This article seeks to identify the political and ideological dimensions of the contemporary presence of information technology or infotech. This presence is experienced as the progressive unfolding of technology as the logic of the social itself. Rather than approaching these dimensions through their reduction to a ground, a symbolic totality or a specific interest, and argument is constructed from Laclau and Mouffe's concept of `antagonism' in conjunction with Claude Lefort's notion of `invisible ideology'. This gives the argument the advantage of relating the constitution of ideology to a historically specific political formation, instead of positing a timeless relation to the constitution of an abstract subject as the ground of an explanation. The argument is that insofar as information technology appears as a substance that absorbs the dynamic of community, which I call autotechnopoiesis, then ideology constructs the identity of this space with itself. The political is understood as the failure of this self-presence. In conclusion, these issues are located in terms of the governmentality of the `performative state' which seeks the recruitment of subjects to the `promotion of the social' through an investment in the banality of communication.
