Single Idea 11109

[filed under theme 10. Modality / E. Possible worlds / 1. Possible Worlds / e. Against possible worlds ]

Full Idea

Any other realms that happened to exist would just be scattered parts of the actual world, not entire worlds at all. It would just happen that physical reality was fragmented in this remarkable but modally inconsequential way.

Gist of Idea

If other worlds exist, then they are scattered parts of the actual world

Source

Michael Jubien (Analyzing Modality [2007], 1)

Book Ref

'Oxford Studies in Metaphysics vol.3', ed/tr. Zimmerman,Dean W. [OUP 2007], p.100

A Reaction

This is aimed explicitly at Lewis's modal realism, and strikes me as correct. Jubien's key point here is that they are irrelevant to modality, just as foreign countries are irrelevant to the modality of this one.

11108 Your properties, not some other world, decide your possibilities [Jubien]
11111 Modal truths are facts about parts of this world, not about remote maximal entities [Jubien]
11109 If other worlds exist, then they are scattered parts of the actual world [Jubien]
11106 If all possible worlds just happened to include stars, their existence would be necessary [Jubien]
11112 Possible worlds just give parallel contingencies, with no explanation at all of necessity [Jubien]
11113 Worlds don't explain necessity; we use necessity to decide on possible worlds [Jubien]
11115 'All horses' either picks out the horses, or the things which are horses [Jubien]
