Marx compellingly proved it in Capital Volume Two, that no production is possible which does not allow for the reproduction of the material condition… - Louis Althusser

To be a Communist is to be a partisan and artisan of Marxism-Leninist philosophy: of dialectical materialism.'

Those who are in ideology believe themselves by definition outside ideology: one of the effects of ideology is the practical denegation of the ideological character of ideology by ideology: ideology never says, ‘I am ideological’. It is necessary to be outside ideology, i.e. in scientific knowledge, to be able to say: I am in ideology (a quite exceptional case) or (the general case): I was in ideology. As is well known, the accusation of being in ideology only applies to others, never to oneself (unless one is really a Spinozist or a Marxist, which, in this matter, is to be exactly the same thing). Which amounts to saying that ideology has no outside (for itself), but at the same time that it is nothing but outside (for science and reality).

Like every 'intellectual', a philosophy teacher is a petty bourgeois. When he opens his mouth, it is petty-bourgeois ideology that speaks: its resources and ruses are infinite.
