Will Hunt (explorer) – into the Earth: the mysteries and meanings of underground spaces

The catacombs of Paris. Secret graffiti beneath NYC. The hidden cities of Cappadocia. Writer and explorer Will Hunt is your philosophical tour guide to what lies beneath.

  • "The surface of the earth is where we're rational . . . Part of us dreads the chaos, and part of us is always attracted to it."
  • "There were these things hanging from the ceiling…long strands of bacteria called "snotsicles"… But at our feet was a natural stream that had been running through Brooklyn forever."
  • "It's…about death. Undergoing a death. We're going into the other world and then retreating to the surface… changed in some way."


The first time I attempted to play Minecraft with my then-seven-year-old son, we immediately dug ourselves into a pit deep in the Earth and could not get out. In spite of the crappy 8-bit graphics, all of our primal, H.P. Lovecraftian terrors of the underground were activated. We were trapped! We were lost! We might die down here!

Will Hunt, on the other hand, has been climbing eagerly since childhood into dank and disorienting tunnels, caves, sewers, and other underground spaces, from abandoned New York City subway platforms to ancient Mayan temples of human sacrifice in the caverns of Belize. In his brilliant new book UNDERGROUND: a Human History of the Worlds Beneath Our Feet, he takes us physically and spiritually along on some of these adventures. Part global, subterranean travelogue, part meditation on human curiosity, UNDERGROUND plumbs the philosophical depths of our primal awe of what lies beneath. . . . and it almost makes me want to go play Minecraft, where at least there are no rats.

Land of paradoxes: the inner and outer Iran – with Delphine Minoui

Secret Spice Girls dance parties of the wives of anti-western morality police. Book deals for political prisoners still in jail. Iran is a land of contradictions where oppression and freedom uneasily coexist. Born in France, Delphine Minoui lived in Tehran for 10 years to understand her grandparents' country from the inside.

The philosophy of tragedy & the tragedy of philosophy - with Simon Critchley

Tragedy in art, from Ancient Greece to Breaking Bad, resists all our efforts to tie reality up in a neat bow, to draw some edifying lesson from it. Instead it confronts us with our own limitations, leaving us scrabbling in the rubble of certainty to figure out what's next.

  • Why democracy has been unpopular with philosophers
  • Tragedy's reminder that the past isn't finished with us
  • …and why we need art in the first place

Terry Gilliam - The impossible dream

The film becomes the story of the making of the film. From his Monty Python days to now, Don Quixote is a metaphor for Terry Gilliam's whole career, and for his 30 year project of making a film about a film about the knight of the woeful countenance. We talk about Muppets, time, and basically everything else two humans can talk about.
