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.

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.
