16951 | It was realised that possible worlds covered all modal logics, if they had a structure [Dummett] |
16953 | Relative possibility one way may be impossible coming back, so it isn't symmetrical [Dummett] |
16952 | If something is only possible relative to another possibility, the possibility relation is not transitive [Dummett] |
16960 | If possibilitiy is relative, that might make accessibility non-transitive, and T the correct system [Dummett] |
16958 | In S4 the actual world has a special place [Dummett] |
17306 | If ground is transitive and irreflexive, it has a strict partial ordering, giving structure [Schaffer,J] |
17304 | As causation links across time, grounding links the world across levels [Schaffer,J] |
16957 | Possible worlds aren't how the world might be, but how a world might be, given some possibility [Dummett] |
