A 1971 debate between Noam Chomsky and Michel Foucault on the origins of human nature, and the relative merits of innatist theories and learned paradigms. Somewhat heavy on philosophical jargon, this is nonetheless an intensely interesting conversation between two highly intelligent and thoughtful thinkers.
One in a series of lectures in the International Philosopher's Project, this debate was originally entitled 'Human Nautre: Justice vs. Power'. This clip is from Dutch television, hence the Dutch subtitles, although the video itself is in English and French.
