This book explores the epistemic side of racial and sexual oppression. It elucidates how social insensitivities and imposed silences prevent members of different groups from listening to each other. The social epistemology developed in recent decades represents a welcome advance on the dead-end of Cartesian individualism. But the social has too often been conceived of without centering social oppression, and all the noetic complexities that come with it. In this richly detailed and wide-ranging text, Jose Medina locates the epistemological project squarely where it belongs: in societies of privilege, subordination, and radical group differentiation. Drawing on feminism, critical race theory, and queer theory, he shows with unprecedented thoroughness that we need to develop the cognitive virtues necessary to overcome active ignorance, epistemic injustice, and structural group insensitivity in sum, the problems not of a conveniently sanitized epistemic 'Twin-Earth' but the disordered world in which we all actually live.
