"Marxism was the deep structure of European radical thought. More than he realized, Marx himself synthesized many early nineteenth-century trends in social criticism and economic theory: he was, for example, both an exemplary French political pamphleteer and a minor commentator on classical British economics. And thus, this German student of Hegelian metaphysics bequeathed to the European Left the only version of its own heritage compatible with local traditions of radical anger and offering a story that could transcend them."
