Universities have always been places of protest and dissent, but University of Toronto English professor Randy Boyagoda argues that it should be something more — a place for productive discourse. He says we must check the assumption that our lived experience, well-formed arguments, or even knee-jerk responses are all there is to any given matter. That means staying open to the possibility of being wrong.In January 2024, he became the university’s Advisor on Civil Discourse, the first position of its kind in Canada, prompted in part by campus convulsions since October 7th. Boyagoda explores the question: what are universities for? *This episode originally aired on Oct. 7, 2024.

After more than four decades of activism and advocacy, David Suzuki is one of the most renowned and respected voices in the environmental movement. So when he says it's too late to stop climate change, people take notice. And that's now exactly what he's saying.He's delivering this message as Prime Minister Mark Carney's government focuses on fast-tracking major projects it deems to be of national interest, which could include a new pipeline for fossil fuels from Alberta. Suzuki says that, despite his understanding of the climate crisis, Carney — like all of us — is trapped by the economic and political systems we've created. And for Suzuki, our only hope for survival is to scrap those systems entirely.In this special episode from our colleagues at Front Burner, David Suzuki joins host Jayme Poisson on the podcast for a wide-ranging discussion from what a world of irreversible climate change looks like to what he describes as the "madness" of continued investment in fossil fuels to the lessons environmentalists of the future can take from the past.

“The future doesn't exist. The only thing that exists is now and our memory of what happened in the past. But because we invented the idea of a future, we're the only animal that realized we can affect the future by what we do today," says David Suzuki. For 44 years, the former host of The Nature of Things shared the beauty of the natural world and taught us about our moral responsibility that comes with being alive. In this episode, the award-winning scientist and environmentalist shares his life lessons as a proud elder. *This episode originally aired on June 8, 2023.

For nearly 70 years, filmmaker Alanis Obomsawin's storytelling and documentary work have served as a mirror for Canada, reflecting Indigenous experiences and providing a space for all Canadians to witness perspectives that have otherwise been ignored.

His research led him to a shift in his view on our much-vaunted intelligence. *This episode originally aired on June 22, 2023.

The great divide in politics is all around us. Sometimes the best way to engage in a difference of opinion is to 'pass it by.' Political theorist Shalini Satkunanandan suggests we take that lesson from Friedrich Nietzsche's philosophy. Yeah, that guy — the one most known for his wrestling with nihilism. Satkunanandan argues that the constant need to engage and correct, refute or criticize "is making partisan divides even more pronounced." She views Nietzsche's method as a valuable way to navigate the highly polarized discourse of today. *This episode originally aired on Jan. 20, 2025.

Composer Christos Hatzis discusses the meaning and enduring relevance of The Idea of Canada, saying, "Canada allows you to be patriotic and not to be nationalist."Credits:Composer Christos HatzisProducer Steve WadhamsAudio engineers Laurence Stevenson and Rod Crocker.

"Canada can either now lose complete control — which it almost has, economically, spiritually and a few other things — or it can get itself together," said artist Joyce Wieland in 1971. In the 60s and 70s, the artist painted, sculpted and stitched the Canadian flag and our sense of national identity. Her art called on the need to preserve its distinctness from the United States. Now, a quarter century after her death, the artist's work and words form a clarion call. *This episode originally aired on Sept. 12, 2022.

"We come from the sea. It's not a memory. It's a feeling. It's in our DNA," Joan Jonas told IDEAS producer Mary Lynk at her home in Nova Scotia. The arts icon, now 88, has been celebrated for her work since the late 1960s. She splits her time between a Soho loft in NYC, and the "magical landscape" of Cape Breton, where she can be by her muse: the ocean. In 2024, she received her crowning recognition in the U.S., when New York's Museum of Modern Art organized a major retrospective of her work. Part of Jonas' MoMA retrospective called Moving Off the Land II has been acquired by the National Gallery of Canada and the Art Gallery of Nova Scotia. The exhibit will tour across Canada this summer, beginning in Cape Breton.

Even in the name of love, we can justify hatred, even murder, of the other. But why do we hate others? Scholars have identified a list of 10 reasons why one group may hate another group. They also have suggestions on how to break the cycle of hate. Guests in this episode are scholars from the Canadian Institute for Advanced Research (CIFAR):Prerna Singh, professor of political science, Brown University, U.S.Victoria Esses, professor of psychology, Western University, London, Ontario Stephen Reicher, professor of social psychology, University of St. Andrews, Scotland

Fifty years ago, the movie Jaws put sharks on our radar in a very real way. It broke box office records and tapped into an underlying fear of sharks and the unknown lurking in the ocean. Turns out, sharks were already developing a villainous reputation before Jaws. In this documentary, producer Molly Segal explores the long history people have with the ocean, and our tendency across cultures and times to create 'sea monsters' out of the depths of the ocean.

Champion hurdler Perdita Felicien has climbed to the summits of international glory throughout her track career, and endured the excruciating lows of defeat. Those peak experiences inform the talk she gave at Crows Theatre in Toronto, in which she parses the comparison of sport to life, and life to sport. In her words: "It isn't that sport is life exactly. It's that it reveals life. It's the part of life where we play with purpose. Where effort is visible. Where character is tested. Where failure is not final, just part of the arc. It's where we try. Fully. Openly. Without guarantee."

A groundbreaking study conducted in the wake of the Second World War by a group of scholars rocked the academic world when it was published in 1950 — but fell out of favour. Now a new generation of scholars is reviving the lessons of The Authoritarian Personality to understand who is drawn in by fascist propaganda.

There is a growing number of researchers who are 'forcibly displaced' worldwide. Thirty-four Canadian universities and colleges are currently hosting scholars who’ve left their jobs and homes to find safety. Scholars-in-exile from dozens of countries gathered at Carleton University in Ottawa to discuss ways to support free thinking and research whenever it is threatened.

From planting periwinkles on the graves of slaves, to the blues itself, the colour blue has been core to Black Americans’ pursuit of joy in the face of being dehumanized by slavery, argues Harvard professor Imani Perry. In her latest book, Black in Blues: How a Color Tells the Story of my People, she unpacks the deep, centuries-long connection between Black people and the colour blue, from the complex history of indigo dye to how the blues became a crowning achievement of Black American culture.

What happens to the land after a brutal wildfire? IDEAS visited St'át'imc territory near Lillooet, B.C., to follow land guardians and scientists from the Indigenous Ecology Lab at the University of British Columbia, as they document the effects of wildfires and chart a new future based on Indigenous approaches to healing and balancing an ecosystem. *This is part two of a two-part series.

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. IDEAS visited 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. *This is part one in a two-part series.Guests in this series:Chief Justin Kane, elected Chief of Ts'kw'aylaxw First Nation Michelle Edwards, Tmicw coordinator for the St'át'imc Chiefs Council and the former Chief of the communities of Sekw'el'was and Qu'iqten Sam Copeland, senior land guardian for the P'egp'ig'lha Council Luther Brigman, assistant land guardian for the P'egp'ig'lha Council Travis Peters, heritage supervisor and interim lands manager for Xwísten First Nation Gerald Michel, council member and the Lands Resource Liaison for Xwísten First Nation Denise Antoine, natural resource specialist for the P'egp'ig'lha CouncilDr. Jennifer Grenz, assistant professor in the department of forest resources management at the University of British Columbia.

In George Grant's famous 1965 essay, Lament for a Nation, the Red Tory philosopher argued that Canadian nationalism had died. He believed that when Canada was tied to the UK, the country was committed to a collective common good. But when it became integrated with the U.S., Grant says Canada abandoned this idea. Sixty years later, our relationship with the U.S. is being tested, igniting a rise in nationalism. PhD student Bryan Heystree finds hope in Grant's work and says there's valuable criticism worthy of our attention in the 21st century.

The 18th-century philosopher Adam Smith is often called “the father of economics,” and sometimes “the father of capitalism.” IDEAS contributor Matthew Lazin-Ryder examines how Smith’s name has been used and abused to both defend and attack free-market economics since his death.

When IDEAS contributor Sandra Bourque was diagnosed with ADHD in her early 50s, she was relieved. Finally, everything made sense to her. Bourque became obsessed with learning everything about how her brain worked. What she found was a mountain of information that focused on ADHD deficits and challenges, ways to "fit in better and be more normal." So Bourque became an ADHD coach so she could help others cut through the misinformation, focus on their strengths and learn how their brain actually worked. *This is part two in a two-part series called Myth of Normal.

Imagine a world without Mozart or Michelangelo, Einstein or Edison. Famous for their creativity, a "mysterious force" that psychiatrist and ADHD expert, Ed Hallowell, says is a commonality in neurodiverse people. Neurodiversity is a relatively new term, but the thinking behind it has been going on for a while. There’s increasing evidence that what we know today as Autism, ADHD, BipolarDisorder, Schizophrenia, and Dyslexia may have been a way for us to extend our species chances of survival. And yet the thinking around brain variations like ADHD is that it's a deficiency, something that needs to be fixed. Sandra Bourque's two-part series, The Myth of Normal traces the social and cultural response to neurodiversity and whether there's a way back to seeing this way of thinking as an advantage.

If you're someone who thinks reading is therapeutic, you aren’t alone. 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 episode, researchers Sara Haslam and Edmund King discuss the World War Ⅰ 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.

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.

There are three components that could end constitutional democracy as we know it, says scholar Peter L. Biro — fear and its weaponization, habituation which involves the consequence of not noticing, and the 'stupidification' of our minds and of our discourse. 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.
