We discuss Buddhis...

In this episode, Professor Jon Abramowitz and I explore OCD, intrusive thoughts, compulsions, anxiety, uncertainty, reassurance, and exposure and response prevention. We discuss what OCD is, why it is much more than being tidy or washing your hands, and how intrusive thoughts can become distressing obsessions when they are treated as dangerous, meaningful, or morally important. Professor Abramowitz also explains why OCD often attaches itself to the areas of life people value most. We also discus...

In this episode, Mr. Tim LeBon and I explore Stoicism, CBT, philosophical counselling, Stoic Week, and how ancient philosophy can be used practically in modern life. We discuss his work as a psychotherapist and CBT therapist, his involvement in Modern Stoicism, and the origins of Stoic Week as an experiment in trying Stoic exercises for everyday life. Mr. LeBon explains Stoicism as a philosophy of living well through virtue, wisdom, courage, self-control, justice, Stoic mindfulness, and learning...

In this episode, Professor Harry Reis and I explore love, relationships, intimacy, listening, vulnerability, attachment, loneliness, and his new book How to Feel Loved. We discuss the difference between being loved and feeling loved, why relationships are central to happiness and meaning, and why trying to “make” someone love you is usually the wrong approach. Instead, we explore how curiosity, listening, compassion, and warm conversation can create a stronger sense of connection between people....

In this episode, Professor William B. Irvine and I explore thinking, open-mindedness, Stoicism, audience capture, echo chambers, and how to become more reasonable in unreasonable times. We discuss his journey into philosophy, his work on thinking more and better, and how online platforms can tempt creators to chase numbers rather than produce genuinely valuable work. We also discuss how to choose better information sources, avoid intellectual blind spots, listen to critics, and recognise contrad...

In this episode, Professor Karl Friston and I explore brain imaging, dynamic causal modelling, statistical parametric mapping, computational psychiatry, and selfhood through active inference. We discuss how functional brain imaging works, how it helps reveal specialised brain regions, and how researchers study the connectivity and causal interactions between different parts of the brain.

In this episode, Professor Michael Levin and I explore bioelectricity, collective intelligence, regeneration, aging, cancer, and the future of medicine. We discuss how cells communicate through electrical signals, how groups of cells coordinate to build bodies, limbs, organs, and faces, and how biology can be understood through goals, memory, problem-solving, and intelligence, not only chemistry. We also discuss how bioelectric patterns may guide development, repair, and regeneration, why humans...

In this episode, Professor Nancy McWilliams and I explore psychoanalysis, personality, defenses, trauma, shame, narcissism, and the therapeutic relationship. We discuss what psychoanalysis is, why unconscious feelings and thoughts matter, and how personality styles develop from early adaptations to a person’s childhood environment.

In this episode, Professor Stuart Firestein and I explore ignorance, failure, uncertainty, and how science really progresses. We discuss why science is driven by questions as much as facts, why education often rewards answers over curiosity, and how better questions can lead to deeper understanding. We also discuss why failure is not the opposite of success, but an essential part of discovery. Finally, we explore It Could Be Otherwise, uncertainty, optimism, progress, medicine, biology, and how ...

In this episode, Professor David Veale and I explore OCD, intrusive thoughts, compulsions, avoidance, reassurance seeking, and how OCD is treated. We discuss what OCD is, why intrusive thoughts become powerful, how obsessions often attach to the things people value most, and why OCD is not simply being tidy, clean, or perfectionistic. Professor Veale explains different forms of OCD, including contamination fears, responsibility for harm, unacceptable sexual or violent thoughts, religious fears, ...

In this episode, Lord Martin Rees and I explore cosmology, the Big Bang, exoplanets, alien life, multiverses, and humanity’s long-term future. We discuss how our understanding of the universe expanded from Earth-centred views to galaxies, the Big Bang, and the possibility of many other worlds where life may exist. Lord Rees also explains why humans may still be near the beginning of our story, if we can avoid destroying ourselves this century. We then turn to existential risks, including nuclear...

In this episode, Professor Nancy Sherman and I explore Stoicism, emotions, virtue, military ethics, moral injury, and what it means to live well. We discuss common misconceptions about Stoicism, especially the idea that being Stoic means suppressing emotion, and explore how Stoicism instead aims to train our emotions, judgments, and responses. We also discuss anger, proto-emotions, joy, distress, practical wisdom, courage, generosity, friendship, and how ancient philosophy can guide everyday lif...

In this episode, Gregory Lopez and I explore Stoicism as a practical philosophy of life. We discuss what Stoicism is, what the Stoics meant by virtue, excellence, and living according to nature, and why human beings are understood as rational and pro-social animals. Gregory explains Stoic psychology, including reason, emotion, impressions, assent, passions, value judgments, and why Stoicism is not about suppressing emotions or becoming unfeeling. We also discuss why “control” can be a misleading...

In this episode, my grappling coach Yousuf Nabi and I discuss Brazilian Jiu-Jitsu, coaching, competition, mental health, and building community. Yousuf shares how he started training BJJ after first discovering the Gracie family through early MMA footage, and how that eventually led him to open Elements in Brighton as a way to create more training opportunities locally. We talk about how the gym evolved from a passion project into a proper business and community, why Jiu-Jitsu can build confiden...

In this episode, Professor Graham Priest and I explore logic, paradoxes, metaphysics, and Buddhist philosophy. We discuss what logic is, what makes an argument valid, and how philosophers think about premises, conclusions, reasoning, and theories of logic. Professor Priest explains classical logic, non-classical logic, paraconsistent logic, contradictions, explosion, and why some philosophers think certain contradictions may be true. We also explore the liar paradox, Russell’s paradox, realism, ...

In this episode, Professor Ian Hodder and I explore Çatalhöyük, one of the world’s most important archaeological sites. We discuss what archaeology is, how excavation works, and why Çatalhöyük gives us such a rare insight into the beliefs, myths, art, and daily life of people living around 9,000 years ago. Professor Hodder explains the role of ancestors, vultures, wild animals, domesticating plants and animals, and the transition from hunter-gatherer life to settled farming communities. We also ...

In this episode, Professor Ruth Kinna and I explore anarchism, mutual aid, self-government, and anti-authoritarian political thought. We discuss what anarchism means, its history and major thinkers, including Proudhon, Bakunin and Kropotkin.

Finally, Professor Kinna explains mutual aid, anarchist approaches to...

In this episode, Professor David Geary and I discuss sex differences, mathematical cognition, and the evolution of the human mind. We explore why maths, reading, and writing are evolutionarily recent skills, how they build on older systems like language and number sense, and why children may struggle with maths or reading. We also discuss male and female cognitive similarities and differences, including language, visual-spatial reasoning, mechanical reasoning, and how these may affect education....

In this episode, Professor Geoffrey West and I explore complexity, scaling laws, cities, biology, and the future of humanity. We discuss what makes a system “complex” rather than simple and why physics can describe so much of the universe through elegant equations, yet still struggles to capture the messy world of organisms, cities, companies, politics, poetry, conflict, and human society. We also examine scaling laws in biology and cities: why larger animals use energy differently, why heart ra...

In this episode, Dr. Sophie Scott-Brown and I explore anarchism, democracy, political power, and the history of radical political thought. We discuss what anarchism is, why it is difficult to define, and why anarchist thought is often more pluralistic than people assume. Dr. Scott-Brown explains how anarchism challenges permanent structures of authority and how people already organise parts of everyday life through informal cooperation. We also examine representative democracy, direct democracy,...

In this episode, Dr. Carl Safina and I explore animal minds, sentience, consciousness, and humanity’s relationship with the natural world. We discuss how other animals experience the world, what makes humans similar to and different from other species, and whether animals such as insects, worms, birds, mammals, dolphins, and octopuses may be conscious or sentient. Dr. Safina explains animal culture, learning, awareness, emotion, and the difficulty of knowing where consciousness begins in the liv...

In this episode, Professor Graham Oppy and I explore arguments for and against the existence of God. We discuss cosmological, design, moral, ontological, and other arguments, as well as naturalism, atheism, agnosticism, and how worldviews are formed. Professor Oppy explains what makes a philosophical argument strong, why disagreements about God are so difficult to resolve, and why he thinks there are no successful arguments on either side that force everyone to agree. We also explore the problem...

In this episode, Mr Alfie Kohn and I explore why rewards can backfire just as punishment can. We discuss intrinsic and extrinsic motivation, why grades, praise, bonuses, and incentive systems can undermine genuine interest, and why rewards and punishments are ultimately two forms of control. Mr Alfie explains how parents can move away from conditional acceptance and towards working with children to solve problems, while helping them feel loved regardless of their achievements. We also explore ho...

In this episode, Professor Sugata Mitra and I explore how education could change in a world shaped by the internet and artificial intelligence. We discuss his famous Hole in the Wall experiment, self-organised learning environments, and why groups of children can often teach themselves when they have access to technology, questions, and one another. Professor Mitra explains why the teacher’s role should shift from delivering answers to guiding students through questions and discovery. We also ex...
