The explanation Marxism offered of the significance of History was ludicrously simple, and in this very simplicity lay its charm, and its strength. The whole history of the world was merely the record of the struggle of classes. Religion, philosophy, science, technics, music, painting, poetry, nobility, priesthood, Emperor and Pope State, war, and politics - all are simply reflections of economics. Not economics generally, but the "struggle" of "classes." The most amazing thing about this ideological picture is that it was ever put forward seriously, or taken seriously.
