I’m underground as I write this, one day before taping the conversation you’re about to hear, speeding through New York City subway tunnels that aren’t all that ancient but whose darkness, and rats, and crumbling, esoteric infrastructure holds fear and fascination enough for anyone who contemplates them. Waking up this morning—notice how you wake up, not down—I felt my already barely remembered dreams sliding off of me in layers, like leaves, or hands. And the longing to submit to those hands and slide back down, underground, into the caverns of sleep.
My guest today, Robert MacFarlane), has dug deeper than I could ever hope to into the meanings and magnetism of the underworld —tunnels, caves, sinkholes, and the living, fungal earth of our world and our imaginations. At one point in his new book UNDERLAND) he brings up the fact that to a neutrino, our solid physical world is just a a mesh—Mount Everest is a wide-gauge net it can pass easily through. In MacFarlane’s writing, the layers of the world are transparent, overlapping, always already present. He’s often called a “nature writer”, but that’s a poor proxy for what he actually is: a philosopher poet with the gift of sight in the darkness, whose penetrating vision turns the world inside out.
