In this episode, Sam and Jordan follow their tradition of discussing some random nonsense and then digging into a deep philosophical topic. This week it's possible worlds. Some philosophers, like some physicists, believe in a multiverse of "parallel universes" or "possible worlds." But philosopher David Lewis didn't need any fancy telescopes to develop his theory; all he had to do was sit in a comfortable armchair, stroke his beard, and ask questions like, "Am I Batman in another possible world?" Well, maybe he didn't ask that question. But WE do!
