This debate is required viewing for anyone who appreciates the work of either of these two great minds. It takes place in 1971 as the war in Vietnam rages on. They discuss their respective specialties, human nature, the direction of society, society’s institutions, class warfare, capitalism, Marxism, anarcho-syndicalism, and much more.
This article from Roar Magazine (which claims a share of the credit for translation) about the debate adds some interesting background information and contains a full transcript of the discussion.
There is also another complete version that doesn’t appear to omit anything except the additional commentary; though most would probably benefit from the clarifications of the commentator included in the first video.
