Epistemic Structure in Non-Summative Social Knowledge

How a group G can know that p has been the subject of much investigation in social epistemology recent years. This paper clarifies and defends form non-supervenient, non-summative knowledge: even if none members knows p, whether or not does locally supervene on mental states G. Instead, we argue what is central to knowing an epistemic structure functioning appropriately accord with action-related purposes group, this may include non-agential elements such as devices retain process information. We objections knowledge given by Jennifer Lackey do fact succeed undermining view, but help clarify nature knowledge. The main upshot our response Lackey’s groups put their into action ways often differ from how individuals do, epistemologists should be careful notice these differences, especially insofar themselves employing various epistemically-relevant devices.
