    The Nature of the Sexes | Tomás Bogardus (with Stephen Kershnar)

    2026/02/22 | 1h 4 mins.
    Tomás Bogardus joins to discuss his book "The Nature of the Sexes" and argues for a reproductive-functional account of biological sex. According to Bogardus, males and females are defined by the reproductive function their bodies are structured to perform: producing sperm or eggs. Even when that function is not realized and no sperm or eggs are produced, a person’s sex remains the same, because it is grounded in biological organization. To defend this view, Bogardus considers intersex and DSD cases, critiques contextualist accounts that treat sex as domain-dependent, and argues for a unified meaning of “male” and “female.” The conversation later turns to whether sex is essential or changeable, as well as debates about pronouns, sports, and medical interventions for minors.

    God Is Not Praiseworthy | Stephen Kershnar and Nathan Bray

    2026/02/09 | 1h 4 mins.
    Brain in a Vat is back from hiatus with a deep dive into the philosophy of religion. Stephen Kershnar and Nathan Bray join us to ask whether God can be morally responsible and whether worship makes sense if God could not have done otherwise.

    The discussion begins with a thought experiment about gratitude and worship. If worship expresses praise for morally responsible action, can a perfectly good God deserve it at all? Kershnar and Bray argue that divine perfection may undermine responsibility rather than secure it.

    From there, Kershnar and Bray explore compulsion, omnibenevolence, and free will. Along the way, we discuss moral saints, chess computers, Frankfurt-style cases, Patty Hearst, and the costs these arguments impose on traditional theism.

    We would love to hear your thoughts. Is worship grounded in gratitude, awe, or something else entirely? And does God need moral responsibility to be worthy of it?

    Facial Distortions and Prosopometamorphopsia | Brad Duchaine (Rebroadcast)

    2025/11/09 | 1h 1 mins.
    In this special episode of Brain in a Vat, Brad Duchaine from the Psychological and Brain Sciences Department at Dartmouth discusses prosopometamorphopsia (PMO) – a condition where individuals see distorted faces.

    The episode explores various manifestations of PMO, including seeing demonic features, dragons, or entirely different faces, and distinguishes it from prosopagnosia (face blindness). It delves into the neurological basis of PMO, touching upon structural and functional differences in the brains of those affected.

    We discuss the significant impact PMO and prosopagnosia have on individuals' social interactions and quality of life, as well as potential management techniques such as using glasses or colored lights to reduce distortions.
