  • What is memory for?

    What is memory for?
    Nov 20 2025
    Everyone loves a good evolutionary puzzle. Why do we have appendices? Why do we dream? Why do we blush? At first glance, memory would not be in this category. It's clearly useful to remember stuff, after all—to know where to find food, to remember your mistakes so you don't repeat them, to recall who's friendly and who's fierce. In fact, though, certain aspects of memory—when you hold them up to the light—turn out to be quite puzzling indeed. My guests today are Dr. Ali Boyle and Dr. Johannes Mahr. Ali is a philosopher at the London School of Economics (LSE); Johannes is a philosopher at York University, in Toronto. Both have written extensively about the functions of memory, and, in particular, about the functions of episodic memory—that capacity for calling up specific events and experiences from our own lives. Here, Ali, Johannes and I lay out the textbook taxonomy of memory, and discuss how episodic memory has drawn the lion's share of philosophical interest. We pick apart the relationship between episodic memory and another major type of long-term memory, semantic memory. We sketch a range of different accounts of the evolved functions of episodic memory, including Johannes's proposal that episodic memory serves communication and Ali's proposal that it fuels semantic memory. And, finally, we consider what this all means for our understanding of memory in children and in animals. Along the way, we touch on Highly Superior Autobiographical Memory, infantile amnesia, evidential systems in language, imagination, "simulationist" theories of episodic memory, what it feels like to remember, collective memory, the hippocampus, cryptomnesia, and the cow's digestive system as a metaphor for memory.

  • Of breeds and brains

    Of breeds and brains
    Nov 6 2025
    It's hard to say exactly when, but some tens of thousands of years ago, our best friends were born. I'm referring, of course, to dogs. This didn't happen overnight—it was a long process. And it not only changed how those canids behaved and what they looked like, it also changed their brains. As wolves gave way to proto-dogs, and proto-dogs gave way to dingoes and dalmatians and Dobermanns and all the rest, their brains have continued to change. What can we learn from this singular saga? What does it tell us about dogs, about domestication, and about brains? My guest today is Dr. Erin Hecht. Erin is an Assistant Professor in the Department of Human Evolutionary Biology at Harvard, where she directs the Canine Brains Project. Here Erin and I talk about how dogs are the most anatomically diverse species on the planet—and how their brains are no exception. We sketch the different waves in the dog domestication saga and discuss scenarios for how that saga got underway. We talk about how brains change as they get bigger and about how they change during domestication. We discuss a recent study by Erin and colleagues comparing the brains of modern dogs with the brains of pre-modern dogs like village dogs and New Guinea singing dogs. We also talk about a new study from Erin's lab finding that domestic dogs share with humans a key language-related structure. Along the way we talk about the Russian Farm Fox experiment, the stereotype of the gentle giant, the left lateralization of language, the respiratory condition known as BOAS, the dog personality inventory known as C-BARQ, the limitations of the idea of a "domestication syndrome," and the puppy kidnapping hypothesis. Longtime listeners will recall that we had Erin on the show to talk about her work on fermentation and brain evolution. Given how much fun we had with that one, it was only a matter of time before we had her back to talk about her main line of research on dog brains. So here you go friends—hope you enjoy it! Notes 4:30 – For one recent study of the early domestication of dogs, see here. For a review of leading hypotheses about what drove the wolf-to-dog transition, see here. 13:00 – For Dr. Hecht's initial 2019 study of brain variation across domestic dog breeds, see here. 20:00 – For a classic paper on the neurodevelopmental scaling by Dr. Barbara Finlay and colleagues, see here. 23:00 – For more of Dr. Hecht's work on neurodevelopmental scaling laws as they apply to dogs, see here.

  • Monsters and their makers

    Monsters and their makers
    Oct 23 2025
    It seems we've always had monsters among us. We've long been enthralled by dragons and giants, by the likes of Frankenstein and Godzilla and Dracula, by witches and werewolves and countless others. They roam our maps and creation myths; they crop up in our dreams, in our children's books, in our political rhetoric. Where do these beings spring from? What do they do for us? How have they changed over time? And, ultimately, what do our monsters say about their makers? My guests today are Dr. Natalie Lawrence and Dr. Surekha Davies. Both are historians of science and authors of recent books on monsters: Natalie's book is Enchanted creatures: Our monsters and their meanings. Surekha's book is Humans: A monstrous history. Here, Surekha, Natalie, and I talk about monsters as category breakers and boundary walkers—and about how monstrosity is in the eye of the beholder. We walk through a menagerie of monsters—from the apocryphal blemmyes of old travelogues, to a hairy-faced girl in 16th century France, to the figure of Caliban in The Tempest. We discuss the psychological and cultural forces that generate monsters. And we talk about whether anyone would want to live in a world without them. Along the way, we touch on the "monstrification" of social groups; psychoanalysis; our primal fear of snakes; curiosity cabinets; therianthropes and the Cave of the Three Brothers; the relationship between monstrosity and geography; our long fascination with so-called monstrous births; the Muppet Show; dinosaurs and sea creatures; and the question of what monsters might do for children in particular. Alright friends, it's the monstrous season and this is a fun one to help you celebrate. Enjoy! Notes 3:00 – Grendel's mother has often been a subject of critical discussion and adaptation. See, for instance, the 2018 novel, The Mere Wife. 12:30 – For a classic history-of-science treatment of "wonders" (including monsters) and our conceptions of nature, see here. 18:30 – For those unfamiliar with muppets, an episode of the Muppet Show, which premiered in 1976. 24:00 – The blemmyes were often the subjects of illustration—for examples, see here. 26:00 – For more on Sir Walter Raleigh and the blemmyes, see Dr. Davies' recent newsletter post. 29:00 – One example of monsters at the margins of maps can be seen in the Psalter World Map. 32:00 – For more on Cave of the Trois-Frères and the Sorcerer, see here. 34:00 – For more on shamanism, see our recent episode with Manvir Singh. 37:00 – Therianthropes are relatively rare in cave art, but have nonetheless been widely discussed. For an example, see here. 39:00 – For more on Antonietta Gonsalvus and her family, including examples of how she was represented in paintings of the era, see here. 45:00 – The trope of monsters in creation stories is often called "chaoskampf." 47:00 – The meanings of Medusa have been widely discussed and debated. See here for an example. 52:00 – For more about Caliban, and the racial and colonial dimensions of the Tempest, see here. 57:00 – The Steinbeck quote comes from his book, The Log from 'The Sea of Cortez.'
