Could a single theory explain the fundamental workings of the universe? Theoretical physicist Michio Kaku joins Robert Lawrence Kuhn to discuss The God Equation and the quest for a Theory of Everything. They explore string theory, the multiverse, higher dimensions, time travel, the Big Bang, and what a final theory might reveal about reality and our place in the cosmos. This conversation was…
Can your theory of consciousness determine your answers to the biggest questions in philosophy, science, and religion — AI sentience, life after death, free will, personal identity? Robert Lawrence Kuhn presents his landmark taxonomy of consciousness theories — spanning materialism, quantum theories, information, panpsychism, dualism, idealism, and more — and argues that every serious question…
Everything we know, everything we think, comes from our brain. Are brains our window to reality, seeing what truly exists? Or are we bound by brains, mental slaves of the meat in our heads?

What is “nothing”? What does it mean for nothing to exist—or for nothing to have ever existed? In this episode, Robert Lawrence Kuhn explores one of philosophy’s deepest questions: Why is there something rather than nothing? Through conversations with philosophers and physicists, the discussion examines the nature of nothingness, whether absolute nothing is possible, and how different…
How do natural laws shape human societies? In this conversation, Saleem Ali discusses Earthly Order: How Natural Laws Define Human Life , exploring connections between natural systems, social organization, economics, and political order. Ali examines how concepts such as order, chaos, emergence, hierarchy, and complexity operate across scales—from physics and ecology to governance and global…

Drawing from his book Galileo: And the Science Deniers , Livio explores Galileo’s role in the development of the scientific method and examines how…
Do we really have free will? In this conversation, Gregg Caruso explores the philosophy of free will, moral responsibility, determinism, compatibilism, libertarian free will, and free will skepticism. Discussing themes from Just Deserts: Debating Free Will , co-authored with Daniel Dennett, Caruso examines whether human beings possess the kind of control required for moral responsibility and how…
How do we measure the expansion of the universe? In this conversation, Wendy Freedman discusses the Hubble constant, standard candles, redshift, and the ongoing effort to determine the age, size, and evolution of the universe. Exploring Cepheid variables, supernovae, cosmic expansion, and the tension between competing cosmological measurements, Freedman explains how increasingly precise…
What does evolution imply about human nature and human value? In this conversation, Michael Ruse explores the philosophy of biology, the mechanistic view of life, human exceptionalism, and the relationship between evolution and meaning.
