How the Moon shaped humanity — and defined life on Earth

From the earliest days of cinema to our era of streaming, zooming, and scrolling, the screen has become a central part of our lives -- so central that it actually impedes our lives, erasing our bodies, and to hiding from one another. Kim Nelson, film professor and director of the Humanities Research Centre at the University of Windsor, argues in a public talk that remaining connected entails protecting and treasuring the enduring wisdom of the humanities -- literature, history, philosophy, art, and drama. This event was held at the University of Windsor and features an onstage interview between Kim Nelson and IDEAS host Nahlah Ayed.

For more than a thousand years the Oracle of Delphi sat on a stool at the ‘navel of the universe.’ Under a mystical trance, she would offer cryptic predictions of the future. People would wait months, even years, for their chance to ask the Oracle for guidance on matters ranging from reproductive challenges, to family tiffs to when and how to wage war.While the ritual around her remains shrouded in mystery, her predictions were – strangely – always right. Today our urge to predict the future mirrors the same psychological need that drove leaders to the Oracle at Delphi -- discomfort with uncertainty and deep seeded desire to control the unpredictable.

More than 2,000 years ago, someone sat down and wrote a travel bucket list for the ancient world — suggesting must-see places that we now call The Seven Wonders of the World. It was kind of a Lonely Planet guide of its time, and included the Pyramid of Giza, the Hanging Gardens of Babylon, the lighthouse of Alexandria, and the Temple of Artemis, among others. Historian Bettany Hughes brings monuments and archaeological discoveries back to life in her book,"The Seven Wonders of the Ancient World." *This episode originally aired on Nov. 6, 2024.

For the first two billion years, the Earth didn't have oxygen. That's just one of the many fascinating details Peter Frankopan reveals in his book, "Earth Transformed: An Untold History." The Oxford professor of global history takes us on a multi-million year tour, illustrating the breathtaking ways climate has shaped the Earth and human civilization. How the collapse of a sediment shelf 8,000 years ago isolated what's now Britain from Europe, and its potential influence on the Brexit vote in 2016. Or how climate fluctuations correlate to periods of antisemitic violence. There's a lot to learn in this podcast. Have a listen. *This episode originally aired on Feb. 9, 2026.

Authors Naomi Klein and Astra Taylor want to stop apocalyptic end-of-the-world thinking and its fantasies about colonizing other planets. “We love it here… we want to stay,” they say. They diagnose today's fascism as having an “Armageddon Industrial Complex,” whose main agents are apocalyptic fundamentalists, ethnonationalists, and tech billionaires fixated on creating a super-intelligence at any cost. In their book “End Times Fascism and the Fight for a Living World,” Klein and Taylor explore the convergent forces which not only welcome the end of the world, but seek to accelerate it.Guests in this podcast:Naomi Klein Naomi Klein is the author of several books including "No Logo" and "The Shock Doctrine," and "Doppelganger" which have sold in the millions around the world.

She is also a professor of Climate Justice at the University of British Columbia.Astra Taylor delivered the 2023 CBC Massey Lectures, called "The Age of Insecurity: Coming Together as Things Fall Apart."

If you ask security expert and author Patrick Lennox the answer is a resounding ‘yes.’ He argues Alberta separatism is less about Western alienation and more about a global effort to destroy liberal democracy. In his book, On Treason, Lennox says what’s unfolding in Alberta is part of a nefarious — and treasonous playbook that’s been used worldwide. To survive the threat, he suggests Canada must call out the traitors and arm ourselves against disinformation and deceit. *This is the final episode in our three-part series asking: what makes a nation?Listen to other episodes in this series:Map of CascadiaQuebec Separatism for NewcomersGuest in this podcast:Patrick Lennox is an international relations scholar and worked as a security expert for the Canadian government.

There’s a place where people make hoppy beer, fresh sushi, and damn fine coffee. It's called Cascadia. The lifestyle is laid-back, the scenery is majestic, and they even have a flag. Where is it exactly? Think of it as an ecological region stretching from Alaska to B.C. through the Pacific Northwest to Northern California. Its national identity transcends borders, and is bound through culture, history, attitude and language.

Bureaucracies were created to get the work done and get it done efficiently, according to 19th-century thinker Max Weber.
