The subject ("self") is like a filter of predetermined shape, i.e. the identity of the subject which has been prescribed by the preexisting
social structure of family/culture, which takes on the residue of various ideologies as they pass through it; this happens in light of what Althusser claims to be the ambiguous nature of the term "subject": that is refers to a "free subjectivity, a center of initiatives, author of an responsible for its actions" and/or that is refers to "a subjected being who submits to a higher authority, as is therefore stripped of all freedom except that of freely accepting his submission" (303). --Melissa

Ideology, a two-fold material element, both constitutes (via interpellation) the human/individual subject with its illusions of (or
ideologies about) the individual's relation to things, and is co-dependent on the (human) subject (who assumes the posture and enacts or compels the rituals) for its very existence. --Mike

(Klages on Althusser)
Althusser's philosophical notion of interpellation describes the transformation of the individual into a
subject, where subject is a function of a Subject with a capital S, or "the structural possibility of
subjecthood";‘ drawing connections between Marxism and psychoanalysis, the Subject (with a capital S) and the
Lacanian "Other" are twin principles: by and through them identity (ideological or social) is fashioned.--Yana
