Karl Marx (1818-1883). The core of Marx's economic analysis found early expression in the Ökonomisch-philosophische Manuskripte aus dem Jahre 1844 (Economic and Political Manuscripts of 1844) (1844). There, Marx argued that the conditions of modern industrial societies invariably result in the estrangement (or alienation) of workers from their own labor. In his review of a Bruno Baier book, On the Jewish Question (1844), Marx decried the lingering influence of religion over politics and proposed a revolutionary re-structuring of European society. Much later, Marx undertook a systematic explanation of his economic theories in Das Kapital (Capital) (1867-95) and Theorien über den Mehrwert (Theory of Surplus Value) (1862).
