Hi-Phi Nation

The Man of Many Worlds, Part 3

David Lewis argues for the existence of possible other worlds.


Episode Notes

In 1968, David Lewis decides that one truth can unify every theory he’s had about the nature of the universe. It is the truth that every possible world is equally real. Lewis not only argues for this view, but devises a distinctive way of arguing for it, a method of doing philosophy that is as influential as his views. Meanwhile, a soon-to-be colleague and rival, Saul Kripke, reads Lewis’ paper and fires off eight objections, and on the other side of the world, an entire continent becomes enamored with the life and works of David Kellogg Lewis, an admiration that survives to this day.

Guest voices include Frank Jackson, Alan Hajek, John Bigelow, Helen Beebe, Anthony Fischer, Peter Anstey, and David Lewis.

About the Show

Hi-Phi Nation is philosophy in story form, integrating narrative journalism with big ideas. We look at stories from everyday life, law, science, popular culture, and strange corners of human experiences that raise thought-provoking questions about things like justice, knowledge, the self, morality, and existence. We then seek answers with the help of academics and philosophers. The show is produced and hosted by Barry Lam of Vassar College.
