A new emphasis in epistemology is burgeoning, known by the phrase ‘the epistemology of disagreement’. The object of investigation is the situation where the two combatants of a disagreement are equally well situated epistemologically. Central questions include whether peer epistemic conflict reduces the support one has for one's belief, whether the reduction should be understood on internalist or externalist lines, and how often such peer conflict happens. The main objective in the first two sections will be to provide background by bringing key points of contention to the surface in the recent epistemologies of disagreement both in mainstream epistemology and in religious epistemology. A final section asserts that epistemic externalism in religious epistemology doesn't easily escape the challenge of epistemic, peer, religious disagreement.
