Making Sense of Existential Threat & Nuclear War
In this episode, we examine the topic of existential threat, focusing in particular on the subject of nuclear war.
Sam opens the discussion by emphasizing the gravity of our ability to destroy life as we know it at any moment, and how shocking it is that nearly all of us perpetually ignore this fact. Philosopher Nick Bostrom expands on this idea by explaining how developing technologies like DNA synthesis could make humanity more vulnerable to malicious actors.
Sam and historian Fred Kaplan then guide us through a hypothetical timeline of events following a nuclear first strike, highlighting the flaws in the concept of nuclear deterrence. Former Defense Secretary William J. Perry echoes these concerns, painting a grim picture of his "nuclear nightmare" scenario: a nuclear terrorist attack.
Zooming out, Toby Ord outlines each potential extinction-level threat, and why he believes that, between all of them, we face a one in six chance of witnessing the downfall of our species. Our episode ends on a cautiously optimistic note, however, as Yuval Noah Harari shares his thoughts on "global myth-making" and its potential role in helping us navigate through these perilous times.

Making Sense of Belief and Unbelief
In this episode, we examine a series of Sam’s conversations centered around religion, atheism, and the power of belief.
First, we hear the stories of three guests who have fled their respective oppressive religious organizations. We begin with Sarah Haider, founder of the advocacy group Ex-Muslims of North America, who details how her encounters with militant atheists catalyzed her journey to secularism. Then our narrator, Megan Phelps-Roper, walks us through her story of abandoning the Westboro Baptist Church. Finally, Yasmine Mohammed presents her harrowing account of escaping fundamentalist Islamism and Sam’s role in inspiring her public advocacy work.
We then tackle the concept of belief more broadly, diving into Sam’s understanding of atheism and what sets it apart from the views of other atheist thinkers like Matt Dillahunty and Richard Dawkins. We also revisit an infamous conversation between Sam and Jordan Peterson, wherein they attempt to come to some universal definition of the word “truth.”
The episode concludes with two Q&A portions from life events in which Sam addresses some real concerns about purpose and meaning in the absence of religion.
