A century after Henry Ford helped popularize the five-day, 40-hour week, could working 32 hours be next? Supporters say shorter weeks can improve well-being without sacrificing productivity, especially as AI would make workers more efficient. Others warn it would strain industries that require continuous staffing and force Americans to rethink everything from school and healthcare schedules to expectations of around-the-clock availability. We debate: Is America Ready for a Four-Day Work Week?

Arguing Yes: Juliet Schor, Economist and Sociologist at Boston College

Arguing No: Joanne Lipman, Bestselling Author, Journalist, and Former Media Executive

Capitalism has long been credited with driving innovation and prosperity, yet many Americans increasingly believe the system is no longer working for them. Is the problem capitalism itself or the policies surrounding it? In this debate, an entrepreneur and venture capitalist faces a prominent economist with a competing vision to examine inequality, economic opportunity, and the future of the American economy. Now we debate: Is Capitalism Broken?

Arguing Yes: Nick Hanauer, Entrepreneur and Venture Capitalist

Arguing No: Jason Furman, Former Chairman of the Council of Economic Advisers; Professor at Harvard University’s John F. Kennedy School of Government

The dangers of climate change are “no longer over the horizon.” Humanity may soon pass the “point of no return.” These are the phrases U.N. Secretary-General Antonio Guterres used to describe what he called an “utterly inadequate” global response to rising temperatures. But if we were to decisively act and restructure our global economy with the climate in mind, who would shoulder the burden? Or should our collective focus orient more toward humans’ capacity for adaptation? This ethical conundrum is at the crux of this week's debate, originally broadcast in July 2022.

Arguing Yes:

Bjorn Lomborg, Author of the Bestsellers "Cool It" and "The Skeptical Environmentalist"; Director of the Copenhagen Consensus Center

Matthew Kahn, Provost Professor of Economics and Spatial Sciences at the University of Southern California

Arguing No:

Michele Wucker, Economic Policy Expert & Founder of Gray Rhino & Company

Near-death experiences have long challenged our understanding of consciousness and mortality. Some who come close to death report leaving their bodies, encountering vivid visions, or feeling profound peace. Are these experiences evidence that consciousness can survive death — or can they be explained by what happens in a dying brain? This 2014 debate is one we're still thinking about today. We ask whether science can reveal what, if anything, awaits us after we die.

Arguing Yes:

Eben Alexander, Former Neurosurgeon; Author of "Proof of Heaven"

Raymond Moody, Medical Doctor; Author of "Life After Life"

Arguing No:

Sean Carroll, Physicist & Writer

Steven Novella, Academic Neurologist at the Yale School of Medicine
