    From the archive: Varieties of childhood
    2026/07/31
    Hi friends! We're taking a bit of a summer pause. We'll be back soon—in the meanwhile, enjoy this listener favorite from our archives! ----- [originally aired July 10, 2025] Childhood is a special time, a strange time. Children are adored and catered to—they're given their own menus and bedrooms. They're considered delicate and precious, and so we cushion them from every imaginable risk. Kids are encouraged to play, of course—but very often it's under the watchful eye of anxious adults. This, anyway, is how childhood looks in much of the United States today. But is this the way childhood looks everywhere? Is this the way human childhoods have always been? My guests today are Dr. Dorsa Amir and Dr. Sheina Lew-Levy. Dorsa is an Assistant Professor of Psychology & Neuroscience at Duke University, where she runs the Mind and Culture Lab. Sheina is an Associate Professor of Psychology at Durham University in the UK, where she co-directs the Forager Child Studies research group. Both Sheina and Dorsa have spent much of their careers thinking about how childhoods differ across cultures—and why. In this conversation, I talk with Dorsa and Sheina about their fieldwork with indigenous groups in Ecuador and the Congo, respectively. We discuss the different ways that childhood differs in these places—for instance, in terms of parents' attitudes toward risk, in terms of the social structures and activities in which kids are embedded, and in terms of the freedom that children are granted. We discuss developmental psychology's "WEIRD problem." We talk about the quasi-autonomous cultures that children create among themselves—sometimes called "peer cultures"—and discuss how these kid-driven cultures end up shaping and benefit the larger community. Along the way, we touch on adult supremacy, adverse childhood experiences, walking the forest and climbing papaya trees, parenting norms, ding dong ditch and "nananabooboo", the pioneering work of the folklorists Iona and Peter Opie, teaching, toys, and the enduring question of what childhood is for. Alright friends, lots to think about here. On to my conversation with Sheina Lew-Levy and Dorsa Amir. Enjoy! A transcript of this episode is available here.

    From the archive: Philosophers on psychedelics
    2026/07/17
    Hi friends! We're taking a bit of a summer pause. We will be back soon—in the meanwhile, enjoy this listener favorite from our archives! ----- [originally aired May 14, 2025] Some call it the "psychedelic renaissance." In the last decade or so, interest in psychedelic drugs has surged—and not just among Silicon Valley types and psychiatrists and neuroscientists. It's also surged among a stereotypically soberer crowd: academic philosophers. The reasons are clear. With their varied and sometimes transformative effects, psychedelics raise ethical questions, epistemological questions, metaphysical questions, questions about the nature of experience and the nature of the mind. My guest today is Dr. Chris Letheby. Chris is a philosopher of cognitive science at the University of Western Australia and the author of the 2021 book, Philosophy of Psychedelics. Here, Chris and I talk about the so-called classic psychedelics—LSD, psilocybin, ayahuasca, and others—and how interest in them has gone through three distinct waves. We discuss the effects that these substances seem to have, in particular their capacity to treat certain psychiatric conditions and their tendency to induce "mystical-like" experiences. We consider the idea that psychedelics might serve as agents of moral enhancement. And we dig into the psychological and neural mechanisms by which psychedelics seem to have their diverse—and often salutary—effects. Along the way, we talk about ontological shock, comforting delusions, brain plasticity, unselfing, microdosing, placebo effects and adverse effects, physicalism and idealism, the REBUS model, environmental virtues, plant consciousness, meditation, and much more. Maybe this is obvious but this episode is not just for the seasoned psychonauts out there. Whatever your personal experience with these substances, they offer a distinctive window into the mind—a new way of grappling with big questions. Perhaps this much is also obvious but we're not encouraging or endorsing the use of psychedelics here—just offering a little fuel for your intellectual fires! Alright friends, on to my conversation w/ Dr. Chris Letheby. Enjoy! A transcript of this episode is available here.

  • The origins of Darwin's ideas

    The origins of Darwin's ideas
    2026/07/03
    No discipline, no sphere of intellectual life, has been untouched by the work of Charles Darwin. He died in 1882 but his ideas are very much alive; they're now central to how we understand the natural world, the human mind, non-human minds, plants, biogeography, morality and emotion, culture, language, and more. But where did his ideas come from? How did they grow out of his travels, his social circle, his hobbies, his particular cast of mind? My guest today is Dr. Janet Browne. Janet is Professor Emerita at Harvard University in the department of the History of Science. She is perhaps best known for her widely acclaimed two-volume biography of Charles Darwin. And she has now published an updated and abridged single-volume version. Here, Janet and I talk about Darwin's life and ideas. We pick up the story during his travels on the Beagle, a five-year voyage that laid the foundation for the rest of his career. We talk about what he was reading, what he was seeing, and how these experiences helped form his most influential work, On the Origin of Species. We discuss Darwin's style as a thinker, as a naturalist, as a writer, and as an experimentalist. We touch on his relationships with contemporaries like Charles Lyell and Alfred Russel Wallace. And we consider his long—and often overlooked—engagements with pigeons, barnacles, plants, and worms. I greatly enjoyed Janet's two-volume biography of Darwin, and I enjoyed this new single-volume edition just as much. So if this episode sparks your interest, I heartily recommend that you check these books out. Alright friends, on to my conversation with Dr. Janet Browne. Enjoy! Notes 3:30 – Darwin's autobiography is available here. All of Darwin's letters are readable (and searchable) at the Darwin Correspondence Project. 11:00 – Darwin's account of his five-year stint on the HMS Beagle can be found in his book, The Voyage of the Beagle. 17:00 – Charles Lyell's Principles of Geology (Vol. 1). 27:00 – For a recently published history of Lamarck and his ideas, see here. 31:00 – For more on Darwin's interest in pigeons and pigeon breeding, see here. 34:00 – For more on Darwin's barnacle studies, see here. 40:00 – For a brief account of the relationship between Wallace and Darwin, see Dr. Browne's article here. 44:00 – Alfred Russel Wallace's The Malay Archipelago is here. Wallace's own essay on natural selection, sent to Darwin before the publication of On the Origin of Species, is here. The proceedings in which Darwin's and Wallace's first papers on natural selection appeared together. 53:00 – For a modern treatment of the concept of sexual selection, see here. For an online version of Darwin's The Descent of Man, see here. For a recent collection of essays on Darwin's Descent, including one by Dr. Browne, see here. 58:00 – Darwin's The Expression of the Emotions in Man and Animals. 1:03:00 – Darwin's short article, 'A biographical sketch of an infant.' 1:08:00 – Darwin's The Power of Movement in Plants. For more about Darwin's last book, The Formation of Vegetable Mould, through the Action of Worms, see here. For more about Darwin's "root-brain hypothesis," see our earlier episode. 1:14:00 – For more on Darwin's theory of gemmules and pangenesis, see here. 1:15:00 – For more on Darwin's substantial archive, see here.
