| 4592 | If you can have the boat without its current planks, and the planks with no boat, the planks aren't the boat [Heil] |

| A reaction: Thus Queen Elizabeth II has to be the result of that particular birth, and from those particular parents, as Kripke says? The inverse may not be true. Do twins have a single origin? Things that fission and then re-fuse differently? etc |
