We're not machines. Why should our online world define life?

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....

'Dialogue between science and religion matters to the planet'

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 di...

The most famous French-Canadian novel you've never heard of

Maria Chapdelaine: A Tale of French Canada is one of the most widely read works of fiction ever written in French. It's considered the world's highest-selling French book. Yet today, the 1913 novel remains far less known in English Canada and the English-speaking world. Translated into over 20 languages, the book's character Maria and her story has inspired four film versions, several plays, an opera, and even a pop song. Contributor Catherine Annau examines the many lives that Maria Chapdelaine...

When words get in the way, vocal improv saves the day

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 c...

Ditch democracy. This movement wants tech-elites to govern

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-li...

Why autonomy is vital to MAID law and the right to die

Bioethicist Arthur Schafer has thought a lot about life and death. He's helped shape policy on medically assisted death (MAID) in Canada. The philosophy professor argues that an ideal end-of-life legislation would respect individual choice and the wishes of individuals to die according to their own values. "The best ethical argument is that patient autonomy is a fundamental value," Schafer told host Nahlah Ayed. He discusses the role of philosophy in addressing complex ethical dilemmas confronti...

Could resetting the body's clock help cure jet lag?

Kritika Vashishtha has been pursuing a cure for jet lag and it's possible she's found the answer.

How the invention of the book shaped humanity

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....

Hallelujah! Let the light of Black gospel shine 101

When Darren Hamilton began university, he was shocked to find that there were no Black music courses and Black music professors. He grew up singing spirituals every Sunday in church. Now at the University of Toronto, Hamilton teaches Gospel Choir, U of T's first credit course in Black gospel music. Students of all backgrounds and ages come to learn and sing songs rooted in faith, freedom and joy. He says he started the course because he wanted Black music to be valued in music education, and he ...

Jazz fan or not, you've probably heard this musician play

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-rangin...

Revealing facts about the Christmas song meant for Easter

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 that IDEAS 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 epi...

An apocalyptic retelling of the Christmas story

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 f...

Where to find 'critical hope' in hard times

In an era of political polarization and fatigue from ongoing crises, hope is critical. But it's not something you have; it's something you do, argues education scholar Kari Grain. "Critical hope" in action is not just the belief that transformation is possible — it's necessary. In her book, she explores seven principles for practicing hope that confront toxic positivity, social injustices, and gives anger and grief a seat at the table. Kari Grain is a professor at the University of British Colum...

Why spirituality is central to Indigenous mathematics

Indigenous math isn't just about numbers and equations, it involves culture, spirituality and more. Math professor Edward Doolittle, a Mohawk from Six Nations in Ontario, sees math as something embedded in Creation itself. In his Hagey Lecture at the University of Waterloo, he describes Indigenous mathematics as being grounded in cognition, emotion, the physical world and community. Indigenizing math, Doolittle hopes, will make it more approachable and meaningful to Indigenous students — show th...

How 'body horror' helps us confront the fears within us

"We are the monsters" — that's the premise for the genre of film known as body horror — movies that fixate on monstrous and grotesque changes to the body. There have been good body horror films and bad ones, but "The Fly" starring Jeff Goldblum and Geena Davis was perhaps the most consequential. The movie captured anxieties around bodily autonomy and physical decay, just as the AIDS epidemic was becoming catastrophic. Forty years later, Body Horror is back with films like "The Substance" and "To...

How to change minds and find common ground

In 2024, 'polarization' was Merriam-Webster's word of the year. That division still grows, making it increasingly difficult to connect to one another. But there are people having important conversations and they have advice for us all. From fighting for LGBTQ+ rights in Colombia, championing human rights in Southern Africa and working for a two-state solution post Oct. 7, the winners of the The Global Centre for Pluralism awards tell host Nahlah Ayed about how minds can and do change, and why we...

The 'dangerous' promise of a techno-utopian future

Tech billionaires are on a mission to make the stories of science fiction a reality: space colonization, human/machine bio organisms, and living forever in a state of unhindered bliss. This version of a far future utopia may come of as a "billionaire boys and their toys" but experts warn such a dismissive attitude is naïve and dangerous. *This episode originally aired on Jan. 22, 2025.

Bringing a farm — and its philosophy — back to life

Growing up with food insecurity, Julian Napoleon yearned to be a farmer. His great-grandparents once farmed on the Saulteau First Nations reserve in northeastern B.C. Over the decades, the farm was replaced by the bush, and the ideas of communal, seasonal living started to fade away. Five years ago, Julian moved to Amisk Farm to bring it back to life. This year the farm has produced food for over 300 Indigenous households, free of cost. IDEAS visits Amisk Farm to learn about rural food security,...

Pt 2 | Architect Frank Gehry on how to exit life

There’s a constant mantra Frank Gehry would always hear from his mentors who have since died – “Don’t you dare ever stop working.” It’s a sentiment he lived by right until his death at 96. In fact his last major cultural building, the Guggenheim Abu Dhabi, will open in 2026. So how does his fierce, creative drive square with his mortality? In an expansive conversation from 2017 with IDEAS producer Mary Lynk, Gehry shares his thoughts about death and his life, from growing up Jewish in Toronto, t...

Pt 1 | The architecture that brought Frank Gehry to tears

Rebel architect Frank Gehry believed architecture IS art. He strived to evoke emotion in every design. Last Friday, Gehry died at 96 but he never stopped creating. In 2017, IDEAS producer Mary Lynk had a rare opportunity to spend two days with Gehry at his LA studio. Their wide-ranging conversation covers many aspects of his life and career, including a moment at 40 when the sight of an ancient piece of art from 500 BC led him to weep. "I think if you went and looked at it, you would cry too," h...

How music transports the Afghan diaspora to their homeland

For Afghans, listening to a traditional song can bring them back "home." In 2021, when the Taliban seized power again in Afghanistan, orchestras disbanded and musicians fled for their lives. They brought with them their distinctive and storied music, embedded with notes hailing from classical music from Iran and India. IDEAS takes a journey to Afghanistan with members of the Afghan diaspora, and asks how the idea of home is encapsulated in music and how conflict has played a role in reshaping Af...

Why cities are targeted in wartime (updated)

In 2022, IDEAS explored how the brutal strategy called "urbicide" — the intentional killing of a city — is used in war to destroy residents' sense of home and belonging. This podcast revisits the original story and includes a brief update from architect Ammar Azzouz. Since the collapse of the Assad regime last year, he has returned to Homs, Syria, twice.

Why hospitals stopped being hospitable

Hospitality — and hospitals. Two words that share a root, but whose meanings often seem at odds with each other. IDEAS traces the historical roots of hospitals, the tension between hospitality and discipline that has defined hospitals throughout their history, and what it means to create a hospitable hospital in the 21st century. *This is the third episode in our series, The Idea of Home, which originally aired on June 15, 2022.

How guest-host power dynamics shape migration

In ancient Greece, hospitality (or xenia) was seen as a sacred moral imperative. Someone who defied the obligations placed on both host and guest risked the wrath of the gods, or even outright war. Today, the word xenia has largely fallen out of use, but its opposite, xenophobia, has been a driving factor in contemporary politics for years. IDEAS explores ancient traditions of hospitality in this second episode of our five-part series, The Idea of Home . *This episode originally aired on June 14...

Can you ever truly return home again?

At age 11, writer Andrew Lam fled Vietnam during the Fall of Saigon. Nearly 45 years later, he returned to a radically different city. He believes "you will be cursed with longing" if you continue to search for the feeling of home you had in the past. At a time when more people have been forcibly displaced from their homes than at any other time in history, IDEAS explores what it means to return home years — or decades — later. *This is the first episode in our five-part series, The Idea of Home...

Buttons give the illusion of power but hide the consequences

Whether mechanical or digital, a button delivers the promise of power — but it's far from simple. The small and mighty technology has a riveting history, a story of control, power, freedom and oppression.

How overlooked veterans make history in their own words

There’s history, and then there’s oral history. And when it comes to the impacts of war on those who fight them — oral history opens doors to the past that would otherwise stay firmly shut. Michael Petrou, an historian with the Canadian War Museum, argues oral history is especially valuable because it allows us to hear from people "whose voices are quiet, downplayed, or ignored." Their untold stories provide a fuller picture of how war shapes people and societies.

Why Canadian veterans are conflicted about Remembrance Day

Remembrance Day. Every year we are called on to remember, to reflect on the sacrifices of those who fought in Canada’s wars. Veterans of those wars have a conflicted relationship with Remembrance Day: sometimes their own acts of remembrance include official ceremonies, while others avoid them altogether. *This the second and last of a two-part series exploring the post-war experience, gathered by the Canadian War Museum’s In Their Own Voices oral history project....
