US Idealism Pragmatism vs. French post-modern meme archiology

Still one of the best YouTube videos i have ever found, this Noam Chomsky | Michel Foucault debate from 1971 is an intellectual delicatess (and the awesome hippie atmosphere adds even visual appeal).

Sidenote: Isn't it cool how these two über-intellectuals claim to talk to each other, while speaking on completely different subjects ;-) Chomsky first elaborates on conditions/components for an ideal social order - then Foucault counters by saying he doesnt even understand the current system and speaks about power - to what Chomsky replies he needs the ideal to inform his actions. Or might there be a connection after all??
