Even if there are coextensive predicates among the hundred, could we still insist upon a full hundred fictitious objects, all different, for them to name?
But why not a full hundred, thus letting coextensive predicates name different objects?
If this much is granted, then our question ('May coextensive predicates name different objects?')
But any such language is extensional; that is, coextensive predicates are interchangeable salva veritate.14 No true sentence in the language can become false when an occurrence of a predicate is supplanted by a coextensive predicate.
A consequence is that extensionality lapses; coextensive predicates cease to be interchangeable.
