The Spectra of Epistemic Norms

I argue that there is a wide variety of epistemic norms, distributed along two different spectra. One spectrum runs from the ideal to the practical and concerns the extent to which it is possible to follow the norm given our cognitive and epistemic limitations. The other spectrum runs from thin to thick and concerns the extent to which the norm concerns facts about our beliefs over and above the content of the belief. Many putative epistemic norms, such as truth and various conceptions of justification, can be found at different points on the spectra. There is no single obvious privileged point from which to say any of these norms is more fundamental than the others, though there may be some reason to doubt that some of the norms are intrinsically interesting.
