How does something living emerge from something that isn't? In this episode, Lee Cronin pushes the question back even further: before cells, before DNA, before biology as we usually think of it, what kind of process could make matter start organizing itself into something alive? He and Michael Shermer get into assembly theory, RNA, autocatalysis, and the deeper puzzle of whether causation and selection may already be at work long before the first organism appears. The conversation also branches into consciousness, free will, and the possibility that life may be widespread in the universe, even if it looks nothing like life on Earth. Lee Cronin is Regius Professor of Chemistry at the University of Glasgow, Scotland, where he leads one of the world's largest multidisciplinary chemistry research groups. He has raised more than $35 million in grant funding, with current research income of $15 million, and has authored more than 350 peer-reviewed papers, including recent work published in Nature, Science, and PNAS. He and his team are trying to make artificial life forms, find alien life, explore the digitization of chemistry, understand how information can be encoded into chemicals and construct chemical computers.

Why does being alive feel like something? Neuroscientist Antonio Damasio argues that the answer begins with the body's need to stay alive. Hunger, thirst, pain, and pleasure tell us how we're doing and push us to act. These basic feelings, he says, are the foundation of consciousness. Damasio returns to the show to discuss his new book, Natural Intelligence and the Logic of Consciousness, why feelings and emotions are different, what your dog knows about you, and why he thinks Francis Crick looked in the wrong place for the origins of conscious experience. If consciousness depends on a living body, could a computer ever have it? And would uploading your brain actually preserve you? Damasio leaves room for a form of machine consciousness, though he argues it would be fundamentally different from ours. He also talks about what brain injuries reveal about the mind, how psychedelics change our perception, where human choice comes from, and why religion offers such powerful comfort. Antonio Damasio is David Dornsife Professor of Neuroscience, Psychology and Philosophy, and director of the Brain and Creativity Institute at the University of Southern California, Los Angeles. Considered one of the most eminent scientists of our time, he has made fundamental contributions to the understanding of brain processes and their relationship to emotions and consciousness. He has discussed his research in books such as Descartes' Error, The Sensation of What Happens, Looking for Spinoza, and The Strange Order of Things.
Can fighting racism end up reinforcing it? Shelby Steele grew up under segregation and became a Black militant in the 1960s.
What do you make of an experience you can't explain? A strange light in the sky, a book flying off a desk, a coincidence that feels too improbable to be chance? Social psychologist Barry Markovsky joins Michael Shermer to discuss his new book Everyday Extraordinary and the experiences that have kept him studying paranormal beliefs for decades—including his own childhood UFO sighting and a supposedly haunted vape shop. Markovsky explains how friends, communities, and our sense of who we are shape what we believe—and why changing someone's mind can take more than better evidence. Barry Markovsky is Distinguished Professor Emeritus of Sociology at University of South Carolina. His articles on ghosts, UFOs, and coincidences appear at TheConversation.com, which disseminates them to major news outlets worldwide. To date, more than a million readers have downloaded them. His new book is Everyday Extraordinary.
If we could explain everything happening in your brain, would there still be something left to explain about you? Physicist Avshalom Elitzur thinks so—and argues that accounting for consciousness may require changing the laws of physics. In this lively conversation, Michael Shermer challenges Elitzur on why subjective experience should be anything more than a product of the brain, whether an AI could be conscious, and what a hypothetical human without consciousness would have to say about any of this. Avshalom Elitzur is an Affiliate Professor at the Institute for Quantum Studies, Chapman University, and a senior researcher at Iyar, the Israel Institute for Advanced Research. He works in the foundations of quantum mechanics and is best known for the Elitzur–Vaidman bomb-testing problem.
Would World War II have happened without Hitler? Would someone else have built Apple without Steve Jobs? Jared Diamond joins Michael Shermer to ask how much history depends on particular people. From Darwin's discoveries to the rise of Christianity, Diamond considers when someone is truly irreplaceable, when someone else would have done much the same thing, and how we can tell the difference. Jared Diamond is the Pulitzer Prize-winning author of the seminal million-copy-bestseller Guns, Germs, and Steel, which was named one of Time magazine's best non-fiction books of all time, Collapse, a No. 1 international bestseller, and The World Until Yesterday, among other books. A professor of geography at UCLA and noted polymath, Diamond's work has been influential in the fields of anthropology, biology, ornithology, ecology and history, among others. His new book is Profits, Prophets, Coaches, and Kings: (When) Do Leaders Matter?
