|Semantics of possible worlds: is an expression for a theory that defines sentence meaning as the set of worlds in which this sentence is true. See also possible worlds, rigidity, semantics, propositions, meaning, modal logic, counterpart-theory, modal realism, necessity, possibility._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Property/Denotation/possible world/possible world semantics/Field: E.g. "Russell is bald" is true in every world w where Russell exists (denoted by "Russell" in the actual world) and where Russell is bald (i.e. has the property for which "bald" stands in the actual world). - N.B.: "stand for": we must now understand it like this: a predicate does not stand for a set (its extension), but for a property that exists in the actual world.
Problem: relation between predicates and properties.
Problem: Properties determine extensions of the predicates, but are not determined by them.
Solution: within the possible world semantics: causal theory of the reference.
Problem: we are not coming into contact with all extensions of "bald" solution: property instead of extension - or the extension is determined by a property.
Then what is associated with the predicate is not its extension, but a property. - The relation can be causal or non-causal._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
