 As a third illustration, let the unit \(u_2 =\) individual token. The monist for \(t_1\) counted by \(u_1\) (the substance monist, e.g., the materialist) might still be a pluralist for \(t_1\) counted by \(u_2\) (for concrete objects counted by tokens). For instance, she might hold that there exist many concrete object tokens (existence pluralism), while maintaining that these are all material objects. Likewise the pluralist for \(t_1\) counted by \(u_1\) might be a monist for \(t_1\) counted by \(u_2\). For instance, she might hold that there is only the one “world-person” with two highest types of property, physical and mental. (These examples show the need to relativize monism to a unit.)
