Epistemic norms play an increasingly important role in many current debates in epistemology and beyond. Paramount among these are debates about belief, action, and assertion. Three primary questions organize the literature. What epistemic requirements constrain appropriate belief? Whatepistemic requirements constrain appropriate assertion? What epistemic requirements constrain appropriate action? With the tremendous but disparate growth of the literature on epistemic norms, the time is ripe for a volume bringing together papers by established and emerging figures, with an eyetoward the interconnections among our three questions. That is precisely what this volume seeks to do.
