The third Tedcast takes a break from my Fantasy & Science Fiction lectures to present an interview with me conducted by Erik Davis. Erik hosts Expanding Minds on the Progressive Radio Network, and is author of numerous books, including a great study of Led Zeppelin IV and the new collection Nomad Codes. Erik and I go back to college, where we worked together on a zine. Here we talk about the Centaur Manifesto, critical theory, and the tensions between being an academic and a public intellectual.
