Anarchism, Socialism, Marxism

Proudhon's Anarchism is a variety of Socialism that diverges from Marxism in two respects.  First, it entails no Dialecticism, and, second, it rejects the centralization of Marxism.  Now, the failure of Marxists to establish an essential connection between Socialism and Dialectics leaves Proudhon's variety of the former deficient in no obvious respect with the absence of the latter.  However, the other divergence is not as clear-cut as it sometimes seems to be taken.  For, his Federalism entails at least some unity of the multiplicity of citizens, so its distinction from Marxist centralization is only one of degree, not kind.
