead, Now What? we explored modern political history. Now we zoom out, connecting the dots to a much broader civilizational story. Plus, we're debuting a new segment: The State of Civilization, featuring our up-and-coming optimistic reporter Jeff Opolis, reporting on the fantastic news coming from civilization right now.

And On The Eighth Day God Created AI
This is the first 30 minutes of a longer conversation. The full conversation is available on the Human Nature Odyssey Patreon. === Jake Marquez and Maren Morgan are fellow podcasters, filmmakers, and new friends. Starting today, the three of us are joining forces to create monthly bonus episodes where we'll seek to better understanding this self-destructive civilizational 10,000 year predicament we find ourselves in. In this episode we discuss artificial intelligence. We found that despite all our philosophical overlap we were advocating two different approaches when it came to AI. I was exploring the idea of a cautious adoption, Maren argued for more of an abstinence policy. I've said it before and I'll say it again, every good conversation ends with the same conclusion: oh yeah, balance. We find ourselves there eventually. But the road we take is filled with insights, questions, and jokes.

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.
