Meta Ontology

metaphysics of modality. So, we read David Kaplan in 1967: I'll even let you peep through my Jules Verne-o-scope [into another possible world G]. Carefully examine each individual, check his fingerprints, etc. The problem is: which one is our Bobby Dylan---of course he may be somewhat changed, just as he will be in our world in a few years\textellipsisOur problem is [to] locate him in G (if he exists there). The task of locating individuals in other worlds is the problem of determining transworld heir lines. I will flatly assert that this problem is the central problem of philosophical interest in the development of intensional logic. The clearest statements of the "problem" came from those who thought that, ultimately.
