| 6873 | Coherent justification seems to require retrieving all our beliefs simultaneously [Goldman] |

| 17701 | Possible worlds semantics has a nice compositional account of modal statements [Mares] |
| 17702 | Unstructured propositions are sets of possible worlds; structured ones have components [Mares] |
| 17708 | Maybe space has points, but processes always need regions with a size [Mares] |
