Peter van Inwagen on Possible Worlds - Dictionary of Arguments

Schwarz I 41
Def Possible Worlds/Lewis: early definition: possible worlds are ways how things could be.
Van InwagenVs: these are rather properties than concrete universes (StalnakerVsLewis, RichardsVsLewis: ditto).
Lewis: later: worlds correspond to ways how things could be.
Schwarz: but we do not necessarily have to create special entities for it. They could also be grammatical illusions. Even if one considers possible worlds as entities, one does not determine for a long time what kind of entities they are.
>Modal realism/Inwagen.
