In general, epistemic internalists hold that an individual’s justification for a belief is exhausted by her reflectively accessible reasons for thinking that the contents of her beliefs are true. Applying this to the epistemology of testimony, a hearer’s justification for beliefs acquired through testimony is exhausted by her reflectively accessible reasons to think that the contents of the speaker’s testimony is true. A consequence of internalism is that subjects that are alike with respect to their reflectively accessible reasons are alike (...) with respect to what they have justification to believe. Testimony should be thought no different: hearers that are alike with respect to reflectively accessible reasons to think that a speaker’s testimony is true are alike with respect to their justification for beliefs based upon that testimony. But it has been recently argued that this view faces powerful counterexamples. So the central question is this: assuming that a hearer can acquire justification to believe a proposition through the testimony of a speaker, can epistemic internalism provide the resources to explain how such justification is possible? My aim in this paper is to address these counterexamples, and in so doing, defend epistemic internalist accounts of testimony. (shrink)

According to Alvin Goldman, reliabilists need to distinguish between unconditionally and conditionally reliable processes. The latter category is used to account for processes such as reasoning or memory. In this paper, I will argue that Goldman’s account of conditional reliability needs substantial revision in two respects. First, conditional reliability must be reinterpreted in terms of dependent reliability to avoid serious problems. Second, we need a more liberal account that allows dependently reliable processes to operate not only on doxastic but also (...) on non-doxastic input. Thinking this way advances the explanatory power of reliabilism significantly. (shrink)

Recent developments in technologically enabled social cognition call for a rethinking of many aspects of human cognition. According to the hypothesis of extended cognition, we must revise our psychological categories by eliminating allegedly superficial distinctions between internal cognition and external processes. As an alternative to this proposal, I outline a hypothesis of outsourced cognition which seeks to respect distinctions that are operative in both folk psychology and the social and cognitive sciences. According to this hypothesis, the cognitive states and processes (...) of the individual are substantially and explanatorily distinct from the relevant external states and processes. In consequence, the individual remains a cognitive unit that is both central and indispensable in the explanations of cognitive science. As a case study, I consider the epistemology of testimony. I will argue that important epistemological categories may be preserved by adopting the hypothesis of outsourced cognition over the hypothesis of extended cognition. Moreover, I will argue that the outsourced cognition hypothesis deepens the problems that beset an extended epistemology of testimony. (shrink)
