Improper name/Quine: (= descriptions- only real names allow the substitution that can be found in the indistinguishability of identical.
Improper names: lead to more complex form: E.g. "among the Roman orators there is a major one, and he denounced Catiline that".
E.g. "Just one number counts the planets and it is more than seven"/Russell: here is only 7 a real name - hence these sentences may not be sentences in a conclusion of the principle of indistinguishability of the identical.

QuineVs:. problem : range: the marks must be eliminated, so that in the new wording no part corresponds with them.
