Philosophy 6, taught by Hubert Dreyfus. This is the first lecture (the sound has some glitches in the beginning but improves). The rest of the course is on Archive.org and includes lectures on The Odyssey, Oresteia, Aeneid, Gospel of John, The Divine Comedy, Pascal’s Pensees, and Moby Dick.
My 2008 online project, Isolatoes, was a direct result of listening in on this class.
