Several recently defended views give a central role in the nature of epistemic justification to some kind of authority. In one version, the authority is oneself were one to reflect extremely carefully; in another, the authorities are experts in reasoning; and in the third, the expert is God (or “Nature”). This chapter argues that they all have the sort of explanatory flaw that is famously discussed in Plato's Euthyphro.
