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 wanted Black students to have a music class where they "feel they belong." 

Disgust — an emotion that makes us human. It can keep us safe from drinking milk that's gone off, thanks to the revolting smell. And as Charles Darwin suggests, disgust serves as part of our core evolutionary function. But it also has a dark side. Disgust has been co-opted by culture, to religious and political divides. Scholars say we need to reckon with this complicated emotion that has the ability to make the world more dangerous.

For centuries, Western philosophers have contemplated the question: “Who am I?” To get to the answer, 19th-century German philosopher Georg Wilhelm Friedrich Hegel suggests, start by replacing the “I” with “we.” His philosophy looks at why we should care what others think of us because people’s perspectives play a huge part in how we see ourselves and how we look at the world. His theory is that traits and habits from the people around us impact what we see in ourselves.

Humans used fire as a tool. Now we fear its destruction. But we're responsible for changing the climate, argues John Vailliant, "in a way that favours fire way more than it favours us." The Vancouver author unpacks how fire made humans who we are — and how humans are changing fire in his award-winning book, Fire Weather: The Making of a Beast.*This episode originally aired on May 29, 2024.

Homosexuality is a crime in more than half of African countries — a crime punishable by prison sentences. Or in some cases: death. New laws in some states make it illegal for anyone to even advocate for LGBTQ rights. These laws bring up questions of foreign influence, neo-colonialism, and the role the international community could and should play in nudging human rights on the continent.

No one likes talking about child sex abuse. But prevention experts say we need to bring pedophilia out of the shadows if we ever want to end abuse. They insist, it is not inevitable. CBC producer John Chipman explores an innovative new program in Kitchener, Ontario, that has sex offenders and abuse survivors working together to prevent future harm and promote healing. *This episode originally aired on Sept. 23, 2024.

America is just not that into you anymore, says historian Marci Shore. It's not us, it's them. The Yale professor blames the U.S. for the failed relationship and warns the world that her own country can no longer be counted on to defend democracy, not even within its own borders. Shore has been studying the history of totalitarianism for nearly 30 years. She tells Nahlah Ayed why she relocated to Canada and how her knowledge of Eastern Europe informed her choice.

It might seem like the vast, turbulent ocean of information we call news has always existed, but that's not the case. Theatrical plays in Elizabethan England set the stage for our modern news culture, argues Stephen Wittek in his post-doctoral work. He says the cross-pollination between theatre and news developed the norms for our contemporary public conversations. *This updated episode of Ideas from the Trenches was originally broadcast in 2014. 

It's not them, it's you. That's what fans of the cormorant argue, pointing out how people see the gangly aquatic bird all wrong. This common bird has gained a bad reputation by irritating communities with its large colonies, extreme fishing habits and tree-killing excrement. But defenders suggest maybe it's humans and their cultural assumptions that are the source of the problem. They say it's time for people to re-evaluate their perception of cormorants and acknowledge their beauty and worth. *This episode originally aired on October 6, 2021.

Music is joy declares Daniel Chua. The renowned musicologist says music and joy have an ancient correlation, from Confucius to Saint Augustine and Beethoven to The Blues. Of course there is sad music, but Chua says, it's tragic because of joy. Chua delivered the 2025 Wiegand Lecture called Music, Joy and the Good Life.

There are three components that could end constitutional democracy as we know it, says scholar Peter L. Biro — fear, habituation and what he calls 'stupidification.' He argues that we, as law-abiding average citizens, have the power to save our democracy and defend against backsliding forces. Biro recently delivered a keynote address at the ominously titled conference, Liberal Democracy in the Rearview Mirror? at Massey College in Toronto.

There are just three ingredients in the recipe that could end constitutional democracy as we know it, says scholar Peter L. Biro — fear, habituation and what he calls 'stupidification.' He argues that we, as law-abiding average citizens, have the power to save our democracy and defend against backsliding forces. Biro recently delivered a keynote address at the ominously titled conference, Liberal Democracy in the Rearview Mirror? at Massey College in Toronto.

The direction of the Cold War depended on more than the strategies of two superpowers. It also depended on psychological motivations — in particular, a desire for greatness on the part of Soviet leaders from Stalin to Gorbachev. The desire could never be satisfied, resulting in frustration and explaining why U.S. presidents’ personal behaviour toward Soviet and Russian leaders has caused outsized consequences for history, as Sergey Radchenko argues in the book that won this year’s Lionel Gelber Prize.

When she began her line of work, Métis archeologist Kisha Supernant was sometimes called a 'grave robber.' With an eye to restorative justice, she was trying to help Indigenous communities locate the graves of children who died at residential schools. Now Supernant is called to find children's graves. She uses both traditional knowledge systems, as well as cutting-edge ground radar techniques to help families and communities begin to heal. It’s a science, she says, of the heart and head.

In the past decade, there has been one stable voting bloc: white evangelical Christians. Their has been at a constant 80 per cent for Donald Trump, according to historian Kristin Kobes Du Mez. In her book, Jesus and John Wayne, she describes the Trump era as the latest chapter in a long story of exclusion, patriarchy, and Christian nationalism in the evangelical church. *This episode originally aired on Oct. 18, 2024. 

We're not dealing with a future problem with AI systems, it's a now problem, warns MIT researcher Joy Buolamwini. Grave consequences of encoded discrimination are embedded in AI systems — racial bias, sex and gender bias and ableism — posing unprecedented threats to humankind. The founder of Algorithmic Justice League, a movement to prevent AI harms, has been at the forefront of AI research. She encourages experts and non-experts to in the fight for "algorithmic justice." Her book, Unmasking AI: My Mission to Protect What Is Human in a World of Machines, uncovers the existential risks produced by Big Tech. As she says, "AI should be for the people and by the people, not just the privileged few.”

International law is clear: warring parties cannot kill civilians. It's a war crime. But there is one exception. An attacker can justify killing them if they’re being used as a human shield, involuntarily. IDEAS explores the long history of humans as shields and how this legal loophole has become a norm.  Guests include Nicola Perugini, who teaches international relations at the University of Edinburgh. He is also co-author of Human Shields: A History of People in the Line of Fire. And Dr. Mimi Syed, an American emergency medicine physician who served two medical missions in Gaza in 2024.

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. 

On May 5, 1945, Canadian soldiers played a key role in the liberation of the Netherlands from the German forces. Almost 80 years later, a large group of Canadians travelled to the Netherlands to pay tribute to their relatives who'd helped liberate the country in the Second World War. They walked on a nine-day pilgrimage through villages and towns, visiting old battlefields and the cemeteries where Canada's soldiers are buried. The group followed in the footsteps of the Canadian troops to honour their sacrifices. *This episode originally aired on May 1, 2023.

In the hour’s following her mother’s death, Martha Baillie undertook two rituals — preparing a death mask of her mother’s face, and washing her mother’s body. That intimacy shaped her grief. She had learned earlier to witness death and be present, living with regret after she left the room to get a nurse when her father died. It was very hard for Baillie to see mother's body as a corpse that has no life. To her, it would "always be something alive." The novelist and writer explains what signified the difference in her book, There Is No Blue, the 2024 winner of the Hilary Weston Writers’ Trust Prize for Nonfiction.
