Marxian Utopia?: A Theoretical Critique of Marxism

In the first stage of his thinking Karl Marx founded his revolutionary politics on philosophical speculation, while in the second (mature) stage he relied on economics and the theory of exploitation based on his theory of surplus value. Marxism, however, developed in the opposite direction. After Marx's economic doctrine became vulnerable to powerful objections, Marxists tried to find a refuge in his early philosophical writings and in this way avoid refutation. Ultimately this attempt proved unsuccessful too.
