| 11160 | Simple modal essentialism refers to necessary properties of an object [Fine,K] |
| 11158 | Essentialist claims can be formulated more clearly with quantified modal logic [Fine,K] |
| 11167 | Metaphysical necessity is a special case of essence, not vice versa [Fine,K] |

| 13239 | Judgement is always predicating a property of a subject [Beall/Restall] |
| 13248 | We can rest truth-conditions on situations, rather than on possible worlds [Beall/Restall] |
| 13233 | Propositions commit to content, and not to any way of spelling it out [Beall/Restall] |
| 11172 | The meaning of 'bachelor' is irrelevant to the meaning of 'unmarried man' [Fine,K] |
