Grice and the neo-Meinongians

From M. R.'s online 'nonexistent objects', Stanford Encyclopedia:

"Most “Neo-Meinongians” (as one could call them) adopt one of the following three strategies in order to free Meinongian object theory from inconsistencies and counterintuitive consequences:
i.The other worlds strategy makes use of the assumption of merely possible (and even impossible) worlds. (See Priest 2005.)
ii.The nuclear-extranuclear strategy consists in a distinction between two kinds of properties.[17]
iii.The dual copula strategy consists in a distinction between two relations between properties and individuals.[18]."
