Reductionism as an approach to the epistemology of testimony places certain demands on the recipient of testimony that its competitor, antireductionism, does not. After laying out the two approaches and their respective demands on the recipient of testimony, I argue that reductionism also places certain anonymity-shedding demands on the testifier that antireductionism does not. The difficulty of deciding between the approaches leads to a worry about the extent to which the current state of affairs in epistemology can offer secure advice (...) on the sorts of anonymity constraints that a networked society should place on its testifiers. This worry can be mitigated, I further argue, upon recognition of the fact that the two approaches stand on common ground when it comes to cases of known testimonial conflict. (shrink)
