How the invention of the book shaped humanity

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.'

Holmes Rolston III began his career as a Presbyterian minister. But his love of the natural world — and his belief in evolution — didn't sit well with his congregation. He was ultimately fired. The late philosopher spent much of his career working to bridge the gap between science and religion because he said "the future of Earth depends on it." Rolston is the pioneer of environmental ethics, a turning point in philosophy. His ultimate goal was to define the moral worth of the planet. Rolston died in 2025 at the age of 92. In this episode, IDEAS explores his legacy and the continuing resonance of his work.Guests in this documentary:Christopher Preston is a professor of environmental philosophy at the University of Montana, Missoula.

Maria Chapdelaine: A Tale of French Canada is one of the most widely read works of fiction ever written in French. It's considered the world's highest-selling French book.

Translated into over 20 languages, the book's character Maria and her story has inspired four film versions, several plays, an opera, and even a pop song.Contributor Catherine Annau examines the many lives that Maria Chapdelaine has lived, and continues to live. *This episode originally aired on Feb. 4, 2024.

Would you 'doo-be-doo' if you know it would help bridge divides? Try vocal improvisation — singing sounds, rhythms and melodies. PhD candidate Erwan Noblet teaches the practice and says it's a great way to open up and connect at another level being together. He believes the human voice has the power to communicate creatively when it's released from everyday verbal tasks. We asked three former politicians from different political parties to communicate through vocalization, without words. Their conversation may inspire you to take on vocal improv.*This episode is part of our ongoing series Ideas in the Trenches, which showcases fascinating new work by Canadian PhD students. 

What do you get when you take some of the classic Enlightenment values like reason, fairness, and justice, and substitute them with opinion, privilege and power: The Dark Enlightenment — a movement that is a deliberate oxymoron with a vision to dump democracy and replace it with start-up cities run by CEOs. American blogger Curtis Yarvin, also known by the pen name Mencius Moldbug, is the founder of this movement that advocates for the return of traditional hierarchical societies and monarchy-like governance.

Bioethicist Arthur Schafer has thought a lot about life and death. He's helped shape policy on medically assisted death (MAID) in Canada. The philosophy professor argues that an ideal end-of-life legislation would respect individual choice and the wishes of individuals to die according to their own values. "The best ethical argument is that patient autonomy is a fundamental value," Schafer told host Nahlah Ayed. He discusses the role of philosophy in addressing complex ethical dilemmas confronting individuals, and society as a whole. *This episode originally aired on May 16, 2024.

If we weren't so used to having books, we would think of them as a "miracle." That's how historian Irene Vallegoviews what she says is humankind's greatest and most influential invention: the book. "With their help, humanity has undergone an extraordinary acceleration of history, development, and progress," she tells host Nahlah Ayed. Vallego has traced written texts back to their earliest origins and she's written a book of her own, Papyrus: The Invention of Books in the Ancient World.  

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.
