When I wasn't paying attention Jeff Riggenbach did two more audio podcasts on libertarianism and science fiction in his series for the Mises Institute, The Libertarian Tradition. Here is one, a followup on the previous podcast on libertarian science fiction.
You can also read the transcript, which was later published as a Mises Daily article: “Some Further Notes on Libertarian Science Fiction.”
In the podcast, Riggenbach discusses Anthony Burgess's novel A Clockwork Orange and several novels by Philip K. Dick (including The Man in the High Castle, which our own Matthew Alexander recently reviewed) as well as two nonfiction books.
