 Perhaps the most popular argument for Ontological Innocence is the one to which I now turn. In its simplest form, this argument is based on our intuitions about ontological commitments. When you assert  (18),  you don’t have the feeling that you are committing yourself ontologically to a collection or to any other kind of “set-like” object. Nor do you have any such feeling when you assert the Geach-Kaplan sentence or any other translation of a sentence of PFO or PFO+ into English. Or so the argument goes.
