Steven C. Hayes is a prominent American clinical psychologist and researcher known for his foundational work in behavioral science and psychotherapy with a focus on human language, cognition, and alleviating suffering. He developed Relational Frame Theory (RFT), which explains human higher cognition, and originated Acceptance and Commitment Therapy (ACT), an evidence-based psychotherapy. We explore why our evolution as social primates has left us with a mind that we can’t forget. Dr. Hayes explains how to transition from a life of emotional struggle to one of true psychological flexibility. We also explore the relationship of pursuing happiness and how this may ultimately lead to the opposite, the differences between being in pain and suffering, the concept of experiential avoidance, the concept of cognitive attachment, the evolutionary development of language and human cognition, and the science of developing psychological flexibility.

The idea that love is a feeling rather than an appetite for something may be part of the marketing surrounding Valentine's Day; in other words, love is viewed as satisfaction, completion, or a secure sense of emotions. However, Plato has an entirely different view. In this episode, I take a look at Plato's "Symposium," which is arguably one of the most upsetting, and authentic descriptions of love ever put on paper. It is through Socrates' and Diotima's explanations that Plato describes love as absence, longing, and as a movement toward something we don't yet possess.

John Vervaeke is a cognitive scientist and philosopher best known for his work on the modern meaning crisis, wisdom, and the nature of human understanding. He is a professor at the University of Toronto and the creator of Awakening from the Meaning Crisis, a widely influential lecture series exploring why modern life feels increasingly disconnected, fragmented, and nihilistic. In this episode, we explore what happens to love, truth, and meaning in a nihilistic world. We discuss Socrates and Plato on eros and the examined life, the role of love in orienting us toward reality, and why truth cannot be reduced to method or calculation alone. We examine the consequences of modernity, Nietzsche’s warning about nihilism, the loss of wisdom as a way of life, and why rationality without care leads to a crisis of meaning. We also consider whether love is a condition for truth rather than its rival, and how recovering wisdom may be essential for confronting the challenges of modern life.

John Cottingham is one of the world’s leading scholars of René Descartes and early modern philosophy. He is Professor Emeritus of Philosophy at the University of Reading and the author of several influential books on Descartes, ethics, and philosophy of religion. Cottingham is also widely known for his work on the Cambridge Edition of the Works of Descartes, where he served as editor and translator, helping shape how Descartes is read and understood today. In this episode, we explore Descartes’ philosophy from its foundations to its modern consequences. We discuss the method of radical doubt, the meaning of “I think, therefore I am,” the mind–body problem, and why consciousness still resists purely scientific explanation. We also examine the central role God plays in Descartes’ system, whether reason alone can justify belief, and how these ideas continue to shape debates in philosophy, science, and artificial intelligence today.

Nothing can be trusted to be real, or at least, that’s the starting point. In this episode, I break down René Descartes’ method of radical doubt by walking through the First and Second Meditations, step by step. What happens if you treat everything that can be doubted as false? That includes; your senses, your body, the external world, and even mathematics.

As we enter 2026, I wanted to take a step back and reflect on some of the books I read this year, and what they made me rethink about life, meaning, power, consciousness, and society. Check out the chapter names to see books discussed in this video. Let me know in the comments what you’re planning to read in 2026, and whether you have read any of these before.

Was education ever meant to make you employable or fix your career? In the final book of Politics, Aristotle argues that this assumption misunderstands education from the beginning. According to Aristotle, education primarily exists for the sake of leisure, here understood as freedom from necessity and the condition for contemplation. This understanding proposes that a life organized entirely around usefulness and efficiency may function, but it cannot flourish. In this episode, I unpack Aristotle’s most demanding claims about education, virtue, habituation, music, physical training, and the role of the city in shaping character. Aristotle draws sharp distinctions between usefulness and nobility, cleverness and virtue, play and leisure, work and the activities that are worth pursuing for their own sake. There might be some FPS drops in the beginning of the video, which gets better later. This was due to unidentified technical issue during the recording. I apologize for this. However, the audio and the pacing is consistent throughout the episode, so it should not diminish the quality of experience.

Did Aristotle sketch the foundations of something like Universal Basic Income in ancient times? In Book VII of Politics, he argues that no citizen should live in a state of constant labor and necessity, because leisure is the precondition for virtue, philosophy, and judgment. In this episode, I walk through his surprising claims about basic sustenance, land distribution, civic roles, military power, and why a well-designed city must give its citizens the freedom to think, reflect, and flourish. Aristotle connects everything: virtue, happiness, citizenship, leisure, even city walls and cold plunges into one vision of how a society creates excellent human beings. Source for this discussion: Aristotle, Politics, Book VII (Chapters 9–14).

Aristotle never treated philosophy as a luxury or something that you do when you are bored. In Book Seven of Politics, he forces a difficult question: can the philosophical life become a retreat from real action? And if so, what does that say about the lives we choose? What is worth pursuing at the end of the day? And what is ultimately meaning of life? In this episode, I break down Aristotle’s argument that happiness is found in living life according to virtue, and both philosophical / scientific life and active civic life are virtuous. Virtue comes from action and from the choices you make, the habits you build, and the character you sharpen. Thought without action becomes passivity. Action without thought becomes chaos. The good life lies in the tension between them. Aristotle also explores the oldest divide in human life: the active citizen versus the pure thinker.
