Is Normative Uncertainty Irrelevant if Your Descriptive Uncertainty Depends on It?

According to ‘Excluders’, descriptive uncertainty – but not normative matters what we ought do.

The aim of this paper is determine whether the phenomenon poses decisive for Excluders. I argue existing arguments fail show this, and that, while stronger ones be found, Excluders escape them.
