Proxy: A proxy is a function that maps the objects of one theory onto the objects of another theory, while preserving the truth values of all sentences. This means that we can substitute the objects of one theory for the objects of another theory without changing the truth values of any of our statements. See also Truth values, Functions, Sentences, Substitution, Expressions._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Hartry Field on Proxy - Dictionary of Arguments
II 41 Property/denotation/possible world/Field: E.g. "Russell is bald" is true in any possible world w, where Russell exists (denoted by "Russell" in the actual world) and is bald (i.e. has the property for which "bald" stands in the actual world). N.B.: "stand for": we must now understand them in that way that a predicate does not stand for a set (its extension), but for a property that exists in the actual world. >Denotation, >Extensions, >Predicates, >Properties. Problem: the 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. >Causal theory of the reference. Problem: we are not coming into contact with all extensions of "bald". - Then what is associated with the predicate is not its extension, but a property. The relation can be causal or non-causal. >possible world-semantics,> cross-world identity._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
