 Cases like Hypoxia therefore leave us with three choices. If we say that Aisha should maintain confidence in G, but reduce confidence that it’s rational for her to belief G, we must explain why epistemic akrasia can be rational. If we say she should maintain confidence in G and dismiss the possibility of hypoxia, we must explain why dogmatism can be rational. And if we say she should reduce confidence in G, we must explain how this type of defeat works, and how it fits into our broader theory of rationality. Let us now return to that last question.
