Defending virtue epistemology: epistemic dependence in testimony and extended cognition

This paper provides an account of how virtue epistemology can accommodate knowledge acquired through testimony and extended cognition. Section 1articulates the characteristic claim of virtue epistemology (VE), and introduces the issues discussed in the paper. Section 2details a related pair of objections to VE: that it is unable to accommodate cases of knowledge through (1) testimony and (2) extended cognition. Section 3reviews two different virtue epistemologies and their responses to these objections presented in Greco (Achieving knowledge, Cambridge University Press, Cambridge,2010; Philos Phenomenol Res 85(1):1-26,2012). Considerations are presented for why both of these accounts and responses are inadequate. Because of this, I suggest that it is unlikely that an analysis of theattributionrelation will provide an adequate response to the objections. Section 4advocates for a revised VE and a different way of dealing with the objections, which accommodates how agents are sometimes epistemically dependent on external sources. The central claim, for which a novel argument is presented, is that in some cases of knowledge (including the troublesome cases) the success is attributable to the abilities of an information system of which the knower is a part. This requires an important revision to traditional VE, but the characteristic claim of VE still holds true-every instance of knowledge is an instance of success attributable to ability. Thus, VE's solutions to problems concerning the nature and value of knowledge are secured.
