Given the hundreds of articles and books that have been written in epistemology over the span of just the past few decades, relatively little has been written specifically on epistemic responsibility. What has been written rarely considers the nature of epistemic responsibility and its possible role in epistemic justification or knowledge. Instead, such work concerns philosophical analyses and arguments about related concepts such as epistemic virtues or duties, rather than epistemic praiseworthiness and blameworthiness.2 It is epistemic responsibility in the blameworthiness and praiseworthiness senses that is the primary concern of this paper, though the duty sense of epistemic responsibility is explored in terms of its pertinence to epistemic virtue. What is epistemic responsibility? And what, if anything, is its relationship to justification and knowledge?
