Marxism

"This is because Marxism looks at things as a whole and in relation to each other—or tries to, but its limitations are not the point for the moment. A person who has been influenced by Marxism takes it for granted that an event in Siberia will affect one in Botswana. I think it is possible that Marxism was the first attempt, for our time [written in 1971], outside the formal religions, at a world-mind, a world ethic. It went wrong, could not prevent itself from dividing and subdividing, like all the other religions, into smaller and smaller chapels, sects and creeds. But it was an attempt."
