Evidence

The claim, presented as an essential postulate of historical materialism, that every fluctuation of politics and ideology can be presented and expounded as an immediate expression of the structure, must be contested in theory as primitive infantilism, and combated in practice with the authentic testimony of Marx, the author of concrete political and historical works. Particularly important from this point of view are The 18th Brumaire and the writings on the Eastern Question, but also other writings (Revolution and Counter-Revolution in Germany, The Civil War in France and lesser works). — Antonio Gramsci, Selections from the Prison Notebooks, 1447
