At that time the postulation of new abstract objects, such as Fregean senses or other intensional objects, in order to explicate a certain notion of synonymy seemed an unacceptable move for someone with nominalist leanings such as Quine and a purist such as White. For Quine, an explication of “synonymy” or “analyticity” and the like should rather be given in behavioristic terms. The explication should tell us in what way “analyticity” and “synonymy” make a difference in speaker behavior. To learn that the difference lies in postulated abstract objects did not seem to explicate the notions in any promising way.
