In the third episode of our series The Billionaire Agewe investigate how Musk and his fellow billionaires are trying to take over the world. And if they succeed, what will this mean for the rest of us?

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.

A young generation of thinkers is trading in the bread and butter of social media branding — lifestyle, beauty, and consumption — for intellectual content. They focus on the big questions to help followers think about a world where they can't find jobs, are overloaded with debt, and see violence everywhere. It's the kind of education money can't buy.

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.

"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.

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.

History has never seen such an extreme concentration of wealth. Some economists argue the battle of the 21st century is between oligarchy and democracy. How did we get here? IDEAS begins a four-part documentary series The Billionaire Age.

Earthworms are supposed to be a sign of healthy soil. But they're actually an invasive species that can even damage forests. So have we been sold a lie about worms and soil? Not exactly. The relationship between the two depends on the context. And the way we garden — or farm — can make all the difference. IDEAS producer Annie Bender unearths the complicated truth about the not-so lowly earthworm.

The investigative journalist argues AI companies run their businesses like empires and it has to stop. In her 2025 bestseller, Empire of AI, Hao digs into the global impact of Big AI and explores how we need to rethink AI to build a better future. This podcast includes a lecture by Karen Hao and a discussion with host Nahlah Ayed.

Fact and fiction may seem poles apart but writers Esi Edugyan and Tiya Miles find the two intertwine perfectly in their award-winning storytelling. Both authors try to imagine past lives in their work, in part so that we may reimagine our own. They may operate in different realms but what they share is the telling of profoundly important stories that would otherwise go untold. It's been a longtime goal forIDEAS to bring these two accomplished authors together for a discussion — and it was worth the wait.

This podcast was recorded in front of an audience in January 2026 at a Toronto Public Library event.

Poetry can find you when you need it most. It can be life-altering to read that poem just at the right moment. It was for six IDEAS producers who join Nahlah Ayed in studio to share poems they return to, year after year.

This special episode is to mark UNESCO's World Poetry Day, March 21st.

A case before the Supreme Court of Canada is challenging Quebec’s law on secularism. Legal scholar Benjamin Berger is a prominent voice in the study of constitutional and criminal law in Canada. He argues secularism "is a concept that hides more than it shows." In this podcast, Berger examines how secularism obscures the impact of religion on our legal and political systems. "We end up speaking abstractly about what secularism is, what it demands, instead of whether our government is treating people equally and fairly."

Benjamin Berger is professor at Osgoode Hall Law School of York University. He delivered Memorial University’s 2026 Henrietta Harvey Distinguished Lecture.

If journalist Vince Beiser had his way the term 'clean energy' wouldn't exist — it's a misnomer. He argues green energy comes with cost. Sure, solar power or wind power are both better than power from fossil fuels but Beiser points out they are still harmful to the planet and people. "There's no magic solution." Beiser tellsIDEASwe need to shift to renewable energy but we also need to recognize it's not a "magic solution" — there is a downside with consequences.

Vince Beiser's book is called Power Metal: The Race for the Resources that Will Shape the Future.

Port cities are where worlds collide. They are a place of cultural, economic, political and religious contact. They've existed for millennia and facilitated the birth of empires and the rise of a globalized economy. Without port cities, our world would look very different. In the first episode of our series on how port cities shaped the world as we know it, UBC journalism professor Kamal Al-Solaylee visits Singapore — a constantly-evolving port city whose maritime roots go back to the 13th century. 

“One of your tribe is enough.” That’s what Margaret Rossiter was told when she said she wanted to study female scientists. Nevertheless, Rossiter persisted. She found and documented hundreds of women whose contributions to science had been overlooked, under-credited and misappropriated. Then she made history herself by coining the term “The Matilda Effect” to describe why those women failed to get the credit they deserved.

Who is Matilda? Matilda Joslyn Gage was a suffragist erased from history. She was known as being too radical for Susan B. Anthony. This podcast shares her story.

One of the strongest ties between the diaspora and home is music. In Iran, music can be politically contentious. In Canada, it connects a community to its past and to its future. Days after the bombings began in Iran, Nahlah Ayed spoke to three Iranian-Canadian musicians and composers about the role of music in a time of uncertainty.

"Music can be an escape, can be a consolation... Like if we are the stars and galaxies on the planets of the universe, music is like the dark matter of that universe. It's that gravitational force that we know is there but we can't quite put our finger on it." — composer and pianist Iman Habibi

Guests in this episode:

Tahare Falahati is a Persian traditional singer

Kaveh Mirhosseini is an Iranian composer and conductor

Iman Habibi is a composer and pianist

Mathematics is everywhere: a common refrain from high school math teachers. But did you ever think math could be linked to literature? And not just in works from the literary greats of the past but for example Michael Crichton's Jurassic Park. The relationship between math and literature are fundamentally creative, says Sarah Hart, a mathematician and author who speaks to Nahlah Ayed about how these two things that seem so polar opposite are deeply intertwined.

Sarah Hart's book is called Once Upon a Prime: The Wondrous Connections Between Mathematics and Literature.

It is possible. Flavours have been lost to the past, as culinary physicist Lenore Newman explains. She points to the extinction of the passenger pigeon — a species numbering in the billions throughout North America — as an example. In 1914, Martha, the last passenger pigeon, died at the Cincinnati zoo — and in place of the pigeon, came the industrialized farming of chicken. Newman says we're now transitioning to lab-raised food — a technology capable of pushing a global history of scarcity into one of abundance, all the while easing land usage. She calls it the "food singularity."

At a time when the future of Iran is uncertain, we revisit an IDEAS documentary about the history of women’s resistance in Iran — women who in 1979 harboured dreams of freedom and democracy. After ousting the Shah, and mere weeks after Ayatollah Khomeini took power, Iranian women marched to show their fury at the revolution. Forty years after their protest, documentary maker Donya Ziaee spoke to three Iranian women who were there, fighting to turn the tide of history. *This episode originally aired on March 8, 2019.

Accusations of a stolen election, laws targeting NGOs and media, violent treatment of protestors — sometimes live on TV. What’s happening in the republic of Georgia right now typifies what is happening geopolitically around the world. The authoritarian ruling party called Georgian Dream aligns itself with Russia but most citizens want the country to join the European Union. There have been 400 consecutive days of protests before 2026 against the Georgian Dream government.

Radio documentary makers David Zane Mairowitz and Malgorzata Zerwe were in the capital Tbilisi, and to record the Family Purity Parade and a demonstration, each from opposing ends of the political spectrum, for this documentary.

That’s what Hanna Pickard argues. After analyzing the scientific research, and working with those who’ve stopped self-destructive drug and alcohol use, the Johns Hopkins philosopher sees addiction as a complex behavioural disorder. She argues it’s driven by individual psychology and social circumstances, and should be treated that way. Jowita Bydlowska and Michael Kaufmann, both memoirists of addiction, weigh in.

Connie Greyeyes describes herself as an ‘accidental activist.’ After her cousin was murdered and her childhood best friend went missing, she started organizing vigils for missing and murdered Indigenous women in Fort St. John, B.C. — then asking questions about the relationship between resource extraction and violence against women. This episode is the first in a series of profiles of human rights defenders, recorded alongside the 2025 CBC Massey Lectures. 

You likely have never heard of Matilda Joslyn Gage. Gloria Steinem calls her “the woman ahead of the women who were ahead of their time.” Matilda worked side by side with Susan B. Anthony and Elizabeth Cady Stanton to get women the vote in the United States and co-wrote the history of the women’s movement with them. IDEASproducer Dawna Dingwall looks into why the towering figure was erased by her peers, and the work that is being done to write Matilda back into history.

"The Matilda Effect" was a term coined by a historian Margaret Rossiter to describe women whose work had been overlooked and erased from history, like Matilda Gage. Listen to this podcastto hear about the lost women of science and how Rossiter gave them the credit they deserved.

There are two things most people agree on — artificial intelligence is rapidly advancing, and the grave risks AI poses are very real — no one, not even ChatGPT, really knows how this will play out. Renowned “Godfather of AI” Geoffrey Hinton argues we need to put the brakes on AI development until we know for sure it can be kept safely under control.

Owain Evans is a leading AI researcher and the founder/director of Truthful AI. In his 2025 Hinton lecture series, organized by the AI Safety Foundation, he discusses the risks presented by AI, the means at our disposal to keep it escaping human control, and the challenges of developing coherent, comprehensive strategies to prevent AI from becoming a menace to humankind.

It was a simple honeymoon photo from 1941. A stranger posted it online and the commentary was vicious. The woman in that picture was Albanian author Lea Ypi’s grandmother. In the midst of the Second World War and the violent end times of Mussolini’s government, Ypi’s grandmother must have been a fascist, a collaborator, a traitor to Albania. In her book, Indignity: A Life Reimagined, Ypi attempts to find the truth of her grandmother’s life, in a journey that mixes philosophy, fantasy, history, and family narrative.

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.

IDEAS producer Tom Howell recently sold his car and joined the ranks of winter cyclists in Montreal. He is not the only one who commutes on bike in North America’s snowiest metropolis. The city’s bike-sharing program operates year-round. The bicycle’s popularity as a winter vehicle is increasing. Nevertheless, winter bicycling remains a minority practice, often viewed as folly. Howell investigates whether there is indeed wisdom in it.

Under pressure, our nerves can take over. At job interviews, performing in front of an audience and it's definitely present in sports. But why do our skills desert us at such a crucial moment? And what can be done to avoid choking? Studies have shown that when people tell themselves they're excited rather than nervous, they perform better. This podcast explores more ways to avoid the choke and why it happens. *This episode originally aired on Nov. 23, 2022.

In freedom, he uses his escape box as the basis for a subversive magic act that sees him tour the stages of the UK and Canada — his final home. Henry's remarkable story is a must-listen. *This episode originally aired on Feb. 3, 2025.

With vengeful alien civilizations and hologram wives, Chinese science fiction is in its heyday. One hot topic discussion is how the genre and culture view things as "inherently non-binary," says PhD student Zichuan Gan. Not just in the sense of gender but avoiding black and white categories. As in "humans or machines, west or east, Chinese science-fiction often shows that reality and life are more mixed and complicated." IDEAS explores what we can learn from China through it's science fiction. *This episode originally aired on Sept. 2, 2025.

Neither the legal system nor the Constitution can change the course of the United States’ descent into illiberalism, argues human rights and civil liberties lawyer Jameel Jaffer. Only the will of the people can — when ordinary citizens fight to uphold democracy with "civic courage."

Mudlarking is a hobby that's having a moment. The opportunity to take part in the painstaking, low-tech scrape through history draws thousands of people hoping to come face to face with the remnants of lives that came before them.

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.

More than a decade before Jackie Robinson became the first Black player to take the field in Major League Baseball, a ball team from a small Southwestern Ontario city was breaking colour barriers. They were called the

Chatham Coloured All-Stars — the first all-Black team to win the Ontario baseball championship. Their historic 1934 season, including the racist treatment they endured and their exploits on the field has resurfaced in an online project. Now the team is getting their due as trailblazing Black Canadian athletes. *This episode originally dropped on Nov. 25, 2024.

Firstly, you might ask: What is the Monroe Doctrine? It's a U.S. policy created in the 19th century that opposes foreign interference in the affairs of the "Western Hemisphere." It was understood to be a defense of autonomy but its interpretation is mixed. Various presidents over time have used the doctrine for their own purposes, writing their own political agenda onto it. Now is no different, as Donald Trump's government turns to the policy as a way to control the Western Hemisphere.

You've likely experienced it: that state of being in the groove, on a roll, lost in the process. It's what researchers call 'flow': a state intimately familiar to athletes and artists — or anyone who's been fully absorbed in a given task to the point where time seems to stand still. In this state there's a sense of self disappearing, presenting a paradox between a state in which you lose yourself, yet become yourself. Writer and triathlete, Suzanne Zelazo, delves into the mystery at the heart of flow in this documentary.

"We are in the midst of a rupture, not a transition," Canada's Prime Minster Mark Carney said in a recent speech at the World Economic Forum. The shift in international relations has Carney urging middle power countries to build coalitions and act together to counteract the great power strategy of the day: coercion. How? By flexing our "soft power" — assets a country has that appeal to other countries in international affairs. As it turns out, Canada and a majority of other countries have an opportunity to play a significant role on the international stage, if they choose to take it.

ThisIDEAS episode is a discussion with Jennifer Welsh, McGill University’s Canada Research Chair in Global Governance and Security, moderated by Nahlah Ayed, at the University of Ottawa in the fall of 2025. We also hear from former high commissioner to Britain Janice Charette, former head of MSF Dr. Joanne Liu and climate campaigner Catherine Abreu.

Our justice system was developed under the assumption that both parties in a dispute would each have a lawyer. But the reality is most Canadian's can't afford a lawyer — which makes negotiations unequal. In some jurisdictions as many as 80% of people in family court are self represented. What about legal aid? Very few people are eligible. Our series continues to explore how the justice system is designed to favour people with money. *This episode originally aired on April 26, 2023.

Marcell Wilson knows how to game the criminal justice system. He's been charged upwards of 30 times for what he says were “mostly violent crimes" and yet to this day he doesn't have a criminal record. Why? He has money to pay the high fees for a good lawyer. Many scholars and legal commentators agree it’s easier for people with wealth to secure favourable legal outcomes — not just in criminal court but in custody disputes, civil litigation, and child protection matters. In a two-part series,IDEAScontributor Mitchell Stuart asks: is a system like that still capable of administering justice?*This episode originally aired on April 19, 2023.

It depends on who you ask. Until recently empathy was generally considered a positive thing. But a growing number of mostly conservative voices believe empathy can be extremely dangerous — even toxic. Their argument is that empathy can drive irrational thinking and behaviour in public life. The result is a growing battle over empathy in a world that has never seemed to need it more.

"You're awakening a dragon. Public anger is stirring." A warning from Rutger Bregman to Silicon Valley. The historian is sounding the alarm over the existential risks posed by unrestrained technology and artificial intelligence in his final BBC Reith Lecture. He calls on those in power to assume responsibility, and help shape a future worthy of hope. Bregman envisions 'moral revolutions' as the path forward and urges us all to come together to take on this task. "Small groups of committed citizens have bent the arc of history towards justice. And whatever the outcome, there is beauty in trying, beauty in every act of courage, in every spark of truth."

The potato and the Irish Famine of 1845 will forever be linked. But what's often overlooked is how deeply connected the potato was to British colonial policies during that time. To Britain it was a symbol of Irish backwardness. In the book Rot, a new history of Ireland's Great Famine is revealed, showing how the British Empire caused the infamous disaster. Author and historian Padraic X Scanlan paints a complex and compelling picture of the Irish Famine of 1845, in which the potato — and the blight — played but a part in a broader story of colonialism, capitalism, and collapse.

We are all born. Birth is the story of us all. So why aren’t we more curious about its history? That's what historian Lucy Inglis wanted to know. She's spent 15 years researching birth — around the globe, and across the centuries. “When you go into labour, you are a ship on the sea," says Inglis, referring to an ancient Assyrian chant acknowledging the physical perils of giving birth. While medical advances and greater freedom of choice inform birth in countries like England and Canada today, her book Born: A History of Childbirth argues that birth has a deep global history that proves it has always been a highwire act, shaped by both nature and culture.IDEAS explores the visceral, intimate realities of childbirth that have always been in evidence.

What's the secret weapon to make political change happen? It's not a trick question, it's simple: perseverance, says BBC Reith Lecturer Rutger Bregman. The historian envisions a "realist utopia" in this lecture and asks listeners to join what he describes as a “conspiracy of decency" — a world where Universal Basic Income, fairer taxation and stronger tech regulation can start to build a more just and resilient future. A great movement Bregman says needs radicals who push the fringes but also moderates "who are actually able to make compromises and get things done." There's a role for everyone just find a small group of committed, determined, morally-serious people and "then you can move mountains."

We live in an "age of immorality," argues historian and author Rutger Bregman. "The moral rot runs deep across elite institutions of every stripe," Bregman says in his first BBC Reith Lecture. His series of lectures describes why he is calling for a moral revolution to counter the culture of cynicism and un-seriousness among global elites. Bregman says history has proven how small determined groups have catalysed profound moral change, and that legacy should be an inspirational guide for all of us today.IDEAS is featuring lectures from the BBC Reith Lectures, this is the first episode.

This podcast seeks answers to the question. If you are left-handed then you are part of the 10 per cent of humankind that detested craft time in elementary school that involved scissors. Left-handed people often have to accommodate their difference in our dominant right-handed world. But that can get tricky if you are training to be a surgeon. Operating rooms and surgical instruments become big obstacles for left-handed people as IDEAScontributor Mark Dance finds out in his documentary exploring the history and mystery of left-handers. *This episode originally aired on May 6, 2022.

Think of science's most momentous developments in the 20th century — Einstein’s theory of relativity, quantum physics, finding evidence of black holes. If you trace the chain of discoveries that led to these breakthroughs back far enough, you’ll end up with the Italian astronomer and physicist Galileo Galilei. Theoretical physicist Carlo Rovelli says we can learn a lot from Galileo today. He explains how 400 years ago, the renowned inventor was discovering new facts about the Universe to understand ourselves better — and so are we.

"This is a hopeless situation but we are not helpless." This is what drives Sudanese journalist Yousra Elbagir's reporting on her homeland's forgotten war. She uses what she calls "human reporting" to let the world know Sudan is more than conflict and suffering. "Sudanese generosity is our lifeblood. That's what's keeping us alive right now. We are actually surviving in forced starvation through generosity and kindness and care."

Yousra Elbagir delivered the 2025 Stursberg Foreign Correspondents Lecture at Carleton University. She spoke to host Nahlah Ayed about her work and her lecture: Human reporting from Sudan and beyond — a remedy for selective empathy?

"Those who remember the disappeared would also disappear." Under dictator Bashar al-Assad, grieving publicly in Syria was punishable. Now the silenced stories of lost loved ones are emerging and there are public spaces to grieve. Syrian architect Ammar Azzouz's friend and colleague Taher Al Sebai was killed on his street in 2011. After 14 years in exile, Azzouz returned home and says it's not just a right but "a duty to remember." IDEAS hears about Azzouz's classmate from architecture school, the lives of a father, a brother, and a singer who became the voice of the revolution.

It's getting pretty difficult to read any article online without a paywall in the way. What happened to the internet's great promise to democratize knowledge? On an individual basis, artists, writers and scientists can create without fear of theft thanks to copyright laws. But in practice copyright laws set up barriers, stifle production and prevent equal access to art and research. In this podcast, producer Naheed Mustafa explores the fate of “open access” — all in the ever-expanding universe of copyright laws, paywalls and old-fashioned bureaucratic sludge.

Guests in this podcast:

John Willinsky is emeritus professor of education at Stanford University with an appointment at Simon Fraser University.

Lokesh Vyas is pursuing a PhD at Sciences Po in Paris working on the history of international copyright law.

Thea Lim is a Toronto-based novelist, creative writing teacher, and cultural writer focussing on the intersection of power, art and personhood, and technology.

We gorge ourselves on the internet, smartphones, social media, information overload — all of it constantly sap us of our emotional and intellectual vitality. Authors Pico Iyer and Jonathan Haidt argue it's vital we disconnect from our addictive online world to pursue a fulfilling, and richer life. By curtailing the noise of technology, media and other worldly distractions there's space to reconnect with the things that matter. "Humans were never designed to live at a pace determined by machines. The only way we could begin to do that is by becoming machines ourselves," says Iyer.

Pico Iyer and Jonathan Haidt were two of the marquee speakers at the 2025 Aspen Ideas Festival. The theme this year was 'What Makes Life Good.'

Holmes Rolston III began his career as a Presbyterian minister. But his love of the natural world — and his belief in evolution — didn't sit well with his congregation. He was ultimately fired. The late philosopher spent much of his career working to bridge the gap between science and religion because he said "the future of Earth depends on it." Rolston is the pioneer of environmental ethics, a turning point in philosophy. His ultimate goal was to define the moral worth of the planet. Rolston died in 2025 at the age of 92.

In this episode,IDEAS explores his legacy and the continuing resonance of his work.

Would you 'doo-be-doo' if you know it would help bridge divides? Try vocal improvisation — singing sounds, rhythms and melodies. PhD candidate Erwan Noblet teaches the practice and says it's a great way to open up and connect at another level being together. He believes the human voice has the power to communicate creatively when it's released from everyday verbal tasks. We asked three former politicians from different political parties to communicate through vocalization, without words. Their conversation may inspire you to take on vocal improv.

What do you get when you take some of the classic Enlightenment values like reason, fairness, and justice, and substitute them with opinion, privilege and power: The Dark Enlightenment — a movement that is a deliberate oxymoron with a vision to dump democracy and replace it with start-up cities run by CEOs. American blogger Curtis Yarvin, also known by the pen name Mencius Moldbug, is the founder of this movement that advocates for the return of traditional hierarchical societies and monarchy-like governance.

If we weren't so used to having books, we would think of them as a "miracle." That's how historian Irene Vallego

views what she says is humankind's greatest and most influential invention: the book. "With their help, humanity has undergone an extraordinary acceleration of history, development, and progress," she tells host Nahlah Ayed. Vallego has traced written texts back to their earliest origins and she's written a book of her own, Papyrus: The Invention of Books in the Ancient World. 

If you think you've never heard Jerry Granelli play drums — you likely have. Think of a comic strip holiday special and an iconic soundtrack: A Charlie Brown Christmas. Jerry was 22 years old when he became a member of the Vince Guaraldi Trio, the jazz band behind the popular 1965 album. His long career was legendary, accompanying many of the greats like Mose Alison, Sly Stone and The Grateful Dead. Producer Mary Lynk was lucky to meet with Jerry on the eve of his 80th birthday for a wide-ranging conversation. The gifted composer and jazz giant died in Halifax in 2021. *This episode originally aired on December 21, 2020.

Handel’s Messiah is one of the best-loved pieces of Christmas music. Only it was meant for Easter. But it draws on far more from the Old Testament than the New. There are more surprising facts about this 18th-century masterpiece thatIDEAS explores with Ivars Taurins, founding director of the Tafelmusik Chamber Choir who has conducted Messiah over 200 times, and veteran CBC Radio broadcaster Robert Harris. In nine movements, they reveal the hidden treasures of Handel’s celebrated work. *This episode originally aired in 2015.

The nativity story that Christians believe is that God took the form of a baby named Jesus who was born to save the world and bring about an enduring peace. So what happened? Did we miss it? And what happens next? These are questions Trappist monk Thomas Merton grappled with in his own meditation on the Christmas story. His version "The Time of The End is the Time of No Room" was published in 1966. At the time he called it a sober statement about the climate of our time, a time of finality and fulfillment.
