This article is not about Acadia per se, but about a domain that must concern it precisely because of the role history plays there, that is epistemology of history. It examines it through one of its research programs: naturalized epistemology of history. We identify by means of an historical and documentary inquiry the issues raised by the naturalization of epistemology and consider, in a meta-epistemological perspective, how naturalized epistemology of history conceptualizes the very exercise of epistemology of history. We ask if the (re)conceptualization of epistemology of history carried by the naturalized program―for which history is both an object and a method―could renew the dialogue between two knowledge universes that have been largely ignoring themselves, the one of historians and the one of philosophers, and have been preoccupied by what making historical knowledge means. In doing so, our study is part of a larger ongoing reflection on the relation between the discipline of history and the theory of history.
