The potato and the Irish Famine of 1845 will forever be linked. But what's often overlooked is how deeply connected the potato was to British colonial policies during that time. To Britain it was a symbol of Irish backwardness. In the book Rot, a new history of Ireland's Great Famine is revealed, showing how the British Empire caused the infamous disaster. Author and historian Padraic X Scanlan paints a complex and compelling picture of the Irish Famine of 1845, in which the potato — and the blight — played but a part in a broader story of colonialism, capitalism, and collapse.

We are all born. Birth is the story of us all. So why aren’t we more curious about its history? That's what historian Lucy Inglis wanted to know. She's spent 15 years researching birth — around the globe, and across the centuries. “When you go into labour, you are a ship on the sea," says Inglis, referring to an ancient Assyrian chant acknowledging the physical perils of giving birth. While medical advances and greater freedom of choice inform birth in countries like England and Canada today, 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.

What's the secret weapon to make political change happen? It's not a trick question, it's simple: perseverance, says BBC Reith Lecturer Rutger Bregman. The historian envisions a "realist utopia" in this lecture and asks listeners to join what he describes as a “conspiracy of decency" — a world where Universal Basic Income, fairer taxation and stronger tech regulation can start to build a more just and resilient future. A great movement Bregman says needs radicals who push the fringes but also moderates "who are actually able to make compromises and get things done." There's a role for everyone just find a small group of committed, determined, morally-serious people and "then you can move mountains."

We live in an "age of immorality," argues historian and author Rutger Bregman. "The moral rot runs deep across elite institutions of every stripe," Bregman says in his first BBC Reith Lecture. His series of lectures describes why he is calling for a moral revolution to counter the culture of cynicism and un-seriousness among global elites. Bregman says history has proven how small determined groups have catalysed profound moral change, and that legacy should be an inspirational guide for all of us today. IDEAS is featuring lectures from the BBC Reith Lectures, this is the first episode.

This podcast seeks answers to the question. If you are left-handed then you are part of the 10 per cent of humankind that detested craft time in elementary school that involved scissors. Left-handed people often have to accommodate their difference in our dominant right-handed world. But that can get tricky if you are training to be a surgeon. Operating rooms and surgical instruments become big obstacles for left-handed people as IDEAS contributor Mark Dance finds out in his documentary exploring the history and mystery of left-handers. *This episode originally aired on May 6, 2022.

Think of science's most momentous developments in the 20th century — Einstein’s theory of relativity, quantum physics, finding evidence of black holes. If you trace the chain of discoveries that led to these breakthroughs back far enough, you’ll end up with the Italian astronomer and physicist Galileo Galilei. Theoretical physicist Carlo Rovelli says we can learn a lot from Galileo today. He explains how 400 years ago, the renowned inventor was discovering new facts about the Universe to understand ourselves better — and so are we.

"This is a hopeless situation but we are not helpless." This is what drives Sudanese journalist Yousra Elbagir's reporting on her homeland's forgotten war. She uses what she calls "human reporting" to let the world know Sudan is more than conflict and suffering. "Sudanese generosity is our lifeblood. That's what's keeping us alive right now. We are actually surviving in forced starvation through generosity and kindness and care."

Yousra Elbagir delivered the 2025 Stursberg Foreign Correspondents Lecture at Carleton University. She spoke to host Nahlah Ayed about her work and her lecture: Human reporting from Sudan and beyond — a remedy for selective empathy?

"Those who remember the disappeared would also disappear." Under dictator Bashar al-Assad, grieving publicly in Syria was punishable. Now the silenced stories of lost loved ones are emerging and there are public spaces to grieve. Syrian architect Ammar Azzouz's friend and colleague Taher Al Sebai was killed on his street in 2011. After 14 years in exile, Azzouz returned home and says it's not just a right but "a duty to remember." IDEAS hears about Azzouz's classmate from architecture school, the lives of a father, a brother, and a singer who became the voice of the revolution.

Prior to riding horses, no one wore pants. There's a lot to thank horses for in our daily lives. From the Hollywood motion picture to life-saving vaccines for diphtheria and tetanus. Historian Timothy Winegard argues horses are intertwined in our own history to the point that we overlook their importance. His research explains how they shaped societies, economies and cultures. Without us, horses would be nowhere, and vice versa. It was a partnership — our brains and their braun — that truly changed the world. *This episode originally aired on Sept. 10, 2024.

It's getting pretty difficult to read any article online without a paywall in the way. What happened to the internet's great promise to democratize knowledge? On an individual basis, artists, writers and scientists can create without fear of theft thanks to copyright laws. But in practice copyright laws set up barriers, stifle production and prevent equal access to art and research. In this podcast, producer Naheed Mustafa explores the fate of “open access” — all in the ever-expanding universe of copyright laws, paywalls and old-fashioned bureaucratic sludge.

Guests in this podcast:

John Willinsky is emeritus professor of education at Stanford University with an appointment at Simon Fraser University.

Lokesh Vyas is pursuing a PhD at Sciences Po in Paris working on the history of international copyright law.

Thea Lim is a Toronto-based novelist, creative writing teacher, and cultural writer focussing on the intersection of power, art and personhood, and technology.

We gorge ourselves on the internet, smartphones, social media, information overload — all of it constantly sap us of our emotional and intellectual vitality. Authors Pico Iyer and Jonathan Haidt argue it's vital we disconnect from our addictive online world to pursue a fulfilling, and richer life. By curtailing the noise of technology, media and other worldly distractions there's space to reconnect with the things that matter. "Humans were never designed to live at a pace determined by machines. The only way we could begin to do that is by becoming machines ourselves," says Iyer.

Pico Iyer and Jonathan Haidt were two of the marquee speakers at the 2025 Aspen Ideas Festival. The theme this year was 'What Makes Life Good.'
