Abstract
Does Pegasus fly? We believe most of you would answer “yes”without thinking it actually exists in this world. On the other hand,W. V. Quine argued that if we let some existential formula be true,we have to commit the existence of the object which is essential to let the formula be true. So that it can be said that there is a gap between Quine’s ontological argument and ontology in our daily life. Our goal in this paper is to fill the gap and expand Quine’s argument by relying on Meinongian philosophy, especially G. Priest’s neo-Meinongianism called Noneism, which admits different types of existence.
