This chapter critically evaluates whether Habermas's critique of colonization in "The Theory of Communicative Action" can fulfil the requirements of an immanent social critique. I argue that Habermas develops the distinction between system and life-world to provide a basis for immanent critique, but that he ultimately does not clearly distinguish between a normative and a functionalist model of immanent critique. As an alternative, I develop a model of a fully normative immanent critique of colonization.
