Philosopher Meghan Sullivan and space architect Ariel Ekblaw don't usually work at the same altitude ... but put them in a room together, and they'll answer the big questions. Drawing on wisdom from Aristotle to astronauts, they discuss what humans inherently owe each other, what it takes to live a good life and what a rulebook for a better world might look like. (This conversation is part of “TED Intersections,” a series featuring thought-provoking conversations between experts navigating the ideas shaping our world.) Hosted on Acast.
