David Stove once observed, “As an item on the intellectual agenda, Marxism is scarcely even a joke… . Marxism is a fearful social—and police—problem, but so is the drug trade. It is a fearsome political problem, but so is Islamic fundamentalism. But an intellectual problem Marxism is not, any more than the drug trade or Islamic fundamentalism.”
