Subject and Predicate in Logic and Grammar Quotes

Because Russell confused meaning with mentioning, he thought that if there were any expressions having a uniquely referring use, which were what they seemed (i.e. logical subjects) and not something else in disguise, their meaning must be the particular object which they were used to refer to. Hence the troublesome mythology of the logically proper name.”
