Episode's summary

More than 2,000 years ago, someone sat down and wrote a travel bucket list for the ancient world — suggesting must-see places that we now call The Seven Wonders of the World. It was kind of a Lonely Planet guide of its time, and included the Pyramid of Giza, the Hanging Gardens of Babylon, the lighthouse of Alexandria, and the Temple of Artemis, among others. Historian Bettany Hughes brings monuments and archaeological discoveries back to life in her book,"The Seven Wonders of the Ancient World." *This episode originally aired on Nov. 6, 2024.

How the Moon shaped humanity — and defined life on Earth

This episode explores the profound physical, biological, and evolutionary impact of the moon on Earth, from its origin via the giant-impact hypothesis to its role in stabilizing Earth's climate and driving life from water to land. The discussion traces how the moon's gravitational influence shaped human civilization through lunar calendars and timekeeping. Furthermore, the episode examines the evolving human perception of the moon, moving from ancient mythological views to the scientific revolutions sparked by Galileo and Copernicus. Through accounts of the Apollo missions and astronaut Charlie Duke, the narrative explores how lunar exploration transformed the moon from a mysterious orb into a physical world, ultimately redirecting our reverence toward the fragility and interconnectedness of Earth itself.

Tech billionaires are betting on a coming Apocalypse

Host Nala Ayyad interviews authors Astra Taylor and Naomi Klein about their book, 'End Times Fascism and the Fight for a Living World.' The discussion explores how modern fascism differs from 20th-century versions by embracing an 'Armageddon complex' driven by tech billionaires, religious extremists, and ethno-nationalists. The conversation examines the rise of 'tech fascism,' where elites leverage AI and ideologies of transcendence to rationalize environmental destruction. The authors contrast this with the concept of 'doikheit' or 'hereness,' advocating for a ferocious defense of our existing communities, bodies, and planet through messy, imperfect collaborations.

Are Alberta’s separatists guilty of 'moral treason'?

In this episode of Ideas, host Nala Ayyad interviews security expert Patrick Lennox about the potential for Alberta separatism and its links to foreign interference. Lennox argues that the movement's rhetoric aligns with a playbook used by authoritarian regimes like Vladimir Putin's to destabilize liberal democracies through disinformation. Lennox details how far-right ideologies, Christian nationalism, and the influence of American political actors could destabilize Canadian democracy. The discussion explores the risks of democratic erosion, drawing parallels to Brexit and the 'paradox of tolerance,' while weighing the impact of internal discord against external threats on Canada's national unity.

What draws a new immigrant to Quebec separatism?

This episode explores the diverging visions of sovereignty and identity in Quebec and Wales. It contrasts the inclusive, multicultural approach of Québec solidaire with more identitarian models, illustrated through the personal journey of Aisha Issa, an immigrant who found belonging within the Quebec independence movement. The narrative further examines themes of linguistic suppression and historical rebellion, detailing the impact of the 'Welsh Knot' on the Welsh language and the enduring legacy of figures like Owen Glyndŵr. The discussion concludes by addressing the modern political divides in Wales and the critical importance of the French language to Quebec's cultural survival.
