Abstract

Epistemic standards purport to tell us under what conditions we should adopt specific beliefs. In the scientific case, we might understand an epistemic standard as telling us what beliefs we should or even must adopt when faced with such-and-such evidence. It is an open question whether and to what extent science, or scientists, form beliefs based upon standards so construed. Epistemic relativism gives two strong arguments against a robust role for epistemic standards in science. This paper assesses these arguments and argues that even if we accept them, epistemic standards play a strong, normative role and that failure to adhere to epistemic standards, in a sense to be clarified, risks irrationality. To make this argument, we must abandon the idea that standards determine in a strong sense what beliefs scientists must adopt and instead think of them as a guide for choosing between beliefs. If we think of standards in this way, then they can play a role in rational scientific discourse. This conception of standards is inspired by Kuhnian values and helps arbitrate between relativism and more rational conceptions of evidence and justification. The Chemical Revolution provides illustration of this view.
