Political epistemology has become a popular field of research in recent years. It sets itself the ambitious task to intertwine epistemology with social and political theory in order to do justice to the relationships between truth and politics, or reason and power. Yet many contributions either expand arguments and concepts from traditional epistemology to political phenomena or use existing theories and frameworks from social and political theory to address the politics of epistemological questions. The former approach (prominent, e.g., in the (...) epistemic injustice debate) leads to an epistemisation of political phenomena and concepts coupled with their de-politicization, the latter approach (prominent, e.g., in Frankfurt School critical theory) leads to a politicization of epistemic phenomena and concepts coupled with their de-epistemisation. Instead, it is argued that political epistemology requires reworking even basic concepts, due to its three foundational commitments: It is committed to the claim that socio-material conditions of existence matter epistemically (minimal materialism), to the self-reflection of the socio-material conditions of political epistemology's own arguments and theories (radical self-reflexivity), and to a specific form of epistemic humility (epistemic non-sovereignty). Using the notion of normativity as an exemplary problem, the article closes by highlighting the difficulty of maintaining these three commitments. (shrink)
