Louis Althusser: ISA’s & the notion of ‘Interpellation’

all ideology hails or interpellates concrete individuals as concrete subjects, through the functioning of the category of the subject

Althusser (1971:190)

Ideological state apparatus (ISA), is a theoretical concept developed by (Algerian born) French philosopher Louis Althusser which is used to describe the way in which structures of civic society – education, culture, the arts, the family, religion, bureaucracy, administration etc serve to structure the ideological perspectives of society, which in turn form our individual subject identity. According to Althusser, ‘the category of the subject . . . is the category constitutive of all ideology’ (214:188). In other words, we are socially constructed and what socially constructs us is ‘despite its diversity and contradictions . . . the ruling ideology, which is the ideology of ‘the ruling class’,’ (2014:245)

Althusser noted that individuals often believe that they are ‘outside ideology’ and suggested the notion of ‘interpellation‘ as a way to recognise the formation of ideology. In that ideology ‘acts’ or ‘functions’ in such a way as to recruit subjects among individuals. In other words, the way in which society calls / addresses / hails you is interpellation, which is the way in which your subject identity is formed and which, more often than not, corresponds to the dominant ideology.

‘Ideology ‘acts’ or ‘functions’ in such a way to ‘recruit’ subjects among individuals . . . through the very precise operation that we call interpellation or hailing.
