阿尔都塞的意识形态理论是近年来先锋理论最为流行的灵感来源之一。意识形态从特拉西的客观主义到被马克思视为德国唯心主义旧哲学，乃至泛指整个上层建筑，其定义迄今众说纷纭。阿尔都塞在结构主义和马克思主义交相辉映的20世纪六七十年代，立足科学区分所谓镇压性国家机器和意识形态国家机器，由此提出一整套意识形态理论，其影响远非科学主义可一言蔽之。意识形态没有历史，意识形态无所不在，意识形态就是主体性，我们通过观照自己的意识形态镜像获得身份。这些阿尔都塞意识形态理论的基本命题，其后续意义很显然超越了阿尔都塞本人的期望。它们是不是在讲授另一个乌托邦故事？

Althussers description of ideological state apparatuses give much inspiration to recent avantguards theoriesSince ADTracy coined the term “ideology，” there are too many definitions concerning what the “science of idea” means，including Karl Marxs famous saying that ideology is nothing but German idealismFor Althusser，ideological practice consists of a kind of institutions called “ideological state apparatuses，” which include family，school，media，religion etc,and differentiate from the so called “repressive state apparatuses，” iepolice or prisonIt indicates more than a scientific structuralism even during the red 1960s and 1970s“Ideology has no history，” “ideology is the very subjectivity，” and yet，are all of these typical Althussrian propositions telling another Utopian story?
