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 origin...

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....

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 Dea...

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 Rober...

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...

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 giv...

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 m...

"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...

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 T...

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.

This isn't a wrap or best of 2025 kind of list. This IDEAS podcast is packed full of all kinds of recommendations from our smart, insightful contributors. We asked them to suggest a work of nonfiction that recently made them think — maybe even think differently — about a particular topic. Their answers cover several genres and varied subjects. Some may surprise you. Don't worry about writing any t...

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...

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...

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 pi...

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 a...

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. He tells IDEAS he has mixed emotions being...

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, wh...

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...

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 h...

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. From the podcast Media Objects , this episode traces the evolution of the button, and asks what happens when every command is reduced to a single press.

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 stor...

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...

Even when wars end, they go on — transforming the people who fought them, their families, and even society. A former war correspondent interviewed more than 200 veterans of all of Canada’s wars for an online oral history project by The Canadian War Museum. The focus is not so much on preserving memories of their combat experiences, but to reflect on what came after.  *This is part one of a tw...

Look back about 3,000 years and you will find the playbook on authoritarianism remains pretty much the same as it is today. Back in the 5th century BCE, when Herodotus travelled the ancient world gathering stories, he became an expert in would-be tyrants. His tome, The History , shared vivid descriptions of autocratic and tyrannical rulers. Herodotus was a rule breaker himself. He ignored Greek li...

For someone who died more than 2,400 years ago, Herodotus's voice is still very much alive. "He knows the way [a good story] can elevate but also corrupt and destroy our thinking," says professor Lindsay Mahon Rathnam in this IDEAS episode. The ancient Greek writer observed different cultures first-hand, while capturing the stories they share in an attempt to better understand how they came into b...
