Unicorn/Non-existence/Goodman: Primary Extension: All scores never listed have the same (i.e. no) performances as performance objects. Like Unicorn images and Centaur images. In an indirect sense in which they are images of different things they are also the scores of "various works". In none of the cases is a difference in the primary extension.
We do not share fictional images and descriptions on the basis that we have tested something what they depict or describe, but just as we divide furniture into chairs - on that basis that we have learned the use of predicates.
