 Returning to the priority argument, there are two types of priority cases to consider: cases in which the prior fact is fundamental, and cases in which neither the prior nor posterior facts are fundamental. J. Wilson (2014, 2016a) develops a proposal according to which a primitive notion of fundamentality plays the direction-fixing role in priority cases of the first type. And this primitive notion and other grounding-free considerations (e.g., modal considerations) play the direction-fixing role in cases of the second type. (For non-skeptical rejoinders, see Cameron 2016 and Raven 2017.)
