Ron Rosenbaum returns to the show to talk about the new edition of his amazing book, Explaining Hitler: The Search for the Origins of His Evil (Da Capo Press)! We talk Hitler, the meaning(s) of evil, determinism and free will, Hitler-as-artist vs. Hitler-as-suicide-bomber, "degenerate art," the tendency to blame Jews for their misfortune, and how internet culture has warped the meaning of Hitler in the 16 years since Ron's book was first published.
