According to a broad historical and contemporary consensus, ideology resides in the mind, as a sort of belief system gone wrong. Recently, however, a minority view has challenged this cognitivist consensus by highlighting ideology’s social function. This group of authors, including Rahel Jaeggi, Karen Ng, Robin Celikates, and Sally Haslanger, underline the importance of analyzing ideology through the lens of our social practices. We think these challengers move the conversation about ideology in the right direction, but their views still suffer (...) from some weaknesses – weaknesses that we think an existential-phenomenological account of ideology can overcome. We develop such an account here. We conceive of ideology as a set of modes of being-with that attack our normative competence by placing us under unwarranted normative pressure, changing our normative stance to benefit some political group. We offer a four-fold account of normative competence and illustrate how ideology, understood in our terms, attacks it. Finally, we show that our approach shares the strengths but not the weaknesses of the minority view. (shrink)
