| 15164 | We seem to base necessities on thought experiments and imagination [Sidelle] |
| 21544 | It seems that when a proposition is false, something must fail to subsist [Russell] |
| 21539 | Excluded middle can be stated psychologically, as denial of p implies assertion of not-p [Russell] |

| 21535 | Objects only exist if they 'occupy' space and time [Russell] |
| 15184 | Causal reference presupposes essentialism if it refers to modally extended entities [Sidelle] |
| 15172 | Clearly, essential predications express necessary properties [Sidelle] |
| 15181 | Being a deepest explanatory feature is an actual, not a modal property [Sidelle] |
| 15173 | That the essence of water is its microstructure is a convention, not a discovery [Sidelle] |
| 15185 | We aren't clear about 'same stuff as this', so a principle of individuation is needed to identify it [Sidelle] |
| 15175 | Evaluation of de dicto modalities does not depend on the identity of its objects [Sidelle] |
| 21533 | Contingency arises from tensed verbs changing the propositions to which they refer [Russell] |
| 15032 | Necessary a posteriori is conventional for necessity and nonmodal for a posteriority [Sidelle, by Sider] |
| 15179 | To know empirical necessities, we need empirical facts, plus conventions about which are necessary [Sidelle] |
| 15171 | The necessary a posteriori is statements either of identity or of essence [Sidelle] |
| 15167 | Empiricism explores necessities and concept-limits by imagining negations of truths [Sidelle] |
| 15177 | Contradictoriness limits what is possible and what is imaginable [Sidelle] |
| 15176 | The individuals and kinds involved in modality are also a matter of convention [Sidelle] |

| 15183 | 'Dthat' operates to make a singular term into a rigid term [Sidelle] |
| 21537 | I assume we perceive the actual objects, and not their 'presentations' [Russell] |
| 15165 | A priori knowledge is entirely of analytic truths [Sidelle] |
| 21532 | Full empiricism is not tenable, but empirical investigation is always essential [Russell] |
| 21542 | Do incorrect judgements have non-existent, or mental, or external objects? [Russell] |
| 21541 | The complexity of the content correlates with the complexity of the object [Russell] |
| 15168 | That water is essentially H2O in some way concerns how we use 'water' [Sidelle] |
| 15166 | Causal reference seems to get directly at the object, thus leaving its nature open [Sidelle] |
| 15182 | Because some entities overlap, reference must have analytic individuation principles [Sidelle] |
| 21543 | If p is false, then believing not-p is knowing a truth, so negative propositions must exist [Russell] |
| 6017 | Nomos is king [Pindar] |
| 15178 | Can anything in science reveal the necessity of what it discovers? [Sidelle] |
