 That said, one might expect the priority pluralist to challenge 14, for one of the following two reasons. First, the priority pluralist might (on considering gunk, and maintaining her thesis that the parts are prior to the whole) declare that nothing is basic in gunky worlds. Things get ever more basic without limit. But this would run counter to ontological foundationalism, and the widespread idea that being needs an ultimate ground (§3.1). This is no longer priority pluralism but priority nihilism, as least for gunky worlds.
