Epistemic Relativism and the Gettier Problem

The aim of this article is to present a variant of epistemic relativism that is compatible with a language practice especially popular among scientists. We argue that in science, but also in philosophy, propositions are naturally ‘relativized’ to sets of hypotheses or theories, and that a similar language practice allows one to interpret canonical problems of epistemology. We apply the model to Gettier’s problem, and derive a condition under which counterexamples à la Gettier to Plato’s account of knowledge do not arise. We argue that these findings give further content to a well-known result by Zagzebski (1994). Our interpretation points to a type of epistemic relativism having links with contextualism in epistemology, and perspectivism in philosophy of science.
