Abstract

Can a reliabilist theory of justified belief be extended to account for justified credence? In exploring this question, this paper first takes as its target Tang’s reliabilist account of justified credence, which is inspired by William Alston’s “indicator reliabilism” about justified belief. I point out a neglected shortcoming in Tang’s account, which concerns its failure to properly explain degrees of justification. Fortunately, Alston’s epistemology contains the resources which can be developed to remedy this defect. The central idea here is that the justificatory status of a credence can not only be defeated by a subject’s own perspective, but also be enhanced by that. Finally, it is argued that this idea applies to beliefs as well.
