 There is also room for the priority pluralist to claim a tu quoque, by arguing for the possibility of “worldless junk,” which is something every whole of which is a proper part, so that there is no ultimate whole. In this vein Bohn (2009) argues that junk has an equal claim to gunk for being metaphysically possible. If there are both gunky as well as junky metaphysical possibilities—and even “hunky” possibilities that are both gunky and junky—then one will not be able to appeal to either ultimate parts or an ultimate whole consistently across metaphysical possibilities. (As with tu quoque replies generally, the rejoinder from gunk leaves open what went “wrong” in the original argument of  14–16.[47])
