Marx was not a scientist, as he claimed. He founded a faith. The economic and political systems he inspired are dead or dying. But his religion is a broad church, and lives on.actually, the strains of chiliasm run deep in marx, and the source is, as david horowitz notes, in judiasm.
I looked up chiliasm, and found it to be a belief that Jesus Christ will reign on Earth for a 1000 year period. Why would Jews perpetuate that?
