 Existence pluralism is the view that there is more than one thing. Certainly existence pluralism is the standard view—even among metaphysicians. Indeed, most people think that there are a great many things. The conjunction of the Umbrella View and existence pluralism entails that there is more than one object. But if one thinks there are a great many things, one might also think that they are not all objects. And so existence pluralists may want to try to treat the ontological question as distinct from the Extension Question (for them, see  §2.2).
