Having now distinguished these principles, we can consider whether either provides an argument against haecceitism. As Lewis (1986: 224) notes, PII-Objects leaves haecceitism untouched, since it is compatible with the possibility of qualitatively indiscernible worlds that differ haecceitistically. And, while PII-Worlds rules out qualitatively indiscernible worlds rather than objects within worlds, Lewis’ cheap haecceitism still permits the representation of maximal possibilities that differ haecceitistically even without positing qualitatively indiscernible worlds. It looks, then, like PII is not a plausible starting point for a case against Possibility Haecceitism within Lewisian Modal Realism.
