Single Idea 16411

[catalogued under 10. Modality / E. Possible worlds / 3. Transworld Objects / c. Counterparts]

Full Idea

Nothing can be in two places at once. If other possible worlds are really other universes, then clearly, you and I cannot be in them if we are here in this one.

Gist of Idea

If possible worlds really differ, I can't be in more than one at a time

A Reaction

This can be sensibly expressed without possible worlds. I can't embody my other possibilities while I am embodying this one (I'm too busy). Insofar as possible worlds are a good framework, they are just a precise map of common sense.
