    • In seeking a satisfactory formulation of materialism, it helps to employ the notion of a possible world''. Possible worlds are plausibly construed not literally as universes other than the single real universe (i.e., not as ''cosmoi'''''), but rather as ''total ways the cosmos might be''?—?i.e., maximal ''properties'' instantiable by the single real world (the single cosmos). On this usage, the item designated as the actual world?—?considered as one among the various possible worlds?—?is not itself the cosmos either, but rather is the total cosmos-instantiable property that is ''actually'' instantiated by the cosmos. But it will be convenient in practice to speak as though the actual world is the cosmos and as though other possible worlds are other such ' cosmoi ?—?a harmless enough manner of speaking, as long as one bears in mind that it is not intended literally.
