Louis Althusser is remembered today as the scourge of humanist Marxism, but that was his later incarnation, an identity formed by years grappling with the intellectual inheritance of Hegel and Catholicism. The Spectre of Hegel collects the writings of the young Althusser, before his final epistemological break with the philosopher’s work in 1953. Including his famed essay ‘Ideology and Ideological State Apparatuses’, The Spectre of Hegel gives a unique insight into Althusser’s engagement with a philosophy he would later renounce.
