Jennifer Wang (Stanford University) introduces us to a puzzle that has bedeviled philosophy since the ancient Greeks: the Ship of Theseus. She tells the Ship of Theseus story, and draws out the more general question behind it: what does it take for an object to persist over time? She then breaks this ancient problem down with modern clarity and rigor. Help us caption & translate this video! http://amara.org/v/Ep6h/
