Is Trust an Epistemological Notion?

Abstract : Although there is widespread agreement that our epistemic dependence on other people's knowledge is a key ingredient of our cognitive life, the role of trust in this dependence is much more open to debate. Is trust in epistemic authority—or “epistemic trust” for short—an epistemological notion in any sense, or is it simply a bridge-concept that connects our epistemological concerns to moral issues? Should we depict it in terms of the more familiar sociological notion of trust as a basis for cooperation?
