 A second reason why one might challenge 25 is a challenge to the right-to-left direction (from free recombination to priority pluralism). While priority pluralism arguably entails free recombination, it is not obvious that priority monism should entail any lack of free recombination. Just because multiple concreta have a common ground in the cosmos does not mean that these concreta cannot be freely recombined. Perhaps modal constraint entails ontological connection; but it is not obvious why ontological connection should entail modal constraint. If so then the priority monist might have a special flexibility with respect to whether or not there is free recombination.
