Abstract: Colonial unknowing endeavors to render unintelligible the entanglements of racialization and colonization, occluding the mutable historicity of colonial structures and attributing finality to conquest and dispossession. Colonial unknowing establishes what can count as evidence, proof, or possibility—aiming to secure the terms of reason and reasonableness—as much as it works to dissociate and ignore. This essay introduces the issue theme, analyzing epistemologies of unknowing by engaging critical indigenous thought, critical race theory, postcolonial feminist theory, critical disability studies, queer theory, and women of color feminism in order to trouble theorizations of settler colonialism as a stand-alone analytic.
