While speaking in ideology, and from within ideology we have to outline a discourse which tries to break with ideology, in order to dare to be the be… - Louis Althusser

For you and for me, the category of the subject is a primary ‘obviousness’ (obviousnesses are always primary): it is clear that you and I are subjects (free, ethical, etc.). Like all obviousnesses, including those that make a word ‘name a thing’ or ‘have a meaning’ (therefore including the obviousness of the ‘transparency’ of language), the ‘obviousness’ that you and I are subjects – and that that does not cause any problems – is an ideological effect, the elementary ideological effect. It is indeed a peculiarity of ideology that it imposes (without appearing to do so, since these are ‘obviousnesses’) obviousnesses as obviousnesses.

I shall call Ideological State Apparatuses (ISAs) a certain number of realities which present themselves to the immediate observer in the form of distinct and specialized institutions: ...

But someone is bound to question ... by what right I regard as Ideological State Apparatuses, institutions which for the most part do not possess public status, but are quite simply private institutions. As a conscious Marxist, Gramsci already forestalled this objection in one sentence. The distinction between the public and the private is a distinction internal to bourgeois law, and valid in the (subordinate) domains in which bourgeois law exercises its ‘authority’. The domain of the State escapes it because the latter is ‘above the law’: the State, which is the State of the ruling class, is neither public nor private; on the contrary, it is the precondition for any distinction between public and private. The same thing can be said from the starting-point of our State Ideological Apparatuses. It is unimportant whether the institutions in which they are realized are ‘public’ or ‘private’. What matters is how they function.
