This one’s going to rock your world. In episode 132 of Overthink, Ellie and David dig into the earth for the third part of their four-part series on the elements. They discuss everything from earthworms and carbon dating to the “solidity” of the earth. They look to Foucault, Freud, and Husserl for insights about how the earth can act as a metaphor for the mind and for the past. They also wonder: Is the earth inert matter or a living being? And why do so many creation myths present humans as “made” of earth/clay/mud? So, what is it that we actually mean when we talk about earth as an element? In the bonus, your hosts talk think through Heidegger’s notion of ground and horizon, and the Western association of land with earth.
