while functioning secondarily by ideology. (There is no such thing as a purely repressive apparatus.) For example, the Army and the Police also function by ideology both to ensure their own cohesion and reproduction, and in the 'values' they propound externally.

In the same way, but inversely, it is essential to say that for their part the Ideological State Apparatuses function massively and predominantly by ideology, but they also function secondarily by repression, even if ultimately, but only ultimately, this is very attenuated and concealed, even symbolic. (There is no such thing as a purely ideological apparatus.) Thus Schools and Churches use suitable methods of punishment, expulsion, selection, etc., to 'discipline' not only their shepherds, but also their flocks. The same is true of the Family. . . . The same is true of the cultural IS Apparatus (censorship, among other things), etc.

Is it necessary to add that this determination of the double 'functioning' (predominantly, secondarily) by repression and by ideology, according to whether it is a matter of the (Repressive) State Apparatus or the Ideological State Apparatuses, makes it clear that very subtle explicit or tacit combinations may be woven from the interplay of the (Repressive) State Apparatus and the Ideological State Apparatuses? Everyday life provides us with innumerable examples of this, but they must be studied in detail if we are to go further than this mere observation.

Nevertheless, this remark leads us towards an understanding of what constitutes the unity of the apparently disparate body of the ISAs. If the ISAs 'function' massively and predominantly by ideology, what unifies their diversity is precisely this functioning, in so far as the ideology by which they function is always in fact unified, despite its diversity and its contradictions, beneath the ruling ideology, which is the ideology of 'the ruling class'. Given the fact that the 'ruling class' in principle holds State power (openly or more often by means of alliances between classes or class fractions), and therefore has at its disposal the (Repressive) State Apparatus, we can accept the fact that this same ruling class is active in the Ideological State Apparatuses in so far as it is ultimately the ruling ideology which is realized in the Ideological State Apparatuses, precisely in its contradictions. Of course, it is a quite different thing to act by laws and decrees in the (Repressive) State Apparatus and to 'act' through the intermediary of the ruling ideology in the Ideological State Apparatuses. We must go into the details of this difference -- but it cannot mask the reality of a profound identity. To my knowledge, no class can hold State power over a long period without at the same time exercising its hegemony over and in the State Ideological Apparatuses. I need only one example and proof of this:
