Season 5 of Hi-Phi Nation will begin with a mini-series on the life and works of David Kellogg Lewis, one of the greats of the latter half of the 20th century who died 20 years ago, and who would have been 80 years old today. After a very heavy fourth season and a very heavy two years for the world, we are going to cover much lighter topics, from David Lewis on time travel, alternate universes, and conversational scorekeeping, to the roles vampires, zombies, cannibals, and demons play in philosophy. We’ll also have an episode on altruism and on de-extinction. Please tell all your friends to subscribe so you don’t miss the season. Here is a picture of David Lewis in his 20s from his college yearbook, and a clip of him speaking to Australians in 1981.
