How to Defeat Authoritarianism | Augusto Pinochet's Chile

As we continue our series on authoritarianism, host Nahlah Ayed and panelists explore Pinochet’s popularity with centre-right Western leaders, the referendum that removed him from power, and the story of his eventual arrest and trial.

How new fascism operates

Historian Marci Shore doesn't hesitate to use the word 'fascism' to describe the present moment. The former Yale professor left the U.S. after President Trump was re-elected. She now teaches at the University of Toronto and tells her students why "we shouldn't fetishize" the term. Shore argues concepts and terminologies born from history like fascism is how we process the world, but it's critical we allow for today's nuances and differences. This podcast includes Marci Shore in conversation with IDEAS host Nahlah Ayed and Shore's lecture “Thoughts From a Post Truth World," part of the series “Democracy in Peril: A Way Forward Against Authoritarianism," organized by the University of Manitoba, and the Canadian Museum for Human Rights in Winnipeg. Marci Shore is Chair of European Intellectual History at the Munk School of Global Affairs & Public Policy at the University of Toronto.

Birth is the story of us all. But do you know its history?

Not everyone gives birth. But everyone is born. Yet we rarely talk about the history of childbirth. So author Lucy Inglis researched its bloody, triumphant, political past. Her book Born: A History of Childbirth argues that birth has a deep global history that proves it has always been a highwire act, shaped by both nature and culture. IDEAS explores the visceral, intimate realities of childbirth that have always been in evidence. *This episode originally aired on Jan. 22, 2026.

The student who took off her shirt for women's rights

Nineteen-year-old Gwen Jacob is just trying to catch a breeze when she goes topless during a 1991 heat wave. But after being cat-called and arrested, her simple attempt to stay cool turns into a statement. And when she refuses to pay her fine, she ends up in a court battle that triggers a nationwide debate about sexism, safety and control over women’s bodies.
