Historian Marci Shore doesn't hesitate to use the word 'fascism' to describe the present moment. The former Yale professor left the U.S. after President Trump was re-elected. She now teaches at the University of Toronto and tells her students why "we shouldn't fetishize" the term. Shore argues concepts and terminologies born from history like fascism is how we process the world, but it's critical we allow for today's nuances and differences.

This podcast includes Marci Shore in conversation with IDEAS host Nahlah Ayed and Shore's lecture “Thoughts From a Post Truth World," part of the series “Democracy in Peril: A Way Forward Against Authoritarianism," organized by the University of Manitoba, and the Canadian Museum for Human Rights in Winnipeg.

Marci Shore is Chair of European Intellectual History at the Munk School of Global Affairs & Public Policy at the University of Toronto.

Seabird biologist Bill Montevecchi has been ranked in the world’s top two per cent of scientists. Montevecchi died at the age of 80 in July 2026. In his honour, we share this 2023 documentary by producer Mary Lynk that shines a light on the renowned scientist's humanity and brilliance. Lynk followed Montevecchi on a wild two-day adventure in Newfoundland, climbing steep cliffs to spy on famous seabird colonies, and venturing on a heart-pounding overnight rescue mission of young storm petrels along the coastline.

After seizing power in a 1971 coup, Ugandan military commander Idi Amin promised a return to democracy — but he delivered a brutal dictatorship. Known for his erratic and sadistic behaviour, Amin’s reign was defined by ethnic purges, forced expulsions and total economic collapse. We continue our four-part series, How to Defeat Authoritarianism, exploring the legacy of Idi Amin and the conflation of personality with totalitarian politics.

What has become of the America that has for so long been held up as a shining example of ideals? In conversation at the 2026 Aspen Ideas Festival, documentary maker Ken Burns and American scholar and author Eddie Glaude unpack the vexed contradictions at the heart of American democracy, from the founding of the Republic in 1776 until today.

Behind every great chatbot are many human workers making decisions on how those chatbots behave and evolve. Recent PhD graduate Noah Khan has been observing these workers and shares his findings on their emotions and motivations as they design and build AI entities that communicate with users — influencing our own emotions and outlooks.

When Rohingya poet Mayyu Ali saw his name in print for the first time, he thought: "I exist." "Even though my government doesn't recognize [me] I exist in my writing," he told IDEAS.The Myanmar government has targeted the Rohingyas for decades, and Ali grew up with no birth certificate, no citizenship, and no human rights. He fled genocide in 2017 to live in a refugee camp in Bangladesh, until he resettled to Canada in 2021. Ali speaks with Nahlah Ayed about survival, the power of poetry, and his long journey to become a citizen for the first time in his life.

Fascism has been called “the aestheti-cization of politics.” Nazis and Italian Fascists both made visual culture, art, even fashion part of their destructive programs. Now the far-right in the U.S. is taking lessons from history, selling its ideas through memes, and hate-filled videos.

How do authoritarian leaders use threats, illusions and force to seize and maintain power? And what does it take for truth and justice to prevail? IDEAS explores the rise and fall of pivotal authoritarians and their regimes from recent world history, and asks what we can learn from their eventual downfall. We start our five-part series with the legacy of Italian fascism and its relevance today.

Acclaimed author Gabor Maté joins the conversation in part two of our series exploring Wilhelm von Humboldt’s public education system. Maté is a former English teacher. In this episode we ask: Is Humboldt's 200-year-old system equipped to meet the challenging demands of the 21st century? And does it still reflect his ideals, especially at the university level? *This episode concludes our two-part series. It originally aired on April 16, 2024.

Two hundred years ago, Wilhelm von Humboldt created the education system as we know it today. At the heart of his philosophy of education was the concept of Bildung — reaching one's inner potential. Yet over the years, as his public education system was adopted, Bildung may well have been the critical piece left out. *This episode is part one of two-part series.

Some parents like Dawn Quelch took a stand and banned it from their home. IDEAS examines the ideological roots of homework and the shift in thinking about child psychology and development.

What happens when original artworks become endless copies? German philosopher Walter Benjamin called it the death of "aura," and his concept predicted our digital age. He describes "aura" as the energy that encases an object, and argued standing before the presence of a great artwork was transcendent.

The world is feeling darker and darker these days. So this podcast might be a much-needed balm. It's about hope — a practice that scholar Shannon Murray argues can't be passive. That's where the German term 'freudenfreude' comes in, when someone celebrates the good fortune of others as if it's their own. Murray explains the power of freudenfreude and offers a guide to hope, empathy, and patience through the lens of Shakespeare. Yes. The Bard's words tie into all of this. *This episode originally aired on Nov. 13, 2023.

Throughout his career, it wasn't unusual for David Bowie to sing about death. But the musician used his own mortality as a theme for a final album that he released just two days before he died, on his 69th birthday.

Alain Deneault has a philosophical cure for eco-angst. He proposes turning the angst into actions in the face of unprecedented, unpredictable times. The most famous Acadian philosopher unknown to English-speaking Canadians suggests we brace for periods of severe crisis as nation-states and global networks become strained and fail. His prescription includes strengthening regional social ties and harmonizing human systems with natural ones.

The Wabanaki-Acadian old-growth forest is endangered — only one per cent of its old growth is left. The ancient forest, which stretches from parts of the Maritimes and Southern Quebec down into several New England states, is now comprised largely of newer forests, already cut down and logged, over and over.

The summer of 2026 has been defined by the smoke — and the horror — of wildfires around the world. But what comes after one of these fires? "That isn't the end of the story. That's the beginning of a whole different kind of story," says Nlaka'pamux ecologist Jennifer Grenz. That's why we have decided to follow the long-term story of one 21st century megafire: the 2021 McKay Creek wildfire in interior B.C. Producer Pauline Holdsworth returned in September 2025 — four years after the fire — to find new life emerging from the ashes, and new questions about the road ahead.

In 2021, a deadly heat dome produced a devastating wildfire season across British Columbia. While immediate media coverage often focuses on evacuations and the numbers of homes destroyed, many First Nations say what these fires do to the land in their territories — and the cultural lives of their communities — is often overlooked. "These fires are killing our way of life," says a Tmicw coordinator for the St'át'imc Chiefs Council. IDEASvisited St'át'imc territory around Lillooet, B.C. to learn how 21st-century wildfires are reshaping the landscape — and their consequences for plants, animals, and humans alike.

On the surface, bibliotherapy might sound like another personal wellness trend, but it definitely isn’t. In fact, it’s an approved form of mental health treatment in Canada. And it’s been around for at least a century. In this podcast, researchers Sara Haslam and Edmund King discuss the First World War roots of this practice in the UK. Author Cody Delistraty considers its role in moving him forward in the grieving process. And psychiatrist Martina Scholtens explains why she created an evidence-based reading list online, tailored to a range of mental health diagnoses. *This episode originally aired on June 2, 2025.

We should move away from this idea that childhood should be filled with innocence, safe from the knowledge of difficult things argues Critical Cultural Theorist of Childhood Julie Garlen. Kids do experience difficulty, even in the best of circumstances, and she suggests they need the tools and language to navigate the lives they are living. Constructing childhood as a time of innocence limits children's opportunities for growth and learning. *This episode originally aired March 27, 2025.

Hidden in the 1950 academic paper that launched the famous 'Turing Test' of machine intelligence, is a strange mystery. Cryptographer Alan Turing argued that humans might always be able to outsmart machines, because we have supernatural powers like ESP, telepathy, and telekinesis. His belief in the paranormal is just one part of the spooky side of artificial intelligence. Like hauntings or seances, AI is an exercise in self-deception; we imagine intelligence from computation and data, just like we imagine ghosts from strange lights and bumps in the night. *This episode originally aired on March 12, 2025.

If AI continues to develop without appropriate guardrails, a worst-case scenario could lead to human extinction, warns the 'godfather of artificial intelligence' Geoffrey Hinton. But the Nobel Prize winner has a solution: AI must foster 'maternal' instincts, empathy and kindness. Hinton tells host Nahlah Ayed that it's fairly inevitable AI will become smarter than humans, but if we could make it care more for us than it did about itself, good things could happen. *This episode originally aired on Feb. 18, 2026.

There is nothing random about featuring 33,000 in our number series. It's very powerful. So much so, that the number put millions of horses out of work. Inventor James Watt used “33,000 foot-pounds a minute" to measure the capabilities of a horse when trying to market his new and improved steam engine. The engine was a big success, saving horses from the drudgery of manual labour. Now, a similar process is underway with artificial intelligence — but are we the horses, or the steam engine?*This episode is part of our series, The Greatest Numbers of All Time.

Complete. Whole. Divine order. That's just the start of what makes the humble dozen extraordinary. It's one of only two numbers ever discovered in mathematics to be “sublime.” Twelve makes a number of appearances in pop culture, in religion, in non-fiction, everything from the 12 days of Christmas to the 12 people it takes to form a criminal jury. Still need convincing of 12’s perfection and indispensability? Check your watch.

Has there ever been a number more maligned in western culture than 13? So feared, it's got its own horror-film franchise. So infamously unlucky, a good many of us avoid it en masse. We've just blindly accepted its bad reputation. As part of our series, The Greatest Numbers of All Time,IDEAS explores where our irrational fear and uncomfortable feelings about 13 began. *All five episodes in our number series will be available daily in our feed this week.*

It's tempting to think suffering should be avoided at all costs, but moral suffering has its own distinct standing. It signals a moral conscience. Every day people consume real time violence, grief, war and genocide through screens and experience moral upending. Without a moral compass there’s no motivation to address necessary issues.

Homosexuality is illegal in more than half of African countries — a crime punishable by prison sentences. Or in some cases: death. In the past few years, six African countries have made it illegal just to advocate for LGBTQ+ rights. These laws bring up questions of foreign influence, neo-colonialism, and the role the international community could play in nudging human rights on the continent. *This episode originally aired on May 26, 2025.

When Jay Pitter was eight years old and out shopping with her mother, she began swaying to the music at the mall. Her mother scolded her for it — signalling that it was undignified for a Black person to act that way in public. That incident was the genesis for Black Public Joy: No Permit Or Permission Required. In her book, she addresses the self-policing Black people can internalise, and reveals how culture, urban planning, and memory shape the way people can access joy in parks, streets, transit, and neighbourhoods.

Guest in this episode:

Jay Pitter is an award-winning placemaker focused on creating joyful public spaces that foster belonging, prosperity, and cultural memory. She advances this work through cultural planning, policy frameworks, and storytelling. Pitter is also an adjunct urban planning professor and has engaged students at Cornell, Princeton, and MIT, advancing new theories of public joy that connect practice, policy, and pedagogy.

Mae West shocked audiences and infuriated censors for more than 70 years. She was pop culture’s original blonde bombshell sex-symbol comedienne provocateur. But she was more than just a corseted sex pot with an affinity for word play. She was a trailblazer, transgressive, funny, smart, sassy, lively, a genius. And she got away with all of it. IDEAS contributor Lynda Shorten explores the legacy of the eccentric Mae West.

Rachel Jedinak will never forget the day that changed her life in July 16, 1942. She was eight years old, living in Nazi-occupied France at a time known as les années noires— The Dark Years. Police rounded up Jewish men, women, and children for deportation. Rachel, her older sister and mother were among them. That morning two police offers did something that Rachel considers an act of resistance. The girls were saved. But their mother was not. IDEAS contributor Neil Sandell, based in Nice, France, explores the complicated moral territory of resistance, what it actually meant during the occupation, and maybe means now.

Our homes have been stripped of their essential humanity, says Leilani Farha, this year's CBC Massey Lecturer. Today housing has become a commodity — one fuelling the biggest industry in the world. In her lectures, Housing Inc.: A Global Takeover and Our Fight for Home, Farha calls on all of us to envision a new ideology for home — one rooted in dignity, humanity and law. “Home is required for human existence," says Farha, who served as a UN Special Rapporteur on the Right to Housing from 2014 to 2020 and is now the global director of The Shift. She speaks with Nahlah Ayed about her 25 years fighting for housing as a human right, the conversation she hopes her Massey lectures will spark and why "home is really everything."

Even if you aren't a fan of Frank L. Baum's The Wonderful Wizard of Oz, you know about the Tin man, the ruby red shoes and that the dog is named Toto. The classic story was an instant bestseller in 1900 and its popularity is still going strong with not one but a two-part prequel. For over 125 years, there have been derivative works of Oz, from Broadway musicals, films, comic books and more. IDEAS follows the proverbial yellow brick road to uncover how this seemingly simple story of friendship, self reliance and longing for home continues to speak to us. *This episode originally aired on Sept. 9, 2025.

Heated Rivalry, Love is Blind or Boyfriend on Demand all underline the global appetite for passionate swooning. But let’s not forget the source for all of it: the romance novel. It may have a reputation problem but sales in 2023 reached 39 million copies or romance fiction globally — ringing in at $1.5 billion dollars. The books and readership continue to evolve as popularity increases. What is it about romance novels that women are drawn to? Is it unhealthy escapism, harmless fun or a kind of opiate?IDEAS looks back to a 1992 episode called Paperback Love to understand the enduring acclaim of romance novels.

In the days before her medically-assisted death, journalist Elaine Dewar made it her mission to finish writing her book revealing ignored history. For more than three years, the author investigated how Canada's health care system cruelly mistreated Indigenous people — including forcing them to use segregated hospitals. Dewar's extensive research uncovers not only a shameful past, but that our collective obliviousness to it all was deliberately manufactured.

For thousands of years, estuaries were central to Indigenous agriculture on the West Coast. Then, when colonists arrived, they diked many of these ecosystems to create western farmland. Now, Cowichan Tribes is working with a group of scientists and conservationists to restore an estuary as an ecosystem and a food system — and the project has sparked an unexpected controversy. At the heart of the debate are two questions. What does agriculture really mean? And when the waters start to rise, do we work with them, or against them?

It's safe to say right now the majority of us are feeling the pinch. Grocery and fuel prices are on the rise and the income gap between the wealthy, and everyone else, continues to grow. And yet, aside from the U.S., Canada is the strongest economy of the G7. A prosperous country doesn't necessarily translate to a fuller wallet for its citizens. Host Nahlah Ayed and panelists discuss how 'prosperity' should be defined and how that can be achieved.

Driftpile Cree poet Billy-Ray Belcourt's favourite place in the world is his mother's house. It's marked with a horrible, dark past — built for nuns who ran the local residential school in Northern Alberta. Belcourt grew up in the shadow of that school. But his mom drenched this home with love so powerful it surpassed the haunted context. Belcourt's mother's house provokes questions reconciliation couldn't quite answer: what does it mean to live inside history and how do you imagine your way out? In this lecture for Vancouver Island University’s Indigenous Speaker’s Series, he makes the case for literature as a more honest reckoning.

Estuaries are a meeting of two worlds: the river and the sea. They’re incredibly fertile ecosystems that sustain 80 per cent of coastal fish and wildlife in British Columbia. For thousands of years, estuaries were central to Indigenous agriculture on parts of the West Coast. Then a new kind of agriculture arrived, profoundly altering the landscape. IDEASvisits the Cowichan Valley, where an ambitious project aims to restore an estuary — and to revitalize language, culture and traditional agriculture.

"AIDS exacerbates and accentuates inequality," Stephen Lewis said in his final CBC Massey Lectures he delivered in 2005. Back then the willingness of the world’s richest countries to help in the HIV/AID crisis was in question. The former ambassador to the UN and Canadian political leader died March 31st at 88. He will be remembered for his unwavering efforts to bring international attention to the HIV pandemic in Africa — calling out Western governments and financial institutions. This podcast revisits Lewis's Massey Lectures and his overall message to make a difference.

"I thought I understood the way the world works. I don't. I'll devote every fibre of my body to defeating this viral contagion, but I cannot abide the willful inattention of so much of the international community. I cannot expunge from my mind the heartless indifference, the criminal neglect of the last decade [1995-2005], during which time countless people have gone to their graves, people who should still be walking the open savanna of Africa." — excerpt from Stephen Lewis in his 2005 CBC Massey Lectures.
