| 8554 | Possible difference across worlds depends on difference across time in the actual world [Shoemaker] |
| Full Idea: The ways in which a given thing can be different in different possible worlds depend on the ways in which such a thing can be different at different times in the actual world. | |
| From: Sydney Shoemaker (Causality and Properties [1980], §05) | |
| A reaction: Where change in a thing is possible across time in the actual world seems to require a combination of experiment and imagination. Unimaginability does not entail necessity, but it may be the best guide we have got. |
