‘[A]ll ideology hails or interpellates concrete individuals as concrete subjects … I have called interpellation or hailing, and which can be imagined along the lines of the most commonplace everyday police (or other) hailing: ‘Hey, you there!’ … But in reality these things happen without any succession. The existence of ideology and the hailing or interpellation of individuals as subjects are one and the same thing … what thus seems to take place outside ideology (to be precise, in the street), in reality takes place in ideology. What really takes place in ideology seems therefore to take place outside it. That is why those who are in ideology believe themselves by definition outside ideology … It is necessary to be outside ideology, i.e. in scientific knowledge, to be able to say: I am in ideology … or … I was in ideology. As is well known, the accusation of being in ideology only applies to others, never to oneself.’
