[Unedited] Robert Macfarlane with Krista Tippett
There\u2019s dark matter in the cosmos, and inside us, and hidden beneath our feet. Robert Macfarlane is an explorer and linguist of landscape and his book, Underland: A Deep Time Journey, is an odyssey that\u2019s full of surprises \u2014 from caves and catacombs under land, under cities, and under forests to the meltwater of Greenland. \u201cSince before we were Homo sapiens,\u201d he writes, \u201chumans have been seeking out spaces of darkness in which to find and make meaning.\u201d Darkness in the natural world and in human life, he suggests, is a medium of vision \u2014 and descent, a movement toward revelation.
