Ideological state apparatuses (
ISA), according to Althusser, use methods other than physical violence to achieve the same objectives as RSA. They may include educational institutions (e.g. schools), media outlets, churches, social and sports clubs and the family. These formations are ostensibly apolitical and part of
civil society, rather than a
formal part of the state (i.e. as is the case in an RSA). In terms of psychology they could be described as
psychosocial, because they aim to inculcate ways of seeing and evaluating things, events and class relations. Instead of expressing and imposing order, through violent repression, ISA disseminate ideologies that reinforce the control of a
dominant class. People tend to be co-opted by fear of
social rejection, e.g. ostracisation, ridicule and isolation. In Althusser's view, a social class cannot hold state power unless, and until, it simultaneously exercises
hegemony (domination) over and through ISA. Educational ISA, in particular, assume a dominant role in a capitalist economy, and conceal and mask the ideology of the ruling class behind the "liberating qualities" of education, so that the hidden agendas of the ruling class are inconspicuous to most teachers, students, parents and other interested members of society. Althusser said that the school has supplanted the church as the crucial ISA for
indoctrination, which augments the reproduction of the relations of production (i.e. the capitalist relations of exploitation) by training the students to become sources of
labour power, who work for and under capitalists. However, because ISA cannot dominate as obviously or readily as RSA, ideological state apparatuses may themselves become a site of
class struggle. That is, subordinate social classes are able to find the means and occasions to express class struggle politically and in so doing counter the dominant class, either by utilizing ideological contradictions inherent in ISA, or by campaigns to take control of positions within the ISA. This, nevertheless, will not in itself prevent the dominant class from retaining its position in control of RSA. ==Two theses on ideology==
