Stuart Hall, sociology professor at Britains Open University, discusses why race matters so much to so many people, uncovering the cultural basis for racism and arguing that each society defines racial difference in its own terms, so that any battl e against racism must be understood in a discursive context. The reference edition, a video transcript of his presentation at Goldsmiths College, London, includes a 20 minute question and answer session following the lecture. Produced and directed by Sut Jhally.
