The reproduction of the relations of production is secured by the legal-political and ideological superstructure. It is secured by the exercise of state power in the SA and the ISAs. The role of the repressive SA consists essentially in securing by force the political conditions of the reproduction of relations of production which are in the last resort relations of exploitation. The SA also secures by repression the political conditions for the action of the ISAs. The mechanisms which reproduce the exploitative relations of production are concealed by a universally reigning ideology of the school.
Ideology represents the imaginary relationship of individuals to their real conditions of existence.
Ideology has a material existence. The term ideas has disappeared. The terms subject, consciousness, belief, actions have survived. The terms practices, rituals, ideological apparatuses have appeared. There is no practice except by and in an ideology.
