    In search of names
    Dec 18 2025
    Alright, friends—we've come to the end of the 2025 run of Many Minds! Our final episode of the year is an audio essay by yours truly. This is a classic format for the show, one that we only do every so often. Today's essay is about names. It's about the question of whether animals have something like names for each other. And it's also about a deeper question: What even is a name? How do humans use names? How does the historical and ethnographic record kind of complicate our everyday understanding of what names are. I had a lot of fun putting this together, and do I hope you enjoy it. Now, the holiday season is a time when people might be shopping around for new podcasts to listen to. That makes it a great time to recommend us to your friends and family and colleagues. You can think of it has an especially thoughtful gift, one that's absolutely free, and that keeps on giving throughout the year. Speaking of gifts, as an addendum to this episode you'll find a little stocking stuffer after the credits. It's a reading of a poem that figures prominently in today's essay. Without further ado, here is my essay—'In search of names.' Enjoy! Notes: A text version of this essay will be published shortly. Notes 2:00 – The text of, 'The Naming of Cats,' by T.S. Eliot is here. See also the full collection, Old Possum's Book of Practical Cats. The lines about cats' taste preferences and cats having different kinds of minds comes from another poem in the collection, 'The Ad-Dressing of Cats.' 3:00 – The 2019 study finding that cats know their names, and the 2022 study showing that cats know the names of their friends. 4:00 – For an overview of research on dolphin "signature whistles," see here. 5:00 – For the 2024 study reporting name-like rumbles in elephants, see here. 6:00 – For the 2025 study reporting vocal labels for individuals in marmosets, see here.

  • The value of animal cultures

    The value of animal cultures
    Dec 4 2025
    Not long ago culture was considered rare in nature, maybe even uniquely human. But that's changed. We now know that the tree of life is buzzing with culture—and not just on a few lonely branches. Creatures great and small learn songs, migration routes, and feeding techniques from each other. Many species build up reservoirs of knowledge over generations. This has profound implications, not just for understanding of the natural world, but also for our efforts to protect it. My guest today is Dr. Philippa Brakes. Philippa is an Honorary Lecturer at the University of Exeter, with one foot in science and another in conservation. She's both a behavioral ecologist, focusing on whales and dolphins, and a leading voice—for more than a decade now—urging conservationists to take animal cultures seriously. Here, Philippa and I talk about how researchers define culture and social learning in animals. We tour the mounting evidence for culture across species—in birds, in apes, in fish, possibly even in insects. We discuss the methods that scientists use to infer that behaviors are socially learned. We consider how animal culture complicates the conservation enterprise. We also discuss the idea that animal cultures have intrinsic value—not value for us humans, not value that can be easily quantified, but value for the animals themselves. Along the way Philippa and I talk about the notion of "cultural rescue"; indigenous understandings of animal culture; cases where social learning is maladaptive; human-animal mutualism; fashion trends; the idea of conserving "cultural capacity"; elephant matriarchs and other "keystone individuals"; golden lion tamarins, herring, and regent honey-eaters; and the question of why some orcas where salmon as hats. Alright friends, this topic has been on our wish list for a while now. Hope you enjoy it!

  • 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. If you're enjoying Many Minds, you might consider leaving us a rating or review on your platform of choice, or maybe giving us a shout-out on social media. Thanks so much in advance for supporting us friends! Notes 4:30 – For a broad orientation to memory research in the cognitive sciences, see here. For a broad orientation to the philosophy of memory, see here. 13:00 – See here for Dr. Boyle's paper on the "impure phenomenology" of episodic memory. 16:30 – For more on the idea of "WEIRD"-ness and the "WEIRD problem" in psychology, see our previous audio essay and our recent episode on childhood across cultures. 20:00 – For more on metaphors for memory in the cognitive sciences, see here (in which an apparently different "cow stomach" metaphor for memory is discussed). Note that cows do not, in fact, have four stomachs, but rather a single stomach with four distinct chambers. 24:00 – For an overview of the cognitive neuroscience of episodic memory, see here. 31:30 – For a discussion of the commonsense "mnemonic view" of episodic memory, see Dr. Boyle's recent article. 37:00 – For one influential articulation of a "simulationist" account of episodic memory, see here. 40:00 – For the proposal by Dr. Mahr and his colleague that episodic memory is for communication, see here and here. 45:00 – For more on evidential systems in language, see here and here. 48:00 – For the study by Dr. Mahr and colleagues on source memory in children, see here. 51:30 ­– For Dr. Boyle's proposal that episodic memory is for semantic memory, see here. For another of Dr. Boyle's discussions of the functions of episodic memory, see here. 1:02:00 – For more of Dr. Mahr's ideas about the cultural evolution of the "epistemic tag" that distinguishes episodic memory, see here. 1:03:00 – Partially digested stomach contents are sometimes known as "chyme." 1:07:00 – A news story about recent findings on infantile amnesia. 1:08:00 – A recent review article about Highly Superior Autobiographical Memory. 1:12:00 – An empirical study on the phenomenology of "cryptomnesia." 1:15:00 – For a recent discussion of episodic memory in animals, see this paper by Dr. Boyle and a colleague.
