| 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.
