Not as famous as Derrida, perhaps farther from the truth of things. And yet, somehow, so much more useful. (Marxists always are). Marxists can be thinkers inasmuch as they begin to realize that the banal vision of communism is just as much a nightmare as capitalism. Anyway, this obituary is really quite good, anyone interested in paying tribute to one of the centuries greatest philosophers would do well to read it.
