Ep. 339: Brian Ellis on the Metaphysics of Science (Part Two)

The Partially Examined Life is a philosophy podcast by some guys who were at one point set on doing philosophy for a living but then thought better of it. Each episode, we pick a text and chat about it with some balance between insight and flippancy. You don't have to know any philosophy, or even to have read the text we're talking about to (mostly) follow and (hopefully) enjoy the discussion.
