    Can Torture Be Justified? | Stephen Kershnar

    2026/05/17 | 58 mins.
    We welcome back Stephen Kershnar to discuss the ethics of torture. Kershnar argues that some criminals deserve torture because severe wrongdoing can cause a person to forfeit protections against extreme punishment. He critiques the idea that there are moral constraints the state must never cross.

    The dialogue also examines objections to torture concerning human dignity, bodily integrity, and the dangers of granting the state such power.

    A World Without Scarcity | Steven Kotler

    2026/05/06 | 59 mins.
    What happens to human beings in a world without scarcity? If all our needs were met, would we actually be better off? Will technological progress lead to utopia or collapse?

    Humans are living through massive improvements in material conditions. More people have access to food, energy, and technology than ever before. Steven Kotler examines what this kind of abundance does to us. It may support a more comfortable life, but it can also erode the conditions that sustain a sense of purpose.

    We also discuss how attention and identity are being affected by technological progress. As AI systems take on more optimization and decision-making, the role of human thought may change, raising questions about what remains distinctly human in how we engage with the world.

    Living with Adversity | David Benatar

    2026/05/06 | 55 mins.
    What does it mean to live with adversity? How ought we respond to the suffering of others? How can we adapt to hardship?

    Adversity is a universal experience. Nearly everyone, at some point, faces physical, psychological, or social challenges, and yet suffering often goes unnoticed.

    David Benatar joins us to discuss these questions on the human condition, provoked by his book 'Living with Adversity,' a collection of personal accounts of suffering.

    Risky Storytelling | Kevin Allison

    2026/05/06 | 1h 3 mins.
    Kevin Allison, creator of the RISK! podcast, recounts a high school prank at an all-boys Jesuit school in 1986. After a crush teased him by repeatedly spitting on him, Kevin later mailed him a sealed container of feces labeled “enjoy the cookies.”

    In retelling the story, Kevin considers how the prank mixes humiliation and a possible form of intimacy, situated within his experience of growing up gay under Catholic doctrine. For Kevin, telling such stories has become an opportunity for self-reflection.

    Beyond this, Kevin argues that sharing what is usually considered “unmentionable” can create a distinct form of connection: moments of vulnerability tend to draw listeners in rather than push them away. Thus, the points of greatest risk are often where an audience leans in most.

    Chapters:
    [00:00] The Mailing Feces Prank
    [12:49] Why the "Unmentionable" Matters
    [14:20] Coming Out Under Catholicism
    [18:09] Starting RISK!
    [23:02] Teaching Storytelling
    [35:41] Revisiting Old Stories
    [42:22] Audience Backlash
    [47:36] What are "Safe Spaces"
    [56:09] How Memory Alters a Story
    [01:03:29] Closing Remarks

    Free Speech, Hate Speech, and Mental Health | Chloe Carmichael

    2026/03/22 | 1h 2 mins.
    Clinical psychologist Chloe Carmichael, author of "Can I Say That?," examines how free expression relates to psychological well-being and social trust. Carmichael argues that suppressing disagreement drives resentment and misperception, rather than resolving conflict. She also scrutinizes the role of safe spaces, the spread of therapeutic language, and what limits on speech might be justified in public versus private life.
