 Since Priority monism turns out equivalent to Priority monism (cosmic) which turns out equivalent to \(Bu\), and Priority pluralism turns out equivalent to Priority pluralism (partial) and so equivalent to \({\sim}Bu\), Priority monism and Priority pluralism turn out to be contradictories. They are exhaustive and exclusive conceptions of the basic concreta. Given the tiling constraint, Priority monism and Priority pluralism turn out to be exhaustive and exclusive conceptions of how to carve nature at the joints.
