Radical epistemology, theory choice, and the priority of the epistemic

Beliefs based on pernicious ideology are widespread, and they often have harmful consequences. Attempts to solve the problems these beliefs cause could benefit from epistemological work on them, so it is heartening to see more epistemologists turning to study ideological beliefs. In this paper, I discuss one recent approach, radical epistemology, which has two aims: (1) offering structural explanations of epistemic justification and (2) putting these explanations to work in opposing ideology. While I share radical epistemologists’ opposition to pernicious ideology, I argue that their position is untenable because it gives rise to a vicious circularity. Its core commitment maintains that theorists’ choice between competing epistemological theories should be guided by their moral and political commitments. These commitments themselves, however, are susceptible to reasonable disagreement and thus stand in need of defense. To defend them, radical epistemologists must employ the very theories those commitments are supposed to undergird. I call this the problem of theory choice and conclude that radical epistemologists cannot solve it. But we shouldn’t despair: the time-honored tools of non-radical epistemology offer all we need to successfully theorize about and combat bad ideology.
