This article focuses on Stuart Hall’s reading of Louis Althusser’s main theoretical works. Since the early 1970s, Hall has undertaken a critical confrontation with Althusser’s ‘structural Marxism’, rescuing those useful concepts to think cultural difference and identity, without failing to criticize his ‘superstructuralist’ interpretation of Marx. However, what Hall will retain as Althusser’s most important contribution is, above all, his theory of ideology. In this context, I follow an idea formulated by Hall that could be read as summarizing the theoretical (...) and political scope of Althusser’s contribution to Cultural Studies: ‘he enabled me to live in and with difference’. By complicating classical interpretations schemes in the Marxist tradition, Hall’s Althusser may be read as a ‘thinker of difference’ who opens up a whole research program to reconsider class conflicts as traversed (or ‘overdetermined’) by gender, racial or colonial conflicts.
