II 72 Definition true/truth/semantics of possible worlds/Cresswell: a sentence is true in a possible world iff this world is in the set of worlds, which is its intension (of the sentence). >Intensions, >Extensions. Cresswell: therefore it can be said that the extension of the theorem is its truth value. >Truth Value/Frege. II 163 Possible World Semantics/possible world/FieldVsPossible World Semantics/Cresswell: (Field 1978(1), 40) the use of possible worlds binds someone to a general concept of synonymy. >Synonymy. II 163 Possible World Semantics/Cresswell: allows an immediate access to terms such as entailment and inconsistency. That is, meaning postulates are superfluous. >Meaning postulates. II 164 Def Entailment/Possible World Semantics: is simply the class inclusion in the set of possible worlds. >Entailment. Def contradiction: something that is true in no possible world. >Contradictions, >Impossible worlds. 1. Field, H. 1978. Mental Representation. In: Erkenntnis 13.
